Published: March 2023

Abstract
Tropical areas with mean upward motion—and as such the zonal-mean intertropical convergence zone (ITCZ)—are projected to contract under global warming. To understand this process, a simple model based on dry static energy and moisture equations is introduced for zonally symmetric overturning driven by sea surface temperature (SST). Processes governing ascent area fraction and zonal mean precipitation are examined for insight into Atmospheric Model Intercomparison Project (AMIP) simulations. Bulk parameters governing radiative feedbacks and moist static energy transport in the simple model are estimated from the AMIP ensemble. Uniform warming in the simple model produces ascent area contraction and precipitation intensification—similar to observations and climate models. Contributing effects include stronger water vapor radiative feedbacks, weaker cloud-radiative feedbacks, stronger convection-circulation feedbacks, and greater poleward moisture export. The simple model identifies parameters consequential for the inter-AMIP-model spread; an ensemble generated by perturbing parameters governing shortwave water vapor feedbacks and gross moist stability changes under warming tracks inter-AMIP-model variations with a correlation coefficient ∼0.46. The simple model also predicts the multimodel mean changes in tropical ascent area and precipitation with reasonable accuracy. Furthermore, the simple model reproduces relationships among ascent area precipitation, ascent strength, and ascent area fraction observed in AMIP models. A substantial portion of the inter-AMIP-model spread is traced to the spread in how moist static energy and vertical velocity profiles change under warming, which in turn impact the gross moist stability in deep convective regions—highlighting the need for observational constraints on these quantities.

Significance Statement
A large rainband straddles Earth’s tropics. Most, but not all, climate models predict that this rainband will shrink under global warming; a few models predict an expansion of the rainband. To mitigate some of this uncertainty among climate models, we build a simpler model that only contains the essential physics of rainband narrowing. We find several interconnected processes that are important. For climate models, the most important process is the efficiency with which clouds move heat and humidity out of rainy regions. This efficiency varies among climate models and appears to be a primary reason for why climate models do not agree on the rate of rainband narrowing.
A contemporaneous narrative review of Fournier’s gangrene
Authors: Desai Rajeev , Batura Deepak 
Published: March 2023

Introduction: Fournier’s gangrene is a necrotizing infection of the external genitalia, perineal or perianal regions and is mainly seen in males. Its main risk factors include diabetes, chronic alcoholism, HIV and other immune-compromised states. Fournier’s gangrene has an aggressive course associated with a mortality rate of 20%−30%, making early diagnosis and management very important. The Fournier Gangrene Severity Index (FGSI) has been traditionally used to predict the severity and prognosis. More recently, simplified FGSI (sFGSI) has been proposed and is helpful. However, timely diagnosis, supportive medical management and complete surgical debridement are still the cornerstones of treatment. These must be complemented with early and timely re-look debridements and appropriate reconstruction to cover soft tissue defects. This literature review aims to look at recent relevant research regards risk factors and prognostic features of Fournier’s gangrene. Methods: A search was conducted on Google Scholar and PubMed databases for all articles related to Fournier’s Gangrene. These included clinical reviews, case reports, case series and retrospective studies. Reports or studies which were not published in English were not reviewed. Various reconstructive techniques to cover the defects have also been revisited. Results: Broad-spectrum antibiotics and urgent surgical debridement are the core management principles of Fournier’s gangrene. Repeat debridement after 24 h is also recommended. Adjunctive therapies such as hyperbaric oxygen and vacuum-assisted closure are supported in most aspects of recent literature. Expectedly, there is a lack of randomised controlled studies in such emergency surgical conditions, which limits the widespread use of newer therapies to patients unresponsive to conventional management. Conclusion: Fournier’s gangrene is a urological emergency with a high mortality rate. The aggressive nature of the infection necessitates early recognition and immediate surgical intervention. Negative pressure dressing and occasional hyperbaric oxygen as adjuncts should be used more routinely, especially if there is a delayed response to conventional treatment or in severe infections.

