A meta-analysis examining the impact of obesity on surgical site wound complications in patients undergoing primary ovarian cancer surgery.

The meta-analysis sought to evaluate and compare the effect of obesity on surgical site wound problems in subjects after primary ovarian cancer surgery. The results found by this meta-analysis were analyzed, and then odds ratio (OR) and mean difference (MD), at 95% confidence intervals (CIs), were calculated. These models might be dichotomous or contentious, random, or fixed effect models. The current meta-analysis included nine exams from 2009 to 2023, including 4362 females with primary ovarian cancer surgeries. Obesity had a significantly higher risk of surgical site wound infections (OR, 2.90; 95% CI, 2.27-3.69, p < 0.001), and wound problems (OR, 4.14; 95% CI, 1.83-9.34, p < 0.001) compared to non-obesity in females with primary ovarian cancer surgeries. It was revealed, by examining the data, that obesity was associated with significantly higher incidence of surgical site wound infections, and wound problems compared to non-obesity in females with primary ovarian cancer surgeries. However, attention should be given to the values because some of the comparisons included a small number of chosen studies,.

Comparative Efficacy of Inhaled and Intravenous Corticosteroids in Managing COVID-19-Related Acute Respiratory Distress Syndrome.

Acute respiratory distress syndrome (ARDS) is a life-threatening condition in which the lungs fail to provide sufficient oxygen to the body's vital organs. It is commonly associated with COVID-19 patients. Severe cases of COVID-19 can lead to lung damage and organ failure due to an immune response in the body. To mitigate these effects, corticosteroids, which are known for their anti-inflammatory properties, have been suggested as a potential treatment option. The primary focus of this study was to assess the impact of various corticosteroid administration methods on the outcomes of patients with COVID-19. Methods: The current study was conducted on COVID-19 patients divided into three groups. The first group was administered 6 mg of intravenous (IV) dexamethasone; the second group received 1 mg/kg of IV methylprednisolone (methylprednisolone); and the third group received budesonide respirable solution at a dosage of 1mg twice daily. The neubilizer used was a vibrating mesh nebulizer (VMN). All patients received standard care. We found that dexamethasone administered intravenously led to a significant reduction in C-reactive protein levels, surpassing the effectiveness of both IV methylprednisolone and inhaled budesonide. Oxygen saturation without mask change over time showed statistically significant differences (p = 0.004) in favor of the budesonide and dexamethasone groups for all days. Individuals who received methylprednisolone showed a significant decrease in mortality rate and an extended survival duration, with statistical significance observed at p = 0.024. The rest of the parameters, including ferritin, lymphocytes, total leukocyte count, platelets, hemoglobin, urea, serum potassium, serum sodium, serum creatinine, serum glutamic-pyruvic transaminase, serum glutamic-oxaloacetic transaminase, uric acid, albumin, globulin, erythrocyte sedimentation rate, international normalized ratio, oxygen saturation with flow, and oxygen flow, showed no statistically significant differences between the three drugs. In conclusion, treatment with IV methylprednisolone (1 mg/kg) resulted in a shorter hospital stay, decreased reliance on ventilation, and improved health outcomes for COVID-19 patients compared to using dexamethasone at a daily dosage of 6 mg or budesonide respirable solution at a dosage of 1mg twice daily.

Efficacy-based comparison between adults and children regarding using advanced counseling for asthma.

BACKGROUND: Asthma advanced counseling using smartphone applications has recently become one of the most effective and commonly used methods among adults and children with asthma. OBJECTIVES: We aimed to compare the advanced counseling effectiveness between adults and children with asthma. METHODS: A cohort prospective parallel study was performed on a group of adults and children nonsmoking patients with asthma, using a pressurized metered dose inhaler (pMDI). The patients were divided into two groups namely adults with asthma with ages ranging from 19 to 60 years and Children with asthma with ages ranging from 11 to 18 years, the two groups received a 2-month course of advanced counseling using "Asthma software" and "Asthma Dodge" smartphone applications, during which the two groups were monitored using the forced expiratory volume in the first second to the forced vital capacity (FEV1/FVC) ratio and asthma control test (ACT). The study has obtained ethical approval with the serial number REC-H-PhBSU-23002, adhering to the principles outlined in The Declaration of Helsinki, from the Ethical Approval Committee of Beni-Suef University Faculty of Pharmacy. RESULTS: With a total of 60 patients with asthma (N = 60), 31 adults (N = 31), and 29 children (N = 29), We found that starting from the first-month visit of counseling the children group showed superiority over the adult group in terms of the pulmonary function improvement p = .006. Also, regarding ACT scores the children group showed a superiority over the adult group this significance started from the first-month visit and continued to the second-month visit with p values = .032 and .011, respectively. CONCLUSION: The advanced counseling achieved better asthma control and pulmonary function improvement in children and adults; however, the improvement was much better in children with asthma than adults with asthma.

Light-mediated intracellular polymerization.

