Size, shape, and direction matters: Matching secondary genital structures in male and female mites using multiple microscopy techniques and 3D modeling

Studies of female genital structures have generally lagged behind comparable studies of male genitalia, in part because of an assumption of a lower level of variability, but also because internal genitalia are much more difficult to study. Using multiple microscopy techniques, including video stereomicroscopy, fluorescence microscopy, low-temperature scanning electron microscopy (LT-SEM), and confocal laser scanning microscopy (CLSM) we examined whether the complex sperm transfer structures in males of Megalolaelaps colossus (Acari: Mesostigmata) are matched by similarly complex internal structures in the female. While both LT-SEM and CLSM are well suited for obtaining high-quality surface images, CLSM also proved to be a valuable technique for observing internal anatomical structures. The long and coiled sperm transfer organ on the chelicera of the males (spermatodactyl) largely matches an equally complex, but internal, spiral structure in the females in shape, size, and direction. This result strongly suggests some form of genital coevolution. A hypothesis of sexual conflict appears to provide the best fit for all available data (morphology and life history).
Development and Validation of a Simple and Sensitive RP-HPLC Method for Determination of Rifampicin in Bulk and Tablets

A simple, precise, sensitive, economic, reproducible and validated RP-HPLC method was developed for the quantitative determination of Rifampicin in bulk and tablet dosage form. Analysis was carried out using acetonitrile: 0.1% orthophosphoric acid (80:20) mobile phase at 0.4 mL/min flow rate and Zorbax Eclipse Plus C18 columnas stationary phase with detection wavelength of 480 nm. The retention time was found to be 4.7 min. The method showed good linearity in the range of 1.95-250 μg/mL with correlation coefficient of 0.9996. Limit of detection and limit of quantification was found to be 0.607 and 1. 841μg/mL, respectively. The method was validated for specificity, linearity, precision, accuracy, and limit of detection and quantification following ICH guidelines.
Association Between Central Sensitization and Increasing Prevalence of Nocturnal Knee Pain in the General Population with Osteoarthritis from the Iwaki Cohort Study

Purpose Knee pain is associated with osteoarthritis (OA) and increases during this condition; however, its correlation with central sensitization (CS) in arthritis patients requires greater understanding. The present cross-sectional cohort study to explore the prevalence of knee OA, nocturnal knee pain and disability in general population and to examine the association of CS with sleep quality in Japanese general population. Patients and Methods From among 1056 community-dowelling volunteers, 942 were enrolled as participants in this study. Bilateral weight-bearing anterior-posterior knee radiographs were classified by the Kellgren–Lawrence grade. Nocturnal knee pain and disability were assessed with self-reported questionnaires. Using the CS inventory with nine items (CSI-9), CS was defined as 10 points or higher. Sleep quality was scored using the Pittsburgh Sleep Quality Index (PSQI). Linear regression analysis, adjusted by age, sex, body mass index, Kellgren-Lawrence grade, nocturnal knee pain, and lifestyle habits, was performed to investigate the association of CS with PSQI. Results The prevalence of OA, nocturnal knee pain, and disability was 37.9%, 7.6%, and 6.2%, respectively. The mean CSI-9 score was 4.9 ± 4.4, with a CS prevalence of 14.0%. The mean PSQI score was 3.9 ± 2.4, which was correlated with the CSI-9 value. CS was not correlated with OA severity; however, nocturnal knee pain prevalence increased from 13.3% to 25.5% in knee OA patients with CS. The CSI-9 value correlated with PSQI total score and subscales. Conclusion Knee OA severity correlated with nocturnal pain and disability; however, its association with CS was unproven. The combined effect of knee OA and CS elevated nocturnal pain and disability, resulting in diminished sleep quality.
Basic Pan-Cancer Analysis of the Carcinogenic Effects of Cyclin-Dependent Kinase 4 (CDK4) in Human Surface Tumors

