Sleep is a fundamental feature of life for virtually all multicellular animals, but many questions remain about how sleep is regulated by circadian rhythms, homeostatic sleep drive that builds up with wakefulness, and modifying factors such as hunger or social interactions, as well as about the biological functions of sleep. Substantial headway has been made in the study of both circadian rhythms and sleep in the fruit fly Drosophila melanogaster, much of it through studies of individual fly activity using Drosophila activity monitors (DAMs). Here, we describe approaches for the activation of specific neurons of interest using optogenetics (involving genetic modifications that allow for light-based neuronal activation) and thermogenetics (involving genetic modifications that allow for temperature-based neuronal activation) so that researchers can evaluate the roles of those neurons in controlling rest and activity behavior. In this protocol, we describe how to set up a rig for simultaneous optogenetic or thermogenetic stimulation and activity monitoring for analysis of sleep and circadian rhythms in Drosophila, how to raise appropriate flies, and how to perform the experiment. This protocol will allow researchers to assess the causative role in the regulation of sleep and activity rhythms of any genetically tractable subset of cells.

BackgroundDuring the COVID-19 pandemic, global trends of reduced healthcare-seeking behaviour were observed. This raises concerns about the consequences of healthcare avoidance for population health.AimTo determine the association between healthcare avoidance during the early stages of the COVID-19 pandemic and all-cause mortality.Design and settingThis was a 32-month follow-up within the population-based Rotterdam Study, after sending a COVID-19 questionnaire at the onset of the pandemic in April 2020 to all communty dwelling participants (n = 6241/8732, response rate 71.5%).MethodCox proportional hazards models assessed the risk of all-cause mortality among respondents who avoided health care because of the COVID-19 pandemic. Mortality status was collected through municipality registries and medical records.ResultsOf 5656 respondents, one-fifth avoided health care because of the COVID-19 pandemic (n = 1143). Compared with non-avoiders, those who avoided health care more often reported symptoms of depression (n = 357, 31.2% versus n = 554, 12.3%) and anxiety (n = 340, 29.7% versus n = 549, 12.2%), and more often rated their health as poor to fair (n = 336, 29.4% versus n = 457, 10.1%) . Those who avoided health care had an increased adjusted risk of all-cause mortality (hazard ratio [HR] 1.30, 95% confidence interval [CI] = 1.01 to 1.67), which remained nearly identical after adjustment for history of any non-communicable disease (HR 1.20, 95% CI = 0.93 to 1.54). However, this association attenuated after additional adjustment for mental and physical self-perceived health factors (HR 0.93, 95% CI = 0.71 to 1.20).ConclusionThis study found an increased risk of all-cause mortality among individuals who avoided health care during COVID-19. These individuals were characterised by poor mental and physical self-perceived health. Therefore, interventions should be targeted to these vulnerable individuals to safeguard their access to primary and specialist care to limit health disparities, inside and beyond healthcare crises.

BackgroundLong-term health conditions are major challenges for care systems. Social prescribing link workers have been introduced via primary care networks (PCNs) across England since 2019 to address the wider determinants of health by connecting individuals to activities, groups, or services within their local community.AimTo assess whether the rollout of social prescribing link workers was in areas with the highest need.Design and settingA retrospective study of social prescribing link workers in England from 2019 to 2023.MethodWorkforce, population, survey, and area-level data at the PCN-level from April 2020 to October 2023 were combined. Population need before the rollout of link workers was measured using reported lack of support from local services in the 2019 General Practice Patient Survey. To assess if rollout reflected need, linear regression was used to relate provision of link workers (measured by full-time equivalent [FTE] per 10 000 patients) in each quarter to population need for support.ResultsPopulations in urban, more deprived areas and with higher proportions of people from minority ethnic groups had the highest reported lack of support. Geographically these were in the North West and London. Initially, there was no association between need and provision; then from July 2022, this became negative and significant. By October 2023, a 10-percentage point higher need for support was associated with a 0.035 (95% confidence interval = −0.634 to −0.066) lower FTE per 10 000 patients.ConclusionRollout of link workers has not been sufficiently targeted at areas with the highest need. Future deployments should be targeted at those areas.

