Relationship between Occurrence and Progression of Lung Cancer and Nocturnal Intermittent Hypoxia, Apnea and Daytime Sleepiness

SummaryThe possible relationship between lung cancer and nocturnal intermittent hypoxia, apnea and daytime sleepiness, especially the possible relationship between the occurrence and progression of lung cancer and obstructive sleep apnea syndrome (OSAS) was explored. Forty-five cases of primary lung cancer suitable for surgical resection at the Third Affiliated Hospital of Kunming Medical University between January 2017 and December 2017 were recruited (lung cancer group), and there were 45 patients in the control group who had no significant differences in age, sex and other general data from lung cancer group. The analyzed covariates included general situation, snore score, the Epworth Sleeping Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), apnea and hypopneas index (AHI), oxygen desaturation index 4 (ODI4), lowest arterial oxygen saturation [LSpO2 (%)], oxygen below 90% of the time [T90% (min)], the percentage of the total recorded time spend below 90% oxygen saturation (TS90%), to explore the possible relationship between lung cancer and above indicators. The participants were followed up for one year. The results showed that: (1) There was significant difference in body mass index (BMI), ESS, AHI, T90% (min), TS90%, ODI4, snore score and LSpO2 (%) between lung cancer group and control group (P0.05); (2) Patients in the lung cancer group were divided into OSAS subgroup and non-OSAS subgroup according to the international standard for the diagnosis of OSAS. There was ...

ABSTRACT Objective Review the diet and nutritional status of women surviving breast cancer following the Dietary Guidelines for the Brazilian Population. Methods A cross-sectional study was conducted with 201 women, who underwent anthropometric measurements to determine body mass index, waist circumference and waist/hip ratio. Dietary assessment was performed usinga food frequency questionnaire. Consumption was stratifi ed into four groups: fresh/minimally processed food (Group 1), processed food ingredients (Group 2), processed food (Group 3) and ultra-processed food (Group 4).The ratio of daily contribution of each food ...

O’RourkeAbstractChimeric antigen receptor (CAR) T cells are a form of autologous immunotherapy that has changed the therapeutic landscape of hematologic malignancies. CAR T cell therapy involves collection of a patient’s T cells by apheresis, ex vivo genetic modification of the T cells to encode a synthetic receptor that binds a specific tumor antigen, and infusion of the T cells back into the patient. With the unprecedented success of CAR T cells in leukemia and lymphoma, a growing nu...

Retinoic acid is also important in postnatal life in the maintenance of tissue homeostasis, while retinoid-based therapies have long been used in the treatment of a variety of cancers and skin disorders. As the number of people living with chronic disorders continu...

Recently, people have paid more attention to its application in the treatment for cancers. Compared to normal cells, cancer cells maintain a higher level of reactive oxygen species (ROS) due to the dysfunctional oxidative phosphorylation and they highly rely on glucose for glycolysis and p...

Abstract The species Kalanchoe laciniata (L.) DC. and Bryophyllum pinnatum (Lam) Pers. are native from Brazil and Madagascar, respectively. Both belonging to the Crassulaceae family and being widely used by population as a natural anti-inflammatory agent. These species have similar leaf morphology and for this reason, they are known by the same popular name as “ sai ão ” or “ coirama ” . Several studies have been published involving different parts and preparations of these species. Therefore, this review aims to provide an update overview about the traditional uses, chemical constitution, ph...
