The experience of living with human immunodeficiency virus among adolescents at Felege Hiwot Comprehensive Specialized Hospital Bahir-Dar, Northwest Ethiopia, A phenomenological study
Background Adolescents who have the human immunodeficiency virus face difficulties in their lives not just from the physical consequences of the illness but also from social stigma and discrimination. The quantitative side of this issue was the focus of earlier Ethiopian research. However, there hasn’t been any prior research done extensively in Ethiopia on the real-life experiences of teenagers infected with HIV. Therefore, in order to address the real issues that these teenagers encounter, it is imperative that we investigate their lived experiences as HIV-positive adolescents. Objective The goal is to investigate the experiences that adolescents at Felege Hiwot Comprehensive Specialized Hospital who are infected with HIV have on a daily basis. Method A phenomenological approach was conducted among thirteen purposively selected adolescents at Felege Hiwot Comprehensive Specialized Hospital, Bahir-Dar, northwest Ethiopia, from March 25 to April 30, 2023. Information saturation was used to estimate the sample size. Data was gathered through semi-structured open-ended interview guides and in-depth interview techniques. The talk was recorded using an audio recorder. The data was transcribed verbatim. The conceptual translation approach was used to translate the transcribed data from Amharic to English. For additional analysis, the translated data was entered into the Atlas.ti.8 program. To demonstrate findings, the inductive thematic analysis technique was applied using illustrative quotes. Colleague feedback, member checks, and a debriefing were used to guarantee the quality of the data. Result Eleven subthemes, including main theme of "lived with burdens of immunodeficiency virus," "disclosure," "ART adherence," and "future aspiration," were used to describe the findings. The participants discussed how difficult it has been for them to deal with social, emotional, and psychological difficulties in addition to living with the HIV infection. They kept their illness a secret from others out of fear of prejudice and stigma. In conclusion, adolescents infected with the human immunodeficiency virus faced a variety of difficulties related to their mental health, relationships, emotions, and compliance. It is advised that the community get ongoing, comprehensive health education in order to prevent stigmatization and discrimination against young people who have the virus.

Household transmission of SARS-CoV-2 in five US jurisdictions: Comparison of Delta and Omicron variants
Households are a significant source of SARS-CoV-2 transmission, even during periods of low community-level spread. Comparing household transmission rates by SARS-CoV-2 variant may provide relevant information about current risks and prevention strategies. This investigation aimed to estimate differences in household transmission risk comparing the SARS-CoV-2 Delta and Omicron variants using data from contact tracing and interviews conducted from November 2021 through February 2022 in five U.S. public health jurisdictions (City of Chicago, Illinois; State of Connecticut; City of Milwaukee, Wisconsin; State of Maryland; and State of Utah). Generalized estimating equations were used to estimate attack rates and relative risks for index case and household contact characteristics. Data from 848 households, including 2,622 individuals (median household size = 3), were analyzed. Overall transmission risk was similar in households with Omicron (attack rate = 47.0%) compared to Delta variant (attack rate = 48.0%) circulation. In the multivariable model, a pattern of increased transmission risk was observed with increased time since a household contact’s last COVID-19 vaccine dose in Delta households, although confidence intervals overlapped (0–3 months relative risk = 0.8, confidence interval: 0.5–1.2; 4–7 months relative risk = 1.3, 0.9–1.8; ≥8 months relative risk = 1.2, 0.7–1.8); no pattern was observed in Omicron households. Risk for household contacts of symptomatic index cases was twice that of household contacts of asymptomatic index cases (relative risk = 2.0, 95% confidence interval: 1.4–2.9), emphasizing the importance of symptom status, regardless of variant. Uniquely, this study adjusted risk estimates for several index case and household contact characteristics and demonstrates that few characteristics strongly dictate risk, likely reflecting the complexity of the biological and social factors which combine to impact SARS-CoV-2 transmission.

