Determinants of weight, psychological status, food contemplation and lifestyle changes in patients with obesity during the COVID-19 lockdown: a nationwide survey using multiple correspondence analysis.

INTRODUCTION: The corona virus disease 2019 (COVID-19) pandemic forced most of the Italian population into lockdown from 11 March to 18 May 2020. A nationwide survey of Italian Clinical Nutrition and Dietetic Services (Obesity Centers or OCs) was carried out to assess the impact of lockdown restrictions on the physical and mental wellbeing of patients with obesity (PWO) who had follow-up appointments postponed due to lockdown restrictions and to compare determinants of weight gain before and after the pandemic. METHODS: We designed a structured 77-item questionnaire covering employment status, diet, physical activity and psychological aspects, that was disseminated through follow-up calls and online between 2 May and 25 June 2020. Data were analyzed by multiple correspondence analysis (MCA) and multiple linear regression. RESULTS: A total of 1,232 PWO from 26 OCs completed the questionnaires (72% female, mean age 50.2 ± 14.2 years; mean BMI 34.7 ± 7.6 kg/m2; 41% obesity class II to III). During the lockdown, 48.8% gained, 27.1% lost, while the remainder (24.1%) maintained their weight. The mean weight change was +2.3 ± 4.8 kg (in weight gainers: +4.0 ± 2.4 kg; +4.2% ± 5.4%). Approximately 37% of participants experienced increased emotional difficulties, mostly fear and dissatisfaction. Sixty-one percent reduced their physical activity (PA) and 55% experienced a change in sleep quality/quantity. The lack of online contact (37.5%) with the OC during lockdown strongly correlated with weight gain (p < 0.001). Using MCA, two main clusters were identified: those with unchanged or even improved lifestyles during lockdown (Cluster 1) and those with worse lifestyles during the same time (Cluster 2). The latter includes unemployed people experiencing depression, boredom, dissatisfaction and increased food contemplation and weight gain. Within Cluster 2, homemakers reported gaining weight and experiencing anger due to home confinement. CONCLUSIONS: Among Italian PWO, work status, emotional dysregulation, and lack of online communication with OCs were determinants of weight gain during the lockdown period.

Bronchial hyperresponsiveness in adults with seasonal and perennial rhinitis: is there a link for asthma and rhinitis?

Epidemiological studies have shown that asthma and rhinitis often coexist in the same patients and the prevalence of asthma is greater in patients with rhinitis. The aim of this study was to evaluate the differences in bronchial reactivity in subjects with seasonal and perennial rhinitis. We enrolled 128 subjects with seasonal or perennial allergic rhinitis divided into three groups: A with perennial rhinitis and allergy to Dermatophagoides Pteronissynus; B with seasonal rhinitis and allergy to Graminae and Parietaria, who underwent methacholine challenge test (MCHt) during the exposure period (fron March until May); C with seasonal rhinitis and allergy to Graminae and Parietaria, who underwent MCHt during the non exposure period (from June until February). The PC20 mean values of group A (1774.8 ± 20.7) and group B (1740.7 ± 38.8) were not significantly different, but significantly lower than those of group C (3010.0 ± 56.9) (p=0.001). The subjects with group A were positive to the MCHt in 54.54%, against 29.28% of group B and 11.62% of group C (p=0.007). The results show differences in the degree of bronchial responsiveness. The dose-response curves documented a lower value of PC20 in the group with perennial rhinitis and a statistically significant difference of bronchial hyperresponsiveness prevalence between the three groups (p=0.007).

Zafirlukast versus budesonide on bronchial reactivity in subjects with mild-persistent asthma.

Asthma is one of the most common chronic diseases in children and adults. Recent studies have shown that in asthmatic patients treated with inhaled corticosteroids there is a better disease’s control when adding a second drug, than increasing the corticosteroid’s dose. The aim of this study has been to evaluate the effectiveness and tolerance of zafirlukast, a leukotriene receptor antagonist, versus budesonide in clinically steady patients with mild persistent bronchial asthma. We have enrolled 36 subjects non smokers, with mild persistent bronchial asthma and 12 healthy subjects as control group. At the beginning of this study and at the end of the treatment (8 weeks), all patients underwent complete clinical work-up, pulmonary function testing (FEV1, PEF and FVC) and methacholine challenge test. The patients were divided into 3 groups: group A) 20 mg of zafirlukast twice a day; group B) 400 mg of budesonide twice a day; group C) 20 mg of zafirlukast twice a day and 400 mg of budesonide twice a day. Basal FEV1 and PEF presented no significant statistical differences between control subjects and patients of group A, B and C. After eight weeks there were no significant changes for FEV1 and PEF among the three groups. After therapy a strong significant increase of PD20 was documented in group A (p<0.005), group B (p<0.001) and group C (p<0.005), respect to baseline values. The antileukotriene drugs could be taken as an alternative drug, or in association with low-dose inhaled corticosteroids, in patients with mild persistent asthma, both for their clinical effectiveness and their easy ingestion, which is confirmed in compliance studies on inhaled steroids.
