ISLAMABAD: Former prime minister and senior leader of the Pakistan Muslim League-Nawaz (PML-N) Shahid Khaqan Abbasi will appear on Saturday (today) before the commission of inquiry investigating the recent shortage and price hike of sugar in the country.

Mr Abbasi told Dawn on Friday he would inform the commission how sugar scandals develop, in the light of his experience as a former chief executive of the country.

He said he had written a letter to the commission, offering his services to it by sharing his experiences in probing scams. “I wrote the letter to the commission, as under the Commission of Inquiry Act any citizen can assist such commissions in investigating such scams,” he said.

Upon receiving the letter, Mr Abbasi said, the commission asked him to provide a written statement, or any other document, that would help in investigating the scandal. “I told the commission that I will not give any written statement or document, but will assist it on the basis of my experience, I being a former member of the Economic Coordination Committee (of the cabinet) and former head of the federal cabinet,” he said.

Mr Abbasi, who served as the prime minister in the last PML-N government, said he would explain to the commission how the sugar crisis occurred.

When asked to share some of the reasons behind the crisis, the former premier said allowing export of the commodity was one of the main reasons. “The commission has to ascertain who gave the approval for export of sugar when its local demand had not been taken care of.”

He said he would request the commission to keep his meeting with its members open to all. Another PML-N leader and former defence minister Khurram Dastagir Khan would be accompanying Mr Abbasi to the meeting.

The commission is investigating the recent shortage of sugar and wheat in the country, in which some key members and allies of the ruling Pakistan Tehreek-i-Insaf were allegedly involved.

The past decade has increased our understanding of how genome topology controls RAG endonuclease-mediated assembly of lymphocyte AgR genes. New technologies have illuminated how the large IgH, Ig, TCRα/, and TCRβ loci fold into compact structures that place their numerous V gene segments in similar three-dimensional proximity to their distal recombination center composed of RAG-bound (D)J gene segments. Many studies have shown that CTCF and cohesin protein–mediated chromosome looping have fundamental roles in lymphocyte lineage- and developmental stage–specific locus compaction as well as broad usage of V segments. CTCF/cohesin–dependent loops have also been shown to direct and restrict RAG activity within chromosome domains. We summarize recent work in elucidating molecular mechanisms that govern three-dimensional chromosome organization and in investigating how these dynamic mechanisms control V(D)J recombination. We also introduce remaining questions for how CTCF/cohesin–dependent and –independent genome architectural mechanisms might regulate compaction and recombination of AgR loci.

We investigated whether cycloheximide (CHX) would induce amnesia for the stress-induced impairment of extinction retrieval. First, a single restraint stress session was demonstrated to impair extinction retrieval, but not fear conditioning. A second experiment showed that when CHX was administered immediately after restraint, rats exhibited significant extinction retrieval at test (i.e., retrograde amnesia for the stress). In a third experiment, the stress session impaired various amounts of extinction durations, suggesting that the stress inhibited extinction retrieval rather than enhancing the original fear learning. These results suggest memories for acute stress are susceptible to disruption, which could have clinical implications.

BackgroundA brief intervention whereby GPs opportunistically facilitate an NHS-funded referral to a weight loss programme is clinically and cost-effective.AimTo test the acceptability of a brief intervention and attendance at a weight loss programme when GPs facilitate a referral that requires patients to pay for the service.Design and settingAn observational study of the effect of a GP encouraging attendance at a weight loss programme requiring self-payment in the West Midlands from 16 October 2018 to 30 November 2018, to compare with a previous trial in England in which the service was NHS-funded.MethodSixty patients with obesity who consecutively attended primary care appointments received an opportunistic brief intervention by a GP to endorse and offer a referral to a weight loss programme at the patient’s own expense. Participants were randomised to GPs who either stated the weekly monetary cost of the programme (basic cost) or who compared the weekly cost to an everyday discretionary item (cost comparison). Participants were subsequently asked to report whether they had attended a weight loss programme.ResultsOverall, 47% of participants (n = 28) accepted the referral; 50% (n = 15) in the basic cost group and 43% (n = 13) in the cost comparison group. This was significantly less than in a previous study when the programme was NHS-funded (77%, n = 722/940; P<0.0001). Most participants reported the intervention to be helpful/very helpful and appropriate/very appropriate (78%, n = 46/59 and 85%, n = 50/59, respectively) but scores were significantly lower than when the programme was NHS-funded (92% n = 851/922 and 88% n = 813/922, respectively; P = 0.004). One person (2%) attended the weight loss programme, which is significantly lower than the 40% of participants who attended when the programme was NHS-funded (P<0.0001).ConclusionGP referral to a weight loss programme that requires patients to pay rather than offering an NHS-funded programme is acceptable; however, it results in almost no attendance.

The American Board of Family Medicine routinely surveys its Diplomates in each national graduating cohort 3 years out of training. These data were used to characterize early career family physicians whose services include management of pregnancy and prescribing buprenorphine. A total of 261 (5.1%) respondents both provide maternity care and prescribe buprenorphine. Family physicians who care for pregnant women and also prescribe buprenorphine represented 50.4% of all buprenorphine prescribers. The family physicians in this group were trained in a small number of residency programs, with only 15 programs producing at least 25% of graduates who do this work.

Plasma DNA fragmentomics is an emerging area of research covering plasma DNA sizes, end points, and nucleosome footprints. In the present study, we found a significant increase in the diversity of plasma DNA end motifs in patients with hepatocellular carcinoma (HCC). Compared with patients without HCC, patients with HCC showed a preferential pattern of 4-mer end motifs. In particular, the abundance of plasma DNA motif CCCA was much lower in patients with HCC than in subjects without HCC. The aberrant end motifs were also observed in patients with other cancer types, including colorectal cancer, lung cancer, nasopharyngeal carcinoma, and head and neck squamous cell carcinoma. We further observed that the profile of plasma DNA end motifs originating from the same organ, such as the liver, placenta, and hematopoietic cells, generally clustered together. The profile of end motifs may therefore serve as a class of biomarkers for liquid biopsy in oncology, noninvasive prenatal testing, and transplantation monitoring.

BRAF^V600 mutations occur in a wide range of tumor types, and RAF inhibition has become standard in several of these cancers. Despite this progress, BRAF^V600 mutations have historically been considered a clear demonstration of tumor lineage context–dependent oncogene addiction, based predominantly on the insensitivity to RAF inhibition in colorectal cancer. However, the true broader activity of RAF inhibition pan-cancer remains incompletely understood. To address this, we conducted a multicohort "basket" study of the BRAF inhibitor vemurafenib in non-melanoma BRAF^V600 mutation–positive solid tumors. In total, 172 patients with 26 unique cancer types were treated, achieving an overall response rate of 33% and median duration of response of 13 months. Responses were observed in 13 unique cancer types, including historically treatment-refractory tumor types such as cholangiocarcinoma, sarcoma, glioma, neuroendocrine carcinoma, and salivary gland carcinomas. Collectively, these data demonstrate that single-agent BRAF inhibition has broader clinical activity than previously recognized.

As the COVID-19 pandemic worsens, the clinical cancer community is grappling with how to continue providing access to experimental but potentially lifesaving therapies while keeping immunocompromised patients safe. To that end, cancer centers are making changes to their clinical trial programs, while pharmaceutical companies are deciding how—or whether—trials should continue.