Although the evidence based on current human, animal, or molecular biology can explain some of the relationships between CDK4 and cancer, there is no pan-cancer analysis of the gene CDK4 in human skin tumors. Therefore, the potential carcinogenic effects of CDK4 in 33 tumors were initially explored in the datasets of the GEO (Gene Expression Omnibus) and the CGA (Cancer Genome Atlas). We found that CDK4 was highly expressed in most cancers and that CDK4 performance levels significantly correlated with the prognosis of cancer patients. These were found in our preliminary exploration. In addition, we used the dataset in tumors such as cutaneous melanoma or lung adenocarcinoma and found increased levels of phosphorylation of r24 l/C/h/s. In addition, fibroblast infiltration associated with CDK4 cancer was observed in head and neck, sarcoma, and melanoma skin. Using this pan-cancer study, our group has provided a comprehensive preliminary demonstration of the oncogenic effects of the CDK4 gene on different human skin tumors.
Different Clinicopathologic and Computed Tomography Imaging Characteristics of Primary and Acquired EGFR T790M Mutations in Patients with Non-Small-Cell Lung Cancer

Purpose Although patients with primary and acquired epidermal growth factor receptor (EGFR) T790M positive non-small-cell lung cancer (NSCLC) respond to osimertinib treatment, the optimal treatment strategy differs for these two groups of patients. This study aimed to compare the clinicopathologic and computed tomography (CT) imaging characteristics between primary and acquired EGFR T790M mutations in patients with NSCLC before treatment. Patients and Methods We enrolled two groups of patients with primary or acquired EGFR T790M mutation NSCLC (n = 103 per group) from January 2012 to December 2019. We analyzed their clinicopathologic and CT characteristics and differences between the groups. The groups were further categorized based on 21L858R and 19del to exclude the effect of coexistent mutations. Results Primary, compared to acquired, T790M mutation tends to coexist with 21L858R (P < 0.001), exhibiting earlier tumor stage (P < 0.001), higher differentiation (P = 0.029), higher proportion of lepidic subtype adenocarcinoma (P < 0.001), and significant associations with some CT features (multiple primary lung cancers, ground-glass opacity, air bronchogram, and vacuole sign [all P < 0.001]). The combined model, composed of clinicopathologic and conventional CT signature and CT-radiomic signature, showed good discriminative ability with the area under the receiver operating characteristic curve 0.90 and 0.91 in the training and validation datasets, respectively. The T790M mutation contributed to these differences independently of coexistent mutations. Conclusion We identified clinicopathologic and CT imaging differences between primary and acquired T790M mutations. These findings provide insights into developing future personalized T790M mutation status-based theranostic strategies.
Findings From a Provider-Led, Mindfulness-Based, Internet-Streamed Yoga Video Addressing the Psychological Outcomes of Breast Cancer Survivors

The aim of this study was to explore the psychological outcomes of a mindfulness-based Internet-streamed yoga video in breast cancer survivors. A one-group, repeated-measures, purposive sample using a directed qualitative descriptive and convergent mixed-methods approach was used. Participants were recruited from breast oncology practices across 2 settings in the northeastern United States in April 2019. Education about the video was provided, and the link to the video was sent to participants. Demographic information, Knowing Participation in Change Short Form (KPCSF), Short Warwick-Edinburgh Mental Well-being Scale (WEMWBS), and the Generalized Anxiety Distress Scale (GAD-7) were obtained at baseline and at 2 and 4 weeks. A semistructured interview was conducted at 4 weeks. Thirty-five women (mean age = 56 years) participated. A one-group, repeated-measures analysis of variance indicated statistically significant changes occurred in all measures between week 0 and week 4: decreased GAD (t = −2.97, P = .004), improved WEMWBS (t = 2.52, P = .008), and increased KPC (t = 2.99, P = .004). Qualitative findings suggest the overall experience of the video was positive and the women would recommend its use to others. Improvements in all psychological measures were achieved with video use. Findings indicate an improvement in psychological measures and support the theory of Knowing Participation in Change. This work further contributes to accessible, flexible interventions available through the Internet and/or mobile applications aimed at improving breast cancer survivorship.
Perceptions of Stakeholders Toward “Hospital at Home” Program in Singapore: A Descriptive Qualitative Study

