Measles vaccine uptake among Italian medical students compared to the pre-COVID-19 era

The COVID-19 pandemic has severely affected health systems worldwide and raised the issue of vaccine hesitancy. In 2022, the World Health Organization reported an outbreak of measles infection among people over 20 years of age in the European Region. Previous studies found low rates of measles immunization among Italian healthcare workers (HCWs) and medical students. Vaccine hesitancy is a relevant cause of low immunization rate among HCWs and the general population. We aim to evaluate the measles vaccine uptake among medical students of a large teaching hospital, compared to the pre-pandemic period. This is a retrospective observational study, that evaluated the immune status and the vaccine acceptance rate for measles in medical students at the University of Tor Vergata, Rome, who underwent occupational health surveillance from 1 January to 1 December 2022. We also compared the data with the results of a pre-pandemic survey conducted in 2018. Vaccine uptake among unprotected medical students was 59.5%. The data showed no significant difference in vaccine uptake compared with the pre-COVID-19 period. Conversely, the rate of serologically immune subjects to measles increased from 89.66% in 2018 to 97.45% in 2022 as a result of the recent mandatory vaccination policy. Despite efforts to tackle vaccine hesitancy during the COVID-19 pandemic, measles vaccine uptake is still low among young adults starting their medical training, and their compliance with free workplace vaccination offers is suboptimal. Occupational health services should raise awareness among workers and work together to implement strategies to achieve comprehensive measles vaccination coverage among occupational health workers.

Serological Evaluation for Measles among Italian and Foreign Medical Students in a University Hospital in Rome

BACKGROUND

Measles infection in the hospital setting is a major issue. Despite the availability of an effective vaccine, measles outbreaks continue to occur in some European countries. We aimed to evaluate the immunological status of medical students attending the Tor Vergata Polyclinic (PTV).

METHODS

Measles antibodies titers were assessed by venipuncture on a sample of 2717 medical students who underwent annual health surveillance visits from January 2021 to March 2023. Subjects showing serum IgG values above 1.0 S/CO were considered serologically protected. Personal data, country of origin, and main demographic characteristic were also collected.

RESULTS

66.7% (1467 Italian and 346 foreign) of medical students showed protective IgG antibodies levels. Female students were serologically immune more frequently than males (68.6% vs. 63.3%; p < 0.01 at Chi2). The mean antibody titer was 1.72 S/CO, significantly higher in females than males (1.67 vs. 1.75, respectively; p < 0.05), and significantly related to age (p < 0.01). Albanian students, who were the largest foreign population in our study, showed a low serological protection rate (40/90: 44.4%).

CONCLUSIONS

The proportion of serologically non-immune students is high, raising concerns about the possible risk of hospital transmission. Substantial differences in the rate of immunity have been found between subjects coming from different parts of Europe and the world. Pre-training assessment of all medical students and vaccination of susceptible individuals is highly recommended, particularly for those from low immunization rate countries.

Interventions to increase uptake of influenza vaccination in pregnancy: A systematic review and meta-analysis

BACKGROUND

Maternal influenza vaccination has been introduced in several countries to prevent influenza-related morbidity and mortality in pregnant women, fetuses, and infants too young to be vaccinated.

OBJECTIVES

To analyze the available randomized controlled trials (RCTs) on the effectiveness of pregnant women-focused interventions to increase influenza vaccination uptake during pregnancy.

SEARCH STRATEGY

Medline, CINAHL, Scopus, Web of Science, and Cochrane Trial were searched on August 25, 2021.

SELECTION CRITERIA

RCTs assessing the effectiveness of pregnant women-focused interventions in increasing influenza vaccination among pregnant women were included.

DATA COLLECTION AND ANALYSIS

Two independent reviewers extracted data. A random-effects meta-analysis was conducted to estimate pooled odds ratios (ORs).

MAIN RESULTS

Seven RCTs were selected. Overall, the interventions had a significant effect in increasing influenza vaccination during pregnancy compared with standard care (OR 1.78, 95% confidence interval [CI] 1.25-2.54; P = 0.001; I²  = 67%). However, subgroup analysis suggested that influenza vaccination uptake only was associated with educational interventions (OR 2.71, 95% CI 1.93-3.81; P < 0.001; I²  = 0%).

CONCLUSIONS

We found that several educational interventions for pregnant women can effectively increase influenza vaccination uptake in this population. Specifically, pamphlets, websites, and brief one-to-one education can be effective tools.

Improvement in dietary diversity and feeding habits of malnourished under-five children attending supplementary feeding programmmes: a community-based cross-sectional study in Zambia

A community-based cross-sectional study was conducted on 390 under-five malnourished children enrolled in the Rainbow Project supplementary feeding programmmes-SFPs. Dietary diversity, feeding habits and nutritional status at admission (T1) and at discharge (T2) were compared. At T1 the diet was monotonous and unbalanced, with a progressive decline in dietary diversity and anthropometric values noted with children's age growth (p < 0.001). Significant improvements were registered at T2: DDS 5.1 ± 1.1 SD vs. 8.3 ± 1.0 SD; meal frequency 3.0 ± 0.6 SD vs. 4.9 ± 0.2 SD; animal-protein consumed 62.8% vs. 90.5%; drinking water treated 41.0% vs. 97.2%. At T1, the risk of having ZMUAC < 2.5SD increased when teenage motherhood (AOR: 5.3; CI: 1.8-15.2; p = 0.002), followed by children's age >2 years (AOR: 1.9; CI: 1.1-3.5; p = 0.020). Children's age was associated with an increased risk of WAZ < 2.5 SD (AOR: 4.9; CI: 2.4-10.4; p < 0.001). When considering inadequate DDS, the variable associated was breastfeeding cessation (AOR: 12.0; CI: 4.6-31.4; p < 0.001). Rainbow's SFPs have proved effective in treating under-five malnourished children, irrespective of the severity of malnutrition.

A novel, integrated approach for understanding and investigating Healthcare Associated Infections: A risk factors constellation analysis

INTRODUCTION

Healthcare-associated infections (HAIs) and antimicrobial resistance (AMR) are major public health threats in upper- and lower-middle-income countries. Electronic health records (EHRs) are an invaluable source of data for achieving different goals, including the early detection of HAIs and AMR clusters within healthcare settings; evaluation of attributable incidence, mortality, and disability-adjusted life years (DALYs); and implementation of governance policies. In Italy, the burden of HAIs is estimated to be 702.53 DALYs per 100,000 population, which has the same magnitude as the burden of ischemic heart disease. However, data in EHRs are usually not homogeneous, not properly linked and engineered, or not easily compared with other data. Moreover, without a proper epidemiological approach, the relevant information may not be detected. In this retrospective observational study, we established and engineered a new management system on the basis of the integration of microbiology laboratory data from the university hospital "Policlinico Tor Vergata" (PTV) in Italy with hospital discharge forms (HDFs) and clinical record data. All data are currently available in separate EHRs. We propose an original approach for monitoring alert microorganisms and for consequently estimating HAIs for the entire period of 2018.

METHODS

Data extraction was performed by analyzing HDFs in the databases of the Hospital Information System. Data were compiled using the AREAS-ADT information system and ICD-9-CM codes. Quantitative and qualitative variables and diagnostic-related groups were produced by processing the resulting integrated databases. The results of research requests for HAI microorganisms and AMR profiles sent by the departments of PTV from 01/01/2018 to 31/12/2018 and the date of collection were extracted from the database of the Complex Operational Unit of Microbiology and then integrated.

RESULTS

We were able to provide a complete and richly detailed profile of the estimated HAIs and to correlate them with the information contained in the HDFs and those available from the microbiology laboratory. We also identified the infection profile of the investigated hospital and estimated the distribution of coinfections by two or more microorganisms of concern. Our data were consistent with those in the literature, particularly the increase in mortality, length of stay, and risk of death associated with infections with Staphylococcus spp, Pseudomonas aeruginosa, Klebsiella pneumoniae, Clostridioides difficile, Candida spp., and Acinetobacter baumannii. Even though less than 10% of the detected HAIs showed at least one infection caused by an antimicrobial resistant bacterium, the contribution of AMR to the overall risk of increased mortality was extremely high.

