Perceived efficacy of existing waterpipe tobacco warning labels versus novel enhanced generic and waterpipe-specific sets

Introduction Since 2008, Egypt has four existing generic bi-annually rotating warning labels (WLs) on 50% of the waterpipe tobacco packs (WTPs). The Ministry of Health Tobacco Control Unit proposed increasing WL size to 80%, removing colours and flavour imagery from WTPs, and plain packaging to help curb the rising epidemic of waterpipe tobacco smoking. Therefore, we measured the perceived efficacy of existing against novel enhanced (generic and waterpipe-specific) WTP WLs and the associated factors among Egyptian waterpipe smokers and nonsmokers. Methods A purposive quota sample of 2014 adults was surveyed in two rounds using face interviews. At each round, participants were randomly shown one of four existing WLs, then one of four novel WLs. Participants rated the perceived efficacy of existing and novel WLs regarding the salience, depth of processing, affective reactions, credibility, relevance, perceived harm and perceived behavioural control. Data were analysed using Generalized Estimating Equations. Results Participants rated novel WTP WLs with higher mean perceived efficacy scores than existing WLs for all measures, although both sets collectively scored modestly (59.7; 95% CI: 58.9–60.5 vs 53.0; 95% CI: 52.1–54.0, respectively; p<0.001). Relative to the existing WTP WLs, novel WLs were particularly able to induce higher salience, affective reactions, and depth of processing. Relative to the generic novel WTP WLs, waterpipe-specific WLs induced higher relevance, perceived harm, and affective reactions. Nonsmokers scored higher than waterpipe tobacco smokers, specifically for perceived behavioral control (65.0±32.5 vs 43.6±19.8, respectively; p<0.001). WTP WLs featuring proximal risks, such as dental effects (β = 9.70; 95% CI: 7.00–12.40), fetal harm (β = 9.42; 95% CI: 6.75–12.10), or toxic contents (β = 9.14; 95% CI: 6.58–11.70) were strongly associated with participants’ perceived efficacy scores. Among other independent factors, rural residence (β = 24.09; 95% CI: 22.21–25.97), being a nonsmoker (β = 10.51; 95% CI: 8.92–12.10), survey round 2 (β = 6.96, 95% CI: 5.73–8.19), the novel WTP WL set (β = 6.68; 95% CI: 6.19–7.17), and having higher education (β = 6.31; 95% CI: 4.34–8.27) were highly associated with participants’ perceived efficacy scores. Conclusions Waterpipe-specific WLs on plain WTPs that feature proximal risks and address different population subgroups need to be developed in conjunction with awareness raising campaigns on WTS harms to reinforce the credibility of WTP WLs. Our findings suggest the proposed WTP WL enhancements by the Tobacco Control Unit may support a more effective WTP labelling policy within a comprehensive waterpipe-specific tobacco control framework.
Co-occurring mental and behavioral health conditions among collegiate recovery program members

Abstract Objective: This study describes the mental and behavioral health histories and treatment utilization among students enrolled in Collegiate Recovery Programs (CRPs), college-based supports for students who are in recovery from substance use or other comorbid disorders. Participants: Participants were 861 college students enrolled in five CRPs across the United States (44% female, 89% white, 91% undergraduate). Methods: De-identified student data, collected from 2019–2020, were harmonized and descriptively analyzed. Results: A majority of CRP students reported mental health and substance use treatment histories. Approximately one-third reported a history of eating disorders or other compulsive behaviors (46%) and 69% reported histories of mental health concerns. Results indicated a complex history of mental health and substance use recovery needs among students. Conclusions: Students attending CRPs reported a wide range of mental and behavioral health concerns in addition to substance use disorders, highlighting the need for continued support for these students’ recovery and well-being at higher education institutions.
Human Papilloma Virus Distribution Across the African Diaspora

