Incidence and epidemiology of onychomycosis in patients visiting a tertiary care hospital in India.

Onychomycosis is a chronic fungal infection of the nails that is largely underdiagnosed in developing countries such as India due to poor health care facilities. In this study, we evaluated the nails of 134 patients with a clinical suspicion of onychomycosis using direct microscopy and fungal culture techniques. The majority of participants (47.8%) were older than 40 years. On both direct microscopy and fungal culture, 71.6% of participants were confirmed with onychomycosis. Among the cases confirmed by laboratory testing, distal lateral subungual onychomycosis was the most common clinical pattern observed, followed by proximal subungual onychomycosis (PSO), candidal onychomycosis (CO), and white superficial onychomycosis (WSO). We concluded that laboratory examination is of great importance in the diagnosis and identification of the underlying pathogen in patients with onychomycosis as well as in the selection of a suitable antifungal agent for treatment.

Assessing the Impact of Training on Healthcare Providers' Adherence to Infection Control Measures in Hemodialysis Services.

Background and objective Developing and implementing nursing interventions to educate nurses on infection control procedures in hemodialysis units is of utmost importance and offers significant benefits in enhancing the quality of care. This study aimed to assess the impact of training on nursing professionals' practices of hospital infection control measures in hemodialysis services. The research also intended to explore the potential association between these practices and various sociodemographic variables. Materials and methods This was a single-group, pre- and post-interventional study carried out in Haryana State, India. A pretested questionnaire consisting of 29 statements, the responses of which were measured on a 5-point Likert scale, was used as the study tool. Descriptive and statistical tests like paired-t-test were used to analyze the data. Results The practices section of the questionnaire comprised 29 statements, the responses to which were measured on a five-point Likert scale. The scoring ranged from 5 ("strongly agree", i.e., positive practice) to 1 ("strongly disagree", i.e., negative practice). The maximum achievable score was 145 and the minimum achievable score was 9. The pre-test group (i.e., before training intervention) had a mean practice score of 115.0945 [standard deviation (SD)=9.34, standard error of the mean (SE)=0.66]. However, the post-test group (i.e. after training intervention) had a mean score of 135.26 (SD=8.34, SE=0.59). The study found that structured training significantly increased the mean practice score (t=-33.70, p=0.001). In addition, the study also highlighted the significant association of mean practice scores with various demographic variables among the pre-test and post-test groups. The improvement in mean practice scores among the post-test group after the structured training program reveals that such interventions will ultimately lead to a decrease in central line-associated bloodstream infections (CLABSIs) among hemodialysis patients. Conclusions Our findings showed that the educational intervention led to significant improvements in the practices of the participants.

To assess the impact of training about hospital infection control measures related to hemodialysis services on the knowledge of healthcare providers (HCPs) at the teaching institution of Haryana.

Background: Adequate knowledge among nursing professionals toward hospital infection control measures related to hemodialysis (HD) services is essential to decrease infection among patients. Objective: This study assessed nursing professionals' knowledge about hospital infection control measures related to HD services and the effect of training interventions. Settings and Designs: It was a single group, a pre-post-interventional study conducted on nursing professionals of a single apex medical college of Haryana. Materials and Methods: A pretested questionnaire consisting of two parts was used as a study tool. Statistical Analysis: Various statistical tests such as paired t-test and Pearson's correlation were used. Results: The pre-intervention group had a lower mean knowledge score (mean knowledge = 90.2786, strongly disagree [SD] = 15.52682, standard error [SE] = 1.09518) and then the post-intervention mean knowledge score (mean knowledge = 137.5622, SD = 9.72252, SE = 0.68577). Conclusions: The training program or educational intervention proved very useful for enhancing nursing professional's knowledge about hospital infection control measures related to HD services.

Coronavirus disease (COVID-19)-associated mucormycosis (CAM): The unholy triad of COVID-19, diabetes mellitus, and corticosteroid therapy.

The whole world has battled with multiple waves of coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 virus. However, the second wave of COVID-19 had caused a worldwide havoc in terms of disease transmissibility, severity, and mortality. India has been among the worst hit countries during the second wave, which substantially overburdened and overwhelmed the Indian health care system. While secondary infections and co-infections among COVID-19 patients were increasingly being reported, COVID-19-associated mucormycosis (CAM) emerged as a new challenge particularly from India and became a matter of immediate concern. The most common causes attributed to the rise of CAM were undiagnosed/uncontrolled diabetes mellitus, excessive use of corticosteroids, and prolonged hospital stay, all of which create a perfect environment for mucormycosis infection to set in.