CONCLUSIONS

The increasing availability of health data stored in EHRs represents a unique opportunity for the accurate identification of any factor that contributes to the diffusion of HAIs and AMR and for the prompt implementation of effective corrective measures. That said, artificial intelligence might be the future of health data analysis because it may allow for the early identification of patients who are more exposed to the risk of HAIs and for a more efficient monitoring of HAI sources and outbreaks. However, challenges concerning codification, integration, and standardization of health data recording and analysis still need to be addressed.

Exploring Tdap and influenza vaccine uptake and its determinants in pregnancy: a cross-sectional study

Background

The literature claims that an increased risk of complications from pertussis and influenza exists for pregnant women and infants. Maternal tetanus, diphtheria, and acellular pertussis (Tdap) and influenza vaccines seem to decrease this risk so that several countries are committed to increase vaccination uptake, but not all of them know their own vaccination coverage and factors that motivate this population to vaccination.

Study Design

A cross-sectional survey was conducted.

Methods

We conducted this survey to estimate among pregnant women: 1) the vaccine coverage, 2) the availability of information, 3) the knowledge about maternal Tdap and influenza vaccination, 4) the factors that could have driven unvaccinated pregnant women to have themselves vaccinated. In addition, determinants of Tdap and influenza vaccine uptake and correct knowledge about vaccine-preventable diseases and vaccination in pregnancy were assessed using univariate and multivariate analyses.

Results

Of the 250 women included in the present study, only 58 (23.2%, 95% Confidence Interval (CI): 18-28.4%) and 21 (8.1%, 95% CI: 5-11.8%) reported that they had been vaccinated with Tdap and influenza vaccine, respectively, during their current pregnancy. The most common reasons cited for getting themselves vaccinated was having background knowledge of the health problems due to the diseases prevented by Tdap and influenza vaccines, awareness regarding these vaccines being recommended in pregnancy, knowledge of their effectiveness and/or side effects, and having been informed about vaccination by a healthcare professional.

Conclusions

Influenza and Tdap vaccine uptake among pregnant women in Italy is low, however, the present study showed that women are available to get vaccinated during pregnancy when adequately informed about the vaccines recommended.

Parents' and caregivers' role toward childhood vaccination in Albania: assessment of predictors of vaccine hesitancy

Background

Vaccination has saved millions of lives through the protection of individuals and populations from communicable diseases. Vaccine hesitancy, defined as the delay in acceptance or refusal of vaccines despite the availability of vaccination services, has become a growing global concern. The objective of this study was to investigate parents'/caregivers' hesitancy toward childhood vaccination and its predictors in Albania.

Study design

A cross-sectional survey was conducted.

Methods

The data comes from a survey conducted on a sample of parents/caregivers (89.6% mothers) of children aged 6 months to 8 years at health care vaccination centers in seven Albanian cities from December 2020 to February 2021. Parents/caregivers (one per child) were interviewed by trained healthcare staff using a standardized questionnaire on six main content domains, including immunization behavior, beliefs about vaccine safety and efficacy, attitudes about vaccines, vaccination confidence, estimation of vaccine delay, and the intention to immunize children against SARS-CoV-2, and a self-reported hesitancy. The Albanian Ministry of Health approved the questionnaire, after it was translated, validated and adapted to the local setting. Statistical analyses included independent sample t-tests (p<0.05) and a logistic regression (OR; 95% C.I.).

Results

A total of 475 parents/caregivers of children aged from 6 months to 8 years, attending childhood vaccination in public health services, were interviewed. To the question "how hesitant you are about childhood vaccination", a high number of parents/caregivers (46%) responded that they do not feel hesitant at all, and 32% were not hesitant, a small number of parents/caregivers said they are very hesitant (5%) or somewhat hesitant (12%). A binary logistic model was fitted to the data to test the hypothesis regarding the relationship between parental vaccine hesitancy and possible predictors. A lower parental attitude toward childhood vaccines (OR = 3.7; 95% C.I. 1.102-12.421), a health center with a high vaccine delay (OR = 2.878; C.I. 95% 1.735-4.773), and low confidence in health staff information (OR = 2.042; 95% C.I. 1.156-3.605) were all independent predictors of parental vaccine hesitancy. Regarding intention to vaccinate children against COVID-19, when available, nearly 75% of parents/caregivers showed hesitancy.

Conclusions

Our results highlighted the role of positive parents'/caregivers' attitudes toward childhood vaccines followed by high staff confidence and good health center organization in order to deal with vaccine hesitancy, particularly for traditional and well-known childhood vaccines. Nevertheless, the hesitancy can be a critical barrier for childhood vaccination when we have to introduce a new vaccine, as is demonstrated in the recent vaccination campaign against the ongoing pandemic of SARS-CoV2.

Reduction of Waiting Times and Patients Leaving Without Being Seen in the Tertiary Pediatric Emergency Department: A Comparative Observational Study

OBJECTIVES

Analyze the effectiveness of an intervention to reduce waiting time and patients leaving without being seen in the pediatric emergency department.

METHODS

A comparative observational study was carried out from November 2018 to April 2019.Patients aged 3 months to 17 years were included. The new organizational model consisted of a dedicated outpatients' clinic for nonurgent codes and a fast track for traumatic and surgical emergency cases.

RESULTS

The comparative group included 14,822, and the intervention group included 15,585 patients. The new organizational model significantly reduced the numbers of patients who left the ED without being seen from 12.9% to 5.9%.

CONCLUSIONS

This new organizational model in the pediatric emergency department could be successfully used to reduce overcrowding, waiting time, and the numbers of patients leaving without being seen. However, more needs to be done by the pediatric services in the community to reduce nonurgent accesses to the emergency department.

The exacerbated prevalence of acute malnutrition and growth retardation in Roma children living in camps

Background

Child malnutrition is still a concern in marginalized groups of populations, such as immigrants living in very low socio-economic conditions. Roma children are within the most hard-to-reach populations, susceptible to undernutrition and growth retardation. In the city of Rome (Italy), the Hospital “Bambino Gesù”, in collaboration with the Catholic Association Community of Saint’Egidio, is dedicating free services for the health and nutritional needs of vulnerable people.

Methods

A retrospective analysis was conducted on immigrant children visited at different ages (0–11 years old). Records including nutritional and growth assessment were collected from 2016 up to May 2020. Malnutrition was classified following the WHO 2006 standards. Data for Roma children living in extra-urban camps and non-Roma immigrant children living in urban areas were analyzed, odds ratios and univariate binary regressions were performed to investigate the risk of malnutrition within the two groups.

Results

A sample of 414 children (57% under-five; 51.9% Roma), was included in the database. In the under-five children, underweight accounted for 7.6%, stunting for 11.7%, and wasting for 2.9%. The first year of life was the most crucial for nutritional status. Compared to the counterpart, Roma children accounted for nearly the total rate of malnutrition (wasting 4.8% vs. 1%; stunting 21.4% vs. 2%; underweight 14.2% vs. 1%). Univariate logistic regression confirmed under-five Roma children being at the highest risk of stunting at 12 months (OR: 16.1; CI 2–132; p = 0.01).

When considering the 176 school-aged children, undernutrition affected most Roma children (13% vs 1.9%), followed by stunting (5.8% vs 0.9%). Univariate logistic regression confirmed that Roma school-aged children were more likely to be underweight (OR: 7.8; CI 1.6–37.6; p = 0.01).

Conclusions

Malnutrition in immigrant children is still of high concern in Italy. Its prevalence in Roma children living in extra-urban camps exceeds that of immigrant children living in urban areas and the rates of underweight, stunting and wasting of Roma children living in the Balkans. This exacerbating condition highlights the need of better assisting this fragile population that is at most risk of poverty, food insecurity and social exclusion in Italy, particularly during this pandemic crisis.

