Abstract
Background
Malnutrition continues to be a major cause of mortality and morbidity among children in resource limited settings. Children with severe acute malnutrition (SAM) experience severe thymus atrophy, possibly reflecting poor immune function. This immune dysfunction is responsible for the severe infections they experience which lead to mortality. Since their immune dysfunction is not fully understood and there has been a lapse in research in this field, more research is needed. Knowing the correlates of thymus size may help clinicians identify those with more severe atrophy who might have more severe immune impairment. We aimed to describe thymus size and its correlates at admission among children hospitalized with SAM.

Methods
This cross-sectional study involved children 6-59 months admitted with complicated SAM in Mulago National Referral Hospital. Well-nourished children from same communities were used as a community reference group for thymus size. At admission, thymus size was measured by ultrasound scan. Demographic, clinical and laboratory variables were identified at admission. A linear regression model was used to determine correlates of thymus size among children with SAM.

Results
Among 388 children with SAM, the mean age was 17±8.5 months and 58% were boys. The mean thymus size was 3.14 (95% CI 2.9; 3.4) cm2 lower than that of the 27 healthy community reference children (1.06 vs 4.2 cm2, p<0.001) when controlled for age. Thymus size positively correlated with current breastfeeding (0.14, 95% CI 0.01, 0.26), anthropometric measurements at admission (weight, length, mid-upper-arm circumference, weight-for-height Z scores and length-for-age Z scores) and suspected tuberculosis (0.12, 95% CI 0.01; 0.22). Thymus size negatively correlated with > 2 weeks duration of sickness (-0.10; 95% CI -0.19; -0.01).

Conclusion
The thymus is indeed a barometer for nutrition since all anthropometric measurements and breastfeeding were associated with bigger thymus. The immune benefits of breastfeeding among children with SAM is underscored. Children with longer duration of illness had a smaller thymus gland indicating that infections have a role in the cause or consequence of thymus atrophy.

Abstract
Background
Domestic violence against women during pregnancy and the postpartum period not only violates the human rights of women but also harms on the health of both mother and child. Domestic violence is entrenching in social norms, customs and structural factors against women in Nepal. The use of alcohol also exacerbates domestic violence. The objective of this study was to determine the association between domestic violence against women and husband’s drinking behavior across the periods of pregnancy and postpartum.

Methods
This study was a cross-sectional study conducted in the antenatal care and postnatal care clinics of a government hospital in Kathmandu district. Among 660 women (aged 15–49), 165 women were consecutively recruited from each trimester of pregnancy and the postpartum period. Adjusted odds ratios (AOR) were computed from a multivariate logistic regression model to determine the association between domestic violence against women and the husband’s drinking behavior.

Results
Women whose husbands drank alcohol were twice as likely to suffer from domestic violence, compared to those women whose husbands did not drink (AOR = 2.12; 95% CI: 1.4–3.2), independently of their socio-demographic status. Women suffered from domestic violence in each period of pregnancy and postpartum due to their husband’s drinking habits, but the most affected period was the second trimester of pregnancy. Among women who suffered from physical, psychological and sexual violence during the pregnancy and postpartum periods, 70.2, 67.9, and 64.2% respectively experienced violence due to their husband’s drinking habit. Other associated factors for domestic violence included the ethnic culture of Janjati ethnicity, illiteracy of the women, duration of marriage 2–5 years (compared to one year or less) and a husband who behaved in a controlling manner.

Conclusions
Having a husband who has alcohol drinking behavior is an important risk factor for domestic violence against women in the pregnancy and postpartum periods. Screening of alcohol use in husbands will not prevent domestic violence but could lead to a referral to integrated treatment for alcohol and domestic violence treatment.

Abstract
Background
Mesentericoportal vein (MPV) resection in pancreatic ductal adenocarcinoma (PDAC) surgery has become a common procedure. A few studies had described the use of falciform ligament (FL) for MPV reconstruction and received encouraging preliminary effects.

Aims
This study was designed to explore the feasibility and efficacy of this technique compared with others.

