Integrated preventive care coverage effectiveness in high-risk worksites in Mexico

Objectives  

Worksites have been considered a propitious environment for promoting health. In 2005, an integrated preventive care (IPC) system was implemented in Mexico consisting of health promotion and disease prevention interrelated activities, delivered on a single visit and on location. This project contributes relevant information on IPC coverage and its degree of effectiveness on providing health promotion services to workers at high-risk worksites.     

Reduction of functional deterioration during hospitalization in an acute geriatric unit

The purpose of this study was to compare the incidence of functional deterioration of elderly patients hospitalized in acute care geriatric units compared to that in a conventional care unit. We performed a prospective controlled study over 9 months of patients above 65 years old with acute medical pathology. Upon discharge, we compared the degree of functional deterioration using the Katz index compared to the basal level before admission of both groups. Of the 143 patients studied, 68 were admitted to the geriatric care unit and 75 to the conventional care unit. In the geriatric unit, the incidence of functional deterioration occurred in 13 patients (19.1%), while in the conventional care unit it occurred in 30 (40%) (p=0.01). In a multivariate analysis of logistical regression, the odds ratio of developing functional deterioration at discharge in the conventional care unit, compared to the geriatric unit was 4.24 (95% CI: 1.50-11.99). The length of stay was shorter in the geriatric unit (7.5 vs. 9.92, p=0.03). We conclude that the elderly patients admitted to a geriatric care unit showed less functional deterioration on discharge compared with those kept in another care unit of a conventional type.     

Risk of contrast-induced nephropathy in hospitalized patients with cirrhosis

AIM： TO evaluate the incidence of contrast-induced nephropathy （CIN） in cirrhotic patients and to identify risk factors for the development of CIN.
METHODS： We performed a retrospective review of 216 consecutive patients with cirrhosis who underwent computed tomography （CT） with intravenous contrast at the University of Rochester between the years 2000-2005. We retrospectively examined factors associated with a high risk for CIN, defined as a decrease in creatinine clearance of 25% or greater within one week after receiving contrast.
RESULTS： Twenty-five percent of our patients developed CIN, and 74% of these patients had ascites seen on CT. Of the 75% of patients who did not develop CIN, only 46% had ascites. The presence of ascites was a significant risk factor for the development of CIN （P = 0.0009, OR 3.38, 95% CI 1.55-7.34） in multivariate analysis. Patient age, serum sodium, Model for End-stage Liver Disease score, diuretic use, and the presence of diabetes were not found to be significant risk factors for the development of CIN. Of the patients who developed CIN, 11% developed chronic renal insufficiency, defined as a creatinine clearance less than baseline for 6 wk.
CONCLUSION： Our results suggest that in hospitalized cirrhotic patients, especially those with ascites, the risk of CIN is substantial.     

Percutaneous alcohol septal ablation for hypertrophic obstructive cardiomyopathy: technical review and long-term clinical and echocardiographic outcomes

BackgroundPercutaneous septal ablation by alcohol-induced septal branch occlusion was introduced as a new treatment option in symptomatic patients with hypertrophic obstructive cardiomyopathy (HOCM). Our aim was to evaluate procedural and long-term clinical and echocardiographic outcomes in patients with HOCM treated by alcohol septal ablation (ASA) at our center.MethodsThis single-center retrospective study included 14 consecutive HOCM patients undergoing percutaneous ASA (66.4 ± 12.1 years, 71.4% female). At baseline all patients presented persistent symptoms despite optimized medical treatment, left ventricular outflow tract (LVOT) obstruction with a peak gradient >50 mmHg, systolic anterior motion of the mitral valve, and ventricular septal thickness ≥15 mm. ASA was considered successful when the LVOT pressure gradient fell to less than 50% of baseline value. All patients had echocardiographic evaluation at baseline, intraprocedure and at follow-up, and a long-term clinical follow-up (25 ± 38 months) with evaluation of functional class and occurrence of symptoms or cardiovascular events.ResultsPercutaneous ASA achieved a 71.4% acute and 85.7% long-term success rate. Peak LVOT gradient decreased from 104 ± 40 mmHg at baseline to 58 ± 30 mmHg intraprocedure (p = 0.03) and 35 ± 26 mmHg at follow-up (p = 0.001); total gradient decrease was 75 ± 43 mmHg. Ventricular septal thickness and mitral regurgitation also presented significant decreases during follow-up (from 24 ± 5 mm to 18 ± 4 mm, p = 0.02, and from grade 2.4 ± 0.6 to 1.4 ± 0.5, p < 0.001, respectively). A tendency for long-term improvement in NYHA functional class (from 2.6 ± 1.1 to 1.8 ± 1.4, p = 0.09) was observed. Procedural complications occurred in 6.7% of patients; two deaths and one transient ischemic attack occurred in-hospital, but no long-term clinical events were recorded.ConclusionsPercutaneous ASA is an effective treatment for symptomatic patients with HOCM, obtaining a marked decrease in LVOT pressure gradient and symptomatic improvement. Despite the occurrence of a significant number of procedural complications, the favorable long-term outcomes underline the potential of ASA as a percutaneous alternative to surgical myectomy.     

