Clinical and demographic features of patients undergoing video-capsule endoscopy management: A descriptive study.

BACKGROUND: Video-capsule endoscopy (VCE) is an efficient tool that has proven to be highly useful in approaching several gastrointestinal diseases. VCE was implemented in Colombia in 2003, however current characterization of patients undergoing VCE in Colombia is limited, and mainly comes from two investigations conducted before the SARS-CoV-2 pandemic period. AIM: To describe the characteristics of patients undergoing VCEs and establish the main indications, findings, technical limitations, and other outstanding features. METHODS: A descriptive study was carried out using data from reports of VCE (PillCam SB3 system) use in a Gastroenterology Unit in Bogotá, Colombia between September 2019 and January 2023. Demographic and clinical variables such as indication for the VCE, gastric and small bowel transit times (GTT, SBTT), endoscopic preparation quality, and limitations were described [n (%), median (IQR)]. RESULTS: A total of 133 VCE reports were analyzed. Most were in men with a median age of 70 years. The majority had good preparation (96.2%), and there were technical limitations in 15.8% of cases. The main indications were unexplained anemia (91%) or occult bleeding (23.3%). The median GTT and SBTT were 14 and 30 minutes, respectively. The frequencies of bleeding stigma (3.79%) and active bleeding (9.09%) were low, and the most frequent abnormal findings were red spots (28.3%), erosions (17.6%), and vascular ectasias (12.5%). CONCLUSION: VCE showed high-level safety. The main indication was unexplained anemia. Active bleeding was the most frequent finding. Combined with artificial intelligence, VCE can improve diagnostic precision and targeted therapeutic interventions.

A new mutation of Sgms1 causes gradual hearing loss associated with a reduced endocochlear potential.

Sgms1 encodes sphingomyelin synthase 1, an enzyme in the sphingosine-1-phosphate signalling pathway, and was previously reported to underlie hearing impairment in the mouse. A new mouse allele, Sgms1tm1a, unexpectedly showed normal Auditory Brainstem Response thresholds. We found that the Sgms1tm1a mutation led to incomplete knockdown of transcript to 20 % of normal values, which was enough to support normal hearing. The Sgms1tm1b allele was generated by knocking out exon 7, leading to a complete lack of detectable transcript in the inner ear. Sgms1tm1b homozygotes showed largely normal auditory brainstem response thresholds at first, followed by progressive loss of sensitivity until they showed severe impairment at 6 months old. The endocochlear potential was consistently reduced in Sgms1tm1b mutants at 3, 4 and 8 weeks old, to around 80 mV compared with around 120 mV in control littermates. The stria vascularis showed a characteristic irregularity of marginal cell surfaces and patchy loss of Kcnq1 expression at their apical membrane, and expression analysis of the lateral wall suggested that marginal cells were the most likely initial site of dysfunction in the mutants. Finally, significant association of auditory thresholds with DNA markers within and close to the human SGMS1 gene were found in the 1958 Birth Cohort, suggesting that SGMS1 variants may play a role in the range of hearing abilities in the human population.

Predictors of outcomes after PCI with incomplete revascularization: Impact of CTO and LAD vessel.

BACKGROUND: Incomplete revascularization (ICR) after percutaneous coronary intervention (PCI) is associated with mortality and morbidity. AIM: We sought to investigate whether ICR in the left anterior descending artery (LAD) is worse than ICR of the right coronary artery (RCA) or left circumflex artery (LCX); and whether ICR in patients with a chronic total occlusion (CTO) is worse than in those without. METHODS: In the RIVER-PCI trial, 2651 patients with ICR after PCI were randomly assigned to ranolazine or placebo. Angiograms were assessed at an independent core laboratory in 2501 patients (94.3%). The primary endpoint was the composite of ischemia-driven revascularization or hospitalization. RESULTS: A total of 1664 patients (66.5%) had ICR involving the LAD, whereas 837 (33.5%) had ICR limited to the RCA or LCX. At median follow-up of 643 days, the primary endpoint occurred in 26.9% versus 26.5% of patients (adjusted HR [aHR]: 1.03, 95% confidence interval [CI]: 0.88-1.21). A nonrecanalized CTO was present in 854 patients (34.1%) with ICR after PCI. The primary endpoint occurred in 28.6% versus 25.9% of ICR patients with versus without a CTO (aHR: 1.10, 95% CI: 0.94-1.29). However, patients with a CTO had higher rates of ischemia-driven hospitalization without revascularization (aHR: 1.27, 95% CI: 1.04-1.56), heart failure hospitalization (aHR: 2.69, 95% CI: 1.61-4.59) and myocardial infarction (aHR: 1.46, 95% CI: 1.11-1.92) compared with those without. CONCLUSIONS: The 2-year prognosis was similar in post-PCI patients with ICR whether the LAD was versus was not involved. ICR patients with a CTO had more frequent hospitalizations for ischemia and myocardial infarctions compared with those without.