Pediatric nurses in pediatricians' offices: a survey for primary care pediatricians

BACKGROUND

The role played by nurses in caring for children in pediatricians' officies in the community is crucial to ensure integrated care. In Italy, pediatricians are responsible for the health of children aged 0-14 years living in the community. This study aimed to describe Italian primary care pediatricians' opinions about the usefulness of several nursing activities that pediatric nurses could perform in pediatricians' offices.

METHODS

An online survey with pediatricians working in primary care in Italy was conducted between April-December 2018. A 40-item questionnaire was used to assess four types of nursing activities: clinical care, healthcare education, disease prevention, and organizational activities. The answers ranged from 1 (not useful at all) to 6 (very useful). Moreover, three open-ended questions completed the questionnaire.

RESULTS

Overall, 707 pediatricians completed the online survey. Participants were mainly female (63%), with a mean age of 57.74 (SD = 6.42). The presence of a pediatric nurse within the pediatrician's office was considered very useful, especially for healthcare education (Mean 4.90; SD 1.12) and disease prevention (Mean 4.82; SD 1.11). Multivariate analysis confirmed that pediatricians 'with less working experience', 'having their office in a small town', and 'collaborating with a secretary and other workers in the office' rated the nurse's activities significantly more useful.

CONCLUSIONS

A pediatric nurse in the pediatrician's office can significantly contribute to many activities for children and their families in the community. These activities include clinical care, healthcare education, disease prevention, and the organizational processes of the office. Synergic professional activity between pediatricians and pediatric nurses could ensure higher health care standards in the primary care setting.

COVID-19 vaccination in pregnancy and postpartum

Pregnant women were excluded from the initial phase 3 clinical trials of COVID-19 vaccines resulting in limited data on their efficacy and safety during pregnancy and postpartum. As a result, since December 2020, there has been conflicting advice from public health, governmental, and professional authorities on this matter. From the end of 2020 up to now, some consensus guidance has been published with a prevalent precautionary approach on the administration of vaccines in pregnant women, in breastfeeding ones, or for those who are planning a pregnancy (either spontaneously or with assisted technologies). After the first few months of vaccine administration in some countries, more permissiveness seems to prevail, although with inconsistencies. Some little indicative advice, their inconsistency around the world and their changes in a short time have probably disoriented both women and their health care providers and placed the burden of decision making upon women and their health care providers without information to assist in making an informed choice. We reviewed the COVID-19 vaccination guidance for pregnant and breastfeeding women published to date and evidence from cases of unplanned pregnancy during the course of vaccine trials, preclinical experimental and observational clinical studies, and discuss their implications. In this way, we have tried to identify the safety of COVID-19 vaccines for pregnant or breastfeeding women, and their offspring.

COVID-19 vaccination in pregnancy and postpartum

AIM

To identify whether COVID-19 vaccines should be administered in pregnant and breastfeeding women by reviewing the guidance and other evidence.

METHODS

We reviewed the COVID-19 vaccination guidance for pregnant and breastfeeding women published to date and evidence from preclinical experimental and observational clinical studies, and discuss their implications.

RESULTS

Pregnant women were excluded from the initial phase 3 clinical trials of COVID-19 vaccines resulting in limited data on their efficacy and safety during pregnancy and postpartum. As a result, since December 2020, there has been conflicting advice from public health, governmental, and professional authorities on this matter. From the end of 2020 up to now, some consensus guidance has been published with a prevalent precautionary approach on the administration of vaccines in pregnant women, in breastfeeding ones, or for those who are planning a pregnancy (either spontaneously or with assisted technologies). After the first few months of vaccine administration in some countries, more permissiveness seems to prevail, although with inconsistencies. At the moment, the results obtained by preclinical experimental and observational clinical studies suggest that the risks of the maternal COVID-19 outweigh the undocumented and hypothetical risks of the COVID-19 vaccines in pregnancy. Also, until two viral vector COVID-19 vaccines were associated with very rare thromboembolic events, all guidance had agreed that all approved COVID-19 vaccines could be administered in pregnancy. Actually, some concern has been expressed.

CONCLUSION

COVID-19 vaccines administered in pregnancy can reduce the risk of severe COVID-19 and their serious consequences for mothers and their offspring. However, many aspects remain to be clarified.

Epidemiology of Hypoalbuminemia in Hospitalized Patients: A Clinical Matter or an Emerging Public Health Problem?

Serum albumin levels are strongly associated with the morbidity, prognosis, and mortality rates of patients with hypoalbuminemia, which is a frequent problem during hospitalization. An observational retrospective study was carried out to analyze changes in albumin levels in hospitalized patients at the “Fondazione Policlinico Tor Vergata—PTV” in 2018. The prevalence of preexisting hypoalbuminemia at the time of discharge from hospital was investigated using a sample of 9428 patients. Information was collected from the discharge files recorded in the central informatics system of the hospital. Analysis of albumin levels at admission and at discharge was conducted by classes of albuminemia and then stratified by age. At the time of admission, hypoalbuminemia was found to be present in more than half of the sample, with no sex differences. The serum albumin level tended to decrease with age, with pathologic levels appearing from 50 years and progressive worsening thereafter. The condition of marked and mild hypoalbuminemia was more prevalent in patients over 65 years of age. Our findings suggest that hypoalbuminemia should be considered a dangerous condition in itself and a serious public health problem. We aimed to emphasize the role of albumin as useful marker of the in-hospital malnutrition and frailty, to be integrated in the routinely assessment of patients for reconsidering ad hoc healthcare pathways after discharge from hospital, especially when dealing with fragile populations.

Pathways to healthcare for migrants and vulnerable people inclusion: the experience of Genti di Pace

Issue

Chronic and acute diseases affects migrants and vulnerable people who often face barriers in accessing health care services. Here is the description of an innovative health center (HC) developed for identifying barriers and facilitating access to health care services of hard-to-reach (HTR) people in Rome.

Description of the Problem

The Community of Sant'Egidio together with the “Migrant Health Unit” of ASL Roma 1 has established an innovative HC program aimed to improve health outcomes in HTR urban population. One of the main Public Health challenge is to reduce inequalities among migrants and vulnerable people through improving access to health services. Data here analysed were collected during 2019.

Results

897 migrants and vulnerable people received heath care assistance. 52.4% were females, mean age 40.7±21.4 ds, 16.3% aged under 18 years and 69.6% were between 18-64 years. Countries of provenance: 56.8% Eastern Europe (Bosnia and Romania), 16.8% South America and 15.2% North Africa. 3.2% were refugees. Among 1986 health interventions 56.3% were general medical visits, 35.4% prescriptions and free drugs distribution, 4.1% children growth controls and baby milk supplies, 3.6% specialist visits and only 0.3% were sending to the Emergency Room.

Lessons

Improving the access to health care services of migrants is both a public health and an economic goal. The increase in chronic-degenerative diseases underlines the need to facilitate access to health services, also through collaboration networks between public and private social. This allows continuity in treatment, which has great meaning of secondary prevention, as well as rationalization of resources, reducing an improper use of the Emergency Room, which provides occasional intervention, but does not integrate into an efficient/effective therapeutic path.

Key messages

Promoting health care services like this can reduce barriers, improve health outcomes in migrants and increase sustainability of the NHS. Improving access to public and private social health services is important especially in presence of chronic-diseases which require continuous therapies and examinations.

Maternal tetanus, diphtheria, and acellular pertussis (Tdap) and influenza immunization: an overview

BACKGROUND

Maternal tetanus, diphtheria, and acellular pertussis (Tdap) and influenza immunization for women during pregnancy (the so-called "maternal immunization") has been introduced in several countries, and recently also in Italy, to protect mother and fetus during pregnancy, infant in his first months of life and mother during postpartum period. However, very low vaccination coverage rates have been reached due to several variables.

