Abiraterone-Associated Mineralocorticoid Excess: A Case Report.

Abiraterone acetate causes an adrenocorticotropic hormone (ACTH)-mediated mineralocorticoid excess. We present a 77-year-old man with prostate adenocarcinoma who developed signs and symptoms of mineralocorticoid excess while on abiraterone and discuss its pathophysiology and treatment options. The patient developed hypokalemia, metabolic alkalosis, and hypertension, indicative of increased mineralocorticoid activity, confirmed by elevated ACTH, corticosterone, and deoxycorticosterone levels. Abiraterone inhibits cytochrome P450c17 (CYP17A1), thus inhibiting testosterone and cortisol synthesis. Diminished cortisol synthesis, in turn, leads to excessive mineralocorticoid precursor production mediated by ACTH, leading to enhanced sodium absorption and potassium excretion. Abiraterone is often prescribed with low-dose prednisone to suppress ACTH; however, this strategy may not provide physiological glucocorticoid levels, resulting in ACTH-mediated mineralocorticoid excess in some patients. High-dose steroids or mineralocorticoid antagonists may activate mutant androgen receptors in prostate cancer tissue; therefore, amiloride is suggested for managing residual mineralocorticoid activity. This case highlights the importance of being vigilant for the signs and symptoms of mineralocorticoid excess in patients on abiraterone.

The Association of Polycystic Ovarian Syndrome Among Reproductive-Aged Women With Consumption of Junk Food in Jeddah, Saudi Arabia.

OBJECTIVE: Polycystic ovarian syndrome (PCOS) is a common reproductive and endocrinological disorder that affects a significant percentage of women worldwide. Despite its high prevalence, the possible environmental factors that influence the development of PCOS, especially dietary habits, are still unclear. The aim of this study is to investigate the association between PCOS and junk food consumption among women of childbearing age in Jeddah, Saudi Arabia. METHODS: A cross-sectional study was conducted from February 2023 to April 2023 in 155 women diagnosed with PCOS according to the Rotterdam criteria. Participants aged 18-47 years and living in Jeddah, Saudi Arabia completed a validated 30-item electronic questionnaire that included sociodemographic information, medical history, PCOS symptoms, and fast food consumption patterns. RESULTS: The study revealed a high prevalence of obesity and overweight among PCOS patients, which was significantly associated with their diets high in carbohydrates, fats, and refined sugars. In addition, weight loss was difficult for these patients, which could be influenced by hormonal imbalances and dietary factors. In particular, fast food consumption showed a significant association with facial acne in PCOS patients, while some participants also experienced excessive hair growth on the face, abdomen, and back, which may be related to excessive fat intake. CONCLUSION: This study provides evidence to support an association between junk food consumption and the prevalence of PCOS among women of reproductive age in Jeddah, Saudi Arabia. The findings suggest that dietary patterns may influence the development and treatment of PCOS, highlighting the need for lifestyle interventions as part of treatment strategies. Further studies with larger and more diverse populations, as well as longitudinal studies, are warranted to clarify causal relationships and gain a comprehensive understanding of the impact of dietary factors on the development and progression of PCOS. Identifying the potential effects of diet on PCOS can lead to more effective treatments and improve the overall health and well-being of those affected.

Identifying patients at increased risk of non-ventilator-associated pneumonia on admission to hospital: a pragmatic prognostic screening tool to trigger preventative action.

BACKGROUND: Non-ventilator healthcare-associated pneumonia (NV-HAP) is an important healthcare-associated infection. This study tested the feasibility of using routine admission data to identify those patients at high risk of NV-HAP who could benefit from targeted, preventive interventions. METHODS: Patients aged ≥64 years who developed NV-HAP five days or more after admission to elderly-care wards, were identified by retrospective case note review together with matched controls. Data on potential predictors of NV-HAP were captured from admission records. Multi-variate analysis was used to build a prognostic screening tool (PRHAPs); acceptability and feasibility of the tool was evaluated. RESULTS: A total of 382 cases/381 control patients were included in the analysis. Ten predictors were included in the final model; nine increased the risk of NV-HAP (OR between 1.68 and 2.42) and one (independent mobility) was protective (OR 0.48; 95% CI 0.30-0.75). The model correctly predicted 68% of the patients with and without NV-HAP; sensitivity 77%; specificity 61%. The PRHAPs tool risk score was 60% or more if two predictors were present and over 70% if three were present. An expert consensus group supported incorporating the PRHAPs tool into electronic logic systems as an efficient mechanism to identify patients at risk of NV-HAP and target preventative strategies. CONCLUSIONS: This prognostic screening (PRHAPs) tool, applied to data routinely collected when a patient is admitted to hospital, could enable staff to identify patients at greatest risk of NV-HAP, target scarce resources in implementing a prevention care bundle, and reduce the use of antimicrobial agents.

