HIV Disclosure Practices to Family Among Mexican and Puerto Rican Sexual Minority Men with HIV in the Continental USA: Intersections of Sexual Orientation and HIV Stigma

ABSTRACT Disclosing a seropositive HIV status still is a complex process of assessing the risks, benefits, and potential personal and interpersonal outcomes associated with disclosure, such as stigma, rejection, or emotional support. We examined HIV disclosure practices to family and intersectional stigma related to HIV and sexual orientation among Latino sexual minority men (LSMM) of Mexican and Puerto Rican origin with HIV in the continental USA. Guided by Framework Analysis, we present data from 54 interviews with 33 LSMM participants in HIV care engagement interventions, and 21 project staff implementing the interventions. LSMM disclosed their HIV status to family seeking support. They applied stigma management techniques to manage the information communicated to family about their HIV status, including selective disclosure to some family members, conveying strategic information about the significance of having HIV, non-disclosure, or partial disclosure, silence and deceptions. LSMM HIV disclosure practices to family encompassed appraisals of intersectional stigma related to their sexual orientation and HIV, assessing the potential outcomes of disclosure, and the preservation of family ties.
Cancer Incidence in the Kurdistan Region of Iraq: Results of a Seven-Year Cancer Registration in Erbil and Duhok Governorates

Introduction: There are limited published data regarding the recent incidence trends of cancer in Iraqi Kurdistan. Methods: The present study assessed the epidemiological estimates of cancer incidence, as well providing a projection of future cancer trends in the upcoming decade by analysing the population-based cancer registry between 2013 and 2019, in both the Erbil and Duhok governorates. A retrospective analysis was performed on data retrieved from the Medical Statistics Department at the Ministry of Health, Kurdistan Regional Government (KRG). Results: The total number of female cancer patients was higher in both governorates, and the total incidence of patients with cancer increased by over 2x between 2013 and 2019 in Erbil and Duhok, from 73 to 174 patients/100,000 individuals for women, and 36 to 85 patients/100,000 individuals for men. Analysis indicated that the percentage of patients with cancer is projected to increase by >2x in the current decade, from 3,457 cases to 4,547 and 4,449 cases in the Erbil governorate; and from 1,365 to 2,633 and 2,737 cases in 2028 based on LSTM and bi-LTSM analysis in the Duhok governorate. Lung cancer (LC) and female breast cancer (BC) were the most prominent types of cancers diagnosed since 2013 in both the Erbil and Duhok governorates. Conclusion: The striking pattern of trends for both present and future cancer incidence rates require urgent solutions and comprehensive efforts to control risk factors that promote the increasing incidence of cancer in these two KRG governorates.
Tracking Strain‐Specific Morphogenesis and Angiogenesis of Murine Calvaria with Large‐Scale Optoacoustic and Ultrasound Microscopy

Skull bone development is a dynamic and well‐coordinated process playing a key role in maturation and maintenance of the bone marrow (BM), fracture healing, and progression of diseases such as osteoarthritis or osteoporosis. At present, dynamic transformation of the growing bone (osteogenesis) as well as its vascularization (angiogenesis) remain largely unexplored due to the lack of suitable in vivo imaging techniques capable of noninvasive visualization of the whole developing calvaria at capillary‐level resolution. We present a longitudinal study on skull bone development using ultrasound‐aided large‐scale optoacoustic microscopy (U‐LSOM). Skull bone morphogenesis and microvascular growth patterns were monitored in three common mouse strains (C57BL/6J, CD‐1, and Athymic Nude‐Foxn1nu) at the whole‐calvaria scale over a 3‐month period. Strain‐specific differences in skull development were revealed by quantitative analysis of bone and vessel parameters, indicating the coupling between angiogenesis and osteogenesis during skull bone growth in a minimally invasive and label‐free manner. The method further enabled identifying BM‐specific sinusoidal vessels, and superficial skull vessels penetrating into BM compartments. Our approach furnishes a new high‐throughput longitudinal in vivo imaging platform to study morphological and vascular skull alterations in health and disease, shedding light on the critical links between blood vessel formation, skull growth, and regeneration. © 2022 The Authors.