Published: March 2023

Background: The roles of tight junction (TJ) proteins in peritoneal membrane transport and peritoneal dialysis (PD) require further characterisation. Dipeptidyl peptidase-4 is expressed in mesothelial cells, and its activity may affect peritoneal membrane function and morphology. Methods: Human peritoneal mesothelial cells (HPMCs) were isolated and cultured from omentum obtained during abdominal surgery, and paracellular transport functions were evaluated by measuring transmesothelial electrical resistance (TMER) and dextran flux. Sprague-Dawley rats were infused daily with 4.25% peritoneal dialysate with and without sitagliptin administration for 8 weeks. At the end of this period, rat peritoneal mesothelial cells (RPMCs) were isolated to evaluate TJ protein expression. Results: In HPMCs, the protein expression of claudin-1, claudin-15, occludin and E-cadherin was decreased by TGF-β treatment but reversed by sitagliptin co-treatment. TMER was decreased by TGF-β treatment but improved by sitagliptin co-treatment. Consistent with this, dextran flux was increased by TGF-β treatment and reversed by sitagliptin co-treatment. In the animal experiment, sitagliptin-treated rats had a lower D2/D0 glucose ratio and a higher D2/P2 creatinine ratio than PD controls during the peritoneal equilibration test. Protein expression of claudin-1, claudin-15 and E-cadherin decreased in RPMCs from PD controls but was not affected in those from sitagliptin-treated rats. Peritoneal fibrosis was induced in PD controls but ameliorated in sitagliptin-treated rats. Conclusion: The expression of TJ proteins including claudin-1 and claudin-15 was associated with transport function both in HPMCs and in a rat model of PD. Sitagliptin prevents peritoneal fibrosis in PD and can potentially restore peritoneal mesothelial cell TJ proteins.

Objective To evaluate the association between human papillomavirus vaccination status and participation in cervical cancer screening (at age 25) by the first cohorts of girls who were offered vaccination at the age of 15 to 16 years in Italy. Methods Women born in 1993, 1994 and 1995 were invited to participate in cervical cancer screening between 2018 and 2020. We report participation in screening by vaccination status in three large areas, Florence province, Piedmont region and Savona province, where the Consensus Project was carried out. The relative risk of participation among vaccinated (≥2 doses) and unvaccinated women was estimated. Odds ratios (OR) of participation by vaccination status were estimated by logistic regression, adjusted by birthplace and birth cohort. Results Overall, 34,993 women were invited for screening: 13,006 (37.2%) participated and 10,062 of these agreed to participate in the Consensus intervention study. Among the invited women and screening participants, vaccinated women were 51.0% and 60.6%, respectively. Comparing vaccinated and unvaccinated women, the adjusted OR of screening participation was 1.80 (95% confidence interval (CI): 1.72–1.89), 2.17 (95% CI: 1.94–2.42), 1.59 (95% CI: 1.50–1.68) and 1.15 (95% CI: 0.86–1.54) for overall, Florence, Piedmont and Savona, respectively. About 33% of the invited women were unvaccinated and did not participate in screening: 25.8%, 59.5% and 64.2% of women born in Italy, in high migration pressure countries and in advanced development countries, respectively. Conclusions Screening participation was higher among vaccinated than unvaccinated women. Active policies are needed to reduce inequalities, targeting the unscreened and unvaccinated population, particularly non-native women, to accelerate cervical cancer elimination in Italy.

Published: March 2023

Background Cardiovascular disease (CVD) is a group of heart disorders, which is a major cause of non-communicable disease-related mortalities worldwide. Myocardial infarction (MI) is an acute disorder due to the poor supply of oxygen and blood to the myocardium. MI is the foremost form of CVD, which is the primary cause of mortality worldwide. Objectives Here, we intended to discover the ameliorative properties of the ponicidin against the isoproterenol (ISO)-stimulated MI in rats. Materials and Methods About 85 mg/kg of ISO was administered to the rats to trigger the MI and then treated with 25 and 50 mg/kg of ponicidin. The body weight and heart weight of all rats were determined. The total protein, c-reactive protein (CRP), and uric acid levels were examined. The activities of cardiac function markers such as creatine kinase (CK), ALT, AST, and gamma-glutamyl transferase (GGT) were examined. The antioxidants such as glutathione (GSH), GST, and GPx were examined by the previous methods. The status of Na+/K+, Mg2+, and Ca2+ ATPase activities was assessed using kits. The status of Na+, K+, and Ca2+ ions and inflammatory makers such as TNF-α and IL-6 were investigated using respective kits. The histopathological analysis was performed on the heart tissues to detect the histological changes. Results The results revealed that ponicidin increased body weight and decreased heart weight in MI rats. The status of CRP and uric acid was decreased and total protein was augmented in the ponicidin-treated MI rats. The AST, ALT, CK, and GGT activities were appreciably decreased in serum and elevated in the cardiac tissues of the ponicidin-administered MI rats. Furthermore, the ponicidin improved the antioxidant levels, decreased the TNF-α and IL-6, and regulated the Na+, K+, and Ca2+ ion transports in the MI rats. The activities of Na+/K+, Mg2+, and Ca2+ ATPase enzymes were remarkably increased in the heart tissues by the ponicidin-treated MI rats. Ponicidin treatment also ameliorated the ISO-stimulated histological alterations in the heart tissue of the MI rats. Conclusion Ponicidin treatment appreciably improved the antioxidants, Na+/K+, Mg2+, and Ca2+ ATPase enzyme activities, decreased the inflammatory markers, and regulated the cardiac marker enzyme activities in the MI rats. Hence, it can be a talented therapeutic candidate in the future to treat MI.