PURPOSE Understanding the distribution of human papilloma virus (HPV) subtypes in limited-resource settings is imperative for cancer prevention strategies in these regions. The objective of our study is to compare the prevalence of cervical HPV genotypes in women across the African diaspora. METHODS This study was approved by the African Caribbean Consortium (AC3). Six member institutions (Benin, Ethiopia, The Bahamas, Tobago, Curacao, and Jamaica) provided independently collected HPV data. Prevalence comparisons across for each nation were performed followed by an assessment of anticipated 9-valent vaccine coverage. Chi-square or Fisher's exact tests were used with significance at P < . 05. RESULTS One thousand three hundred fifty high-risk (HR) and 584 low-risk (LR) HPV subtypes were identified in the entire cohort. The most common HR HPV subtype was HPV 16 (17.9%) of infections. The distribution of HR and LR subtypes varied by country. The proportion of HR-HPV subtypes covered by the current 9-valent vaccine was lower in African countries compared with the Caribbean countries (47.9% v 67.9%; P < .01). No significant difference was seen for LR subtypes (8.1% African continent v 5.2% Caribbean; P = .20). Marked variation in the proportion of infections covered by the 9-valent vaccine persisted in individual countries. CONCLUSION Significant variations in HPV prevalence were identified among African and Afro-Caribbean women. A large number of women in these regions are potentially uncovered by current vaccination formulation, particularly low-risk HPV infections.
The burden of scrub typhus in India: A systematic review

Background Scrub typhus, a vector-borne zoonotic infection caused by the bacteria Orientia tsutsugamushi, is one of the most common and clinically important rickettsial infections worldwide. An estimated one million cases occur annually with a high case fatality rate. Although scrub typhus is a major public health threat in India, the burden and distribution remains unclear. We aimed to estimate the burden of scrub typhus in India. Methodology We performed a systematic review of published literature on scrub typhus from India to extract information on epidemiology, morbidity, and mortality. Important databases were searched using keywords and appropriate combinations. We identified observational, interventional, and population-based studies and extracted the data to evaluate the number of cases diagnosed using serology or PCR and the number of deaths due to scrub typhus. We conducted a systematic narrative synthesis to summarize included studies. Principal findings In the last decade, there were 18,781 confirmed scrub typhus cases reported in 138 hospital-based studies and two community-based studies. IgM ELISA was used in 122 studies to confirm the cases in majority (89%). The proportion of scrub typhus among acute undifferentiated febrile illness (AUFI) studies was 25.3%, and community seroprevalence was 34.2%. Ninety studies had data published on multiple organ involvement out of which 17.4% of cases had multiple organ dysfunction syndromes, 20.4% patients required ICU admission, and 19.1% needed ventilation. The overall case-fatality rate was 6.3%, and the mortality among those with multi-organ dysfunction syndrome was as high as 38.9%. Conclusion/significance Scrub typhus, a common acute febrile illness in India causing severe morbidity, accounts for a large number of deaths. The burden of the disease has been underappreciated. Early diagnosis and prompt treatment can significantly reduce complications and mortality. Establishing good surveillance and instituting appropriate control measures are urgently needed.
Pediatric prolonged-release melatonin for insomnia in children and adolescents with autism spectrum disorders

ABSTRACT Introduction: Insomnia is common among children and adolescents with Autism spectrum disorder (ASD). The first drug licensed for insomnia in this population, a pediatric-appropriate prolonged-release melatonin (PedPRM) formulation is described. Areas covered: Literature search on PedPRM efficacy and safety profile in clinical trials, and a proposed decision-making algorithm to optimize outcome in the treatment of insomnia in children and adolescents with ASD. Expert opinion: PedPRM treatment effectively improves sleep onset, duration and consolidation, and daytime externalizing behaviors in children and adolescents with ASD and subsequently caregivers’ quality of life and satisfaction with their children’s sleep. The coated, odorless and taste-free mini-tablets are well-accepted in this population who often have sensory hypersensitivity and problems swallowing standard tablet preparations. The most frequent long-term treatment-related adverse events were fatigue (6.3%), somnolence (6.3%), and mood swings (4.2%) with no evidence of delay in height, BMI, or pubertal development, or withdrawal effects. The starting dose is 2 mg once daily independent of age or weight, escalated to 5–10 mg/day if predefined treatment success criteria are unmet. Slow melatonin metabolizers (~10% of children), may require lower doses. Given its long-term efficacy, safety and acceptance, PedPRM may ameliorate long-term consequences of insomnia in this population.
Fatty acid mobilization from adipose tissue is mediated by CD36 posttranslational modifications and intracellular trafficking

