Examining the Relationship Between Food Insecurity, Nutrition, and Chronic Disease Risk Factors: Implications for Public Health Interventions

Abstract

Food insecurity is a pressing public health issue that affects millions of individuals worldwide and is associated with poor nutrition and increased risk of chronic diseases. This review examines the relationship between food insecurity, nutrition, and chronic disease risk factors to inform public health interventions aimed at addressing this complex issue. We conducted a comprehensive literature review to synthesize current evidence on the pathways through which food insecurity influences dietary intake, nutritional status, and chronic disease risk factors.

Our findings highlight that food insecurity is associated with inadequate access to nutritious foods, leading to deficiencies in essential nutrients such as vitamins, minerals, and fiber. Individuals experiencing food insecurity are more likely to consume energy-dense, nutrient-poor foods, which can contribute to obesity, diabetes, cardiovascular disease, and other chronic conditions. Moreover, food insecurity is linked to disparities in diet quality, food access, and health outcomes across diverse populations, including children, elderly adults, racial and ethnic minorities, and low-income individuals.

“Innovations in Interventional Cardiology”

Abstract

Recent years have seen notable developments in the dynamic and quickly developing field of interventional cardiology within cardiovascular medicine. These advancements have not only changed the way cardiovascular diseases are diagnosed and treated, but they have also completely changed patient care, giving those who have heart problems new hope and prospects. We shall examine some of the most important developments in interventional cardiology in this essay, emphasizing their relevance and effects on clinical practice (Patel, 2017).
The creation and improvement of percutaneous coronary intervention (PCI) procedures is one of the most important advances in interventional cardiology. A catheter is inserted into the coronary arteries during PCI, sometimes referred to as angioplasty, to remove blockages and restore blood flow to the heart muscle. The advent of drug-eluting stents (DES) and bioresorbable scaffolds, among other advances in PCI technology over time, has significantly improved procedure success rates and long-term results for patients with coronary artery disease (CAD). Furthermore, more accurate lesion assessment and optimal stent insertion have been made possible by the use of intravascular imaging modalities including intravascular ultrasound (IVUS) and optical coherence tomography (OCT), which has increased the effectiveness of PCI treatments (Al-Lamee, 2018).

Lifestyle Adjustments and Cardiovascular Health Outcomes

Abstract

Cardiovascular health is crucial for overall well-being, with cardiovascular diseases (CVDs) posing a significant global burden. Lifestyle adjustments play a pivotal role in preventing and managing CVDs, addressing risk factors such as poor diet, physical inactivity, and chronic stress. Chronic stress, in particular, has been linked to adverse cardiovascular outcomes through physiological and behavioral mechanisms. Effective stress management techniques, including mindfulness, meditation, yoga, and relaxation exercises, offer promising strategies for improving cardiovascular health. Additionally, dietary modifications are integral to cardiovascular health, with heart-healthy diets emphasizing nutrient-rich foods and supporting weight management, blood pressure regulation, and inflammation reduction. Despite the benefits of lifestyle adjustments, individuals may face challenges such as lack of motivation, social influences, socioeconomic factors, and psychological barriers. Implementing behavioral change strategies, such as patient education, behavioral counseling, goal setting, social support, motivational interviewing, and feedback mechanisms, can facilitate the adoption and maintenance of healthier lifestyles, thereby reducing the risk of CVDs and enhancing overall cardiovascular well-being.

Using Branch and Bound Method to Solve Multiobjective Sequencing Problem

Abstract

This article offers a branch and bound (BAB) solution to the multi-objective composition minimization problem of three objectives of the total completion time (∑C_j), the total lateness (∑L_j) and maximum tardiness (T_max). Branch and bound (BAB) is an effective method to discover the optimal solution for composition multiple objective problems in disciplines of machine sequencing. The problem is difficult with just one machine.  A heuristic method which is shortest processing time rule was used to find the upper bound. Using the decomposition property of the multi-objective problem, that the lower bound provided by BAB. Based on the results of computer test examples, conclusions on the BAB method’s efficiency are taken into account. The BAB gives optimal solution for the problem in high quality.

Keywords: Multi-objective, sequencing, upper bound, lower bound, branch and bound method, machine, optimal solution.

Effectiveness of a Counseling Program based on Unified Protocol Therapy in Reducing Symptoms of Social Anxiety and Developing Social Competence among Divorced Women in Riyadh

Abstract

Divorced women often grapple with the feelings of anxiety, depression, and poor personal and social compatibility, as well as less opportunity for efficient social interaction, less satisfaction with life, and lower productivity at work. This study aimed to identify the effectiveness of a counseling program based on the Unified Protocol Therapy in reducing symptoms of social anxiety and developing social competence among divorced women in Riyadh (Saudi Arabia). To achieve the objectives of the study, a semi-experimental approach was used in a two-group design and the study sample consisted of (28) divorced women who were randomly distributed between two equivalent groups (experimental – control) with (14) women for each group. The Social Anxiety Scale, the social competence scale, and the counseling program based on the unified protocol were also used.

The study results showed that there were statistically significant differences between the mean scores of the experimental and control scores in the post application of the social anxiety scale in favor of the control group, and on the scale of social Competence of the total score of the scale and all its sub-dimensions in favor of the experimental group. The results also indicated that there were statistically significant differences between the mean scores of the experimental group members in the pre- and post-applications on the total score of the social anxiety scale in favor of the pre-application, and on the social Competence scale of the total score of the scale and all its sub-dimensions favoring the post-application. Finally, the results showed that there were no statistically significant differences between the mean scores of the experimental group members in the post and follow-up applications on the total score of the social anxiety scale and social competence.

In light of the study results, the importance of providing social and psychological services to divorced women can be emphasized, with recommendation of benefiting from this study program in training, qualifying and caring for divorced women, and to highlight the importance of joining preventive and curative programs.

Keywords: symptoms of social anxiety, social competence, Unified Protocol therapy, divorced women.

Surgical treatment for cataracts and the condition of dry eye

Abstract

Cataract surgery is one of the most common and successful ophthalmic procedures performed worldwide, offering significant improvements in visual acuity and quality of life for millions of individuals affected by cataracts. However, despite its efficacy, cataract surgery has been increasingly recognized as a potential precipitant or exacerbator of dry eye symptoms in a subset of patients (Davis, 2016).

Dry eye disease (DED) encompasses a range of illnesses that result in instability of the tear film, increased osmolarity, persistent inflammation, and abnormalities in the nerves responsible for sensation, all of which contribute to long-term dysfunction of the surface of the eye. Preexisting dry eye disease (DED) can create difficulties after cataract surgery, particularly when there is persistent inflammation, scarring, irregular eyelids, and reduced clarity of the eye’s internal structures. Additionally, it is recognized that this condition deteriorates after cataract surgery, resulting in an increased likelihood of complications and impaired visual results. The likely cause of this is an elevation in inflammation, toxicity resulting from eye drops that contain preservatives such as benzalkonium chloride (BAK), and damage to the nerves in the cornea caused by incisions made near the limbus. In addition, phacoemulsification alone has been documented to result in a decrease in tear film breakdown time, tear meniscus height, and corneal sensitivity after the surgery (Donthineni, et al.2020).