BackgroundMost people with type 2 diabetes receive treatment in primary care by GPs who are not specialised in diabetes. Thus, it is important to uncover the most essential information needs regarding type 2 diabetes in general practice.AimTo identify information needs related to type 2 diabetes for GPs.Design and settingSystematic review focused on literature relating to Western countries.MethodMEDLINE, Embase, PsycInfo and CINAHL were searched from inception to January 2024. Two researchers conducted the selection process, and citation searches were performed to identify any relevant articles missed by the database search. Quality appraisal was conducted with the Mixed Methods Appraisal Tool. Meaning units were coded individually, grouped into categories, and then studies were summarised within the context of these categories using narrative synthesis. An evidence map was created to highlight research gaps.ResultsThirty-nine included studies revealed eight main categories and 36 subcategories of information needs. Categories were organised into a comprehensive hierarchical model of information needs, suggesting ‘Knowledge of guidelines’ and ‘Reasons for referral’ as general information needs alongside more specific needs on ‘Medication’, ‘Management’, ‘Complications’, ‘Diagnosis’, ‘Risk factors’, and ‘Screening for diabetes’. The evidence map provides readers with the opportunity to explore the characteristics of the included studies in detail.ConclusionThis systematic review provides GPs, policymakers, and researchers with a hierarchical model of information and educational needs for GPs, and an evidence map showing gaps in the current literature. Information needs about clinical guidelines and reasons for referral to specialised care overlapped with needs for more specific information.

BackgroundThere has been significant investment in pharmacists working in UK general practice to improve the effective and safe use of medicines. However, evidence of how to optimise collaboration between GPs and pharmacists in the context of polypharmacy (multiple medication) is lacking.AimTo explore GP and pharmacist views and experiences of in-person, interprofessional collaborative discussions (IPCDs) as part of a complex intervention to optimise medication use for patients with polypharmacy in general practice.Design and settingA mixed-method process evaluation embedded within the Improving Medicines use in People with Polypharmacy in Primary Care (IMPPP) trial conducted in Bristol and the West Midlands, between February 2021 and September 2023.MethodAudio-recordings of IPCDs between GPs and pharmacists, along with individual semi-structured interviews to explore their reflections on these discussions, were used. All recordings were transcribed verbatim and analysed thematically.ResultsA total of 14 practices took part in the process evaluation from February 2022 to September 2023; 17 IPCD meetings were audio-recorded, discussing 30 patients (range 1–6 patients per meeting). In all, six GPs and 13 pharmacists were interviewed. The IPCD was highly valued by GPs and pharmacists who described benefits, including: strengthening their working relationship; gaining in confidence to manage more complex patients; and learning from each other. It was often challenging, however, to find time for the IPCDs.ConclusionThe model of IPCD used in this study provided protected time for GPs and pharmacists to work together to deliver whole-patient care, with both professions finding this beneficial. Protected time for interprofessional liaison and collaboration, and structured interventions may facilitate improved patient care.

Practicing family medicine is really hard; the emotional toll of sharing patients’ distress, vulnerability, and trauma can build up and become overwhelming. A family physician experienced such a moment during one particularly complex morning. Feeling nearly ready to walk out of patient care, she reached out to the team nurse, who helped her get through the moment and re-engage with the waiting patients. Sharing vulnerability in the moment, and later reflecting and deciding to write about it shows the power of prioritizing teamwork in practice.

