Gut microbiome correlates of recurrent urinary tract infection: a longitudinal, multi-center study

Urinary tract infections (UTI) affect approximately 250 million people annually worldwide. Patients often experience a cycle of antimicrobial treatment and recurrent UTI (rUTI) that is thought to be facilitated by a gut reservoir of uropathogenic Escherichia coli (UPEC). 125 patients with UTI caused by an antibiotic-resistant organism (ARO) were enrolled from July 2016 to May 2019 in a longitudinal, multi-center cohort study. Multivariate statistical models were used to assess the relationship between uropathogen colonization and recurrent UTI (rUTI), controlling for clinical characteristics. 644 stool samples and 895 UPEC isolates were interrogated for taxonomic composition, antimicrobial resistance genes, and phenotypic resistance. Cohort UTI gut microbiome profiles were compared against published healthy and UTI reference microbiomes, as well as assessed within-cohort for timepoint- and recurrence-specific differences. Risk of rUTI was not independently associated with clinical characteristics. The UTI gut microbiome was distinct from healthy reference microbiomes in both taxonomic composition and antimicrobial resistance gene (ARG) burden, with 11 differentially abundant taxa at the genus level. rUTI and non-rUTI gut microbiomes in the cohort did not generally differ, but gut microbiomes from urinary tract colonized patients were elevated in E.coli abundance 7-14 days post-antimicrobial treatment. Corresponding UPEC gut isolates from urinary tract colonizing lineages showed elevated phenotypic resistance against 11 of 23 tested drugs compared to non-colonizing lineages. The gut microbiome is implicated in UPEC urinary tract colonization during rUTI, serving as an ARG-enriched reservoir for UPEC. UPEC can asymptomatically colonize the gut and urinary tract, and post-antimicrobial blooms of gut E.coli among urinary tract colonized patients suggest that cross-habitat migration of UPEC is an important mechanism of rUTI. Thus, treatment duration and UPEC populations in both the urinary and gastrointestinal tract should be considered in treating rUTI and developing novel therapeutics.

Stepping into the future of behavioral health: Opportunities, challenges, and possibilities.

To improve our practices of today and to overcome the problems that confront us at present, the behavioral health field must anticipate what the future is likely to bring. Such foresight is particularly important right now because of the changes and disruptions that have occurred due to the COVID-19 pandemic over the past 3 years. We begin by recounting major developments in the mental health field since the founding of the National Institute of Mental Health (NIMH) more than 70 years ago, including some firsthand experiences of the senior author. Subsequently, we review the present situation of the behavioral health field with particular attention to the effects of COVID-19 and our current workforce crisis. Likely future scenarios are then described in two principal domains: clinical developments and community developments. Clinical developments over the next decade are likely to include much more self-directed, integrated, virtual, and personalized care. Community developments are likely to include self-empowering community interventions, better population health management, new collaborations with public health, and continued efforts to address stigma. To increase the probability of the future described, several facilitators are also outlined to create the conditions under which expected future developments can be expected to flourish. These include addressing the behavioral health workforce crisis, modernizing behavioral health clinical training, fostering opportunities for cross-sector work, fostering opportunities to engage in policy issues, creating centers of excellence for innovation in behavioral health, and fostering an integrated framework that undergirds behavioral health. The future we have described holds considerable promise for the behavioral health field and for all who suffer from mental or substance use conditions. We must begin working today to turn this potential future into tomorrow's reality. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Can coaching bridge the gap for incoming Latinx graduate students?

ABSTRACT Attrition rates in the first two years of graduate school are high and ∼50% higher for underrepresented students. Here we evaluate an online group coaching intervention using a controlled and an experimental group to determine its impact on skills that are likely predictors of student success, namely the Hallmark of Success indices developed by the National Institutes of Health (NIH). Our intervention includes eight online coaching sessions (four prior to the first year of graduate school and four during the first year of graduate school). Coaching group sessions, led by certified coaches, address Resilience, Risk and Protective Factors, Accountability, Leadership, Teamwork, Professional Networking, and Self-Assessment. We evaluated the change in Hallmark of Success indices with a pre- and post-questionnaire of 44 items used to assess students’ self-evaluation in nine areas. Students in the experimental coaching group showed a significant increase in the Hallmark of Success indices in seven out of nine areas of student performance between the pre- and post-questionnaires compared to the null model of no changes between time periods. In addition, in all of the nine indices of success, we noted significant differences between the pre- and post-surveys for the experimental group. Our experimental design shows that our cost-effective coaching model improves student performance as perceived by the students.