Epidemiology of work-related hand and wrist injuries in a referral center: A descriptive study.

BACKGROUND: Occupational hand and wrist injuries (OHWIs) account for 25% of work-related accidents in low- and middle-income countries. In Colombia, more than 500000 occupational accidents occurred in 2021, and although the rate declined to less than 5% in 2020 and 2021, at least one in four accidents involved a hand or wrist injury. AIM: To describe the OHWIs in workers seen at the emergency room at a second-level hospital in Colombia. METHODS: An observational study was performed using data from workers who experienced OHWIs and attended a second-level hospital, between June, 2020 and May, 2021. The overall frequency of OHWIs, as well as their distribution by sociodemographic, clinical, and occupational variables, are described. Furthermore, association patterns between sex, anatomical area (fingers, hand, wrist), and type of job were analyzed by correspondence analysis (CA). RESULTS: There were 2.101 workers treated for occupational accidents, 423 (20.3%) were cases of OHWIs, which mainly affected men (93.9%) with a median age of 31 years and who worked mainly in mining (75.9%). OHWIs were more common in the right upper extremity (55.3%) and comprised different types of injuries, such as contusion (42.1%), laceration (27.9%), fracture (18.7%), and crush injury (15.6%). They primarily affected the phalanges (95.2%), especially those of the first finger (25.7%). The CAs showed associations between the injured anatomical area and the worker's job that differed in men and women (explained variance > 90%). CONCLUSION: One out of five workers who suffered occupational accidents in Cundinamarca, Columbia had an OHWI, affecting mainly males employed in mining. This occupational profile is likely to lead to prolonged rehabilitation, and permanent functional limitations. Our results might be useful for adjusting preventive measures in cluster risk groups.

Steroidogenic Factor-1 Regulation of Dorsomedial Ventromedial Hypothalamic Nucleus Ghrh Neuron Transmitter Marker and Estrogen Receptor Gene Expression in Male Rat.

Ventromedial hypothalamic nucleus (VMN) growth hormone-releasing hormone (Ghrh) neurotransmission shapes counterregulatory hormone secretion. Dorsomedial VMN Ghrh neurons express the metabolic-sensitive transcription factor steroidogenic factor-1/NR5A1 (SF-1). In vivo SF-1 gene knockdown tools were used here to address the premise that in male rats, SF-1 may regulate basal and/or hypoglycemic patterns of Ghrh, co-transmitter biosynthetic enzyme, and estrogen receptor (ER) gene expression in these neurons. Single-cell multiplex qPCR analyses showed that SF-1 regulates basal profiles of mRNAs that encode Ghrh and protein markers for neurochemicals that suppress (γ-aminobutyric acid) or enhance (nitric oxide; glutamate) counterregulation. SF-1 siRNA pretreatment respectively exacerbated or blunted hypoglycemia-associated inhibition of glutamate decarboxylase67 (GAD67/GAD1) and -65 (GAD65/GAD2) transcripts. Hypoglycemia augmented or reduced nitric oxide synthase and glutaminase mRNAs, responses that were attenuated by SF-1 gene silencing. Ghrh and Ghrh receptor transcripts were correspondingly refractory to or increased by hypoglycemia, yet SF-1 knockdown decreased both gene profiles. Hypoglycemic inhibition of ER-alpha and G protein-coupled-ER gene expression was amplified by SF-1 siRNA pretreatment, whereas as ER-beta mRNA was amplified. SF-1 knockdown decreased (corticosterone) or elevated [glucagon, growth hormone (GH)] basal counterregulatory hormone profiles, but amplified hypoglycemic hypercorticosteronemia and -glucagonemia or prevented elevated GH release. Outcomes document SF-1 control of VMN Ghrh neuron counterregulatory neurotransmitter and ER gene transcription. SF-1 likely regulates Ghrh nerve cell receptivity to estradiol and release of distinctive neurochemicals during glucose homeostasis and systemic imbalance. VMN Ghrh neurons emerge as a likely substrate for SF-1 control of glucose counterregulation in the male rat.

