Coordinately unsaturated single Fe-atoms with N vacancies and enhanced sp3 carbon defects in Fe-N(sp2)-C structural units for suppression of cancer cell metabolism and electrochemical oxygen evolution.

Installing coordinately unsaturated Fe-N-C structural units on polymer-composite-derived N-doped carbon offers highly active Fe-Nx sites for the electrochemical oxygen evolution reaction (OER) and reactive oxygen species (ROS) generation in tumor cells. An NH4Cl-driven high-temperature etching method was employed for the formation of FeSA950NC with coordinately unsaturated single Fe-atoms in an Fe-N(sp2)-C structural unit together with N vacancies (VN) and sp3 defects. The carbonization of Fe-phen@ZIF-8 at 800 °C for 30 min under argon, followed by grinding Fe-ZIF-8@RF-urea with NH4Cl at 950 °C for 2 hours, resulted in sp3 carbon defects and VN sites with coordination unsaturation in Fe-Nx due to NH4Cl decomposition to NH3 and HCl, which produced substantial internal stress for etching the carbon matrix. FeSA950NC was used to treat both A549 lung cancer cells and NIH3T3 mouse fibroblast cells to determine its potential as an efficient tumor therapeutic strategy using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and ROS assays. Additionally, FeSA950NC provided high stability and excellent OER activity through the Fe-N(sp2)-C structural unit on pyridinic nitrogen by delivering at a minimum overpotential of 300 mV, which is much lower than that of structurally similar Fe-atom sites. The significantly stronger ROS and OER activities of FeSA950NC suggested the role of VN and sp3-carbon defects with coordinately unsaturated Fe-N2 sites in improving its catalytic performance.

Clinical outcomes following hospitalization for COVID-19 in patients with cardiac sarcoidosis in the United States: a propensity-matched analysis from national inpatient sample database from April 2020 to December 2021.

Background: The highly arrhythmogenic nature of cardiac sarcoidosis (CS) leads to high morbidity and mortality, the rates of which may be higher in COVID-19 patients. This study aimed to evaluate the outcomes of CS patients admitted to hospitals with COVID-19. Methods: The study utilised the 2020-2021 National Inpatient Sample database, examining primary COVID-19 cases in adults aged older than or equal to 18 years. Those with CS were identified using ICD-10 code "D86.85" and compared with and without propensity matching (1:10) to those without CS for baseline characteristics and primary outcomes of acute kidney injury (AKI), use of mechanical ventilation, cardiac arrest and mortality. Results: In total, 2 543 912 COVID-19 cases were identified. Before propensity matching, CS patients were more likely to be younger (58.0 vs. 64.0 years, P<0.01), male (64.0% vs. 52.6%, P=0.011), of Black ethnicity (60.0% vs. 15.9%, P<0.01), exhibit higher Charlson Comorbidity Index (CCI) scores (3.00 vs. 1.00, P<0.01) and had a higher incidence of in-hospital cardiac arrest (aOR 2.649, 95% CI 1.366-5.134, P=0.004). After propensity matching (CS, N=95; non-CS, N=875), those with CS were at a statistically significant reduced risk of AKI (aOR 0.484, P=0.01); however, the outcomes of death, cardiac arrest, mechanical ventilation, length of stay (LOS) and healthcare costs did not reach significance. Conclusion: In a propensity-matched cohort admitted with COVID-19, CS patients had a reduced risk of AKI, but comparable LOS, rates of cardiac arrest, mechanical ventilator use, and mortality. Future research is warranted to develop evidence-based guidelines for managing COVID-19 in patients with CS.

Bladder Adjuvant Radiation Therapy (BART): Acute and Late Toxicity From a Phase III Multicenter Randomized Controlled Trial.