The National Institutes of Health Lasker Clinical Research Scholars Program: A Decade of Launching Clinician-Scientist Careers.

In response to the decades-long decrease in U.S. clinician-scientists, the National Institutes of Health (NIH) and the Albert and Mary Lasker Foundation launched the Lasker Clinical Research Scholars Program in academic year 2011 to 2012. The investigators examined the early outcomes of this program. Thirty-nine scholars have matriculated into the program as of May 2023. Productivity was assessed for all scholars who joined the program before October 2020 (n = 31). Extramural early-stage investigators (ESIs) were used as a control group, and coarsened exact matching was used to compare the groups. The scholars were compared with the matched ESIs on 4 productivity metrics: publication count, weighted relative citation ratio, clinical impact, and approximate potential to translate. Publication records for both groups were compiled using the NIH Office of Portfolio Analysis' name disambiguation method and manually curated to ensure integrity of the data set. Of the 39 scholars, 29 were compared with 121 matched extramural ESIs. Five years before matriculation, the 2 groups had comparable numbers of publications, but scholars had a higher median weighted relative citation ratio, clinical impact, and approximate potential to translate score. Five years after matriculation, the scholars had a higher median number of publications than the ESIs, and the gap between scholars and ESIs, with scholars having higher scores, had widened for all metrics except approximate potential to translate scores. Of 10 of the 39 scholars at or approaching tenure eligibility, 6 have attained tenure (3 at NIH and 3 in academic institutions), and 4 are on track to attain tenure at NIH. All the Lasker clinical research scholars are substantially involved in clinical and translational research. Their productivity matches or exceeds that of a matched cohort of ESIs at U.S. academic institutions.

Stress and Psychosocial Distress Scale with Blunted Oscillatory Dynamics Serving Abstract Reasoning

Background. Chronic stress is associated with a multitude of psychopathological disorders that share similar alterations in neural dynamics and symptomatology. Applying the National Institute of Mental Health’s Research Domain Criteria (RDoC) framework, we probed the stress-diathesis model by identifying how a transdiagnostic psychosocial distress index representing high-dimensional patterns of stress-related aberrations was coupled to the neural oscillatory dynamics serving abstract reasoning. Methods. The sample consisted of 69 adults (mean age=44.77 years, SD=13.66) who completed the NIH Toolbox Emotion Battery (NIHTB-EB) and a matrix reasoning task during magnetoencephalography (MEG). A transdiagnostic psychosocial distress index was computed using exploratory factor analysis with assessments from the NIHTB-EB. Whole-brain correlations were conducted using the resulting psychosocial distress index for each oscillatory response, and the resulting peak voxels were extracted for mediation analyses to assess the degree to which neural oscillatory activity mediates the interplay between perceived stress and psychosocial distress. Results. We found that elevated psychosocial distress was associated with blunted oscillatory alpha/beta and gamma responses in key cortical association regions. Further, we found that only alpha/beta activity in the right superior temporal sulcus partially mediated the relationship between perceived stress and psychosocial distress. Conclusions. The present study is among the first to couple perceived stress and psychosocial distress with alterations in oscillatory activity during a matrix reasoning task. These findings illuminate the relationship between perceived stress and neural alterations associated with psychopathology.

