Factors Influencing Parental Willingness to Consent to a Survey Study for Patients in the Pediatric Emergency Department.

OBJECTIVE: To identify factors that impact parental willingness to consent to research studies conducted for their children during visits to pediatric emergency departments (EDs). METHODS: Parents and guardians of children receiving care in our pediatric ED were approached and asked if they would be willing to let their child participate in a research study requiring the child to complete an electronic questionnaire. No such questionnaire existed, however, because the primary purpose was to ascertain the parent's willingness to let their child participate. All parents were debriefed and informed of the true purpose of the study and asked to complete a survey themselves to help understand factors that influenced their initial decision of whether to consent. Bivariate tests and logistic regression were used to evaluate unadjusted and adjusted associations between parent and patient characteristics and parental consent decision. RESULTS: We approached 431 eligible parents about the hypothetical research study involving their children, and 386 (89.6%) consented for their children to participate. After the debriefing, 392 (91.0%) parents consented to complete the parental survey. We observed statistically significant associations between shorter length of ED stay to approach for consent for the study ( P = 0.048) as well as longer travel time ( P = 0.03) and willingness to consent in bivariate analysis, though this did not hold in regression analysis. Regression analysis revealed parents of children who have previously participated in research had 79 times lower odds of consenting to participate in our study adjusted for parent race, ethnicity, actual and perceived length of stay, travel time to the ED, and altruism. CONCLUSIONS: A high proportion of parents consented to their child participating in research in our ED with previous child participation in research being associated with lower odds of parental consent even when adjusted for other factors. Our findings may inform future research practices and studies investigating parental perceptions and motivations surrounding research studies.

Entrepreneurial leadership, nurses' proactive work behavior, and career adaptability: a structural equation model.

BACKGROUND: Healthcare organizations with practitioners who exhibit proactive work behavior and career adaptability acquire a competitive advantage in the face of many adversities. Entrepreneurial leadership (EL) is a new leadership approach that has a huge impact on followers' behavior, although research into its theory and empirical evidence is still in its infancy. METHODS: A non-probability convenience sample methodology (n = 450) was utilized to choose study participants, who were equally dispersed among the two private hospitals in Alexandria. A cross-sectional study was carried out in all departments of the hospitals, which were chosen at random using a simple random procedure. Three validated scales were used in this study to measure the study variables and establish a structural equation model. RESULTS: The result of this study revealed that nurses perceived moderate mean scores of all variables; entrepreneurial leadership (140.84 ± 11.94), proactive work behavior (46.02 ± 5.85), and career adaptability (85.55 ± 10.35). In addition, the structured equation model revealed a goodness fit index and presents that entrepreneurial leadership significantly affects nurses' proactive work behavior with an estimated ß of 0.555, coefficient of regression C.R. of 4.006, at P value < 0.001. Also, it significantly affects career adaptability with an estimated ß of .834, a coefficient of regression C.R. of 3.491 at P value < 0.001. CONCLUSIONS: The developed structural equation model confirmed the significant impact of entrepreneurial leadership (EL) on nurses' proactive work behavior (PWB) and career adaptability (CA)". Therefore, this study offers important implications for nurse managers, staff nurses, hospital human resources management practice, and academics.

Prior trauma experiences among state patients charged with murder: A retrospective records review.

Background: Trauma experiences, particularly in childhood, have been associated with criminality and mental illness. There is a paucity of research into the crime of murder, trauma and mental illness. Aim: This research study focused on state patients charged with murder and sought to determine associations with prior trauma experiences, and specific types of traumas (sexual, physical and emotional). Setting: The study was conducted at a forensic psychiatric hospital in Johannesburg, South Africa. Methods: The records of state patients admitted over a 21-year period on a charge of murder were reviewed and analysed with respect to sociodemographic variables, clinical profiles, trauma experience and victim characteristics. Results: Experience of trauma in this population, with a much higher number of males compared with females, was lower than previous studies. Neurocognitive disorder was significantly associated with physical trauma. Physical trauma was found to have a significantly negative association with psychotic disorders, compared with other mental disorders. Conclusion: Although trauma is common in psychiatric patients, the study's findings are lower than previous studies. Noting the male bias in state patients that commit murder, greater sample sizes are needed to adequately address issues of specific types of traumas, the development of mental illness and murder. Contribution: Exploring and managing prior trauma in state patients who commit murder is important while considering rehabilitation efforts, such that reintegration into the community and non-recidivism are encouraged.

