Obesity increases the likelihood of total joint replacement surgery among younger adults.

We conducted a retrospective review of medical charts of patients, aged 18 to 59 years old, who underwent either a total knee replacement (TKR) or total hip replacement (THR) from January 2002 to December 2004. Of the 204 study subjects, 52% had a TKR while 48% had a THR. Obesity was significantly associated with the need for a TKR or THR when comparing the study group to adults of similar age in the general population (P< 0.0001). Seventy-two percent (146) of the study group was obese and 21% (42) overweight (BMI 25.0 to 29.9 kg/m(2)) compared to only 26% (596) obese and 34% (732) overweight in the general population. Patients undergoing a TKR were significantly more likely to be obese (BMI>30 kg/m(2)) than those having a THR, 83% (89) compared to 59% (57) (P< .0006). Our findings support those previously observed in the elderly population. Primary and secondary prevention programs aimed at reducing obesity are strongly recommended.

Estimating the proportion of community-associated methicillin-resistant Staphylococcus aureus: two definitions used in the USA yield dramatically different estimates.

The objective of this retrospective study was to compare the prevalence of community-associated methicillin-resistant Staphylococcus aureus (CAMRSA) and healthcare-associated MRSA (HAMRSA) using healthcare risk factor exposure criteria with that obtained using Centers for Disease Control and Prevention (CDC) criteria. Cases were defined as CAMRSA or HAMRSA based on the general CDC guidelines for nosocomial infections, and then re-assessed with healthcare risk factor exposure criteria using a medical chart review. One hundred MRSA cases occurred at a mid-Western veterans affairs medical centre from November 2001 to November 2003. The proportion of these cases classified as CAMRSA differed dramatically when classified by healthcare risk factor exposure criteria (5%) compared with CDC nosocomial infection criteria (49%). Estimating the role of healthcare-related exposures and developing strategies to control MRSA can be markedly affected by the criteria used to determine CAMRSA and HAMRSA.

Patients' attitudes and comfort levels regarding medical students' involvement in obstetrics-gynecology outpatient clinics.

PURPOSE: To identify patients' attitudes toward the role of medical students, their preferences regarding medical student involvement, and their comfort level with a medical student's presence during common clinical situations in obstetrics-gynecology. METHOD: A self-administered questionnaire was distributed to patients waiting for an office visit with the obstetricians or gynecologists who served as preceptors for both male and female medical students. The questionnaire asked patients about their comfort levels with having medical students present during commonly encountered clinical situations. A random subsample of these patients were also asked whether they would allow a medical student to be present during future visits, and why or why not. RESULTS: A total of 229 patients completed the survey and 124 responded to the supplemental survey. Sixteen respondents were excluded due to missing data or a lack of an adequate comparison group. A majority responded they would feel comfortable having a medical student present during most clinical situations. Almost half of the patients preferred to see the doctor and medical student together, while less than a quarter wanted to see just the physician. Patients with more experience with medical students were more likely to favor medical student involvement and would feel more comfortable having a medical student present during obstetrics or gynecology clinical situations. CONCLUSION: Patients are willing to involve and feel comfortable with medical students in the obstetrics-gynecology clinic. However, physicians and clinics need to take steps to ensure that patient willingness and comfort are maintained by asking patients about their comfort with medical student involvement, clearly outlining the roles and responsibilities of participating medical students, and gradually increasing medical students' responsibilities as patients gain more experience with them.

Prevalence of SIDS risk factors: before and after the "Back to Sleep" campaign in North Dakota Caucasian and American Indian infants.

The objective of this study was to compare rates of infant sleeping position and other risk factors for sudden infant death syndrome from 1991 before the "Back to Sleep" campaign to rates in 1998 after the campaign. We used a cross-sectional risk factor prevalence study of risk factors for the years 1991 and 1998. In North Dakota the prevalence rates of prone sleeping declined 72% for American Indian infants and 62% for Caucasian infants. We were unable to identify a corresponding decline in SIDS in North Dakota for this time period. The relationship between sleeping position and SIDS may be more complex in rural and frontier settings and in American Indian populations than in urban and majority populations. The generalizability of this study is limited by the rural setting and small sample size. Longer term surveillance and additional reports from sites with pre "Back to Sleep" data as a baseline for both SIDS rates and sleeping position will be important to clarify the rate of prone sleeping position and SIDS.