Current state of the treatment problem in the patients with elbow joint contractures due to ossification

Introduction Surgical treatment of stiff elbow caused by ossification often result in poor outcomes due to anatomical and physiological characteristics, significant functional load and higher patient requirements for the elbow functionality.The purpose was to determine ways of improved surgical treatment for patients with elbow contractures caused by ossification, based on an analysis of literature reporting surgical strategy and outcomes.Material and methods An internet search of PubMed, Medline, Elibrary.ru, CyberLeninka, Google Scholar, International Clinical Trials Registry of the US National Institutes of Health, ISRCTN Registry of International Standard Randomized Clinical Trial Numbers, German Clinical Trials Registry DRKS, WHO Registry was performed. Search words and phrases included elbow contracture, ossification, surgical treatment, stiff, elbow, surgical treatment, ossification. The search depth was 10 years.Results and discussion Some important parameters (recurrence of stiffness, pain, decreased quality of life, etc.) are reported as “very unassertive” in patients with stiff elbow due to ossification at mid and long terms (12–24 months or greater). Poor outcomes are reported in approximately 50 % of the cases due to the range of motion decreased to the preoperative level or less. Many patients (more than 90 % according to some authors) need a repeated surgery and are at risk for the stiff joint.Conclusion A critical analysis of the literature indicates lack of preoperative instrumentation examination of patients with use of new visualization methods (3D modeling). Preoperative examination and surgical planning based on additive technologies are essential for surgically treated patients with stiff elbow caused by ossification.

Mapping of Alzheimer’s disease related data elements and the NIH Common Data Elements

BackgroundAlzheimer’s Disease (AD) is a devastating disease that destroys memory and other cognitive functions. There has been an increasing research effort to prevent and treat AD. In the US, two major data sharing resources for AD research are the National Alzheimer’s Coordinating Center (NACC) and the Alzheimer’s Disease Neuroimaging Initiative (ADNI); Additionally, the National Institutes of Health (NIH) Common Data Elements (CDE) Repository has been developed to facilitate data sharing and improve the interoperability among data sets in various disease research areas.MethodTo better understand how AD-related data elements in these resources are interoperable with each other, we leverage different representation models to map data elements from different resources: NACC to ADNI, NACC to NIH CDE, and ADNI to NIH CDE. We explore bag-of-words based and word embeddings based models (Word2Vec and BioWordVec) to perform the data element mappings in these resources.ResultsThe data dictionaries downloaded on November 23, 2021 contain 1,195 data elements in NACC, 13,918 in ADNI, and 27,213 in NIH CDE Repository. Data element preprocessing reduced the numbers of NACC and ADNI data elements for mapping to 1,099 and 7,584 respectively. Manual evaluation of the mapping results showed that the bag-of-words based approach achieved the best precision, while the BioWordVec based approach attained the best recall. In total, the three approaches mapped 175 out of 1,099 (15.92%) NACC data elements to ADNI; 107 out of 1,099 (9.74%) NACC data elements to NIH CDE; and 171 out of 7,584 (2.25%) ADNI data elements to NIH CDE.ConclusionsThe bag-of-words based and word embeddings based approaches showed promise in mapping AD-related data elements between different resources. Although the mapping approaches need further improvement, our result indicates that there is a critical need to standardize CDEs across these valuable AD research resources in order to maximize the discoveries regarding AD pathophysiology, diagnosis, and treatment that can be gleaned from them.

Research ethics and artificial intelligence for global health: perspectives from the global forum on bioethics in research

BackgroundThe ethical governance of Artificial Intelligence (AI) in health care and public health continues to be an urgent issue for attention in policy, research, and practice. In this paper we report on central themes related to challenges and strategies for promoting ethics in research involving AI in global health, arising from the Global Forum on Bioethics in Research (GFBR), held in Cape Town, South Africa in November 2022.MethodsThe GFBR is an annual meeting organized by the World Health Organization and supported by the Wellcome Trust, the US National Institutes of Health, the UK Medical Research Council (MRC) and the South African MRC. The forum aims to bring together ethicists, researchers, policymakers, research ethics committee members and other actors to engage with challenges and opportunities specifically related to research ethics. In 2022 the focus of the GFBR was “Ethics of AI in Global Health Research”. The forum consisted of 6 case study presentations, 16 governance presentations, and a series of small group and large group discussions. A total of 87 participants attended the forum from 31 countries around the world, representing disciplines of bioethics, AI, health policy, health professional practice, research funding, and bioinformatics. In this paper, we highlight central insights arising from GFBR 2022.ResultsWe describe the significance of four thematic insights arising from the forum: (1) Appropriateness of building AI, (2) Transferability of AI systems, (3) Accountability for AI decision-making and outcomes, and (4) Individual consent. We then describe eight recommendations for governance leaders to enhance the ethical governance of AI in global health research, addressing issues such as AI impact assessments, environmental values, and fair partnerships.ConclusionsThe 2022 Global Forum on Bioethics in Research illustrated several innovations in ethical governance of AI for global health research, as well as several areas in need of urgent attention internationally. This summary is intended to inform international and domestic efforts to strengthen research ethics and support the evolution of governance leadership to meet the demands of AI in global health research.