Targeted genome editing restores auditory function in adult mice with progressive hearing loss caused by a human microRNA mutation.

Mutations in microRNA-96 (MIR96) cause autosomal dominant deafness-50 (DFNA50), a form of delayed-onset hearing loss. Genome editing has shown efficacy in hearing recovery through intervention in neonatal mice, yet editing in the adult inner ear is necessary for clinical applications, which has not been done. Here, we developed a genome editing therapy for the MIR96 mutation 14C>A by screening different CRISPR systems and optimizing Cas9 expression and the sgRNA scaffold for efficient and specific mutation editing. AAV delivery of the KKH variant of Staphylococcus aureus Cas9 (SaCas9-KKH) and sgRNA to the cochleae of presymptomatic (3-week-old) and symptomatic (6-week-old) adult Mir9614C>A/+ mutant mice improved hearing long term, with efficacy increased by injection at a younger age. Adult inner ear delivery resulted in transient Cas9 expression without evidence of AAV genomic integration, indicating the good safety profile of our in vivo genome editing strategy. We developed a dual-AAV system, including an AAV-sgmiR96-master carrying sgRNAs against all known human MIR96 mutations. Because mouse and human MIR96 sequences share 100% homology, our approach and sgRNA selection for efficient and specific hair cell editing for long-term hearing recovery lay the foundation for the development of treatment for patients with DFNA50 caused by MIR96 mutations.

Antithrombotic Strategies According to Age: Insights from the AUGUSTUS Trial.

OBJECTIVE: We aimed to evaluate the safety and efficacy of antithrombotic strategies by age in patients with atrial fibrillation and acute coronary syndrome and/or percutaneous coronary intervention in AUGUSTUS. METHODS: Patients were stratified into 3 age groups: <65, 65-74, and ≥75 years. Outcomes of interest were major or clinically relevant non-major bleeding, major bleeding, death or rehospitalization, and ischemic events. Treatment effects of apixaban vs. vitamin K antagonist (VKA) and aspirin vs. placebo were assessed across age groups using Cox models. RESULTS: Of 4614 patients, 1267 (27.5%) were <65, 1802 (39.0%) were 65-74, and 1545 (33.5%) were ≥75 years. Apixaban was associated with lower rates of major or clinically relevant non-major bleeding than VKA (<65: HR 0.69 [0.47-1.00]; 65-74: HR 0.57 [0.43-0.75]; ≥75: HR 0.81 [0.63-1.04]). Death or hospitalization occurred less often with apixaban, regardless of age. No differences were observed in rates of ischemic events between apixaban and VKA according to age. Aspirin was associated with higher rates of bleeding than placebo (<65: HR 1.67 [1.15-2.43]; 65-74: HR 2.32 [1.73-3.10]; ≥75: HR 1.69 [1.31-2.19]). Rates of death or rehospitalization and ischemic events were similar among patients receiving aspirin or placebo across age groups. CONCLUSIONS: Apixaban was associated with greater absolute reduction in bleeding than VKA in older age groups, reflecting their higher hemorrhagic risk. Aspirin increased bleeding in all age groups vs. placebo. Our findings support the use of apixaban plus a purinergic receptor P2Y12(P2Y12) inhibitor without aspirin in patients with atrial fibrillation and recent acute coronary syndrome/percutaneous coronary intervention, regardless of age.

Mathematical Assessment of the Role of Intervention Programs for Malaria Control.

Malaria remains a global health problem despite the many attempts to control and eradicate it. There is an urgent need to understand the current transmission dynamics of malaria and to determine the interventions necessary to control malaria. In this paper, we seek to develop a fit-for-purpose mathematical model to assess the interventions needed to control malaria in an endemic setting. To achieve this, we formulate a malaria transmission model to analyse the spread of malaria in the presence of interventions. A sensitivity analysis of the model is performed to determine the relative impact of the model parameters on disease transmission. We explore how existing variations in the recruitment and management of intervention strategies affect malaria transmission. Results obtained from the study imply that the discontinuation of existing interventions has a significant effect on malaria prevalence. Thus, the maintenance of interventions is imperative for malaria elimination and eradication. In a scenario study aimed at assessing the impact of long-lasting insecticidal nets (LLINs), indoor residual spraying (IRS), and localized individual measures, our findings indicate that increased LLINs utilization and extended IRS coverage (with longer-lasting insecticides) cause a more pronounced reduction in symptomatic malaria prevalence compared to a reduced LLINs utilization and shorter IRS coverage. Additionally, our study demonstrates the impact of localized preventive measures in mitigating the spread of malaria when compared to the absence of interventions.

