RESUMO

The aim of this paper is to describe the protocol of a study assessing the impact of a Community-based pro-Active Monitoring Program, by measuring the effect in counteracting the adverse outcomes related to frailty. METHODS: a prospective pragmatic trial will be carried out to describe the impact of an intervention on people aged>80, adjusted for relevant parameters: demographic variables, comorbidities, disability and bio-psycho-social frailty. They have been assessed with the Functional Geriatric Evaluation questionnaire that is a validated tool. Mortality, Acute Hospital Admission rates, Emergency Room Visit rates and Institutionalization rates are the main outcomes to be evaluated annually, over three years. Two groups of patients, made up by 578 cases (undergoing the intervention under study) and 607 controls have been enrolled and interviewed. RESULTS: at baseline the two groups are quite similar for age, living arrangement, comorbidity, disability and cognitive status. They differ in education, economic resources and physical status (that are better in the control group) and in social resources (that is better in the case group). The latter was expected since the intervention is focused on increasing social capital at individual and community level and aimed at improving survival among the cases as well as reducing the recourse to hospital and residential Long Term Care. CONCLUSION: The proposed study addresses a crucial issue: assessing the impact of a bottom up care service consisting of social and health interventions aimed at reducing social isolation and improving access to health care services.

RESUMO

BACKGROUND: Tuberculosis (TB) represents the ninth leading cause of death worldwide. In 2016 are estimated 1.3 million TB deaths among HIV negative people and an additional 374,000 deaths among HIV positive people. In 2016 are estimated 1.4 million new cases of TB in people living with HIV (PLHIV), 74% of whom were living in Africa. In light of these data, the reduction of mortality caused by TB in PLHIV is strongly required specially in low-income countries as Mozambique. According to international guidelines, the initial TB screening in HIV+ patients should be done with the four symptoms screening (4SS: fever, current cough, night sweats and weight loss). The diagnostic test more used in resource-limited countries is smear microscopy (SMEAR). World Health Organization (WHO) recommended Lateral Flow urine LipoArabinoMannan assay (LF-LAM) in immunocompromised patients; in 2010 WHO endorsed the use of Xpert Mycobacterium Tuberculosis/Rifampicin (MTB/RIF) test for rapid TB diagnosis but the assay is not used as screening test in all HIV+ patients irrespectively of symptoms due to cost and logistical barriers. The paper aims to evaluate the cost-effectiveness of three screening protocols: standard (4SS and SMEAR in positive patients to 4SS); MTB/RIF; LF-LAM / MTB/RIF. METHODS: We developed a model to assess the cost-effectiveness of the MTB/RIF protocol versus the common standard and LF-LAM / MTB/RIF protocol. The model considered a sample of 1,000 HIV+ antiretroviral treatment naïve patients in Mozambique. We evaluated disability-adjusted life year (DALY) averted for each protocol, cost per DALY, and incremental cost-effectiveness ratio (ICER), over 1-year, assuming a national healthcare system perspective. The model considered the delayed diagnosis as the time elapsed between a false negative test and the diagnosis and treatment of TB. Additional health system organization delay is defined as the time interval between positive test and treatment initiation caused by a delay in the delivery of results due organization of services. We conducted a sensitivity analysis on more relevant variables. RESULTS: The MTB/RIF protocol was cost-effective as compared to the standard protocol with an ICER of $56.54 per DALY saved. In a cohort of 1,000 patients MTB/RIF and LF-LAM / MTB/RIF protocol generated 1,281 and 1,254 DALY's saved respectively, with a difference of 174 and 147 DALY respect to the standard protocol. The total cost of MTB/RIF protocol was lower ($92,263) than the standard ($147,226) and the LF-LAM / MTB/RIF ($113,196). Therefore, the cost per DALY saved including new infections due to delayed diagnosis with the standard protocol was $79.06, about 5 fold higher than MTB/RIF and LF-LAM / MTB/RIF protocols. The cost of additional TB infections due to delays in diagnosis plus health system delay seemed the more relevant costs. The low sensibility and sensitivity of the standard protocol led to a high number of false negatives, thus delayed TB diagnoses and treatment lead to the development of newly transmitted TB infections. CONCLUSIONS: Our study shows that the MTB/RIF adoption could lead to an increasing of TB case-finding and a reduction in costs compared with standard and LF-LAM / MTB/RIF protocols.

