It has long been recognized that albumin has prognostic value in patients with cancer. However, although the Global Leadership Initiative on Malnutrition GLIM criteria (based on five diagnostic criteria, three phenotypic criteria and two etiologic criteria) recognize inflammation as an important etiologic factor in malnutrition, there are limited data regarding the association between albumin, nutritional risk, body composition and systemic inflammation, and whether albumin is associated with mortality independent of these parameters. The aim of this study was to examine the relationship between albumin, nutritional risk, body composition, systemic inflammation, and outcomes in patients with colorectal cancer (CRC). A retrospective cohort study (n = 795) was carried out in which patients were divided into normal and hypoalbuminaemic groups (albumin < 35 g/L) in the presence and absence of a systemic inflammatory response C-reactive protein (CRP > 10 and <10 mg/L, respectively). Post-operative complications, severity of complications and mortality were considered as outcome measures. Categorical variables were analyzed using Chi-square test χ2 or linear-by-linear association. Survival data were analyzed using univariate and multivariate Cox regression. In the presence of a systemic inflammatory response, hypoalbuminemia was directly associated with Malnutrition Universal Screening Tool MUST (p < 0.001) and inversely associated with Body Mass Index BMI (p < 0.001), subcutaneous adiposity (p < 0.01), visceral obesity (p < 0.01), skeletal muscle index (p < 0.001) and skeletal muscle density (p < 0.001). There was no significant association between hypoalbuminemia and either the presence of complications or their severity. In the absence of a systemic inflammatory response (n = 589), hypoalbuminemia was directly associated with MUST (p < 0.05) and inversely associated with BMI (p < 0.01), subcutaneous adiposity (p < 0.05), visceral adiposity (p < 0.05), skeletal muscle index (p < 0.01) and skeletal muscle density (p < 0.001). Hypoalbuminemia was, independently of inflammatory markers, associated with poorer cancer-specific and overall survival (both p < 0.001). The results suggest that hypoalbuminemia in patients with CRC reflects both increased nutritional risk and greater systemic inflammatory response and was independently associated with poorer survival in patients with CRC.

Rice ranks second among cereals in dietary uses around the world. Rice is deficient in iron (Fe), and these are important micronutrients for infants, men, and women. Fortification of rice with iron would help to minimize nutrient deficiency disorders among humans. The current study aims to introduce nutrient-rich rice. The effects of iron on germination, growth, photosynthetic pigment, antioxidant activity, and reduction of oxidative stress were investigated in four Oryza sativa L. cultivars. O. sativa of four different cultivars (Basmati-515, PK-386, KSK-133, and Basmati-198) were grown under five treatments (100, 200, 300, 400, and 500 mM) of iron sulphate (FeSO4) in soil of pH 7.5, along with control, by using six replicates. The result revealed that Fe treatment significantly affected seed germination percentage, plant growth parameters, biomass, photosynthetic pigments (chl a, chl b, total chlorophyll, and carotenoids), antioxidant enzymatic and non-enzymatic activity, and reduced oxidative stress. The findings also showed that Fe application reduced the oxidative stress including malondialdehyde content and hydrogen peroxide, by increasing the antioxidant enzymatic activity, i.e., catalase, ascorbate peroxidase, superoxide dismutase, peroxidase, glutathione peroxidase, 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH), and non-enzymatic antioxidant compounds (proline, amino acid, total soluble protein, phenolics, flavonoids, reducing-non-reducing sugar, and carbohydrates) in all cultivars of O. sativa. Furthermore, FeSO4 induced a significant increase in proline, free amino acid, and total carbohydrates in the leaves of all O. sativa cultivars, but Basmati-198 showed the significantly highest content by 169, 88, and 110%, respectively, at concentration of 500 mM. The present research work showed that soil application of FeSO4 improved the seed germination, plant growth, and antioxidants enzymatic and non-enzymatic activity, denatured the ROS (reactive oxygen species) in alkaline soil. In order to understand the underlying mechanisms, long-term field investigations should be carried out at the molecular level to examine patterns of iron uptake and plant growth.

There is increasing evidence that an increased BMI is associated with increased complications after surgery for colorectal cancer (CRC). However, the basis of this relationship is not clear. Since men and women have different fat distribution, with men more likely to have excess visceral fat in BMI defined obesity, there may be a sex difference in the surgical site infection (SSIs) rate in the obese. Therefore, the aim of this study was to examine the relationship between sex, BMI, clinic-pathological characteristics and the development of postoperative infective complications after surgery for CRC and to establish whether there were gender differences in complication following surgery for CRC. Data were recorded prospectively for patients undergoing potentially curative surgery for CRC in a single centre between 1997 and 2016. Patient characteristics were recorded and complications were classified as either infective or non-infective. The relationship between sex, BMI, associated clinicopathological characteristics and presences of complications were examined by Chi-square test for linear association and multivariate binary logistic regression model. A total of 1039 patients were included. There were significant differences in the presence of complications between male and female (p ≤ 0.001), the rate of complication was higher in obese male (44%); in particular SSIs, wound infection and anastomotic leak (p ≤ 0.05). The rate of surgical site infection was 12% in male patients with normal BMI compared with 26% in those with a BMI ≥30 (p ≤ 0.001), while the rate of SSIs in female patients was 10% in those with normal BMI and those with a BMI ≥30. In males, BMI remained significantly associated with SSI on multivariate analysis [(OR = 1.42, 95% CI 1.13-1.78) P = 0,002]. Obesity prior to surgery for CRC increases the risk of infective complications in both male and female. Increased BMI in male patients was associated greater risk of SSIs and wound infection compared to female patients. Male obese patients should be considered at high risk of developing post-operative infective complications.

Women’s health issues are complex and require collaborative efforts to unravel some of these complexities. This study aims to identify the incidence risk of Postpartum Depression (PPD) in a national sample of women in Saudi Arabia and the relationship with several health status, lifestyle, and sociodemographic factors. A cross-sectional study with an online questionnaire format assessed the risk of postpartum depression using the Edinburgh Postnatal Depression Scale (EPDS) and included several questions on postpartum health status and lifestyle factors. Of the 550 women who responded to the survey 75% scored within range of risk for PPD (≥12). We found significant associations between family income, younger baby age, birth difficulty, having family support, level of physical activity, and the risk for PPD (p < 0.05). Urgent attention and resources should be directed towards screening and treatment for PPD in the healthcare system. The development of programs for awareness, education, and support of postpartum mothers in the Kingdom of Saudi Arabia is also required.