From multiplicity of infection to force of infection for sparsely sampled Plasmodium falciparum populations at high transmission.

High multiplicity of infection or MOI, the number of genetically distinct parasite strains co-infecting a single human host, characterizes infectious diseases including falciparum malaria at high transmission. It accompanies high asymptomatic Plasmodium falciparum prevalence despite high exposure, creating a large transmission reservoir challenging intervention. High MOI and asymptomatic prevalence are enabled by immune evasion of the parasite achieved via vast antigenic diversity. Force of infection or FOI, the number of new infections acquired by an individual host over a given time interval, is the dynamic sister quantity of MOI, and a key epidemiological parameter for monitoring the impact of antimalarial interventions and assessing vaccine or drug efficacy in clinical trials. FOI remains difficult, expensive, and labor-intensive to accurately measure, especially in high-transmission regions, whether directly via cohort studies or indirectly via the fitting of epidemiological models to repeated cross-sectional surveys. We propose here the application of queuing theory to obtain FOI on the basis of MOI, in the form of either a two-moment approximation method or Little's law. We illustrate these methods with MOI estimates obtained under sparse sampling schemes with the recently proposed " v a r coding" method, based on sequences of the v a r multigene family encoding for the major variant surface antigen of the blood stage of malaria infection. The methods are evaluated with simulation output from a stochastic agent-based model, and are applied to an interrupted time-series study from Bongo District in northern Ghana before and immediately after a three-round transient indoor residual spraying (IRS) intervention. We incorporate into the sampling of the simulation output, limitations representative of those encountered in the collection of field data, including under-sampling of v a r genes, missing data, and usage of antimalarial drug treatment. We address these limitations in MOI estimates with a Bayesian framework and an imputation bootstrap approach. We demonstrate that both proposed methods give good and consistent FOI estimates across various simulated scenarios. Their application to the field surveys shows a pronounced reduction in annual FOI during intervention, of more than 70%. The proposed approach should be applicable to the many geographical locations where cohort or cross-sectional studies with regular and frequent sampling are lacking but single-time-point surveys under sparse sampling schemes are available, and for MOI estimates obtained in different ways. They should also be relevant to other pathogens of humans, wildlife and livestock whose immune evasion strategies are based on large antigenic variation resulting in high multiplicity of infection.

Exploring online reproductive health promotion in Canada: a focus on behavioral and environmental influences from a sex and gender perspective.

BACKGROUND: Reproductive health promotion can enable early mitigation of behavioral and environmental risk factors associated with adverse pregnancy outcomes, while optimizing health of women + (all genders that can gestate a fetus) and babies. Although the biological and social influences of partners on pregnancy are well established, it is unknown whether online Canadian government reproductive health promotion also targets men and partners throughout the reproductive lifespan. METHODS: Reproductive health promotion, designed for the general public, was assessed in a multi-jurisdictional sample of Canadian government (federal, provincial/territorial, and municipal) and select non-governmental organization (NGO) websites. For each website, information related to environmental and behavioral influences on reproductive health (preconception, pregnancy, postpartum) was evaluated based on comprehensiveness, audience-specificity, and scientific quality. RESULTS: Government and NGO websites provided sparse reproductive health promotion for partners which was generally limited to preconception behavior topics with little coverage of environmental hazard topics. For women + , environmental and behavioral influences on reproductive health were well promoted for pregnancy, with content gaps for preconception and postpartum stages. CONCLUSION: Although it is well established that partners influence pregnancy outcomes and fetal/infant health, Canadian government website promotion of partner-specific environmental and behavioral risks was limited. Most websites across jurisdictions promoted behavioral influences on pregnancy, however gaps were apparent in the provision of health information related to environmental hazards. As all reproductive stages, including preconception and postpartum, may be susceptible to environmental and behavioral influences, online health promotion should use a sex- and gender-lens to address biological contributions to embryo, fetal and infant development, as well as contributions of partners to the physical and social environments of the home.

