Biological synthesis of silver nanoparticles using Senna auriculata flower extract for antibacterial activities.

In this study, biological synthesis of silver nanoparticles (AgNPs) using Senna auriculata flower extract for antibacterial activities was reported. The silver spectra compared to the plant extract show a rightward shift in AgNP peaks, indicating successful nanoparticle formation. The absorption band at 302 nm and the disappearance or shift of other peaks further confirm the synthesis. X-ray diffraction (XRD) analysis reveals that the AgNPs synthesized with S. auriculata extract have an average crystallite size of 25 nm. Transmission electron microscopy (TEM) results exhibited a polydispersed, spherical shape with sizes ranging from 70 nm, in clear contrast to the electron microscope image that showed their spherical shape. When examining the selected area electron diffraction (SAED) image, a specific set of lattice planes was correlated with a specific spot. A histogram of AgNP particle size distribution can be seen. AgNPs were tested against four different strains of bacteria for their antibacterial effectiveness, including gram negative bacteria (Escherichia coli, Klebsiella pneumoniae, and Staphylococcus aureus), as well as gram positive bacteria (S. aureus, d. Bacillus subtilis), at various concentrations of AgNP. The results of in vitro experiments indicate that AgNPs containing S. auriculata flowers inhibit amylase well. At two concentrations, ~16.03% and ~70.99%, AgNPs inhibit the reaction at low and high concentrations, respectively.

Effects of extrapulmonary TB on patient quality of life and recurrence.

BACKGROUND: Quantifying quality of life (QoL) in extrapulmonary TB patients is crucial yet often overlooked. This study examines the impact of tuberculous lymphadenitis and pleuritis on patients' QoL, associated factors, and recurrence. METHODS: Data were collected prospectively from patients using a pre-designed questionnaire at baseline, post-treatment, and 2 years after treatment. Health domains are essential to overall health and well-being and can be assessed to understand health status. We included mobility for physical well-being, usual activities for self-care, pain/discomfort for disease manifestations, and anxiety/depression for emotional health. RESULTS: Of the 376 patients, 53% had TB lymphadenitis, and 47% had TB pleuritis, with a mean age of 25 years (SD ±12.95). The most commonly reported issues at baseline were pain/discomfort and restricted usual activities. After treatment, over 90% experienced improvement, but 8% re-developed symptoms after 2 years, and two patients required retreatment for recurrent EPTB. Predictors negatively impacting QoL included private income sources, residence outside the city, and marriage, with the first two primarily affecting emotional health. CONCLUSION: Tuberculous lymphadenitis and pleuritis significantly impact patients' physical and emotional health, necessitating healthcare providers to address non-medical factors affecting QoL to reduce morbidity and mortality and improve QoL.

CONTEXTE: La quantification de la qualité de vie (QoL) chez les patients atteints de TB extrapulmonaire (EPTB) est essentielle mais fréquemment ignorée. Cette recherche analyse l'influence de la lymphadénite et de la pleurésie tuberculeuse sur la QoL des patients, les facteurs associés et la récurrence. MÉTHODES: Les données ont été collectées de manière prospective auprès des patients à l'aide d'un questionnaire préétabli, initialement, post-traitement et deux ans après le traitement. Les aspects de la santé sont fondamentaux pour le bien-être général et peuvent être évalués afin de comprendre l'état de santé. La mobilité a été incluse pour le bien-être physique, les activités quotidiennes pour les soins personnels, la douleur/l'inconfort pour les symptômes de la maladie et l'anxiété/la dépression pour la santé émotionnelle. RÉSULTATS: Sur les 376 patients, 53% ont été diagnostiqués avec une lymphadénite tuberculeuse et 47% avec une pleurite tuberculeuse, avec un âge moyen de 25 ans (SD ±12,95). Les symptômes les plus couramment signalés initialement étaient la douleur/l'inconfort et la limitation des activités habituelles. Après le traitement, plus de 90% des patients ont constaté une amélioration de leur état, mais 8% d'entre eux ont présenté à nouveau des symptômes après deux ans, et deux patients ont nécessité un nouveau traitement pour une EPTB récurrente. Les facteurs prédictifs qui ont un effet négatif sur la QoL incluaient les sources de revenus privées, la résidence en dehors de la ville et le mariage, les deux premiers ayant principalement un impact sur la santé émotionnelle. CONCLUSION: La lymphadénite tuberculeuse et la pleurite ont un impact important sur la santé physique et émotionnelle des patients, ce qui nécessite que les professionnels de la santé abordent les facteurs non médicaux qui affectent la QoL afin de diminuer la morbidité et la mortalité, et d'améliorer la QoL.