The Clinical Characteristics, Risk Classification System, and Web-Based Nomogram for Primary Spinal Ewing Sarcoma: A Large Population-Based Cohort Study

Background The goal of this study was to determine the clinical characteristics of patients with primary spinal Ewing sarcoma (PSES) and to create a prognostic nomogram. Methods Clinical information related to patients diagnosed with PSES between 2004 and 2015 was extracted from the Surveillance, Epidemiology, and End Results (SEER) database. Independent prognostic factors were identified using univariate and multivariate Cox analyses to construct nomograms predicting overall survival in patients with PSES. Calibration curves and receiver operating characteristic curves were used to assess the model’s prediction accuracy, while decision curve analysis was used to assess the model’s clinical utility. Results The overall number of 314 patients with PSES were screened from the SEER database between 2004 and 2015. Race, chemotherapy, age, and disease stage were found to be independent predictive factors for overall survival in both univariate and multivariate Cox analyses. The training and validation cohorts’ calibration curves, receiver operating characteristic curves, and decision curve analysis showed that the nomogram has strong discrimination and clinical value. Furthermore, a new risk classification system has been constructed that can divide all patients into 2 risk groups. Conclusions Based on a broad population, the research demonstrates statistical evidence for the clinical features and prognostic variables of patients with PSES. The constructed prognostic nomogram provides a more precise prediction of prognosis for PSES patients.
Incidence of Pediatric Multiple Sclerosis in Iran within 2000-2019

Objectives Due to a lack of data on pediatric multiple sclerosis (MS) epidemiology in Iran, this study aimed to determine the incidence rate of pediatric MS in Iran. Materials & Methods All the data of the patients with MS registered in the Ministry of Health and Medical Education of Iran for 20 years were collected in this study; those born in 1982 and diagnosed with the disease and treated since 2000 were included in this study. Therefor The collected variables were patients’ age at the time of diagnosis, gender, year of diagnosis, urban or rural residency, and province of residence. Additionally, age-specific incidence rates per 100,000 of the population were calculated. Results This study was performed on 4544 cases of pediatric MS within 2000-2019, of which 997 patients (21.9%) were male. The mean age of the patients with MS at the time of diagnosis was 14.3±4.6 years, and 4414 children (97.1%) lived in urban areas. The incidence rate of pediatric MS in Iran during 20 years increased from 0.26 per 100,000 of the population in 2000 to 1.53 in 2019. Conclusion The incidence of pediatric MS in Iran is high, and the development of diagnostic practices in the past decade in Iran has contributed to the detection of this high incidence.
Pyrido[1,2-e]purine: Design and Synthesis of Appropriate Inhibitory Candidates against the Main Protease of COVID-19

A series of tricyclic and polycyclic pyrido[1,2-e]purine derivatives were designed and synthesized via a two-step, one-pot reaction of 2,4-dichloro-5-amino-6-methylpyrimidine with pyridine under reflux conditions. Various derivatives of pyrido[1,2-e]purine were also synthesized by substituting the chlorine atom with secondary amines. After careful physiochemical and pharmacokinetic predictions, the inhibitory effects of the synthesized compounds against the main protease of SARS-CoV-2 have been evaluated by molecular docking and molecular dynamics approaches. The in silico results revealed that among all of the studied compounds, the morpholine/piperidine-substituted pyrido[1,2-e]purine derivatives are the best candidates as effective inhibitors of SARS-CoV-2.
The Blood Pressure Lowering Treatment Trialists’ Collaboration: methodological clarifications of recent reports

Epidemiological evidence has consistently shown that people with higher systolic or diastolic blood pressure are at greater risk of cardiovascular diseases. However, there has been limited randomized evidence to determine the role of blood pressure level at treatment initiation in the reduction of cardiovascular diseases risk. The extent to which other characteristics of individuals, such as prior disease history, age or sex, should be taken into account has also been controversial. Furthermore, effects on less commonly reported efficacy and safety outcomes remain underexplored. The Blood Pressure Lowering Treatment Trialists’ Collaboration has collected individual-level participant data from 52 randomized clinical trials, with more than 360 000 participants, and is now the largest source of individual-level data from randomized clinical trials of blood pressure-lowering treatment. This resource provides an unprecedented opportunity to address major areas of uncertainty relating to stratified efficacy and safety of antihypertensive therapy. Recent reports have demonstrated the power of pooled analyses of the Blood Pressure Lowering Treatment Trialists’ Collaboration dataset in filling long-standing gaps in our knowledge. However, there have been some misconceptions regarding the methods underpinning the recent reports, which we clarify in this article.
Heat-activated peracetic acid for degradation of diclofenac: kinetics, influencing factors and mechanism