Historical technology transfer activities and productivity of NIDLRR grantees

ABSTRACT This paper analyzes the technology-related outputs from The National Institute of Disability, Independent Living, and Rehabilitation Research (NIDILRR). We seek to answer the questions: What are the types and frequency of assistive technology (AT) technology transfer (ATTT) outputs from NIDILRR grants? How does NIDILRR’s ATTT generation compare to other granting organizations? What types of ATTT outputs occur, how, and what is the relative productivity of the most frequently funded universities and small businesses performing with funding by NIDILRR grants? An online search was conducted for indications of ATTT from grants funded from 1983–2021 through publicly available databases, the National Rehabilitation Information Center (NARIC), and the internet. This data was then categorized across relevant output types and analyzed. NIDILRR funded 662 organizations and 951 different investigators from 1983 to 2021. The NIDILRR-funded portfolio includes 6,996 papers, 438 informational websites, 163 patents, 120 software products, and 29 hardware products. Compared to the National Institutes of Health (NIH), NIDILRR produced slightly more products per dollar. Our results highlight the substantial portfolio of technology-related outputs generated with NIDILRR funding and demonstrate how productivity measures can be calculated to guide future funding strategies.

Gonadotropin-Releasing Hormone (GnRH) Agonists Do Not Protect Ovarian Function in Patients Undergoing Stem Cell Transplants.

Introduction Medical indications for fertility preservation include any malignancy, chronic illness, or disease that would require gonadotoxic chemotherapy or radiation (conditioning regimens), which would impede a woman's ability to conceive in the future. Thus, any patient who plans to undergo a gonadotoxic regimen is advised to cryopreserve oocytes or embryos, which can be used in the future at the patient's convenience. Attempts have been made to suppress ovarian function with gonadotropin-releasing hormone agonists (GnRH-a) to induce ovarian quiescence and, thereby, theoretically limit the gonadotoxicimpact onthe follicular pool. We explored the use of leuprolide (a type of GnRH-a) inpreventing primary ovarian insufficiency (POI) in a cohort study of patients who underwent hematopoietic stem cell transplants (HSCT) at the National Institutes of Health(NIH); since the conditioning regimens for HSCT include cyclophosphamide and other gonadotoxic therapies, we hypothesized that GnRH-a would be ineffective in preventing POI. Methods We assessedpatients who underwent fertility preservation prior to their stem cell transplant, as their follicular-stimulating hormone(FSH) levels were evaluated prior to and post-chemotherapy. Twenty-nine patients who underwent hormonal evaluation prior to and post-chemotherapy were included. The control group did not receive GnRH-a prior to chemotherapy, while the treatment group did receive GnRH-a pre-chemotherapy. Results Our data revealed that 80% of the control group had menopausal levels post-chemotherapy, while 91% of the treatment group still had menopausal levels post-chemotherapy (p=0.33). Conclusions Thus, our hypothesis that GnRH-a is ineffective in reducing the risk of POI in a cohort of patients who receive conditioning regimens for HSCT was confirmed.