Evidences for reaction mechanism of 9DB1 DNA catalyst.

The first reported reaction mechanism of a DNAzyme, i.e. 9DB1, by using molecular dynamics (MD) simulations includes some ambiguities. We try to overcome some of these ambiguous aspects such as the role of mono and divalent metal ions and observed metal rescue effects by surveying the role of functional groups of original 9DB1 and a variety of its rate conserving and rate decreasing mutations via MD simulations. Conformational differences of these two distinct groups are responsible for their opposite rate trends. Blocking of the OH3' of acceptor nucleotide from effective attack by its hydrogen bond to O4' of donor nucleotide is observed in rate decreasing mutations. Our simulations manifest the role of Na+ and Mg2+ ions in bringing close to each other the ligated atoms. These findings along with observed conformational changes explain carefully the reported metal rescue effects for some phosphate groups.

Rapid implementation of an emergency on-site CKRT dialysate production system during the COVID-19 pandemic.

BACKGROUND: On December 29, 2021, during the delta wave of the Coronavirus Disease 2019 (COVID-19) pandemic, the stock of premanufactured solutions used for continuous kidney replacement therapy (CKRT) at the University of New Mexico Hospital (UNMH) was nearly exhausted with no resupply anticipated due to supply chain disruptions. Within hours, a backup plan, devised and tested 18 months prior, to locally produce CKRT dialysate was implemented. This report describes the emergency implementation and outcomes of this on-site CKRT dialysate production system. METHODS: This is a single-center retrospective case series and narrative report describing and reporting the outcomes of the implementation of an on-site CKRT dialysate production system. All adults treated with locally produced CKRT dialysate in December 2021 and January 2022 at UNMH were included. CKRT dialysate was produced locally using intermittent hemodialysis machines, hemodialysis concentrate, sterile parenteral nutrition bags, and connectors made of 3-D printed biocompatible rigid material. Outcomes analyzed included dialysate testing for composition and microbiologic contamination, CKRT prescription components, patient mortality, sequential organ failure assessment (SOFA) scores, and catheter-associated bloodstream infections (CLABSIs). RESULTS: Over 13 days, 22 patients were treated with 3,645 L of locally produced dialysate with a mean dose of 20.0 mL/kg/h. Fluid sample testing at 48 h revealed appropriate electrolyte composition and endotoxin levels and bacterial colony counts at or below the lower limit of detection. No CLABSIs occurred within 7 days of exposure to locally produced dialysate. In-hospital mortality was 81.8% and 28-day mortality was 68.2%, though illness severity was high, with a mean SOFA score of 14.5. CONCLUSIONS: Though producing CKRT fluid with IHD machines is not novel, this report represents the first description of the rapid and successful implementation of a backup plan for local CKRT dialysate production at a large academic medical center in the U.S. during the COVID-19 pandemic. Though conclusions are limited by the retrospective design and limited sample size of our analysis, our experience could serve as a guide for other centers navigating similar severe supply constraints in the future.

Evaluating the cost implications of integrating SARS-CoV-2 genome sequencing for infection prevention and control investigation of nosocomial transmission within hospitals.

BACKGROUND: The COG-UK hospital-onset COVID-19 infection (HOCI) trial evaluated the impact of SARS-CoV-2 whole-genome sequencing (WGS) on acute infection, prevention, and control (IPC) investigation of nosocomial transmission within hospitals. AIM: To estimate the cost implications of using the information from the sequencing reporting tool (SRT), used to determine likelihood of nosocomial infection in IPC practice. METHODS: A micro-costing approach for SARS-CoV-2 WGS was conducted. Data on IPC management resource use and costs were collected from interviews with IPC teams from 14 participating sites and used to assign cost estimates for IPC activities as collected in the trial. Activities included IPC-specific actions following a suspicion of healthcare-associated infection (HAI) or outbreak, as well as changes to practice following the return of data via SRT. FINDINGS: The mean per-sample costs of SARS-CoV-2 sequencing were estimated at £77.10 for rapid and £66.94 for longer turnaround phases. Over the three-month interventional phases, the total management costs of IPC-defined HAIs and outbreak events across the sites were estimated at £225,070 and £416,447, respectively. The main cost drivers were bed-days lost due to ward closures because of outbreaks, followed by outbreak meetings and bed-days lost due to cohorting contacts. Actioning SRTs, the cost of HAIs increased by £5,178 due to unidentified cases and the cost of outbreaks decreased by £11,246 as SRTs excluded hospital outbreaks. CONCLUSION: Although SARS-CoV-2 WGS adds to the total IPC management cost, additional information provided could balance out the additional cost, depending on identified design improvements and effective deployment.

Proliferative glomerulonephritis with monoclonal immunoglobulin deposits triggered by COVID-19: a case report.

