Disseminated abscesses due to group Gβ-hemolyticStreptococcus dysgalactiaewere observed in a 57-year-old cirrhotic patient with the skin being the putative way of entry for the pathogen.S. dysgalactiaeis a rare agent in human infections responsible for acute pyogenic meningitis. The mortality rate associated withS. dysgalactiaebacteraemia and meningitis may be as high as 50%, particularly in the presence of endocarditis or brain abscesses. In our patient, main sites of infections were meningitis and ventriculitis, spondylodiscitis, septic arthritis, and soft-tissue infections. In contrast, no endocarditis was evidenced. Cirrhosis-related immune suppression was considered as a pathophysiological cofactor for the condition. Fortunately, clinical status improved after long-term (3 months) antimicrobial therapy.

BACKGROUND In the span of COVID-19, the mortality rate has been different from one country to another. As a country in the Middle East Iraq has a critical position, lies between Iran and Turkey while both countries coronavirus cases increase on daily basis, while Iranian mortality rate record is high similar to Turkey. After Wuhan city of China, Lombard of Italy, Qum city in Iran has the highest number of COVID-19 as a first country in the Middle East. OBJECTIVE aim of this study is to show the effect of BCG vaccine during pandemic diseases, especially nowadays at the time of COVID-19. One of the crucial observations is the government preparedness and strategic planning prior pandemics, in which the BCG vaccine is an attenuated live vaccine for control of tuberculosis (TB). BCG vaccine has a non-specific immune effect that is used against pathogens like bacteria and viruses, through the promotion of pro-inflammatory cytokines' secretion. METHODS An epidemiological study has been performed, and it shows that some countries are more prone to contagious diseases like COVID-19, regardless of the main cultural, religious, societal similarities among the three mentioned countries. The information data has been collected from WHO reports and worldometer in 18 February 2020 to 10 May 2020. Regarding the efficacy of the BCG vaccine, relevant data has been retrieved from Google scholar, Pub-med and BCG world-atlas. RESULTS COVID-19 mortality rates are at peak in Iran and Turkey while the mortality rate is very low in Iraq, while the patients that died in Iraq all had history of other long-term diseases as heart disease, blood pressure, cancer etc. CONCLUSIONS From the experiences of the three countries in the life span of COVID-19, the historical plan of BCG vaccine in Iraq in cooperation with WHO since the last decades it shows that COVID-19 mortality rate is lower than other countries due to the early vaccination of the Iraqis, otherwise Iraq is more fragile than Iran and Turkey due to the poor conditions of Iraq in terms of economics, politics, war and other aspects.

AbstractNocardia brain abscess is a rare clinical entity, accounting for 2% of all brain abscesses, associated with high morbidity and a mortality rate 3 times higher than brain abscesses caused by other bacteria. Proper investigation and treatment, characterized by a long-term antibiotic therapy, play an important role on the outcome of the patient. The authors describe a case of a patient without neurological comorbidities who developed clinical signs of right occipital lobe impairment and seizures, whose investigation demonstrated brain abscess caused by Nocardia spp. The patient was treated surgically followed by antibiotic therapy with a great outcome after 1 year of follow-up.

Background: Available data comparing long-term prognosis according to the type of acute coronary syndrome (ACS) are scarce, contradictory, and outdated. Our aim was to compare short- and long-term mortality in ST-elevated (STEMI) and non-ST-elevated myocardial infarction (non-STEMI) ACS patients. Methods: Patients presenting with an inaugural ACS during the year 2006 and living in one of the three areas in France covered by the Monitoring of Trends and Determinants in Cardiovascular Disease (MONICA) registry were included. Results: A total of 1822 patients with a first ACS—1121 (61.5%) STEMI and 701 (38.5%) non-STEMI—were included in the study. At the 28-day follow-up, the mortality rates were 6.7% and 4.7% (p = 0.09) for STEMI and non-STEMI patients, respectively, and after adjustment of potential confounding factors, the 28-day probability of death was significantly lower for non-STEMI ACS patients (Odds Ratio = 0.58 (0.36–0.94), p = 0.03). At the 10-year follow-up, the death rates were 19.6% and 22.8% (p = 0.11) for STEMI and non-STEMI patients, respectively, and after adjustment of potential confounding factors, the 10-year probability of death did not significantly differ between non-STEMI and STEMI events (OR = 1.07 (0.83–1.38), p = 0.59). Over the first year, the mortality rate was 7.2%; it then decreased and stabilized at 1.7% per year between the 2nd and 10th year following ACS. Conclusion: STEMI patients have a worse vital prognosis than non-STEMI patients within 28 days following ACS. However, at the 10-year follow-up, STEMI and non-STEMI patients have a similar vital prognosis. From the 2nd year onwards following the occurrence of a first ACS, the patients become stable coronary artery disease patients with an annual mortality rate in the 2% range, regardless of the type of ACS they initially present with.

Background: Several countries have documented the relationship between long-term exposure to air pollutants and epidemiological indicators of the COVID-19 pandemic, such as incidence and mortality. This study aims to explore the association between air pollutants, such as PM2.5 and PM10, and the incidence and mortality rates of COVID-19 during 2020. Methods: The incidence and mortality rates were estimated using the COVID-19 cases and deaths from the Chilean Ministry of Science, and the population size was obtained from the Chilean Institute of Statistics. A chemistry transport model was used to estimate the annual mean surface concentration of PM2.5 and PM10 in a period before the current pandemic. Negative binomial regressions were used to associate the epidemiological information with pollutant concentrations while considering demographic and social confounders. Results: For each microgram per cubic meter, the incidence rate increased by 1.3% regarding PM2.5 and 0.9% regarding PM10. There was no statistically significant relationship between the COVID-19 mortality rate and PM2.5 or PM10. Conclusions: The adjusted regression models showed that the COVID-19 incidence rate was significantly associated with chronic exposure to PM2.5 and PM10, even after adjusting for other variables.