MAPT H2 haplotype and risk of Pick's disease in the Pick's disease International Consortium: a genetic association study

Pick's disease is a rare and predominantly sporadic form of frontotemporal dementia that is classified as a primary tauopathy. Pick's disease is pathologically defined by the presence in the frontal and temporal lobes of Pick bodies, composed of hyperphosphorylated, three-repeat tau protein, encoded by the MAPT gene. MAPT has two distinct haplotypes, H1 and H2; the MAPT H1 haplotype is the major genetic risk factor for four-repeat tauopathies (eg, progressive supranuclear palsy and corticobasal degeneration), and the MAPT H2 haplotype is protective for these disorders. The primary aim of this study was to evaluate the association of MAPT H2 with Pick's disease risk, age at onset, and disease duration. In this genetic association study, we used data from the Pick's disease International Consortium, which we established to enable collection of data from individuals with pathologically confirmed Pick's disease worldwide. For this analysis, we collected brain samples from individuals with pathologically confirmed Pick's disease from 35 sites (brainbanks and hospitals) in North America, Europe, and Australia between Jan 1, 2020, and Jan 31, 2023. Neurologically healthy controls were recruited from the Mayo Clinic (FL, USA, or MN, USA between March 1, 1998, and Sept 1, 2019). For the primary analysis, individuals were directly genotyped for the MAPT H1-H2 haplotype-defining variant rs8070723. In a secondary analysis, we genotyped and constructed the six-variant-defined (rs1467967-rs242557-rs3785883-rs2471738-rs8070723-rs7521) MAPT H1 subhaplotypes. Associations of MAPT variants and MAPT haplotypes with Pick's disease risk, age at onset, and disease duration were examined using logistic and linear regression models; odds ratios (ORs) and β coefficients were estimated and correspond to each additional minor allele or each additional copy of the given haplotype. We obtained brain samples from 338 people with pathologically confirmed Pick's disease (205 [61%] male and 133 [39%] female; 338 [100%] White) and 1312 neurologically healthy controls (611 [47%] male and 701 [53%] female; 1312 [100%] White). The MAPT H2 haplotype was associated with increased risk of Pick's disease compared with the H1 haplotype (OR 1·35 [95% CI 1·12 to 1·64], p=0·0021). MAPT H2 was not associated with age at onset (β -0·54 [95% CI -1·94 to 0·87], p=0·45) or disease duration (β 0·05 [-0·06 to 0·16], p=0·35). Although not significant after correcting for multiple testing, associations were observed at p less than 0·05: with risk of Pick's disease for the H1f subhaplotype (OR 0·11 [0·01 to 0·99], p=0·049); with age at onset for H1b (β 2·66 [0·63 to 4·70], p=0·011), H1i (β -3·66 [-6·83 to -0·48], p=0·025), and H1u (β -5·25 [-10·42 to -0·07], p=0·048); and with disease duration for H1x (β -0·57 [-1·07 to -0·07], p=0·026). The Pick's disease International Consortium provides an opportunity to do large studies to enhance our understanding of the pathobiology of Pick's disease. This study shows that, in contrast to the decreased risk of four-repeat tauopathies, the MAPT H2 haplotype is associated with an increased risk of Pick's disease in people of European ancestry. This finding could inform development of isoform-related therapeutics for tauopathies.

Parameters That Can Be Used to Quantify Reduction Accuracy in Talar Neck Fractures and Malunions: A PRISMA-Compliant Scoping Review and Meta-Analysis.

Understanding the three-dimensional anatomy of the talar neck is essential in assessing the accuracy of reduction in talar neck fractures as well as for planning surgical correction for talar malunions. However, the geometrical parameters that describe this anatomy are sparsely reported in the orthopedics literature. We aimed to identify from the existing literature, geometrical parameters that describe the anatomy of the talar neck, determine how these are measured, and their normative values. A scoping literature review was conducted in accordance with thePreferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)extension for scoping reviews (PRISMA-ScR) guidelines. The primary searches were conducted on the PubMed, Embase, and Scopus databases. Any original research study looking at the human talus neck geometry was included. Parameters that described the anatomy of the talar neck were identified, andpooled estimates were determined by the random-effects meta-analysis model. Heterogeneity was assessed by the I2 test and leave-one-out meta-analysis. Subgroup analysis was done to compare the values of parameters between the Asian and Non-Asian populations. The risk of bias was assessed by the National Institutes of Health (NIH) Case Series Tool. The combined searches yielded 6326 results, of which 21 studies were included in the review and 15 in six different sets of metanalysis. The majority of the studies (n=19, 90.5%) evaluated adult tali, and only two (9.5%) evaluated pediatric tali.In most of the studies (n=13, 61.9%), talus neck geometry was evaluated on dry bones or anatomical specimens; evaluation by imaging techniques (radiographs, CT, MRI, and radiostereometric analysis) was used in eight studies, (39.1%). A total of eight different geometrical parameters (neck length, height, width, declination angle, inclination angle, torsion angle, circumference, and cross-sectional area) were identified. Except for talar torsion, variability was noted in methods of measurement of all other parameters. Subgroup analysis revealed that Asians had a higher neck height as compared to non-Asians; other parameters were not significantly different. Although the literature reports geometrical parameters to assess the talar geometry, the methods of measurement of these parameters are variable. Most of the available literature describes measurement techniques on cadaveric tali, and there is no literature on how these parameters should be measured on conventional CT or MRI slices. Further research needs to focus on the standardization of measurement techniques for these parameters on conventional CT and/or MRI scans.