The usual challenges of conducting primary care research, including randomized trials, have been exacerbated, and new ones identified, during the COVID-19 pandemic. HOMER (Home versus Office for Medication Enhanced Recovery; subsequently, Comparing Home, Office, and Telehealth Induction for Medication Enhanced Recovery) is a pragmatic, comparative-effectiveness research trial that aims to answer a key question from patients and clinicians: What is the best setting in which to start treatment with buprenorphine for opioid use disorder for this patient at this time? In this article, we describe the difficult journey to find the answer. The HOMER study began as a randomized trial comparing treatment outcomes in patients starting treatment with buprenorphine via induction at home (unobserved) vs in the office (observed, synchronous). The study aimed to enroll 1,000 participants from 100 diverse primary care practices associated with the State Networks of Colorado Ambulatory Practices and Partners and the American Academy of Family Physicians National Research Network. The research team faced unexpected challenges related to the COVID-19 pandemic and dramatic changes in the opioid epidemic. These challenges required changes to the study design, protocol, recruitment intensity, and funding conversations, as well as patience. As this is a participatory research study, we sought, documented, and responded to practice and patient requests for adaptations. Changes included adding a third study arm using telehealth induction (observed via telephone or video, synchronous) and switching to a comprehensive cohort design to answer meaningful patient-centered research questions. Using a narrative approach based on the Greek myth of Homer, we describe here the challenges and adaptations that have provided the opportunity for HOMER to thrive and find the way home. These clinical trial strategies may apply to other studies faced with similar cultural and extreme circumstances.

PURPOSE

HIV pre-exposure prophylaxis (PrEP) may increase rates of bacterial sexually transmitted infections (STIs) among gay, bisexual, and other men who have sex with men (GBM) through risk compensation (eg, an increase in condomless sex or number of partners); however, longitudinal studies exploring the time-dependent nature of PrEP uptake and bacterial STIs are limited. We used marginal structural models to estimate the effect of PrEP uptake on STI incidence.

Patient expectations of receiving antibiotics for common symptoms can trigger unnecessary use. We conducted a survey (n = 564) between January 2020 to June 2021 in public and private primary care clinics in Texas to study the prevalence and predictors of patients’ antibiotic expectations for common symptoms/illnesses. We surveyed Black patients (33%) and Hispanic/Latine patients (47%), and over 93% expected to receive an antibiotic for at least 1 of the 5 pre-defined symptoms/illnesses. Public clinic patients were nearly twice as likely to expect antibiotics for sore throat, diarrhea, and cold/flu than private clinic patients. Lack of knowledge of potential risks of antibiotic use was associated with increased antibiotic expectations for diarrhea (odds ratio [OR] = 1.6; 95% CI, 1.1-2.4) and cold/flu symptoms (OR = 2.9; 95% CI, 2.0-4.4). Lower education and inadequate health literacy were predictors of antibiotic expectations for diarrhea. Future antibiotic stewardship interventions should tailor patient education materials to include information on antibiotic risks and guidance on appropriate antibiotic indications.

PURPOSE

The impact of digital health on medically underserved patients is unclear. This study aimed to determine the early impact of a digital innovation to grow quality care through an interprofessional care team (DIG IT) on the blood pressure (BP) and 10-year atherosclerotic cardiovascular disease (ASCVD) risk score of medically underserved patients.

PURPOSE

Meeting scholarly activity requirements continues to be a challenge in many family medicine (FM) residency programs. Studies comprehensively describing FM resident scholarship have been limited. We sought to identify institutional factors associated with increased scholarly output and meeting requirements of the Accreditation Council for Graduate Medical Education (ACGME).

PURPOSE

We undertook a trial to test the efficacy of a technology-assisted health coaching intervention for weight management, called Goals for Eating and Moving (GEM), within primary care.

PURPOSE

Despite being key to better health outcomes for patients from racial and ethnic minority groups, the proportion of underrepresented in medicine (URiM) physicians remains low in the US health care system. This study linked a nationally representative sample of family physicians (FPs) with Medicaid claims data to explore the relative contributions to care of Medicaid populations by FP race and ethnicity.

PURPOSE

Currently, 40% of counties in the United States do not have an obstetrician or midwife, and in rural areas the likelihood of childbirth being attended to by a family medicine (FM) physician is increasing. We sought to characterize the effect of the FM presence on unit culture and a key perinatal quality metric in Iowa hospital intrapartum units.