Published: March 2023

Background: Acute agitation accounts for up to 2.6% of visits to the emergency department (ED). To date, a standard of care for the management of acute agitation has not been established. Few studies have evaluated antipsychotic and benzodiazepine combinations. Objective: The purpose of this study was to evaluate effectiveness and safety of combination therapy for acute agitation with intramuscular (IM) droperidol and midazolam (D+M) compared with IM haloperidol and lorazepam (H+L) in patients in the ED. Methods: This was a single-center, retrospective medical record review of patients presenting to a large, academic ED with acute agitation from July 2020 through October 2021. The primary outcome was percentage of patients requiring additional agitation medication within 60 minutes of combination administration. Secondary outcomes included average time to repeat dose administration and average number of repeat doses required before ED discharge. Results: A total of 306 patients were included for analysis: 102 in the D+M group and 204 in the H+L group. Repeat dose within 60 minutes occurred in 7 (6.9%) and 28 (13.8%) patients in the D+M and H+L groups, respectively ( P = 0.065). A total of 28.4% of D+M patients and 30.9% of H+L patients required any repeat dose during their ED visit. Time to repeat dose was 12 and 24 minutes in the D+M and H+L, respectively ( P = 0.22). The adverse event rate was 2.9% in each group. Conclusion and Relevance: IM D+M resulted in a lower rate of repeat doses of acute agitation medication compared with IM H+L, though this was not statistically significant. Both therapies were safe, and the adverse event rate was low.

Authors: Alzuhaily Hasan , Mohamad Seba , Alsalloum Lama , Al-Sayed Safaa 
Published: March 2023

Background: Adult-onset Still’s disease (AOSD) is a rare auto-inflammatory disorder with unknown etiology by which an infectious trigger is usually responsible for the onset of the disease. It is diagnosed by exclusion when certain clinical, biochemical, and radiological criteria are met after excluding all other potential causes. Besides, SARS‑CoV‑2 infection is increasingly being reported to have autoimmune complications. In the literature, 3 AOSD cases have been reported to be triggered by SARS‑CoV‑2 infection and here we report the fourth. Case presentation: A 24-year-old female doctor suffered from fever, sore throat, and mild cough a few days after a shift in the COVID-19 ward. A week later, she developed polyarthritis, salmon-colored rash, and high-grade fever, and the laboratory findings were indicating an inflammatory syndrome. COVID-19 IgM antibodies were positive indicating recent infection. After running a battery of tests, infectious, neoplastic, and rheumatic causes of these symptoms that persisted for about 50 days were excluded which led to a diagnosis of AOSD after fulfilling its criteria with subsequent treatment with methylprednisolone. Drastic improvement was achieved with no recurrence until the date of reporting. Conclusion: This case presents a new consequence of COVID-19 and adds to the emerging cumulative experiences with this disease. We encourage health care professionals to report such cases to further understand the nature of this infection and its possible outcomes.
Program Infrastructure the Key to Success: A Pilot Crosswalk Installation to Promote Walkability, Pedestrian Safety, and Physical Activity in the U.S. Virgin Islands
Authors: Ross Desiree Terese , Cash Haley L. , Orr John , Fenton Mark 
Published: March 2023

Background & Aims While physical inactivity can contribute to chronic diseases, regular activity like walking can help prevent them. In 2010, one in three adults in the U.S. Virgin Islands (USVI) was physically inactive, higher than most U.S. states and territories. There are few walkable destinations and sidewalks along streets in the USVI. Since community- and street-scale design features can influence walking, we convened a 3-day walkability institute in the USVI to (1) learn about physical activity and best practices for design and (2) develop public health infrastructure that supports implementation. Island teams were formed to develop and implement a territory-wide action plan, focused on passing a Complete Streets policy, and demonstration projects on the islands of St. Croix, St. John, and St. Thomas to advance and pass this policy. An example of the demonstration projects and their significance is the completed one in St. Croix, which is the focus of this article. Methods Island teams applied critical components of functioning program infrastructure as described in the Component Model of Infrastructure (CMI) such as engaged data, multilevel leadership, responsive plans and planning, and networked partnerships. We evaluated whether a crosswalk installation in St. Croix could alter driver and pedestrian behavior and create a safer environment for pedestrians. Observers recorded pedestrian crossing time, driver speed, and other behaviors before and after crosswalk installation. Results Pedestrians took significantly fewer average seconds to cross the street in the postdemonstration period (9.83) compared with predemonstration (13.4) ( p = .03). Average car speed declined between the predemonstration (24.3) and long-term demonstration periods (p < .01) and from the postdemonstration (24.7) to the long-term demonstration period (18.2) ( p < .01). A greater percentage of pedestrians used the crosswalk to cross the street between the postdemonstration (12.5%) and long-term demonstration periods (53.7%) (p < .01). Implications The demonstration project in St. Croix shows that improvements to built environment infrastructure can increase safety for pedestrians, thus improving walkability in the USVI. We discuss the importance of CMI elements observed in the success of the St. Croix demonstration and its effectiveness in promoting a Complete Streets policy and the lack of these elements on St. John hindering progress there. Public health practitioners can apply the CMI to future physical activity promotion projects in the USVI and other settings as having functioning program infrastructure helps overcome challenges including natural disasters and a global pandemic and can achieve progress toward sustained policy and systems change.