METHODS

A literature search was conducted on PubMed and Embase, including any experimental or observational studies, to assesses existing evidence on the effectiveness, efficacy, safety and optimal timing of administration of Tdap and influenza immunization in pregnancy for mothers and their infants. The search was finalized in August 2019.

RESULTS

Reviewing the literature, we identified only a few studies that, among several maternal and infant outcomes, found sporadic significant associations with maternal influenza immunization and even less with Tdap immunization. Moreover, most of the authors of these studies explained these findings as a result of residual confounding effect. The effectiveness of maternal influenza immunization is more complicated to prove than the effectiveness of Tdap immunization because of several reasons. Not all nations recommend and offer vaccines in the same weeks of pregnancy and this one manifests the complexity in defining the best timing for Tdap or influenza immunization.

CONCLUSIONS

The safety of maternal Tdap or influenza immunization is supported by the evidence so far, however, regular surveillance should be maintained, especially with regard to the influenza vaccine that changes in formulation each year. There is a need to optimize the timing of vaccination in pregnancy and to have a national system of detection of maternal immunization in each country.

Access to health care, nutrition and dietary habits among school-age children living in socio-economic inequality contexts: results from the "ForGood: Sport is Well-Being" programme

Social frailty is a warring phenomenon in Europe, negatively impacting children's health and nutrition. We present the results of a social programme facilitating access to physical activities for vulnerable children in Italy. 311 school-age children enrolled in the programme between 2015 and 2017 were assessed for health and lifestyle, anthropometric and nutritional status. Data were compared by origin (Italians vs. immigrants) and then immigrants were split into sub-groups: first- and second-generation. Poor socio-economic status exposed children to a lack of access to health services, and drove imbalanced eating behaviour. 20.8% of children were not registered with the National Health Services (immigrants p < .0001); 22% were not fully vaccinated (no differences between groups). A double burden of malnutrition coexisted: overweight was higher for Italians, underweight and poor linear growth for immigrants. Nearly 40% of children had a poor Mediterranean Diet adequacy (KIDMED index). Our findings show that when social programmes, besides their main scope of inclusion and integration, holistically approach their beneficiaries, they can play an important role in monitoring lifestyle conditions and facilitating access to primary health care.

A novel approach for geographical risk mapping of morbidity and mortality rates: the case of Val D'Agri, Italy

While associations between exposure to air pollutants and increased morbidity and mortality are well established, few rigorous studies on this issue are available. The aim of the current study is to implement a new approach to the spatial analysis of mortality and morbidity, based on testing for the presence of the same association in other areas of similar size. Additionally, we perform a case study in Val d'Agri (VA), an area of Basilicata Region, Southern Italy, where oil and natural gas extraction began in 1998. In order to examine the spatial distribution of morbidity and mortality in the region of interest, Hospital discharge (2001-2013) and mortality (2003-2014) rates for the main environment-related diseases were calculated. In addition, a comparison between the period 1980-1998 and the period 1999-2014 was performed for cardiovascular disease mortality. For the period under study, a neutral scenario emerged for cancer and respiratory diseases, where we found no differences in morbidity and mortality as compared to the national benchmark. In some cases significantly lower values (as compared to the nation-wide benchmark) were found. Conversely, a slight excess in morbidity and mortality (as compared to the nation-wide benchmark) emerged for cardiovascular diseases. Still, this excess was common to a number of municipalities in the surroundings of VA, and appeared to be already present in 1980. Higher rates of cardiovascular diseases, lower rates of neoplastic disorders no differences in mortality for respiratory causes (as compared to the nation-wide benchmark) were found in multiple areas of the region, and were therefore not specific to VA. In summary, our data do not support the hypothesis of a role of industrial activities related to oil extraction in VA in determining mortality and morbidity patterns and trends.

Early assessment of weight velocity can support frontline health workers in predicting malnutrition in HIV-exposed infants: preliminary results from a DREAM cohort in Malawi

BACKGROUND

Children born to HIV-positive mothers are particularly susceptible to malnutrition. Currently, monitoring programs rely on punctual anthropometric measurements to assess child growth. Growth velocities could be an additional tool in identifying critical time windows for prevention and implementation of early intervention for malnutrition.

METHODS

A retrospective analysis was conducted using data from 817 HIV exposed but uninfected children extracted from DREAM program database. By using the WHO reference for growth standards, patterns of weight velocity for different intervals of assessment from one to 18 months of age were explored. Odds ratios and multinomial logistic regressions between selected weight velocity Z-scores thresholds and successive malnutrition indices (at 6, 12, 18 months of age) were calculated.

RESULTS

Weight velocity was above the standard mean in the first 3 months, then progressively declined over time. In children with normal nutritional status, significant risks of becoming malnourished (mild malnutrition - underweight [OR 10.8; 95% CI: 4.5-26], chronic malnutrition - stunting [OR 8.3; 95% CI: 2-34.9] and acute malnutrition - wasting [OR 11.7; 95% CI: 1.5-90.5]) started when weight velocity Z-scores <0, at all interval ages. Multinomial regression showed that in the first 6 months, the weight velocity decrements strongly impacted on underweight (OR 17.9; 95% CI: 4-80.7), while the risk of Stunting occurred later at 18 months (OR 8.7; 95% CI: 4.3-17.6), with highest impact at the lowest thresholds.

CONCLUSIONS

The assessment of weight velocity Z-scores, coupled with the already validated malnutrition indices, can support frontline health workers in early prediction of child malnutrition and performing nutritional counselling in the context of HIV/AIDS and food insecurity.

Filling the Gaps for Enhancing the Effectiveness of Community-Based Programs Combining Treatment and Prevention of Child Malnutrition: Results from the Rainbow Project 2015⁻17 in Zambia

BACKGROUND

Child malnutrition, in all its forms, is a public health priority in Zambia. After implementations based on a previous evaluation in 2012⁻14 were made, the efficacy of the Rainbow Project Supplementary Feeding Programs (SFPs) for the integrated management of severe acute malnutrition (SAM), moderate acute malnutrition (MAM), and underweight was reassessed in 2015⁻17.

METHODS

The outcomes were compared with International Standards and with those of 2012⁻14. Cox proportional risk regression analysis was performed to identify predictors of mortality and defaulting.

RESULTS

The data for 900 under-five year-old malnourished children were analyzed. Rainbow's 2015⁻17 outcomes met International Standards, for total and also when stratified for different type of malnutrition. A better performance than 2012⁻14 was noted in the main areas previously identified as critical: mortality rates were halved (5.6% vs. 3.1%, p = 0.01); significant improvements in average weight gain and mean length of stay were registered for recovered children (p < 0.001). HIV infection (5.5; 1.9⁻15.9), WAZ <⁻3 (4.6; 1.3⁻16.1), and kwashiorkor (3.5; 1.2⁻9.5) remained the major predictors of mortality. Secondly, training community volunteers consistently increased the awareness of a child's HIV status (+30%; p < 0.001).

CONCLUSION

Rainbow SFPs provide an integrated community-based approach for the treatment and prevention of child malnutrition in Zambia, with its effectiveness significantly enhanced after the gaps in activities were filled.

. Nurses with pediatricians in pediatric outpatient clinics: a survey on family pediatricians' opinions.

INTRODUCTION

Pediatric nurses next to family pediatricians could contribute to several activities, included limiting inappropriate access to the emergency room.

AIM

To describe the perceived benefit of the activities that could be performed by pediatric nurses in the pediatrician's clinic according to the opinion of family pediatricians.

METHODS

Pilot on-line survey with family pediatricians, using list of activities grouped in four areas: "Care of pediatric patients with illnesses and disabilities", "Health education", "Prevention of diseases" and "Coordination and organizational activities". For each activity a judgement of benefit (1= not useful at all; 6= very useful) was reported.