Perceived Stress, Knowledge, and Preventive Behaviors in Indian versus US-based Participants During COVID-19: A Survey Study.

Rationale: India and the USA, the worst affected countries by COVID-19, experienced very different pandemic courses. By 2020, COVID-19 cases had steadily declined in India, whereas the fight continued in the US. The people of India and the USA perhaps perceived threats very differently, influenced by their knowledge, available healthcare facilities, and social security. We conducted an online survey study to compare COVID-related perceptions between Indian participants (IND-P) and US-based participants (US-P). Methods: COVID-related perceptions such as stress, knowledge, and preventive behaviors were measured with specific questionnaires, and normalized scores were computed. T-tests were used to compare the perception scores, while the Kruskal-Wallis-H (KWH) tests were used to compare socioeconomic distributions between participants from two countries. Generalized linear model (GLM) adjusted for sociodemographic confounders estimated the association between the country of residence and COVID-perception. Results: The IND-P (N = 242) were younger and male-dominated compared with the US-P (N = 531) (age: KWH = 97.37, p < 0.0001, gender: KWH = 140.38, p < 0.0001). Positive attitudes toward preventive guidelines were associated with higher perceived risk and stress (r = 0.35, p < 0.001, and r = 0.21, p < 0.001, respectively) but not with the knowledge (r = -0.05, p = 0.14). Compared with the US-P, the IND-P had lower knowledge (5.19 ± 1.95 vs. 7.82 ± 1.35; t-test: p < 0.0001), higher stress (7.01 ± 1.51 vs. 6.07 ± 1.61; t-test: p < 0.0001), and better adherence to preventive guidelines (8.84 ± 1.30 vs. 8.34 ± 2.09; t-test: p = 0.0006). GLM demonstrated a significant association between the country and COVID-perception scores. Conclusion: The IND-P experienced higher stress and perceived threat during COVID-19 than the US-P, perhaps due to a lack of faith in the healthcare system and insecurity. Despite lower knowledge, the IND-P had better acceptance of preventive guidelines than the US-P.

COVID-19: The vaccination drive in India and the Peltzman effect.

The ongoing COVID-19 vaccine drives across the world, including India, may have caused people to adopt risky behavior such as decreased or non-adherence to COVID-appropriate social behavior. Such phenomenon in which people are more likely to engage in risky behavior when security measures have been mandated is termed as the "Peltzman Effect" and apart from the emergence of various variants, it may have contributed to the recent upsurge in the number of new COVID-19 cases across the world, including in India. To make the worldwide COVID-19 vaccine drive successful, it is important to acknowledge, understand and minimize the potential harms from Peltzman Effect.

Medical certification of cause of death during COVID-19 pandemic - a challenging scenario.

Death certificate data is used to monitor local, regional and national mortality trend and is helpful in improving public health as well as public safety. Accurate and reliable information about the cause of death in a population is useful for understanding disease burden estimation and trends in the health of populations; moreover, the information provided by such data is vital in terms of public health planning as well. With the continuous upsurge in mortality due to coronavirus disease 19 (COVID-19), mortality analysis could be valuable in addressing the current pandemic and implementing the epidemic control strategies effectively and efficiently. Given that COVID-19 death certification substantially affects the local and national responses towards disease prevention and transmission, the importance of the accuracy and quality of information in these certificates cannot be understated. Hence, accurate death certification related to COVID-19 is vital to understand the extent and progression of the current pandemic.

Staphylococcus aureus including MRSA nasal carriage among hospital exposed and unexposed medical students.

INTRODUCTION: Staphylococcus aureus is one of the most common human pathogen causing a wide range of infections. It is estimated that S.aureus colonizes the anterior nares in approximately 31% of the general population at any given time. The incidence of community acquired & hospital acquired S. aureus has been increasing over the past few decades, predominantly due to continuous upsurge in the drug resistant isolates. Moreover, globally the incidence of methicillin resistant S.aureus (MRSA) is progressively increasing. Hence, it would be imperative to screen all healthcare workers, interns and admitted patients for MRSA carriage and to treat all those who are found positive for the same. With the above background, the current study was undertaken to investigate the carrier rate of S. aureus (including MRSA) among hospital unexposed & exposed medical students. METHODS: A total of 181 medical students of Veer Chandra Singh Garhwali Government Institute of Medical Sciences & Research, Srinagar Garhwal, Uttarakhand. Study participants were broadly divided into two groups: hospital exposed group (n=107) and hospital unexposed group (n=74). Nasal swabs were obtained & cultured for the detection of S. aureus. Congo red agar and 0.1% Crystal Violet Assay were performed to observe the ability to form in vitro biofilm by S. aureus. RESULTS: Out of total 181 medical students 29.28% were found to be healthy carrier of S. aureus. Among the hospital exposed group 37.38% and among hospital unexposed group 17.57% were found to be healthy carrier of S. aureus. Only one student (hospital exposed group) was found to be positive for MRSA. Beta-lactamase production was noted in 90.57% strains of S. aureus while the significant rate of slime layer production was observed in 73.58% of strains. CONCLUSION: Prevalence of S. aureus nasal carriage increases with the duration of exposure to the hospital environment. The nasal carriage of S. aureus in medical students indicate the potential danger of dissemination of S. aureus including MRSA from them to the hospitalized patients which in turn complicates the treatment of same.

