Precocious mammary development in an 8-month-old Holstein heifer.

An 8-month-old, virgin Holstein heifer with precocious mammary development was presented for examination. Protein, fat, and lactose in the mammary secretion were 14.90%, 0.12%, and 0.20%, respectively; somatic cell count was 3.9 x 10(6)/mL, with no bacterial infection. The heifer was inseminated at 15 months of age, confirmed pregnant, and subsequently slaughtered.

Gene expression profiling of dysplastic differentiation in cervical epithelial cells harboring human papillomavirus 16.

Molecular events occurring with high-risk human papillomavirus (HPV)-associated dysplastic differentiation of cervical epithelial cells are largely unknown. This study used differential display PCR to identify expression changes between nondifferentiating monolayer and differentiated organotypic (raft) cultures of W12 keratinocytes. These cells were originally derived from a clinical biopsy of HPV 16-positive dysplastic cervical epithelium and retain high-risk HPV 16 and the ability to differentiate, albeit with dysplastic morphology. Using this model system we identified 84 genes with changed expression during dysplastic differentiation. Most (70/84, approximately 80%) were down-regulated with differentiation, consistent with a restriction of expression during terminal differentiation. Twenty-two genes had no known function and 6 novel expressed sequence tags were identified among this group. Of the 62 genes with known functions, 25 belonged to transcription-, translation-, and posttranslation-related categories and 30 had functions associated with neoplastic initiation/progression, calcium signaling, epithelial differentiation, and structure remodeling. Some of the genes with altered expression identified in this model of dysplastic differentiation may be useful biomarkers for early detection of cervical neoplasia and other HPV-associated oropharyngeal and anogenital cancers.

Audit of a shared-care program for persons with diabetes: baseline and 3 annual follow-ups.

In Italy, data on shared-care programs for diabetes are lacking. We described the characteristics of type 2 diabetic population assisted in general practice and evaluated 3 years of follow-up outcomes and performance indicators in a shared-care program in Modena, Italy (1998-2001); only well-controlled diabetic patients were considered. Forty-nine percent of territorial GPs adhered to the project (257 out of 521) and 77% of them sent 6409 paired baseline and follow-up datasheets. Altogether, 97.8% patients had type 2 diabetes, mean age 68.6+/-11.7 years, disease duration 9.6+/-7.5 years, BMI 28.6+/-4.8 kg/m2, HbA(1c) 7.6%+/-1.6%, 16.1% of them were disabled. Among the non-disabled patients, 23.6% had optimal glycemic control (HbA(1c) < or =6.5%); at baseline the prevalence of micro- and macrovascular diabetic complications was: 8.2% microalbuminuria and 2.4% macroalbuminuria plus nephropathy, 11.0% nonproliferative and 3.0% preproliferative retinopathy, 7.0% neuropathy, 1.8% diabetic foot; 8.5% angina, 6.9% TIA or stroke, 6.3% infarction, 5.2% intermittent claudication, 4.1% heart failure. Among the disabled patients 27.9% had optimal glycemic control, but they had more diabetic complications. The performance indicators significantly improved over the 3-year study period: glycemic control indicators increased from 66%-75% to 83%-90% and micro- and macrovascular indicators from 59%-65% to 75%-81%. The outcome indicators also improved: mean HbA(1c) value changed from 7.6%+/-1.6% to 7.3%+/-1.3% and the percentage of people with HbA(1c)< or =6.5% significantly improved over time. Similar trends were observed in both disabled and non-disabled diabetic patients.

Changes in long-term glycemic control and performance indicators in a cohort of type 2 diabetic patients cared for by general practitioners: findings from the "Modena Diabetes Project".

BACKGROUND AND AIM: General practitioners (GPs) are being increasingly asked to play a key role in the shared care of people with diabetes mellitus, but data concerning the effects of this in Italy are still scarce. We therefore evaluated the 4-year follow-up changes in outcomes and performance indicators in type 2 diabetic patients cared for by GPs in the framework of the "Modena Diabetes Project". METHODS AND RESULTS: Seventy-four percent of the local GPs participating in the project (387 out of 521) sent 5260 paired baseline and follow-up datasheets. The baseline characteristics of the type 2 diabetic patients (49.6% male) were a mean age of 67.3+/-11.2 years, a mean disease duration of 10.9+/-7.4 years, a mean BMI of 28.7+/-4.8 kg/m2, and a mean HbA1c level 7.56+/-1.52%. After four years follow-up, the individual before/after match-paired outcomes revealed an improvement in glycemic control: HbA1c levels significantly decreased to 7.39+/-1.31%, and the percentage of patients with HbA1c level of <6.5% significantly increased from 15.7% to 22.1%. There was also a significant decrease in body weight (from 78.3+/-14.8 to 77.6+/-14.6 kg) and BMI (from 28.8+/-4.8 to 28.5+/-4.9 kg/m2). The time trends of glycemic control significantly improved during the 4-year follow up, but those of the body weight and BMI values did not. Furthermore, the percentages of performance indicators matching the expected rate of recurrence per each year of follow-up significantly improved during the study period. CONCLUSIONS: Long-term glycemic control and the performance indicators relating to the type 2 diabetic patients participating in our shared care programme progressively improved.