RESUMO

OBJECTIVES: Retention of subjects in HIV treatment programmes is crucial for the success of treatment. We evaluated retention/loss to follow-up (LTFU) in subjects receiving established care in Malawi. METHODS: Data for HIV-positive patients registered in Drug Resource Enhancement Against AIDS and Malnutrition centres in Malawi prior to 2014 were reviewed. Visits entailing HIV testing/counselling, laboratory evaluations, nutritional evaluation/supplementation, community support, peer education, and antiretroviral (ART) monitoring/pharmacy were noted. LTFU was defined as > 90 days without an encounter. Parameters potentially associated with LTFU were explored, with univariate/multivariate logistic regression analyses being performed. RESULTS: Fifteen thousand and ninety-nine patients registered before 2014; 202 (1.3%) were lost to follow-up (LTFU) (1.3%). Nine (0.5%) of 1744 paediatric patients were LTFU vs. 1.4% (n = 193) of 13 355 adults (P < 0.001). Subjects who were LTFU had fewer days in care than retained subjects (1338 vs. 1544, respectively; P < 0.001) and a longer duration of ART (1530 vs. 1300 days, respectively; P < 0.001). Subjects who were LTFU had higher baseline HIV viral loads (P = 0.016) and higher body mass indexes (P < 0.001), were more likely to live in urban settings (88% of patients who were LTFU lived in urban settings) with better housing [relative risk (RR) 2.3; 95% confidence interval (CI) 1.67-3.09; P < 0.001], and were more likely to be educated (RR 1.88; 95% CI 1.42-2.50; P < 0.001). Distance to the centre and cost of transportation were associated with LTFU (RR 3.4; 95% CI 2.84-5.37; P < 0.001), as was absence of a maternal figure (RR 1.57; 95% CI 1.17-2.09; P < 0.001). Viral load, distance index, education and a maternal figure were predictive of LTFU. CONCLUSIONS: Educated, urbanized HIV-infected adults living far from programme centres are at high risk of LTFU, particularly if there is no maternal figure in the household. These variables must be taken into consideration when developing retention strategies.

RESUMO

BACKGROUND: The population over 64 years of age is the main user of acute hospital care services. The elderly admission rates represent a marker for the appropriateness of the model of care. The aim of this study was to assess trends and determinants of acute in-patient care among the elderly in Italy between 2001 and 2011. STUDY DESIGN: Retrospective analysis of data included in the Italian Hospital Discharge Form Database. METHODS: Data from the Italian Hospital Discharge Form Database, Italian Ministry of Health, for the years 2001, 2006 and 2011 were analyzed for individuals over 64 years of age. Inpatient admission (> 1 day) rates across Italian Regions were calculated and compared with demographic variables and out-of-hospital care indicators. Univariate and multivariate analysis were used to determine independent relationship among variables. RESULTS: From 2001 to 2011 the elderly hospital admission rate decreased from 302.1/1,000 in 2001, to 222.4 in 2011, accounting for an overall decrease of about 28%. The decline in admission rates was less pronounced among individuals > 74 y (26.4%) than among those 65-74 y (32.1%). Hospitalization rates decreased in all Italian administrative regions between 2001 and 2011, even if the hospitalization rates in 2011 were still very different through the different Italian regions, ranging from 180.3/1,000 in Piedmont to 278.1/1,000 in Molise for people > 64 y. The multivariate linear regression was statistically significant in explaining the variations in hospitalization rates among the different Italian administrative regions (F: 3.637; p = 0.024; adjusted R2 = 0.57) and pointed to the role played by the proportion of the elderly (as percentage of the total population, p=0.043) and the rate of variation of acute care beds from 2004 to 2011 (p=0.001). Variables related to community-based care did not show any association with the hospital admissions rate among the elderly. CONCLUSIONS: The trend toward decline in elderly inpatient admissions is still present in 2011 as it was in 2001. Determinants of elderly hospital care in Italy are related to the increased number of elderly individuals and the reduction of hospital beds. Out-of-hospital care does not correlate with the variation of in-patient care so the overall care appropriateness could be negatively affected.

