Increase in methicillin-resistant Staphylococcus spp. colonization among pregnant individuals during COVID-19 pandemic.

Methicillin-resistant Staphylococcus (MRS) has been associated with neonatal infections, with colonization of the anovaginal tract being the main source of vertical transmission. The COVID-19 pandemic has altered the frequency of antibiotic usage, potentially contributing to changes in the dynamics of bacterial agents colonizing humans. Here we determined MRS colonization rates among pregnant individuals attending a single maternity in Rio de Janeiro, Brazil before (January 2019-March 2020) and during (May 2020-March 2021) the COVID-19 pandemic. Anovaginal samples (n = 806 [521 samples before and 285 during the pandemic]) were streaked onto chromogenic media. Colonies were identified by MALDI-TOF MS. Detection of mecA gene and SCCmec typing were assessed by PCR and antimicrobial susceptibility testing was done according to CLSI guidelines. After the onset of the pandemic, MRS colonization rates increased significantly (p < 0.05) from 8.6% (45) to 54.7% (156). Overall, 215 (26.6%) MRS isolates were detected, of which S. haemolyticus was the most prevalent species (MRSH, 84.2%; 181 isolates). SCCmec type V was the most frequent among MRS (63.3%; 136), and 31.6% (68) of MRS strains had a non-typeable SCCmec, due to new combinations of ccr and mecA complexes. Among MRS strains, 41.9% (90) were resistant to at least 3 different classes of antimicrobial agents, and 60% (54) of them were S. haemolyticus harboring SCCmec V. MRS colonization rates and the emergence of multidrug-resistant variants detected in this study indicate the need for continuing surveillance of this important pathogen within maternal and child populations.

Peptic ulceration in general practice in England and Wales 1994-98: period prevalence and drug management.

BACKGROUND: Little is known about the burden of peptic ulcer in the community. AIMS: To examine recent time trends in the period prevalence of peptic ulceration and its drug management, in England and Wales. METHODS: For each year between 1994 and 1998, information on patients with a diagnosis of peptic ulceration was extracted from the General Practice Research Database. RESULTS: The annual age-standardized period prevalence of peptic ulceration decreased from 3.3/1000 in 1994 to 1.5/1000 in 1998 for men, and from 1.8/1000 to 0.9/1000 for women. This decline was more evident among younger people, and among males registered with practices located in the most deprived electoral wards compared to those located in the least deprived. The proportion of patients receiving H2 receptor antagonists declined from 68% in 1994 to 41% in 1998. In contrast, the proportion prescribed proton pump inhibitors rose from 46% to 66%. CONCLUSIONS: Over a 5-year period, the period prevalence of peptic ulceration has decreased markedly, especially among younger people and those from more deprived areas.

Acute and chronic pancreatitis--diseases on the rise: a study of hospital admissions in England 1989/90-1999/2000.

BACKGROUND: The number of hospital admissions for acute and chronic pancreatitis increased in Britain from the 1960s to the 1980s. AIMS: To determine time trends in acute and chronic pancreatitis for hospital admissions from 1989/90 to 1999/2000, mortality from 1979 to 1999, and various indices of alcohol consumption. METHODS: Hospital Episode Statistics for admissions were obtained from the Department of Health and mortality data from the Office for National Statistics. Alcohol consumption data were obtained from the General Household Survey. RESULTS: Between 1989/90 and 1999/2000, age-standardized hospital admission rates for acute pancreatitis increased by 43%, whilst those for chronic pancreatitis rose by 100%. The proportions of admissions requiring surgical operations increased for acute pancreatitis, but declined for chronic pancreatitis. Case fatality rates for acute pancreatitis declined, but mortality statistics showed no significant change. The proportion of women who drank more than 14 units of alcohol a week also increased. CONCLUSIONS: There has been a steady increase in admission rates for both acute and chronic pancreatitis over the study period, and these conditions will become an increasingly important part of the workload of the gastroenterologist.

Gallstones--an increasing problem: a study of hospital admissions in England between 1989/1990 and 1999/2000.

BACKGROUND: The number of operations for cholelithiasis increased from the 1950s to the 1990s. AIMS: To determine the time trends in cholelithiasis for hospital admissions, operations and in-hospital case fatalities in England between 1989/1990 and 1999/2000, and population mortality rates between 1979 and 1999. METHODS: Hospital Episode Statistics for admissions were obtained from the Department of Health and mortality data were obtained from the Office for National Statistics. RESULTS: Between 1989/1990 and 1999/2000, age-standardized hospital admission rates for cholelithiasis increased by 30% for males and 64% for females. The proportions of admissions undergoing an operation declined progressively over the study period. In 1999/2000, the frequency of operation was approximately 50-60% for most age groups, but decreased progressively with advancing age at > or = 65 years. The proportions of admissions undergoing therapeutic endoscopy increased several-fold, especially amongst older individuals. Case fatality rates declined. Mortality rates declined from 1979 to 1988, but showed no further change from 1989 to 1999. CONCLUSIONS: There has been a steady increase in admission rates for cholelithiasis over the study period. Whilst the frequency of operation has declined, the proportion of patients undergoing therapeutic endoscopy has increased.

Diverticular disease of the colon--on the rise: a study of hospital admissions in England between 1989/1990 and 1999/2000.

BACKGROUND: Diverticular disease emerged as a common problem in Western countries over the course of the 20th century. AIMS: To determine the time trends in diverticular disease for hospital admissions in England between 1989/1990 and 1999/2000 and population mortality rates from 1979 to 1999. METHODS: Hospital Episode Statistics were obtained from the Department of Health and mortality data from the Office for National Statistics. RESULTS: Between 1989/1990 and 1999/2000, annual age-standardized hospital admission rates for diverticular disease increased by 16% for males (from 20.1 to 23.2 per 100,000) and 12% for females (from 28.6 to 31.9 per 100,000). Female rates were significantly higher than male rates throughout the study period. The proportions of admissions with an operation increased by 16% for males (from 22.9% to 24.1%) and 14% for females (from 19.7% to 22.3%). Older patients were less likely to undergo operation than younger patients. In-patient case fatality rates and population mortality rates remained unchanged. CONCLUSIONS: Admission rates for diverticular disease increased over the study period. The proportion of patients who underwent operation increased, but in-patient and population mortality rates remained unchanged. With an ageing population, diverticular disease will become an increasingly important clinical problem in England.