ASSOCIATION BETWEEN LEUKOCYTES COUNT AND THE SEVERITY OF COVID-19 INFECTION.

OBJECTIVE: The aim: To find an association of COVID-19 on different types of leukocytes either count increasing or decreasing. PATIENTS AND METHODS: Materials and methods: A cross sectional study conducted from October /2020 to January /2021. Eighty patients out of 170 were enrolled in this study, who were attended a private clinic for clinical investigation and a private laboratory for laboratory diagnosis of COVID-19 who were divided into two groups, asymptomatic or mild (group 1), and moderate or severe (group 2). Five milliliter of blood samples were collected from patients with COVD-19 by venipuncture using a syringe for evaluation of different cells. RESULTS: Results: The current study revealed a significant difference in white blood cells count, neutrophils count, monocytes count, basophils count, and neutrophil to lymphocyte ratio, lymphocyte to monocyte ratio between group 1 and group 2. While lymphocytes, and eosinophil showed no significant difference. CONCLUSION: Conclusion: The current study concluded that COVID-19 may affect the count of some leukocytes in patient with severe infection.

An Assessment of the Knowledge, Attitudes, and Practices of Patients and Families with Diagnoses of Hereditary Neuromuscular Disorders.

BACKGROUND: Hereditary neuromuscular disorders (NMDs) result in progressive disability with no definitive disease modifying treatments. There is a delay in diagnosis, and lack of awareness among affected individuals about these disorders, which can affect quality of life of patients. OBJECTIVE: The aim of this study is to identify gaps in patient knowledge, factors affecting attitudes toward the diagnoses, and specific practices to create better awareness among patients and healthcare providers to improve care and overall outcomes. METHODS: This is a cross-sectional study of 130 patients diagnosed with an NMD, recruited from the outpatient neurology clinics at the Aga Khan University Hospital. After telephonic consent, a 28 item survey questionnaire was administered. Knowledge, attitude, and practice scores were measured. RESULTS: One hundred and thirty of 198 study participants responded. The average age was 26.3 years; 75% were male. More than 38% (n = 50) had a middle grade or less education. The average knowledge, attitude, and practice scores were 7.9, 2.7, and 3.8 respectively. There was a low but statistically significant correlation between knowledge-attitude and attitude-practice scores. Almost 80% of respondents believed that dystrophy or spinal muscular atrophy is curable, while a majority considered that physical activity should be avoided. CONCLUSIONS: Our study presents new insights into the role of clarifying misconceptions about NMD and to correct attitudes among patients, their families and communities. It underscores the need for early interventions with demonstrably positive effects on disease progression such as physical therapy, as well as emphasizes the provision of accessible and affordable centers for such services.

OBJECTIVE: To analyse the biofilm-forming potential of clinical isolates of Staphylococcus aureus and Pseudomonas aeruginosa, and to assess antimicrobial activity of commonly used sanitizers in hospital and laboratory settings. METHODS: The study was conducted at Aga Khan University Karachi from August 2016 to January 2017. The biofilm-forming potential of Staphylococcus aureus and Pseudomonas aeruginosa clinical isolates were evaluated qualitatively using air-liquid interface tube method, and air-liquid interface cover slip assay. The antimicrobial activity of commonly-used hand-washes and sanitizers were assessed using agar well diffusion method, while the anti-biofilm activity of the hand-washes and sanitizers was qualitatively assessed using air-liquid interface covers lip as s ay. RESULTS: Of the eight hand-washes and sanitizers, 2(25%) showed antimicrobial activity against both Staphylococcus aureus and Pseudomonas aeruginosa, while 2(25%) exhibited antimicrobial activity against either S. aureus or P. aeruginosa. Also, 4 (50%) of them showed no inhibitory activity against S. aureus and P. aeruginosa. CONCLUSIONS: The findings shall have important consequences with regards to infection control in hospital and laboratory settings.