International treatment outcomes of neonates on extracorporeal membrane oxygenation (ECMO) with persistent pulmonary hypertension of the newborn (PPHN): a systematic review.

BACKGROUND: PPHN is a common cause of neonatal respiratory failure and is still a serious condition and associated with high mortality. OBJECTIVES: To compare the demographic variables, clinical characteristics, and treatment outcomes in neonates with PHHN who underwent ECMO and survived compared to neonates with PHHN who underwent ECMO and died. METHODS: We adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline and searched ProQuest, Medline, Embase, PubMed, CINAHL, Wiley online library, Scopus and Nature for studies on the development of PPHN in neonates who underwent ECMO, published from January 1, 2010 to May 31, 2023, with English language restriction. RESULTS: Of the 5689 papers that were identified, 134 articles were included in the systematic review. Studies involving 1814 neonates with PPHN who were placed on ECMO were analyzed (1218 survived and 594 died). Neonates in the PPHN group who died had lower proportion of normal spontaneous vaginal delivery (6.4% vs 1.8%; p value > 0.05) and lower Apgar scores at 1 min and 5 min [i.e., low Apgar score: 1.5% vs 0.5%, moderately abnormal Apgar score: 10.3% vs 1.2% and reassuring Apgar score: 4% vs 2.3%; p value = 0.039] compared to those who survived. Neonates who had PPHN and died had higher proportion of medical comorbidities such as omphalocele (0.7% vs 4.7%), systemic hypotension (1% vs 2.5%), infection with Herpes simplex virus (0.4% vs 2.2%) or Bordetella pertussis (0.7% vs 2%); p = 0.042. Neonates with PPHN in the death group were more likely to present due to congenital diaphragmatic hernia (25.5% vs 47.3%), neonatal respiratory distress syndrome (4.2% vs 13.5%), meconium aspiration syndrome (8% vs 12.1%), pneumonia (1.6% vs 8.4%), sepsis (1.5% vs 8.2%) and alveolar capillary dysplasia with misalignment of pulmonary veins (0.1% vs 4.4%); p = 0.019. Neonates with PPHN who died needed a longer median time of mechanical ventilation (15 days, IQR 10 to 27 vs. 10 days, IQR 7 to 28; p = 0.024) and ECMO use (9.2 days, IQR 3.9 to 13.5 vs. 6 days, IQR 3 to 12.5; p = 0.033), and a shorter median duration of hospital stay (23 days, IQR 12.5 to 46 vs. 58.5 days, IQR 28.2 to 60.7; p = 0.000) compared to the neonates with PPHN who survived. ECMO-related complications such as chylothorax (1% vs 2.7%), intracranial bleeding (1.2% vs 1.7%) and catheter-related infections (0% vs 0.3%) were more frequent in the group of neonates with PPHN who died (p = 0.031). CONCLUSION: ECMO in the neonates with PPHN who failed supportive cardiorespiratory care and conventional therapies has been successfully utilized with a neonatal survival rate of 67.1%. Mortality in neonates with PPHN who underwent ECMO was highest in cases born via the caesarean delivery mode or neonates who had lower Apgar scores at birth. Fatality rate in neonates with PPHN who underwent ECMO was the highest in patients with higher rate of specific medical comorbidities (omphalocele, systemic hypotension and infection with Herpes simplex virus or Bordetella pertussis) or cases who had PPHN due to higher rate of specific etiologies (congenital diaphragmatic hernia, neonatal respiratory distress syndrome and meconium aspiration syndrome). Neonates with PPHN who died may need a longer time of mechanical ventilation and ECMO use and a shorter duration of hospital stay; and may experience higher frequency of ECMO-related complications (chylothorax, intracranial bleeding and catheter-related infections) in comparison with the neonates with PPHN who survived.