Objective Hospital at Home (HaH) programs have been shown to improve quality of care and patient satisfaction, and reduce bed occupancy rate in hospitals. Despite the prevalence of HaH in Western countries, studies in Asia are limited and the perception of HaH remains underexplored in Asian context. Understanding the perceptions of stakeholders is vital before implementing HaH in any new settings. Thus, the aim of this study is to explore the perceptions of referring physicians, care providers, patients, and caregivers on HaH programs in a multiracial country such as in Singapore. Methods This study used a descriptive qualitative design. Participants from 2 tertiary hospitals in Singapore, including 13 referring physicians, 10 care providers, 15 patients, and 3 caregivers, were interviewed between June 2020 and September 2020. Data were analyzed using inductive thematic analysis. Results The overarching theme titled “The stakeholders’ perception on HaH” was pillared by 4 main themes: (1) patients suitable for HaH; (2) perceived advantages and benefits of HaH; (3) perceived risks, anxiety, and concerns about HaH; and (4) potential enablers of HaH. Overall, the findings reported that most of the stakeholders embraced HaH. Timely medical interventions and support from care providers were reportedly important factors to maintain patient safety and quality of care. The importance of having adequate resources and sound financing mechanisms to develop a successful HaH program was also highlighted. Conclusions This study offered insights into HaH from the perspectives of stakeholders in Singapore and facilitate the planning of future HaH pilot programs in multiracial Singapore and other Asian countries.
Complete Genome Sequences of Bacillus cereus Group Phages AaronPhadgers, ALPS, Beyonphe, Bubs, KamFam, OmnioDeoPrimus, Phireball, PPIsBest, YungSlug, and Zainny

Here, we report genome sequences of 10 Bacillus cereus group-infecting bacteriophages. Each virus was isolated from an environmental sample, contained a double-stranded DNA genome, and belonged to the Myoviridae family. Nine phages exhibit a conserved genome structure, and one phage appears novel in genome structure, sequence, and protein content.

Neighborhood Social Cohesion and Mobility Limitations Among Community-dwelling Older Americans: The Mediating Roles of Depressive Symptoms and Mastery

Neighborhood environment plays an important role in late-life health; yet, the social aspect of neighborhood environment and its impact on mobility limitations have rarely been examined. This nonexperimental, cross-sectional study examines the relationship between neighborhood social cohesion and mobility limitations and the potential mediators (i.e., depressive symptoms, mastery) of this relationship. A total of 8,317 Americans aged 65 years and older were selected from the Health and Retirement Study. Using ordinary least squares regressions, this study shows that neighborhood social cohesion was negatively associated with mobility limitations (B = −0.04, p < .01). A Sobel test of mediation indicated that this relationship was significantly mediated by depressive symptoms (z = −9.10, p < .001) and mastery (z = −8.86, p < .001). Findings suggest that neighborhood cohesion can reduce mobility limitations through mitigating depressive symptoms and increasing mastery. Future research should disentangle the temporal ordering of the mediators.
Polygenic Adaptation and Clonal Interference Enable Sustained Diversity in Experimental Pseudomonas aeruginosa Populations

Abstract How biodiversity arises and can be maintained in asexual microbial populations growing on a single resource remains unclear. Many models presume that beneficial genotypes will outgrow others and purge variation via selective sweeps. Environmental structure like that found in biofilms, which are associated with persistence during infection and other stressful conditions, may oppose this process and preserve variation. We tested this hypothesis by evolving Pseudomonas aeruginosa populations in biofilm-promoting arginine media for 3 months, using both a bead model of the biofilm life cycle and planktonic serial transfer. Surprisingly, adaptation and diversification were mostly uninterrupted by fixation events that eliminate diversity, with hundreds of mutations maintained at intermediate frequencies. The exceptions included genotypes with mutator alleles that also accelerated genetic diversification. Despite the rarity of hard sweeps, a remarkable 40 genes acquired parallel mutations in both treatments and often among competing genotypes within a population. These incomplete soft sweeps include several transporters (including pitA, pntB, nosD, and pchF) suggesting adaptation to the growth media that becomes highly alkaline during growth. Further, genes involved in signal transduction (including gacS, aer2, bdlA, and PA14_71750) reflect likely adaptations to biofilm-inducing conditions. Contrary to evolution experiments that select mutations in a few genes, these results suggest that some environments may expose a larger fraction of the genome and select for many adaptations at once. Thus, even growth on a sole carbon source can lead to persistent genetic and phenotypic variation despite strong selection that would normally purge diversity.
A Randomized Controlled Trial on the Efficacy of Integrated Yoga on Pregnancy Outcome