The Impact of Virtual Residency Interviews on the Geographic Distribution of Integrated Interventional and Diagnostic Radiology Residency Matches.

PURPOSE: To characterize how the adoption of virtual residency interviews (2020-2021 cycle) has impacted the geographic distribution of radiology resident matches. METHODS: University-based interventional (IR) and diagnostic radiology (DR) residency programs from 2017 to 2021 were identified using a national residency database (FRIEDA). Public applicant data were obtained from official residency program websites. Medical schools and residency programs were categorized by US census regions. Geographic applicant distribution before and after the initiation of virtual interviews was statistically assessed using Chi-square tests. The effect of virtual interviews on the probability of matching within the same geographic region as one's medical school was evaluated with multivariate logistic regression. RESULTS: 4358 radiology residents (88% diagnostic, 12% interventional) matched at 102 radiology programs during the study period. 71% (n = 3115 residents) had data available for analysis. 56.3% of DR and 49.3% of IR residents matched in the same geographic region as their medical school. The geographic distribution of applicants who matched at Southern IR residency programs significantly changed after implementation of virtual interviews (p < 0.0001). Virtual interviews did not increase the odds of matching in the same region as one's medical school for IR (OR 1.11, p = 0.08) or DR (OR 1.01, p = 0.58) applicants. Top-20 ranked DR programs had lower odds of in-region matches (OR 0.87, p < 0.001). CONCLUSION: With few exceptions, shifting to virtual residency interviews did not significantly affect the geographic distribution of IR or DR residency matches. Top-ranked DR programs match more regionally diverse applicants.

Assessing the impacts of L-carnitine and modafinil on fatigue in Iraqi multiple sclerosis patients.

Fatigue is a prevalent symptom experienced by individuals diagnosed with multiple sclerosis (MS), which greatly affects their daily activities and causes frustration and depression, thus affecting their lives and society. This can be prevented through the use of medicines such as L-carnitine and modafinil. The study aimed to examine the effect of L-carnitine and modafinil on fatigue and which one is better for MS patients. This was a clinical trial. This clinical trial was conducted in cooperation between Al-Kut University College and an MS consultant at Al-Zahraa Teaching Hospital in addition to the private neurological clinic from October 1, 2022, to March 15, 2023. Forty participants were split into two groups; both of which were almost identical characteristics regarding age, disease duration, and degree of fatigue. Group I (n = 20): relapsing-remitting MS patients with fatigue received modafinil. Group II (n = 20): relapsing-remitting MS patients with fatigue received L-carnitine. Fatigue was evaluated according to the Modified Fatigue Impact Scale (MFIS). The statistical work was done in SPSS (IBM Corp., Chicago, IL, USA, version 24). P values were calculated by the t-test. Significant data have P = 0.05. After 2 months of treatment, the results show a significant decrease in MFIS in both groups with a higher reduction in patients who use L-carnitine. Both modafinil and L-carnitine show a significant influence on fatigue in MS patients, and these effects are more in L-carnitine.

A novel automated Parkinson's disease identification approach using deep learning and EEG.