Pure Hereditary Spastic Paraplegia in a Patient With a Novel Heterozygous KIDINS220 Gene Mutation.

This case presents a somewhat unique and different phenotype of hereditary spastic paraplegia from previously reported kinase D-interacting substrate of 220 kDa (KIDINS220) gene mutation-related disease. We report a unique putative causative heterozygous mutation in KIDINS220 in a pure hereditary spastic paraplegia (HSP) patient expanding the HSP group further. We also deliberate on how our case was different from prior KIDINS220-related pathologies including spastic paraplegia, intellectual disability, nystagmus, and obesity (SINO) syndrome, and the observation of KIDINS220 and aquaporin-4 (AQP4) downregulation in the ventricular ependymal lining of idiopathic normal pressure hydrocephalus (iNPH) patients. These findings warrant further investigations of the biology of KIDINS220. With the advent of new gene editing technologies like Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/CRISPR-associated protein 9 (Cas9), variants such as ours provide an opportunity for targeted precision medicine.

Genetic variants affect diurnal glucose levels throughout the day.

Circadian rhythms not only coordinate the timing of wake and sleep but also regulate homeostasis within the body, including glucose metabolism. However, the genetic variants that contribute to temporal control of glucose levels have not been previously examined. Using data from 420,000 individuals from the UK Biobank and replicating our findings in 100,000 individuals from the Estonian Biobank, we show that diurnal serum glucose is under genetic control. We discover a robust temporal association of glucose levels at the Melatonin receptor 1B (MTNR1B) (rs10830963, P = 1e-22) and a canonical circadian pacemaker gene Cryptochrome 2 (CRY2) loci (rs12419690, P = 1e-16). Furthermore, we show that sleep modulates serum glucose levels and the genetic variants have a separate mechanism of diurnal control. Finally, we show that these variants independently modulate risk of type 2 diabetes. Our findings, together with earlier genetic and epidemiological evidence, show a clear connection between sleep and metabolism and highlight variation at MTNR1B and CRY2 as temporal regulators for glucose levels.

Prevalence and determinants of low back pain among residents in Abha City, Saudi Arabia.

Background: Healthcare work is a major risk for having musculoskeletal disorders (MSDs), including low back pain (LBP). This study aimed to estimate the prevalence of LBP and define its associated risk factors among resident physicians. Material and Methods: A descriptive cross-sectional survey was conducted among all resident physicians of all specialties in Abha city during the period from July 2020 to September 2020. Data were collected using an online pre-structured data collection tool. The Nordic Musculoskeletal Questionnaire (NMQ) (back pain section) was applied to assess the effect of LBP on the residents' ability to perform job duties effectively. Results: A total of 312 resident physicians responded. Their age ranged between 25 and 41 years. Males represented 57.7% of them. The prevalence of LBP was 64.7%. The most common reported aggravating factors for LBP were working in uncomfortable posture (73.3%), standing for long periods (64.4%), and long sitting sessions (51.5%). Regarding the pain-relieving factors, sleeping ranked first (60.4%), followed by taking analgesics (48.5%) and maintaining a good posture (35.6%). Multivariate logistic regression analysis revealed that obese subjects were at higher risk than underweight subjects to develop LBP (adjusted odds ratio (AOR) =6.18, 95% confidence interval (CI): 1.26-30.34, P = 0.025). Compared to resident physicians without family history of back pain, those with such history were at almost 4-fold higher risk of developing LBP (AOR = 3.90, 95% CI: 2.33-6.52, P < 0.001). Conclusion: LBP is a very prevalent problem among resident physicians, particularly obese subjects and those with family history of back pain. LBP adversely impacts the work performance of the affected physicians.

The role of accelerometer-derived sleep traits on glycated haemoglobin and glucose levels: a Mendelian randomization study.

