Relationship between aging and control of metabolic syndrome with telomere shortening: a cross-sectional study.

Aging is considered one of the major risk factors for several human disorders. The telomere plays a crucial role in regulating cellular responsiveness to stress and growth stimuli as well as maintaining the integrity of the Deoxyribonucleic Acid (DNA), and aging leads to the progressive decline in the telomere length (TL) due to continuous cell division. The aim of this study was to determine the relationship between TL and advancing age and the impact of metabolic syndrome (MetS) on TL. Firstly, we determined the association of advancing age and TL, by measuring telomere length (T/S ratio) in healthy volunteers (n = 90). The TL was compared between normal population and patients with metabolic syndrome (n = 298). The age matched controlled and uncontrolled MetS patients (n = 149) were also compared for their TL T/S ratio. The TL showed negative correlation with advancing age, whereas the significant change was observed at the cut-offs of 40 and 70 years defining 40 with longer TL and 70 as shorter TL. The longest T/S ratio at 2.46 was measured at the age range of 1 year in healthy volunteers, while elderly population showed considerably shorter TL. The patients older than 60 years with poor or uncontrolled MetS had shorter TL, as compared to the controlled MetS. In conclusion our findings suggest that TL was negatively correlated with advancing age. Uncontrolled metabolic syndrome appeared to have worsening effects on TL. Telomere length appears to have potential to be used a parameter to determine age. However, further large scale studies are recommended to make firm guidelines.

Impact of ACE2 gene variations on COVID-19 pathogenicity in Pakistani patients.

Background: COVID-19, caused by the SARS-CoV-2 virus, swiftly disseminated and was declared a pandemic. Variations in the ACE2 gene can impact the virus's ability to bind to ACE2 receptor, potentially influencing an individual's susceptibility and its association with COVID-19 severity across various populations. Methods: In total, 200 individuals were sequenced for the ACE2 gene and potential impact of the found variants on the ACE2 protein was assessed using in-silico tools. Results: Eight variations in the ACE2 gene were identified in 27 COVID-19 patients, of which four were missense and four were intronic variants. Three variants had a MAF of < 0.01 (c.251C > T, p.Pro86Leu; 15C > G, p.S5S; and c. 91 A > G, p.Lys31Glu). A missense variant, p.Pro86Leu, C > T, TT genotype, was found in 9 out of 200 individuals with an allele frequency of 0.045 and showed a significant association with COVID-19 (P = 0.003). The heterozygous allele of 15C > G, p.S5S, was found with a frequency of 0.02 (8/400) in eight patients, and its CG genotype showed a significant association with COVID-19 (P = 0.0068). The remaining identified variants were not associated with COVID-19 susceptibility. Conclusion: The ACE2 gene sequence in Pakistani individuals exhibited a low frequency of identified variants in COVID-19 patients. Overall, only two variants were associated with susceptibility to the disease, possibly contributing to Pakistan's lower COVID-19 mortality and infection rates. However, individuals carrying the mutant variant experienced more severe symptoms.

Foetal outcome in patients with meconium stained liquor.

OBJECTIVE: To determine the foetal outcome and mode of delivery in patients with meconium stained liquor during labour. METHODS: The observational study was carried out at the Obstetrics and Gynaecology Unit-II of Liaquat University of Medical Health Sciences from June to November 2007. The patients with gestational age more than 37 weeks who presented with meconium stained liquor and cephalic presentation were included and the foetal outcome and mode of delivery was assessed in all such subjects. The data was collected on pre-designed proforma and analysed using SPSS version 10. Chi square test was applied with 95% confidence interval and p-value < or = 0.05 was considered significant. RESULTS: A total of 75 patients with meconium stained liquor were identified during the study period. The patients with reactive cardiotocography (CTG) were 50 (66.7%) and with non-reactive CTG, 25 (33.36%). Of the total, 45 (60%) patients were delivered through normal vaginal delivery, while 30 (40%) were delivered by caesarean section. The rate of instrumental delivery was also increased which was 12 (26.7%). Among the neonates exposed to meconium stained liquor, 62 (82.7%) babies were delivered with apgar score > 7. Only 13 (17.3%) babies were delivered with apgar score < 7 in one minute. CONCLUSION: Meconium stained amniotic fluid is a common occurrence during labour and is associated with increased caesarean section rate and foetal morbidity and mortality.

Precipitating factors of hepatic encephalopathy at a tertiary care hospital Jamshoro, Hyderabad.

OBJECTIVE: To determine the precipitating factors of hepatic encephalopathy (HE) in patients with liver cirrhosis at Liaquat University Hospital Hyderabad/Jamshoro. METHODS: This hospital based descriptive study was conducted from April 2007 to September 2007. All the patients who were more than 12 years of age and were diagnosed as hepatic encephalopathy were studied. During this period, 87 patients of hepatic encephalopathy were admitted. All patients were carefully examined, relevant investigations were performed and data was collected through pre-designed proforma. RESULTS: Male patients were 65 (75%), above 40 years of age 58 (67%), belonging to interior/periphery of Sindh 54 (62%), in grade IV of hepatic encephalopathy 70 (80%) and Anti-HCV positive were 52 (60%). The most common precipitating factors detected were infection 58 (67%), constipation 43 (49%) and gastrointestinal bleeding 39 (45%). Out of 87 patients, 68 had increased total leucocytes count, 09 patients had hypokalaemia, 24 patients, hyponatraemia, 64 hypoalbuminaemia and 54 patients had a disturbed coagulation profile. Fifty nine patients recovered and were discharged while 20 patients expired. Majority of expired patients had Child-Pugh score 10-15 and were in grade IV of hepatic encephalopathy. CONCLUSION: The study concluded that there were different factors which play a key role in hepatic encephalopathy. In these factors, infection was the most common.

Type 2 diabetes mellitus: A risk factor for Helicobacter pylori infection: A hospital based case-control study.

OBJECTIVE: To determine the frequency of Helicobacter pylori (H. pylori) infection in diabetic and non-diabetic patients and to compare the frequency of H. pylori infection in both groups. STUDY DESIGN: Case control. PLACE AND DURATION: Department of Medicine, Liaquat University Hospital from October 2007 to March 2008. MATERIALS AND METHODS: This hospital-based case-control study was conducted on 148 subjects and divided into two groups i.e. type 2 diabetics and non-diabetics; each group consisting of 74 patients. All diabetic patients of >/= 35 years of age, both gender and the known cases with history of dyspepsia, epigastric pain or bloating for more than a month were screened for Helicobacter pylori infection. The collected data of both groups was evaluated and separated for analysis. RESULTS: Majority of the patients were male with mean age +/- SD, 52.86 +/- 8.51. Among the diabetic group, HpSA was positive in 54/74 (73%), whereas in the non-diabetic group HpSA was positive in 38/74 (51.4%) cases. Fasting blood glucose was identified as low in 04 (5.40%) H. pylori infected - diabetic patients where as the blood glucose level of 07 (9.45%) known diabetic patients was raised despite the ongoing medication. CONCLUSION: Diabetic patients are more prone and at risk to acquire H. Pylori infection. Therefore proper monitoring of blood glucose level and screening for H. pylori infection are effective preventive measures for this life threatening infection.