The mechanism controlling long-chain fatty acid (LCFA) mobilization from adipose tissue is not well understood. Here, we investigated how the LCFA transporter CD36 regulates this process. By using tissue-specific KO mouse models, we showed that CD36 in adipocytes and endothelial cells mediated both LCFA deposition into and release from adipose tissue. We demonstrated the role of adipocytic and endothelial CD36 in promoting tumor growth and chemoresistance conferred by adipose tissue–derived LCFAs. We showed that dynamic cysteine S-acylation of CD36 in adipocytes, endothelial cells, and cancer cells mediated intercellular LCFA transport. We demonstrated that lipolysis induction in adipocytes triggered CD36 deacylation and deglycosylation, as well as its dissociation from interacting proteins, prohibitin-1 (PHB) and annexin 2 (ANX2). Our data indicate that lipolysis triggers caveolar endocytosis and translocation of CD36 from the cell membrane to lipid droplets. This study suggests a mechanism for both outside-in and inside-out cellular LCFA transport regulated by CD36 S-acylation and its interactions with PHB and ANX2.
3D Finite Element Modeling of Blast Wave Transmission From the External Ear to a Spiral Cochlea.

Blast-induced injuries affect the health of veterans, in which the auditory system is often damaged, and blast-induced auditory damage to the cochlea is difficult to quantify. A recent study modeled blast overpressure (BOP) transmission throughout the ear utilizing a straight, two-chambered cochlea, but the spiral cochlea's response to blast exposure has yet to be investigated. In this study, we utilized a human ear finite element (FE) model with a spiraled, two-chambered cochlea to simulate the response of the anatomical structural cochlea to BOP exposure. The FE model included an ear canal, middle ear, and two and half turns of two-chambered cochlea and simulated a BOP from the ear canal entrance to the spiral cochlea in a transient analysis utilizing fluid-structure interfaces. The model's middle ear was validated with experimental pressure measurements from the outer and middle ear of human temporal bones. The results showed high stapes footplate displacements up to 28. 5µm resulting in high intracochlear pressures and basilar membrane (BM) displacements up to 43. 2µm from a BOP input of 30.7kPa. The cochlea's spiral shape caused asymmetric pressure distributions as high as 4kPa across the cochlea's width and higher BM transverse motion than that observed in a similar straight cochlea model. The developed spiral cochlea model provides an advancement from the straight cochlea model to increase the understanding of cochlear mechanics during blast and progresses towards a model able to predict potential hearing loss after blast.
Prion Dissemination through the Environment and Medical Practices: Facts and Risks for Human Health

Prion diseases are a group of fatal, infectious neurodegenerative disorders affecting various species of mammals, including humans. The infectious agent in these diseases, termed prion, is composed exclusively of a misfolded protein that can spread and multiply in the absence of genetic materials. SUMMARY Prion diseases are a group of fatal, infectious neurodegenerative disorders affecting various species of mammals, including humans. The infectious agent in these diseases, termed prion, is composed exclusively of a misfolded protein that can spread and multiply in the absence of genetic materials. In this article, we provide an overview of the mechanisms of prion replication, interindividual transmission, and dissemination in communities. In particular, we review the potential role of the natural environment in prion transmission, including the mechanisms and pathways for prion entry and accumulation in the environment as well as its roles in prion mutation, adaptation, evolution, and transmission. We also discuss the transmission of prion diseases through medical practices, scientific research, and use of biological products. Detailed knowledge of these aspects is crucial to limit the spreading of existing prion diseases as well as to prevent the emergence of new diseases with possible catastrophic consequences for public health.
Differences in Retinal and Choroidal Vasculature and Perfusion Related to Axial Length in Pediatric Anisomyopes