ABSTRACT Heat-activated peracetic acid (PAA) was used to degrade diclofenac (DCF) in this study. Electron paramagnetic resonance and radical scavenging experiments proved that organic radicals (i.e. CH3C(=O)O• and CH3C(=O)OO•) were the primary active species for DCF removal in the heat/PAA process. The degradation efficiency of DCF increased with the increase of temperature or initial PAA concentration in the heat/PAA process, and the optimal reaction pH for DCF removal was neutral. The presence of NO3 − or SO4 2− insignificantly affected DCF degradation, while Cl− was favourable for DCF removal in this process. In contrast, an obvious inhibition on the removal of DCF was observed with the addition of natural organic matter, which might be responsible for the lower DCF removal in real waters. Finally, dechlorination, formylation, dehydrogenation and hydroxylation were proposed to be four degradation pathways of DCF in the heat/PAA system based on the five detected transformation products.

Effects of different doses of canagliflozin on blood pressure and lipids in patients with type 2 diabetes: a meta-analysis

Background: Canagliflozin is a sodium glucose-cotransporter-2 receptor inhibitor approved for the treatment of type 2 diabetes mellitus (T2DM). However, it is less prescribed due to increased LDL cholesterol (LDL-C), high incidence of urinary tract infection (UTI), high cost. Data on the effect of canagliflozin on blood pressure (BP) are also limited. We conducted a meta-analysis of randomized controlled trials (RCTs) to review dosedependent effects of canagliflozin on BP and lipids in patients with T2DM. Methods: A meta-analysis of RCTs in patients with T2DM was conducted. MEDLINE, the Cochrane Library of Trials and Clinicaltrials.gov were searched for relevant studies from January 2008 to May 2021. Results: Compared with placebo, canagliflozin 100 mg reduced SBP by 3.43 mmHg and DBP by 1.05 mmHg. Canagliflozin 100 mg increased LDL-C by 0.10mmol/l and HDL cholesterol (HDL-C) by 0.05 mmol/l. Compared with placebo, canagliflozin 300 mg reduced SBP by 4.75 mmHg and DBP by 1.69 mmHg. Canagliflozin 300 mg increased LDL-C by 0.16 mmol/l and HDL-C by 0.06 mmol/l. Compared with canagliflozin 100 mg, canagliflozin 300 mg further reduced SBP by 1.21 mmHg and DBP by 0.64 mmHg, and further increased LDL-C by 0.06 mmol/l and HDL-C by 0.02 mmol/l. Compared with placebo and canagliflozin 100 mg, canagliflozin 300 mg increased the risk of UTI. Conclusion: The current meta-analysis provides new evidence on different doses of canagliflozin as an antihypertensive agent in T2DM complicated by hypertension; however, LDL-C and the risk of UTI should be monitored.
Factors affecting ammonium capture by some Victorian lignites

ABSTRACT Nitrogen (N) loss from intensive animal husbandry leads to economic loss and environmental damage. Lignite has a demonstrated capacity to suppress ammonia (NH3) volatilisation from manure and this has been attributed to the pH, cation exchange capacity (CEC), pH buffer capacity and labile carbon (C) content of the lignite. Whilst lignite is effective in mitigating NH3 loss, the capacity for N retention and how this is influenced by the lignite's properties are not well studied. It is unclear if lignites from different mines will have comparable N retention under similar conditions. In this study, we characterised five Victorian lignites for their C-containing functional groups, surface morphology and chemical properties. These were then related to the ammonium ( ) adsorption capacity of the lignites using a batch isotherm technique. The contribution of biological immobilisation to the N retention capacity of the lignites was determined using 15N tracing in an incubation study. All lignites were acidic (pHH2O: 3.3–5.8; pHCaCl2: 3.0–5.4). The lignite had similar patterns of distribution of C functional groups with the carboxyl C between 2.8% and 5.3%. The maximum adsorption capacity (Qmax ) varied with the composition of the lignite and correlated positively with the lignites’ CEC, pH and carboxyl groups. Increase in pH, especially from pH >5, resulted in up to 3-fold increase in Qmax (25.6 mg g−1), likely due to deprotonation of carboxyl groups. Compared to adsorption, the biological immobilisation of did not play a substantial role in the overall lignite's N retention capacity. Highlights Victorian lignites were assessed for their retention capacity using adsorption isotherms and 15N tracing. adsorption capacity of lignites increased (up to 3-fold) with pH, especially from pH 5 to 7. Biological immobilisation did not play a substantial role in the retention capacity of the lignites. pH-dependent adsorption was the dominant means by which lignite retained . GRAPHICAL ABSTRACT
Assessment of Kratom Use Disorder and Withdrawal Among an Online Convenience Sample of US Adults