Methods
Patients who underwent pancreaticoduodenectomy (PD) with MPV resection for PDAC from 2009 to 2018 were enrolled. Medical records were retrospectively reviewed, MPV reconstructions using FL were distinguished and compared with other techniques.

Results
146 patients underwent MPV reconstruction, and 13 received FL venoplasty. Other reconstruction techniques included primary end-to-end anastomosis (primary, n = 30), lateral venorrhaphy (LV, n = 19), polytetrafluoroethylene conduit interposition (PTFE, n = 24), iliac artery (IA) allografts interposition (n = 47), and portal vein (PV) allografts interposition (n = 13). FL group holds the advantages of shortest operation time (p = 0.023), lowest blood loss (p = 0.109), and shortest postoperative hospital stay (p = 0.125). The grouped patency rates of FL, primary, LV, PTFE, IA, and PV were 100%, 90%, 68%, 54%, 68%, and 85% respectively. Comparison displayed that FL had the highest patency rate (p = 0.008) and lowest antiplatelet/anticoagulation proportion (p = 0.000). Complications and long-term survival were similar among different techniques. The median survival time of patent group (24.0 months, 95% CI: 22.0–26.0) was much longer than that of the thrombosed (17.0 months, 95% CI: 13.7–20.3), though without significant difference (P = 0.148).

Conclusions
PD with MPV resection and reconstruction by FL is safe, feasible, and efficacious, it might provide a potential benefit for patients.

AbstractBackgroundMakerere University implemented a One Health Institute (OHI) in 2016 involving undergraduate students selected from different disciplines. The students were first taken through theoretical principles of One Health followed by a field attachment in communities. The field attachment aimed to expose students to experiential educational opportunities in the communities in a One Health approach. In this paper, we present students’ experiences and their contributions to the communities of attachment.MethodsThis was a cross-sectional study, utilizing qualitative data collection methods. The study involved students who participated in the OHI field attachment and community members in a One Health demonstration site-Western Uganda. Four focus group discussions (FGDs) and four in-depths interviews (IDIs) were conducted among the students, while four FGDs and twelve IDIs were conducted among community members. All interviews were audio-recorded, transcribed and analysed manually.ResultsThe four themes that emerged are: students’ understanding and appreciation of One Health concept, their experiences and gains from the multi-disciplinary field attachment, students’ contributions to the community, and challenges faced by the students. Students had good knowledge of One Health. They appreciated that health cannot be achieved by one discipline or sector and thus the need to collaborate across sectors. Regarding experiences and gains during the multi-disciplinary field attachment, the students appreciated that each discipline had a role to play in achieving health in the community. They appreciated the training citing skills gained in communication, team work and collaboration. They also reported a feeling of gratitude and accomplishment because they felt they made a positive change to the community by putting in place interventions to address some of the community challenges. Similarly, the communities appreciated the students’ contribution in solving their health challenges, ranging from conducting health education to improving sanitation and hygiene.ConclusionsThrough the OHI, students gained One Health competencies including communication, teamwork, and collaboration. Adopting an interdisciplinary model in university teaching system especially during field placement would strengthen skills of collaboration, team work and communication which are critical for a multi-disciplinary approach which is needed among the future workforce in order to solve the current health challenges.
Discovering healthcare provider behavior patterns through the lens of Medicare excess charge
Authors: Sen Sagnika , Deokar Amit V. 
Published: January 2021

Abstract
Background
The phenomenon of excess charge, where a healthcare service provider bills Medicare beyond the limit allowed for a medical procedure, is quite common in the United States public healthcare system. For example, in 2014, healthcare providers charged an average of 3.27 times (and up to 528 times) the allowable limit for cataract surgery. Previous research contends that such excess charges may be indicative of the actual amount that providers bill to non-Medicare patients and subsequent cost-shifting behavior, where a healthcare provider tries to recoup underpayment by Medicare from privately insured, self-pay, out-of-network, and uninsured patients.

Objectives
The objective of this study is to examine the drivers of a provider’s excess charge patterns, especially the extent to which the degree of excess charges may be associated with physician characteristics, Medicare reimbursement policy, or socioeconomic status and demographics of a provider’s patient base.

