Association of antiretroviral therapy with anal high-risk human papillomavirus, anal intraepithelial neoplasia, and anal cancer in people living with HIV: a systematic review and meta-analysis.

BACKGROUND: The effect of antiretroviral therapy (ART) on the natural history of anal high-risk HPV and anal lesion progression is not well established. We reviewed the association of ART and other HIV-related factors on anal HPV infection, anal intraepithelial neoplasia (AIN), and anal cancer among people living with HIV. METHODS: For this systematic review and meta-analysis, we searched MEDLINE and EMBASE for studies published between Jan 1, 1996, and Oct 30, 2019, that reported the association of HIV-related exposures (ART or highly active ART [HAART], HIV-RNA plasma viral load [PVL], and nadir or current CD4 cell count) with outcomes of anal high-risk HPV prevalence, incidence, and persistence; prevalence, incidence, progression, or regression of anal histological and cytological abnormalities; and anal cancer incidence. Effect estimates were extracted whenever available; otherwise, they were calculated from raw data. We assessed the risk of bias of included studies using the Newcastle-Ottawa scale, and random-effects meta-analyses were done to examine heterogeneity using the I2 statistic. This study is registered on the PROSPERO database, CRD42018007271. FINDINGS: We identified 6777 studies, of which 5377 were excluded before full-text review. 122 studies providing estimates for 130 distinct populations matched the inclusion criteria. The populations comprised 417 006 people living with HIV (women, men who have sex with men, and men who have sex with women). 41 (32%) population estimates were not stratified by sex or sexual orientation. People living with HIV receiving ART had 35% lower high-risk HPV prevalence than ART-naive people (crude odds ratio [OR] 0·65, 95% CI 0·54-0·79; I2 12·1%, p=0·31) in 18 studies, and prolonged ART use was associated with a 10% reduction per year in high-risk HPV prevalence in two studies (adjusted OR 0·90, 0·85-0·95; I2 0%, p=0·88). People living with HIV with undetectable PVL had lower HSIL-AIN2+ prevalence than those with detectable PVL (crude OR 0·84, 0·72-0·98; I2 0%, p=0·80) in 16 studies, particularly if sustained for more than 1 year (crude OR 0·62, 0·47-0·81; I2 0%, p=0·51). ART was not associated with anal cancer incidence when adjusted for years living with HIV in three studies (adjusted hazard ratio [HR] 1·11, 95% CI 0·68-1·80; I2 0%, p=0·57), but ART users with sustained undetectable HIV PVL had 44% lower risk of anal cancer than those without (adjusted HR 0·56, 0·44-0·70; I2 0%, p=0·94) and for each increase in nadir CD4 cell counts of 100 cells per µL, there was a 40% decrease in anal cancer incidence (crude HR 0·60, 0·46-0·78; I2 21·7%, p=0·26). INTERPRETATION: Effective ART use and early initiation at high nadir CD4 counts might reduce anal high-risk HPV infection and anal cancer risk. Although most studies were cross-sectional in design and few adjusted for potential confounders, this analysis provides comprehensive estimates of the effect of ART and HIV-related factors on the natural history of anal HPV-related disease in people living with HIV.

[Drug related problems and hospital admissions]. / Problemas relacionados con la medicación que causan ingresos hospitalarios.

OBJECTIVE: Drug related problems (DRP) are health problems associated with the pharmacological treatment of patients and interfere or can interfere with the expected results on their health. The aim of this study is to determine the prevalence of DRP in patients from an urban health centre that lead to hospitalisation, and its prevention. DESIGN: It is a retrospective, observational and descriptive study. SETTING: Les Corts Health Centre (HC), which is an urban health and teaching centre with a reference population of 32,318 inhabitants. PARTICIPANTS: Users of the les Corts HC admitted to the Barcelona Hospital Clinic from August 2005 to January 2006. RESULTS AND MAIN OUTCOME MEASUREMENTS: A pharmacist and a family doctor analysed the clinical histories and determined whether or not there was a DRP. A DRP was present in 13.4% of all hospital discharges, and 12% were implicated in the hospital admission. It was considered that 57.3% of all the discharges with a DRP as the causing factor in the hospital admission were avoidable. Admissions due to DRP were mainly in internal medicine, cardiology and pneumology. The health problems that lead to hospital admission due to DRP are mainly circulatory (38.5%) and respiratory (11.5%). CONCLUSIONS: The number of hospital admissions due to drug related problems is avoidably high.