Purpose The purpose of this study was to evaluate the interocular differences in choroidal vasculature, choriocapillaris perfusion, and retinal microvascular network, and to explore their associations with interocular asymmetry in axial lengths (ALs) in children with anisomyopia. Methods Refractive error, AL, and other biometric parameters were measured in 70 children with anisomyopia. Using optical coherence tomography (OCT) and OCT-angiography, we measured the submacular choroidal thickness (ChT), total choroidal area (TCA), luminal area (LA), stromal area (SA), choroidal vascularity index (CVI), choriocapillaris flow deficit (CcFD), retinal vessel density (VD), and foveal avascular zone (FAZ) area. Results The mean interocular differences in spherical equivalent refraction and AL were −2.26 ± 0.94 diopters and 0.95 ± 0.46 mm, respectively. Submacular ChT, TCA, LA, SA, and CVI were all significantly lower in the more myopic (longer AL) eyes than in the less myopic (shorter AL) fellow eyes. In eyes with longer ALs, both the CcFD and FAZ areas were significantly greater, whereas the superficial and deep retinal VDs were significantly less. After adjusting for corneal power and intraocular pressure, interocular differences in LA (β = −0.774), SA (β = −0.991), and CcFD (β = 0.040) were significantly associated with interocular asymmetry in AL (all P < 0.05). Conclusions In pediatric anisomyopes, eyes with longer ALs tended to have lower choroidal vascularity and choriocapillaris perfusion than the contralateral eyes with shorter ALs. Longitudinal investigations would be useful follow-ups to test for a causal role of choroidal circulation in human myopia.
Prevalence of urogenital and intestinal schistosomiasis among school children in South-west Nigeria

Background The risk of co-infection with Schistosoma haematobium and S. mansoni and the potential harmful effect on morbidity and control is enhanced by the overlapping distribution of both species in sub-Saharan Africa. Despite the reported high endemicity of both species in Nigeria, studies on the spread and effect of their mixed infection are limited. Therefore, a cross-sectional survey was conducted among school children in two communities in South-west Nigeria to investigate the prevalence of mixed human schistosome infection, intensity, and possible ectopic egg elimination. Methods Urine and stool samples were collected from consenting school children in Ilie and Ore communities of Osun State, Nigeria. Schistosoma haematobium eggs were detected in urine using the urine filtration technique, while S. mansoni eggs were detected in stool using the Kato–Katz thick smear technique. Results The study enrolled 466 primary and secondary school children (211; 45.3% males vs. 255; 54.7% females; mean age 11.6 ± 3.16 years). The overall prevalence of schistosomiasis was 40% (185/466), with 19% (89/466) recording single S. haematobium infection while 9% (41/465) had a single S. mansoni infection. The geometric mean egg count for S. haematobium was 189.4 egg/10ml urine; 95% CI: range 115.9–262.9, while for S. mansoni, it was 115.7 epg; 95% CI: range 78.4–152.9. The prevalence of ectopic S mansoni (S. mansoni eggs in urine) was 4.7%, while no ectopic S. haematobium (S. haematobium eggs in stool) was recorded. Mixed infection of S. haematobium/S. mansoni had a prevalence of 9.5% (44/466). More females (54.5%) presented with S. haematobium/S. mansoni co-infection. For both parasites, males had higher infection intensity, with a significant difference observed with S. haematobium (p = 0.0004). Hematuria was significant in individuals with single S. haematobium infection (p = 0.002), mixed ectopic S. haematobium/S. mansoni (p = 0.009) and mixed S. haematobium/S. mansoni/ectopic S. mansoni (p = 0.0003). Conclusions These findings suggest the probability of interspecific interactions between S. haematobium and S. mansoni. Scaling up of mass administration of praziquantel and control measures in the study areas is highly desirable.
Clinical Presentations, Management and Outcomes of Rhino-Orbital-Cerebral Mucormycosis (ROCM) Following COVID-19: A Multi-Centric Study