PURPOSE: To report toxicity from the multicenter phase III randomized trial of Bladder Adjuvant Radiation Therapy (BART) after radical cystectomy and chemotherapy in high-risk muscle-invasive bladder cancer (MIBC). METHODS AND MATERIALS: Patients with nonmetastatic urothelial MIBC with ≥1 high-risk feature after radical cystectomy- pT3-4, pN1-3, nodal yield <10, positive margin, or ≥cT3 downstaged with neoadjuvant chemotherapy- were randomized 1:1 to observation (Obs) or adjuvant radiation therapy (RT) at 4 centers, stratified by pN stage (N0, N+) and chemotherapy (neoadjuvant, adjuvant, none). Stoma-sparing image guided intensity modulated RT 50.4 Gy in 28# was prescribed to the cystectomy bed and pelvic nodes. Acute toxicity (≤3 months of RT/randomization) and late toxicity were assessed per protocol using Common Terminology Criteria for Adverse Event v5.0. Patients progressing within 3 or 6 months of randomization were excluded from acute or late toxicity analysis, respectively. RESULTS: The BART trial enrolled 153 patients (Obs = 76, RT = 77). About half (49%) had pN+. Nearly 90% received chemotherapy (70% neoadjuvant; most commonly gemcitabine plus cisplatin). In the RT arm, 63/77 completed RT per protocol with no toxicity-related RT termination. Of the 134 patients analyzable for acute toxicity, no difference was observed in grade 3 (Obs 4.2% vs RT 1.6%, P = .34). Grade 2 effects were higher with RT (17.5% vs 1.1%, P < .001), mainly diarrhea/enteritis or proctitis. Late toxicity was analyzable for 104 patients (Obs = 57, RT = 47) with a median follow-up of 27 months. Grades 3 to 4 toxicity were about 10% (Obs 10.5% vs RT 8.4%, P = .62), and cumulative late grade 2+ toxicity was similar in both groups (17.5% vs 23.3%, P = .27). CONCLUSIONS: In the largest trial of adjuvant RT for high-risk urothelial MIBC, severe acute and late toxicity were low and similar with obervation or radiation therapy. The oncological outcomes are awaited.

Melanoma Cell Adhesion Molecule (CD 146) in Endometrial Physiology and Disorder.

The human endometrium, the innermost lining of the uterus, is the anatomic prerequisite for pregnancy. It is the only dynamic tissue that undergoes more than 400 cycles of regeneration throughout the reproductive life of women. Key to this function are endometrial stem cells as well as cell adhesion molecules. Melanoma cell adhesion molecule (MCAM/CD146/MUC18) is a membrane glycoprotein of the mucin family and a key cell adhesion protein, highly expressed by endometrial cells. CD146 is a significant molecule pivotal in endometrial physiology, assisting tissue regeneration and angiogenesis. Endometrium also acts as a culprit in causing several endometrial dysfunctions, such as endometriosis, endometrial hyperplasia, and endometrial carcinoma, due to interrupted molecular and functional mechanisms. Though most of the endometrial dysfunctions arise as a result of endocrine disturbance, it has a major pathological role associated with angiogenesis. It has already been proven that CD146 is a potential marker for the diagnosis of angiogenic dysfunctions and malignancy, including endometrial cancer. However, its mechanistic role in causing the pathology is a mystery. This chapter explores the role of CD146 in normal and pathological endometrial conditions and the therapeutic implications of CD146.

Outcomes of cardiac resynchronization therapy (CRT) in cardiac sarcoidosis patients with a range of ejection fractions.