RESULTS

Overall, 178 family pediatricians participated in the survey; 55% of them were female, mean age was 55 years. They rated as very useful both the presence of a pediatric nurse in their clinic (mean 5.37+1.06) and would recommend it to a colleague (5.36+1.05). Health education was perceived as the most important area of activity (4.88+0.97). The more they considered useful the pediatric nurse in their clinic, the higher they rated relevant the activities of the pediatric nurse (r=0.60-0.70). Older and more experienced pediatricians found less useful educational (r=-0.19 p<0.05; r=-0.23 p<0.01) and prevention (r=-0.18 p<0.05; r=-0.24 p<0.01) activities compared to younger and less experienced pediatricians.

CONCLUSIONS

Pediatricians consider very helpful a pediatric nurse in their clinic, for clinical, educational and organizational activities.

Trend and determinants of acute inpatient care for the elderly in Italy from 2001 to 2011

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.

Who will be lost? Identifying patients at risk of loss to follow-up in Malawi. The DREAM Program Experience

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.

CMV infection in a cohort of HIV-exposed infants born to mothers receiving antiretroviral therapy during pregnancy and breastfeeding

Antiretroviral therapy has been shown to reduce rates of congenital CMV infection. Little information is available on the possible impact of antiretroviral therapy on postnatal breastfeeding-associated CMV infection acquisition. A cohort of 89 HIV-infected mothers and their children was studied. Women received antiretroviral therapy from week 25 of gestation until 6 months postpartum or indefinitely if meeting the criteria for treatment. All women were evaluated for CMV IgG presence and CMV DNA in breast milk. Children were tested for CMV infection by either the presence of IgM or the presence of CMV DNA in plasma at 1, 6 and 12 months and by the presence of IgG at 24 months. All mothers had high titers of CMV DNA in breast milk (5.7 log at Month 1 and 5.1 log at Month 6). Cumulative CMV infection rates were 60.3 % at Month 6, 69 % at Month 12 and 96.4 % at Month 24. There was a significant negative correlation between the duration of antiretroviral treatment during pregnancy and levels of CMV DNA in breast milk at Month 1 (P = 0.033). There was a trend for a correlation between high titers of CMV DNA in breast milk at 6 months and CMV infection at 6 months (P = 0.069). In this cohort, more than 95 % of the children had acquired CMV infection by 2 years of age. Besides breastfeeding, which played a major role, also horizontal transmission between 1 and 2 years was certainly relevant in determining CMV infection acquisition.

Schistosoma haematobium infection, health and nutritional status in school-age children in a rural setting in Northern Senegal

BACKGROUND

The aim of this study was to investigate the occurrence of urinary schistosomiasis in school children in a rural village of Northern Senegal, and to evaluate the impact of this parasitic infection on children's health, growth, and nutritional status.

METHODS

A cross-sectional survey was carried out on 465 children resident in the village of Kassak Nord, in Senegal, in an area which is highly endemic for Schistosoma haematobium. Data on health, nutritional status and urinary schistosomiasis were collected.

RESULTS

The overall prevalence of urinary schistosomiasis in school children in Kassak was 47.4%. As for malnutrition, 29.7% of children were malnourished (BMI-for-age Z-score [BAZ] <-2) and 14.5% had a significant linear growth retardation (height-for-age Z-score [HAZ] <-2). Children with urinary schistosomiasis showed lower mean BAZ and HAZ than uninfected children (HAZ positives -0.7±1.4 vs. HAZ negatives -0.4±1.4, P=0.004; BAZ positives -1.5±1 vs. BAZ negatives -1.3±1.1, P=0.03). It was also found that infected children were at greater risk of malnutrition (BAZ<-2; OR 1.5; 95% CI 1.01-2.26).

CONCLUSIONS

The results of this study support the hypothesis that urinary schistosomiasis affects negatively childhood health and nutritional status and are of importance for planning intervention aimed to monitoring and control Urinary Schistosomiasis and malnutrition.

An assessment of option B implementation for the prevention of mother to child transmission in Dschang, Cameroon: results from the DREAM (Drug Resource Enhancement against AIDS and Malnutrition) cohort

Introduction

Scaling up of antiretroviral therapy (ART) to HIV+ pregnant women is crucial for the elimination of HIV infection in children. The aim of this study was to evaluate the feasibility and effectiveness of triple ART for Prevention of Mother-to Child Transmission (PMTCT) in Cameroon.

Methods

HIV-positive pregnant women attending the DREAM Centre of Dschang, Cameroon for prenatal care were enrolled in a prospective cohort study, and received ART until the end of breastfeeding or indefinitely if their CD4 count was <350mm³. Infants were evaluated for HIV infection at 1, 6 and 12 months of age.

Results

A total of 298 women were enrolled. Among them, 152 were already on established ART. Women were followed until 6 months after delivery with a retention rate of 92.6%. Eight women died. Those with a CD4 count <350 cells/mm³ during pregnancy had the highest mortality risk (RR 2.53; 95% CL= 1.86-3.44). The HIV transmission rate was 1.2% at 12 months with an HIV free survival of 91%. In the proportional Cox regression analysis, the following factors were positively associated with infant mortality: maternal CD4< 350 cells/mm³, no breastfeeding in the first 6 months of life, weight-for-age z score<-2.

Conclusion

Results confirm the feasibility and effectiveness of the implementation of Option B, with very low rates of HIV MTC transmission, and potential benefits to the health of mothers and infants with earlier initiation of ART. Breastfeeding again demonstrates to be highly beneficial for the growth and survival of HIV exposed children.

Transitional challenges of Medicine and Surgery in Albania

Data on the State of Art of Medicine and Surgery in Albania, are given in this short survey. From recent epidemiological data, conditioned by high rate of migration and territory problems, to problems arising from lack of technological supports and important changes in medical education. An analysis that we could do from the observatory of our Medical School, and international one, based on a strict collaboration among an international professor staff, mostly coming from Italian Universities, particularly the University of Rome, "Tor Vergata", co-founder of the "Catholic University Our Lady of Good Counsel" (UCNSBC). The integration between academics in UCNSBC and health personnel in health care offers some interesting opportunities in research. The recognized limited technological supports create the possibilities to adjust and ameliorate health care services, with the aim of a more convenient distribution of the available resources.

Malnutrition decreases the odds of attaining motor milestones in HIV exposed children: results from a paediatric DREAM cohort

OBJECTIVE

HIV and malnutrition are the two major causes of infant mortality in Sub-Saharan Africa. The study describes the impact of malnutrition on motor milestone development in HIV-exposed children.

DESIGN

Randomized community intervention trial (SMAC, Safe Milk for African Children).

SETTING AND PARTICIPANTS

Growth, motor development, and malnutrition were assessed in a sample of 76 HIV-exposed children, aged 0-24 months, at the Blantyre Dream Centre in Malawi.

MAIN OUTCOME MEASURES

We assessed growth and selected motor milestone achievement in agreement with WHO/UNICEF criteria. Odds ratios and 95%confidence intervals were calculated according to motor milestones and malnutrition indices. Multivariable logistic regression was performed with 18 months data.

RESULTS

High rates of malnutrition were observed. Underweight increased by 6.7/9.2 and 3.2/5.5 the odds of not standing alone and not walking alone at 15 and 18 months. Stunting increased by 9.7 the odds of not standing alone at 11 months and by 6.1 the odds of not walking alone at 18 months. Wasting increased by 5.5/10.3 the odds for not walking with assistance at 12 and 18 months. Low weight for age was associated with delay in walking at 18 months (HR=2.9).

CONCLUSION

Malnutrition in HIV-exposed children decreases the likelihood of adequate development.