Acute kidney injury (AKI) frequently complicates corona virus disease 2019 (COVID-19) and is associated with significant mortality. Kidney disease in COVID-19 is usually due to acute tubular injury, but a variety of glomerular processes, especially collapsing glomerulopathy, have been increasingly described. Until recently, proliferative glomerulonephritis with monoclonal immunoglobulin deposits (PGNMID) had not been reported in the setting of COVID-19. We present a case of dialysis-dependent AKI developing soon after symptomatic COVID-19 which, on kidney biopsy, was found to be due to PGNMID with IgG3 kappa deposits. As is typical of PGNMID, a search for evidence of extra-renal monoclonal immunoglobulin or clonal lymphocyte population was negative. However, the patient had a favorable response to anti-plasma cell therapy and was ultimately able to stop hemodialysis. Though monoclonal gammopathy of renal significance (MGRS) is usually not associated with infection, other cases of post-viral MGRS, including PGNMID, have been previously reported. PGNMID has recently been linked specifically to COVID-19, with this representing one of only four cases reported thus far. Though causality between the preceding viral infection and the subsequent glomerulonephritis cannot be proven in these reports, nephrologists should be aware that not all kidney disease occurring in the aftermath of COVID-19 is due to tubular injury or collapsing glomerulopathy. As such, kidney biopsy should be routinely considered in the setting of COVID-19-associated glomerular disease as findings may change management. In the case of COVID-19-associated PGNMID data to guide treatment are limited, but our report suggests that anti-plasma cell therapy may be effective.

Comparative brain analysis of wild and hatchery reared Mahseer (Tor putitora) relative to their body weight and length / Análise comparativa do cérebro de Mahseer (Tor putitora) selvagem e criado em incubatório em relação ao peso e comprimento corporal

The present study was aimed at comparing the brain size of mahseer (Tor putitora) in relation to their body weight and standard length, to investigate the potential impact of rearing environment on brain development in fish. The weight of the brain and three of its subdivisions cerebellum (CB), optic tectum (OT), and telencephalon (TC) were measured for both wild and hatchery-reared fish. The data was analysed using multiple analysis of covariance (MANCOVA), analysis of covariance (ANCOVA), and discriminate function analysis (DFA). We found the fish reared under hatchery conditions exhibit smaller brain size related to body weight, when compared to the wild ones. A significant (p<0.5) difference was observed in the length of CB and OT concerning the standard body length while no significant difference was found in TC of the fish from both the origins. The results of the current study highlight a logical assumption that neural deficiency affects the behaviour of fish, that's why the captive-reared fish show maladaptive response and face fitness decline when released to the natural environment for wild stock enhancement. The current study concluded that hatchery-reared fish exhibit variations in gross brain morphology as compared to their wild counterpart.

O presente estudo teve como objetivo comparar o tamanho do cérebro de mahseer (Tor putitora) em relação ao seu peso corporal e comprimento padrão, para investigar o impacto potencial do ambiente de criação no desenvolvimento do cérebro em peixes. O peso do cérebro e três de suas subdivisões ­ cerebelo (CB), tectum óptico (OT) e telencéfalo (TC) ­ foram medidos para peixes selvagens e criados em incubadoras. Os dados foram analisados usando análise múltipla de covariância (MANCOVA), análise de covariância (ANCOVA) e análise de função discriminante (DFA). Descobrimos que os peixes criados em condições de incubação apresentam menor tamanho do cérebro em relação ao peso corporal quando comparados aos selvagens. Uma diferença significativa (p <0,5) foi observada no comprimento do CB e OT em relação ao comprimento corporal padrão, enquanto nenhuma diferença significativa foi encontrada no CT dos peixes de ambas as origens. Os resultados do estudo atual destacam uma suposição lógica de que a deficiência neural afeta o comportamento dos peixes. É por isso que os peixes criados em cativeiro mostram uma resposta mal adaptativa e enfrentam declínio de aptidão quando liberados no ambiente natural para o aprimoramento do estoque selvagem. O estudo atual concluiu que os peixes criados em incubadoras exibem variações na morfologia cerebral bruta em comparação com suas contrapartes selvagens.

Comparative brain analysis of wild and hatchery reared Mahseer (Tor putitora) relative to their body weight and length

Abstract The present study was aimed at comparing the brain size of mahseer (Tor putitora) in relation to their body weight and standard length, to investigate the potential impact of rearing environment on brain development in fish. The weight of the brain and three of its subdivisions cerebellum (CB), optic tectum (OT), and telencephalon (TC) were measured for both wild and hatchery-reared fish. The data was analysed using multiple analysis of covariance (MANCOVA), analysis of covariance (ANCOVA), and discriminate function analysis (DFA). We found the fish reared under hatchery conditions exhibit smaller brain size related to body weight, when compared to the wild ones. A significant (p 0.5) difference was observed in the length of CB and OT concerning the standard body length while no significant difference was found in TC of the fish from both the origins. The results of the current study highlight a logical assumption that neural deficiency affects the behaviour of fish, thats why the captive-reared fish show maladaptive response and face fitness decline when released to the natural environment for wild stock enhancement. The current study concluded that hatchery-reared fish exhibit variations in gross brain morphology as compared to their wild counterpart.