AIMS: In cardiac sarcoidosis (CS) patients, the benefit of cardiac resynchronization therapy (CRT) remains unclear. We sought to assess the short-term and long-term effects of CRT in CS patients with a range of left ventricular (LV) ejection fractions (LVEFs). METHODS: Consecutive CS patients with heart failure with reduced ejection fraction (HFrEF; LVEF ≤ 40%), mildly reduced ejection fraction (HFmrEF; LVEF 41%-49%) and preserved ejection fraction (HFpEF; LVEF ≥ 50) treated with CRT under the care of a tertiary UK centre between 2008 and 2023 were reviewed. CRT response was defined by >5% improvement in serial LVEF. The primary endpoint was a composite of all-cause mortality, cardiac transplantation or unplanned hospitalization for decompensated heart failure. The secondary endpoint included ventricular arrhythmic events. RESULTS: Of the 100 patients enrolled (age 58 ± 10 years; 71% male), 63 had HFrEF, 17 had HFmrEF and 20 had HFpEF. After short-term follow-up (9.8 ± 5.4 months), HFrEF patients demonstrated significant LVEF response (P < 0.01). On Kaplan-Meier analysis (follow-up 38 ± 32 months), HFrEF non-responders had significantly worse event-free survival compared with HFrEF responders for the primary (P < 0.001) and secondary (P = 0.001) endpoints. Despite short-term LV function improvement, CRT responders still had worse event-free survival compared with HFmrEF/HFpEF patients for the primary endpoint (P < 0.001). On multivariable Cox analysis, age [hazard ratio (HR) 1.05, 95% confidence interval (CI) 1.01-1.10, P = 0.008] and HFrEF CRT non-response (HR 12.33, 95% CI 2.45-61.87, P = 0.002) were associated with the primary endpoint. CONCLUSIONS: In CS patients with HFrEF, CRT response is associated with a better long-term prognosis than non-response. However, HFrEF CRT responders still have worse long-term prognosis than HFmrEF/HFpEF patients.

A mixed-method study to develop and evaluate a structured therapeutic communication module on psychological distress and perceived needs among caregivers of critically ill patients in Critical Care Units.

AIMS AND OBJECTIVES: To develop and evaluate the effectiveness of a structured therapeutic communication module on psychological distress and perceived needs among caregivers of critically ill patients. BACKGROUND: Caregivers of critically ill patients experience intense psychological distress, and their needs often go unexpressed or unidentified. Structured therapeutic communication enables nurses to explore and fulfill these needs. METHOD: A mixed-method study was conducted among 30 caregivers of critically ill patients. During phase one, a qualitative interview was conducted, and a structured therapeutic communication module was developed based on Hildegard Peplau's Interpersonal Relations Theory. In the second phase, one group pre-test and post-test design was adopted. The Hospital Anxiety and Depression Scale (HADS) and a Semi-structured interview schedule were used to assess psychological distress and perceived needs, respectively. RESULTS: Half of (50 %) the caregivers reported a high level of anxiety before intervention, with a mean of 11.30 (SD: 4.0), and 66.7 % of them had a high level of depression, with a mean of 12.03 (SD: 0.08). There was a statistically significant difference in anxiety (CI: 0.451-2.016) and depression (CI: 0.261-1.538) before and after the intervention. The qualitative analysis revealed unmet needs perceived by caregivers. CONCLUSION: Using a structured therapeutic communication module helps nurses to alleviate the psychological distress experienced by caregivers of CCU patients. RELEVANCE TO CLINICAL PRACTICE: Nurses need to be sensitive to the unexpressed needs of caregivers of critically ill patients. The structured therapeutic communication modules can be integrated into routine nursing care practice to ensure family-centered care.

Indocyanine green and methylene blue dye guided sentinel lymph node biopsy in patients with penile cancer (PeCa): results of 50 inguinal basins assessed at a single institution in India.

AIM: The primary aim of this study was to validate the reliability, sensitivity and safety profile of novel combination of ICG- methylene blue dye as an SN tracer for PeCa. METHODS: This is a validation and non-randomised prospective observational study involving 25 patients (50 inguinal basins) who underwent SLNB where in ICG and methylene blue were used for localisation. The patients with clinically node negative groins were recruited in the study. SNs were identified intraoperatively using near infrared fluorescence imaging (NIRF Imaging system, SPY-PHI, Stryker, Sweden) and blue dye. The numbers of SNs identified by each tracer and the rates of complications and nodal recurrence during the followup. RESULTS: Overall 137 SNs were identified intraoperatively. Among the 137 SNs excised fluorescence, blue dye and Combined (blue + green) identified 57(41.6%), 27 (19.7%), and 51 (37.2%), respectively. The average number of SLNs removed per patient was 5 (range, 1-11) with sentinel lymph nodes detection rate at 94% (47/50). Seven patients had malignancy on SLNB and underwent ipsilateral radical inguinal lymphadenectomy. One patient had false negative SN and positive node in modified inguinal lymphadenectomy specimen. No adverse events were observed in all cases. CONCLUSION: The Novel combination of ICG fluorescence-Methylene blue dye technique is simple, reliable and safe. Moreover, it demonstrates a high SLN detection rate with a low false-negative rate, and it avoids radiation exposure.