Introduction Since 2007, kratom use in the United States has increased, centered around nonmedical self-treatment of pain, psychiatric, and substance use disorder symptoms. Reports of kratom withdrawal have emerged amidst description of therapeutic effects, yet we know little about disordered use. Our objective was to assess Diagnostic and Statistical Manual-5 substance use disorder for kratom (“kratom use disorder,” KUD) and examine kratom withdrawal symptoms among those who ever used regularly. We also sought to identify clinical characteristics of respondents who qualified for current, remitted, or never KUD. Methods Between April and May 2021, we re-recruited online respondents who reported lifetime kratom use on an unrelated survey into our cross-sectional kratom survey study, permitting a diverse sample of current and former kratom-using persons. Results A total of 129/289 (44.6%) evaluable surveys were obtained. Over half (52.7%) of respondents never met KUD diagnostic criteria; 17.8% were assessed remitted, and 29.5% met current (past-year) KUD threshold. For past-year KUD, severity was: 14.0% mild, 7.0% moderate, and 8.5% severe. Pain, psychiatric symptoms, and polydrug use were found across all groups. KUD symptoms reflected increased use, tolerance, withdrawal, unsuccessful quit attempts, and craving; 9.3% reported decreases in important social, occupational, or recreational activities because of use. Withdrawal symptoms were moderate and included gastrointestinal upset, restlessness, anxiety, irritability, fatigue/low energy, and craving. Conclusions As assessed here, tolerance and withdrawal are primary KUD features rather than psychosocial impairments. As kratomis often used among persons with a myriad of health conditions, clinicians should be aware of and assess for kratom use and withdrawal.
Prediction of Institutionalization for Patients With Dementia in Taiwan According to Condition at Entry to Dementia Collaborative Care

This study aimed to examine the institutionalization rate in patients with dementia in Taiwan, identify the predictors of institutionalization, and conduct a mediation analysis of caregiver burden between neuropsychiatric symptoms and institutionalization. We analyzed data from a retrospective cohort registered in dementia collaborative care (N = 518). The analyses applied univariate and multivariate Cox proportional hazard regression with Firth’s penalized likelihood to assess the relationship between each predictor at entry and institutionalization for survival analysis. Thirty (5.8%) patients were censored due to institutionalization after a median follow-up of one-and-a-half years. Neuropsychiatric symptoms, loss of walking ability, and living alone predicted institutionalization. Caregiver burden may partially mediate the effects of neuropsychiatric symptoms and institutionalization. High caregiver burden due to presence of neuropsychiatric symptoms may partially contribute to institutionalization among people living with dementia in Taiwan. However, proper management of neuropsychiatric symptoms and caregiver empowerment may ameliorate institutionalization risk.
Construct validity of the focus on the outcomes of communication under six (FOCUS) total and profile scores for multilingual preschoolers: Considering functional speech skills