Healthcare providers’ (HCPs) perspectives in initiating discussion on mammogram screening, and their perceived barriers and enablers to screening in women—A qualitative study
Background Breast cancer is the most common cancer in women, and mammogram screening can reduce breast cancer mortality. Healthcare providers’ perspectives can have an impact on encouraging females to attend mammogram screening. Objective To understand healthcare providers’ (HCPs) perspectives in initiating discussion on mammogram screening, and their perceived barriers and enablers to screening in women. Method A qualitative descriptive study design was used. Focus group discussions (FGD) were conducted with a purposive sample of doctors and nurses from SingHealth Polyclinics between February 2019 to July 2020. “The Generalists’ Wheel of Knowledge, Understanding and Inquiry” was adopted as the conceptual framework to design the interview guide and analyse the data. Results Thirty participants consisting of 14 doctors and 16 nurses were interviewed across five FGDs. HCPs personal factors such as gender, their personal experience with mammogram, and years of work experience influenced counselling. They perceived that patients’ language, education status, previous experience with mammogram, misconceptions, and fear of mammogram results were potential barriers to mammogram. HCPs believed they had the knowledge to provide information and initiate discussions on mammogram screening. Healthcare factors were cost, accessibility to screening, consultation time constraints, and inadequate information in health records. Conclusion HCPs’ information mastery and personal experiences were enablers in encouraging females to attend mammogram screening. Lack of information in the health records was a barrier to providing continuity of care. Implications for practice Nurses should be opportunistic in initiating conversations and encourage women on mammogram screening when they visit the clinic. Training and being updated on mammography screening guidelines is important for clinicians to initiate and provide discussions on mammogram screening.

Comprehensive multi-metric analysis of user experience and performance in adaptive and non-adaptive lower-limb exoskeletons
Among control methods for robotic exoskeletons, biologically inspired control based on central pattern generators (CPGs) offer a promising approach to generate natural and robust walking patterns. Compared to other approaches, like model-based and machine learning-based control, the biologically inspired control provides robustness to perturbations, requires less computational power, and does not need system models or large learning datasets. While it has shown effectiveness, a comprehensive evaluation of its user experience is lacking. Thus, this study addressed this gap by investigating the performance of a state-of-the-art adaptive CPG-based exoskeleton control system (intelligent mode) under a multi-metric analysis (involving three-dimensional gait analysis, muscle activity, oxygen consumption, user comfort, and exoskeleton performance scores) and comparing it to a standard commercial exoskeleton control system (default mode). A cross-over design with randomized allocation in Thai healthy and independently walking adults ensured participants experienced both modes. All participants were assigned into two groups to receive an alternate sequence of walking with the intelligent mode or the default mode of the lower-limb exoskeleton Exo-H3 at high and normal speed. From eight participants, the intelligent mode-driven exoskeleton (adaptive exoskeleton) showed a significantly lower velocity, stride, and step lengths than the default mode-driven exoskeleton (non-adaptive exoskeleton). This setup significantly increased anterior pelvic tilt during mid-swing at normal speed (3.69 ± 1.77 degrees, p = 0.001) and high speed (2.52 ± 1.69 degrees, p = 0.004), hip flexion during stance phase with ankle dorsiflexion, and used less oxygen consumption at high speed (-2.03 ± 2.07 ml/kg/min) when compared to the default one. No significant differences of muscle activity, user comfort and exoskeleton performance scores between the two modes. Further exoskeletal modification in terms of hardware and control is still needed to improve the temporal spatial, kinematics, user comfort, and exoskeleton performance.