Purpose: To report clinical presentations and factors affecting outcomes in rhino-orbital-cerebral mucormycosis following COVID-19. Methods: Retrospective multi-centric interventional case series of 58 eyes with rhino-orbital-cerebral mucormycosis. Demography, clinical parameters and management outcomes were noted. Factors affecting outcome and mortality were analyzed. Outcome was defined as favorable when complete resolution or stabilization without further progression of the infection was noted at last visit. Results: Mean age was 55 ± 11 years (median 56). The mean HbA1c value was 10.44 ± 2.84 mg% (median 10.5). The duration between the diagnosis of COVID-19 and rhino-orbital-cerebral mucormycosis was 16 ± 21 days (median: 8 days). Thirty-six eyes (62%) had no vision at presentation. Imaging revealed paranasal sinus involvement (100%), orbital apex involvement (41%), cavernous sinus involvement (30%), and central nervous system (CNS) involvement (33%). All the patients were treated with systemic Liposomal amphotericin-B and sinus debridement. Twenty-two eyes (38%) underwent exenteration. One eye underwent transcutaneous retrobulbar amphotericin-B. The mean follow-up duration was 5.62 ± 0.78 months (median 6). Favorable outcome was seen in 35 (60%) cases. Presence of uncontrolled diabetes (p = 0.001), orbital apex involvement (p = 0.04), CNS involvement (p = 0.04), and history of steroid use (p < 0.0001) resulted in unfavorable outcome. CNS involvement was the only factor predicting mortality (p = 0.03). Mortality was seen in 20 (34%) patients. Conclusion: Over a third of patients with rhino-orbital-cerebral mucormycosis following COVID-19 have an unfavorable clinical outcome. Uncontrolled diabetes mellitus at presentation, involvement of the orbital apex, CNS, and the usage of steroids were associated with poorer outcomes. CNS involvement was a factor determining mortality. In 58 patients with rhino-orbital-cerebral mucormycosis post-COVID-19, favorable outcome was seen in 35 (60%) cases. Uncontrolled diabetes, orbital apex involvement, cavernous sinus involvement, and use of steroids for COVID-19, resulted in unfavorable outcome.
Imaging Reveals Importance of Shape and Flexibility for Glomerular Filtration of Biologics

Advances in antibody engineering have enabled the construction of novel molecular formats in diverse shapes and sizes, providing new opportunities for cancer immunotherapeutic drug discovery while also revealing limitations in knowledge of structure–activity relationships. The current understanding of renal filtration originates largely from data reported for dextrans, IgG, albumin, and selected globular proteins. For a one-armed IgG-based T-cell imaging agent, we observed higher renal signal than typically observed for bivalent IgGs, prompting us to explore the factors governing renal filtration of biologics. We constructed a small representative library of IgG-like formats with varied shapes and hinge flexibilities falling broadly into two categories: branched molecules including bivalent IgG and (scFv)2Fc, and nonbranched molecules including one-armed IgG, one-armed IgG with stacked Fab, and one-armed IgG with a rigid IgA2 hinge. Transmission electron microscopy revealed Y-shaped structures for the branched molecules and pseudo-linear structures for the nonbranched molecules. Single-photon emission CT imaging, autoradiography, and tissue harvest studies demonstrated higher renal uptake and catabolism for nonbranched molecules relative to branched molecules. Among the nonbranched molecules, the one-armed IgG with rigid IgA2 hinge molecule demonstrated higher kidney uptake and decreased systemic exposure relative to molecules with a more flexible hinge. Our results show that differences in shape and hinge flexibility drive the increased glomerular filtration of one-armed relative to bivalent antibodies and highlight the practical advantages of using imaging to assess renal filtration properties. These findings are particularly relevant for T-cell–dependent bispecific molecules, many of which have nonstandard antibody structures.

Clathriketal, a new tricyclic spiroketal compound from marine sponge Clathria prolifera attenuates serine exopeptidase dipeptidyl peptidase-IV

Abstract An undescribed tricyclic spiroketal compound clathriketal was purified from the solvent extract of the Microcionidae sponge Clathria prolifera, and was characterised as 7-(hydroxymethyl)-13-methoxy-3,11-dimethyl-4-oxo-octahydrospiro[chromene-9,13-pyran]-11-yl propionate by spectroscopic experiments. Clathriketal exhibited significant anti-hyperglycemic property by attenuating serine protease dipeptidyl peptidase-IV (IC50 0.37 mM), and its activity was comparable with the standard diprotin A (IC50 0.31 mM). The spiroketal also exhibited significant inhibitory potentials against carbolytic enzymes α-glucosidase (IC50 0.43 mM) and α-amylase (IC50 0.41 mM). Superior antioxidant properties of clathriketal against the oxidants, 2, 2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid and 2, 2-diphenyl-1-picrylhydrazyl (IC50 ∼1.2 mM) also reinforced its promising anti-hyperglycemic activity. Considerably greater topological surface area (91.29) coupled with lesser steric parameters of clathriketal, as elucidated from the structure-activity relationship analyses could further ascribe the improved ligand-receptor interactions resulting in its prospective anti-hyperglycemic activity. Molecular docking analysis of clathriketal with dipeptidyl peptidase-IV recorded lesser binding energy (–9.63 kcal/mol), which further corroborated its prospective antihyperglycemic activity.