Abstract Purpose To conduct an exploratory study to establish construct validity of the Focus on the Outcomes of Communication Under Six (FOCUS) in the Jamaican context for FOCUS Total and Profile scores. Method Parents of a representative sample of 3-to-6-year-old Jamaican Creole (JC)-English-speaking simultaneous bilingual children completed the FOCUS in English, and the Intelligibility in Context Scale (ICS) in JC and in English. Children completed the Diagnostic Evaluation of Articulation and Phonology (DEAP) in both languages. Percent phonemes, consonants, and vowels correct were calculated using single word responses to DEAP items. Pearson correlations were completed to describe relationships between measurement scores. Result Convergent validity was found for FOCUS Total and ICS/JC scores. Convergent and divergent validity were found for specific FOCUS Profile scores and ICS/JC scores. Minimal evidence of convergent validity was found with FOCUS Total scores and transcription-based measures of speech production in JC and in English. Convergent and divergent validity were found between specific FOCUS Profile scores and some transcription-based measures of speech production in JC and in English. Conclusion This study provides evidence of construct validity for FOCUS Total and Profile scores. It also provides validity evidence for FOCUS scores in a multilingual context using a representative sample of children that serves to broaden the range of applicability of the FOCUS.
Varying Estimates of Sepsis among Adults Presenting to US Emergency Departments: Estimates from a National Dataset from 2002-2018

Background A variety of approaches to defining sepsis using administrative datasets have been previously reported. We aimed to compare estimates, demographics, treatment factors, outcomes and longitudinal trends of patients identified with sepsis in United States emergency departments (EDs) using differing sets of sepsis criteria. Methods We performed a cross-sectional study using the National Healthcare Ambulatory Medical Care Survey, a complex survey of nonfederal US ED encounters between 2002 to 2018. We obtained survey-weighted population-adjusted encounters of sepsis using the following criteria: explicit sepsis, severe sepsis, and quick Sequential Organ Failure Assessment (qSOFA) score combined with the presence of infection. Results Age-adjusted for US adults, 18.6, 16.1 and 8.9 encounters per 10 000 population were identified when using the explicit, severe sepsis and qSOFA definitions, respectively. A higher proportion of the explicit cohort was hospitalized and had blood cultures performed, compared to cohorts ascertained using severe sepsis and qSOFA criteria, though confidence intervals overlapped. Antibiotic use was highest in encounters meeting qSOFA criteria. When inspecting unweighted encounters meeting each set of criteria, there was minimal overlap, with only 3% meeting all three. Encounters meeting the explicit and severe sepsis criteria were increasing over time. Conclusion The explicit, severe sepsis and qSOFA criteria generated similar annual rates of presentation when applied to US ED encounters, with some evidence of the explicit sepsis cohort being higher acuity. There was minimal overlap of cases and instability in estimates when assessed longitudinally. Our findings inform research efforts to accurately identify sepsis among ED encounters using administrative data.
Augmentation of progestin signaling rescues testis organization and spermatogenesis in zebrafish with the depletion of androgen signaling

Disruption of androgen signaling is known to cause testicular malformation and defective spermatogenesis in zebrafish. However, knockout of cyp17a1, a key enzyme responsible for the androgen synthesis, in ar-/- male zebrafish paradoxically causes testicular hypertrophy and enhanced spermatogenesis. Because Cyp17a1 plays key roles in hydroxylation of pregnenolone and progesterone (P4), and converts 17α-hydroxypregnenolone to dehydroepiandrosterone and 17α-hydroxyprogesterone to androstenedione, we hypothesize that the unexpected phenotype in cyp17a1-/-;androgen receptor (ar)-/- zebrafish may be mediated through an augmentation of progestin/nuclear progestin receptor (nPgr) signaling. In support of this hypothesis, we show that knockout of cyp17a1 leads to accumulation of 17α,20β-dihydroxy-4-pregnen-3-one (DHP) and P4. Further, administration of progestin, a synthetic DHP mimetic, is sufficient to rescue testicular development and spermatogenesis in ar-/- zebrafish, whereas knockout of npgr abolishes the rescue effect of cyp17a1-/- in the cyp17a1-/-;ar-/- double mutant. Analyses of the transcriptomes among the mutants with defective testicular organization and spermatogenesis (ar-/-, ar-/-;npgr-/- and cyp17a-/-;ar-/-;npgr-/-), those with normal phenotype (control and cyp17a1-/-), and rescued phenotype (cyp17a1-/-;ar-/-) reveal a common link between a downregulated expression of insl3 and its related downstream genes in cyp17a-/-;ar-/-;npgr-/- zebrafish. Taken together, our data suggest that genetic or pharmacological augmentation of the progestin/nPgr pathway is sufficient to restore testis organization and spermatogenesis in zebrafish with the depletion of androgen signaling.
