[Comparative studies on activities of antimicrobial agents against causative organisms isolated from patients with urinary tract infections (2001). III. Secular changes in susceptibility].

The bacteria (Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Klebsiella spp. and Pseudomonas aeruginosa) isolated from patients diagnosed as urinary tract infections (UTIs) in 10 institutions in Japan were supplied between September and December, 2001. Then, the susceptibilities of these bacteria to various antimicrobial agents were examined, and the results were compared with those obtained between 1992 and 2000. Comparison was made by classifying strains isolated from patients into those in uncomplicated UTIs and those in complicated UTIs (including with or without indwelling catheter). The drug sensitivity of S. aureus in this year was comparable to those in up to the previous year, and S. aureus showed the best susceptibility to vancomycin (VCM). E. faecalis showed good susceptibility to ampicillin and imipenem, and the MIC90s were 2 micrograms/mL. The susceptibility of E. faecalis to VCM was also good. E. coli showed good susceptibility to the drugs except penicillins. Among cephems, the susceptibility to cefozopran (CZOP) was better (MIC90: < or = 0.125 microgram/mL). Just as the last report, the decreases in susceptibility of E. coli to quinolones were also observed in the patients with complicated UTIs. The susceptibility of Klebsiella spp. to all the test drugs did not significantly change in 2001 and was generally good but not to penicillins. Among cephems, Klebsiella spp. showed good susceptibility to flomoxef, cefpirome, cefixime, and CZOP with < or = 0.125 microgram/mL of MIC90s either in uncomplicated or complicated UTIs. Although the drug sensitivity of P. aeruginosa was generally low, the detection of the strains that showed good susceptibility to quinolones and carbapenems (MIC: < or = 0.125-2 micrograms/mL) were relatively frequent.

Infant mortality in Greenland: secular trend and regional variation.

Infant mortality and stillbirths were studied in the Inuit population of Greenland. Infant mortality rate decreased from 110 per 1000 live births in 1951 to 50 in 1970 and 20 in 1989. Statistically significant decrease was in particular seen for acute respiratory infections and certain perinatal conditions. Both perinatal and postperinatal mortality rates increased significantly with remoteness from the capital and were higher in settlements than in towns. The overall trend in Greenland is similar to the Danish pattern 30 years earlier, but there was pronounced regional variation. In towns, the infant mortality rate decreased continuously while in settlements an initial decrease was followed by a substantial increase during 1980-87 when the mortality rate doubled. The greater part of this increase could be attributed to an increased number of deaths in the postperinatal period countrywide during 1981-84 and an increased number of perinatal deaths in the settlements of one particular municipality during 1983-86.

Prevalence and 10-year secular trend of obesity in Oman.

OBJECTIVE: To determine the prevalence of overweight and obesity by age, gender and region and to assess the difference between rural and urban populations and determine the trends of the past decade. METHODS: Analysis of nationally represented samples from 2 cross-sectional surveys conducted in 1991 and 2000, containing 5,086 and 6,400 Omani citizens aged >or=20 years. Body mass index (BMI) (weight in kg) divided by height (in meters squared) was calculated using measured height and weight data. Overweight was defined as BMI 25-29.9 kg/m2 and obesity as BMI >or= 30 kg/m2. RESULTS: In the year 2000, the age adjusted prevalence of obesity reached 16.7% in men, compared to 10.5% in 1991 (p<0.001). In women, the prevalence was 23.8% in 2000, compared to 25.1% in 1991 (p=0.231). Similarly, the prevalence of overweight increased among men, from 28.8-32.1% (p=0.011) and decreased among women, from 29.5-27.3% (p=0.053). When obesity and overweight were combined, there was a significant increase in men (9.5%; p for the change <0.001) and decrease in women (3.5%; p for the change <0.003). Obesity and overweight combined was markedly more common in the Southern part of Oman (70%) compared to Northern areas (32-57%). People living in urban areas were more obese (21.1%) than those living in the rural communities (13.1%) (p<0.001). CONCLUSION: The prevalence of obesity is high in Oman and has increased predominantly among men. Primary prevention programs are needed to counteract this condition and its cardiovascular and metabolic complications.

Secular change in newborn adiposity in an urban hospital.

Triceps and subscapular skinfold thickness were measured in 1080 consecutive newborns and the values were compared with an earlier study reported in 1981 from the same institution. The skinfold thickness in the present study was higher at all gestational age groups (except for 41 weeks) in both sexes. These differences were statistically significant at all periods except for males at 38 weeks and females at 39 weeks. For term infants, the mean skin fold thickness (subscapular and triceps) was significantly higher among both males (3.5 mm vs 4.0 mm; p< 0.05) and females (3.9 mm vs. 4.2 mm; p <0.05). The subscapular skin fold thickness in both males and females and triceps skin fold thickness in females were also significantly higher for all birthweight categories. The data suggests an increase in adiposity among newborns, over a period of two decades, in an urban poor population.