The neurological ailment known as Parkinson's disease (PD) affects people throughout the globe. The neurodegenerative PD-related disorder primarily affects people in middle to late life. Motor symptoms such as tremors, muscle rigidity, and sluggish, clumsy movement are common in patients with this disorder. Genetic and environmental variables play significant roles in the development of PD. Despite much investigation, the root cause of this neurodegenerative disease is still unidentified. Clinical diagnostics rely heavily on promptly detecting such irregularities to slow or stop the progression of illnesses successfully. Because of its direct correlation with brain activity, electroencephalography (EEG) is an essential PD diagnostic technique. Electroencephalography, or EEG, data are biomarkers of brain activity changes. However, these signals are non-linear, non-stationary, and complicated, making analysis difficult. One must often resort to a lengthy human labor process to accomplish results using traditional machine-learning approaches. The breakdown, feature extraction, and classification processes are typical examples of these stages. To overcome these obstacles, we present a novel deep-learning model for the automated identification of Parkinson's disease (PD). The Gabor transform, a standard method in EEG signal processing, was used to turn the raw data from the EEG recordings into spectrograms. In this research, we propose densely linked bidirectional long short-term memory (DLBLSTM), which first represents each layer as the sum of its hidden state plus the hidden states of all layers above it, then recursively transmits that representation to all layers below it. This study's suggested deep learning model was trained using these spectrograms as input data. Using a robust sixfold cross-validation method, the proposed model showed excellent accuracy with a classification accuracy of 99.6%. The results indicate that the suggested algorithm can automatically identify PD.

Does a Gluten-Free Diet Improve Quality of Life and Sleep in Patients with Non-Coeliac Gluten/Wheat Sensitivity?

INTRODUCTION: The role of a gluten-free diet (GFD) in Non-Coeliac Gluten/Wheat Sensitivity (NCGWS) is unclear. We present the largest study comparing adherence to a GFD in patients with Coeliac Disease (CD) and NCGWS and assess its impact on quality of life (QoL) and sleep in patients with NCGWS. METHODS: Patients with NCGWS at a tertiary centre completed the Coeliac Disease Adherence Test (CDAT), Coeliac Symptom Index (CSI) and Sleep Condition Indicator (SCI). Higher CDAT scores indicate worse adherence, higher CSI scores indicate poorer QoL, and higher SCI scores indicate better sleep. CDAT scores were correlated with CSI and SCI scores. A second group of patients with CD completed the CDAT questionnaire only. Results were compared with the CDAT responses from the NCGWS group. RESULTS: For the NCGWS cohort (n = 125), the median CDAT score was 17/35, indicating poor adherence. The median CSI score was 44/80, with 40% of scores associated with a poor QoL. The median SCI score was 14/32, and DSM-V criteria for insomnia was met by 42% of patients. There was a positive correlation between CSI and CDAT scores (r = 0.59, p < 0.0001) and a negative correlation between SCI and CDAT scores (r = -0.37, p = 0.0002). In the CD cohort (n = 170), the median CDAT score was 13/35. Patients with NCGWS had poorer adherence compared to CD (CDAT: 17.0 vs. 13.0, respectively, p = 0.0001). CONCLUSION: Patients with NCGWS adhere to a GFD less than those with CD. Poorer adherence to a GFD in patients with NCGWS correlates with a worse QoL and sleep performance.

Ebolavirus Species-Specific Interferon Antagonism Mediated by VP24.

