Leprosy is a public health problem due to the physical disabilities and deformities it causes. This study aimed to describe new leprosy cases using an operational classification and analyzing spatial patterns by means of epidemiological and quality indicators of health services in Pernambuco State, Brazil, between 2005 and 2014. This was an ecological study performed in 184 municipalities grouped into 12 health regions units for analysis. To analyze spatial patterns, the Bayesian local empirical method and Moran's spatial autocorrelation indicator were applied and box and Moran maps were used. Individuals aged ≥15 years old, grade zero physical disability and complete remission as the treatment outcome were predominant in both paucibacillary and multibacillary cases, the only difference was the predominance of females (n=9,286; 63.00%) and males (n=8,564; 60.70%), respectively. These variables were correlated (p<0.05) with the operational classification. The overall detection rate showed three high-priority areas; the indicator rate of grade 2 physical disability revealed clusters in regions IV, V, and VI; and the indicator rate of cases with some degree of disability showed precarious municipalities in seven health regions. Pernambuco maintains an active chain of transmission and ongoing endemicity of leprosy. Therefore, spatial analysis methods allow the identification of priority areas for intervention, thereby supporting the disease elimination strategy.

Objectives: to describe the prevalence of congenital malformations in live births in Recife, based on the relationship of birth and infant death data. Methods: a cross-sectional study with data from the Live Birth Information System (Sinasc) and Mortality (MIS) of residents in Recife-PE between 2013 and 2015. The deterministic linkage of deaths and live births (LB) with malformation and the prevalence rate were calculated. Results: 545 (95.1%) deaths and live births were matched. According to the Sinasc, the prevalence of congenital malformations was 10.4 per 1,000 LB. After the linkage, the rate was 12.4. Malformations of the musculoskeletal system (42.1%) among live births were high-lighted, as well as malformations of the circulatory system (35.3%) found in infant deaths. Conclusions: linkage increased the prevalence of congenital malformations in the studied cohort. This demonstrates the potential of this strategy for the monitoring of congenital malformations, which can be used to monitor infant death.

Leprosy is a public health problem in South American, African and Oceanian countries. National programs need to be evaluated, and the survival analysis model can aid in the construction of new indicators. The aim of this study was to assess the period of time until the outcomes of interest for patients with or exposed to leprosy by means of survival analysis surveys. This review researched articles using the databases of PubMed, Science Direct, Scopus, Scielo and BVS published in English and Portuguese. Twenty-eight articles from Brazil, India, Bangladesh, the Philippines and Indonesia were included. The Kaplan–Meier method, which derives the log-rank test, and Cox’s proportional hazards regression, which obtains the hazard ratio, were applied. The mean follow-up until the following outcomes were: (I) leprosy (2.3 years) in the population who were exposed to it, (II) relapse (5.9 years), (III) clinical manifestations before, during and after treatment—nerve function impairment (5.2 years), leprosy reactions (4.9 years) and physical disability (8.3 years) in the population of patients with leprosy. Therefore, the use of survival analysis will enable the evaluation of national leprosy programs and assist in the decision-making process to face public health problems.

This study analyzed the association between individual and household factors and the incidence of trachoma among a population aged between 1 and 9 years in the state of Pernambuco. This was a population-based household study conducted using a population-based sample of residents from 96 census sectors of the 1778 sectors considered to be at social risk in the state. The estimated odds ratio of the univariate analysis presented a confidence interval of 95%. Weights and clusters were adjusted through the Generalized Linear and Latent Mixed Model (GLLAM) method. Trachoma cases were the dependent variable in the multivariate analysis. The independent variables were selected through the stepwise forward method, with an input criterion of 20% (p < 0.20) and an output criterion of 10% (p < 0.10). The prevalence was 6.65%. Trachoma was associated with a female sex, age of 5–9 years, either the absence of use or infrequent use of soap to wash the hands and face, the presence of nasal secretion, a lack of piped water from a public supply system, a greater number of rooms used for sleeping, a greater number of people living in the same household, and a family income of up to one minimum monthly wage. The prevalence of follicular trachoma in Pernambuco was higher than what is recommended by the World Health Organization (WHO).

To estimate the prevalence of cases of trachoma in the population at social risk aged 1-9 years in Pernambuco State and its mesoregions. This was a cross-sectional study in which secondary data from the National Household Survey on Trachoma (2014-2015) were analyzed. The study covered 96 census tracts distributed across the mesoregions of Pernambuco State (Metropolitan Region of Recife, Zona da Mata, Agreste, Sertao do Sao Francisco and Sertao Pernambucano). The study included all homes with children aged 1-9 years, and all of them were examined for trachoma, using the WHO criteria. Among the total of 7,423 children aged 1-9 years who participated in this survey, 446 presented with active trachoma. Thus, the prevalence of trachoma in Pernambuco State, in children between 1-9 years old was 6.65%, and it was higher among children aged 5-9 years (7.12%) and among girls (7.23%). This result was seen in the majority of the mesoregions studied, except in the Zona da Mata and Sertao do Sao Francisco, where there were higher prevalences in the age group of 1-4 years (5.55%) and among boys (5.90%). A tendency towards a higher prevalence between 1 and 6 years of age was observed. The follicular trachoma continues to be an important public health problem in Pernambuco State. It particularly affects poor people, including those living in urban areas of the State.

Spatial analysis of leprosy case distribution serves as a critical tool for identifying priority areas for intervention, particularly in settings with marked epidemiological heterogeneity. This study aimed to analyze the spatial distribution of new leprosy cases in Pernambuco, Brazil, 2000–2024. This is an ecological study with the municipalities of residence as the units of analysis. The data was extracted from the Notifiable Diseases Information System. The average incidence rates were calculated: general, in children under 15 years of age and with grade 2 physical disability at diagnosis, for four five-year periods. Bayesian smoothing and Moran’s global and local autocorrelation statistics were applied. The average rates of overall detection were 29.0/100,000 inhabitants per year (very high); in children under 15 years of age, 10.7/100,000 inhabitants per year (hyperendemic); and grade 2 physical disability, 1.6/100,000 inhabitants per year (low). Spatial analysis showed significant spatial heterogeneity, with clusters of high overall detection rates of leprosy cases, high detection rates among children under 15, and high rates of grade 2 physical disability at diagnosis, mainly in macro-regions I and IV. There is circulation of Mycobacterium leprae across all macro-regions of the state, with evidence of active transmission foci in macro-region III. Therefore, municipalities with a priority for intervention are concentrated in macro-regions I and IV, highlighting the need to strengthen leprosy surveillance and control actions in the state.
