ABSTRACT

BACKGROUND: On a global scale, approximately 350 million are affected by hepatitis B, and 71 million by hepatitis C. People in custody face elevated risks for these infections. The prevalence and risk factors in Iranian prisons are insufficiently documented. The principal objective of this study was to ascertain the prevalence of hepatitis B and C, coupled with the identification of pertinent influencing factors, within the confines of Zahedan central prison, situated in the southeastern region of Iran.

METHODS: In 2019, we conducted an analytical cross-sectional study involving 407 people in custody, using stratified random sampling. To definitively diagnose hepatitis C virus (HCV) infection (P<0.05), a checklist developed by the researchers, along with enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) techniques, were employed.

RESULTS: This study comprised 406 participants (96.3% male) with a median age of 32 years (27-38). Approximately 62% were married, and a substantial proportion of the participants had low education levels (47%), unemployment (64%), and belonged to the Baloch ethnicity (64%). The overall prevalence of hepatitis C and B infections was 2.7% and 10.6%, respectively. Tattooing (adjusted odds ratio [AOR]: 2.07, 95% CI: 1.9-4.5) and marriage (AOR: 1.78, 95% CI: 1.05-3.04) were identified as risk factors for hepatitis B. Moreover, hepatitis C showed a statistically significant association with a family history of hepatitis B and C (AOR: 3.31, 95% CI: 3.93-24.64) and intravenous (IV) drug use (AOR: 7.01, 95% CI: 1.52-32.78) according to the multivariable logistic regression analysis.

CONCLUSION: The prevalence of hepatitis B and C was higher among people in custody in Zahedan central prison. Consequently, targeted interventions are vital to address and reduce viral hepatitis burden in custodial settings.

ABSTRACT

BACKGROUND: Given the significant occurrence of skin cancer in the Middle East and the existing research gap concerning its incidence and trends, this research aimed to study the epidemiology and trend changes of skin cancer in the Golestan province, Northeastern Iran.

METHODS: The Golestan Population-based Cancer Registry’s (GPCR’s) data bank was utilized to gather information on confirmed skin cancer cases in the province during 2005-2018. We used Poisson regression analysis for comparing incidence rates between groups. P values less than 0.05 were considered statistically significant.

RESULTS: Of 1690 patients (mean age: 62.05±15.83 years), most were male (60.1%) and resided in urban areas (61.5%). The age-standardized rate (ASR) of non-melanoma and melanoma skin cancer was 8.49 and 0.56 per 100000 persons-year, respectively. A notably higher ASR for non-melanoma skin cancer (NMSC) was observed in men (ASR: 10.60; 95% CI: 9.91-11.29) (P<0.01) and urban residents (ASR: 10.19; 95% CI: 9.52-10.82) (P<0.01). There was no significant difference in the ASR of melanoma skin cancer based on gender (P=0.24) and place of residence (P=0.48). The incidence trend of melanoma (estimated annual percent change [EAPC]: -3.28; 95% CI: -18.54 to 14.83) and NMSC (EAPC: 0.39; 95% CI: -3.99 to 4.97) did not differ significantly.

CONCLUSION: During the 14-year study period, the ASR of both types of skin cancer exhibited a consistent pattern, except for NMSC, which showed higher rates among men and urban residents. This should be taken into consideration when formulating preventive and control strategies in the study area.

ABSTRACT

BACKGROUND: Several studies have suggested a potential link between allergic rhinitis (AR) and gut microbiota. In response, we conducted a meta-analysis of Linkage Disequilibrium Score Regression (LDSC) and Mendelian randomization (MR) to detect their genetic associations.

METHODS: Summary statistics for 211 gut microbiota taxa were gathered from the MiBioGen study, while data for AR were sourced from the Pan-UKB, the FinnGen, and the Genetic Epidemiology Research on Aging (GERA). The genetic correlation between gut microbiota and AR was assessed using LDSC. The principal estimate of causality was determined using the Inverse-Variance Weighted (IVW) method. To assess the robustness of these findings, sensitivity analyses were conducted employing methods such as the weighted median, MR-Egger, and MR-PRESSO. The summary effect estimates of LDSC, forward MR and reverse MR were combined using meta-analysis for AR from different data resources.

RESULTS: Our study indicated a significant genetic correlation between genus Sellimonas (Rg = -0.64, p = 3.64 × 10^-5, Adjust_P = 3.64 × 10^-5) and AR, and a suggestive genetic correlation between seven bacterial taxa and AR. Moreover, the forward MR analysis identified genus Gordonibacter, genus Coprococcus2, genus LachnospiraceaeUCG010, genus Methanobrevibacter, and family Victivallaceae as being suggestively associated with an increased risk of AR. The reverse MR analysis indicated that AR was suggestively linked to an increased risk for genus Coprococcus2 and genus RuminococcaceaeUCG011.