Members of the Ebolavirus genus demonstrate a marked differences in pathogenicity in humans with Ebola (EBOV) being the most pathogenic, Bundibugyo (BDBV) less pathogenic, and Reston (RESTV) is not known to cause a disease in humans. The VP24 protein encoded by members of the Ebolavirus genus blocks type I interferon (IFN-I) signaling through interaction with host karyopherin alpha nuclear transporters, potentially contributing to virulence. Previously, we demonstrated that BDBV VP24 (bVP24) binds with lower affinities to karyopherin alpha proteins relative to EBOV VP24 (eVP24), and this correlated with a reduced inhibition in IFN-I signaling. We hypothesized that modification of eVP24-karyopherin alpha interface to make it similar to bVP24 would attenuate the ability to antagonize IFN-I response. We generated a panel of recombinant EBOVs containing single or combinations of point mutations in the eVP24-karyopherin alpha interface. Most of the viruses appeared to be attenuated in both IFN-I-competent 769-P and IFN-I-deficient Vero-E6 cells in the presence of IFNs. However, the R140A mutant grew at reduced levels even in the absence of IFNs in both cell lines, as well as in U3A STAT1 knockout cells. Both the R140A mutation and its combination with the N135A mutation greatly reduced the amounts of viral genomic RNA and mRNA suggesting that these mutations attenuate the virus in an IFN-I-independent attenuation. Additionally, we found that unlike eVP24, bVP24 does not inhibit interferon lambda 1 (IFN-λ1), interferon beta (IFN-ß), and ISG15, which potentially explains the lower pathogenicity of BDBV relative to EBOV. Thus, the VP24 residues binding karyopherin alpha attenuates the virus by IFN-I-dependent and independent mechanisms.

Evaluation of Phosphorus Storage and Performance of Broilers Using Phytase Synthetic Enzyme.

Phytic acid is a stored form of phosphorus in cereals, 65 to 70% of phosphorus in plant sources is phytate, and broilers are only able to use part of the phosphorus in plant sources. To meet the needs of chickens, it is necessary to use other artificial resources, which not only impose part of the cost of the breeding period because of its presence in the manure but is one of the factors polluting the environment. This study aimed to use different levels of phytase enzyme to reduce dietary phosphorus levels. 600 Ross 308 broilers were used in this experiment with five treatments and six replications, and in each replication, 20 chickens were used in a completely randomized design (CRD). Experimental treatments include 1) basal diet (control) 2) basal diet with 15% less phosphorus 3) basal diet with 15% less phosphorus + 1250 (FTU) phytase enzyme 4) basal diet with 15% less phosphorus + 2500 (FTU) phytase enzyme 5) basal diet with 15% less phosphorus + 5000 (FTU) phytase enzyme. The evaluated traits included weekly feed intake, weekly weight gain, feed conversion ratio, carcass characteristics, ash, calcium, and bone phosphorus. The use of phytase enzyme in different diets had no significant effect on food intake, weight gain, and feed conversion ratio (P>0.05). However, the use of phytase in different diets significantly affected the percentage of Gizzard, Heart, Liver, Proventriculus, and Spleen (P<0.05). The most changes were the increase in the ratio of feed intake and weight gain in the fourth week compared to the third week so that the changes in the ratio of feed intake ranged from 1.85 to 1.91, and this ratio for weight gain also ranged from 3.12 to 3.86 was recorded, and the lowest feed conversion ratio was obtained at the same age. The percentage of raw ash in broiler chickens was significantly increased by adding dietary phytase. The lowest amount of ash, calcium, and phosphorus belonged to the second group (diets with low phosphorus and no enzyme). The difference between the other groups and the control was not significant. Feed intake, weight gain, and feed conversion ratio with the addition of phytase enzyme were not affected by phosphorus reduction and had no significant effect on carcass characteristics. Environmental pollution can be prevented by reducing the level of dietary phosphorus and reducing excreted phosphorus.

Effect of Licorice Essential Oil (Glycyrrhizaglabraglabra) on Performance and Some Biochemical Parameters of Broiler Chickens.

