Since the 1960’s, meticillin-resistant Staphylococcus aureus (MRSA) has become a major pathogen with ever-increasing incidence rates of hospital-acquired and community-acquired infections. Malta has currently one of the highest rates of hospital-acquired and community-acquired infections in Europe. In addition, reports have estimated community carriage at more than 8%. MRSA carriage in homes for the elderly is very important because these residents are often hospitalized and therefore serve as a source of transmission. The aims of this study were to establish the prevalence of MRSA nasal carriage amongst residents in nursing homes in Malta, to determine their antibiotic susceptibility and to determine the significance of specific risk factors found in the literature. Nasal swabs were taken from 397 randomly chosen residents in 10 governmental nursing homes. A short questionnaire including possible risk factors reported to be associated with MRSA nasal carriage was also filled. MRSA carriage amongst nursing home residents was 19.4% (95% CI 17.6 – 21.2%) ranging from 0% to 25% amongst the nursing homes studied. Logistic regression analyses indicated that previous hospital admission was the only risk factor that was found to be significantly (OR: 1.956, p: 0.011; 95CI 1.163 - 3.290) associated with MRSA nasal colonization amongst nursing home residents. A high carriage rate of MRSA was identified in Maltese nursing care residents which can contribute to maintaining MRSA incidence in hospitals. Possible interventions include screening of these patients when they are admitted to an acute care facility and possible decolonization attempts in the nursing homes.

Objectives:To determine the prevalence of and the risk factors for methicillin-resistant Staphylococcus aureus (MRSA) carriage in nursing home residents in the Rhine-Neckar region of southern Germany.Design:Point-prevalence survey.Setting:Forty-seven nursing homes in the region.Participants:All residents of the approached nursing homes who agreed to participate.Methods:After informed consent was obtained, all participants had their nares swabbed, some personal data collected, or both. All swabs were examined for growth of MRSA All S. aureus isolates underwent oxacillin susceptibility testing and polymerase chain reaction for demonstration of the meek gene. All MRSA isolates were typed using pulsed-field gel electrophoresis after digestion with SmaI.Results:Swabs from 3,236 nursing home residents yielded 36 MRSA strains, contributing to a prevalence rate of 1.1%. Significant risk factors for MRSA carriage in the multivariate analysis were the presence of wounds or urinary catheters, limited mobility, admission to a hospital during the preceding 3 months, or stay in a medium-size nursing home. One predominant MRSA strain could be detected in 30 of the 36 MRSA carriers.Conclusions:The prevalence of MRSA in German nursing homes is still low. These residents seemed to acquire their MRSA in the hospital and transfer it to their nursing home. Apart from well-known risk factors for the acquisition of MRSA we identified the size of the nursing home as an independent risk factor. This might be due to an increased use of antimicrobials in nursing homes of a certain size.

  Objective: The incidence of community-acquired and hospital-acquired Staphylococcus aureus infections has been rising with increasing emergence of drug-resistant strains called methicillin-resistant S. aureus (MRSA). The main objective of this study was to determine the prevalence of carriage rate of MRSA among the interns of tertiary care teaching hospital in Mangalore.Methods: A total of 150 interns were participated, thereby swabs from both anterior nares were collected and processed for S. aureus. The isolated strains of S. aureus were screened for methicillin susceptibility by modified Kirby–Bauer method using cefoxitin (30 μg) disc. Further, antibiotic susceptibility testing for all isolates of S. aureus was also done against selected appropriate antibiotics. Vancomycin susceptibility testing for MRSA was done by E test.Results: The number of strains of S. aureus isolated from our 150 participants was 71 with a percentage rate of 47.3. Of the 71 isolates of S. aureus, one (1.4%) was MRSA. The overall MRSA carriage rate was 0.66%. The S. aureus and MRSA carriage rates recorded in this study were at par and significantly lower, respectively, when compared with other reported studies. It was observed that risk factors such as the use of antibiotics in the past 6 months and smoking were found to be statistically significant in nasal carriage status of S. aureus (<0.05). The only one isolate of MRSA was found to be sensitive to vancomycin, linezolid, and teicoplanin.Conclusion: It was concluded that the acquisition of S. aureus and MRSA would not be an occupational hazard for medical students of developing countries like India.

