Microbiological Status

Venous leg ulcers are frequently colonized by microbes. This can be particularly devastating if the ulcer is infected with alert pathogens, i.e., highly virulent microorganisms with well-developed mechanisms of antibiotic resistance. We analyzed the microbiological status of venous leg ulcers and identified the clinicodemographic predictors of culture-positive ulcers, especially in ulcers with colonization by alert pathogens. Methods: This study included 754 patients with chronic venous leg ulcers. Material for microbiological analysis was collected by swabbing only from patients who did not receive any antibiotic treatment. Results: A total of 636 (84.3%) patients presented with culture-positive ulcers. Alert pathogens, primarily Pseudomonas aeruginosa, were detected in 28.6% of the positive cultures. In a logistic regression model, culture-positive ulcers were predicted independently by age > 65 years, current ulcer duration > 12 months, and ulceration area greater than 8.25 cm2. Two of these factors, duration of current ulcer > 12 months and ulceration area > 8.25 cm2, were also identified as the independent predictors of colonization by alert pathogens. Conclusions: Colonization/infection is particularly likely in older persons with chronic and/or large ulcers. Concomitant atherosclerosis was an independent predictor of culture-negative ulcers.

ObjectivesTo evaluate the performance of the predictors in estimating the probability of pulmonary tuberculosis (PTB) when all versus only significant variables are combined into a decision model (1) among all clinical suspects and (2) among smear-negative cases based on the results of culture tests.DesignA cross-sectional study.SettingTwo public referral hospitals in Tigray, Ethiopia.ParticipantsA total of 426 consecutive adult patients admitted to the hospitals with clinical suspicion of PTB were screened by sputum smear microscopy and chest radiograph (chest X-ray (CXR)) in accordance with the Ethiopian guidelines of the National Tuberculosis and Leprosy Program. Discontinuation of antituberculosis therapy in the past 3 months, unproductive cough, HIV positivity and unwillingness to give written informed consent were the basis of exclusion from the study.Primary and secondary outcome measuresA total of 354 patients were included in the final analysis, while 72 patients were excluded because culture tests were not done.ResultsThe strongest predictive variables of culture-positive PTB among patients with clinical suspicion were a positive smear test (OR 172; 95% CI 23.23 to 1273.54) and having CXR lesions compatible with PTB (OR 10.401; 95% CI 5.862 to 18.454). The regression model had a good predictive performance for identifying culture-positive PTB among patients with clinical suspicion (area under the curve (AUC) 0.84), but it was rather poor in patients with a negative smear result (AUC 0.64). Combining all the predictors in the model compared with only the independent significant variables did not really improve its performance to identify culture-positive (AUC 0.84–0.87) and culture-negative (AUC 0.64–0.69) PTB.ConclusionsOur finding suggests that predictive models based on clinical variables will not be useful to discriminate patients with culture-negative PTB from patients with culture-positive PTB among patients with smear-negative cases.

Objectives: To determine the frequency of culture positive (SBP) and culture negative spontaneous bacterial peritonitis (neutrocytic ascites) in cirrhotic population. Period: The six months (November 08th 2012 to May 07th 2013). Study Design: Descriptive cross-sectional study. Setting: Department of Gastroenterology at Liaquat National Hospital. Total 107 patients of liver cirrhosis with ascites admitted in our hospital. All the specific patients had ascitic fluid DR and C/S were enrolled and evaluated. Patient’s information was recorded on proforma and analyzed by using SPSS-20.0. Results: SBP was detected in 10 7 patients aged between 18 and 67 years included in study. Out of 107 patients with SBP 23 (21.5%) were culture positive while 84 (78.5%) were culture negative. In the culture positive group,19 (82.6%) were male and 4 (17.4%) were female while in culture negative group 46 (54.76%) were male and 38 (45.24%) were female. The ascitic fluid mean total leukocyte count in patients with culture positive ascites was 5140.39 /mm3 and in culture negative ascites was 2654.26 / mm3. The ascitic fluid mean neutrophils count in subjects with culture positive ascites was 75.57% and in culture negative ascites was 76.02%. The ascitic fluid mean lymphocyte count in individuals had culture positive ascites was 26.09 % and in subjects had culture negative ascites was 23.97%. Conclusion: Frequency of culture negative ascites is greater than culture positive ascites in SBP. The ascitic fluid mean total leucocyte count for culture positive ascites is greater than culture negative ascites. Mortality is high in culture positive ascites.