Due to its beneficial components, such as glycyrrhizin, licorice is regarded a medicinal and fragrant plant. This research was designed to investigate the efficacy of licorice essential oil as an alternative to chemical antibiotics on broiler production, carcass features, cellular and humoral safety, and numerous biochemical variables in broiler blood serum. A total of 160 day-old broiler chicks were assigned to four treatment groups using a totally randomized approach. Each treatment consisted of 4 replicates, with 10 chicks in each replication. The experimental treatments included a control group, a group receiving an elemental diet containing 0.1% licorice essential oil, a group receiving an elemental diet containing 0.2% licorice essential oil, and a group receiving an elemental diet containing 0.3% licorice essential oil. Broilers had ad libitum access to feed and water in accordance with a three-phase feeding schedule consisting of a starter, grower, and finisher diet. There was no statistically significant difference (P>0.05) in body weight, feed intake, or feed conversion ratio between birds given the control or essential oil licorice at various stages of the experiment. However, birds receiving 0.1% licorice essential oil had a lower gallbladder relative weight and 0.3% licorice essential oil had less abdominal fat than the control group (P<0.05). Blood glucose, cholesterol, and LDL concentrations all fell considerably in licorice essential oil-treated birds relative to controls (P<0.05). The cellular immune response of birds fed licorice-containing diets did not differ from that of control birds (P>0.05), however there was a significant difference in the humoral immune response at 0.1% licorice essential oil compared to the control group (P<0.05). In overall, the results of this experiment demonstrated that incorporating licorice essential oil into a bird's diet improves its health and safety.

Amlodipine downregulates gene expression that involved in the signaling pathways of coagulation process in COVID-19 patients: An observational clinical study.

The SARS-CoV-2 virus has the property of activating the coagulation process, which is responsible for producing thrombotic events which is considered as one of the most serious COVID-19 complications. Hypertension is a hazard factor for COVID-19 complications, and people who are treated with calcium entry blockers may halt the occurrence of thrombotic events. to evaluate the effect of amlodipine on some genes involved in the activation of the coagulation procedure in COVID-19 patients with hypertensive. observational, cross-sectional study. This study was carried out in the Department of Pharmacy at Al-Kut University College in Wasit, Iraq, in conjunction with Al Zahraa Hospital from June 2021 to March 2022. A total of 45 COVID-19 patients participated in this study who were grouped into as follows: Group I (n = 23) who had no previous history of hypertension and Group II (n = 22) who had previous hypertension and were treated with amlodipine. Expression of the calcium-sensing receptor (CaSR), coagulation factor V (F5), and methylenetetrahydrofolate dehydrogenase (NADP+ dependent) 1 Like (MTHFD1L) genes was determined. P values were calculated by Chi-square test for categorized facts and the Mann-Whitney test for incessant data. P ≤ 0.05 was considered statistically significant. Group II patients had significantly lower levels of CaSR, F5, and MTHFD1L gene expression compared with the corresponding levels in Group I patients. The expression level of MTHFD1L was elevated significantly in patients who had currently high blood pressure compared with normotensive patients in both the groups. Amlodipine is preferred in hypertensive patients who have COVID-19 because it attenuates the levels of gene expression that have an impact on the coagulation process.

The pattern of neurological manifestations of tuberculosis among adult patients attending multineurological centres and hospitals in Sudan: A hospital-based cross-sectional study.

Background: Tuberculosis (TB) can involve almost any organ of the body. In the central nervous system (CNS), it can cause Pott's disease, meningitis, tuberculoma, abscess, or other manifestations. Tuberculosis is rampant in the developing world and has become a significant public health menace with the human immunodeficiency virus (HIV) dissemination. This study aimed to determine the frequency of neurological manifestations of tuberculosis among adult Sudanese patients. Methodology: A hospital-based cross-sectional study carried out in the period from September to December 2020 at multineurological centers and hospitals in Khartoum State, including Ibrahim Malik Teaching Hospital, Alshaab Teaching Hospital, Bashier, Abu Anga, Omdurman Teaching Hospitals, included adult patients diagnosed with tuberculosis-associated neurological manifestations. The data were collected by predesigned questionnaire, and then analyzed by computer using SPSS-version 25. Results: A total of 43 patients were evaluated, male patients were 24 (55.8%) and female patients were 19 (44.2%). About 31 (72.1%) of the participants had extra-pulmonary TB and 12 (27.9%) had pulmonary and extrapulmonary TB. The neurological manifestations of tuberculosis include Pott's disease in 29 (67.4%) patients (with thoracic spine most affected part), tuberculoma was second-most, occurring in 8 (18.7%) patients (with a single lesion in most of the patients), whereas tuberculous meningitis was found in 6 (13.9%). Clinical presentation was headache in 14 (32.6%) patients, convulsions in 10 (23.3%), loss of consciousness in 9 (20.9%), hemiparesis in 7 (16.3%) patients, and paraparesis in 23 (53.5%). Cranial nerve affected in 5 (11.6%) patients. All patients received antituberculosis medication and steroids, and 10 (23.2%) received anticonvulsants. Conclusions: Neurological tuberculosis should be ruled out in any young male from an endemic area who exhibits abnormalities in motor, sensory, special sense, or higher mental function. To avoid potentially fatal complications, diagnoses and treatments should be initiated as soon as possible.

