Studying human immunodeficiency virus type 1 (HIV-1) superinfection is important to understand virus transmission, disease progression, and vaccine design. But detection remains challenging, with low sampling frequencies and insufficient longitudinal samples.
Using the Swiss HIV Cohort Study (SHCS), we developed a molecular epidemiology screening for superinfections. A phylogeny built from 22 243 HIV-1 partial polymerase sequences was used to identify potential superinfections among 4575 SHCS participants with longitudinal sequences. A subset of potential superinfections was tested by near-full-length viral genome sequencing (NFVGS) of biobanked plasma samples.
Based on phylogenetic and distance criteria, 325 potential HIV-1 superinfections were identified and categorized by their likelihood of being detected as superinfections due to sample misidentification. NFVGS was performed for 128 potential superinfections; of these, 52 were confirmed by NFVGS, 15 were not confirmed, and for 61 sampling did not allow confirming or rejecting superinfection because the sequenced samples did not include the relevant time points causing the superinfection signal in the original screen. Thus, NFVGS could support 52 of 67 adequately sampled potential superinfections.
This cohort-based molecular approach identified, to our knowledge, the largest population of confirmed superinfections, showing that, while rare with a prevalence of 1%-7%, superinfections are not negligible events.

Eukaryotic organisms have evolved robust defensive mechanisms to suppress their activity, yet TEs can escape suppression and proliferate, creating strong selective pressure for host defense to adapt. This genomic conflict fuels a never-ending arms race that drives the rapid evolution of TEs and recurrent positive selection of genes involved in host defense; the latter has been shown to contribute to postzygotic hybrid incompatibility. However, how TE proliferation impacts genome and regulatory divergence remains poorly understood. Here, we report the highly complete and contiguous (N50 = 33.8-38.0 Mb) genome assemblies of seven closely related Drosophila species that belong to the nasuta species group-a poorly studied group of flies that radiated in the last 2 My. We constructed a high-quality de novo TE library and gathered germline RNA-seq data, which allowed us to comprehensively annotate and compare TE insertion patterns betwon of host suppression of resident TEs is a major strategy to persist over evolutionary times. Altogether, our results shed light on the heterogenous and context-dependent nature in which TEs affect gene regulation and the dynamics of rampant TE proliferation amidst a recently radiated species group.A mild, efficient, and metal-free synthetic protocol for the synthesis of β-amino alcohols is reported. tetrathiomolybdate The reaction proceeds at room temperature with only 0.5 mol % catalyst loading and affords β-amino alcohol derivatives in excellent yield. This protocol is well-tolerated by a wide range of styrene oxide and aniline derivatives. A notably efficacious gram-scale synthesis is also reported with a high TON=842. Further, the Hammett correlation study was also performed to identify the rate-determining step.A dysregulated immune response plays a critical role in systemic lupus erythematosus (SLE) pathogenesis. Environmental factors such as viruses, including coronavirus 2 (COVID-19), have been described to play a role in SLE presentation and exacerbation. These viruses trigger a host's humoral and cellular immunities typically essential in elimination of the viral infection. We present a case of a Hispanic male who developed new-onset lupus nephritis class II after a COVID-19 infection.
Brain metastasis (BM) are uncommon among women with epithelial ovarian cancer (EOC). The frequency, risk factors and clinical repercussions of BM in these patients are not well described.
We retrospectively evaluated EOC patients treated at our center from 2002 to 2020 and assessed their clinical parameters, risk for BM development and association with overall survival (OS). This cohort has a known high frequency of BRCA mutation carriers (
) due to women of Ashkenazi Jewish descent.
Among 1035 EOC patients, 29 (2.8%) were diagnosed with BM. The prevalence of
mutations was more common among women with BM (56.5% vs. 34.3%,
= 0.033). The BM rate in patients with
was higher than the BM rate in those with wildtype BRCA (
; 5.1% vs. 2.1%, OR = 2.6; 95% CI 1.2-5.4,
= 0.013). Median time from diagnosis to BM and from disease recurrence to BM was longer among patients with
. Median OS was not significantly different among patients with BM versus those without BM (59.4 vs. 73.4 months,
= 0.243). After BM diagnosis, median OS was not statistically significantly different between patients with
and those with
(20.6 vs. 12.3 months,
= 0.441). Treatment with poly (ADP-ribose) polymerase inhibitors and bevacizumab had no impact on subsequent development of BM.
BM are rare among EOC patients. However, the risk is three-fold higher among patients with
. BM do not significantly alter OS among EOC patients. The higher rate of BM in patients with
may be related to longer OS in this subpopulation.