RESUMO

Mathematical modelling is an important tool for understanding the dynamics of the spread of infectious diseases, which could be the result of a natural outbreak or of the intentional release of pathogenic biological agents. Decision makers and policymakers responsible for strategies to contain disease, prevent epidemics and fight possible bioterrorism attacks, need accurate computational tools, based on mathematical modelling, for preventing or even managing these complex situations. In this article, we tested the validity, and demonstrate the reliability, of an open-source software, the Spatio-Temporal Epidemiological Modeler (STEM), designed to help scientists and public health officials to evaluate and create models of emerging infectious diseases, analysing three real cases of Ebola haemorrhagic fever (EHF) outbreaks: Uganda (2000), Gabon (2001) and Guinea (2014). We discuss the cases analysed through the simulation results obtained with STEM in order to demonstrate the capability of this software in helping decision makers plan interventions in case of biological emergencies.

RESUMO

The study included 309 HIV-infected pregnant women receiving a lamivudine-containing antiretroviral regimen from week 25 of gestational age until 6 months postpartum, during breastfeeding. Twenty-seven of them (8.7%) were hepatitis B virus surface antigen (HBsAg) positive; at baseline, hepatitis B virus (HBV) DNA levels >3 log(10) IU/mL (with a median level of 6.2 log(10) IU/mL) were found in 10 women, who at one, three and six months postpartum had median levels of 5.2 log(10) IU/mL, 4.5 log(10) IU/mL and 2.8 log(10) IU/mL, respectively. Twenty-four of the 30 breast milk samples evaluated had undetectable HBV DNA and the other six had values between 15 and 155 IU/mL. Median lamivudine concentrations were 1070 ng/mL in serum and 684 ng/mL in breast milk. Among the 24 HBV-exposed children with available samples, 16 always tested negative, four had a transient infection, one had an undetermined status and three (12.5%) first tested positive at Month 12 or Month 24. Among the children born to the HBV-uninfected mothers of the same cohort, the rate of HBsAg positivity at 12-24 months was 2% (4/196). Our finding of the absence of significative levels of HBV DNA in the breast milk of co-infected mothers supports the present recommendations for breastfeeding in HBV-infected women. Horizontal transmission can be hypothesized for the infections detected in children at 12-24 months. Children born to HBV-positive mothers remained at higher risk of postnatal HBV acquisition compared to those born to HBV-negative women.

RESUMO

AIM: Currently children of immigrants are the fastest growing segment of the Italian population under the age of 18. The present study reports the challenges to health services access, the vaccination coverage, the health and nutritional status of a sample of 1310 children of immigrants attended from February 2004 to May 2012 the health center "Medicina Solidale" of the "Policlinico Tor Vergata" in the suburban area of the VIII Municipality of Rome. METHODS: The data were collected using clinical archives of the health center. We analyzed the socio-demographic conditions, health problems and nutritional status on admission to the health center. The anthropometric evaluation was carried out according to international standards of child growth WHO 2006 and the statistical analysis was performed using SPSS version 19, and including risk estimation, Mantel Haentzel statistics and t-test. RESULTS: Sixty-six percent of the children were born in Italy, 62% had never had regular health care and 3.4% of children older than six months had never received any of the immunizations. It has been estimated that being Roma the risk of not been vaccinated is equal to OR=5.4 (IC95%: 2.8-10.1). Seventy-seven percent of unvaccinated children had at least one illiterate parent. This condition was strongly associated with non-immunization (OR=15:36 [IC95%: 6.4-36.4]). Growth retardation was common in Roma children as compared to other ethnicities. CONCLUSION: Significant public health efforts are needed to improve access to health services for immigrant populations and to solve relevant inequalities.