Impact factor: Mutation, manipulation, and distortion.

Currently, there is an increased dependency on the impact factor in scientific research publications. Sometimes the overzealousness in implementing the impact factor value to a publication is detrimental to the growth of the scientific authors, especially the junior lot, for no fault of theirs. The inept and myopic application of the impact factor defeats the purpose of making the value judgment and hence has been criticized by many learned authors. The scientist Eugene Garfield, who formulated the impact factor, feels wrong that it is being not judiciously used. A corollary is the invention dynamite by Alfred Nobel which instead of helping, aiding, and reducing human effort and endeavor it was more misused for human annihilation and pained the scientist who gave it to the world. The authors reexamine the application of impact factor to scientific manuscripts for rightful application of the value judgment.

Staphylococcus aureus: A predominant cause of surgical site infections in a rural healthcare setup of Uttarakhand.

INTRODUCTION: Surgical site infections (SSIs) represent the second most common type of healthcare-associated infections and remain a relatively common postoperative complication and the most common reason for readmission after surgery. SSIs have dire implications for the surgeon, patient, and institution which often require prolonged treatment, impose an economic burden and double the risk of patient mortality. Staphylococcus aureus is currently the most common cause of SSIs causing as many as 37% of cases of SSIs in community hospitals with methicillin-resistant S. aureus (MRSA) of particular concern. MATERIALS AND METHODS: This cross-sectional study was conducted from January 2014 to December 2014 in a rural tertiary care hospital of Pauri Garhwal district of Uttarakhand state, India. Samples were collected using sterile cotton swabs from 269 patients clinically diagnosed with SSIs and were processed as per standard microbiological techniques. Antimicrobial susceptibility testing was done using a modified Kirby-Bauer disc diffusion method. RESULTS: Out of 1294 patients, 269 (20.8%) were found to have SSIs and samples were collected from them. Out of a total of 269 samples, 258 (95.9%) yielded bacterial growth and 267 bacterial isolates were obtained. S. aureus (45.3%) was the commonest organism followed by Escherichia coli (13.9%), Pseudomonas aeruginosa (6.7%), and Proteus species (4.9%). Antimicrobial profile of S. aureus revealed maximum sensitivity to rifampicin, linezolid, teicoplanin, vancomycin, and amikacin whereas ampicillin, cefazolin, and gentamicin were found to be least sensitive. CONCLUSION: S. aureus played a predominant role in the etiology of SSIs in this hospital with MRSA being a major concern as the treatment options for such resistant strains are limited. Reduction in SSI rates can lead to both better clinical outcomes for patients and cost savings for hospitals. Adherence to strict infection control measures, maintenance of proper hand hygiene and optimal preoperative, intraoperative, and postoperative patient care can surely reduce the incidence of SSIs. A multifaceted approach involving the surgical team, microbiologist, and the infection control team is required to provide quality surgical services.

Keratomycosis due to Purpureocillium lilacinum: A case report from Sub-Himalayan region of Uttarakhand.

The fungus Purpureocillium lilacinum previously known as Paceliomyces lilacinus is an emerging pathogen that can cause severe human infections including devastating oculomycosis. Treatment with traditional antifungals often fails, and the organism shows variable susceptibility to novel triazoles. We hereby report a case of keratomycosis caused by Pur. lilacinum in an immunocompetent male patient following trauma. The patient was successfully treated with voriconazole. The drug shows good activity against Pur. lilacinum and could be a promising therapeutic alternative to treat infections caused by this fungus, which generally shows resistance to conventional antifungal agents including novel triazoles.

The Association Between Female Smoking and Childhood Asthma Prevalence-A Study Based on Aggregative Data.