Methods
Using data from the 2014 Medicare Provider Utilization files, we identify three procedures with the highest variation in Medicare reimbursements to study the excess charge phenomenon. We then employ a two-step cluster analysis within each procedure to identify distinct provider groups.

Results
Each procedure code yielded distinct healthcare provider segments with specific patient demographics and related behavior patterns. Cluster silhouette coefficients indicate that these segments are unique. Three random subsamples from each procedure establish the stability of the clusters.

Conclusions
For each of the three procedures investigated in this study, a sizeable number of healthcare providers serving poorer, riskier patients are often paid significantly lower than their peers, and subsequently have the highest excess charges. For some providers, excess charges reveal possible cost-shifting to private insurance. Patterns of excess charges also indicate an imbalance of market power, especially in areas with lower provider competition and access to health care, thus leading to urban-rural healthcare disparities. Our results reinforce the call for price transparency and an upper limit to overbilling.

Published: January 2021

Abstract
Background
The Astana Declaration on Primary Health Care reiterated that PHC is a cornerstone of a sustainable health system for universal health coverage (UHC) and health-related Sustainable Development Goals. It called for governments to give high priority to PHC in partnership with their public and private sector organisations and other stakeholders. Each country has a unique path towards UHC, and different models for public-private partnerships (PPPs) are possible. The goal of this paper is to examine evidence on the use of PPPs in the provision of PHC services, reported challenges and recommendations.

Methods
We systematically reviewed peer-reviewed studies in six databases (ScienceDirect, Ovid Medline, PubMed, Web of Science, Embase, and Scopus) and supplemented it by the search of grey literature. PRISMA reporting guidelines were followed.

Results
Sixty-one studies were included in the final review. Results showed that most PPPs projects were conducted to increase access and to facilitate the provision of prevention and treatment services (i.e., tuberculosis, education and health promotion, malaria, and HIV/AIDS services) for certain target groups. Most projects reported challenges of providing PHC via PPPs in the starting and implementation phases. The reported challenges and recommendations on how to overcome them related to education, management, human resources, financial resources, information, and technology systems aspects.

Conclusion
Despite various challenges, PPPs in PHC can facilitate access to health care services, especially in remote areas. Governments should consider long-term plans and sustainable policies to start PPPs in PHC and should not ignore local needs and context.

Published: January 2021

Abstract
Background
Circular RNAs (circRNAs) have caught increasing attentions and interests for their important involvement in cancer initiation and progression. This study aims to investigate the biological functions of circNOL10 and its potential molecular mechanisms in breast cancer (BC).

Materials and methods
qRT-PCR and western blot assays were performed to measure the expression of related genes. CCK-8, colony formation, flow cytomerty and transwell assays were used to assess cell proliferation, cell cycle, migration and invasion. RNA pull-down, luciferase reporter and RIP assays were applied to address the potential regulatory mechanism of circNOL10.

Results
CircNOL10 was down-regulated in BC tissues and cells. Low expression of circNOL10 was associated with larger tumor size, advanced TNM stage, lymph node metastasis and unfavorable prognosis. Overexpression of circNOL10 inhibited cell proliferation, migration, invasion and EMT in vitro and slowed xenograft tumor growth in vivo. Mechanistically, circNOL10 could act as a molecular sponge for miR-767-5p, leading to the up-regulation of suppressors of cytokine signaling 2 (SOCS2) and inactivation of JAK2/STAT5 pathway. Moreover, circNOL10-mediated suppression of malignant phenotypes was attenuated by miR-767-5p. Similar to circNOL10, enforced expression of SOCS2 also resulted in the suppression of cell proliferation and metastasis. Furthermore, knockdown of SOCS2 reversed the tumor-suppressive effect induced by circNOL10.

Conclusions
CircNOL10 repressed BC development via inactivation of JAK2/STAT5 signaling by regulating miR-767-5p/SOCS2 axis. Our findings offer the possibility of exploiting circNOL10 as a therapeutic and prognostic target for BC patients.