Physiological and biochemical changes occur in pregnancy to nurture the developing fetus. Pregnancy-related experience is unique to every woman. Pregnancy symptoms and complications can range from mild to severe. Many women can lower their risk by performing different therapies. In this context, the present study targets to evaluate the efficacy of integrated yoga consisting of (asanas and pranayama) on pregnancy to reduce the risk of complications. This study is a prospective randomized controlled single-blinded trial with parallel arms: the intervention arm received specific integrated yoga therapy; the control arm received routine standard care from 18 to 22 weeks of gestation until delivery. The incidence of preeclampsia and preterm delivery was lower in the intervention arm. Women in the intervention arm delivered at higher gestational age. Apgar scores and birth weights of neonates were significantly higher in the intervention arm. The findings suggest that yoga is a safe and effective intervention during pregnancy to reduce or prevent pregnancy-related complications. However, further randomized controlled trials are needed to provide firmer evidence regarding the utility and validity of yoga intervention during pregnancy.
Efficacy of face masks against respiratory infectious diseases: a systematic review and network analysis of randomized-controlled trials

During the ongoing COVID-19 pandemic, face masks are among the most common and practical control measures used globally in reducing the risk of infection and disease transmission. Although several studies have investigated the efficacy of various face masks and respirators in preventing infection, the results have been inconsistent. Therefore, we performed a systematic review and network meta-analysis (NMA) of the randomized-controlled trials (RCTs) to assess the actual efficacy of face masks in preventing respiratory infections. We searched nine electronic databases up to July 2020 to find potential articles. We accepted trials reporting the protective efficacy of face masks against respiratory infections, of which the primary endpoint was the presence of respiratory infections. We used the ROB-2 Cochrane tool to grade the trial quality. We initially registered the protocol for this study in PROSPERO (CRD42020178516). Sixteen RCTs involving 17 048 individuals were included for NMA. Overall, evidence was weak, lacking statistical power due to the small number of participants, and there was substantial inconsistency in our findings. In comparison to those without face masks, participants with fit-tested N95 respirators were likely to have lesser infection risk (RR 0.67, 95% CI 0.38–1.19, P-score 0.80), followed by those with non-fit-tested N95 and non-fit-tested FFP2 respirators that shared the similar risk, (RR 0.73, 95% CI 0.12–4.36, P-score 0.63) and (RR 0.80, 95% CI 0.38–1.71, P-score 0.63), respectively. Next, participants who donned face masks with and without hand hygiene practices showed modest risk improvement alike (RR 0.89, 95% CI 0.67–1.17, P-score 0.55) and (RR 0.92, 95% CI 0.70–1.22, P-score 0.51). Otherwise, participants donning double-layered cloth masks were prone to infection (RR 4.80, 95% CI 1.42–16.27, P-score 0.01). Eleven out of 16 RCTs that underwent a pairwise meta-analysis revealed a substantially lower infection risk in those donning medical face masks (MFMs) than those without face masks (RR 0.83 95% CI 0.71–0.96). Given the body of evidence through a systematic review and meta-analyses, our findings supported the protective benefits of MFMs in reducing respiratory transmissions, and the universal mask-wearing should be applied—especially during the COVID-19 pandemic. More clinical data is required to conclude the efficiency of cloth masks; in the short term, users should not use cloth face masks in the outbreak hot spots and places where social distancing is impossible.
Controlling the spatial dimensions of visual stimuli in online experiments

There are clear benefits to using an online environment for human subjects’ research, for instance, rapid data collection and access to a diverse body of potential participants. One distinct drawback of online environments as compared to laboratory environments is the relative lack of control over experiment conditions. For research into human vision, a specific concern is the relative lack of control over angular stimulus dimension in an online setting. This paper examines three approaches to estimating a participant's viewing distance online, and quantifies the magnitude of the error in angular stimulus size associated with each method. For each method, the average expected error is smaller than 20% of the intended stimulus size, and for the best method it is close to 10%. This paper provides a discussion of the benefits and drawbacks of each of the three methods, as well as parameter values and computer code that will facilitate the use of these methods in future online studies.
Machine learning‐enabled multitrust audit of stroke comorbidities using natural language processing