The NE/AAT/CBG axis regulates adipose tissue glucocorticoid exposure
AbstractCorticosteroid binding globulin (CBG; SERPINA6) binds >85% of circulating glucocorticoids but its influence on their metabolic actions is unproven. Targeted proteolytic cleavage of CBG by neutrophil elastase (NE; ELANE) significantly reduces CBG binding affinity, potentially increasing ‘free’ glucocorticoid levels at sites of inflammation. NE is inhibited by alpha-1-antitrypsin (AAT; SERPINA1). Using complementary approaches in mice and humans to manipulate NE or AAT, we show high-fat diet (HFD) increases the NE:AAT ratio specifically in murine visceral adipose tissue, an effect only observed in males. Notably, HFD-fed male mice lacking NE have reduced glucocorticoid levels and action specifically in visceral adipose tissue, with improved glucose tolerance and insulin sensitivity, independent of systemic changes in free glucocorticoids. The protective effect of NE deficiency is lost when the adrenals are removed. Moreover, human asymptomatic heterozygous carriers of deleterious mutations in SERPINA1 resulting in lower AAT levels have increased adipose tissue glucocorticoid levels and action. However, in contrast to mice, humans present with systemic increases in free circulating glucocorticoid levels, an effect independent of HPA axis activation. These findings show that NE and AAT regulate local tissue glucocorticoid bioavailability in vivo, providing crucial evidence of a mechanism linking inflammation and metabolism.
High genetic variation, low differentiation, and Pleistocene expansions of the migratory and endangered long-nosed tequila bat, Leptonycteris nivalis, inferred using both maternal and paternal genetic markers
Tequila bats (genus Leptonycteris) have gained attention for their critical role in pollinating different plant species, especially Agave spp. and columnar cacti. Leptonycteris nivalis is the largest nectar-feeding bat in the Americas, and the females exhibit migratory behavior during the breeding season. Due to its relatively small and seemingly declining population sizes, this species is protected by government agencies in the United States and Mexico. We conducted population genetics and phylogeographic analyses to elucidate the genetic structure and demographic history of the species using two mitochondrial markers and a Y chromosome-associated gene, to describe both maternal and paternal lineages. We estimated high haplotypic diversity measures for the different markers (Dloop—Hd = 0.775; Cyt-b—Hd = 0.937; DBY -Hd = 0.946). We found that geographic genetic differentiation is very low, and there is high connectivity among localities. The estimated divergence time between L. nivalis and L. yerbabuenae, the other species in the genus found in Mexico, aligns with previous estimates for the genus (6.91–9.43 mya). A demographic expansion was detected approximately at 600 ka—700 ka (thousands of years ago). The historical demographic changes observed in L. nivalis appear to be associated with environmental shifts during the Pleistocene, which likely impacted the distribution range of the plants that these bats feed on, such as Agave species.
Neoadjuvant or concurrent atezolizumab with chemoradiation for locally advanced cervical cancer: a randomized phase I trial
AbstractCombined immune checkpoint blockade (ICB) and chemoradiation (CRT) is approved in patients with locally advanced cervical cancer (LACC) but optimal sequencing of CRT and ICB is unknown. NRG-GY017 (NCT03738228) was a randomized phase I trial of atezolizumab (anti-PD-L1) neoadjuvant and concurrent with CRT (Arm A) vs. concurrent with CRT (Arm B) in patients with high-risk node-positive LACC. The primary endpoint was the fraction of expanded tumor-associated T-cell receptor (TCR) clones in blood at day 21 as a surrogate measure of anti-tumor immune response. Secondary objectives were safety and feasibility, 2-year disease-free survival (DFS), and predictive value of PD-L1 expression. Forty patients were randomized, 36 received treatment, and 25 were evaluable for the primary endpoint. After cycle 1, there was peripheral expansion of higher proportion of tumor-associated TCR clones in Arm A than in Arm B (p = 0.0025) that remained higher at day 21, meeting the pre-specified endpoint on two-sample T-test (p = 0.052), but not on sensitivity analysis by Wilcoxon test (p = 0.13). At the median follow up of 25.8 months, 2-year DFS was 76% in Arm A and 56% in Arm B (p = 0.28). There were no new safety signals. In conclusion, neoadjuvant ICB prior to CRT was safe and was associated with immunologically and clinically favorable outcomes, warranting larger confirmatory studies.