Self-reported shorter/longer sleep duration, insomnia, and evening preference are associated with hyperglycaemia in observational analyses, with similar observations in small studies using accelerometer-derived sleep traits. Mendelian randomization (MR) studies support an effect of self-reported insomnia, but not others, on glycated haemoglobin (HbA1c). To explore potential effects, we used MR methods to assess effects of accelerometer-derived sleep traits (duration, mid-point least active 5-h, mid-point most active 10-h, sleep fragmentation, and efficiency) on HbA1c/glucose in European adults from the UK Biobank (UKB) (n = 73,797) and the MAGIC consortium (n = 146,806). Cross-trait linkage disequilibrium score regression was applied to determine genetic correlations across accelerometer-derived, self-reported sleep traits, and HbA1c/glucose. We found no causal effect of any accelerometer-derived sleep trait on HbA1c or glucose. Similar MR results for self-reported sleep traits in the UKB sub-sample with accelerometer-derived measures suggested our results were not explained by selection bias. Phenotypic and genetic correlation analyses suggested complex relationships between self-reported and accelerometer-derived traits indicating that they may reflect different types of exposure. These findings suggested accelerometer-derived sleep traits do not affect HbA1c. Accelerometer-derived measures of sleep duration and quality might not simply be 'objective' measures of self-reported sleep duration and insomnia, but rather captured different sleep characteristics.

Sleep and home parenteral nutrition in adults: A narrative review.

Infusions of home parenteral nutrition (HPN) are often cycled at night coinciding with sleep episodes. Adult consumers of HPN are known to experience poor sleep attributed to frequent awakenings and long durations of wakefulness after falling asleep. Consequently, most consumers do not meet recommendations for sleep duration and quality or daytime napping. The primary underlying pathophysiology resulting in sleep problems is nocturia; however, other factors also exist, including disruptions caused by medical equipment (ie, pump alarms), comorbid conditions, dysglycemia, and medication use. Early guidance on sleep is imperative because of the central role of sleep in physical health and wellbeing, including mitigating complications, such as infection risk, gastrointestinal problems, pain sensitivity, and fatigue. Clinicians should routinely inquire about the sleep of their patients and address factors known to perturb sleep. Nonpharmacologic opportunities to mitigate sleep problems include education on healthy sleep practices (ie, sleep hygiene); changes in infusion schedules, volumes, rates, and equipment; and, possibly, behavioral interventions, which have yet to be examined in this population. Addressing comorbid conditions, such as mood disorders, and nutrition deficiencies may also help. Pharmacologic interventions and technological advancement in HPN delivery are also needed. Research on sleep in this population is considered a priority, yet it remains limited at this time.

Retracted Publications in Otolaryngology-Head and Neck Surgery: What Mistakes Are Being Made?

Objectives: Retraction of publications is critical to maintaining scientific integrity, yet there is a lack of research on its occurrence in Otolaryngology. This study investigates characteristics, trends, and reasons for retraction of publications in otolaryngology journals. Study Design: Bibliometric analysis. Setting: PubMed, Scopus, Web of Science. Methods: A PubMed search for publications retracted during 1990 to 2022 from the top 60 journals with the subject "Otorhinolaryngology" using Scopus' CiteScore was performed. Publications were excluded if they were not in English, had missing information or did not have available abstracts or full-text. Publication and retraction dates, journal, country of origin, citation counts, journal impact factor (JIF), topic, and reason for retraction were recorded. Pearson correlation coefficients were calculated to identify potential associations in the data. Results: Fifty-three publications were included. The 2020s had the highest number of retractions per year (4.33), with publications being retracted on average, 35 months after initial publication. The most common retracted topic and country of origin were head and neck (26.4%) and China (17.0%), respectively. Most publications were retracted because of plagiarism or duplicate publication (52.8%). Mean citation count was 6.92 ± 8.32 and mean JIF was 2.80 ± 1.35. Citation count was positively associated with months until retraction (r = .432, P = .001). There was no significant correlation between months to retraction and JIF (r = .022, P = .878). Conclusion: The most cited reasons for retraction were plagiarism and duplicate publication. An understanding of the reasons for retraction can better position journals to enforce more meticulous review standards and reduce such publications from being published. Level of Evidence: Level 4.