Characterization and angiogenic potential of CD146+ endometrial stem cells.

BACKGROUND: The human endometrium, lining the inner uterus, regenerates over 400 times uniquely during a woman's reproductive life. Endometrial stem cells (eSCs) enrich the tissue, resulting in a dense vascular network, significant angiogenic potential, and effective regeneration power. Being of natural angiogenic properties and proven effective in the treatment of vascular disorders, eSCs can be considered safe, reliable, and superior to other post-natal stem cells. Cluster of Differentiation 146 (CD146) has emerged as a pivotal marker associated with pericytes and endothelial cells for promoting angiogenesis. Endometrial cells with high CD146 expression could proliferate and differentiate into multiple lineages. This study will explore the role of CD146 in eSCs, focusing on the potential to boost the angiogenic and regenerative functions of the cells. The novelty of this study lies in the investigation of CD146 on eSC function, which may open new possibilities for eSC-based therapy in regenerative medicine and vascular disorders. METHODS: The study involved obtaining endometrial biopsies from active reproducing women to isolate and cultivate eSCs. eSCs were assessed for growth factor secretion pattern, characterized for their mesenchymal properties. Finally, eSCs were tested for their angiogenic potential by angiogenic gene expression profile and in-ovo chick embryo model. As aimed, to check the role of CD146 in eSC angiogenesis, CD146+ cells were magnetically sorted and cultured. The sorted cells underwent various analyses, including flowcytometry to identify mesenchymal markers and human growth factor panel to analyze growth factor secretion profiles The study evaluated the angiogenic potential of CD146 + cells using functional assays, including ring formation, endothelial differentiation, and wound scratch assays, to evaluate cell migration and healing capabilities. Molecular insights were obtained through chemokine and cytokine investigations In-ovo Chick model assay was conducted to check the angiogenic potential and evaluated through macroscopic as well as through immunohistochemistry. RESULT: Endometrial stem cells (eSCs) were successfully isolated using a combination of mechanical and enzymatic digestion, followed by culturing in complete DMEM media. The secretion profile of eSCs revealed significant production of various angiogenic growth factors, including Granulocyte macrophage colony-stimulating factor (GM-CSF), granulocyte colony stimulating factor (G-CSF), Vascular endothelial growth factor (VEGF), Fibroblast growth factors (FGF), and Platelet derived growth factor AA (PDGF-AA). The angiogenic gene profile indicated upregulation of several angiogenic genes in eSCs. The mesenchymal nature of eSCs was demonstrated through surface marker analysis (Cluster of differentiation 73, Cluster of differentiation 90, Cluster of differentiation 105) and trilineage differentiation. The in-ovo chick model confirmed the angiogenic potential of eSCs. CD146+ cells, isolated via magnetic sorting, exhibited enhanced angiogenic potential. These cells secreted significant levels of angiogenic growth factors such as VEGF. In Matrigel assays, CD146+ cells formed endothelial ring structures more rapidly and persistently than unsorted eSCs. Semi-quantitative PCR confirmed their endothelial differentiation. CD146+ cells express various angiogenic chemokines such as CXCL5, CXCL8, CCL3, and CCL20 and cytokines such as GM-CSF, Interleukin-1ß (IL-1ß), Interleukin-6 (IL-6), PDGF AA/BB, Epidermal growth factor (EGF), Endothelin 1, Angiopoietin. In-ovo chick model assay showed that CD146+ cells had superior angiogenesis, with more nodes, junctions, and segments compared to eSCs and controls. Immunohistochemistry confirmed increased expression of endothelial markers (Cluster of differentiation 31, VEGF, Vascular associated protein (VAP), Von Willebrand factor (vWF) in CD146+ cells. CONCLUSION: The study highlights the angiogenic potential of endometrial stem cells, particularly the CD146+ cell population. These cells promote angiogenesis, secreting growth factors and forming stable blood vessel structures. CD146+ cells have higher expression levels of VEGF and TGF-α, key factors in angiogenesis. This suggests CD146+ eSCs may be promising for therapeutic applications in vascular diseases requiring angiogenesis. Further research is needed.

