“…65 One way that stakeholders have significantly improved quality of care for people with diseases related to obesity (eg, diabetes, dyslipidaemia, hypertension, cardiovascular disease) is by shifting treatment paradigms to be more patient-centred, focusing on each patient's preferences, values and needs. 2,3,9,[68][69][70][71] While there are several accurate and informative models of obesity that have been developed by leading experts and medical societies, 17,18,22,[72][73][74] truly patient-centric models are lacking.

A call to action to inform patient‐centred approaches to obesity management: Development of a disease‐illness model

Patient‐centred care is an essential component of high‐quality health care, shown to improve clinical outcomes and patient satisfaction, and reduce costs. While there are several authoritative models of obesity pathophysiology and treatment algorithms, a truly patient‐centred model is lacking. We describe the development of a patient‐centric obesity model. A disease‐illness framework was selected because it emphasizes each patient's unique experience while capturing biomedical aspects of the disease. Model input was obtained from an accumulation of research including contributions from experts in obesity and patient‐reported outcomes, qualitative research with adults living in the United States, and two targeted literature searches. The model places the patient with obesity at its core and links pathologic imbalances of energy intake and expenditure to environmental, sociodemographic, psychological, behavioural, physiological and medical health determinants. It highlights relationships between obesity signs and symptoms, comorbid conditions, impacts on health‐related quality of life, and some barriers to obesity management that must be considered to attain better outcomes. Providers need to evaluate patients holistically, understand what changes each patient is motivated to make, and recognize what challenges might impede weight reduction, improvements in comorbid conditions, signs and symptoms, and health‐related quality of life before pursuing individualized treatment goals. Patients living with obesity who do lose weight perceive benefits beyond weight loss. Ideally, this model will increase awareness of the complex, heterogeneous impacts of obesity on patients' well‐being and recognition of obesity as a chronic disease, and prompt a call to action among stakeholders to improve quality of care.

“…Hill et al [8] modeled happiness of persons by an ε-SIS infection over a social contact network. In a similar vein, obesity is known to have a self-infected component and its spread has been described [9,10] by an ε-SIS type of infection on social networks. The self-infection nodal process can also be considered as a "drift field" [11] that drives the infection in each node with the same strength.…”

Explosive phase transition in susceptible-infected-susceptible epidemics with arbitrary small but nonzero self-infection rate

The ε-susceptible-infected-susceptible (SIS) epidemic model on a graph adds an independent, Poisson selfinfection process with rate ε to the "classical" Markovian SIS process. The steady state in the classical SIS process (with ε = 0) on any finite graph is the absorbing or overall-healthy state, in which the virus is eradicated from the network. We report that there always exists a phase transition around τ ε c = O(ε − 1 N−1) in the ε-SIS process on the complete graph K N with N nodes, above which the effective infection rate τ > τ ε c causes the average steady-state fraction of infected nodes to approach that of the mean-field approximation, no matter how small, but not zero, the self-infection rate ε is. For τ < τ ε c and small ε, the network is almost overall healthy. The observation was found by mathematical analysis on the complete graph K N , but we claim that the phase transition of explosive type may also occur in any other finite graph. We thus conclude that the overall-healthy state of the classical Markovian SIS model is unstable in the ε-SIS process and, hence, unlikely to exist in reality, where "background" infection ε > 0 is imminent.

“…(1) Obesity is a multifactorial condition that can be related to nutritional alteration, genetic, psychological and socioeconomic factors, and sedentary lifestyle. (2) Obesity is classified by the body mass index (BMI), with intervals between 30 and 34.9 kg/m 2 considered as obesity class I; 35 to 39.9 kg/m2 considered as obesity class II; and ≥ 40 kg/m 2 considered as obesity class III also called as morbid obesity. (3,4) With the increased prevalence of obese people with BMI>50 kg/m 2 , it was necessary to broaden this classification, considering intervals between 50 and 60 kg/m 2 as super obese, and > 60 kg/m 2 as super-super obese.…”

RESUMO Objetivo avaliar os diferentes componentes da resistência do sistema respiratório e a força muscular respiratória, bem como investigar a ocorrência de limitação de fluxo expiratório (LFE) de pacientes obesos mórbidos (OM) na posição sentada. Métodos a amostra foi composta de OM (IMC ≥ 40 kg/m2) e de indivíduos não obesos (NO) com IMC entre 18 e 30 kg/m2. O protocolo foi composto de: avaliação antropométrica e da função respiratória (espirometria, pressões inspiratória (PIM) e expiratória máximas (PEM) e oscilometria de impulso). Na comparação entre os grupos, foi utilizado o teste T para amostras não pareadas. As correlações foram avaliadas pelo teste de Pearson, e o nível de significância foi de 5%. Resultados Foram avaliados 50 OM (idade 40,0 ± 10,4 anos, 1,64 ± 0,09 m, 138,8 ± 33,6 kg e 50,7 ± 8,9 kg/m2), além de 30 NO (idade 37,6 ± 11,5 anos, 1,67 ± 0,09 m, 65,2 ± 10,3 kg e 23,2 ± 22 kg/m2). Os OM apresentaram maiores valores de resistência total, central, de vias aéreas, tecidual e periférica quando comparados aos NO. Nenhum paciente apresentou LFE. A circunferência abdominal se associou com variáveis espirométricas PIM e PEM. A relação cintura-quadril se correlacionou com variáveis de mecânica respiratória, além das espirométricas PIM e PEM. Conclusões pacientes com obesidade mórbida e sem padrão espirométrico obstrutivo apresentam aumento nas resistências total, de vias aéreas, periférica e tecidual do sistema respiratório quando comparados a não obesos. Esses indivíduos, entretanto, não apresentam limitação de fluxo expiratório e redução da força muscular respiratória.