Plasma metabolomics changes comparing daytime to overnight infusions of home parenteral nutrition in adult patients with short bowel syndrome: Secondary analysis of a clinical trial.

BACKGROUND: Home parenteral nutrition (HPN) is often cycled nocturnally and is expected to result in glucose intolerance and sleep disruption partly due to circadian misalignment. This study aimed to define the metabolic response when HPN is cycled during the daytime compared to overnight. METHODS: This secondary analysis leveraged samples from a clinical trial in adults with short bowel syndrome consuming HPN (ClinicalTrials.gov: NCT04743960). Enrolled patients received 1 week of HPN overnight followed by 1 week of HPN during the daytime. Fasting blood samples were collected following each study period and global metabolic profiles were examined from plasma samples. Differential metabolite abundance was determined from normalized and scaled data using adjusted Linear Models for MicroArray Data models followed by pathway enrichment analysis. RESULTS: Nine patients (mean age, 52.6 years; 78% female; mean BMI 20.7 kg/m2) provided samples. Among 622 identified metabolites, changes were observed in 36 metabolites at Punadj < 0.05 with higher abundance of fatty acids, long-chain and polyunsaturated fatty acids (Dihomo-gamma-linolenic acid, arachidonate (20:4n6), docosahexaenoate (DHA; 22:6n3)) and glycerolipids with daytime infusions. Enrichment analysis identified changes in pathways related to the biosynthesis of unsaturated fatty acids, d-arginine, and d-ornithine metabolism, and linoleic acid metabolism (Punadj<0.05). CONCLUSION: Daytime infusions of HPN may result in changes in circulating lipids and amino acid composing metabolic pathways previously implicated in circadian rhythms. As this is the first untargeted metabolomics study of HPN, larger studies are needed.

Screening and Treatment of Posttraumatic Stress Disorder in Wildfire Evacuees: A Cost-Utility Analysis.

Background. Global climate change is resulting in dramatic increases in wildfires. Individuals exposed to wildfires experience a high burden of posttraumatic stress disorder (PTSD), and the cost-effectiveness of the treatment options to address PTSD from wildfires has not been studied. The objective of this study was to conduct a cost-utility analysis comparing screening followed by treatment with paroxetine or trauma-focused cognitive behavioral therapy (TF-CBT) versus no screening in Canadian adult wildfire evacuees. Methods. Using a Markov model, quality-adjusted life-years (QALYs) and costs were evaluated over a 5-y time horizon using health care and societal perspectives. All costs and utilities in the model were discounted at 1.5%. Probabilistic and deterministic sensitivity analyses examined the uncertainty in the incremental net monetary benefit (INMB) under a willingness-to-pay threshold of $50,000. Results. From a societal perspective, no screening (NMB = $177,641) was dominated by screening followed by treatment with paroxetine (NMB = $180,733) and TF-CBT (NMB = $181,787), with TF-CBT having the highest likelihood of being cost-effective at a willingness-to-pay threshold of $50,000 per QALY (probability = 0.649). The initial prevalence of PTSD, probability of acceptance of treatment, and costs of productivity had the largest impact on the INMB of both paroxetine or TF-CBT versus no screening. Neither intervention was cost-effective at a willingness-to-pay threshold of $50,000 per QALY from a health care perspective. Interpretation. Screening followed by treatment with paroxetine or TF-CBT compared with no screening was found to be cost-saving while providing additional QALYs in wildfire evacuees. Governments should consider funding screening programs for PTSD followed by treatment with TF-CBT for wildfire evacuees. Highlights: Two prior studies examined the cost-effectiveness of screening followed by treatment for PTSD among individuals exposed to other disaster-type events (i.e., terrorist attack and Hurricane Sandy) and found screening followed by treatment (i.e., cognitive behavioral therapy [CBT]) to be highly cost-effective.Among wildfire evacuees, screening followed by treatment with paroxetine or trauma-focused (TF)-CBT provides additional quality-adjusted life-years (QALYs) and is cost-saving from a societal perspective. TF-CBT was the treatment option found most likely to be cost-effective.Neither treatment option was cost-effective at a willingness-to-pay threshold of $50,000 per QALY from a health care perspective.Screening programs for PTSD should be considered for wildfire evacuees, and individuals diagnosed with PTSD could be prescribed either TF-CBT or paroxetine depending on their preference and resources availability.

