Genome-wide association study and polygenic score assessment of insulin resistance
Insulin resistance (IR) and beta cell dysfunction are the major drivers of type 2 diabetes (T2D). Genome-Wide Association Studies (GWAS) on IR have been predominantly conducted in European populations, while Middle Eastern populations remain largely underrepresented. We conducted a GWAS on the indices of IR (HOMA2-IR) and beta cell function (HOMA2-%B) in 6,217 non-diabetic individuals from the Qatar Biobank (QBB; Discovery cohort; n = 2170, Replication cohort; n = 4047) with and without body mass index (BMI) adjustment. We also developed polygenic scores (PGS) for HOMA2-IR and compared their performance with a previously derived PGS for HOMA-IR (PGS003470). We replicated 11 loci that have been previously associated with HOMA-IR and 24 loci that have been associated with HOMA-%B, at nominal statistical significance. We also identified a novel locus associated with beta cell function near VEGFC gene, tagged by rs61552983 (P = 4.38 × 10-8). Moreover, our best performing PGS (Q-PGS4; Adj R2 = 0.233 ± 0.014; P = 1.55 x 10-3) performed better than PGS003470 (Adj R2 = 0.194 ± 0.014; P = 5.45 x 10-2) in predicting HOMA2-IR in our dataset. This is the first GWAS on HOMA2 and the first GWAS conducted in the Middle East focusing on IR and beta cell function. Herein, we report a novel locus in VEGFC that is implicated in beta cell dysfunction. Inclusion of under-represented populations in GWAS has potentials to provide important insights into the genetic architecture of IR and beta cell function
A Review about Internet of Things (IoT) integration with Cloud Computing with a Limelight on Security
Cloud computing has become a pivotal and widely embraced technology due to its accessibility and cost-effectiveness. This review explores the intersection of cloud computing and Internet-of-Things (IoT) devices, highlighting the remarkable advancements made in resource utilization and storage methods. However, this rapid growth has also raised concerns about security. Through an in-depth analysis of recent research, we examine the security challenges associated with IoT-based cloud computing, including account hacking, phishing, malware, middleman attacks, and service denial. We also discuss the potential benefits, architectural integration options, and the impact of IoT on cloud computing. This review paper categorizes findings and solutions from recent research papers, ultimately shedding light on the vulnerabilities and weaknesses of IoT-based cloud computing, along with its performance and stability issues
Assessment of adherence to the core elements of hospital antibiotic stewardship programs: a survey of the tertiary care hospitals in Punjab, Pakistan
Abstract: Background: To restrain antibiotic resistance, the Centers for Disease Control and Prevention
(CDC), United States of America, urges all hospital settings to implement the Core Elements
of Hospital Antibiotic Stewardship Programs (CEHASP). However, the concept of hospital-based
antibiotic stewardship programs is relatively new in Low- and Middle-Income Countries. Aim: To
appraise the adherence of the tertiary care hospitals to seven CEHASPs. Design and Setting: A crosssectional
study in the tertiary care hospitals in Punjab, Pakistan. Method: CEHASP assessment tool,
(a checklist) was used to collect data from the eligible hospitals based on purposive sampling. The
check list had 19 statements to cover seven CEHASPs: Hospital Leadership Commitment, Accountability,
Pharmacy Expertise, Action (Implement Interventions to Improve Antibiotic Use), Tracking Antibiotic Use
and Outcomes, Reporting Antibiotic Use and Outcomes, and Education. For each statement, a response of
“YES”, “NO” or “Under Process” constituted a score of 2, 0 and 1, respectively, where the higher the
scores the better the adherence. Categorical variables were described through descriptive statistics,
while independent t-test computed group differences. Result: A total of 68 hospitals (n = 33 public,
n = 35 private) participated with a response rate of 79.1%. No hospital demonstrated “Perfect”
adherence. Roughly half private (48.6%) and more than half public (54.5%) sector hospitals were
“Poor“ in adherence. Based on the mean score, there was no significant difference between the
private and the public hospitals in terms of comparison of individual core elements. The two most
neglected core elements emerged as top priority area were: Reporting Antibiotic Use and Outcomes and
Tracking Antibiotic Use and Outcomes. Conclusion: The current response of Pakistan to implement
hospital-based antibiotic stewardship programs is inadequate. This study points out significant gaps
of practice both in public and private tertiary care hospitals. A majority of the core elements of
antibiotic stewardship are either absent or ”Under Process”. The deficiency/priority areas mentioned
require immediate attention of the concerned stakeholders in Pakistan