[Comparative studies on activities of antimicrobial agents against causative organisms isolated from patients with urinary tract infections (2002). III. Secular changes in susceptibility].

The bacteria (Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Klebsiella spp. and Pseudomonas aeruginosa) isolated from patients diagnosed as urinary tract infections (UTIs) in 13 institutions in Japan were supplied between August 2002 and July 2003. The susceptibilities of these bacteria to various antimicrobial agents were examined. The bacteria were divided into 2 groups consisting of uncomplicated UTIs and complicated UTIs (with and without indwelling catheter) based on their isolation origins. The results were compared with those obtained between 1993 and 2001. The drug sensitivity of S. aureus in this year was similar to those in up to the previous year and S. aureus showed the best susceptibility to vancomycin. The drug sensitivity of E. faecalis in this year also was similar to those in up to the previous year. The drug sensitivity of E. coli in this year was generally good except penicillins and was similar to those in up to the previous year. Among cephems, cefozopran (CZOP) and cefpirome (CPR) showed the highest potency (MIC90: < or = 0.125 microg/mL). An antibacterial activity of cefotiam (CTM) was similar to it in 10 years ago and was fine (MIC90: < or = 1 microg/mL). The sensitivity of E. coli to carbapenems and carumonam (CRMN) also was good like to CZOP. However, the sensitivity of the complicated UTIs group to quinolones decreased after 2000 and was suggested to develop the resistance to the drug. The drug sensitivity of Klebsiella spp. in this year also was similar to those in up to the previous year. The bacteria showed good susceptibility (MIC: < or = 0.125 microg/mL) to cefmenoxime (CMX), CPR, cefixime (CFIX), flomoxef (FMOX), and CZOP among cephems. The drug sensitivity of P. aeruginosa was generally low. Most of the bacteria were little sensitive to cephems except CZOP and ceftazidime (CAZ). The sensitive bacteria to CZOP and ceftazidime (CAZ) were observed to be 26.8% (15/56 strains) and 39.3% (22/56 strains) in complicated UTIs group, respectively. The sensitivity profile of P. aeruginosa to the other tested drugs was not much different from that in up to the previous year. However, the sensitivity of the bacteria to carbapenems tended to decrease after 2000, and the low sensitive strains (MIC: > or = 256 microg/mL) were detected at 22.2% (2/9 strains) in the uncomplicated UTIs group and 3.6% (2/56 strains) in the complicated UTIs group.

[Secular trends of weight in Portugal at the end of the 20th century].

Obesity and the associated mortality and morbidity constitute one of the major problems and challenges for Public Health systems in Western countries. The majority of published studies show a progressive increase of obesity prevalence, that assumes even an higher importance in younger groups. This study aims to assess the trends in height, weight and body mass index (BMI) in young men in Portugal, in the last ten years. We extracted data from military census records of medical inspections 1994-95 (81,363 subjects) and 1998-99 (71,254 subjects). The data included recruitment center, age, weight, height and BMI. The results showed an increase of weight, height and body mass index between 1995 and 1999 (p<0.001). In 1995 the percentage of subjects with a BMI equal or higher than 25 was 15% and in 1999 was 22%. The percentage of subjects with a BMI higher than 30 was 1.4% and 2.3%, respectively. According to these results obesity and overweight prevention programs and therapeutic strategies must continue to be a major issue in health politics.

[Comparative studies on activities of antimicrobial agents against causative organisms isolated from patients with urinary tract infections (2003). III. Secular changes in susceptibility].

The bacteria (Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Klebsiella spp. and Pseudomonas aeruginosa) isolated from 565 patients diagnosed as urinary tract infections (UTIs) in 14 institutions in Japan were collected between August 2003 and July 2004. The susceptibilities of these bacteria to various antimicrobial agents were examined. The bacteria were divided into 2 groups consisting of uncomplicated UTIs and complicated UTIs (with and without indwelling catheter) based on their isolation origins. The results were compared with those obtained between 1994 and 2002. The drug sensitivity of S. aureus in this year was similar to those in up to the previous years and S. aureus showed the best susceptibility to vancomycin. The drug sensitivity of E. faecalis in this year also was similar to those in up to the previous years. The drug sensitivity of E. coli in this year was generally good except penicillins and was similar to those in up to the previous years. Among cephems, cefozopran (CZOP) and cefpirome (CPR) showed the highest potency activity (MIC90: < or = 0.125 microg/mL). An antibacterial activity of cefotiam (CTM) was stable for 10 years and was fine (MIC0: < or = 0.5 microg/mL). The sensitivity of E. coli to carbapenems and carumonam (CRMN) also was good like to CZOP. The sensitivity of the complicated UTIs group to quinolones, however, has decreased after 2000 and it was suggested that the resistance to the drug has developed. Kiebsiella spp. showed a decrease in the susceptibility to some of cephems. The drugs indicating a big decrease in the sensitivity were cefazolin, CTM, cefaclor, and cefpodoxime. Imipenem, carbapenems, also indicated a decrease in the sensitivity. The susceptibility of the strain to the other drugs was similar to that in up to the previous years. Among them, CZOP maintained good susceptibility (MIC90: > or = 0.125 microg/mL against uncomplicated UTIs, 0.25 microg/mL against complicated UTIs) like meropenem. The drug sensitivity of P. aeruginosa was generally low and was not much different from that in up to the previous years.