Empathy development through game-based learning: An investigative study on nursing professionals.

BACKGROUND: Empathy is at the core of patient-centred care. Evidence has continually found that empathy helps foster therapeutic relationships and is essential in the delivery of quality healthcare. In India, many factors are barriers to empathy for nursing professionals. OBJECTIVES: DESIGN AND METHODS: The IDEO design thinking process was followed to design the game. A focus group discussion with 18 nurses helped identify relevant scenarios and barriers to empathy. A scenario of an interaction between a nurse and a cancer patient was identified to create the game. The game mechanics, rubrics, and scenarios were built based on feedback from diverse professionals consisting of doctors, nurses, and UX designers. A learner feedback form assessing usability, contextual specificity, engagement, and perceived learnability was created and its reliability was tested. The game was tested on 60 nurses, followed by administration of the learner feedback form. To assess changes in empathy, an empathy scale was administered before the intervention and seven days after the intervention on 20 nurses. RESULTS: The learner feedback form was found to have Cronbach's Alpha >0.70, and therefore reliable. The responses to the learner feedback form were analysed using the Chi Square test and were found to be positive and statistically significant (p-value<0.001). The differences in pretest and posttest empathy scores were analysed using the Wilcoxon Signed Ranks test and were found to be statistically significant as well (p-value<0.001). CONCLUSIONS: The positive response to the learner feedback form, and the improvement in empathy scores after the intervention, indicates that games have a potential role in teaching empathy to Nursing Professionals.

Adverse pregnancy outcomes in maternal malarial infection: A systematic review and meta-analysis.

Background: Malaria in pregnancy is a critical public health issue that can lead to severe adverse outcomes for both mother and fetus. This systematic review and meta-analysis evaluated the prevalence of adverse birth outcomes in malaria-infected pregnancies and examines their association with the condition. Method: We searched databases up to January 30, 2024, for observational studies on pregnant women with malaria. Data were analyzed using a random-effects model to calculate pooled prevalence rates and risk ratios (RRs) for adverse outcomes, with statistical support from R software version 4.3. Results: Thirty-one studies were included, showing high prevalence of low birth weight (LBW; 17.4 %), preterm birth (17.9 %), and small for gestational age (SGA; 16.1 %) in malaria-affected pregnancies. Infected mothers were significantly more likely to have LBW infants (RR = 1.755), preterm births (RR = 1.484), and SGA infants (RR = 1.554). The risk of stillbirth was not significantly increased (RR = 1.238). Conclusion: Malaria in pregnancy significantly elevates the risk of LBW, preterm birth, and SGA, underscoring the need for effective malaria prevention and treatment strategies in endemic regions. Future research should aim to refine and implement these strategies to enhance maternal and neonatal health outcomes.

Outcomes of definite vs probable/presumed cardiac sarcoidosis: a systematic review and meta-analysis.

BACKGROUND: Diagnosing cardiac sarcoidosis (CS), which can be associated with arrhythmias and heart failure, remains challenging despite multiple advances over time. The 2014 Heart Rhythm Society (HRS) consensus statement recommends an endomyocardial biopsy (EMB) to establish a definite diagnosis of CS. In the absence of a positive EMB, a diagnosis of probable or presumed CS is made on the basis of clinical and imaging criteria. OBJECTIVE: To investigate whether there is any difference in outcomes between definite vs probable/presumed CS. METHODS: PubMed/MEDLINE, Embase, and the Cochrane Library databases were searched for relevant studies published after 2014. Risk ratios (RR) with 95% confidence intervals (CI) were calculated using the random effects model and presented in forest plots. RESULTS: 6 studies involving 2,204 patients were identified. The cohort had a mean age of 56.8 years (SD: ±13.6 years). The median duration of follow-up was 40.5 months. No statistically significant difference was observed between definite and probable/presumed CS for reduced risk of the composite endpoint (RR: 1.80, 95% CI: 0.93 to 3.49), and all-cause death (RR: 1.01, 95% CI: 0.48 to 2.10). CONCLUSION: This meta-analysis demonstrated the equivalence of clinical course and prognosis between definite and probable/presumed CS. This highlights the importance of a multi-disciplinary approach to CS care and emphasizes that histological confirmation should not be a prerequisite to diagnose or manage this condition.