KSTAR: An algorithm to predict patient-specific kinase activities from phosphoproteomic data.

Kinase inhibitors as targeted therapies have played an important role in improving cancer outcomes. However, there are still considerable challenges, such as resistance, non-response, patient stratification, polypharmacology, and identifying combination therapy where understanding a tumor kinase activity profile could be transformative. Here, we develop a graph- and statistics-based algorithm, called KSTAR, to convert phosphoproteomic measurements of cells and tissues into a kinase activity score that is generalizable and useful for clinical pipelines, requiring no quantification of the phosphorylation sites. In this work, we demonstrate that KSTAR reliably captures expected kinase activity differences across different tissues and stimulation contexts, allows for the direct comparison of samples from independent experiments, and is robust across a wide range of dataset sizes. Finally, we apply KSTAR to clinical breast cancer phosphoproteomic data and find that there is potential for kinase activity inference from KSTAR to complement the current clinical diagnosis of HER2 status in breast cancer patients.

Audit of Operative Notes Against Royal College of Surgeons Guidelines in a Tertiary Health Care Surgical Unit in Lahore.

Operative notes are important documentation made by the surgical team after a surgical procedure. They outline what happened during the surgery and several aspects of post-operative instructions. The aim of this audit was to compare current practices regarding documentation of these operative notes in a tertiary care hospital in Lahore. The standards used were the recommendations made in the good surgical practice guidelines by the Royal College of Surgeons (RCS) of England in 2014. A prospective closed-loop audit was conducted using a checklist constructed using the RCS guidelines. In the first audit, which was done to analyze current practices, 44 consecutive handwritten operative notes were evaluated. The findings of this initial audit were presented to the surgical team in a local meeting and recommendations were made. Forty-eight consecutive operative notes were then analyzed in the re-audit done after an interval of one month. The findings of the re-audit were presented to the surgical team. An overall 35.7% improvement was noted in the documentation of operative notes after the completion of the audit cycle. Certain parameters analyzed, such as thromboprophylaxis, antibiotic prophylaxis, and anticipated blood loss, were much more frequently documented in the re-audit. In our study, implementation of recommendations such as restructuring of the operative notes pro forma and improving awareness regarding the RCS guidelines significantly improved the quality of operative notes that were being documented. Such audits should be conducted regularly to maintain and improve the standards of documentation in all surgical units.

Energy, exergy, environmental impact, and economic analyses of evacuated tube compound parabolic concentrator-powered solar thermal domestic water heating system.