Resources Utilized by Otolaryngology Fellowship Directors When Determining Reputations of Residency Programs.

Residency program reputation is consistently reported as an important factor by fellowship directors when considering applicants. This study sets out to determine resources fellowship directors rely on when determining residency program reputation. Cross-sectional study. Using an anonymous online survey of all 2022 Otolaryngology (OHNS) fellowship program directors. The 13-question survey sought to assess fellowship director's perspectives and resource utilization when determining residency program reputation. Representing all OHNS fellowship program directors and co-directors (N = 287), 103 responded to our survey, response rate 35.9%. Most participants reported that residency reputation was important for fellowship candidacy. On a Likert scale of 1 to 5, 1 being most important and 5 being not important, personal knowledge of the residency program (2.03 out of 5) and program faculty/mentor reputation (2.09 out of 5) were the most important factors cited. 63% were unfamiliar with the survey methodology of Doximity Residency Navigator (DRN), while 53% contributed to DRN by filling out surveys. Nearly all fellowship directors (N = 100, 97%) reported their rank list was not influenced by DRN. Most fellowship directors reported that US News and World Report (USNWR) and DRN were neither consistent nor inconsistent with their perceptions of residency reputations (38% and 56%, respectively), suggesting ambivalence toward these resources. Residency reputation is important for fellowship directors when evaluating fellowship candidates. Directors do not rely on USNWR, National Institute of Health (NIH) ranking, or DRN when gauging residency reputation, but rather personal knowledge of the applicant's residency program or reputation of the otolaryngology faculty.

Efficacy of assisted partner services for people who inject drugs in Kenya to identify partners living with HIV and hepatitis C virus infection: a prospective cohort study

People who inject drugs are at increased risk of both HIV and hepatitis C virus (HCV) infections but face barriers to testing and engagement in care. Assisted partner services are effective in locating people with HIV but are understudied among people who inject drugs. We assessed whether assisted partner services could be used to find, test for HIV and HCV infections, and link to care the partners of people who inject drugs in Kenya. In this prospective study at eight sites offering harm-reduction services in Kenya, we enrolled people aged 18 years or older who inject drugs and were living with HIV (index participants) between Feb 27, 2018, and Nov 1, 2021. Index participants provided information about their sexual and injecting partners (ie, anyone with whom they had had sexual intercourse or injected drugs in the previous 3 years), and then community-embedded peer educators located partners and referred them for enrolment in the study (partner participants). All participants underwent testing for HCV infection, and partner participants also underwent HIV testing. Index and partner participants with HIV but who were not on antiretroviral therapy (ART) were linked with treatment services, and those positive for HCV were linked to treatment with direct-acting antivirals. We calculated the number of index participants whom we needed to interview to identify partner participants with HIV and HCV infection. We enrolled 989 people living with HIV who inject drugs, who mentioned 4705 sexual or injecting partners. Of these 4705 partners, we enrolled 4597 participants, corresponding to 3323 unique individuals. 597 (18%) partner participants had HIV, of whom 506 (85%) already knew their status. 358 (71%) of those who knew they were HIV positive were virally suppressed. 393 (12%) partner participants were HCV antibody positive, 213 (54%) of whom had viraemia and 104 (26%) of whom knew their antibody status. 1·66 (95% CI 1·53-1·80) index participants had to be interviewed to identify a partner with HIV, and 4·24 (3·75-4·85) had to be interviewed to find a partner living with HIV who was unaware of their HIV status, not on ART, or not virally suppressed. To find a partner seropositive for HCV who did not know their antibody status, 3·47 (3·11-3·91) index participants needed to be interviewed. Among the 331 index and partner participants living with HIV who were not on ART at enrolment, 238 (72%) were taking ART at 6-month follow-up. No adverse events were attributed to study procedures. Use of assisted partner services among people with HIV who inject drugs was safe and identified partners with HIV and HCV infections. Assisted partner services was associated with increased uptake of ART for both index participants and partners. US National Institutes of Health.

