Neural reflexes occupy a central role in physiological homeostasis. The vagus nerve is a major conduit for transmitting afferent and efferent signals in homeostatic reflex arcs between the body and the brain. Recent advances in neuroscience, immunology, and physiology have revealed important vagus nerve mechanisms in suppressing inflammation and treating rheumatoid arthritis and other autoimmune conditions. Numerous clinical trials indicate that there is significant benefit to vagus nerve stimulation therapy. Although many questions are still unanswered, it will be important, even necessary, to pursue answers that will be useful in guiding interventions to modulate immunological and physiological homeostasis.

The Registry of Fast Myocardial Perfusion Imaging with Next-Generation SPECT (REFINE SPECT) has been expanded to include more patients and CT attenuation correction imaging. We present the design and initial results from the updated registry. Methods: The updated REFINE SPECT is a multicenter, international registry with clinical data and image files. SPECT images were processed by quantitative software and CT images by deep learning software detecting coronary artery calcium (CAC). Patients were followed for major adverse cardiovascular events (MACEs) (death, myocardial infarction, unstable angina, late revascularization). Results: The registry included scans from 45,252 patients from 13 centers (55.9% male, 64.7 ± 11.8 y). Correlating invasive coronary angiography was available for 3,786 (8.4%) patients. CT attenuation correction imaging was available for 13,405 patients. MACEs occurred in 6,514 (14.4%) patients during a median follow-up of 3.6 y (interquartile range, 2.5–4.8 y). Patients with a stress total perfusion deficit of 5% to less than 10% (unadjusted hazard ratio [HR], 2.42; 95% CI, 2.23–2.62) and a stress total perfusion deficit of at least 10% (unadjusted HR, 3.85; 95% CI, 3.56–4.16) were more likely to experience MACEs. Patients with a deep learning CAC score of 101–400 (unadjusted HR, 3.09; 95% CI, 2.57–3.72) and a CAC of more than 400 (unadjusted HR, 5.17; 95% CI, 4.41–6.05) were at increased risk of MACEs. Conclusion: The REFINE SPECT registry contains a comprehensive set of imaging and clinical variables. It will aid in understanding the value of SPECT myocardial perfusion imaging, leverage hybrid imaging, and facilitate validation of new artificial intelligence tools for improving prediction of adverse outcomes incorporating multimodality imaging.

Simplified methods of acquisition and quantification would facilitate the use of synaptic density imaging in multicenter and longitudinal studies of Alzheimer disease (AD). We validated a simplified tissue-to-reference ratio method using SUV ratios (SUVRs) for estimating synaptic density with [¹¹C]UCB-J PET. Methods: Participants included 31 older adults with AD and 16 with normal cognition. The distribution volume ratio (DVR) using simplified reference tissue model 2 was compared with SUVR at short scan windows using a whole-cerebellum reference region. Results: Synaptic density was reduced in AD participants using DVR or SUVR. SUVR using later scan windows (60–90 or 70–90 min) was minimally biased, with the strongest correlation with DVR. Effect sizes using SUVR at these late time windows were minimally reduced compared with effect sizes with DVR. Conclusion: A simplified tissue-to-reference method may be useful for multicenter and longitudinal studies seeking to measure synaptic density in AD.

The role of somatostatin receptor (SSTR) PET/CT, using ⁶⁸Ga-based tracers or [⁶⁴Cu]Cu-DOTATATE (⁶⁴Cu-DOTATATE), in the management of patients with neuroendocrine neoplasm (NEN) is guided by appropriate use criteria (AUC). In this study, we performed systematic analyses of referral patterns and image findings of routine ⁶⁴Cu-DOTATATE PET/CT scans to support AUC development. Methods: We included all clinical routine ⁶⁴Cu-DOTATATE PET/CT scans performed between April 10, 2018 (start of clinical use), and May 2, 2022, at Copenhagen University Hospital–Rigshospitalet. We reviewed the referral text and image report of each scan and classified the indication according to clinical scenarios as listed in the AUC. Results: In total, 1,290 patients underwent 2,249 ⁶⁴Cu-DOTATATE PET/CT scans. Monitoring of patients with NEN seen both on conventional imaging and on SSTR PET without clinical evidence of progression was the most common indication (defined as "may be appropriate" in the AUC) and accounted for 703 (31.3%) scans. Initial staging after NEN diagnosis ("appropriate" in the AUC) and restaging after curative-intent surgery ("may be appropriate" in the AUC) accounted for 221 (9.8%) and 241 (10.7%) scans, respectively. Selection of patients eligible for peptide receptor radionuclide therapy ("appropriate" in the AUC) and restaging after peptide receptor radionuclide therapy completion ("appropriate" in the AUC) accounted for 95 (4.2%) and 115 (5.1%) scans, respectively. The number of scans performed for indications not defined in the AUC was 371 (16.5%). Image result analysis revealed no disease in 669 scans (29.7%), stable disease in 582 (25.9%), and progression in 461 (20.5%). In 99 of the 461 (21.5%) scans, progression was detected on PET but not on CT. Conclusion: Our study provided real-life data that may contribute to support development of ⁶⁴Cu-DOTATATE/SSTR PET/CT guidelines including AUC. Some scenarios listed as "may be appropriate" in the current AUC were frequent in our data. Monitoring of patients with NEN without clinical evidence of progression was the most frequent indication for ⁶⁴Cu-DOTATATE PET/CT, in which disease progression was detected in more than one third, and a large proportion was visible by PET only. We therefore conclude that this scenario could potentially be classified as appropriate.

