Objective: To evaluate the relationship between homocysteine levels and anti-mullerian hormone (AMH) levels, a biomarker of ovarian reserve, and the effect of high homocysteine levels on ovarian reserve in subfertile women.

Study design: Observational case-control study. Place and Duration of the Study: Samsun Training and Research Hospital, Samsun, Turkiye, from October to December 2023.

Methodology: Seventy-nine subfertile women and 35 healthy fertile women were included in this study. AMH, homocysteine, thyroid stimulating hormone (TSH), free T3 (fT3), free T4 (fT4), iron, and ferritin levels of subfertile and fertile women were compared. Logistic regression, receiver operating characteristic, and Kaplan-Meier analyses were performed for homocysteine levels.

Results: AMH, fT4, iron, and ferritin levels were lower in subfertile women than in fertile women (p <0.001). Homocysteine and TSH levels were higher in subfertile women than in fertile women (p <0.001). The sensitivity for homocysteine levels was 94.90% and the specificity was 94.30%. In the Kaplan-Meier analysis, homocysteine levels of 12.90 μmol/L and above were found to be risky in terms of fertility. Homocysteine levels, AMH, and ferritin levels were negatively correlated and TSH levels were positively correlated in subfertile women (p <0.001). However, these correlations were not observed in fertile women (p >0.05).

Conclusion: High homocysteine levels can be considered as a risk factor affecting ovarian reserve in subfertile women.

Objective: To test the validity of the paediatric early warning score (PEWS) and to identify the patients with deteriorating clinical conditions who were reviewed by a rapid response team (RRT) and were advised higher level of care.

Study design: Observational study. Place and Duration of the Study: Paediatric ward and high dependency unit (HDU) of The Aga Khan University Hospital (AKUH), Karachi, Pakistan, from January 2021 to March 2022.

Methodology: All children aged 1 month to 18 years, admitted with non-surgical diagnoses at AKUH and referred for an RRT consultation were identified by non-probability consecutive sampling. The bedside nurse assessed the PEWS and alerted the clinical team. The patient's further course of action was decided based on the PEWS, detailed systemic examination, and laboratory workup. This aided in deciding the level of care (General ward, HDU, Paediatric Intensive Care Unit) required by the patients. Patients with length of stay >24 hours were included and those with did not resuscitate orders were excluded.

Results: Overall 10,032 patients were admitted to the ward and high dependency unit (HDU). Out of which, 323 (3.2%) patients had an RRT call and were included in the study. The median age of the study population was 3.15 years during the study period, and 30.3% were <1 year. System-wise admission diagnoses included respiratory (33.2%) and neurological diseases (16.1%). Median [interquartile range (IQR)] PEWS at RRT call was 2 (IQR, 1-2) on median admission day 2 (IQR, 1-3). The cumulative data at PEWS ≥3 demonstrated an area under the curve of 63% with a sensitivity of 90% and a specificity of 30%.

Conclusion: PEWS >3 can probably identify the patients at risk of deterioration with excellent sensitivity.

Objective: To evaluate and compare the blood transfusion requirements during delivery in third-trimester pregnant women with iron deficiency anaemia (IDA) who were treated with intravenous (IV) ferric carboxymaltose (FCM) versus those treated with oral iron supplementation.

Study design: Comparative study. Place and Duration of the Study: Bakirkoy Dr. Sadi Konuk Training and Research Hospital, Istanbul, Turkiye, from January 2017 to December 2022.

Methodology: Pregnant women with haemoglobin (Hb) levels <10 g/dL in their third trimester were included. One group (n = 50) received IV FCM, while the other group (n = 96) received oral iron therapy. Key outcome measures included Hb levels at delivery and the need for a postpartum blood transfusion. Inclusion criteria were third-trimester pregnancy with IDA, and exclusion criteria included haematological or chronic systemic diseases and high-risk pregnancies.

Results: The mean initial Hb levels in the third trimester of pregnancy in the FCM group and oral iron group were 8.31 ± 0.96 g/dL and 9.29 ± 1.20 g/dL, respectively (p <0.001). The mean Hb levels in the delivery room were 11.09 ± 1.38 and 9.44 ± 1.16 g/dL, respectively (p <0.001). The rates of postpartum erythrocyte transfusion requirement were 6% (n = 3) and 18.75% (n = 18), respectively (p = 0.037).

Conclusion: IV FCM administration to pregnant patients with IDA during the third trimester was found to be more effective than oral iron treatment in reducing blood transfusion rates.

Objective: To investigate the relationship between serum nesfatin-1 and insulin-like growth factor-1 (IGF-1) levels and adverse pregnancy outcomes (APOs) in patients with polycystic ovary syndrome (PCOS).

Study design: Observational study. Place and Duration of the Study: The study was performed from June 2021 to 2023 in the General Gynaecology section at the Maternity & Child Care Center of Qinhuangdao, Hebei, China.