Liquid drop interferometry on reflective surfaces.

We resolve the main bottleneck of achieving optimal fringe contrast on highly reflective surfaces through the innovative application of rear surface mirrors, unveiling a pioneering approach to precision measurements exemplified by the modified liquid drop interferometry (LDI) technique. By utilizing a liquid drop on a highly reflective surface, the need for a reference lens with a specific coating is eliminated, showcasing the technique's versatility. Furthermore, we first validate a novel, to our knowledge, expression for p-polarization-dependent radiation pressure, addressing a century-old problem reported in the literature. Beyond advancing measurement techniques, this study broadens the scope of applications requiring high precision, particularly in nanotechnology and surface characterization of metallic-coated surfaces.

Assessment of Thrombotic Complications among Coronavirus Disease 2019 Positive Hospitalized Patients at One of Government Tertiary Care Centres of Gujarat: A Retrospective Observational Study.

OBJECTIVES: The objectives of the study were to (1) study risk factors of thrombotic complications in coronavirus disease 2019 (COVID-19) pneumonitis, and (2) study progression of thrombotic complications after COVID-19 pneumonitis and its outcome. MATERIALS AND METHODS: A total of 50 COVID-19-positive admitted patients were studied using a purposive random sampling method. A questionnaire was used to collect data from patients' case records. RESULTS: Diabetes (42%) and hypertension (40%) were common comorbidities. The most common presentation of patients was thromboembolism, followed by cerebrovascular accident (CVA) and myocardial infarction (MI). Around 32% of patients died during the course of treatment. Deaths were more commonly seen in the age-group of 56 years or above than in those below 56 years. Death rates were higher among the group of patients with diabetes, hypertension, and ischemic heart diseases than the group of patients without those diseases, respectively. Patients in whom intubation was needed had a higher death rate than those without the need for it. The mean C-reactive protein (CRP) value was higher in patients who died than in those who survived. The death rate was lower in patients who were thrombolysed than in those who were not, in both pulmonary embolism and MI cases. CONCLUSION: The most common age-group admitted to the hospital was 46-55 years. The two most common underlying risk factors were diabetes and hypertension. Three common presentations of patients were thromboembolism, followed by CVA and MI. Around 32% of patients died during the course of treatment. Deaths were more commonly seen in the age-group of 56 years or above than in those below 56 years. Death rates were higher among the group of patients with diabetes, hypertension, and ischemic heart diseases than the group of patients without those diseases, respectively. Patients in whom intubation was needed had a higher death rate than those without the need for it. The mean CRP value was higher in patients who died than in those who survived.

Clinical outcomes with cardiac resynchronization therapy in patients with Cardiac Sarcoidosis: A systematic review and proportional meta-analysis.

BACKGROUND: Cardiac sarcoidosis (CS) is an inflammatory condition that can present with heart failure (HF). Cardiac resynchronization therapy (CRT) is known to improve clinical outcomes for patients with left bundle branch block in the general HF population. However, data about the outcomes of CRT in CS is limited. METHODS: A systematic literature search was conducted using PubMed/Medline, Embase, and the Cochrane Library from inception to February 2024 to identify studies that reported clinical outcomes following the use of CRT in patients with CS. Data for outcomes was extracted, pooled, and analyzed. OpenMetaAnalyst was used for pooling untransformed proportions along with the corresponding 95 % confidence intervals (CIs). RESULTS: Five studies with a total of 176 CS patients who received CRT were included. The pooled incidence for all-cause mortality was 7.6 % (95 % CI: -3 % to 18 %), for HF-related hospitalizations 23.2 % (95 % CI: 2 % to 43 %), and for major adverse cerebral and cardiovascular events 27 % (95 % CI: 8 % to 45 %) after a mean follow-up of 60.1 (±48.7) months. The pooled left ventricular ejection fraction (LVEF) was 34.28 % (95 % CI: 29.88 % to 38.68 %) demonstrating an improvement of 3.75 % in LVEF from baseline LVEF of 30.58 % (95 % CI: 24.68 % to 36.48 %). The mean New York Heart Association (NYHA) functional class was 2.16 (95 % CI: 1.47 to 2.84) after CRT as compared to the baseline mean NYHA of 2.58 (95 % CI: 2.29 to 2.86). CONCLUSION: Although improvements were observed in LVEF and mean NYHA, mortality was high in CS patients with CRT.