The positional preference of an animal can be very informative regarding the choices it makes about how to interact with its environment. The fruit fly Drosophila melanogaster has been used as a robust system for examining neurobiological mechanisms underlying behavior. Fruit fly positional preference can be gathered from TriKinetics Drosophila activity monitors (DAMs), which contain four infrared beams, allowing for tracking the position of individual flies along the length of a tube. Here, we describe a method for using DAM5Ms to examine food preference. Specifically, we show an example in which circadian changes in food preference are compared between different Drosophila species. More information about the evolution of behavior can be gathered by measuring feeding preference relative to time of day. Noni, fruit from Morinda citrifolia, contains octanoic acid, a chemical toxic to many species of Drosophila. D. melanogaster and D. simulans, both food generalists, show high sensitivity to octanoic acid, whereas D. sechellia, a specialist, can tolerate high concentrations. When two different food substrates are provided at each end of a tube, food preference can be inferred at various times of the day, using the sleep and circadian analysis MATLAB program (SCAMP) to extract and analyze positional data from DAM5Ms. Data gathered from these analyses can be used to compare avoidance or attraction to nutrients, tastants, or odors between species and genotypes or after specific different treatments. Additionally, such data can be examined as a function of time of day.

We primary care clinicians, scholars, and leaders ascribe value to Barbara Starfield’s core tenets of primary care—the 4 Cs: first contact, comprehensiveness, coordination, and continuity. In today’s era of rapid technological advancements and dwindling resources, what are the implications for face-to-face interactions of patient-clinician relationships? We propose adding a 5th C: "Contiguity." Contiguity—or physical proximity and presence—is a key dimension that not only enables the necessary technical aspects of a physical exam but also authenticates the most human aspects of a relationship and occurs specifically when we are physically vulnerable and responsible for the other before us. This, in turn, may best enable us to bridge difference and nurture trust with our patients. We measure what we value and, thus, naming Contiguity as a core tenet assures that we will not lose sight of this keystone in a patient’s relationship with their personal physician.

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 United Nations says South Sudan’s four-year-old civil war has left half of the nation’s population — 6 million people — in need of humanitarian aid. The conflict began when South Sudan’s army split between factions loyal to President Salva Kiir and former Vice President Riek Machar. The two men mobilized their respective tribes, the Dinka and the Nuer. The war has caused what is now one of the world’s worst refugee crises.

SIMONA FOLTYN: Civil war is emptying huge swaths of South Sudan. The violence has uprooted four million people, including two million who’ve fled to neighboring countries. In the last year, more than a million South Sudanese have poured into northern Uganda alone, crossing makeshift bridges like this one to flee fighting, hunger, and brutal attacks on civilians.

SEME LUPAI, REFUGEE: They started fighting very, very severely. So that made us to escape with our properties to this side.

SIMONA FOLTYN: When Seme Lupai’s family went to one of the refugee camps, initially, he stayed behind to look after the family’s most precious commodity — their cattle. He hid for a year to escape the violence. The refugees carry whatever they can salvage — mattresses, pots, clothes, notebooks — remnants of once peaceful lives turned upside down. At checkpoints, Ugandan soldiers search their belongings for weapons, before the refugees proceed to reception centers. After entering Uganda, the refugees sign in at small waystations. For many, it’s the first night spent in safety after walking for days to escape fighting. Levi Arike fled with his wife and four children.