The synthesis of synthetic intracellular polymers offers groundbreaking possibilities in cellular biology and medical research, allowing for novel experiments in drug delivery, bioimaging and targeted cancer therapies. These macromolecules, composed of biocompatible monomers, are pivotal in manipulating cellular functions and pathways due to their bioavailability, cytocompatibility and distinct chemical properties. This protocol details two innovative methods for intracellular polymerization. The first one uses 2-hydroxy-4'-(2-hydroxyethoxy)-2-methylpropiophenone (Irgacure 2959) as a photoinitiator for free radical polymerization under UV light (365 nm, 5 mW/cm2). The second method employs photoinduced electron transfer-reversible addition-fragmentation chain-transfer polymerization with visible light (470 nm, 100 mW/cm2). We further elaborate on isolating these intracellular polymers by streptavidin/biotin interaction or immobilized metal ion affinity chromatography for polymers tagged with biotin or histidine. The entire process, from polymerization to isolation, takes ~48 h. Moreover, the intracellular polymers thus generated demonstrate significant potential in enhancing actin polymerization, in bioimaging applications and as a novel avenue in cancer treatment strategies. The protocol extends to animal models, providing a comprehensive approach from cellular to systemic applications. Users are advised to have a basic understanding of organic synthesis and cell biology techniques.

Amphiphilic Block Copolymers Containing Benzenesulfonyl Azide Groups as Visible Light-Responsive Drug Carriers for Image-Guided Delivery.

Nanoparticles (NPs) containing light-responsive polymers and imaging agents show great promise for controlled drug delivery. However, most light-responsive NPs rely on short-wavelength excitation, resulting in poor tissue penetration and potential cytotoxicity. Moreover, excessively sensitive NPs may prematurely release drugs during storage and circulation, diminishing their efficacy and causing off-target toxicity. Herein, we report visible-light-responsive NPs composed of an amphiphilic block copolymer containing responsive 4-acrylamide benzenesulfonyl azide (ABSA) and hydrophilic N,N'-dimethylacrylamide (DMA) units. The polymer pDMA-ABSA was loaded with the chemotherapy drug dasatinib and zinc tetraphenylporphyrin (ZnTPP). ZnTPP acted as an imaging reagent and a photosensitizer to reduce ABSA upon visible light irradiation, converting hydrophobic units to hydrophilic units and disrupting NPs to trigger drug release. These NPs enabled real-time fluorescence imaging in cells and exhibited synergistic chemophotodynamic therapy against multiple cancer cell lines. Our light-responsive NP platform holds great promise for controlled drug delivery and cancer theranostics, circumventing the limitations of traditional photosensitive nanosystems.

Application of different counseling strategies for better adult asthma control.

OBJECTIVE: We aimed to compare the effectiveness of three distinct counseling methods to determine the most effective approach. METHODS: In this prospective cohort study with a two-month follow-up, A group of non-smoking adults, aged 19-60 years, were randomly collected at outpatients clinic with prior asthma diagnosis, based on the forced expiratory volume in one seconds to forced vital capacity ratio (FEV1/FVC) and the guidelines outlined by the Global Initiative for Asthma (GINA), At the baseline assessment, all patients, underwent FEV1/FVC measurements, asthma symptom evaluations using Asthma Control Test (ACT), Asthma Control Questionnaire (ACQ), and GINA symptoms control assessment questionnaire, and assessment of pressurized metered-dose inhaler (pMDI) usage. The patients were divided into three groups, each assigned a distinct counseling strategy: traditional verbal counseling, advanced counseling utilizing the Asthma smartphone-application, and a combination of advanced-verbal counseling. We conducted a two-month monitoring period for all three groups. RESULTS: Significant differences (p < .001) were observed among the three counseling groups in ACT, FEV1/FVC ratio, and GINA symptoms control assessment scores from the first month to the second month visit. Regarding ACQ, the study unveiled a noteworthy disparity in ACQ scores during the second week, with a significant difference (p = .025) observed between the verbal and advanced-verbal counseling groups. Similarly, a significant difference (p = .016) was noted between the advanced counseling group and the advanced-verbal counseling groups. CONCLUSION: The study findings indicate that the combining advanced-verbal counseling by incorporating the Asthma smartphone-application alongside traditional verbal counseling is a more effective approach for improving asthma control in adults.

Perception of Burnout and Its Impact on Academic Hospitalists During COVID-19 and Institutional Strategies to Combat Burnout and Improve Wellness.

INTRODUCTION: Physician burnout has been alarmingly high, particularly among general internal medicine, which displays some of the highest rates. A recent study of academic hospitalists reported a higher level of burnout (62%) than the rates found in similar studies, but with agreement about factors leading to burnout, consequences of burnout, and importance of steps to prevent burnout. This study seeks to expand upon these results by investigating the impact of COVID-19 on burnout among hospitalists and uncovering the perspectives of frontline clinicians to formulate effective mitigation strategies. METHODS: Academic hospitalists were recruited to participate in a series of focus group interviews. The questions focused on contributors to burnout, the impact of COVID-19, and strategies to improve wellness and reduce burnout. The focus groups were audio-recorded, transcribed, and coded for emergent themes using Taguette, an open-source qualitative data analysis software. RESULTS: Burnout-inducing themes included workload, bureaucratic hurdles, and lack of control. COVID-19-specific themes included fear of exposing family and social isolation. The most common mitigation strategy was to increase social interactions to foster a sense of community. Additional solutions included adhering to a census cap of patients, streamlining clinical work, and providing avenues for two-way communication between leadership and clinicians to share concerns and elicit feedback. CONCLUSIONS: Streamlining clinical work allows more time for patient care. Enhancing community and fostering collaboration in decision-making allows clinicians to feel more empowered. A crucial first step to combat burnout is to encourage a work environment that values clinician well-being and proactively works to increase job satisfaction.