Sex disparities in cardiac sarcoidosis patients undergoing implantable cardioverter-defibrillator implantation.

INTRODUCTION: In patients with cardiac sarcoidosis (CS), implantable cardioverter-defibrillators (ICDs) are important for preventing sudden cardiac death. This study aimed to investigate sex disparities in CS patients undergoing ICD implantation. METHODS: The 2016-2020 National Inpatient Sample (NIS) database compared the characteristics and outcomes of males and females with CS receiving ICDs. RESULTS: Among 760 CS patients who underwent inpatient ICD implantation, 66.4% were male. Males were younger (55.0 vs. 56.9 years, p < .01), had higher rates of diabetes (31.7% vs. 21.6%, p < .01) and chronic kidney disease (CKD) (16.8% vs. 7.8%, p < .01) but lower prevalence of atrial fibrillation (AF) (11.9% vs. 23.5%, p < .01), sick sinus syndrome (4.0% vs. 7.8%, p = .024), ventricular fibrillation (VF) (9.9% vs. 15.7%, p = .02), and black ancestry (31.9% vs. 58.0%, p < .01). Unadjusted major adverse cardiovascular events (MACE), defined as a composite of in-hospital death, myocardial infarction (MI), and ischemic stroke, was higher in females (11.8% vs. 6.9%, p = .024), but when adjusted for age and tCharlson Comorbidity Index (CCI), females demonstrated significantly lower odds of experiencing MACE (aOR: 0.048, 95% CI: 0.006-0.395, p = .005). Incidence of acute kidney injury (AKI) post-ICD was significantly lower in females (15.7% vs. 23.8%, p = .01) as was the adjusted odds (aOR: 0.282, 95% CI: 0.146-0.546, p < .01). There was comparable mean length of stay and hospital charges. CONCLUSION: ICD utilization in CS patients is more common among males, who have a higher prevalence of diabetes and CKD but a lower prevalence of AF, sick sinus syndrome, and VF. Adjusted MACE and AKI were significantly lower in females.

Impact of age at first calving on fertility and production performance in Murrah buffalo.

The present study analyses the effect of age at first calving (AFC) on future fertility and productivity in Murrah buffaloes. The data of 314 buffalo heifers of animal farm section, ICAR-CIRB, Hisar were collected over a period of 9 years from 2010 to 2018. The buffalo heifers were categorized into six groups according to the AFC named as 30-35, 36-41, 42-47, 48-53, 54-59 and 60-65 months. The influence of AFC on standard lactation milk (SLMY), peak yield (PY), days in milk (DIM), calving to first service, service per conception, calving to conception interval (CCI) and calving interval till fifth lactation were studied. The study revealed poor productive traits in buffalo heifers calved at younger age (30-35 months) during first parity. The productive value positively corresponded with increase in AFC. During successive lactations, higher mean milk yield (SLMY and PY) was found in groups with 36-41, 42-47 and 48-53 months. The mean number of services per conception was lower in buffalo heifers with 36-41 and 42-47 months following first calving till fifth lactation. Similarly, the said groups had lower mean calving to first service, CCI and CI up to fifth lactation. The survival rate was higher in heifers with AFC 36-41, 42-47, 48-53 and 54-59 months than with AFC 30-35 and 60-65 months. The buffalo heifers with 36-41 and 42-47 months of AFC had higher survival rate and better productive and reproductive traits till fifth parity in the current study. The study concluded that a minimum ideal AFC of 36-41 months yielded the highest productive gain.