RESUMO

The continous health expenditure increase in developed countries is often related with the acute hospital care of the elderly. To monitor the characteristics of elderly acute hospital care included the expenditure trend is crucial in order to identify the appropriateness of this care. The aim of this study is to describe quality and quantity of in-hospital care use of elderly population in Italy in 2006 and to compare the results with the same information gathered for 1996 and 2001. All the 2006 acute hospital admission longer than one day of the patients older than 64 years sourced from the Register of Discharge Form of the Italian Ministry of Health have been analyzed. A list of the 30 more frequent diagnoses has been compiled and compared with the same list compiled for 2001. On the basis of the National Fee for each Disease Related Group an analysis of the hospital expenditure has been carried out. The correlation between DRGs National Fees and frequency of the diagnosis in the discharge form has been based on the 80 diagnosis that has been recorded for more than 10.000 discharge forms in 2006. A relevant increase of acute hospital admission for respiratory, cardiovascular and urinary pathologies among the elderly has been observed. Moreover the number of hospital admissions for major joints and implant of lower limbs is doubled from 1996. The total health expenditure for the elderly acute care longer than one day is increased of 6.3% and a positive correlation between higher DRGs fees and higher frequency of diagnosis has been observed (Pearson correlation value = 0.478; p<0.001 - cubic regression R-square value = 0.301; p<0.001). The hospital acute care use of the elderly patients seems to be more related to emergency care than in the past, while a decrease of DRGs related to chronic diseases and generic diagnosis has been observed. The more frequent cause of in-hospital admission seems to be related also to a higher DRGs fee. As already observed in the past years, a trend towards the use of more expensive DRGs could be detected.

RESUMO

PURPOSE: The aim of this paper is to report on the implementation of new guidelines on the use of injectable iodinated contrast media (ICM) at our workplace and specific protocols for the preparation of patients at risk. MATERIALS AND METHODS: Operators received training with continuing medical education (CME) credits. The new documentation (patient history/screening form and informed consent form) is available on the hospital Web site and requests serum creatinine determination with estimation of glomerular filtration rate (GFR) for every patient. Additional tests are required for high-risk patients only. RESULTS: Attendance rates were 57.2% among referring physicians and 74.5% among Radiology Department personnel. The Cockcroft-Gault formula was used to estimate GFR in adults. The main problem encountered in the implementation process was that referring physicians failed to evaluate the GFR in 80% of patients, with low GFR being discovered in the Radiology Department on the day of examination in 20% of patients, resulting in a need to reschedule the examination. CONCLUSIONS: Although not an easy task, implementation of the new guidelines for ICM use is both feasible and necessary. An additional refresher training course for personnel and GFR evaluation of the patient on referral are indispensable to ensure proper preparation of patients at increased risk of adverse reactions to ICM.

RESUMO

This study evaluates the effectiveness of a holistic model for treating people living with AIDS in Africa; the model aims to improve knowledge about AIDS prevention and care, increase trust in the health centre, impact behaviour, and promote a high level of adherence to HAART. The study took place in the context of the DREAM (Drug Resource Enhancement against AIDS and Malnutrition) programme in Mozambique, designed by the Community of Sant'Egidio to treat HIV patients in Africa. It provides patients with free anti-retroviral drugs, laboratory tests (including viral load), home care and nutritional support. This is a prospective study involving 531 patients over a 12-month period. The patients, predominantly poor and with a low level of education, demonstrated a good level of knowledge about AIDS (more than 90% know how it is transmitted) and trust in the treatment, with a relatively small percentage turning to traditional healers. Overall the patients had a low level of engaging in risky sexual behaviour and a very good level of adherence to HAART (69.5% of the 531 subjects had a pill count higher than 95%). The positive results of the programme's educational initiatives were confirmed with the patients' good clinical results.

