Impact of Bundled Intervention on Outcomes of Patients Undergoing Clean Orthopedic Surgeries With Hardware Implants: Small Prospective Randomized Controlled Trial.

Background: Prosthesis-related infections (PRIs) and surgical site infections (SSIs) remain one of the most devastating complications among patients undergoing clean orthopedic surgeries. Prevention strategies are critical to reduce infection rates in orthopedic surgeries. The current study aimed to determine the effectiveness of a set of evidence-based practices (bundled intervention) in reducing the incidence of PRIs and SSIs among patients undergoing clean orthopedic surgeries with hardware implants. Patients and Methods: A prospective, interventional randomized controlled trial was conducted for a period of three years. A total of 597 patients were enrolled, and depending on their Staphylococcus aureus carrier status were categorized into carrier group (n = 98) and non-carrier group (n = 499). Only carrier group patients were analyzed for effectiveness of bundled interventions, after being randomly assigned to two subgroups: interventional carrier group (ICG; n = 50) and non-interventional carrier group (NICG; n = 48). Results: Of the 597 patients, 98 (16.4%) were colonized with Staphylococcus aureus, among whom 9 (19.4%) had methicillin resistance. During follow-up, overall infection rate of 1.1% was observed (PRI, 0.3%; SSI, 0.8%). There was no case of PRI/SSI in the ICG. However, in the NICG, one patient developed SSI because of methicillin-resistant Staphylococcus aureus. An endogenous source of infection was demonstrated by pulsed field gel electrophoresis (PFGE). The SSI rate was higher in the NICG (p = 0.002). In the non-carrier group (n = 499), SSIs/PRIs occurred among 1.2% of the patients, because of organisms other than Staphylococcus aureus. Conclusions: Benefit of bundle intervention approach could be demonstrated. Further studies assessing the effectiveness of the individual components of the bundle can inform clinical practice greatly.

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.

Knowledge, attitude, and practices of health-care providers toward antibiotic prescribing, antibiotic resistance, and multidrug-resistant tuberculosis.

INTRODUCTION: Antibiotic resistance (ABR) is a growing public health problem and is a subject of international concern. It poses a serious threat to health and health-care systems in both developed and developing countries. The problem is more confounding with tuberculosis (TB), and drug resistance in TB has threatened the progress made in TB care and control worldwide. The aim of this study was to understand the knowledge, attitude, and practices of health-care providers (HCPs) toward antibiotics, antibiotic prescribing, ABR, and multidrug-resistant TB (MDR-TB). MATERIALS AND METHODS: A total of 125 participants were included in this cross-sectional, questionnaire-based survey conducted in tertiary care teaching hospitals of the Delhi-NCR region. A five-point Likert scale, whose responses ranged from "strongly agree" to "do not know," was used to record the responses from participants. RESULTS: Among the 125 HCPs who participated in the survey, the response rate was 100%. Around 94.4% of the respondents agreed that ABR is an important and a serious public health issue. More than 80% of the respondents strongly agreed that over-the-counter sale and/or dispensing antibiotics without prescription should be controlled. About 86.4% of the participants agreed that MDR-TB is a growing problem and 59.2% strongly agreed that indiscriminate use of anti-TB drugs could be a major causative factor. Almost 85.6% of the participants agreed that a proper diagnosis should be ensured before treating the TB cases. CONCLUSIONS: HCPs had a good knowledge of antibiotics and the association of its misuse or overuse with increasing ABR. Educational and persuasive measures are certainly needed, but the use of restrictive and organizational measures appears mandatory if the misuse of antibiotics is to be decreased in the near future. A stringent assessment of the impact of implemented measures seems essential to better guide antibiotic stewardship in our country.

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.

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.

Blood lead levels among the occupationally exposed workers and its effect on calcium and vitamin D metabolism: A case-control study.