Laboratory confirmation of clinically diagnosed malaria in a cohort of HIV-infected mothers and their children in Malawi

To avoid overdiagnosis, accuracy in the identification of true malaria cases is of critical importance. Samples (either whole blood, dried blood spots or plasma/serum) collected at the time of clinically diagnosed malaria episodes in a cohort of Malawian HIV-infected mothers and their children were retrospectively tested with the enzyme-linked immunosorbent assay (ELISA) for HRP-2 (histidine-rich protein 2) detection. There were 55 and 56 clinically diagnosed cases of malaria in mothers and children, respectively, with samples available for testing. Rates of laboratory-confirmed episodes were 20% (11 of 55) in mothers and 16.1% (9 of 56) in children. Hemoglobin was lower in children with confirmed malaria compared to those with clinical malaria diagnosis. The results of our study support the widespread use of rapid diagnostic tests.

Retention, transfer out and loss to follow-up two years after delivery in a cohort of HIV+ pregnant women in Malawi

In this study, we analysed in a cohort of pregnant women followed for two years the proportion of women remaining at the same clinic, those who transferred to other clinics, and those lost to follow-up. The possible determinants of the loss to follow-up were also assessed in a setting of postpartum discontinuation based on CD4+ count. A total of 311 pregnant women received antiretroviral therapy from week 25 of gestational age until six months postpartum (end of breastfeeding period), or indefinitely if meeting the criteria for treatment (baseline CD4+ <350 cells/mm(3)). Twenty-four months after delivery, six women had died, 247 were in active follow-up, 21 had transferred to another antiretroviral therapy clinic and 37 were lost to follow-up (rate of loss to follow-up 13%, 95% CI 9.1-16.9%). The presence of a baseline CD4+ count above 350 cells/mm(3) was associated with a ten-fold higher risk of loss to follow-up after six months of delivery (hazard ratio: 9.8, 95% CI 2.2-42.7, for baseline CD4 >350 cells/mm(3) versus baseline CD4+ count below 350 cells/mm(3), p = 0.002). This finding suggests that discontinuation of drugs when the risk of transmission has ceased can have a negative impact on the retention in care of these women.

A pharmacogenetics study in Mozambican patients treated with nevirapine: full resequencing of TRAF3IP2 gene shows a novel association with SJS/TEN susceptibility

Steven–Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) are severe adverse drug reactions, characterized by extensive epidermal detachment and erosions of mucous membrane. SJS/TEN is one of the most serious adverse reactions to Nevirapine (NVP) treatment, commonly used in developing countries as first-line treatment of human immunodeficiency virus infection. In the last years TRAF3IP2 gene variants had been described as associated with susceptibility to several diseases such as psoriasis and psoriatic arthritis. We hypothesized that this gene, involved in immune response and in NF-κB activation, could also be implicated in the SJS/TEN susceptibility. We performed a full resequencing of TRAF3IP2 gene in a population of patients treated with NVP. Twenty-seven patients with NVP-induced SJS/TEN and 78 controls, all from Mozambique, were enrolled. We identified eight exonic and three intronic already described variants. The case/control association analysis highlighted an association between the rs76228616 SNP in exon 2 and the SJS/TEN susceptibility. In particular, the variant allele (C) resulted significantly associated with a higher risk to develop SJS/TEN (p = 0.012 and OR = 3.65 (95% CI 1.33–10.01)). A multivariate analysis by logistic regression confirmed its significant contribution (p = 0.027, OR = 4.39 (95% CI 1.19–16.23)). In conclusion, our study suggests that a variant in TRAF3IP2 gene could be involved in susceptibility to SJS/TEN.

Hepatitis B virus mother-to-child transmission among HIV-infected women receiving lamivudine-containing antiretroviral regimens during pregnancy and breastfeeding

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.

Unequal access, low vaccination coverage, growth retardation rates among immigrants children in Italy exacerbated in Roma immigrants

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.

Viral sequence analysis of HIV-positive women and their infected children: insight on the timing of infection and on the transmission network

We used high-resolution phylogenetic methods in the context of mother-to-child transmission to obtain information on the timing of the infection and on the transmission network. A total of 33 pol sequences (from maternal peripheral blood, from breast milk, and from plasma of children) belonging to five cases of HIV infant transmission were studied. Using time-scaled phylogeny we were able to estimate that in two cases the transmission occurred after the recommended duration of breastfeeding, supporting a longer, not reported, duration of breastfeeding as a significant factor associated with HIV infant acquisition in this cohort. Among the postnatal infections we were also able to demonstrate that the cell-free virus in breast milk was the most likely population associated with the event of transmission. Our study showed that a coalescent-based model within a Bayesian statistical framework can provide important information that can contribute to optimizing preventive strategies.

Evaluation of the nutritional status of infants from mothers tested positive to HIV/AIDS in the health district of Dschang, Cameroon

INTRODUCTION

Poor infant feeding practices are common in Africa, resulting in physical and intellectual developmental impairments. Good feeding practices are crucial, especially in the first year of growth. HIV/AIDS has worsened the clinical and nutritional status of both mothers and their children, exacerbating high rates of malnutrition. The aim of this study was to assess by participative approach, the nutritional status of infants from mothers tested positive to HIV in the health district of Dschang.

METHODS

This is a cross sectional study with a period of recruitment of 2 years (2010-2012). Data Collection was done by the aim of a personal slip followed by training to strengthen the nutritional and hygienic capacity of targeted parents. Height and weight of infants were measured and body mass index (BMI) calculated.

RESULTS

Significant difference (p ≤ 0.05) was noticed in height-for-age z-score (HAZ) of girls aged between 1 to 2 years compared to 1-year old girls as well as to boys of all ages, defining them as stunted. Furthermore, the weight-for-age z-score (WAZ) results indicate that both girls and boys of all age are in moderate state of malnutrition. The results of BMI thinness classified according to gender and age groups, indicates that most infants (68/130, 52.3%) showed grade 2 thinness predominantly in 2-years old both boys and girls. However, no participants fall within the normal category for age and sex, as well as overweight and obesity categories.

CONCLUSION

Undernutrition exists among infants from mothers tested positive to HIV residing in Dschang, as most of the infants are underweight, and malnourished.

Reduction of maternal mortality with highly active antiretroviral therapy in a large cohort of HIV-infected pregnant women in Malawi and Mozambique

Background

HIV infection is a major contributor to maternal mortality in resource-limited settings. The Drug Resource Enhancement Against AIDS and Malnutrition Programme has been promoting HAART use during pregnancy and postpartum for Prevention-of-mother-to-child-HIV transmission (PMTCT) irrespective of maternal CD4 cell counts since 2002.

Methods

Records for all HIV+ pregnancies followed in Mozambique and Malawi from 6/2002 to 6/2010 were reviewed. The cohort was comprised by pregnancies where women were referred for PMTCT and started HAART during prenatal care (n = 8172, group 1) and pregnancies where women were referred on established HAART (n = 1978, group 2).

Results

10,150 pregnancies were followed. Median (IQR) baseline values were age 26 years (IQR:23–30), CD4 count 392 cells/mm³ (IQR:258–563), Viral Load log₁₀ 3.9 (IQR:3.2–4.4), BMI 23.4 (IQR:21.5–25.7), Hemoglobin 10.0 (IQR: 9.0–11.0). 101 maternal deaths (0.99%) occurred during pregnancy to 6 weeks postpartum: 87 (1.1%) in group 1 and 14 (0.7%) in group 2. Mortality was 1.3% in women with <than 350 CD4 cells/mm³ and 0.7% in women with greater than 350 CD4s cells/mm³ [OR = 1.9 (CL 1.3–2.9) p = 0.001]. Mortality was higher in patients with shorter antenatal HAART: 22/991 (2.2%) if less than 30 days and 79/9159 (0.9%) if 31 days or greater [OR = 2.6 (CL 1.6–4.2) p<0.001]. By multivariate analysis, shorter antenatal HAART (p<0.001), baseline values for CD4 cell count (p = 0.012), hemoglobin (p = 0.02), and BMI (p<0.001) were associated with mortality. Four years later, survival was 92% for women with shorter antenatal HAART and 98% for women on established therapy prior to pregnancy, p = 0.001.