RESUMO

Availability of Highly Active Anti-Retroviral Treatment (HAART) has modified the natural history of HIV infection, resulting in increase of seropositive subjects survival. The aim of the study was to assess patients' survival in relation to socio-economic status in HAART era using Functional Multidimensional Evaluation questionnaire. A three-level Socio-Economic Index (SEI) combining results from self-perception of unmet needs and objective data from the assessment of the two dimensions has been set up by the authors. Of the 382 subjects interviewed, 102 had been lost to follow-up. SEI showed that 66.4% of the sample faced unmet social or economic needs and 17.1% had unmet needs in both areas. There was a significant relationship between the self-sufficiency in performing Activities of Daily Living (ADL), Clinical Staging, CD4 cell count, SEI and risk of death. The lowest level of SEI was associated with a doubled risk of death compared to SEI upper level. Availability of social and economics support have a positive effect upon survival in patients with HIV infection, also in case of availability of HAART. The combination of subjective and objective assessment of socio-economic resources allows a better understanding of their impact on survival.

RESUMO

OBJECTIVE: To assess the incidence and consequences of adverse reactions among African HIV-positive pregnant women treated with fixed-dose combinations of a nevirapine-containing antiretroviral (ARV) triple therapy. METHODS: A retrospective analysis of the clinical files of 703 HIV-1-positive pregnant women treated with a nevirapine-containing regimen between May 2002 and July 2004 was conducted. Selection criteria for inclusion in the analysis were: (a) taking ARV for more than 14 days; (b) baseline values of transaminases below the threshold of 2.5 times the upper limit of normal (ULN). The women were on a nevirapine-containing regimen for a median of 127 days [interquartile range (IQR) 86-190 days], starting on average at the 27th week of gestation (standard deviation+/-9.5) and continuing up to a maximum of 6 months after delivery. All women were offered formula milk to feed the babies. Highly active antiretroviral therapy (HAART) was continued beyond 6 months only if the patient qualified on the first visit. The main outcome measures were incidence of hepatotoxicity, skin rashes and Stevens-Johnson syndrome. Multivariate analysis to assess the impact of several factors on the adverse reaction rate was performed. RESULTS: As of 1 August 2004, 554 pregnancies reached term, 96 women were still pregnant, and 53 women dropped out of the programme before giving birth. After 2 months of therapy the percentage of patients with a viral load less than 1000 HIV-1 RNA copies/mL increased to 78.6%; average CD4 cell counts increased from 490 cells/microL before therapy to 630 after therapy. The incidence of grade 3-4 adverse reactions (hepatotoxicity, skin rashes and Stevens-Johnson syndrome) was 6.5, 2.4 and 1.1%, respectively. Five women died during pregnancy (0.88%). Only one of the deaths could be associated with ARV treatment. CONCLUSION: Nevirapine-containing regimens in pregnant woman, at all CD4 cell count levels, appear to be safe in African settings.

RESUMO

The evaluation of the demand for assistance requires instruments and procedures scientifically validated as being effective. The aim of this paper is to present the results of a survey on the demand for assistance by a sector of the population, with an approach based on validated instruments and standardised procedures. The survey was carried out on a sample of 1,245 elderly persons (610 in Rome and 635 in Viterbo), who represent the over sixty-five year olds, resident in the Local Health Authority Roma D area and in the Local Health Authority of Viterbo. All the subjects were given the questionnaire for the Geriatric Functional Evaluation (GFE). Around 30% of over sixty-five year olds needs assistance. The Final Brief Evaluation indicates that 8% (CL 95%: 7.2-8.8) of the people interviewed need health and social services at the time of the study, and 20.6% more (CL95%: 19.5-21.7), should be carefully monitored in order to provide supportive, even if only social, services. Around 20.7% (CL95% 19.6-21.8) suffers from neurological pathologies and is characterised by a reduced functional capacity, as pointed out by the Multiple Correspondence Analysis. The combination of neuropathy and need of physical rehabilitation service is relevant part of the need for assistance. The approach used makes it possible to find out about situations of frailty in advance, so that a suitable plan of assistance in the area surveyed is possible.