[Osteopenia in primary health care patients: ¿do we need to be more rigorous?]. / Osteopenia en atención primaria: ¿debemos ser más rigurosos?

AIM: To describe the treatment prescribed to osteopenic women seen at an urban primary health care centre and the treatment compliance of those patients with a prescription of calcium and/or vitamin D. MATERIALS AND METHOD: Cross-sectional study, osteopenic women diagnosed by bone densitometry between February 2005 and January 2006 (n=121). Clinical history review: demographic information; previous clinical history of bone fracture, type of fracture; parental history of fractures; tobacco use; osteoporosis-related medication or disease; dietary and sun exposure assessment; calcium, vitamin D and raloxiphene/bisphosphonates prescription; mean daily dose of calcium and vitamin D supplements collected at the pharmacy by patients. Analysis of treatment prescription and compliance according to the information collected was performed. RESULTS: Mean age, 61.9±9.1 years; 90.7% post-menopausic. The dietary assessment was performed in 30.5% of the women included in the study. The drug prescription was as follows: calcium 74.6%, vitamin D 68.6% and raloxiphene/bisphosphonates 16.1%. All drug prescriptions were associated with lower T-score values. The patient's compliance of calcium supplements has been calculated as mean of 423.8±321.7 mg/day, and 343.1±225.9 IU of vitamin D; with no association with any of the studied variables. CONCLUSIONS: We identified greater drug prescription in those patients with a lower T-score. The clinical history of previous fracture did not show association with drug prescription nor a better compliance. There was a lack of information about relevant issues in the clinical history of the osteopenic women included in the study. The patient's compliance of calcium and vitamin-D supplements is very variable.

Prospective, randomised study on antibiotic prophylaxis in colorectal surgery. Is it really necessary to use oral antibiotics?

BACKGROUND AND AIMS: The use of prophylactic antibiotics in addition to mechanical cleansing is the current standard of care prior to colonic surgery. The question of whether the antibiotics should be administered intravenously or orally, or by both routes, remains controversial. Our aim was to compare three methods of prophylactic antibiotic administration in elective colorectal surgery. METHODS: Three hundred consecutive elective colorectal resections were studied. All patients had preoperative mechanical colon cleansing with oral sodium phosphate and intravenous antibiotic prophylaxis with cefoxitin (one dose before skin incision and two postoperative doses). Patients were randomised to one of the following three groups: group A: three doses of oral antibiotic (neomycin and metronidazole) at the time of mechanical colon cleansing; group B: one dose of oral antibiotic; group C: no oral antibiotics. All patients were followed during their hospital stay and at 7, 14 and 30 days post-surgery. RESULTS: Vomiting occurred in 31%, 11% and 9% of the studied patients (groups A, B and C, respectively) (p<0.001). Nausea was present in 44%, 18% and 13% of patients (p<0.001). Abdominal pain was recorded in 13%, 10% and 4% of patients (p: 0.077). Wound infection was present in 7%, 8% and 6% and suture dehiscence occurred in 2%, 2% and 3% of the patients in the three groups (no differences among them). Neither were differences found among the three groups in terms of urinary infections, pneumonia, postoperative ileus or intra-abdominal abscess. CONCLUSION: The addition of three doses of oral antibiotics to intravenous antibiotic prophylaxis is associated with lower patient tolerance in terms of increased nausea, vomiting and abdominal pain, and has shown no advantages in the prevention of postoperative septic complications. Therefore, we recommend that oral antibiotics should not be used prior to colorectal surgery.

[Risk of Suffering from Cardiovascular Diseases because of the Clustering of the Modifiable Cardiovascular Risk Factors in the Population Older than 15 years of a Health Care Center in Barcelona]. / riesgo de presentación de eventos cardiovasculares según la agrupación de los factores de riesgo modificables en la población mayor de 15 de años de un centro de salud de barcelona.