Comparison of Vegetarian Sausages: Proximal Composition, Instrumental Texture, Rapid Descriptive Sensory Method and Overall Consumer Liking.

The aim of the present research was to determine if the developed ovo-vegetarian sausage (SO), which was made with 15% chickpea flour, 51% albumin and 34% soy protein concentrate, exhibited improved physicochemical and sensory characteristics compared to vegetarian sausages available on the local market (classic vegan sausage, SC; vegan fine herb sausage, SH; and quinoa sausage, SQ). According to the physicochemical results, the developed sample, SO, presented significant differences (p < 0.05) compared to the others, including higher protein content, lower pH and a higher a* value. Three types of sensory analyses were conducted-flash profile, overall liking and purchase intention (to determine consumers' willingness to purchase the product)-with the first involving 15 consumers and the second and third involving 60 participants each. Descriptors for each sample were determined using the vocabulary provided by consumers in the flash profile analysis. Descriptors for SO included 'elastic', 'smell of cooked corn', 'characteristic flavor', 'pasty', 'soft' and 'pastel color', contributing to its greater overall liking and purchase intention compared to the others. Through the hierarchical multiple factor analysis, a positive correlation was observed between the texture and sensory descriptors of the flash profile. Conversely, a correlation was found between the physicochemical characteristics (pH, aw, color) and overall liking and purchase intention.

GLUT2 regulation of p38 MAPK isoform protein expression and p38 phosphorylation in male versus female rat hypothalamic primary astrocyte Cultures.

Recent studies documented regulation of hypothalamic astrocyte mitogen-activated protein kinase (MAPK) pathways, including p38, by the plasma membrane glucose carrier/sensor glucose transporter-2 (GLUT2). Sex-specific GLUT2 control of p38 phosphorylation was observed, but effects on individual p38 family protein profiles were not investigated. Current research employed an established primary astrocyte culture model, gene knockdown tools, and selective primary antisera against p38-alpha, p38-beta, p38-gamma, and p38-delta isoforms to investigate whether GLUT2 governs expression of one or more of these variants in a glucose-dependent manner. Data show that GLUT2 inhibits baseline expression of each p38 protein in male cultures, yet stimulates p38-delta profiles without affecting other p38 proteins in female. Glucose starvation caused selective up-regulation of p38-delta profiles in male versus p38-alpha and -gamma proteins in female; these positive responses were amplified by GLUT2 siRNA pretreatment. GLUT2 opposes or enhances basal p38 phosphorylation in male versus female, respectively. GLUT2 siRNA pretreatment did not affect glucoprivic patterns of phospho-p38 protein expression in either sex. Outcomes document co-expression of the four principal p38 MAPK family proteins in hypothalamic astrocytes, and implicate GLUT2 in regulation of all (male) versus one (female) variant(s). Glucoprivation up-regulated expression of distinctive p38 isoforms in each sex; these stimulatory responses are evidently blunted by GLUT2. Glucoprivic-associated loss of GLUT2 gene silencing effects on p38 phosphorylation infers either that glucose status determines whether this sensor controls phosphorylation, or that decrements in screened glucose in each instance are of sufficient magnitude to abolish GLUT2 regulation of that function.

Glucose transporter-2 regulation of VMN GABA neuron metabolic sensor and transmitter gene expression.