Redox reactions control fundamental biochemical processes, including energy production, metabolism, respiration, detoxification, and signal transduction. Cancer cells, due to their generally active metabolism for sustained proliferation, produce high levels of reactive oxygen species (ROS) compared to normal cells and are equipped with antioxidant defense systems to counteract the detrimental effects of ROS to maintain redox homeostasis. The KEAP1-NRF2 system plays a major role in sensing and regulating endogenous antioxidant defenses in both normal and cancer cells, creating a bivalent contribution of NRF2 to cancer prevention and therapy. Cancer cells hijack the NRF2-dependent antioxidant program and exploit a very unique metabolism as a trade-off for enhanced antioxidant capacity. This work provides an overview of redox metabolism in cancer cells, highlighting the role of the KEAP1-NRF2 system, selenoproteins, sulfur metabolism, heme/iron metabolism, and antioxidants. Finally, we describe therapeutic approaches that can be leveraged to target redox metabolism in cancer.

Vision is initiated by capturing photons in highly specialized sensory cilia known as the photoreceptor outer segment. Because of its lipid and protein composition, the outer segments are prone to photo-oxidation, requiring photoreceptors to have robust antioxidant defenses and high metabolic synthesis rates to regenerate the outer segments every 10 days. Both processes required high levels of glucose uptake and utilization. Retinitis pigmentosa is a prevalent form of inherited retinal degeneration characterized by initial loss of low-light vision caused by the death of rod photoreceptors. In this disease, rods die as a direct effect of an inherited mutation. Following the loss of rods, cones eventually degenerate, resulting in complete blindness. The progression of vision loss in retinitis pigmentosa suggested that rod photoreceptors were necessary to maintain healthy cones. We identified a protein secreted by rods that functions to promote cone survival, and we named it rod-derived cone viability factor (RdCVF). RdCVF is encoded by an alternative splice product of the nucleoredoxin-like 1 (NXNL1) gene, and RdCVF was found to accelerate the uptake of glucose by cones. Without RdCVF, cones eventually die because of compromised glucose uptake and utilization. The NXNL1 gene also encodes for the thioredoxin RdCVFL, which reduces cysteines in photoreceptor proteins that are oxidized, providing a defense against radical oxygen species. We will review here the main steps of discovering this novel intercellular signaling currently under translation as a broad-spectrum treatment for retinitis pigmentosa.

There is conflicting evidence regarding the use of steroids in severe community-acquired pneumonia (CAP), with previous randomised controlled trials limited by small sample sizes. ESCAPe and CAPE COD are two recently published large trials on steroids in severe CAP. ESCAPe assessed the initiation of methylprednisolone within 72–96 h of hospital admission, while CAPE COD studied the use of hydrocortisone within 24 h of the development of severe CAP. ESCAPe did not show any differences in all-cause 60-day mortality or any of its secondary outcomes. CAPE COD showed that hydrocortisone improved all-cause 28-day mortality and reduced the risk of intubation or vasopressor-dependent shock. Important differences between the trials included the steroid regimens used, timing of steroid administration and baseline characteristics, with more diabetic patients included in ESCAPe. The results of CAPE COD support the initiation of hydrocortisone within 24 h of developing severe CAP, but more research is needed to evaluate long-term outcomes and optimum dosing regimens for steroids in severe CAP.

The respiratory literature, both written and in online formats, is growing exponentially. Capturing quality content, to meet the learning needs of those working in all fields of respiratory medicine and delivering it in a palatable, accessible format is challenging but paramount. In this article we discuss ways to determine the information content and review different methods of delivering this content to those who need it.