Atomoxetine (ATX) is a non-central stimulant and a standard treatment for adult attention-deficit/hyperactivity disorder (ADHD). The long-term efficacy of Atomoxetine is about 40% at 6 months. The variability in efficacy between individuals is thought to be related to patient-specific factors, but no detailed research has been conducted. In this retrospective cohort study, we aimed to identify the factors associated with Atomoxetine efficacy.
A total of 147 patients with attention-deficit/hyperactivity disorder aged ≥18 years who were using Atomoxetine for the first time were included in this study. The outcome was treatment success (treatment maintained for at least 6 months and improvement in symptoms). Symptom assessment was based on the overall improvement in symptoms judged by an expert physician.
Of the patient sample, 103 (70.1%) achieved the outcome. Logistic regression analysis identified "the maximum dose of ATX" and "gambling habit" as factors associated with efficacy ( P < 0.05). In the process of Atomoxetine titration, the larger the maximum dose, the higher the efficacy was shown to be. Gambling habits may be indicative of impulsivity, which is among the core symptoms of attention-deficit/hyperactivity disorder. Thus, a gambling habit may be considered a surrogate marker for impulsivity.
Knowledge of these factors will help healthcare professionals to predict the likely efficacy of Atomoxetine in a given patient before subscribing it, facilitating individualized pharmacotherapy for adult attention-deficit/hyperactivity disorder.

Substance P is a sensory neuropeptide increasingly used as a biomarker for ocular and systemic neuropathic conditions. Due to the limited studies on tear storage conditions compared to other bodily fluids including blood and urine, the aim of this study was to investigate whether different storage durations at 4 °C can impact on substance P concentrations prior to storage at -80 °C. This is important to assess potential practical limitations in the handling and storage of tear fluid essential.
Tears were collected and pooled from both eyes of 31 healthy participants using the flush tears method. The samples were centrifuged and aliquoted into three sets of microcentrifuge tubes with each stored at 4 °C for <2 h, 4 h or 6 h (Timepoints 1, 2 or 3). After each respective storage duration, the aliquoted samples were than stored at -80 °C before analysis, within 6 months. Tears were analyzed for the concentration of substance P and the total protein content (TPC).

Here, we report a single centre experience of real-world efficacy, long-term side effects, and challenges of this treatment. This was a retrospective analysis. All patients linked with our centre who had Lu-PRRT were included. Clinicopathological data were analysed using descriptive statistics, Kaplan-Meier, and Cox regression. A total of 45 patients had Lu-PRRT, of those 30 (67%) were males, and 13 (29%) were more than 65 years old. The primary site was small intestine in 30 (67%) patients, pancreas in seven (16%) patients, and lung in three (7%) patients. The tumor was grade 1 in 15 (35%) patients, grade 2 in 22 (48%) patients, and grade 3 in six (13%) patients. A total of 41 (91%) patients had liver metastasis, and 20 (44%) patients had carcinoid syndrome. Lu-PRRT was the second-line therapy in all patients.

Nursing student perceptions of potential sources of trauma exposure also known as potentially traumatic events (PTEs) during nursing school are lacking in the literature. The purpose of this study was to describe nursing students' perceptions of potential sources of trauma exposure during nursing school at one private school of nursing. Four online, synchronous focus groups with undergraduate nursing students were conducted in April 2020. Four themes emerged from analysis of focus group transcripts related to potential sources of trauma exposure Individual-oriented interpersonal sources, nursing student-oriented interpersonal sources, nursing student-oriented institutional and organizational sources, and individual-oriented community sources. Participants focused on nursing student-oriented, interpersonal, and institutional and organizational potential sources of trauma exposure, while minimizing individual-oriented, community, and macro-level potential sources of student trauma exposure during nursing school. Findings advance discussions of organizational, systems, and community PTEs in nursing education. Trauma-informed educational and healthcare systems that promote the academic and career success of nursing students should be considered in PTE prevention efforts.
