Use of nutritional food labels and consumers confidence in label information / Uso da rotulagem nutricional e percepção sobre a confiabilidade das informações por consumidores

ABSTRACT Objective This investigation evaluated the use of food labels and consumers' perception of the reliability of food labels nutritional information. Methods This is a transversal exploratory quantitative investigation, carried out in Curitiba, Brazil. A total of 536 students from a public institution participated in the survey answering a structured questionnaire. Descriptive analyses, Chi-Square test and Fisher's exact test were performed considering a significance level of 5%. Results The participants' mean age was 21.11±2.83 years, and 59.3% were female. It was noticed that 41.6% of consumers used the nutritional information sometimes and 14.7% always, mainly because they liked to know what they were buying and consuming (35.8%). Lack of patience (29.5%) and concern about the composition of the food purchased (34.2%) were the main reasons for not using the information provided. The most commonly used nutrition claim was "trans fat-free" (42.5%) and the type of food in which nutrition labeling was used most was milk and dairy products (42.0%). Frequent use of nutritional information was higher among women (p<0.01) and among those who practice physical activity (p=0.04). Many individuals relied on food labels nutritional information (61.9%), but out of these, 43.6% did not use that information at the time of purchase. There was no difference between respondents' confidence in the information, sociodemographic and health data. Conclusion Many people still do not use the label nutrition information. Efforts should be made to change this scenario. Changes in nutrition labeling can help modify this situation, with the use of clearer label information, more easily understood, that does not raise any doubts in the consumers' mind.

RESUMO Objetivo Este estudo avaliou o uso da rotulagem nutricional e a percepção sobre a confiabilidade das informações por consumidores. Métodos Pesquisa transversal, exploratória e de abordagem quantitativa, realizada no município de Curitiba, Brasil. Participaram 536 estudantes, de uma instituição pública, respondendo um questionário estruturado. Foram realizadas análises descritivas, teste Qui-Quadrado e teste exato de Fisher, considerando nível de significância de 5%. Resultados A idade média dos participantes foi 21,11±2,83 anos, sendo 59,3% do sexo feminino. Quanto ao uso das informações nutricionais, 41,6% utilizavam às vezes e 14,7% sempre, principalmente porque gostavam de saber o que estavam comprando e consumindo (35,8%). A falta de paciência (29,5%) e de preocupação com a composição do alimento comprado (34,2%) foram os principais motivos pelos quais não utilizarem as informações. A alegação nutricional mais utilizada foi "sem gordura trans" (42,5%) e o tipo de alimento em que mais se utilizou a rotulagem nutricional foi leite e derivados (42,0%). O uso frequente das informações nutricionais foi maior entre as mulheres (p<0,01) e os praticantes de atividade física (p=0,04). Muitos indivíduos confiavam nas informações presentes nos rótulos dos alimentos (61,9%), porém, destes, 43,6% não as utilizavam no momento da compra. Não foram observadas diferenças entre a confiança das informações, os dados sociodemográficos ou de saúde dos entrevistados. Conclusão Muitas pessoas ainda não usam as informações nutricionais, sendo necessário esforços para mudar este panorama. Alterações na rotulagem nutricional podem mudar este processo, com o uso de informações mais claras, de fácil entendimento, que não gerem dúvida ao consumidor.

Deslocamento espontâneo do núcleo do cristalino para câmara anterior / Spontaneous dislocation of the lens nucleus to the anterior chamber

Resumo Ruptura espontânea da cápsula anterior do cristalino, evoluindo com deslocamento anterior do núcleo é uma complicação rara da catarata hipermadura. Relatamos o caso de uma paciente do sexo feminino, 79 anos, que se apresentou com ruptura espontânea da cápsula anterior do cristalino com deslocamento anterior do núcleo em olho direito sem histórico de trauma ocular. O diagnóstico foi confirmado pela visualização das abas da cápsula anterior, principalmente quando o núcleo foi removido. Realizamos facoemulsificação do núcleo pelo risco de descompensar a córnea. É importante destacar a raridade do caso, sendo o primeiro relatado no Brasil.

Abstract Spontaneous rupture of the anterior lens capsule, evolving with anterior dislocation of the lens nucleus is a rare complication of hypermature cataract. We report a case of a female patient, 79 years old, who presented with spontaneous rupture of the anterior lens capsule with anterior dislocation of the nucleus in the right eye with no history of ocular trauma. The diagnosis was confirmed by the visualization of the tabs of the anterior capsule, especially when the nucleus was removed. We perform phacoemulsification of the nucleus by the risk of decompensating the cornea. It is important to highlight the rarity of the case, the first being reported in Brazil.

Applying Joint Mobilization at Different Cervical Vertebral Levels does not Influence Immediate Pain Reduction in Patients with Chronic Neck Pain: A Randomized Clinical Trial.

The aim of the present study was to compare the effects of applying joint mobilization at symptomatic and asymptomatic cervical levels in patients with chronic nonspecific neck pain. Forty-eight patients aged between 18 and 65 years and presenting nonspecific neck pain with a minimum duration of 3 months were recruited for the study. Included patients were randomized to one of two treatment groups: (i) control group: the most symptomatic vertebral level was mobilized; (ii) experimental group: a randomly selected vertebral level was chosen and mobilized. All patients received one treatment session. Pain intensity in resting position during the most painful active cervical movement as well as during vertebral palpation was quantified using an 11-point pain scale. Follow-up measures were taken immediately after intervention by a blinded assessor. The results showed no significant difference in pain intensity immediately after treatment between groups (symptomatic level treated vs. randomly chosen cervical vertebral level treated) during resting position, painful active movement, or vertebral palpation. Within-group comparisons showed significant pain relief after treatment during the most painful active movement as well as during vertebral palpation for both groups, but not during resting position. Significant change in immediate pain intensity during painful active movement and vertebral palpation was achieved after vertebral mobilization. however, both groups presented similar pain reductions suggesting that pain reduction due to joint mobilization is not specific to the vertebral level being mobilized.