Secular trends in risk behaviour of Cape Town grade 8 students.

OBJECTIVE: To compare prevalence rates of selected risk behaviours and age of first intercourse of grade 8 students in Cape Town between 1997 and 2004. DESIGN: Cross-sectional surveys in 1997 and 2004. Survival analysis was used to estimate the cumulative incidence of first intercourse. The log-rank statistic was used to compare the survival distributions. When comparing data from the two studies we used a logistic regression model with the factors year, race and age group to test the difference in reported risk behaviours between 1997 and 2004 within each gender. SETTING: Public high schools in Cape Town. SUBJECTS: Multistage cluster samples of 1 437 and 6 266 grade 8 students in 1997 and 2004 respectively. OUTCOME MEASURES: Ever having had sexual intercourse; for those that had, whether any method was used to prevent pregnancy or disease at last intercourse, and (if so) what was used; use of tobacco, alcohol and marijuana; violence-related behaviours; and suicidal behaviour. RESULTS: There was a significant delay in first intercourse in 2004 compared with 1997. For males, levels of condom use were lower in 2004 than in 1997, while for females levels of injectable contraceptive use were lower. There were significant increases in past month use of cigarettes for males and marijuana for both genders. Rates of perpetration of violence behaviour remained stable or decreased from 1997 to 2004, while the rate of suicidal behaviour for males increased. CONCLUSIONS: School-based interventions that address sexual risk behaviours should be expanded to include other risk behaviours.

[Comparative studies on activities of antimicrobial agents against causative organisms isolated from patients with urinary tract infections (2004). III. Secular changes in susceptibility].

The bacteria (Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Klebsiella spp. and Pseudomonas aeruginosa) isolated from patients diagnosed as urinary tract infections (UTIs) in 14 institutions in Japan were collected between August 2004 and July 2005. The susceptibilities of these bacteria to various antimicrobial agents were measured. The bacteria were divided into 2 groups consisting of uncomplicated UTIs and complicated UTIs (with and without indwelling catheter) based on their isolation origins. The results were compared with those obtained between 1995 and 2003. The drug sensitivity of S. aureus in this year was similar to those in up to the previous year and S. aureus showed the best susceptibility to vancomycin (VCM) and arbekacin (ABK). The drug sensitivity of E. faecalis in this year also was similar to those in up to the previous year. The susceptibility of E. coli to cephems in this year was generally good and was similar to those in up to the previous year. MIC90 of cefozopran (CZOP) was the most stable and 0.125 microg/mL or less since 1995. The susceptibility of E. coli to cefpirome (CPR) and cefotiam (CTM) also was good but to cefaclor (CCL), cefixime (CFIX), and cefpodoxime (CPDX) was largely decreased in complicated UTI groups. The sensitivity of E. coli to carbapenems also was good but to carumonam (CRMN) tended to decrease. The susceptibility of E. coli to quinolones, however, has largely changed and has decreased since 2003 in uncomplicated UTIs and 2000 in complicated UTIs. That was suggested the development of the resistance to the drug. The susceptibility of Klebsiella spp. to cefazolin (CEZ), CTM, CCL, CPDX, and cefditoren (CDTR) decreased in the previous year and recovered to the year before the previous year in this year. The susceptibility of Klebsiella spp. to other cephems was stable since 1995, especially against CZOP, the highest sensitivity (MIC90: < or = 0.125 microg/mL) was maintained. The susceptibility of Klebsiella spp. to carbapenems and CRMN also was good. The susceptibility of Klebsiella spp. to aminoglycosides was lower than to CZOP but was stable since 1995. The susceptibility of P. aeruginosa was generally low and has largely changed against the majority of the agents since 1995. The susceptibility of P. aeruginosa isolated from uncomplicated UTIs has largely changed against ceftazidime (CAZ), cefsulodin (CFS), CZOP, imipenem (IPM), meropenem (MEPM), aztreonam (AZT), CRMN, gentamicin (GM), and tobramycin (TOB). The susceptibility of P. aeruginosa isolated from complicated UTIs has largely changed against CSF, CZOP, MEPM, GM, and ciprofloxacin (CPFX). The susceptibility of P. aeruginosa isolated from complicated UTIs has been stable against amikacin (AMK). For annual changes in MIC50, TOB and IPM had a relatively stable and high activity (MIC50: 0.5-2 microg/mL).