With the increasing adoption of electronic records in the health system, machine learning‐enabled techniques offer the opportunity for greater computer‐assisted curation of these data for audit and research purposes. In this project, we evaluate the consistency of traditional curation methods used in routine clinical practice against a new machine learning‐enabled tool, MedCAT, for the extraction of the stroke comorbidities recorded within the UK's Sentinel Stroke National Audit Programme (SSNAP) initiative.
Long-term survival in a dog with primary hepatic neuroendocrine tumor treated with toceranib phosphate

Primary hepatic neuroendocrine tumors (PHNETs) are rare in dogs, and limited information exists about the treatment of these tumors. A 12-year-old castrated male French bulldog was presented to our clinic with gastrointestinal signs. Diagnostic tests revealed increased hepatic enzyme levels, a mass in the hepatic quadrate lobe, multiple intrahepatic nodules, and enlarged hepatic hilar lymph nodes. The liver mass was diagnosed cytologically as a malignant epithelial tumor suspected to be of neuroendocrine origin. The dog was treated with single-agent toceranib phosphate (TOC) and survived 25.1 months after the initial presentation. On necropsy, a liver mass was found and was subsequently diagnosed as a PHNET on histopathology. To the best of our knowledge, this is the first report of long-term survival in a dog with PHNET treated with TOC.
Efficacy and safety of colchicine in patients with coronary artery disease: A systematic review and meta‐analysis of randomized controlled trials

Inflammation plays a central role in the pathogenesis and clinical manifestations of atherosclerosis. Randomized controlled trials have investigated the potential benefit of colchicine in reducing cardiovascular (CV) events in patients with coronary artery disease (CAD) but produced conflicting results. The aim of this meta‐analysis was to evaluate the efficacy and safety of colchicine in patients with CAD.
How to Effectively Decrease Patient Co-Payments of High-Cost Drugs Through Innovation: Lessons From the Karmanos Specialty Pharmacy

PURPOSE: High-cost drugs impose a financial burden on patients with cancer. Karmanos Specialty Pharmacy (KSP) developed a process to automate financial assistance (FA) applications to decrease patient drug cost. We evaluate the outcomes of this program on cost to patients and payers. METHODS: This is an observational, retrospective study of the KSP claims data set from January to December 2019, accessed by 13 statewide cancer centers within Michigan. Drug cost of patients, payers, FA (funds to lower patient drug cost), and types of FA were obtained. A subset analysis was performed to determine drug delivery times. RESULTS: In 2019, 869 prescriptions and 1,722 prescription fills were provided to 463 patients through KSP. The total cost of drug claims was approximately $10 million US dollars (USD) among Medicare patients (58%), approximately $3.4 million USD for privately insured patients (20%), and approximately $3.7 million USD for Medicaid patients (22%). Twenty-seven percent of patients (22% of all prescription fills) required additional FA with initial total co-payment claims of $335,216 USD. $280,988 USD of FA was obtained, which substantially lowered total patient costs by 81%. $250,818 USD of FA obtained was from foundation grants (327 fills), and $21,441 USD from manufacturer co-pay cards (47 fills). An additional $12,260 USD (12 fills) from a Karmanos Patient Assistance Fund was used. There was high dependence on foundation grant assistance among Medicare patients (33% of claims). In a subset analysis, the median time from prescription written to delivery to the patient was < 7 days (0-56 days). CONCLUSION: Twenty-seven percent of patients (22% of prescriptions fills) in 2019 required additional FA for high-cost drugs. KSP substantially reduced patient cost by implementing an efficient process using additional pharmacy assistants to obtain FA. Need help with tweets! (I thought it was 140 characters? ) here's 2 potentials:-27% of cancer patients require financial assistance for high-cost drugs, mostly through foundation grants, with the highest burden on Medicare.