In the reported study, a dynamic analytical model is developed to propose the energy, exergy, environmental impact, and economic analyses of the water heating system at Jaipur (India) with an evacuated tube compound parabolic concentrator field of a total area of 81 m2. Consequently, the model is used to perform parametric studies to report the effect of operating and meteorological parameters on the productivity and performance of the system. Moreover, the system's performance, environmental impact, and economic aspects have been investigated and compared under different meteorological conditions at four different Rajasthan (India) locations using TMY2 weather data files. Results clarified that Jodhpur receives the highest solar radiation intensity from these four locations. The model results were validated with the experimental data, and a good agreement has prevailed. Consequently, the results indicate the highest annual energy and exergy gain for Jodhpur with 79.72 MWh and 9.311 MWh, respectively, followed by Jaisalmer, Barmer, and Jaipur. The economic analysis results clarified that the simple payback period ranged from 4.5 to 4.75 years and the discounted payback period ranged from 6.6 to 7 years based on a 6% discount rate. At the same time, the levelized cost of heating for the given system is around 0.023 $/kWh which is very economical closest to that of CNG as a fuel which costs around 0.059 $/kWh. The internal rate of return is reported to be 16.76, 16.82, 16.77, and 16.75% for Barmer, Jodhpur, Jaipur, and Jaisalmer, respectively, and savings of 74.4, 78.1, 75.4, and 73.8 tonnes of CO2 emission to the environment.

The effect of Favipiravir on liver enzyme among patients with mild to moderate COVID-19 infection: A prospective cohort study.

Teratogenicity and hyperuricemia are considered as the major adverse effects of favipiravir, but less is known about other possible side effects which includes drug-induced liver damage and renal injury. In the current research, assessment of favipiravir-induced liver injury was performed by evaluating liver enzymes among patients with mild to moderate COVID-19 infection. A prospective cohort study was conducted on 66 patients diagnosed with mild to moderate COVID-19 infection who were treated with favipiravir for 5 days. During this period, a baseline assessment of liver enzymes (aspartate aminotransferase - AST, alanine transaminase - ALT and alkaline phosphatase - ALP) in addition to bilirubin before initiation of therapy and after 1 day of completion of therapy were carried out. The comparison of all measured parameters among all patients before and after receiving the treatment showed that non-significant differences were obtained in their levels. It was noticed that COVID-19 patients demonstrated high AST levels in which only 16 patients out of the all-subjected cases (66 patients) had AST levels of less than 45 U/L whereas the majority of patients showed normal ALT, ALP, and bilirubin levels. It was concluded that 5 days administration of favipiravir in mild to moderate COVID-19 patients who had no previous liver diseases did not affect the liver enzymes significantly and only transient elevations were occurred.

Toward Personalized DAPT: Is There an Inter-Manufacturer Difference in Generic Clopidogrel Response?

OBJECTIVE: To compare rates of clopidogrel response among patients receiving medication produced by 2 different manufacturers after acute coronary syndrome (ACS) and/or percutaneous coronary intervention. METHODS: This quality-improvement project included 515 adult patients receiving clopidogrel for ACS or ischemic heart disease and referred for coronary angiography/ percutaneous coronary intervention. The project was divided into 2 phases: (1) retrospective collection of baseline data (April 2019-October 2020); and (2) two 12-week, prospective phases in which all clopidogrel in the hospital was restricted to a single manufacturer at a time (November 2020-May 2021). The primary outcome was clopidogrel response measured by platelet function testing, defined as adenosine diphosphate (ADP) response <40% on light transmission aggregometry. RESULTS: Of 515 total patients included in both phases (mean age, 64.5 ± 11.4 years; 351 men [68.2%]; 450 with ACS [87.4%]), 52% were found to be clopidogrel responders based on results of platelet function testing. Among 135 patients in the prospective phase, there was a significantly lower proportion of patients who were clopidogrel responders in the Manufacturer 1 group compared with the Manufacturer 2 group (34.8% vs 55.1%, respectively; P=.03). After adjustment for age, sex, body mass index, aspirin response, therapeutic hypothermia, left heart catheterization indication, clopidogrel loading dose, time between loading dose and lab measurement, and manufacturer, aspirin response (odds ratio 0.96; 95% confidence interval, 0.95-0.97; P<.001) and manufacturer (odds ratio, 2.45; 95% confidence interval, 1.18-5.22; P=.02) were associated with clopidogrel response. CONCLUSIONS: In a large public hospital, we observed that pharmacodynamic response to clopidogrel varied by drug manufacturer. Further investigation and/or regulation is needed to minimize inter-manufacturer variability.