CONCLUSION: Our findings indicate a causal relationship between specific gut microbiomes and AR. This enhances our understanding of the gut microbiota’s contribution to the pathophysiology of AR and lays the groundwork for innovative approaches and theoretical models for future prevention and treatment strategies in this patient population.

ABSTRACT

AIM: Athletic pre-season testing can establish functional baseline for comparison following concussion. Whether impacts of future concussions may be foretold by such testing is little known.

MATERIALS & METHODS: Two sets of models for a significant burden of concussion were generated: a traditional approach using a series of logistic regressions, and a penalized regression approach using elastic net.

RESULTS: 3091 youth and adult athletes were baseline-assessed. 90 subsequently experienced concussion and 35 were still experiencing a significant burden of concussion when tested within two weeks. Both models associated prior history of head injury and visual attention-related metrics with a significant burden of concussion.

CONCLUSION: Pre-season testing of visual attention may identify athletes who are at risk for significant sports-related concussion.

ABSTRACT

BACKGROUND: Neuroinflammation pathways have been associated with the development of major depressive disorders (MDD). The anti-inflammatory characteristics of statins have been demonstrated to have significance in the pathophysiology of depression.

AIM: To investigate the mechanistic pathways of high dose atorvastatin in MDD.

PATIENTS AND METHODS: This trial included 60 patients with MDD who met the eligibility requirements. Two groups of patients (n = 30) were recruited by selecting patients from the Psychiatry Department. Group 1 received 20 mg of fluoxetine plus a placebo once daily. Group 2 received fluoxetine and atorvastatin (80 mg) once daily. All patients were assessed by a psychiatrist using the Hamilton Depression Rating Scale (HDRS). A HDRS score of ≤7 indicates remission or partial remission [HDRS<17 and>7]. Response was defined as ≥ 50% drop in the HDRS score. The serum concentrations of nucleotide-binding domain, leucine-rich-containing family, pyrin domain-containing-3 (NLRP-3), interleukin-6 (IL-6), adenosine monophosphate activated protein kinase (AMPK), and signal transducer and activator of transcription factor-3 (STAT-3) were measured.

RESULTS: The atorvastatin group showed a significant reduction in the levels of all measured markers along with a statistical increase in the levels of AMPK when compared to the fluoxetine group. The atorvastatin group displayed a significant decrease in HDRS when compared to its baseline and the fluoxetine group. The response rate and partial remission were higher in the atorvastatin group than fluoxetine (p = 0.03, and p = 0.005), respectively.

CONCLUSION: These results imply that atorvastatin at high doses may be a promising adjuvant therapy for MDD patients by altering the signaling pathways for AMPK/NLRP3 and IL-6/STAT-3.

ABSTRACT

OBJECTIVE: This meta-analysis aimed to determine the efficacy of curcumin in preventing liver fibrosis in animal models.

METHODS: A systematic search was conducted on studies published from establishment to November 2023 in PubMed, Web of Science, Embase, Cochrane Library, and other databases. The methodological quality was assessed using Sycle’s RoB tool. An analysis of sensitivity and subgroups were performed when high heterogeneity was observed. A funnel plot was used to assess publication bias.

RESULTS: This meta-analysis included 24 studies involving 440 animals with methodological quality scores ranging from 4 to 6. The results demonstrated that curcumin treatment significantly improved Aspartate aminotransferase (AST) [standard mean difference (SMD) = -3.90, 95% confidence interval (CI) (-4.96, -2.83), p < 0.01, I² = 85.9%], Alanine aminotransferase (ALT)[SMD = – 4.40, 95% CI (-5.40, -3.40), p < 0.01, I² = 81.2%]. Sensitivity analysis of AST and ALT confirmed the stability and reliability of the results obtained. However, the funnel plot exhibited asymmetry. Subgroup analysis based on species and animal models revealed statistically significant differences among subgroups. Furthermore, curcumin therapy improved fibrosis degree, oxidative stress level, inflammation level, and liver synthesis function in animal models of liver fibrosis.

CONCLUSION: Curcumin intervention not only mitigates liver fibrosis but also enhances liver function, while concurrently modulating inflammatory responses and antioxidant capacity in animal models. This result provided a strong basis for further large-scale animal studies as well as clinical trials in humans in the future.