Patterns and Predictors of Multiple Sexual Partnerships Among Newly Arrived Latino Migrant Men

Multiple sexual partnerships (MSP), both concurrent and serial short gap, are thought to increase the risk of HIV and sexually transmitted infection (STI) acquisition and transmission. In this study we evaluate potential individual and environmental risk factors for engaging in MSP in a cohort of newly arrived Latino migrant men (LMM) in New Orleans, LA, USA. Participants were surveyed at three time points over a nine-month period to examine factors associated with MSP. Of the 113 men, 32.5 % reported ever MSP. In 290 observations, 19.5 % of men had concurrent, and 15.0 % had serial short gap partnerships in at least one interviews. Substance was associated with MSP, OR (95 % CI) 2.00 (1.16, 3.45) whereas belonging to a community organization was found to be protective, OR 0.32 (0.17, 0.59). Interventions to reduce substance use and promote social connection are needed to prevent a potential HIV/STI epidemic in this population.     

Does preoperative total parenteral nutrition in patients with ulcerative colitis produce better outcomes?

Purpose

Malnutrition is a frequent problem in patients with ulcerative colitis (UC) leading to increased postoperative complication rates. Preoperative total parenteral nutrition (TPN) has been shown to reduce complications in some subgroups of patients, but has not been studied in UC. We investigated the impact of preoperative TPN on postoperative complication rates in patients undergoing surgery for UC.

Methods

This paper is a review of 235 patients who underwent surgery for UC; 56 received preoperative TPN and 179 did not. Postoperative complication rates were compared.

Results

Both had similar rates of anastomotic leak (5.4 vs. 2.8?%, p?=?0.356), infection (12.5 vs. 20.1?%, p?=?0.199), ileus/bowel obstruction (21.4 vs. 15.6?%, p?=?0.315), cardiac complications (3.6 vs. 0?%, p?=?0.056), wound dehiscence (3.6 vs. 1.7?%, p?=?0.595), reoperation (10.7 vs. 3.9?%, p?=?0.086), and death (1.8 vs. 0?%, p?=?0.238). The TPN group was more malnourished (albumin 2.49 vs. 3.45, p?<?0.001), more often on steroids (83.9 vs. 57.5?%, p?<?0.001), had more emergent surgery (10.7 vs. 3.4?%, p?=?0.029), more severe colitis (89.3 vs. 65.9?%, p?=?0.001), and lower Surgical Apgar Score (6.15 vs. 6.57, p?=?0.033). After controlling for these with logistic regression, the TPN group still had higher complication rates (OR 2.32, p?=?0.04). When line infections were excluded, TPN did not significantly affect outcomes (OR 1.5, p?=?0.311)

Conclusion

There were no differences in postoperative complications when line infections were excluded. Our data does not support routine preoperative TPN in patients with UC. However, it may lead to equal surgical outcomes in the sickest and most malnourished patients at the cost of line-related morbidity.     

Patterns and Predictors of HIV/STI Risk Among Latino Migrant Men in a New Receiving Community

The purpose of this study was to examine patterns and predictors of HIV/STI risk over time among Latino migrant men in a new receiving community. Latino men (N = 125) were interviewed quarterly for 18 months and HIV/STI tested annually. Selected individual, environmental and cultural factors by partner type and condom use were explored longitudinally and in a cross-section. Sex with female sex workers (FSWs) and multiple partners decreased, sex with main partners and abstinence increased, while the number of casual partners remained stable. Consistent condom use was highest with FSWs, lowest with main partners and midrange with casual partners with no trends over time. STI morbidity was low; no HIV was detected. Drug use and high mobility were associated with inconsistent condom use with FSW, whereas having family in the household was protective. HIV/STI prevention efforts should focus on drug using Latino migrants who are highly mobile and should foster healthy social connections.