Conclusions

Antiretrovirals for PMTCT purposes have significant impact on maternal mortality as do CD4 counts and nutritional status. In resource-limited settings, PMTCT programs should provide universal HAART to all HIV+ pregnant women given its impact in prevention of maternal death.

Maternal antiretroviral therapy for the prevention of mother-to-child transmission of HIV in Malawi: maternal and infant outcomes two years after delivery

Background

Optimized preventive strategies are needed to reach the objective of eliminating pediatric AIDS. This study aimed to define the determinants of residual HIV transmission in the context of maternal antiretroviral therapy (ART) administration to pregnant women, to assess infant safety of this strategy, and to evaluate its impact on maternal disease.

Methodology/Principal Findings

A total of 311 HIV-infected pregnant women were enrolled in Malawi in an observational study and received a nevirapine-based regimen from week 25 of gestation until 6 months after delivery (end of breastfeeding period) if their CD4+ count was > 350/mm³ at baseline (n = 147), or indefinitely if they met the criteria for treatment (n. 164). Mother/child pairs were followed until 2 years after delivery. The Kaplan-Meier method was used to estimate HIV transmission, maternal disease progression, and survival at 24 months. The rate of HIV infant infection was 3.2% [95% confidence intervals (CI) 1.0-5.4]. Six of the 8 transmissions occurred among mothers with baseline CD4+ count > 350/mm³. HIV-free survival of children was 85.8% (95% CI 81.4-90.1). Children born to mothers with baseline CD4+ count < 350/mm³ were at increased risk of death (hazard ratio 2.6, 95% CI 1.1-6.1). Among women who had stopped treatment the risk of progression to CD4+ count < 350/mm³ was 20.6% (95% CI 9.2-31.9) by 18 months of drug discontinuation.

Conclusions

HIV transmission in this cohort was rare however, it occurred in a significative proportion among women with high CD4+ counts. Strategies to improve treatment adherence should be implemented to further reduce HIV transmission. Mortality in the uninfected exposed children was the major determinant of HIV-free survival and was associated to maternal disease stage. Given the considerable proportion of women reaching the criteria for treatment within 18 months of drug discontinuation, life-long ART administration to HIV-infected women should be considered.

[Health Promotion and care of immigrant population in the eighth Municipality of Rome: the experience of the Medicine Service of Solidarity and the University Hospital of Tor Vergata]

The VIII Municipality of Rome is characterized by a high poverty rate, by the presence of many immigrant communities and by the lack of health services available to vulnerable social groups. In 2005 , the " Servizio di Medicina Solidale" of the University Hospital of "Tor Vergata", for the first time intervened in this Municipality regarding Immigrant Health. The paper describes the activities and organization of this service from January 2005 to December 2007. It demonstrates a complex epidemiological picture of 2,374 immigrants, characterized by a young population, mostly women with reproductive health issues, followed by children with infectious and nutritional problems and, ultimately, adults who accessed the service, firstly for gastroenterological problems, secondly for cardiovascular problems and finally for dysmetabolic disorders. The paper describes the culture-centered actions of Health Promotion and Health Education in order to improve health awareness and promote integration of immigrants. The study indicates that the limited number of hospital admissions ( n.20) with respect to the number of outpatient visits (n.70.000) in the first seven years of the service " Medicina Solidale" has significantly reduced the number of unnecessary admissions to emergency wards. In conclusion it is notable that the cost of such intervention results eight times inferior to emergency admissions and further confirms that a Community medicine approach is sustainable.

[Health and disability in the elderly: old paradigms and future prospects]

The projections regarding the ageing of the Italian population are cause for great concern; however, the ageing scenario may actually be interpreted in a more optimistic way. Theories formulated in the 80s envisaging a decline of mortality, morbidity and disability in the elderly are now confirmed and prefigure an unexpected decrease in disability rates in the elderly population. The aim of this review is to attempt to explain the reasons for this by analyzing the role played by the various determinants of health, in particular social isolation, which are likely to play an important role in the future as well.

Predicting trends in HIV-1 sexual transmission in sub-Saharan Africa through the Drug Resource Enhancement Against AIDS and Malnutrition model: antiretrovirals for 5 reduction of population infectivity, incidence and prevalence at the district level

BACKGROUND

The use of antiretrovirals to reduce the incidence of human immunodeficiency virus (HIV) infection has been evaluated in mathematical models as potential strategies for curtailing the epidemic. Cohort data from the Drug Resource Enhancement Against AIDS and Malnutrition (DREAM) Program was used to generate a realistic model for the HIV epidemic in sub-Saharan Africa.

METHODS

Two combined stochastic models were developed: patient and epidemic models. Models were combined using virus load as a parameter of infectivity. DREAM data that assessed patient care in Mozambique and Malawi were used to generate measures of infectivity, survival, and adherence. The Markov chain prediction model was used for the analysis of disease progression in treated and untreated patients. A partnership model was used to assess the probability that an infected individual would transmit HIV.

RESULTS

Data from 26565 patients followed up from January 2002 through July 2009 were analyzed with the model; 63% of patients were female, the median age was 35 years, and the median observation time was 25 months. In the model, a 5-fold reduction in infectivity (from 1.6% to 0.3%) occurred within 3 years when triple ART was used. The annual incidence of HIV infection declined from 7% to 2% in 2 years, and the prevalence was halved, from 12% to 6%, in 11 years. Mortality in HIV-infected individuals declined by 50% in 5 years. A cost analysis demonstrated economic efficiency after 4 years.

CONCLUSIONS

Our model, based on patient data, supports the hypothesis that treatment of all infected individuals translates into a drastic reduction in incident HIV infections. A targeted implementation strategy with massive population coverage is feasible in sub-Saharan Africa.

Nutritional rehabilitation of HIV-exposed infants in Malawi: results from the drug resources enhancement against AIDS and malnutrition program

Infant malnutrition in sub-Saharan Africa is a public health priority and a challenge in high HIV prevalence areas. The Drug Resources Enhancement Against AIDS and Malnutrition program, with multiple medical centers in Sub-Saharan Africa, developed an innovative intervention for the surveillance and control of malnutrition. In a pilot initiative, 36 HIV-exposed children were evaluated at baseline upon presentation for malnutrition and at six months post- treatment. Parameters included HIV-free survival, nutritional status and change in diet. Food diary data was entered and processed using the Nutrisurvey (WHO) software. At 6 months post-intervention, a significant improvement in anthropometric parameters was noted. Slowing of linear growth was observed in patients with malaria with a mean gain in centimetres of 4.4 ± 1.7 as compared to 5.6 ± 1.7 in children with no malaria, p < 0.048 (CL 95%: −2.32, −0.01). Dietary diversity scores increased from 5.3 ± 1.9 to 6.5 ± 1.3, p < 0.01 at 6 months. A significant increase (+25%, p < 0.02) in the number of children eating fish meals was noted. Our pilot data describes positive outcomes from a rehabilitative nutritional approach based on use of local foods, peer education, anthropometric and clinical monitoring in areas of high food insecurity. The relationship between malaria and linear growth retardation requires further investigation.