Urinary incontinence (UI) is a common problem among older adults. This study investigated the prevalence of UI in nursing home residents aged ≥75 years in China and examined potential risk factors associated with UI and its subtypes. Data were collected during face-to-face interviews using a general questionnaire, the International Consultation Incontinence Questionnaire Short-Form, and the Barthel Index. A total of 551 participants aged ≥75 years residing in Changsha city were enrolled from June to December 2018. The UI prevalence rate among nursing home residents aged ≥75 years was 24.3%. The most frequent subtype was mixed (M) UI (38.1%), followed by urge (U) UI (35.1%), stress (S) UI (11.9%), and other types (14.9%). In terms of severity, 57.5% had moderate UI, while 35.1% had mild and 7.5% had severe UI. Constipation, immobility, wheelchair use, cardiovascular disease (CVD), and pelvic or spinal surgery were significant risk factors for UI. Participants with a history of surgery had higher risks of SUI (odds ratio [OR] = 4.87, 95% confidence interval [CI]: 1.55–15.30) and UUI (OR = 1.97, 95% CI: 1.05–3.71), those who were immobile or used a wheelchair had higher rates of MUI (OR = 11.07, 95% CI: 4.19–29.28; OR = 3.36, 95% CI: 1.16–9.78) and other UI types (OR = 7.89, 95% CI: 1.99–31.30; OR = 14.90, 95% CI: 4.88–45.50), those with CVD had a higher rate of UUI (OR = 2.25, 95% CI: 1.17–4.34), and those with diabetes had a higher risk of UUI (OR = 2.250, 95% CI: 1.14–4.44). Use of oral antithrombotic agents increased UUI risk (OR = 4.98, 95% CI: 2.10–11.85) whereas sedative hypnotic drug use was associated with a higher risk of MUI (OR = 3.62, 95% CI: 1.25–10.45). Each UI subtype has distinct risk factors, and elderly residents of nursing homes with a history of CVD and pelvic or spinal surgery who experience constipation should be closely monitored. Reducing time spent in bed and engaging in active rehabilitation including walking and muscle strengthening may aid in UI prevention and treatment.

An anonymized point-prevalence survey of methicillin-resistant Staphylococcus aureus (MRSA) carriage was conducted amongst a stratified random sample of nursing home residents in Birmingham, UK, during 1994. Microbiological sampling from noses, fingers and the environment was undertaken. Information about potential risk factors for the acquisition of MRSA was gathered. MRSA was isolated from cultures of the nose or fingers of 33 of the 191 residents who took part in the study (17%) but only 1 of the 33 positive residents had a clinical infection. Although just 10 of the 87 environmental samples were MRSA positive, there was some environmental contamination in most homes. Risk factors for MRSA carriage were hospital admission within the last year (relative prevalence 2·09, 95% CI 1·13–3·88; P < 0·05) and surgical procedures within the last year (relative prevalence 4·02, 95% CI 2·18–7·43; P = 0·002). Phage-typing of the strains revealed similarities with those circulating in Birmingham hospitals. These findings suggest that the prevalence of MRSA in nursing homes in Birmingham was high, and that the strains may have originated in hospitals.

Objective. Methicillin-resistant Staphylococcus aureus (MRSA) is one of the main causative agents of nosocomial infections that has posed a major threat to those with compromised immune systems such as nursing home residents. The aim of this study was to determine the rates of MRSA strains and the types of Staphylococcal Cassette Chromosome mec (SCCmec)in nursing homes in Saudi Arabia. Methods. A total of 188 nasal swabs were collected from the residents and nursing staff in two nursing homes in Riyadh, Saudi Arabia. All MRSA isolates were tested for antimicrobial susceptibility and analyzed for mecA and SCCmec typing by multiplex PCR assay. Detection of the Panton–Valentine leukocidin (PVL) gene was also tested in all positive MRSA isolates by multiplex PCR using specific primers. Results. Among the 188 collected nasal swabs (105 males and 83 females), MRSA colonization rate was 9.04% (11 (5.85%) females and 6 (5.71%) males). About 47% of MRSA were multidrug resistant (MDR) as acquired resistance to beta-lactam, macrolide, and aminoglycoside antibiotics. However, all the MRSA isolates showed susceptibility to vancomycin, tigecycline, and linezolid. All the MRSA isolates (n = 17) were mecA-positive with the SCCmec IVc (n = 7, 41.18%) as the most common SCCmec type followed by SCCmec V (n = 5, 29.41%) and SCCmec IVa (n = 2, 11.76%). The remaining isolates (n = 3) were nontypeable (17.65%). In addition, the PVL toxin gene was only detected in four of the male samples. Conclusion. MRSA nasal colonization is a common incident among nursing home residents. The prevalence of community-associated (CA) MRSA (SCCmec IV and V) was more common than hospital-associated (HA) MRSA in our study samples. It is crucial to investigate such rate of incidence, which is a key tool in preventive medicine and would aid in determining health policy and predict emergent outbreaks.