Glucose transporter-2 (GLUT2) monitors cellular glucose uptake. Astrocyte GLUT2 controls glucose counterregulatory hormone secretion. In vivo gene silencing and laser-catapult-microdissection tools were used here to investigate whether ventromedial hypothalamic nucleus (VMN) GLUT2 may regulate dorsomedial (VMNdm) and/or ventrolateral (VMNvl) γ-aminobutyric acid (GABA) neurotransmission to control this endocrine outflow in female rats. VMN GLUT2 gene knockdown suppressed or stimulated hypoglycemia-associated glutamate decarboxylase (GAD)1 and GAD2 mRNA expression in VMNdm versus VMNvl GABAergic neurons, respectively. GLUT2 siRNA pretreatment also modified co-expressed transmitter marker gene profiles in each cell population. VMNdm GABA neurons exhibited GLUT2 knockdown-sensitive up-regulated 5'-AMP-activated protein kinase-alpha1 (AMPKα1) and -alpha2 (AMPKα2) transcripts during hypoglycemia. Hypoglycemic augmentation of VMNvl GABA neuron AMPKα2 was refractory to GLUT2 siRNA. GLUT2 siRNA blunted (VMNdm) or exacerbated (VMNvl) hypoglycemic stimulation of GABAergic neuron steroidogenic factor-1 (SF-1) mRNA. Results infer that VMNdm and VMNvl GABA neurons may exhibit divergent, GLUT2-dependent GABA neurotransmission patterns in the hypoglycemic female rat. Data also document differential GLUT2 regulation of VMNdm versus VMNvl GABA nerve cell SF-1 gene expression. Evidence for intensification of hypoglycemic hypercorticosteronemia and -glucagonemia by GLUT2 siRNA infers that VMN GLUT2 function imposes an inhibitory tone on these hormone profiles in this sex.

2023 Cardiac Society of Australia and New Zealand Expert Position Statement on Catheter and Surgical Ablation for Atrial Fibrillation.

Catheter ablation for atrial fibrillation (AF) has increased exponentially in many developed countries, including Australia and New Zealand. This Expert Position Statement on Catheter and Surgical Ablation for Atrial Fibrillation from the Cardiac Society of Australia and New Zealand (CSANZ) recognises healthcare factors, expertise and expenditure relevant to the Australian and New Zealand healthcare environments including considerations of potential implications for First Nations Peoples. The statement is cognisant of international advice but tailored to local conditions and populations, and is intended to be used by electrophysiologists, cardiologists and general physicians across all disciplines caring for patients with AF. They are also intended to provide guidance to healthcare facilities seeking to establish or maintain catheter ablation for AF.

Clinical Course, Antifungal Susceptibility, and Genomic Sequencing of Trichophyton indotineae.

Importance: Trichophyton indotineae is an emerging dermatophyte causing outbreaks of extensive tinea infections often unresponsive to terbinafine. This species has been detected worldwide and in multiple US states, yet detailed US data on infections with T indotineae are sparse and could improve treatment practices and medical understanding of transmission. Objective: To correlate clinical features of T indotineae infections with in vitro antifungal susceptibility testing results, squalene epoxidase gene sequence variations, and isolate relatedness using whole-genome sequencing. Design, Setting, and Participants: This retrospective cohort study of patients with T indotineae infections in New York City spanned May 2022 to May 2023. Patients with confirmed T indotineae infections were recruited from 6 New York City medical centers. Main Outcome and Measure: Improvement or resolution at the last follow-up assessment. Results: Among 11 patients with T indotineae (6 male and 5 female patients; median [range] age, 39 [10-65] years), 2 were pregnant; 1 had lymphoma; and the remainder were immunocompetent. Nine patients reported previous travel to Bangladesh. All had widespread lesions with variable scale and inflammation, topical antifungal monotherapy failure, and diagnostic delays (range, 3-42 months). Terbinafine treatment failed in 7 patients at standard doses (250 mg daily) for prolonged duration; these patients also had isolates with amino acid substitutions at positions 393 (L393S) or 397 (F397L) in squalene epoxidase that correlated with elevated terbinafine minimum inhibitory concentrations of 0.5 µg/mL or higher. Patients who were treated with fluconazole and griseofulvin improved in 2 of 4 and 2 of 5 instances, respectively, without correlation between outcomes and antifungal minimum inhibitory concentrations. Furthermore, 5 of 7 patients treated with itraconazole cleared or had improvement at the last follow-up, and 2 of 7 were lost to follow-up or stopped treatment. Based on whole-genome sequencing analysis, US isolates formed a cluster distinct from Indian isolates. Conclusion and Relevance: The results of this case series suggest that disease severity, diagnostic delays, and lack of response to typically used doses and durations of antifungals for tinea were common in this primarily immunocompetent patient cohort with T indotineae, consistent with published data. Itraconazole was generally effective, and the acquisition of infection was likely in Bangladesh.

Immune features are associated with response to neoadjuvant chemo-immunotherapy for muscle-invasive bladder cancer.

Neoadjuvant cisplatin-based chemotherapy is standard of care for muscle-invasive bladder cancer (MIBC). Immune checkpoint inhibition (ICI) alone, and ICI in combination with chemotherapy, have demonstrated promising pathologic response (

Strategies adopted by informal carers to enhance participation in daily activities for persons with dementia.

