  • Background:  Tenofovir (TDF) is associated with renal phosphate wasting, elevation in markers of bone turnover, and decrease in bone density. Vitamin D3 (VITD) treatment increases renal tubular phosphate absorption in VITD deficiency. VITD deficiency/insufficiency (serum 25-OH VITD 80% of HIV+ youth in the U.S. We hypothesized that VITD administration would increase tubular reabsorption of phosphate (TRP) and decrease serum parathyroid hormone (PTH), bone alkaline phosphatase (BAP), and C telopeptide (CTX) in HIV+ youth treated with TDF.Methods:  Randomized controlled trial (RCT) of VITD 50,000 IU vs placebo (PL) every 4 weeks for 12 weeks (3 directly observed oral doses) in HIV+ youth ages 18 to 24, viral load <0.001 vs VITD). TRP did not change in either group. PTH decreased in the TDF group receiving VITD, but not in the no TDF group receiving VITD or the PL groups. Ca intake affected the strength of the VITD-TDF interaction. CTX and BAP did not change significantly with VITD. There were no clinical bone or renal toxicities or elevations of serum Ca above normal in either group.Conclusions:  Supplementation with VITD3 50,000 IU monthly for 12 weeks in HIV+ youth was safe and reduced VITD insufficiency by 46%. VITD was associated with a significant decrease in PTH in those on TDF-containing cART. There was no change in TRP, CTX, or BAP. The effect of VITD on PTH was seen only in those on TDF, suggesting a possible interaction between TDF, PTH, and VITD.
  • We also calculated the population attributable risk, which accounts for not only the strength of the association of a risk factor with mortality, but also for the prevalence of the condition in the population.We found that having arm muscle in the lowest tertile was associated with a population level risk of 15%. This represents the proportion of deaths over five years in an HIV-infected population that are expected due to having low arm muscle. As an absolute risk, this translates to two deaths per 100 HIV+ ppl expected over five years.For low leg muscle or high VAT, the population level risk was around 7%. This translates to an absolute risk of about 1 death per 100 HIV+ ppts over 5 years.

  • Methods to Detect AnalWarts, Cancer, and Dysplasia
  • Anal Cancer in HIV+ Men and Women Diagnosis and Treatment Pap-smears and simple anoscopy done in the office. Cytology obtained from pap smears. Outpatient under anesthesia: after high resolution anoscopy (HRA) with vinegar, any lesions are treated with infrared coagulation (IRC), which involves inserting a light probe into the anal canal under direct visualization, touching the tip of this light probe to the lesion, and delivering a pre-specified amount of energy. Trained Physicians by UCSF’s anal neoplasia and research group web site : http://www.analcancerinfo.ucsf.edu/

  • Exercise: The Best Medicine Benefits: total and abdominal fat improves insulin sensitivity improves glucose tolerance increases HDL cholesterol triglycerides and LDL increases muscle mass improves endurance improves strength improves bone density improves mood decreases frailty
  • EXERCISE FOR BEST RESULTS
  • Aerobic (Cardiovascular) Exercise Start with a brisk walk every day if tired Concentrate in low impact or no impact exercises (e.g. Elliptical Trainers) Do what you enjoy (bicycling, roller skating, etc) Good for burning fat, triglycerides, blood sugar, but it may decrease muscle mass 20 - 30 minutes 3-4 times a week is enough for many people Cardiovascular exercise may increase fat loss under the skin
  • Progressive Resistance Exercise (PRE) Warm up and stretch before a session Start with compounded exercises Lift maximum weight for muscular failure (exhaustion) at 8-12 repetitions One body part per week One hour sessions 3-4 times a week One light set and two heavier sets per body part If no access to a gym, start with crunches, push ups, and squats at home. Use stairs! For more details, visit www.medibolics.com