Aims: Socioeconomic and environmental factors influence childhood asthma prevalence across the world. In-depth epidemiological research is necessary to determine the association between asthma prevalence and socio-environmental conditions, and to develop public health strategies to protect the asthmatic children against the environmental precipitators. Our research was based on aggregative data and sought to compare the asthma prevalence between children of two different age-groups across the world and to identify the association among the key socio-environmental conditions with increased childhood asthma prevalence. Method: We included forty countries with available data on various socio-environmental conditions (2014-2015). Childhood asthma prevalence of two different age groups (6-7 and 13-14 years) were obtained from global asthma report 2014. Because of significant diversities, the selected countries were divided into two groups based on human developmental index (HDI), a well-recognized parameter to estimate the overall socioeconomic status of a country. Robust linear regression was conducted using childhood asthma prevalence as the dependent variable and female smoking prevalence, tertiary school enrollment (TSE), PM10 (particulate matter ≤10 µm in diameter) and gross domestic product (GDP) as predictors. Results: Asthma prevalence was not different between two age groups. Among all predictors, only female smoking prevalence (reflecting maternal smoking) was associated with asthma prevalence in the countries with lower socio-economic conditions (HDI), but not in the higher HDI group. The results were unchanged even after randomization. Conclusions: Childhood asthma prevalence did not change significantly with age. Female smoking may have a positive correlation with childhood asthma prevalence in lower HDI countries.

Bacteriological Profile of Surgical Site Infections and Their Antibiogram: A Study From Resource Constrained Rural Setting of Uttarakhand State, India.

INTRODUCTION: Surgical site infections (SSI) constitute a major public health problem worldwide and are the second most frequently reported nosocomial infections. They are responsible for increasing the treatment cost, length of hospital stay and significant morbidity and mortality. AIM: To determine the incidence of SSIs and the prevalence of aerobic bacterial pathogens involved with their antibiogram. MATERIALS AND METHODS: Samples were collected using sterile cotton swabs from 137 patients clinically diagnosed of having SSIs and were processed as per standard microbiological techniques. Antimicrobial susceptibility testing was done using modified Kirby-Bauer disc diffusion method. This cross sectional study was conducted for a period of six months (January 2013 to June 2013) in the Department of Microbiology at a rural tertiary care hospital of Uttarakhand state, India. RESULTS: Out of 768 patients, 137 (17.8%) were found to have SSIs and samples were collected from them. Out of total 137 samples, 132 (96.4%) yielded bacterial growth and 139 bacterial isolates were obtained. Staphylococcus aureus (50.4%) was the commonest organism followed by Escherichia coli (23.02%), Pseudomonas aeruginosa (7.9%) and Citrobacter species (7.9%). Antimicrobial profile of gram positive isolates revealed maximum sensitivity to vancomycin, teicoplanin and linezolid, whereas among gram negative isolates meropenem, piperacillin-tazobactam, and amikacin were found to be most sensitive. CONCLUSION: The rate of SSI observed in this study was comparable to other similar studies, however we observed a higher degree of antimicrobial resistance. Adherence to strict infection control measures, maintenance of proper hand hygiene and optimal preoperative, intraoperative and postoperative patient care will surely reduce the incidence of SSIs.

Mobile phones: Reservoirs for the transmission of nosocomial pathogens.

BACKGROUND: Global burden of hospital-associated infection (HAI) is on the rise and contributes significantly to morbidity and mortality of the patients. Mobile phones are indispensible part of communication among doctors and other health care workers (HCWs) in hospitals. Hands of HCWs play an important role in transmission of HAI and mobile phones which are seldom cleaned and often touched during or after the examination of patients without hand washing can act as a reservoir for transmission of potent pathogens. This study aimed to investigate the rate of bacterial contamination of mobile phones among HCWs in our tertiary care hospital and to compare it with personal mobile phones of non-HCWs (control group). MATERIALS AND METHODS: The mobile phones and dominant hands of 386 participants were sampled from four different groups, hospital doctors and staff (132), college faculty and staff (54), medical students (100) and control group (100). Informed consent and questionnaire was duly signed by all the participants. Samples were processed according to standard guidelines. RESULTS: 316 mobile phones (81.8%) and 309 hand swab samples (80%) showed growth of bacterial pathogens. The most predominant isolates were Coagulase-negative Staphylococcus, Staphylococcus aureus, Acinetobacter species, Escherichia coli, Klebsiella pneumoniae, Pseudomonas species and Enterococcus species. CONCLUSION: Hundred percent contamination was found in mobile phones and hands of HCWs indicating mobile phones can be the potential source of nosocomial pathogens. Our study results suggest that use of mobile phones in health care setup should be restricted only for emergency calls. Strict adherence to infection control policies such as proper hand hygiene practices should be followed.

The prevalence of inducible clindamycin resistance among staphylococci in a tertiary care hospital - a study from the garhwal hills of uttarakhand, India.