Using routinely collected clinical data for circadian medicine: A review of opportunities and challenges.

A wealth of data is available from electronic health records (EHR) that are collected as part of routine clinical care in hospitals worldwide. These rich, longitudinal data offer an attractive object of study for the field of circadian medicine, which aims to translate knowledge of circadian rhythms to improve patient health. This narrative review aims to discuss opportunities for EHR in studies of circadian medicine, highlight the methodological challenges, and provide recommendations for using these data to advance the field. In the existing literature, we find that data collected in real-world clinical settings have the potential to shed light on key questions in circadian medicine, including how 24-hour rhythms in clinical features are associated with-or even predictive of-health outcomes, whether the effect of medication or other clinical activities depend on time of day, and how circadian rhythms in physiology may influence clinical reference ranges or sampling protocols. However, optimal use of EHR to advance circadian medicine requires careful consideration of the limitations and sources of bias that are inherent to these data sources. In particular, time of day influences almost every interaction between a patient and the healthcare system, creating operational 24-hour patterns in the data that have little or nothing to do with biology. Addressing these challenges could help to expand the evidence base for the use of EHR in the field of circadian medicine.

Diagnostic Accuracy of Integrating Ultrasound and Shear Wave Elastography in Assessing Carpal Tunnel Syndrome Severity: a Prospective Observational Study.

Purpose: Carpal tunnel syndrome (CTS) is a common condition characterized by compression of the median nerve (MN) within the carpal tunnel. Accurate diagnosis and assessment of CTS severity are crucial for appropriate management decisions. This study aimed to investigate the combined diagnostic utility of B-mode ultrasound (US) and shear wave elastography (SWE) for assessing the severity of CTS in comparison to electrodiagnostic tests (EDT). Materials and Methods: This prospective observational study was conducted over 9-month periods at a tertiary care hospital. A total of 48 patients (36 females, 12 males; mean age 44 ± 10.9 years; age range 28-57 years) with clinically suspected CTS were enrolled. All patients underwent EDT, US, and SWE. Based on the EDT results, CTS cases were categorized into four groups: mild, moderate, severe, and negative. The cross-sectional area (CSA) and elasticity (E) of the MN were measured at the tunnel inlet (CSAu and Eu) and pronator quadratus region (CSAo and Eo). The differences (CSAu-CSAo and Eu-Eo) were calculated. The primary outcomes were the diagnostic performance of CSAu, CSAu-CSAo, Eu, and Eu-Eo in differentiating moderate/severe from mild/negative CTS compared to EDT findings. Secondary outcomes included a correlation of US/SWE parameters with EDT grades and between each other. ANOVA, correlation, regression, and receiver operating characteristic (ROC) curve analyses were performed. Results: CSAu and CSAu-CSAo increased progressively with worsening CTS severity. E measurements were significantly higher in moderate-to-severe CTS compared to mild or negative cases. The combined metric of CSAu-CSAo at a 5 mm threshold exhibited enhanced performance, with a higher sensitivity (83.3%), specificity (100%), and area under the curve (AUC) (0.98), surpassing the results of CSAu when used independently. Similarly, the SWE measurements indicated that Eu-Eo at a 56.1kPa cutoff achieved an AUC of 0.95, with a sensitivity of 93.3% and specificity of 94.4%, outperforming the metrics for Eu when used alone, which had an AUC of 0.93, with identical sensitivity and specificity values (93.3% and 94.4%, respectively). Conclusion: The integration of ultrasound, shear wave elastography, and electrodiagnostic tests provides a comprehensive approach to evaluate anatomical and neurological changes and guide management decisions for CTS.