Resumo O presente estudo teve como objetivo comparar o tamanho do cérebro de mahseer (Tor putitora) em relação ao seu peso corporal e comprimento padrão, para investigar o impacto potencial do ambiente de criação no desenvolvimento do cérebro em peixes. O peso do cérebro e três de suas subdivisões cerebelo (CB), tectum óptico (OT) e telencéfalo (TC) foram medidos para peixes selvagens e criados em incubadoras. Os dados foram analisados usando análise múltipla de covariância (MANCOVA), análise de covariância (ANCOVA) e análise de função discriminante (DFA). Descobrimos que os peixes criados em condições de incubação apresentam menor tamanho do cérebro em relação ao peso corporal quando comparados aos selvagens. Uma diferença significativa (p 0,5) foi observada no comprimento do CB e OT em relação ao comprimento corporal padrão, enquanto nenhuma diferença significativa foi encontrada no CT dos peixes de ambas as origens. Os resultados do estudo atual destacam uma suposição lógica de que a deficiência neural afeta o comportamento dos peixes. É por isso que os peixes criados em cativeiro mostram uma resposta mal adaptativa e enfrentam declínio de aptidão quando liberados no ambiente natural para o aprimoramento do estoque selvagem. O estudo atual concluiu que os peixes criados em incubadoras exibem variações na morfologia cerebral bruta em comparação com suas contrapartes selvagens.

Biodiversity of orb-web spiders (family: araneidae) of buner valley, Pakistan

Abstract The present research was carried out to explore the spider fauna of Buner valley with taxonomic study from February 2018 to January 2019. For this purpose samples were collected, four times at each month from 4 tehsils: Daggar, Gagra, Mandan and Totalai. Two methods were used, hand picking and sweep net for collection of samples. During day and night, three habitats, arid area, agriculture land and building area were search for collection. A total of 534 samples of spider were collected from four sampling sites, in which 379 were belonging to family Araniedae. After confirmation, the identified species were belonging to 8 genera (Neoscona, Argiope, Cyclosa, Araneus, Cyrtophora, Larinia, Erivoxia and Poltys) and 19 species. 18 of them were identified to specie level while a single specie to its generic level. The genus Neoscona was the dominant genus 26.31% having 5 species while the genus Argiope 21.05% is the second dominant having 4 species followed by Cyclosa 15.78% having 3 species followed by Cyrtophora and Araneus 10.52% having two species both. The Poltys and Larinia 5.26% are the rarest genera represent single-single specie both. Statistical analysis show that specie richness (D) = 5.77, Simpson index (1-D) = 0.87, Shannon index (H) = 2.33. Diversity of spiders was evenly distributed and calculated Evenness value was H/InS = 0.5408. There is also few atypical species and Fisher alpha estimate high value (Fisher ) = 4.42. Chao-1 estimated we have reported 22 species.

Poltys e Larinia (5,26%) são os gêneros mais raros, representando a mesma espécie. A análise estatística mostrou que a riqueza de espécies (D) foi de 5,77, o índice de Simpson (1-D) foi de 0,87 e o índice de Shannon (H) foi de 2,33. A diversidade de aranhas foi distribuída uniformemente, e o valor calculado da uniformidade foi H / InS = 0,5408. Também existem poucas espécies atípicas, e o alfa de Fisher (Fisher ) estimou o valor de 4,42. Já Chao-1 estimou 22 espécies.

Severe methanol poisoning treated with a novel hemodialysis system: a case report, analysis, and review.

In May and June 2020, an outbreak of methanol poisoning arose in the southwest United States linked to ingestion of contaminated hand sanitizer imported during the coronavirus disease 2019 pandemic, ultimately resulting in over a dozen hospitalizations and at least four deaths in New Mexico and Arizona. In this report, we describe one of these cases in which profound methanol intoxication was successfully treated with the Tablo® Hemodialysis System, the first reported case of toxic alcohol poisoning treated with this novel device. We carry out a formal regression analysis of the serial methanol levels obtained in this case to conservatively estimate that intermittent hemodialysis with Tablo achieved a clearance of methanol of 239 mL/min (95% confidence interval, 173-305 mL/min), a clearance that is well within the previously published standard of care. We conclude by reviewing both the treatment of toxic alcohol poisoning and the determinants of small molecule clearance with hemodialysis, emphasizing the importance of optimizing the dialytic treatment of intoxications with extended treatment times and the use of high-efficiency dialyzers.