Methodology: A total of 120 pregnant women with PCOS were divided into the control and study groups. The control group consisted of 70 pregnant women who successfully delivered healthy newborns, whereas the study group included 50 pregnant women who experienced APOs. The serum nesfatin-1 and IGF-1 levels in both groups were measured upon admission. The potential influencing factors of APOs in pregnant women with PCOS and the predictive value of serum nesfatin-1 and IGF-1 for APOs were analysed.

Results: Serum nesfatin-1 and IGF-1 levels were significantly higher in the study group than in the control group (p <0.05). Multivariate analysis revealed that testosterone ≥45 μg/L, body mass index ≥25 kg/m², waist-hip ratio ≥0.80, gestational diabetes mellitus, nesfatin-1, and IGF-1 were independent risk factors of APOs in patients with PCOS. The AUC for IGF-1 plus nesfatin-1 in predicting APOs in pregnant women with PCOS was 0.900 (95% CI: 0.845, 0.955).

Conclusion: Elevated serum nesfatin-1 and IGF-1 levels are associated with pregnancy outcomes of patients with PCOS.

Exercise instigates adaptations in structural as well as functional organisation of the body at tissue and organ levels. However, the effect of exercise on vascular wall morphology is still under investigation. The objective of the review is to provide a meta-analysis of data from the previously published research to provide compiled analysis to determine the effect of exercise on the thickness of large-sized vessel walls. This meta-analysis was executed at the Ziauddin College of Rehabilitation Sciences with an extensive literature search using databases and search engines such as Pubmed, CINAHL, Web of Science, Scopus, and Google Scholar between September 2022 and January 2023. Studies were appraised according to an estimate of mean difference and pooled effect size was calculated using a random effect model. The risk of bias was also calculated using SYRCLE's risk of bias tool and CAMARADES. Overall, five eligible pre-clinical trials using rat models with pertinent data to determine the effect of exercise on vessel wall thickness were included in the meta-analysis. The results showed that aerobic exercise significantly reduced the vessel wall thickness (SMD -0.854 5%; CI: -1.365 to -0.344; p <0.001). Moreover, no significant publication bias was found through funnel plot and statistical test (Egger's p = 0.276; Begg's p = 0.624). However, an extensive review of the literature currently available on the topic has shown mixed findings that are consistent with the study and vice versa. Therefore, it indicated the need for sub-group analysis with different types of exercises for more peculiar clinical approaches.

Objective: To determine the long-term effects of early postnatal malnutrition and various degrees of catch-up growth on metabolic (serum glucose, leptin, triacylglycerides) and neurodevelopmental parameters (learning and memory) among male and female rodent models, mimicking human preterm infants.

Study design: Randomized controlled trial. Place and Duration of the Study: CMH Multan Insitute of Medical Sciences, from September 2021 to December 2021.

Methdology: This study included 142 neonatal Wister rats, stratified into subgroups to mimic the human preterm infant model of postnatal malnutrition and catch-up growth. Metabolic consequences were assessed via serum analysis of glucose, leptin, and triacylglycerides. The neurocognitive comparison was made among subgroups via a passive avoidance test. Gender-specific comparison of all quantitative parameters was made among subgroups.

Results: Malnourished rats with accelerated catch-up growth achieved similar weight gain as normally fed rats when provided with adlibitum feeding in both males (p = 0.92) and females (p >0.99). Rats undergoing accelerated catch-up growth exhibited higher fasting serum glucose levels compared to those undergoing no, or normal catch-up growth (p <0.001). Malnourished female rats undergoing accelerated (p = 0.007), or no catchup growth (p = 0.004) exhibited significant deficits in learning and memory as compared to normally fed rats. Female malnourished rats with normal catchup growth exhibited no neurocognitive deficit as compared to normally fed rats (p = 0.08).

Conclusion: Accelerated catch-up growth effectively addresses somatic growth disparities, while normal catch-up growth offers more favourable metabolic and neurodevelopmental outcomes. Particularly, female malnourished rats exhibited poor neurodevelopment in response to both accelerated and no catch-up growth. Gender-specific variations in neurodevelopment underscore the need for personalised care approaches for preterm nutritional care.

The clinical risk factors and risk of developing pulmonary embolism (PE) in patients with acute isolated distal deep venous thrombosis (IDDVT) were assessed using single complete-duplex ultrasound (CDUS) imaging to reduce over-testing and over-treatment. This observational study was conducted from January 2020 to December 2022. Retrospective analysis was performed on CT pulmonary angiography (CTPA), blood coagulation markers, myocardial injury markers, blood gas analysis, and CDUS imaging of the lower extremity blood vessels of 146 patients with newly diagnosed IDDVT. Binary logistic regression was used to evaluate the relationship between these indicators and PE. After stepwise regression analysis, the predictors included in the regression model were D-dimer (DD), the sum of the thrombus length, and the maximum value of the thrombus width, with odds ratios (ORs) of 1.307 (p <0.001), 1.018 (p = 0.005), and 1.613 (p = 0.018), respectively. The combined prediction model achieved an area under the receiver operating characteristic curve (AUC) of 0.832 [95% confidence interval (CI): 0.761, 0.902]. By balancing the sensitivity and specificity of DD, combined single CDUS improves the predictive value for PE in patients with IDDVT.