OBJECTIVE: Over recent decades, the death rate due to cardiovascular diseases has shown a downward trend in developed countries, as has also been the case in Spain. However, are still the leading cause of death. This study is aimed at studying the relationship between cardiovascular diseases and different modifiable cardiovascular risk factors related to their clustering. METHODS: Descriptive cross-sectional study conducted at an urban healthcare center, which included 2248 individuals ages 15 and above selected by simple random sampling of the medical record files. The risk of having some cardiovascular disease (ischemic cardiopathy, cerebrovascular disease or peripheral arteriopathy of lower limbs) was calculated in the form of an odds ration (OR) in relation to the clustering of the risk factors of smoking, high blood pressure,hypercholesterolemia, hypertriglyceridemia and diabetes mellitus,adjusted by age, sex and risk factors. RESULTS: The individuals studied had 224 cardiovascular diseases.For smoking, the OR as an isolated risk factor was 1.5 (95% CI:1.0-2.2) and 1.6 (95% CI: 0.9-2.5) with the clustering with the other four risk factors; with high blood pressure, respectively of 2.1 (95% CI: 1.5-2.9) and 1.7 (95% CI: 1.1-2.6); with hypercholesterolemia, respectively of 1.7 (95% CI: 1.2-2.4) and 1.6 (95% CI: 1.1-2.4); and with hypertriglyceridemia, respectively of 1.8(95% CI: 1.2-2.8) and 1.3 (95% CI: 0.8-2.1). The OR's showed a similar behavior on layering by each cardiovascular disease, although the highest OR's (2.4 - 3.1 range) corresponded to the clustering of diabetes mellitus and smoking. CONCLUSIONS: The risk of having cardiovascular diseasesremains high with the clustering of cardiovascular risk factors,although differences among them are found to exist.

OBJETIVO: En la últimas décadas la mortalidad por enfermedades cardiovasculares ha mostrado una tendencia decreciente en los países desarrollados, confirmada asimismo en España. No obstante siguen siendo la principal causa de mortalidad El objetivo de este trabajo es estudiar la asociación entre las enfermedades cardiovasculares y diversos factores de riesgo cardiovascular modificables en relación a su agrupación (clustering). METODOS: Estudio descriptivo transversal realizado en un centro de salud urbano, que incluyó a 2.248 personas de 15 o más años, seleccionadas por muestreo aleatorio simple del archivo de historias clínicas. Se calculó en forma de odds ratio (OR) el riesgo de tener alguna enfermedad cardiovascular (cardiopatía isquémica, enfermedad cerebrovascular o arteriopatia periférica de extremidades inferiores)en relación al clustering de los factores de riesgo tabaquismo,hipertensión arterial, hipercolesterolemia, hipertrigliceridemia y diabetes mellitus, ajustado por edad, sexo y factores de riesgo. RESULTADOS: Las personas estudiadas tenían 224 enfermedades cardiovasculares. En el tabaquismo la OR como factor de riesgo aislado fue de 1,5 (IC95%: 1,0-2,2) y de 1,6 (IC95%: 0,9-2,5) con el clustering con los otros 4 factores de riesgo; con la hipertensión arterial de 2,1 (IC95%: 1,5-2,9) y de 1,7 (IC95%: 1,1-2,6), respectivamente; con la hipercolesterolemia de 1,7 (IC95%: 1,2-2,4) y de 1,6 (IC95%: 1,1-2,4), respectivamente; con la diabetes de 2,5 (IC95%: 1,7-3,5) y 2,0 (IC95%: 1,3-3,0), respectivamente y con la hipertrigliceridemia de 1,8 (IC95%: 1,2-2,8) y 1,3 (IC95%: 0,8-2,1), respectivamente. Las OR se comportaron de manera similar al estratificar por cada enfermedad cardiovascular, aunque las OR más elevadas (entre 2,4 y 3,1) correspondieron al clustering de diabetes mellitus y tabaquismo. CONCLUSIONES: El riesgo de tener enfermedades cardiovasculares sigue siendo elevado con el clustering de factores de riesgo cardiovascular,aunque se observan diferencias entre ellos.