Palliative care pertains to the holistic multidimensional concept of "patient-centred" care. It is an interprofessional specialty, primarily aiming to improve quality of care for cancer patients and their families, from the time of diagnosis of malignant disease, over the continuum of cancer care, and extending after the patient's death to the period of bereavement to support the patient's family. There are various complex and frequently unmet needs of lung cancer patients and their families/caregivers, not only physical but also psychological, social, spiritual and cultural. Systematic monitoring of patients’ symptoms using validated questionnaires and patient-reported outcomes (PROs), on a regular basis, is highly encouraged and recommended in recent guidelines on the role of PRO measures in the continuum of cancer clinical care. It improves patient–physician communication, physician awareness of symptoms, symptom control, patient satisfaction, health-related quality of life and cost-effectiveness. This implies that all treating physicians should improve their skills in communication with lung cancer patients/relatives and become more familiar with this multidimensional assessment, repeatedly screening patients for palliative care needs. Therefore, they should receive education and training to develop palliative care knowledge, skills and attitudes. This review is dedicated to lung cancer palliative care essentials that should be within the competences of treating physicians, i.e. pneumologists/thoracic oncologists.

In August, fellow reporter Jason Patinkin and I crossed on foot from northern Uganda into rebel-held South Sudan. Over the course of four days, we walked more than 40 miles through the bush, escorted by rebel soldiers, to shed light on one of the world’s most underreported conflicts.

Reporting on South Sudan’s war, which began in 2013, has always been a challenge due to the risk and logistical hurdles associated with accessing remote areas where fighting takes place. But over the past year, covering the war and its humanitarian fallout has become particularly difficult. Since the beginning of this year, South Sudan’s government has banned at least 20 foreign journalists in an apparent effort to silence reporters who had a track record of critically reporting on the government.

This systematic crackdown on the foreign press (South Sudanese journalists have long risked imprisonment and death for doing their work) coincided with two important developments. In November 2016, the United Nations warned that the violence being committed against civilians in the southern region of Equatoria risked spiraling into genocide. Then, in February, the UN declared a man-made famine, warning that 100,000 people were at risk of starving to death as a result of civil war.

Journalists seeking to cover these events were left with two equally unsavory options: self-censorship or a risky trip to rebel-held parts of the country. Only a handful of journalists have attempted the latter since fighting escalated in July last year. For us, this was our second embed with the rebels this year.

We set off from a town in northern Uganda at five in the morning, bouncing along a bumpy dirt track towards the South Sudan border. Crammed into our four-wheel drive were rebel commander Martin Abucha, a dual American and South Sudanese citizen who we planned to profile for our PBS NewsHour Weekend segment, a couple of guides, and several duffle bags stuffed with our tents, sleeping bags, emergency medical kits and provisions to last us four days.

Just as the sun began to rise above a distant range of hills that we aimed to cross later that day, our car came to a halt in front of a stream. Because of the rainy reason, it carried more water than usual. It was time to disembark and start walking, or “footing,” as South Sudanese tend to call it.

We took off our shoes and waded through the stream’s chilly waters. This was the first of a many rivers we’d have to cross along the way, either on foot or in small flimsy canoes dug out from tree trunks. Each time, we dreaded the idea of falling in with our camera gear.

The first part of our journey in northern Uganda felt very much like a hike through a national park. Passing beautiful landscapes and idyllic farming villages, one could almost forget we were headed into a war zone — but we were about to get a reality check.

We had just crossed into South Sudan when out of nowhere, two dozen armed men popped out of the tall grass and surrounded us at gunpoint.

“Stop! Who are you and where are you going?” a soldier called out in Juba Arabic from his hideout no more than 20 yards away, pointing his AK47 at us. Another one next to him had a rocket-propelled grenade propped on his shoulder, also unequivocally aiming it in our direction.

Instinctively, we threw our hands in the air and exchanged a baffled glance. Had we accidentally bumped into government soldiers? Or perhaps we had come onto the “wrong” rebels? Abucha’s group, called the Sudan People’s Liberation Army In Opposition, is the biggest but not the only armed group in Equatoria, an area rife with rival militia and bandits who exploit the security vacuum left by war.