The impact of integrating food supplementation, nutritional education and HAART (Highly Active Antiretroviral Therapy) on the nutritional status of patients living with HIV/AIDS in Mozambique: results from the DREAM Programme

DREAM (Drug Resources Enhancement against AIDS and Malnutrition) is a multiregional health program active in Mozambique since 2002 and provides free of charge an integrating package of care consisting of peer to peer nutritional and health education, food supplementation, voluntary counseling and testing, immunological, virological, clinical assessment and HAART (Highly Active AntiRetroviral Treatment). The main goals of this paper are to describe the state of health and nutrition and the adequacy of the diet of a sample of HIV/AIDS patients in Mozambique on HAART and not. A single-arm retrospective cohort study was conducted. 106 HIV/AIDS adult patients (84 in HAART), all receiving food supplementation and peer-to-peer nutritional education, were randomly recruited in Mozambique in two public health centres where DREAM is running. The programme is characterized by: provision of HAART, clinical and laboratory monitoring, peer to peer health and nutritional education and food supplementation. We measured BMI, haemoglobin, viral load, CD4 count at baseline (T0) and after at least 1 year (T1). Dietary intake was estimated using 24h food recall and dietary diversity was assessed by using the Dietary Diversity Score (DDS) at T1. Overall, the patients'diet appeared to be quite balanced in nutrients. In the cohort not in HAART the mean BMI values showed an increases but not significant (initial value: 21.9 ± 2.9; final value: 22.5 ± 3.3 ) and the mean haemoglobin values (g/dl) showed a significant increases (initial value: 10.5+ 2.1; final value: 11.5 ± 1.7 p< 0.024) . In the cohort in HAART, both the mean of BMI value (initial value: 20.7 ± 3.9; final value: 21.9 ± 3.3 p< 0.001) and of haemoglobin (initial value: 9.9 ± 2.2; final value: 10.8 ± 1.7 p< 0.001) showed a higher significant increase. The increase in BMI was statistically associated with the DDS in HAART patients. In conclusion nutritional status improvement was observed in both cohorts. The improvement in BMI was significant and substantially higher in HAART patients because of the impact of HAART on nutritional status of AIDS patients. Subjects on HAART and with a DDS > 5, showed a substantial BMI gain. This association showed an additional expression of the synergic effect of integrating food supplementation, nutritional education and HAART on the nutritional status of African AIDS patients and also highlights the complementary role of an adequate and diversified diet in persons living with HIV/AIDS in resources limited settings.

Immunologic response to highly active antiretroviral therapy and mortality reduction in a cohort of human immunodeficiency virus-positive persons in Mozambique

Since February 2002, the Drug Resources Enhancement against AIDS and Malnutrition Program has provided highly active antiretroviral therapy (HAART) and immunologic and virologic monitoring free of charge. We conducted a cohort study of persons infected with human immunodeficiency virus in Mozambique. Only persons treated with HAART with available CD4 cell counts at baseline and ≥ 1 CD4 cell count after HAART were included. Survival analysis was applied to evaluate the prognostic value of CD4 cell counts measured at three months. Possible confounders were considered. A total of 753 persons who started HAART included; 59% were females. Median age was 34 years (range = 16-67 years), and the median CD4 cell count at baseline was 172 cells/mm3 (interquartile range = 87-261 cells/mm3, range = 0-1,322 cells/mm3). Overall, 105 persons (14%) died. Of these persons 54 (51%) developed AIDS before they died; 25 (3%) died during the first three months. After three months of therapy, the individual median CD4 cell count change from the baseline value was +101 cells/mm3 (interquartile range = +27 to +187 cells/mm3, range = -723 to +310 cells/mm3). A median CD4 increment of 100 cells/mm3 in three months was associated with a mortality reduction of 50% compared with an increase of < 50 cells (relative hazard of death adjusted for baseline CD4 cell count = 0.54, 95% confidence interval = 0.30-0.95). A good initial response to HAART was associated with a significant reduction of mortality. This finding supports the effectiveness of HAART in resource-poor settings.

[Evaluation and prevention of type II diabetes mellitus and cardiovascular diseases in obese children and adolescents: a public health intervention in a local health organisation in Rome (Italy)]

INTRODUCTION

Prevention of childhood obesity and of its complications is an increasingly important public health priority. During 2002-2003 a network of family paediatricians working in the territory of a local health organisation in Rome (Italy) was created, in order to evaluate the health status of obese children. A preferential diagnostic and therapeutic management workup procedure was then developed for these patients at the Paediatrics department of the "Policlinico Tor Vergata" (PTV) university teaching hospital in Rome (Italy).

METHODS

Family paediatricians invited children aged 6-14 years with a body mass index (BMI) above the 95th percentile, to a clinical consultation at PTV where each child then underwent a clinical evaluation (including blood pressure measurement and evaluation of family history of cardiovascular disease and type 2 diabetes mellitus) and laboratory testing (including oral glucose tolerance testing-OGTT, measurement of cholesterol and trygliceride levels). The BMI z score and insulin resistance index (HOMA-IR) were also calculated and pubertal stage was assessed.

RESULTS

Overall, 168 children, with a mean age of 11 years, were evaluated; 53% were males. The mean BMI z score was 2.43+/-0.45. Forty-four percent of children were found to be hypertensive and 28.3% had a positive family history for type 2 diabetes mellitus. Fifteen children (9%) were found to have Impaired Glucose Tolerance (IGT) while one child was frankly diabetic. Thirty-six children (23.4%) were diagnosed with a metabolic syndrome (MS). Systolic blood pressure was significantly correlated with BMI z score and with 2 hour glucose levels. Obese children with either hypertension or a family history of diabetes were significantly more likely to have glucose intolerance or metabolic syndrome (GI, OR= 4.7 ; MS, OR= 6.8)

CONCLUSIONS

A high percentage of obese children and adolescents develop metabolic complications. The percentage of children with such complications is greater when other risk factors such as hypertension and family history of type 2 diabetes are present. Family paediatricians play a fundamental role in the prevention, evaluation and treatment of child obesity. This study underscores the importance of performing routine evaluations of BMI and blood pressure in children aged 6-14 years, eventually by extending well-child visits to this age group.

Seroprevalence of HHV8 in a cohort of HIV-negative and HIV-positive patients in Mozambique

Kaposi Sarcoma shows several different clinical and epidemiological patterns. In Sub-Saharan Africa, where the HIV achieves an high prevalence of infection, the KS can be found both in HIV positive than in HIV negative patients, and the diffusion of the HHV8 virus is endemic. The aim of the work is to evaluate the HHV8 seroprevalence in Mozambique. Moreover the relationship of some main indicators, as CD4 and CD8 cells count, HIV viral load, Body Mass Index and haemoglobin values have been calculated in a part of the DREAM Cohort, (HIV positive patients enrolled in the Community of Sant'Egidio program to fight AIDS in the Sub-Saharan Africa). In the HIV positive cohort HHV8 negative and HHV8 positive groups show statistical significance (p < 0.05) in CD4 cells count, a strong significance (p = 0.01) in CD8 cells count and a significance also in Haemoglobin levels (p = 0.35). The difference in Haemoglobin levels (0.5 g/dl) is related more to a statistical than a clinical significance. The study confirms the free circulation of the HHV8 virus in the Mozambican population, with a prevalence rate of 51.1%, similar than that measured in bordering countries. Considering the CD8 value within the HIV positive sub-cohort a strong correlation with the positivity for HHV8 and the immunological status is suggested.

[A child health promotion intervention in Albania: results and lessons learned]

Albania is a Balkan country in South-Eastern Europe which, in recent years, has undergone complex demographic, political and economical changes. A notable drop in infant and maternal mortality rates and a significant rise in economic indicators have been observed in recent years. Despite this, over 15% of the population living in the northern and north-eastern areas of the country lives in extreme poverty conditions. In recent years various healthcare system reforms have been introduced, including the introduction of private healthcare and improvement of the main hospital infrastructures but not much has been done to increase the provision of essential healthcare services especially in rural and poor areas. Inequalities in health care are therefore widespread and these particularly affect children living in critical areas. In this paper we describe a paediatric healthcare intervention programme conducted in Albania from 2002 to 2004, aimed at improving the health and nutrition status of children and tackling healthcare system inequalities. The intervention consisted in offering free healthcare services and assistance, delivered through the Albanian healthcare system, to 5280 children. It also involved a health education programme for the mothers. The impact of the programme on the prevalence of infant malnutrition was evaluated by examining the medical records of 1745 infants followed for at least 6 months. Prevalence of malnutrition significantly decreased, from 13.4% to 4.2% during the study period. Mortality in children aged 0-5 years also showed a considerable drop. These results confirm that an efficient and sustainable model of paediatric healthcare assistance in Albania is possible.