Abstract Background Shigella spp. and entero-invasive E. coli (EIEC) use the same invasive mechanism to cause diarrheal diseases. Public health regulations apply only to Shigella spp. infections, but are hampered by the lack of simple methods to distinguish them from EIEC. In the last decades, molecular methods for detecting Shigella spp. and EIEC were implemented in medical microbiological laboratories (MMLs). However, shigellosis cases identified with molecular techniques alone are not notifiable in most countries. Our study investigates the impact of EIEC versus Shigella spp. infections and molecular diagnosed shigellosis versus culture confirmed shigellosis for re-examination of the rationale for the current public health regulations. Methods In this multicenter cross-sectional study, fecal samples of patients suspected for gastro-enteritis, referred to 15 MMLs in the Netherlands, were screened by PCR for Shigella spp. or EIEC. Samples were cultured to discriminate between the two pathogens. We compared risk factors, symptoms, severity of disease, secondary infections and socio-economic consequences for (i) culture-confirmed Shigella spp. versus culture-confirmed EIEC cases (ii) culture positive versus PCR positive only shigellosis cases. Results In 2016–2017, 777 PCR positive fecal samples with patient data were included, 254 of these were culture-confirmed shigellosis cases and 32 were culture-confirmed EIEC cases. EIEC cases were more likely to report ingestion of contaminated food and were less likely to be men who have sex with men (MSM). Both pathogens were shown to cause serious disease although differences in specific symptoms were observed. Culture-negative but PCR positive cases were more likely report travel or ingestion of contaminated food and were less likely to be MSM than culture-positive cases. Culture-negative cases were more likely to suffer from multiple symptoms. No differences in degree of secondary infections were observed between Shigella spp. and EIEC, and culture-negative and culture-positive cases. Conclusions No convincing evidence was found to support the current guidelines that employs different measures based on species or detection method. Therefore, culture and molecular detection methods for Shigella spp. and EIEC should be considered equivalent for case definition and public health regulations regarding shigellosis. Differences were found regarding risks factors, indicating that different prevention strategies may be required.

Health And Well Being

Introduction: According to the OECD, Portugal and Poland rank below average in several well-being measures such as income and wealth, and health status. Investigating how people perceive the threats to health in these two countries, is an important issue to address priority needs. To meet this need, the objective of this paper was to compare the perceptions of the threats to the health and well-being among the Polish and Portuguese older persons and explore differences between the countries in respect of patterns of self-rated health.Material and Methods: A Cross-sectional study with two convenience samples from primary health care services of Poland and Portugal was conducted; 480 adults aged 65 and over (247 Portuguese) were included. The EASYCare standard assessment of 2010 was applied under a joint project of both countries. The association between ‘self-rated unhealthy’ and socio-demographic and threats to health variables was examined using logistic regression.Results: In both countries about two thirds of the older persons self-rated their health as unhealthy. Having more than enough finances was associated with a significant lower odds of being unhealthy compared with those without enough finances at the end of the month (Portugal: OR = 0.25, 95% CI 0.10 to 0.63; Poland: OR = 0.33, 95% CI 0.12 to 0.88). Visual problems, bodily pain, memory loss, feeling bored or lonely and reporting shortness of breath during normal activities was consistently associated with fair or poor self-rated health.Discussion: These findings provide important information regarding the health profile of older people which can help in the development of people-centred health systems where their lives and well-being can be improved. Conclusion: The unhealthy perception of older people was consistently associated with indicators of major health threats.

Objective: The objective of this study was to determine and characterize caregiver burden among caregivers of community-dwelling older persons in Jamaica. Method: A nationally representative cross-sectional study was done among persons providing noninstitutional care for a single person (≥60 years). The Zarit Burden Interview (ZBI) and a structured questionnaire were administered to 180 caregivers from four geographic health regions. Results: The ZBI scores ranged from 0 to 56 (median = 15). Independently associated factors were relationship to care recipient and age. Children/grandchildren had higher caregiver burden scores than formally employed caregivers (odds ratio = 2.9: 95% confidence interval: [1.02, 8.34]). Compared with caregivers 35 to 44 years, those aged 45 to 65 were almost 5 times more likely to report higher caregiver burden scores. Conclusion: Caregiver burden as identified by the ZBI was low. Age (45–65 years) and being the child/grandchild of the care recipient were independently associated with greater caregiver burden. Interventions to address caregiver burden must embrace strategies that recognize that these factors.