Cooking with liquefied petroleum gas or biomass and fetal growth outcomes: a multi-country randomised controlled trial

Household air pollution might lead to fetal growth restriction during pregnancy. We aimed to investigate whether a liquefied petroleum gas (LPG) intervention to reduce personal exposures to household air pollution during pregnancy would alter fetal growth. The Household Air Pollution Intervention Network (HAPIN) trial was an open-label randomised controlled trial conducted in ten resource-limited settings across Guatemala, India, Peru, and Rwanda. Pregnant women aged 18-34 years (9-19 weeks of gestation) were randomly assigned in a 1:1 ratio to receive an LPG stove, continuous fuel delivery, and behavioural messaging or to continue usual cooking with biomass for 18 months. We conducted ultrasound assessments at baseline, 24-28 weeks of gestation (the first pregnancy visit), and 32-36 weeks of gestation (the second pregnancy visit), to measure fetal size; we monitored 24 h personal exposures to household air pollutants during these visits; and we weighed children at birth. We conducted intention-to-treat analyses to estimate differences in fetal size between the intervention and control group, and exposure-response analyses to identify associations between household air pollutants and fetal size. This trial is registered with ClinicalTrials.gov (NCT02944682). Between May 7, 2018, and Feb 29, 2020, we randomly assigned 3200 pregnant women (1593 to the intervention group and 1607 to the control group). The mean gestational age was 14·5 (SD 3·0) weeks and mean maternal age was 25·6 (4·5) years. We obtained ultrasound assessments in 3147 (98·3%) women at baseline, 3052 (95·4%) women at the first pregnancy visit, and 2962 (92·6%) at the second pregnancy visit, through to Aug 25, 2020. Intervention adherence was high (the median proportion of days with biomass stove use was 0·0%, IQR 0·0-1·6) and pregnant women in the intervention group had lower mean exposures to particulate matter with a diameter less than 2·5 μm (PM2·5; 35·0 [SD 37·2] μg/m3vs 103·3 [97·9] μg/m3) than did women in the control group. We did not find differences in averaged post-randomisation Z scores for head circumference (0·30 vs 0·39; p=0·04), abdominal circumference (0·38 vs 0·39; p=0·99), femur length (0·44 vs 0·45; p=0·73), and estimated fetal weight or birthweight (-0·13 vs -0·12; p=0·70) between the intervention and control groups. Personal exposures to household air pollutants were not associated with fetal size. Although an LPG cooking intervention successfully reduced personal exposure to air pollution during pregnancy, it did not affect fetal size. Our findings do not support the use of unvented liquefied petroleum gas stoves as a strategy to increase fetal growth in settings were biomass fuels are used predominantly for cooking.

Parkinson's Disease Psychosis and the Marketing of Pimavanserin.

