Noncompliance to iodine supplementation recommendation is a risk factor for iodine insufficiency in Portuguese pregnant women: results from the IoMum cohort

PURPOSE

After a recommendation for iodine supplementation in pregnancy has been issued in 2013 in Portugal, there were no studies covering iodine status in pregnancy in the country. The aim of this study was to assess iodine status in pregnant women in Porto region and its association with iodine supplementation.

METHODS

A cross-sectional study was conducted at Centro Hospitalar Universitário São João, Porto, from April 2018 to April 2019. Pregnant women attending the 1st trimester ultrasound scan were invited to participate. Exclusion criteria were levothyroxine use, gestational age < 10 and ≥ 14 weeks, non-evolutive pregnancy at recruitment and non-signing of informed consent. Urinary iodine concentration (UIC) was measured in random spot urine by inductively coupled plasma-mass spectrometry.

RESULTS

Median UIC was 104 μg/L (IQR 62-189) in the overall population (n = 481) of which 19% had UIC < 50 µg/L. Forty three percent (n = 206) were not taking an iodine-containing supplement (ICS) and median UIC values were 146 µg/L (IQR 81-260) and 74 µg/L (IQR 42-113) in ICS users and non-users, respectively (p < 0.001). Not using an ICS was an independent risk factor for iodine insufficiency [adjusted OR (95% CI) = 6.00 (2.74, 13.16); p < 0.001]. Iodised salt use was associated with increased median iodine-to-creatinine ratio (p < 0.014).

CONCLUSIONS

A low compliance to iodine supplementation recommendation in pregnancy accounted for a mild-to-moderately iodine deficiency. Our results evidence the need to support iodine supplementation among pregnant women in countries with low household coverage of iodised salt.

Defeitos congênitos em uma região de mineração de carvão

OBJETIVO: Avaliar a relação entre o impacto ambiental decorrente da extração de carvão e sua repercussão na saúde reprodutiva de uma população, residente em pequenas cidades do Sul do Brasil, pela observação da freqüência de defeitos congênitos nos recém-nascidos. MÉTODOS: Foram monitoradas as freqüências de oito defeitos congênitos em 10.391 nascidos vivos, ocorridos no período de janeiro de 1985 a dezembro de 1995 em um hospital localizado no município de São Jerônimo, RS. Destes, foram selecionados oito maiores defeitos congênitos, e a análise de suas prevalências ao nascimento visou reduzir os possíveis erros-diagnósticos. As taxas de defeitos congênitos foram comparadas às de outros hospitais geograficamente próximos e às fornecidas pelo Estudo Colaborativo Latino-Americano de Malformações Congênitas (ECLAMC) para a América Latina. RESULTADOS/CONCLUSÕES: As freqüências observadas não diferiram das encontradas em hospitais regionais e no ECLAMC. O pequeno número de crianças avaliadas mostra apenas algumas tendências, concluindo serem necessários outros estudos mais profundos.

[The home caregiver in Betim/MG]

This is a qualitative study about the care provided by "caregivers" enrolled in the Home Care Program in Betim, Minas Gerais. Interviews were held during home visits in order to identify characteristics of home care providers, analyze their perception about health care, verify factors which interfere in home care and relationships which are established between caregiver/person cared for/other family members. Discourse analysis (Fiorin, 1993) was used to build the empirical categories which revealed that most of the caregivers are family members, women, average age of 42 years, limited schooling, mostly housewives. The subjects sampled reported that the act of caring involves technique, duty and dedication. They referred to financial difficulties, physical and emotional stress. The relationships established during care involved feelings of pleasure, satisfaction and helplessness in the face of the needs and sufferings of the person cared for. The authors concluded that home care fosters more humane care, but requires technical guidance and emotional training for the caregivers and support from the health institution.

[Reception: possibility of reorganizing nursing care]

The study analyzes reception as a strategy for reorganizing nursing care, identifying its presuppotions and mechanisms which make it possible to implement and qualifying potentialities of care. It uses the qualitive approach, giving priority to primary sources: questionnaires answered by managers, degree nurses, nursing auxilliares and doctors from the Municipal Health Office of Belo Horizonte. It was found that the nursing auxiliary is the main person carrying out this activity, followed by the degree nurse. The main activities are listening, screening and forwarding, with little focus on guidance. The actors emphasize team integration and the understanding of the work process as facilitating factors. The training and qualification of professionals was considered as one of the mechanisms to overcome difficulties. It reveals the failures of the structure of service for reception. The conclusion is that this practice suggests the need for the reorganization of the nursing work process in order to improve the quality of health care.

A genetic diagnostic survey in a population of 202 mentally retarded institutionalized patients in the south of Brazil

The Associação dos Pais e Amigos dos Excepcionais (APAE) is an institution for mentally retarded patients located at Caxias do Sul in the south of Brazil. A genetic diagnostic survey of 202 individuals from this institution is presented. The patients had a male:female ratio of 1.3:1 and their ages varied from 1 month to 47 years with a mean of 5.5 years. Using personal and family data, careful clinical examination and laboratory investigation, the authors established a definitive diagnosis in 132 patients (65.34%). A constitutional disorder was present in 111 patients (54.95%). Down's syndrome patients represented 32.15%, while 1.98% had other chromosomal anomalies. In 25 patients (12.37%) a disorder of Mendelian inheritance was diagnosed. In 8 patients (3.96%) a multiple congenital anomalies/mental retardation (MCA/MR) syndrome was recorded. Eight patients (3.96%) had a central nervous system (CNS) malformation. An acquired condition was observed in 21 patients (10.39%), including pre- or post-natal infections. In the remaining 70 patients (34.65%) a conclusive diagnosis was not possible.