Corridor and real-time 6-minute walk tests in healthy young adults: A randomized cross-over study.

Objective: Cardiopulmonary endurance is important for comfortably participating in activities of daily living. Exercise tests, such as the 6-minute walk test (6MWT), are commonly used to evaluate cardiopulmonary endurance. We investigated the effects of the Gait Real-Time Analysis Interactive Lab (GRAIL)- and corridor-based 6MWTs on functional performance. Methods: Thirty healthy men were randomly divided into two groups. Group A participants performed a corridor-based 6MWT, followed by a washout period (1 h). Subsequently, they performed the GRAIL-based 6MWT. Group B participants performed the tests in the reverse order of that performed by Group A participants. Results: The corridor-based 6MWT resulted in significantly higher 6MW distance and 6MW speed than the GRAIL-based 6MWT. No significant differences were observed between the two groups in any of the following secondary outcomes: systolic blood pressure, diastolic blood pressure, oxygen saturation, heart rate, dyspnea, and overall fatigue. A strong positive correlation was observed between the 6MW distance and 6MW speed. Conclusion: The corridor- and GRAIL-based 6MWT should not be used interchangeably.

Healthy Sleep Practices for Consumers of Home Total Parenteral Nutrition: A Mixed-Methods Community-Based Participatory Study.

Background: Consumers of overnight home parenteral nutrition (HPN) often experience sleep disruption; however, existing healthy sleep recommendations are widely inapplicable to consumers. Objectives: The aim of this mixed-methods, community-based participatory research study was to develop tailored recommendations on healthy sleep practices for HPN consumers. Methods: The multipart study involved the following: 1) an initial draft of sleep recommendations based on the evaluation of existing general sleep hygiene guidelines by an expert panel of clinicians and consumers with lived experience; 2) semi-structured focus groups with consumers and clinicians; 3) pre- and post-knowledge tests completed by consumers, and 4) final approval of the recommendations by the expert panel. Results: The literature synthesis resulted in 51 recommendations evaluated for relevance for HPN consumers. Focus groups with 20 HPN consumers and clinicians contributed additional recommendations based on lived experience. Ultimately, the final resource included recommendations spanning 4 sections: getting ready for bed, preparing the bedroom for sleep, daytime behaviors, and overall strategies for better sleep. Of the 36 recommendations, 58% were derived from existing general sleep hygiene guidelines, and the remaining 42% addressed sleep challenges experienced uniquely by consumers, including nocturnal polyuria, noise/light from medical equipment, and infusion schedules. Knowledge tests completed by 10 additional consumers indicated a modest increase in sleep health knowledge. Conclusions: The curated healthy sleep resource tailored for HPN consumers was facilitated by a multidisciplinary expert panel, a strategic collaboration with members of the HPN community and their clinicians, and in partnership with patient advocacy and support organizations. The wide distribution of these resources may improve the overall well-being of HPN consumers.

Penile erection and cardiovascular function: effects and pathophysiology.

Penile erection (PE) is a hemodynamic event that results from a neuroendocrine process, and it is influenced by the cardiovascular status of the patient. However, it may also modulate an individual's cardiovascular events. The present study provides the mechanisms involved in the association of PE and cardiovascular function. Erection upsurges the cardiac rate, blood pressure, and oxygen uptake. Sex-enhancing strategies, such as phosphodiesterase inhibitors, alprostadil, and testosterone also promote vasodilatation and cardiac performance, thus preventing myocardial infarction. More so, drugs that are used in the treatment of hypertensive heart diseases (such as angiotensin system inhibitors and ß-blockers) facilitate vasodilatation and PE. These associations have been linked with nitric oxide- and testosterone-dependent enhancing effects on the vascular endothelium. In addition, impaired cardiovascular function may negatively impact PE; therefore, impaired PE may be a pointer to cardiovascular pathology. Hence, evaluation of the cardiovascular status of an individual with erectile dysfunction (ED) is essential. Also, employing strategies that are used in maintaining optimal cardiac function may be useful in the management of ED.