To our relief, and only after Abucha answered a series of questions, this routine security check quickly gave way to a warm welcome. The platoon would be our escort for the next four days as we trekked to their base and to Loa, Abucha’s hometown.

Keeping up with the rebels was no easy task. Given the country’s pervasive lack of basic infrastructure, South Sudanese grow up walking for dozens of miles just to go about their daily lives. For sedentary Westerners, keeping the target pace of “two meters per second” (around five miles an hour) proved challenging amid 90-degree temperatures, all while filming and plowing our way through dense, itchy elephant grass.

The upside of the cumbersome terrain was that it kept us safe. During our four-day trip, we didn’t cross a single road, instead walking along a dizzying network of narrow bush paths the rebels seemed to know like the backs of their hands. An unwanted encounter with government troops, who tended to stick to roads and move around in vehicles as opposed to on foot, was highly unlikely.

The closest we got to government-controlled area was a visit to Loa, located just two kilometers away from a main road frequently patrolled by government soldiers. We couldn’t stay long, but the hour we spent on the ground offered us a glimpse into what villages must look like in many parts of Equatoria: burned mud huts, looted schools and clinics, fallow fields and – most strikingly – no civilians.

The war has had a devastating impact on South Sudanese communities like the one in Loa, but much of it has remained out of the limelight of international media. Our four-day venture into rebel-held South Sudan offered us a rare opportunity to report ground truths, and we are thankful for that.

At least 231 people were killed and hundreds more wounded after a massive truck bomb on Saturday struck Somalia’s capital city of Mogadishu.

The Somali government has blamed the al-Qaida-linked militant group al-Shabab for the attack, and called it the deadliest ever to hit the nation.

The blast took place outside the Safari Hotel, where rescue workers dug through the rubble of collapsed buildings overnight in search of survivors. Witnesses described a devastating scene with large-scale carnage, as doctors worked feverishly to attend to the dead and injured, many badly burned.

“The hospital is overwhelmed by both dead and wounded,” Dr. Mohamed Yusuf, the director of Medina hospital located near the blast, told the Associated Press. “We also received people whose limbs were cut away by the bomb. This is really horrendous, unlike any other time in the past.”

Photos and videos of the bombing, which took place on a busy street near a section of the city housing foreign embassies, showed collapsed walls, twisted metal, and sporadic fires spewing smoke. The Qatari government said its embassy was “severely damaged” in the strike.

U.S.-backed Syrian Democratic Forces announced Tuesday that they had captured the city of Raqqa from Islamic State militants.

“Everything is finished in Raqqa, our forces have taken full control of Raqqa,” SDF spokesman Talal Sello told AFP. A formal declaration would be announced after operations to clear any remaining sleeper cells and to remove landmines in the city were completed, Sello added.

The move is a major setback for the Islamic State which considered Raqqa the de-facto capital of its self-declared caliphate. It comes on the third anniversary of the global effort to defeat ISIS.

Raqqa was the first provincial capital to fall from government control in March 2013 after it was captured by a rebel army. The army included both Syrian opposition groups and more hard line  parties including al-Nusra and the Islamic State.

A civilian government  that was established in the city divided two months later, and less than a year later ISIS recaptured Raqqa and named the the capital of their caliphate.

About 900 civilians have been killed since the the start of the five-month operation, including 570 people in coalition air raids, according to the Syrian Network for Human Rights. The Britain-based Syrian Observatory for Human Rights put the civilian death toll at 1,130 people. American journalist James Foley was beheaded in the mountains south of the city.

SDF fighters pulled down the Islamic State’s black flag from the city’s National Hospital near the city’s stadium, according to a Reuters report.

Special presidential envoy for the Global Coalition to Defeat ISIS Brett McGurk said in August that the U.S. would attempt to perform a “stabilization” in Raqqa — including demining, removing rubble from major pathways to allow trucks and equipment through, and “basic electricity, sewage, water, the basic essentials to allow populations to come back to their home.”

It is not clear when the 300,000 civilians who have fled Raqqa since April during the operation will be able to return.