OBJECTIVE: This study was undertaken to assess the frequency of the phenotypic expression of the inducible resistance to clindamycin which was due to the expression of the erm genes in various clinical isolates of the Staphylococcus species. MATERIALS AND METHODS: This was a cross sectional study conducted in the Dept. of Microbiology and Immunology, Veer Chandra Singh Garhwali Govt. Medical Sciences and Research Institute, Srikot, Uttarakhand, from July 2010 to December 2011. A total of 373 consecutive, non duplicate strains of Staphylococci isolated from various clinical samples like pus, wound swab, blood, urine and other body fluids, were tested. The isolates which had a discordant resistance pattern (clindamycin-sensitive and erythromycin-resistant) by Kirby Bauer Disk Diffusion method were selected and subjected to the D-test for inducible clindamycin resistance, as per the Clinical and Laboratory Standards Institutes (CLSI) guidelines. RESULTS: Among the 373 clinical isolates of Staphylococci which were studied, 134 isolates showed a discordant resistance pattern. Among these discordant strains, 45 (33.6%) isolates were D-test positive, which had inducible clindamycin resistance and belonged to the inducible macrolide lincosamide streptogramin- B phenotype (MLSBi). 89 (66.4%) isolates were D-test negative and they belonged to the macrolide streptogramin phenotype (MS). Among the MLSBi phenotypes, 6 (13.3%) isolates were methicillin-resistant Staphylococcus aureus (MRSA), 13 (28.9%) were Methicillin-sensitive S.aureus (MSSA) and 26 (57.8%) were coagulase negative staphylococci (CONS). CONCLUSION: The D-test is a simple, effective and an important method for the phenotypic detection of inducible clindamycin resistance and it should be used routinely, as it will help in guiding the empirical therapy. The possible clinical failures can thus be avoided.

The baseline widal titre among the healthy individuals of the hilly areas in the garhwal region of uttarakhand, India.

INTRODUCTION: Typhoid fever is endemic in all parts of India and the Widal test is widely used for its diagnosis. In the endemic areas, the healthy people may contain antibodies which are capable of reacting upto a variable titre in the Widal test, due to a past exposure, TAB vaccination and cross reacting antigens. Therefore it varies widely from place to place and is referred to as the baseline titre of that area. The aim of this study was to determine the average baseline titre of the apparently healthy population in the Garhwal region of Uttarakhand, India. MATERIAL AND METHODS: Blood samples were collected from healthy volunteers over the period from February 2011 to January 2012 and they were analyzed for the presence of the Salmonella antibodies by carrying out the Widal tube agglutination test. RESULTS: Among the 2164 serum specimens which were tested, 922 (42.6%) sera were found to be positive for the Widal test and 1242 were negative. The most frequently recorded titre of the reactive sera was 1:40 for the anti-O antibodies and it was 1:80 for the anti-H antibodies and this was the baseline titre for this region. CONCLUSION: Based on the above results of our study, it has been recommended that the cut-off titre of 1:80 for the anti-O antibodies and of 1:160 for the anti-H antibodies may be considered as diagnostic for enteric fever in the Garhwal region of Uttarakhand, India.

Microbiology of chronic suppurative otitis media in a tertiary care setup of uttarakhand state, India.

BACKGROUND: Chronic suppurative otitis media (CSOM) is a notorious infection and a major health problem in developing countries causing serious local damage and threatening complications. Early and effective treatment based on the knowledge of causative micro-organisms and their antimicrobial sensitivity ensures prompt clinical recovery and possible complications can thus be avoided. AIMS: The aim of this study was to isolate the organisms associated with CSOM and to detect the antibiogram of the aerobic isolates. MATERIALS AND METHODS: A total of 204 patients clinically diagnosed of CSOM were enrolled in the study and the samples were obtained from each patient using sterile cotton swabs and cultured for microbial flora. Drug susceptibility testing for aerobic isolates was conducted using Kirby-Bauer disc diffusion method. RESULTS: The most common causative organisms isolated were Staphylococcus aureus (48.69%) and Pseudomonas aeruginosa (19.89%) amongst the 191 aerobic isolates. Anaerobes accounted for 29.41% of the isolates while 12.25% were fungi. Antimicrobial profile of aerobic isolates revealed maximum sensitivity to amikacin (95.5%), ceftriaxone (83.4%) and gentamicin (82.7%). CONCLUSION: Knowing the etiological agents of CSOM and their antimicrobial susceptibility is of essential importance for an efficient treatment, prevention of both complications and development of antibiotic resistance and finally, the reduction of the treatment costs.