Home parenteral nutrition, sleep patterns, and depressive symptoms: Secondary analysis of cross-sectional data.

BACKGROUND: Patients receiving home parenteral nutrition (HPN) are known to experience psychological distress and have profoundly disrupted sleep. The aim of this analysis was to examine the relationship between sleep patterns with depressive symptoms and HPN characteristics. METHODS: The study was a secondary analysis of cross-sectional data examining sleep patterns using subjective and objective measures. Sleep was assessed by surveys and 7-day actigraphy. The Patient Health Questionnaire-8 was used to evaluate depressive symptoms. Participants provided information on HPN. Spearman correlations were calculated between sleep measures with depressive symptoms and HPN characteristics. Correlations were further examined in multivariable linear regression models. RESULTS: Thirty-two adults (age = 53 years; 75% female; 94% White) were included. Lower sleep quality (r = 0.54-0.60; P < 0.001) and later sleep timing (r = -0.35; P = 0.049) were correlated with higher depressive symptoms. Sleep patterns were also correlated with several HPN characteristics (r = -0.47 to 0.51). In linear regression models, rate of infusion was associated with sleep duration (ß = -0.004 [0.002] h; P = 0.046) in which each 100 mL/h was associated with 24-min shorter duration. Higher total energy was associated with lower sleep quality (ß = 0.0004 [0.0002] log-unit; P = 0.042), and higher volume was associated with longer sleep onset latency (ß = 0.0006 [0.0003] log-min; P = 0.049). CONCLUSIONS: We provide evidence supporting the link between poor and later sleep with higher depressive symptoms and identify potentially modifiable infusion characteristics (notably, slower rate of infusion and lower total energy and volume) that, on further verification, may support sleep among those receiving HPN.

Underdiagnosis of Borderline oxacillin-resistant Staphylococcus aureus (BORSA) - Case series.

Borderline oxacillin-resistant Staphylococcus aureus (BORSA) are mecA-negative strains with oxacillin minimum inhibitor concentration (MIC) close to the resistance breakpoint of ≥ 4µg/mL. Instead of producing penicillin-binding protein with low affinity to methicillin (oxacillin) mediated by mecA gene as in methicillin-resistant S. aureus (MRSA), BORSA strains are characterised by the hyperproduction of ß-lactamase enzymes, thus able to break down methicillin. Common laboratory methods to detect MRSA such as cefoxitin disk diffusion alone may fail to detect methicillin resistance due to BORSA. We report five cases of BORSA blood-stream infections in a university teaching hospital. All isolates were found to be susceptible to cefoxitin using disk diffusion, resistant to oxacillin using automated MIC method, and did not harbour mecA gene. All patients were suscessfully treated with anti-MRSA antibiotics, and removal of primary sources were done if identified. A more cost-effective method for screening and diagnosis of BORSA is needed in addition to cefoxitin disk diffusion test, in order to monitor the spread, and to enable routine detection and treatment of this pathogen.

The Saudi initiative for asthma - 2024 update: Guidelines for the diagnosis and management of asthma in adults and children.

The Saudi Initiative for Asthma 2024 (SINA-2024) is the sixth version of asthma guidelines for the diagnosis and management of asthma for adults and children that was developed by the SINA group, a subsidiary of the Saudi Thoracic Society. The main objective of the SINA is to have guidelines that are up-to-date, simple to understand, and easy to use by healthcare workers dealing with asthma patients. To facilitate achieving the goals of asthma management, the SINA Panel approach is mainly based on the assessment of symptom control and risk for both adults and children. The approach to asthma management is aligned for age groups: adults, adolescents, children aged 5-12 years, and children aged <5 years. SINA guidelines have focused more on personalized approaches reflecting a better understanding of disease heterogeneity with the integration of recommendations related to biologic agents, evidence-based updates on treatment, and the role of immunotherapy in management. The medication appendix has also been updated with the addition of recent evidence, new indications for existing medication, and new medications. The guidelines are constructed based on the available evidence, local literature, and the current situation at national and regional levels. There is also an emphasis on patient-doctor partnership in the management that also includes a self-management plan.