JUDY WOODRUFF: But first: Sunday’s elections Austria were the latest ample of a shift to the right Europe’s politics, as 31-year-old Christian Kurz was elected chancellor on an anti-immigration platform.

He may now form a government with a far-right party founded in the 1950s by former Nazis.

That follows recent elections in Germany, where a far-right party roiled the race and dealt a blow to returning leader Angela Merkel.

In Sweden, too, there is a strong challenge from the right and a neo-Nazi group that looks stand in elections next year.

Special correspondent Malcolm Brabant ha been surveying the political landscape in Germany and Sweden, and he begins his report in Scandinavia.

MALCOLM BRABANT, Special Correspondent: In a Gothenburg parking lot, supporters of the Nordic Resistance Movement form up for what they hope will be their biggest-ever march, to propagate an ideology espoused by mother of eight Paulina Forslund.

PAULINA FORSLUND, Nordic Resistance Movement: When white becomes the minority, they will be destroyed. I want my children to have a secure future. I want them not only for them to have a secure Sweden. I want them to have a secure world. And I want other people to fight for the same thing.

MALCOLM BRABANT: When addressing her fellow neo-Nazis, Forslund’s rhetoric sharpens.

PAULINA FORSLUND (through interpreter): I’m the welder’s daughter, the forester’s grandchild. My line consists of hardworking men and women. It’s people like them we can thank for the welfare system that our lying politicians are now giving away to imported scum.

MALCOLM BRABANT: Clearly expecting trouble, the movement’s leaders have a muscular protection detail, marching past a silent protest. The sign reads “No Nazis on our streets.”

This protester would only give her name as Johanna.

JOHANNA, Anti-Nazi Protester: They are racist people. They are people who think that certain people are better than others, and I will not stand for that. It’s not something I think has a place in a modern society.

MALCOLM BRABANT: Experts say the resistance movement is recruiting aggressively, and believe this demonstration is emblematic of the rise of the far right.

It took place on Yom Kippur, the Jewish day of atonement.

Allan Stutzinky is leader of Gothenburg’s Jewish community.

ALLAN STUTZINKY, Jewish Community Leader (through interpreter): Nazism has returned. The descendants of the murderers are organizing the same marches today, waving the same flags, shouting the same slogans, and have the same racist agenda.

MALCOLM BRABANT: Anna Johansson is a member of the governing Social Democrat Party. It’s considering outlawing the Nordic Resistance Movement.

ANNA JOHANSSON, Swedish Social Democratic Party: In Sweden and in Denmark, and in other countries, extreme parties are growing, and the hatred is spreading around.

MALCOLM BRABANT: “Go home to mama,” he shouts. “Nazi pigs,” chant the anti- fascist protesters, as a bottle flies through the air.

DAMON, Nordic Resistance Movement: If someone calls themselves a Nazi, most of us would dissociate with that person. That’s nothing we stand for ourselves. I never call myself a Nazi. I’m a national socialist.

MALCOLM BRABANT: Hitler’s party was also called National Socialist, but Damon, a 40-year-old welder, insists he’s a nonviolent family man.

DAMON: The demographic landscape of our — of the whole of Europe is changing, so, basically, it’s a concern on preserving my heritage for my family and our kin.

MALCOLM BRABANT: This demonstration has been stopped short of its destination. The Nordic Resistance Movement is currently trapped between a line of police and anti-fascist protesters. And it looks as though this demonstration isn’t going any further.

Violence briefly erupts as the resistance movement tries to break through police lines, and several marchers are arrested.

PAULINA FORSLUND: We are not your enemy. We are the government’s enemy.

They say we live in a democracy, but we have never had an election about if we want to take all these people in.

MALCOLM BRABANT: When Europe’s refugee crisis began in 2015, Sweden copied Germany’s open-door policy, and 160,000 migrants entered the country. Two years on, Sweden has tighter borders and has begun deporting some of the newcomers.

The new atmosphere alarms Floid Gumbo, entertaining an anti-Nazi rally.