ABSTRACT

China, one of the most populous countries in the world, has suffered the highest number of natural disaster-related deaths from fire. On local scales, the main causes of urban fires are anthropogenic in nature. Yet, on regional to national scales, little is known about the indicators of large-scale co-varying urban fire activity in China. Here, we present the China Fire History Atlas (CFHA), which is based on 19 947 documentary records and represents fires in urban areas of China over the twentieth century (1901-1994). We found that temperature variability is a key indicator of urban fire activity in China, with warmer temperatures being correlated with more urban fires, and that this fire-temperature relationship is seasonally and regionally explicit. In the early twentieth century, however, the fire-temperature relationship was overruled by war-related fires in large urban areas. We further used the fire-temperature relationship and multiple emissions scenarios to project fire activity across China into the twenty-first century. Our projections show a distinct increase in future urban fire activity and fire-related economic loss. Our findings provide insights into fire-climate relationships in China for densely-populated areas and on policy-relevant time scales and they contribute spatial coverage to efforts to improve global fire models.

ABSTRACT

This pilot study examined differences in wait times for oncology patients who presented to the emergency department, with or without a Fast Pass, for febrile neutropenia (FN). Inadequate circulating neutrophils create a health risk for FN patients. An increased number of patients are receiving chemotherapy in an outpatient setting and may experience delays when seeking treatment in the emergency department. These delays in treatment may be due to overcrowding, patients who require life-saving medical interventions, and inconsistencies in recognizing febrile neutropenia, where fever may be the only presenting sign. The purpose of this study was to measure the impact on wait times, increasing possible risk of bacterial or viral exposure in the emergency department waiting room, for patients with a potential diagnosis of FN who presented their “Fast Pass” from the hospital cancer center’s program upon arrival. Electronic medical records were reviewed over a period of 21 months, comparing wait times in the ED for oncology patients with potential FN before and after implementation of the Fast Pass program at an urban medical center in Hawai’i. Of the 1300 oncology patient chart reviews conducted, 6 patients met the study-defined inclusion criteria pre-Fast Pass and 10 met the study-defined inclusion criteria post-Fast Pass. Influence of the use of a Fast Pass on patient wait times was tested using a multivariate regression adjusted for ED patient volume. There were no differences in overall wait times pre- and post-Fast Pass.

ABSTRACT

Hawai’i experiences some of the highest rates of houselessness per capita in the country. COVID-19 has exacerbated these disparities and made it difficult for these individuals to seek medical care. Hawai’i’s Houseless Outreach in Medical Education (HOME) clinic is the largest student run free clinic in the state, which provides medical services to this patient population. This article reports the demographics, medical needs, and services provided to patients of Hawai’i’s HOME clinic during the era of COVID-19. From September 2020 to 2021, the HOME clinic saw 1198 unique visits with 526 distinct patients. The most common chief complaints included wound care (42.4%), pain (26.9%), and skin complaints (15.7%). A large portion of the population suffered from comorbidities including elevated blood pressure (66%), a formal reported history of hypertension (30.6%), diabetes (11.6%), and psychiatric concerns including schizophrenia (5.2%) and generalized anxiety (5.1%). Additionally, a large portion of patients (57.2%) were substance users including 17.8% of patients endorsing use of alcohol, 48.5% tobacco and 12.5% marijuana. The most common services provided were dispensation of medication (58.7%), wound cleaning/dressing changes (30.7%), and alcohol or other drug cessation counseling (25.2%). This study emphasizes that the houseless are a diverse population with complex, evolving medical needs and a high prevalence of chronic diseases and comorbidities.

ABSTRACT

The global COVID-19 outbreak severely hampered the growth of the global economy, prompting the implementation of the strictest prevention policies in China. Establishing a significant relationship between changes in nighttime light and COVID-19 lockdowns from a geospatial perspective is essential. In light of nighttime light remote sensing, we evaluated the spatiotemporal dynamic effects of COVID-19 city lockdowns on human activity intensity in the Zhengzhou region. Prior to the COVID-19 outbreak, nighttime light in the Zhengzhou region maintained a significant growth trend, even under regular control measures. However, following the October 2022 COVID-19 lockdown, nighttime light experienced a substantial decrease. In the central area of Zhengzhou, nighttime light decreased by at least 18% compared to pre-lockdown levels, while in the sub-center, the decrease was around 14%. The areas where nighttime light decreased the most in the central region were primarily within a 15 km radius, while in the sub-center, the decrease was concentrated within a 5 km radius. These changes in both statistical data and nighttime light underscored the significant impact of the COVID-19 lockdown on economic activities in the Zhengzhou region.