LEVI ARIKE, REFUGEE: When the gunshots started, we laid under a tree with the whole family, because there was nowhere else to hide. We waited for the fighting to stop, and then we got up and started walking to Uganda.

SIMONA FOLTYN: Uganda now shoulders most of the burden of Africa’s biggest refugee crisis, managing a constellation of camps which require food, water, healthcare, and policing. At Imvepi Camp, now home to more than 120,000 South Sudanese, new arrivals receive vaccinations, hot meals, and basic items such as soap and plastic tarps to build a house. The government also gives each refugee family a small plot of land, about a twentieth of an acre, where they can build a tent shelter and grow crops to eat or sell. But the land often proves too rocky for farming.

SIMONA FOLTYN, IMVEPI REFUGEE CAMP, NORTHERN UGANDA: After completing the registration process, the new arrivals will receive their plot, to start a new life as refugees in Uganda. While they are safe here, there are many challenges ahead, not least processing the trauma of what they experienced back home.

This woman, who we’ll call “Agnes,” agreed to tell us about her harrowing experience. She says four government soldiers from President Salva Kiir’s Dinka tribe stopped her as she was fleeing South Sudan and raped her right in front of her family.

AGNES (translated to English): When they started raping me, they told me not to raise alarm, otherwise they would shoot me. Still when I’m sleeping, I’m dreaming of the Dinka, that they are coming to rape me again.

SIMONA FOLTYN: How often do you have those dreams?

AGNES: Daily, every time I lie down, those dreams come.

SIMONA FOLTYN: A recent Human Rights Watch report on South Sudan found “…a clear pattern of government forces unlawfully targeting civilians for killings, rapes, torture…and destruction of property..” The victims are from ethnic groups suspected to support the rebels.

AGNES: They are doing it, because they know very well that those soldiers are our brothers. So they do it to punish them..

SIMONA FOLTYN: Although the rebels, known as the Sudan People’s Liberation Army In Opposition, purport to protect local communities, there are also reports of their fighters assaulting civilians near the Ugandan border. Josephine Yanya told us she didn’t feel safe in the presence of either side’s soldiers. Her family and neighbors fled their village after government soldiers killed her uncle.

They hid in the mountains only to find themselves under attack again, this time by opposition fighters from the Nuer tribe loyal to former vice president Riek Machar. Yanya says ethnic Nuer soldiers from the SPLA-IO rebel group raped a member of her group and stole her father’s’ cattle.

JOSEPHINE YANYA (translated to English): Before we were thinking that the rebels would protect us, but if they are lacking food, they just come and take things by force.

SIMONA FOLTYN: With nowhere left to hide, Yanya fled to Uganda with her son.
But instead of finding a place to rebuild their lives, they are in limbo. And aid groups don’t have enough food to distribute.

JOSEPHINE YANYA (translated to English):We are getting small food rations. I know it won’t be enough even for one month.

SIMONA FOLTYN: According to the United Nations, the international community has given less than a-third of the $1.4 billion dollars needed for the refugee response in South Sudan’s neighboring countries. These refugees foresee more hardship and have no idea when they might return home.

JOSEPHINE YANYA (translated to English): I’m always praying for peace in South Sudan, and until then, I’ll just stay here.

More than 500,000 Rohingya Muslims have fled their homes since August to escape systematic violence at the hands of government soldiers in Myanmar. The U.N. has called the actions taken by Myanmar forces against the group “a textbook example of ethnic cleansing.”

A report released by Amnesty International on Wednesday documents widespread rape, killings and burnings of Rohingya across the Rakhine State in Myanmar. The report includes extensive interviews of Rohingya refugees who tell stories of live burnings, sexual violence and mass shootings at the hands of soldiers.

To escape persecution, Rohingya refugees are fleeing in droves to neighboring Bangladesh, a country described by some as a reluctant host for the thousands of refugees behind its borders. Conditions within Bangladesh show refugee camps beyond capacity, as organizations struggle to keep up with humanitarian aid.

Find out more: Rohingya Muslims have been denied citizenship in Myanmar since 1982, though they’ve lived in the area since the 12th century. They are not considered one of the country’s official ethnic groups. As such, their lack of official identity bars them from government services and travel.

Officials from Myanmar, a majority Buddhist state, claim Rohingya are actually immigrants from Bangladesh to justify their exclusion of the group. This most recent burst of violence comes from Myanmar’s crackdown following clashes with the Arakan Rohingya Salvation Army (ARSA). After the government declared ARSA a terrorist organization, the retaliation escalated into hundreds of Rohingya villages.

