Abstract Background In populations above 3,000 meters above sea level (m.a.s.l.) normal values of oxygen saturation (SpO2) above 90% have been reported. Few studies have been conducted in cities of moderate altitude (between 2,500 and 3,000 m a.s.l). We set out to describe the range of SpO2 values measured with a pulse oximeter in healthy children between 1 month and 12 years of age living in an Ecuadorian Andean city. Methods A cross-sectional study was carried out in Quito, Ecuador, located at 2,810 m a.s.l. SpO2 measurement in healthy children of ages ranging from 1 month to 12 years of age residents in the city were recorded by pulse oximetry. Age and gender were recorded, and median and 2.5th and 5th percentile were drawn. Non parametric tests were used to compare differences in SpO2 values by age and gender. Results 1,378 healthy children were included for the study, 719 (52.2%) males. The median SpO2 for the entire population was 94.5%. No differences were observed between SpO2 median values by age and gender. The 2.5th percentile for global SpO2 measurements was 90%, in children under 5 years of age was 91% and it was 90% in children older than 7. Conclusions Our results provide SpO2 values for healthy children from 1 to 12 years old residents in Quito, a city of moderate altitude. The SpO2 percentile curve could contribute as a healthy range for the clinical evaluation of children residing at this altitude.

Results 1378 healthy children were eligible for the study, 719 (52.2%) males. Average SpO2 for the entire population was 94.5% (SD 1.70; 95%CI 94.41–94.59). No differences were observed between SpO2 values by age and gender. The SpO2 2.5 percentile value in the whole was 90%, in children under 5 years of age was 91% and it was 90% in children older than 7. Conclusions In cities of moderate altitude, the SpO2 percentile measures developed in healthy children may contribute to an improved decision-making process, especially in cases where resource availability is limited.

Abstract Background Bone turnover and metabolic indicators are related to age and gender. Age and gender should be matched in subjects in disease control research of bone turnover and metabolism, but strict matching of gender and age increases the difficulty and cost of the research. Therefore, the aim of this study was to solve it is necessary to strictly match age and gender in clinical research in bone metabolism. Methods A cross-sectional study was conducted from the data were extracted from the HIS of ZhuJiang Hospital. Data relating to seven bone turnover and metabolic indicators from 1036 patients between January 2018 and October 2019 were analyzed. Results P1NP, β-CTx and 25(OH)D were significant different in individuals younger than 20 years of age. ALP was significantly higher in those under 20 years of age and lower at age 20–39 compared with other age groups. The concentrations of Ca and P were different among the groups aged 0–19, 20–39, and 40–59 years of age groups but exhibited no difference above 60 years of age. PTH expression was not dependent on age. P1NP, β-CTx and PTH concentrations were not significantly different between the genders within the same age group. ALP was significantly different between genders within the age range 20–59 years. Ca and 25(OH)D were significantly different between the genders for those older than 60. Serum P was significantly different in the two genders for those aged 40–79. Patients received both alfacalcidol and calcium treatment differently from the others in P1NP, β-CTx, Serum Ca, P and ALP. Conclusion P1NP and β-CTx were highly correlated with age. If these two indictors require analysis in a case control study, the patients and controls should be strictly matched by age under 20 years. The demarcation point for ALP was 40 years of age. Ca and P were strongly recommended strict matching according to age in disease research. The difference in P1NP, β-CTx, 25(OH)D and ALP between genders depends on age differences. Medication history should be considered in bone turnover and metabolic clinical research.

A cross-sectional study of new clients with either gonorrhoea or chlamydia attending King's College Hospital in 1998. One thousand two hundred and thirty-nine women and 1141 men had gonorrhoea, chlamydia or both. Overall, 24.2% (124/512) of heterosexual men and 38.5% (136/353) of women with gonorrhoea also had chlamydia ( P<0.001). Of heterosexual males 18.8% (124/660) and 13% (136/1022) of females with chlamydia also had gonorrhoea ( P=0.002). Ethnicity had no effect on the proportion of co-infection after controlling for age and gender. Clients with dual infection were younger than those with either infection alone ( P=0.0001). Over half of women and a quarter of men aged 15 to 19 years were dually infected so testing for both gonorrhoea and chlamydia may be appropriate in this age group in settings outside genitourinary clinics. The high proportion of cases of gonorrhoea that also have chlamydia justifies the policy of epidemiological treatment for chlamydia.