INTRODUCTION: Lead (Pb) is one of the major occupational pollutants present in the developed and developing countries including India. In humans, Pb can cause a wide range of biological effects depending upon the level and duration of exposure. The goal of this study was to evaluate the blood lead levels (BLLs) and its associated effects on vitamin D and calcium metabolism, among the workers occupationally exposed to Pb. MATERIALS AND METHODS: This cross-sectional, case-control study was conducted for a period of 18 months (January 2017 to July 2018). A total of 160 subjects were included in the study (80 in each, Pb-exposed group and control group). The blood Pb levels were quantified by using an inductively coupled plasma mass spectrometry with triple quadrupole technology (iCAP™ TQ ICP-MS). Other biochemical parameters were estimated using fully automatic analyzer by RANDOX, RX-imola, Crumlin, UK and Johnson and Johnson, VITROS® ECiQ, Immunodiagnostic system, Ortho Clinical Diagnostics, New Jersey, USA. RESULTS: Upon analysis it was observed that serum calcium, phosphorous, and vitamin D levels were significantly decreased (8.35 ± 0.42 mg/dl, 3.07 ± 0.34 mg/dl, and 28.82 ± 10.81 ng/ml respectively; P < 0.001), whereas the BLL and serum iPTH levels were significantly increased (38.02 ± 19.92 µg/dl and 116.78 ± 19.93 pg/ml respectively; P < 0.001) in Pb exposed subjects as compared to control subjects. CONCLUSION: Our study results demonstrated that high BLL significantly alter vitamin D and calcium metabolism. The data extrapolated from our study emphasizes the necessity of surveillance in exposed workers. As the associated deleterious effects of Pb-exposure can be serious, we propose that a routine-periodical screening of the workers exposed to lead should be conducted.

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.

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.

Microbiological evaluation of clinically suspected cases of tubercular lymphadenopathy by cytology, culture, and smear microscopy - A hospital-based study from Northern India.

INTRODUCTION: Over the past few years, the incidence of extrapulmonary tuberculosis (EPTB), particularly of tubercular lymphadenitis (TBLN), is on the rise. TBLN, which contributes to 20-40% of EPTB cases, often poses a diagnostic and therapeutic challenge for clinicians more so in resource-constrained settings where laboratory confirmation is not available. In this study, we aimed to study if fine-needle aspiration cytology (FNAC) combined with Ziehl-Neelsen (ZN) staining and mycobacterial culture could improve the diagnostic accuracy in patients clinically suspected of TBLN. MATERIALS AND METHODS: This cross-sectional study involved 120 patients (>12 years of age), clinically suspected of peripheral TBLN. Direct examination of the samples with ZN staining and culture on Lowenstein-Jensen (LJ) slants and Bactec MGIT 960 vials (MGIT 960 medium) was performed on previously collected fine-needle aspirates. RESULTS: Out of total 120 patients included in study, 43.3% were males and 56.7% were females. Maximum numbers of cases were observed in age group 13-21 (56%). On ZN staining, 21.7% samples were found positive, whereas FNAC findings were suggestive of tuberculosis (TB) in 455 patients. Culture on LJ media showed 33.3% samples to be positive, whereas Bactec MGIT 960 system showed positivity of 35%. Out of 54 samples suggestive of TB on FNAC, only 30 (55.6%) were found positive on Bactec culture. Also out of 66 samples which were not suggestive of TB in FNAC, 12 (18.2%) were found positive in Bactec culture. CONCLUSION: Accurate diagnosis of TBLN requires a multifaceted approach involving microbiology, pathology, radiology, and clinical presentation of the disease. FNAC and ZN staining along with the culture can result in better diagnostic yield and will be helpful in reducing the burden of TB.

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.

Chlamydia trachomatis proctitis masquerading as carcinoma rectum: First case report from India.

While proctitis is caused both by infectious and noninfectious causes, infectious causes are acquired typically sexually. Chlamydia trachomatis, which is the most frequent bacterial pathogen causing sexually transmitted infections worldwide, is one of the causative agents of proctitis. We report a case history of a bisexual male who presented to us with rectal bleeding. The colonoscopy showed a nodular ulcerated lesion in the rectum suggestive of rectal malignancy, but biopsies from rectal mass did not reveal malignancy. A rectal biopsy was positive for C. trachomatis by polymerase chain reaction assay, and a diagnosis of C. trachomatis proctitis was made. Considering the invasive anorectal disease and patient's sexual history, he was treated with prolonged doxycycline therapy as per Centres for Disease Control and Prevention's treatment recommendation for lymphogranuloma venereum. A high index of clinical suspicion along with appropriate microbiological testing can clinch the diagnosis of C. trachomatis infection.