Abstract Background Control in COPD is a dynamic concept that can reflect changes in patients’ clinical status that may have prognostic implications, but there is no information about changes in control status and its long-term consequences. Methods We classified 798 patients with COPD from the CHAIN cohort as controlled/uncontrolled at baseline and over 5 years. We describe the changes in control status in patients over long-term follow-up and analyze the factors that were associated with longitudinal control patterns and related survival using the Cox hazard analysis. Results 134 patients (16.8%) were considered persistently controlled, 248 (31.1%) persistently uncontrolled and 416 (52.1%) changed control status during follow-up. The variables significantly associated with persistent control were not requiring triple therapy at baseline and having a better quality of life. Annual changes in outcomes (health status, psychological status, airflow limitation) did not differ in patients, regardless of clinical control status. All-cause mortality was lower in persistently controlled patients (5.5% versus 19.1%, p = 0.001). The hazard ratio for all-cause mortality was 2.274 (95% CI 1.394–3.708; p = 0.001). Regarding pharmacological treatment, triple inhaled therapy was the most common option in persistently uncontrolled patients (72.2%). Patients with persistent disease control more frequently used bronchodilators for monotherapy (53%) at recruitment, although by the end of the follow-up period, 20% had scaled up their treatment, with triple therapy being the most frequent therapeutic pattern. Conclusions The evaluation of COPD control status provides relevant prognostic information on survival. There is important variability in clinical control status and only a small proportion of the patients had persistently good control. Changes in the treatment pattern may be relevant in the longitudinal pattern of COPD clinical control. Further studies in other populations should validate our results.

Background: Liver resection, or pancreaticoduodenectomy, has traditionally been thought to have a high morbidity and. mortality rate among the elderly. Recent improvements in surgical and anesthetic techniques, an increasing number of elderly patients, and an increasing need to justify use of limited health care resources prompted an assessment of recent surgical outcomes.Methods: Five hundred seventy-seven liver resections (July 1985–July 1994) performed for metastatic colorectal cancer and 488 pancreatic resections (October 1983–July 1994) performed for pancreatic malignancies were identified in departmental data bases. Outcomes of patients younger than age 70 years were compared with those of patients age 70 years or older.Results: Liver resection for 128 patients age 70 years or older resulted in a 4% perioperative. mortality rate and a 42% complication rate. Median hospital stay was 13 days, and 8% of the patients required admission to the intensive care unit (ICU). Median survival was 40 months, and the 5-year survival rate was 35%. No difference were found between results for the elderly and those for younger patients who had undergone liver resection, except for a minimally shorter hospital stay fortheyoungerpatients (median, 12 days vs. 13 days p=0.003). Pancreatic resection for 138 elderly patients resulted in a mortality rate of 6% and a complication rate of 45%. Median stay was 20 days, and 19% of the patients required ICU admission, results identical to those for the younger cohort. Long-term survival was poorer for the elderly patients, with a 5-year survival rate of 21% compared with 29% for the younger cohort (p=0.03).Conclusions: Major liver or pancreatic resections can be performed for the elderly with acceptable morbidity and mortality rates and possible long-term survival. Chronologic age alone is not a contraindication to liver or pancreatic resection for malignancy.

ABSTRACT The environment is the likely source of most nontuberculous mycobacteria (NTM) involved in human infections, especially pulmonary, skin, and soft tissue infections. In order to measure the prevalence of NTM in different aquatic ecosystems, we tried to standardize the culture methods used for surface water testing since many procedures have been described previously. Cultivation of mycobacteria requires long-term incubation in rich media and inactivation of rapidly growing microorganisms whose growth impedes observation of mycobacterial colonies. Consequently, the two criteria used for evaluation of the methods examined were (i) the rate of inhibition of nontarget microorganisms and (ii) the efficiency of recovery of mycobacteria. We compared the competitive growth of Mycobacterium chelonae and M. avium with nontarget microorganisms on rich Middlebrook 7H11-mycobactin medium after treatment by several chemical decontamination methods that included acids, bases, detergent, or cetylpyridinium chloride (CPC) with and without an antibiotic cocktail, either PANTA (40 U/ml polymyxin, 4 μg/ml amphotericin B, 16 μg/ml nalidixic acid, 4 μg/ml trimethoprim, and 4 μg/ml azlocillin) or PANTAV (PANTA plus 10 μg/ml vancomycin). Our results showed that treatment for 30 min with CPC (final concentration, 0.05%) of water concentrated by centrifugation, followed by culture on a rich medium supplemented with PANTA, significantly decreased the growth of nontarget microorganisms (the concentrations were 6.2 � 0.4 log10 CFU/liter on Middlebrook 7H11j medium and 4.2 � 0.2 log10 CFU/liter on Middlebrook 7H11j medium containing PANTA [P < 0.001]), while the effect of this procedure on NTM was not as great (the concentrations of M. chelonae on the two media were 7.0 � 0.0 log10 CFU/liter and 6.9 � 0.0 log10 CFU/liter, respectively, and the concentrations of M. avium were 9.1 � 0.0 log10 CFU/liter and 8.9 � 0.0 log10 CFU/liter, respectively). We propose that this standardized culture procedure could be used for detection of NTM in aquatic samples.