RESUMO

Ensuring high levels of adherence to highly active anti-retroviral therapy (HAART) is a priority in treating people living with AIDS. This study reports the rates of adherence of patients served by DREAM (Drug Resource Enhancement against AIDS and Malnutrition) in the city of Matola, Mozambique. DREAM, an innovative programme tailored for Africa, was implemented by the Community of Sant'Egidio in August 2001. DREAM provides patients with anti-retroviral drugs and laboratory tests at no charge, and is based on a particular strategy of health education and organization of services designed for a population that is predominantly poor and has a low level of formal education. This study analyzes the adherence of 154 patients over a period of 6 months. In evaluating adherence, two indicators were used: (1) the percentage of appointments kept for check-ups, tests and the collection of medicine, and (2) the overall change in the patients' blood chemistry over the 6-month period. Of the 154 patients, 127 (82.5%) kept more than 90% of their appointments. Adherence to the programme was further confirmed by a relevant increase of hemoglobin levels and CD4 counts, and a significant decrease in the viral loads among the 154 patients.

RESUMO

The aim of this study is to analyse the condition of the elderly of Rome through a multidimensional instrument to determine their assistance needs. To this purpose a sample composed by 693 over 65 subjects was selected (430 women and 263 men). The Geriatric Functional Rating Scale of Grauer was administered to them. The questionnaire is divided into 7 sections (physical health, mental health, functional skills, support to the collectivity, type of housing, social relationships and economic situation); they enable to evaluate the dependency level of each subject. On the base of each area score a total score is obtained which divides the elderly into three categories according to their assistance need. The whole information collected in the single areas led to a definition of non self-sufficiency for 4.9% of the interviewed people and of partial self-sufficiency for 5.3%, the rest of the sample turned out composed by subjects able to live in an autonomous way. This sample of elderly (about 10%) is that on which it is possible to intervene with social and/or health home care plans in order to limit institutionalization.

RESUMO

The reaction of H2O2 with 4-substituted aryl alkyl sulfides (4-XC6H4SR), catalysed by lignin peroxidase (LiP) from Phanerochaete chrysosporium, leads to the formation of sulfoxides, accompanied by diaryl disulfides. The yields of sulfoxide are greater than 95% when X = OMe, but decrease significantly as the electron donating power of the substituent decreases. No reaction is observed for X = CN. The bulkiness of the R group has very little influence on the efficiency of the reaction, except for R = tBu. The reaction exhibits enantioselectivity (up to 62% enantiomeric excess with X = Br, with preferential formation of the sulfoxide with S configuration). Enantioselectivity decreases with increasing electron density of the sulfide. Experiments in H218O show partial or no incorporation of the labelled oxygen into the sulfoxide, with the extent of incorporation decreasing as the ring substituents become more electron-withdrawing. On the basis of these results, it is suggested that LiP compound I (formed by reaction between the native enzyme and H2O2), reacts with the sulfide to form a sulfide radical cation and LiP compound II. The radical cation is then converted to sulfoxide either by reaction with the medium or by a reaction with compound II, the competition between these two pathways depending on the stability of the radical cation.

RESUMO

In order to assess child malnutrition, an anthropometric cross-sectional survey of children aged 0-36 months was conducted in selected rural, urban and mountainous areas of Northern Albania in May 1997. The results showed a high prevalence of low anthropometric indices in rural and mountainous areas with a trend of similar magnitude in northern rural areas. In Northern Albania child malnutrition is a public health priority. As the main risk factor for underweight we found a recent history of diarrhoea (OR = 2.45) together with female gender (OR = 2.28), rural (OR = 2.09) or mountain (OR = 1.61) residency. Absence of sanitation, marker of poor housing conditions, also showed a significant association (OR = 1.55) with underweight. Low birthweight (OR = 1.12) was confirmed as an important risk factor for underweight condition. In conclusion these findings underline the importance of support appropriate mother and child health and nutritional programmes in rural areas of Northern Albania.