In 2016, Nuplazid (pimavanserin) became the first FDA-approved treatment for Parkinson's Disease Psychosis (PDP). We explored the possibility that PDP was a term created to market Nuplazid. We examined trends in perceptions of psychosis in Parkinson's disease from the 1990s to 2020 through MEDLINE search term frequency, neurology textbooks, guidance from professional societies, Acadia annual reports, sponsored websites, and a sponsored meeting held by the National Institutes of Health (NIH). We analyzed continuing medical education (CME) activities on PDP and analyzed the connection between payments by the manufacturer of pimavanserin and prescriptions. Our analysis of nine sponsored CME activities reveals misleading themes, including: PDP is common, progressive, and not always drug-induced; there is no such thing as a benign hallucination, and psychotic symptoms always worsen; PDP increases mortality; and competing treatments are ineffective or dangerous while pimavanserin is safe and effective for treating PDP. Industry-sponsored CME was used to disseminate inaccurate and misleading marketing messages on psychosis related to Parkinson's disease. Some professional societies and some textbooks also resisted the PDP label. Reframing PDP as a unique condition is a typical example of condition branding. The establishment of PDP expanded the use of pimavanserin and is likely to have resulted in many avoidable deaths.

Systematic Review of Heel Puncture-Related Osteomyelitis of the Calcaneus in Newborn Infants.

Heel puncture (HP) in neonates can result in osteomyelitis if done non-aseptically or with incorrect technique. This study summarizes clinical experience with heel puncture-related osteomyelitis of the calcaneus (HP-CO) in newborns. We systematically reviewed studies that examined HP-CO in newborn patients using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Our search included the PubMed, Embase, and Cochrane Library databases until December 31, 2023. We used the National Institutes of Health (NIH) assessment scale to evaluate the quality of our analyzed studies. This study analyzed 15 neonatal calcaneal osteomyelitis (CO) cases due to HP conducted in six countries from 1976 to 2016. The average age of the cases was 8.87 ± 6.13days, with an average birth weight of 2367.27 ± 947.59g. The infants had undergone an average of 9.00 ± 8.90 HP, with 93.33% exhibiting swelling. Staphylococcus aureus was present in 80% of cases. Beta-lactam antibiotics were used, with satisfactory outcomes in 53.33% of cases. However, in seven cases, three patients had flatfoot due to calcaneal deformity, and other complications were observed in some patients after 7-8years. This study offers valuable insights into a rare condition, including its epidemiology, clinical and laboratory characteristics, and treatment options for infants with HP-CO. To prevent the risk of osteomyelitis in this vulnerable group of patients, increasing awareness and maintaining strict aseptic techniques is necessary. We recommend that infants presenting with tenderness, redness, purulent discharge, erythema, or fever and with a history of repeated HP and swollen ankles should be evaluated for suspicion of osteomyelitis.

Demographic and clinical features of dengue fever infection in Pakistan: a cross-sectional epidemiological study

BackgroundDengue fever caused by dengue virus is a tropical disease and is among the deadliest vector-borne diseases. The humid and hot summers of Pakistan support the probation of the vectors responsible for the transmission of viral and other parasitic diseases.MethodologyA retrospective study, from 2012- 2019, of dengue infected individuals from the Punjab province of Pakistan was carried out to analyze epidemiology, clinical and laboratory findings of subjects with dengue virus infection. Data was derived from National Institute of Health (NIH) followed by Dengue control program of Pakistan, covering the incidence rate in 36 districts of Punjab and Islamabad Capital Territory (ICT) respectively. Patients data including the presence of dengue specific antigen or/and antibodies such as NS1 and IgG/IgM were observed. The study also included the analysis of demographic data, geographic data, and the month-wise distribution of dengue cases to examine seasonal trends.ResultsWe analyzed 25,682 dengue infected individuals. The statistical analysis revealed a significant association between genders in which male population was more affected by dengue than females. It was also noted that the middle age group was the most affected age group while the highest number of cases were reported in October. Rawalpindi and Lahore were the most affected cities in Punjab province while Islamabad represented the highest number of cases during the recent outbreak in 2019. The IgM and IgG antibodies were highly prevalent among the infected patients.ConclusionDengue is endemic in Pakistan, circulating throughout the year. Highest number of cases were observed in the month of October, September and November respectively. Association between climate change and vector-borne diseases need to be investigated in Pakistan as they significantly influence the timing and intensity of dengue and other disease outbreaks. Further exploration of hematological parameters is required to better diagnose and treat the disease. For the effective control of dengue outbreaks, awareness campaigns on sewage management and vector control along with social factors are strongly recommended for better control and eradication of the disease.