AbstractBackgroundTofogliflozin, an SGLT2 inhibitor, is associated with favorable metabolic effects, including improved glycemic control and serum lipid profile and decreased body weight, visceral adipose tissue, and blood pressure (BP). This study evaluated the effects of tofogliflozin on the brachial-ankle pulse wave velocity (baPWV) in patients with type 2 diabetes (T2DM) without a history of apparent cardiovascular disease.MethodsThe using tofogliflozin for possible better intervention against atherosclerosis for type 2 diabetes patients (UTOPIA) trial is a prospective, randomized, open-label, multicenter, parallel-group, comparative study. As one of the prespecified secondary outcomes, changes in baPWV over 104 weeks were evaluated in 154 individuals (80 in the tofogliflozin group and 74 in the conventional treatment group) who completed baPWV measurement at baseline.ResultsIn a mixed-effects model, the progression in the right, left, and mean baPWV over 104 weeks was significantly attenuated with tofogliflozin compared to that with conventional treatment (– 109.3 [– 184.3, – 34.3] (mean change [95% CI] cm/s,p = 0.005; – 98.3 [– 172.6, – 24.1] cm/s,p = 0.010; – 104.7 [– 177.0, – 32.4] cm/s,p = 0.005, respectively). Similar findings were obtained even after adjusting the mixed-effects models for traditional cardiovascular risk factors, including body mass index (BMI), glycated hemoglobin (HbA1c), total cholesterol, high-density lipoprotein (HDL)-cholesterol, triglyceride, systolic blood pressure (SBP), hypertension, smoking, and/or administration of drugs, including hypoglycemic agents, antihypertensive agents, statins, and anti-platelets, at baseline. The findings of the analysis of covariance (ANCOVA) models, which included the treatment group, baseline baPWV, and traditional cardiovascular risk factors, resembled those generated by the mixed-effects models.ConclusionsTofogliflozin significantly inhibited the increased baPWV in patients with T2DM without a history of apparent cardiovascular disease, suggesting that tofogliflozin suppressed the progression of arterial stiffness.Trial RegistrationUMIN000017607.

Published: January 2021

AbstractBackgroundCytokine release syndrome (CRS) is a systemic inflammatory response characterized by the overexpression of inflammatory genes. Controlling CRS is essential for improving the therapeutic effects of chimeric antigen receptor (CAR) engineered T cells. However, current treatment options are limited given the complexity of cytokine interactions so it is important to seek a mild strategy with broad-spectrum inhibition to overcome this challenge.MethodsUsing THZ1, a covalent inhibitor of cyclin-dependent kinase 7 (CDK7), we demonstrated the transcriptional suppression of inflammatory genes in activated macrophages. RNA sequencing and ChIP sequencing were conducted to identify the key target genes of the inflammatory response. Pathogen- and CAR T cell-induced CRS models were also established to assess the efficacy and safety of targeting CDK7.ResultsCDK7 blockade attenuated cytokine release, mitigated hyperinflammatory states and rescued mice from lethal CRS. Targeting CDK7 preferentially suppressed a set of inflammatory genes, of which STAT1 and IL1 were the key targets associated with super enhancers. Furthermore, we confirmed the potent efficacy of THZ1 in alleviating the CRS induced by CAR T cell infusion without causing tissue injury or impairing antitumor effects.ConclusionsOur work indicates the CDK7-dependent transcription addiction of inflammatory genes. Targeting CDK7 is a promising strategy for treating CRS by inhibiting multiple cytokines.

AbstractSkin is the body’s first barrier against external pathogens that maintains the homeostasis of the body. Any serious damage to the skin could have an impact on human health and quality of life. Tissue engineering aims to improve the quality of damaged tissue regeneration. One of the most effective treatments for skin tissue regeneration is to improve angiogenesis during the healing period. Over the last decade, there has been an impressive growth of new potential applications for nanobiomaterials in tissue engineering. Various approaches have been developed to improve the rate and quality of the healing process using angiogenic nanomaterials. In this review, we focused on molecular mechanisms and key factors in angiogenesis, the role of nanobiomaterials in angiogenesis, and scaffold-based tissue engineering approaches for accelerated wound healing based on improved angiogenesis.