OBJECTIVE: Carers for people with dementia commonly experience difficulty assisting the care-recipients with their daily activities and may adopt specific strategies to decrease the difficulties experienced. The objective of this qualitative study was to explore and understand the strategies used by carers to assist with daily activities for persons living with dementia. METHODS: Individual semi-structured interviews via face-to-face or telephone mode were conducted with 62 carers of persons living with dementia in Australia. Carers were asked about the strategies they have used previously, or are currently using, to assist with daily activity completion. Data were analysed via constant comparison and thematic analysis. RESULTS: All carers reported the need for strategies to accommodate the varying behaviour and functioning of the care-recipients. Participants reported a total of 207 strategies that fell into four main categories: (i) engage; (ii) adapt; (iii) orientate; and (iv) sense. The most used strategies were reported as those aimed at adapting the activity by using equipment to facilitate completion. CONCLUSIONS: Carers help persons living with dementia complete their daily activities by developing their own strategies based on the care-recipients' needs and personal preferences through a trial-and-error process. Carers can benefit if more advice is provided to them by health/social care professionals regarding what strategies may be helpful. Further studies are needed to develop these strategies into an educational package so that carers can be guided to use these strategies appropriately.

The Antiretroviral Pregnancy Registry: Three decades of prospective monitoring for birth defects.

PURPOSE: Antiretrovirals (ARVs) are life-saving drugs used for the treatment and prevention of HIV infection and antiviral drugs (AVs) for the treatment of chronic HBV infection. ARVs have proven highly effective in reducing perinatal HIV transmission, however the risk of birth defects from prenatal exposure to ARVs/AVs is an ongoing concern. The Antiretroviral Pregnancy Registry (APR), an international, prospective exposure-registration cohort study, monitors ARV and AV use in pregnancy for early signals of teratogenicity. This communication reports results of 30-years' experience of ARV/AV exposure during pregnancy and lessons learned through continuous quality improvement. METHODS AND RESULTS: Birth defect prevalence is estimated and compared to internal and external groups. Statistical inference is based on exact methods for binomial proportions. Between 2006 and 2023, cumulative enrollment more than tripled from 6893 to 25 960 pregnancies and ARVs/AVs monitored increased from 29 to 222. Through January 2023, there were 21 636 live births and 631 outcomes with birth defects, for overall prevalence of 2.9/100 live births (95% CI 2.7, 3.2). The birth defect prevalence was 3.0% (95% CI 2.7%, 3.3%) among first trimester exposures and 2.8% (95% CI 2.5%, 3.2%) among second/third trimester exposures (prevalence ratio 1.04 [95% CI 0.89, 1.21]). CONCLUSIONS: Birth defect prevalence is not statistically significantly different between first trimester ARV/AV pregnancy exposures compared to second/third trimester exposures and is also not different from two population-based surveillance systems: 2.72/100 live births reported in the Metropolitan Atlanta Congenital Defects Program (MACDP); and 4.17/100 live births from the Texas Birth Defects Registry (TBDR).

The impact of caregiving on the roles and valued activities of stroke carers: A systematic review of qualitative studies.

OBJECTIVE: To understand the experiences of informal carers and the impact of role and activity changes on their health and wellbeing. METHODS: A systematic search of CINHAL, MEDLINE, Embase, APA PsycInfo, and Web of Science was conducted. Studies were eligible if they included informal stroke carers (≥18 years), used a qualitative methodology, explored the roles and valued activities of stroke carers, and were published in English. The 10-item Critical Appraisal Skills Programme checklist for qualitative studies was used to assess methodological quality. The results of the included studies were thematically synthesised. RESULTS: A total of 36 qualitative studies were included and four overarching themes were identified: (1) Life adjustment; (2) Changing role and identity; (3) Changing activities: From meaningful to purposeful; and (4) Understanding and supporting carers. CONCLUSION: The sudden nature of stroke requires major readjustment in the carers life that has implications on their relationships, roles, and activities, subsequently impacting on their health and wellbeing. Health professionals and researchers should collaborate with stroke carers to identify their valued activities and implement realistic strategies to maintain these activities. Future interventions designed for carers should implement education about the importance of participating in valued activities and strategies to maintain these activities.
