An evolutionary perspective on human female sexual desire

The maternal mortality rate in the Third World remains high despite the launch of the Safe Motherhood Initiative (SMI) in 1987. There are various sociocultural, political and economic factors which play a major role in this. The five main causes of maternal mortality are haemorrhage, sepsis, unsafe abortion, hypertensive disorders and obstructed labour. The key to safe motherhood lies in providing quality maternity care for all women. It is important to know the nature and the extent of the problems in the community so that appropriate technology can be introduced with optimum utilization of the available resources. The different ways of achieving safe motherhood are discussed with emphasis on community based interventions. The SMI goals can be reached provided the Safe Motherhood programmes are well funded, the community workers well trained and the leaders of the community and the nation dedicated.     

Efficacy of Subgingivally Delivered Simvastatin in the Treatment of Patients With Type 2 Diabetes and Chronic Periodontitis: A Randomized Double‐Masked Controlled Clinical Trial

Background: Simvastatin (SMV) is a specific competitive inhibitor of 3‐hydroxy‐2‐methyl‐glutaryl coenzyme A reductase. Recently, it has been reported that statins promote bone formation. The present study is designed to investigate the effectiveness of 1.2% SMV in an indigenously prepared, biodegradable, controlled‐release gel as an adjunct to scaling and root planing (SRP) in the treatment of patients with type 2 diabetes and chronic periodontitis (CP). Methods: Thirty‐eight patients were categorized into two treatment groups: SRP plus 1.2% SMV and SRP plus placebo. Clinical parameters were recorded at baseline before SRP and at 3, 6, and 9 months; they included modified sulcus bleeding index (mSBI), probing depth (PD), and clinical attachment level (CAL). At baseline and after 6 and 9 months, radiologic assessment of intrabony defect (IBD) fill was done using computer‐aided software. Results: Mean PD reduction and mean CAL gain were found to be greater in the SMV group than the placebo group at 3, 6, and 9 months. Furthermore, significantly greater mean percentage of bone fill was found in the SMV group (32.64% ± 12.90%) compared to the placebo group (4.22% ± 9.75%) after 9 months. Conclusion: There was a greater decrease in mSBI and PD and more CAL gain with significant IBD fill at sites treated with SRP plus locally delivered SMV in patients with type 2 diabetes and CP.     

Study of PTPN22 1858C/T polymorphism in rheumatoid arthritis patients from Western India

BackgroundRheumatoid arthritis (RA) is an inflammatory autoimmune disorder with etiologies including genetic and environmental factors. Protein tyrosine phosphatase non-receptor type22 (PTPN22) 1858C/T polymorphism is widely suspected to be a susceptibility gene for RA in the non-HLA genes group.AimThis study aimed at determining whether PTPN22 1858C/T polymorphism is associated with RA patients from Western India and to evaluate its possible association with rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) autoantibodies.MethodsA total of 130 Indian RA patients and 100 age and sex matched normal controls were genotyped by polymerase chain reaction restriction fragment length polymorphism (PCR–RFLP) for the PTPN22 1858C/T polymorphism.ResultsRF positivity was seen among 73.8% RA patients studied and the overall incidence of anti-CCP antibodies was 86.2%. The homozygous genotype (T/T) was absent in both groups. Among RF positives, C/C homozygosity was 90.6% whereas 9.4% patients were C/T heterozygous. Among anti-CCP positives, 89.1% had C/C genotype while the remaining 10.9% have the C/T genotype. Statistically significant association was obtained between the polymorphism and anti-CCP positivity in RA patients (OR: 2.939, ‘p’ value = 0.0595).ConclusionOur study suggested that a positive autoantibody status may predispose an individual to RA. PTPN22 may act as a susceptibility gene only in certain ethnic groups and there is no direct association between PTPN22 C1858 polymorphism and RA patients from Western India. Still a larger study is needed to understand whether this polymorphism predisposes individual to disease-associated antibodies among Indian RA patients.     

A virtual COVID-19 ophthalmology rotation

The coronavirus (COVID-19) pandemic temporarily suspended medical student involvement in clinical rotations, resulting in the need to develop virtual clinical experiences. The cancellation of clinical ophthalmology electives and away rotations reduces opportunities for exposure to the field, to network with faculty, conduct research, and prepare for residency applications. We review the literature and discuss the impact and consequences of COVID-19 on undergraduate medical education with an emphasis on ophthalmic undergraduate medical education. We also discuss innovative learning modalities used from medical schools around the world during the COVID-19 pandemic such as virtual didactics, online cases, and telehealth. Finally, we describe a novel, virtual neuro-ophthalmology elective created to educate medical students on neuro-ophthalmology foundational principles, provide research and presentation opportunities, and build relationships with faculty members. These innovative approaches represent a step forward in further improving medical education in ophthalmology during COVID-19 pandemic and beyond.     

Impact of COVID-19 on Indian optometrists: A student,educator, and practitioner‘s perspective

Purpose:The optometry profession has experienced massive changes amid lockdown in COVID 19 pandemic. This study gauges the impact of COVID-19 on optometry education and practices in India.Methods:The impact of COVID-19 among key stakeholders of Indian optometry that included educators, students, and practitioners was surveyed. The content validity of the survey tool was achieved through a focused group discussion with experts.Results:Of the 1408 responses, 118 were educators, 845 were students and 445 were practitioners. Post COVID-19 lock-down, a high percentage of students (96%) and educators (94%) were now using online mode of education to learn and teach. The blended learning methods were reported to be used by 81% of educators. Practical skills were the most difficult to teach by educators and to learn by students. Almost a third of the students were concerned about their internships and job opportunities amid the pandemic. Practitioners felt confident in performing routine eye examinations with personal protective equipment (PPE). Telemedicine was found to be adopted by 55% of the private practitioners and 49% of the eye hospitals.Conclusion:The COVID-19 pandemic has provided an opportunity to reform Indian optometry education through blended learning methods. Optometry practices changed and adapted instantly to the new hygiene norms that have raised the standard of care provided to patients. Telemedicine emerged as a mode of providing care by optometrists. Overall, all key stakeholders of optometry in India were found to have adapted well to the sudden changes due to COVID 19 pandemic.     

Detection of New Delhi Metallo‐beta‐Lactamase and Extended‐Spectrum beta‐Lactamase Genes in Escherichia coli Isolated from Mastitic Milk Samples

In this study, eight Escherichia coli isolates were obtained from milk samples of dairy cattle suffering from clinical/subclinical mastitis. Isolates were characterized for antimicrobial resistance traits and virulence genes. Results revealed that one isolate was harbouring New Delhi metallo‐beta‐lactamase gene (bla_NDM). Cloning and sequencing of the PCR amplicon confirmed the identity of the gene (GenBank accession no. KC769583 ) having 100% homology with bla_NDM‐5 (GenBank accession no. JN104597.1 ), and this isolate was susceptible to colistin, chloramphenicol and tetracycline only. Moreover, another isolate carried extended‐spectrum beta‐lactamase (ESBL) gene – bla_CTX‐M, and all isolates possessed bla_TEM gene. Of the eight isolates, only one isolate was positive for shiga toxin gene (stx2), and none were harbouring stx1 gene. Occurrence of New Delhi metallo‐beta‐lactamase (bla_NDM) in one E. coli isolate and ESBL genes in other isolates poses a potential threat to human health following possible entry and spread through food chain.