FLOID GUMBO, Singer Originally from Zimbabwe: I came to Sweden over 20 years ago. The climate in Sweden, the people were so friendly, and things were completely different, more welcoming. And I feel like things have sort of gradually changed.

I’m very concerned, because I have children, because I’m thinking what I experienced here is not the same kind of climate, atmosphere that they are going to experience here.

ANNA JOHANSSON: It’s not so long ago that the Nazis ruined Europe. And that makes me very worried. The German elections were terrifying, I think.

MALCOLM BRABANT: Johansson is referring to last month’s success of the right-wing Alternative For Germany Party, or AFD, when it entered Parliament for the first time with 13 percent of the vote.

HUGH BRONSON, Alternative For Germany Party: The AFD only came into existence because Merkel deserted the traditional conservative Christian voters. They were looking for a home, and the AFD has offered them a safe place.

MALCOLM BRABANT: Hugh Bronson is deputy leader of the AFD in Berlin.

Now his party, the third largest in Parliament, is demanding that Angela Merkel imposes tougher immigration rules.

Your opponents claim that you are a party of hate. What’s your response to that?

HUGH BRONSON: We embrace foreigners who respect our laws, pay their taxes, send their children to school, and go about their normal life. The problem is with people who abuse the system to have a better life, or let others pay for their better lives, or who are criminals.

MALCOLM BRABANT: Outside the opera house in Dresden, former East Germany, singer Luca Bergelt is dismayed by the political landscape shifting to the right.

LUCA BERGELT, Singer: My fear is that they will tear Europe apart. They are going to raise up the walls again. They’re going to build new walls between the countries, and that Europe will get more close into itself.

MALCOLM BRABANT: Anti-immigrant sentiment is strong in Dresden. The city was the birthplace of a pan-European anti-Islamic movement, and it delivered the largest number of votes for the right-wing party.

On a holiday to celebrate German unification after the fall of communism, retired engineer Wilfried Schmidt explained why he sent a message to Angela Merkel.

WILFRIED SCHMIDT, Retired Engineer (through interpretor): Let’s put it this way. We all need to recognize that Germany is undergoing social changes that are becoming harder to control. For one, there is mass immigration from difficult regions that is increasingly uncontrollable, of people with entirely different concepts of life, from fundamental differently structured societies that are problematic.

MALCOLM BRABANT: About one million migrants poured into Germany in 2015. Chancellor Merkel consistently defended her pro-refugee policies, but now she has been punished by voters who believe she ignored their concerns.

Chancellor Merkel has promised to listen to the people who voted for the AFD, and she says she’s going to try to win them over with what she calls good politics. But she will not countenance having the party in her coalition.

But the chancellor needs to find new partners who are prepared to be tough on immigration.

As she tries to forge a coalition, the chancellor has agreed to put an annual cap of 200,000 on the number of immigrants, something she previously refused to do. But will it be enough to woo back people who deserted her at the election?

A question for Werner Patzelt, a political scientist at Dresden University.

WERNER PATZELT, Dresden University: Since Chancellor Merkel has made so many U-turns in German domestic politics, it wouldn’t be a surprise if she would try to do a U-turn, also winning back AFD voters.

But this is a really hard political task, because so many of them are so much disappointed by the Christian Democratic Union in general, and by Chancellor Merkel in particular, that they will do anything to avoid going back.

MALCOLM BRABANT: Back in Sweden, the governing party is horrified at the concept of conceding ground to right-wingers, and is trying to isolate them.

ANNA JOHANSSON: Experience shows that, when you adopt the ideas from these right-wing parties, they spread. These parties have their agenda implemented by other parties. And I wouldn’t want to see that happen in Sweden.

FLOID GUMBO: We’re all human beings. We share this world. We’re all here. There’s enough space for us all.

MALCOLM BRABANT: But that’s an appeal that an increasing number of Swedes are rejecting, as the country and much of Europe go through a crisis of identity.