Where to give: BRAC, a top-ranked NGO based out of Bangladesh, is scaling up humanitarian efforts for clean water, health, sanitation and child care for refugees from Myanmar. You can learn more about their efforts here.

An emergency appeal was made by the Disasters Emergency Committee for immediate crisis relief funds. DEC distributes funds to 13 member aid organizations.
UNHCR, UNICEF and Save the Children have donation pages dedicated to the crisis, as does the International Rescue Committee. CNN’s Public Good page provides a user-friendly resource to find NGOs that match your giving goals.

To give to starvation relief, try Action Against Hunger or the World Food Programme.

Be sure to research organizations receiving your financial contributions, not only to find the best organization aligned with your goals, but also to avoid potential scams.

Just after the New Year, I spent some time in Vermont.

I go to Vermont to write, but ever since the start of the pandemic, I also go there for some clarity of thought. Sometimes it's easier to figure out how you're doing if you can get some distance from everything. Where I go, I have no cell service, internet, or email. I keep my fingers crossed that when I arrive, I won't discover frozen pipes. I haul a lot of wood (so much wood! Wood is heavy!). I start a fire in the stove and hole up for a while, blessed with the great good fortune to be allowed to turn briefly into a hermit.

Occasionally I'm able to talk to Kevin on the phone, and our conversations go something like this: Hi! How have you been? Could you please tell me the names of Henry VIII's wives in order and also which ones were executed? 

Because, again, I have no internet. So I keep a running list of all the things I've been wondering. And when you're listening to the audiobook of Wolf Hall while staring out the window,

sometimes you realize you want some spoilers. (The answer, if you're interested: (1) Catherine of Aragon. (2) Anne Boleyn, beheaded. (3) Jane Seymour. (4) Anne of Cleves. (5) Catherine Howard, beheaded. (6) Catherine Parr.) 

So anyway, I went to Vermont at the New Year. In previous years, I've loved the New Year. It's been a time of reflection and planning for me, a time to find balance and reconsider my intentions. Since the start of the pandemic, I've lost that New Year ritual to a certain extent, because time and its passage have gotten quite confusing. It doesn't seem possible, for example, that Winterkeep was released in 2021. Wasn't that eons ago? But also, I finalized a new book in 2021 (more on that, as soon as I'm allowed to say more) and am more than halfway through writing a new one, plus I have three other ideas begging to be written. How is that possible? Hasn't it been only a year? Didn't time used to be less springy than this? How old am I anyway? Did winter always used to make me this emotional? Why did I used to dislike my gray hair and now I love it? Why did I ever, EVER, put up with itchy tags in my clothes before now? Have my hands always been this cold? When will I see my friends' faces again?

It's really hard to sum up my last year and make plans for the next. I'm thinking in mushy blobs of time, rather than weeks, months, or years. But I am still hoping and planning. 

Here are three plans I have for the nearish future:

1. I will finish a draft of a new, contemporary book that I'm currently loving writing. (I actually think this will happen this spring!)

2. I will unveil a website. Finally, after more than a decade, I've hired someone to build me a website! I'm having so, so much fun making my own art for it. I think this will get sorted this summer.

3. I will make some strides in a project currently occupying me and some other family members: dual USA-Italian citizenship.

These are my plans. Of course, every new piece of news and frankly the world in general can gum up the works pretty easily these days. So, we'll see how everything goes. I'm trying to learn flexibility.

I hope you're able to find some flexibility too, and also some clarity of thought, as we move through the New Year.

All eyes are on Michigan as Donald Trump and Kamala Harris battle over undecided voters in the crucial swing state, including many of the state’s 200,000 Arab American and Muslim voters who reject both the Republican and Democratic parties’ stance on Israel and Palestine. We speak to Dearborn, Michigan’s Lebanese American Mayor Abdullah Hammoud, who is the first Arab and Muslim mayor of the city, about many of his constituents’ loss of support for the Democratic Party and how the Arab American vote could impact the presidential election. Hammoud, like many Dearborn residents, has lost extended family to Israel’s attacks on Lebanon, and describes the climate in the city as “a blanket of grief.” Having called for a ceasefire and arms embargo on Israel, he refused to meet with Trump last week, but has also declined to endorse Harris. Hammoud calls on voters to not sit out the election entirely, but to “vote their moral conscience, and says the citizens of Dearborn are “willing to put people over party, first and foremost.”