Objective: It is not well determined whether liver metastasis is a prognostic factor for survival of metastatic non-small cell lung cancer (NSCLC) patients who received immune checkpoint inhibitors (ICIs). We compared the efficacy of ICIs in patients with NSCLC with or without liver metastases, aiming to evaluate the impact of liver metastasis on survival of NSCLC. Methods: We systematically searched Pubmed, Embase, and the Cochrane library databases for randomized controlled trials (RCTs) on the efficacy of ICIs in the treatment of NSCLC patients with or without liver metastases. The duration of this search was from January 1, 2000 to June 1, 2022. The reviewers screened the literature, extracted data and conducted quality assessment, and used RevMan 5.4 software and Stata 14 to perform analyses. Results: A total of 17 RCTs were included, published from 2019 to 2022. For NSCLC patients with liver metastases, the risk of disease progression decreased by 36% (HR = 0.64; 95% CI: 0.55-0.75; P < .01) when treated with ICIs, and the death risk (HR = 0.82; 95% CI: 0.72-0.94; P < .01) was also reduced after ICIs treatment. For those without liver metastases, they had significantly improved PFS (HR = 0.56; 95% CI: 0.52-0.60; P < .01) and OS (HR = 0.73; 95% CI: 0.67-0.80; P < .01), compared to those of the control group. Subgroup analysis of OS in liver metastases patients suggested that OS benefit was associated with treatment strategy (for anti-PD-L1 plus chemotherapy versus chemotherapy, HR=1.04; 95% CI: 0.81-1.34; P =.75). Conclusion: For NSCLC patients with or without liver metastases, ICIs administration could improve both PFS and OS, especially for those without liver metastases. More RCTs are essential to verify these findings.
A cross-sectional study on alcohol and contraception use among sexually active women of childbearing age: Implications for preventing alcohol-exposed pregnancies
Authors: Parackal Sherly , Parackal Mathew , Akhtar Sumera Saeed 
Published: March 2023

Background: A high proportion of unwanted or unplanned pregnancies may be alcohol-exposed due to contraception failure or non-use. Nevertheless, data on contraception and alcohol use in the context of the risk of alcohol-exposed pregnancies are sparse. Objectives: To describe contraception use and alcohol consumption in sexually active non-pregnant women and investigate the factors associated with less effective contraception methods. Study Design: A cross-sectional national survey of women aged 18–35 years. Methods: Data from non-pregnant women who were sexually active ( n = 517) were analysed. Descriptive statistics were used to report demographics, consumption, and contraception measures. Logistic regression was used to investigate the factors associated with less effective contraception among drinkers. Results: The majority of participants were younger (46%), of NZ European ethnicity (78%), not in a permanent relationship (54%), with some or completed tertiary education (79%), employed (81%) and not users of the community services card (82%). Twenty-five percent of women were smokers, 94% consumed alcohol, and 72% binged at least ‘monthly or less’. Most women used the pill (56%), and 20% of drinking women were using a contraception method with a 10% or more annual failure rate after 1 year of use. Women who binged ‘weekly or more often’ had similar odds of using less effective contraception as women who ‘never’ binged ( p > 0.05). Younger Māori or Pacific women (odds ratio = 5.99; 95% confidence interval of odds 1.15 –31.2; p = 0.033) and women who had no tertiary education (odds ratio = 1.75; 95% confidence interval of odds 0.00 –3.06; p = 0.052) had higher odds of using less effective contraception. Conclusion: With 20% of women at risk of an alcohol-exposed pregnancy, public health measures to address alcohol consumption and the effective use of contraception are critical to reducing the risk for alcohol-exposed pregnancies in NZ.
