Rolled Surface

To ensure the competitiveness of rolled metal in the modern market, the decisive factor is the quality of the rolled surface (defects with a depth of no more than 0.2 mm are allowed without stripping). Rolling processing is a source of formation of small surface defects, most of which are obtained in the process of deformation of a continuously cast billet (hereinafter referred to as CCB, billet) at hot rolling mills in the presence of areas with non-removed furnace scale. This is the main reason for the formation of such types of surface defects as rolled scale, ripple, scale shells, which reduces the quality of the rolled surface and increases the sorting of metal with surface defects. In addition, the scale not removed from the surface of the CCB has a negative impact not only on the quality of metal products, but also on the operation of rolling equipment.One of the directions that allows to achieve high quality of the surface of long products in production conditions is the effective removal of scale from the surface of the initial billet before hot deformation. Scale removal from the surface of the workpiece is carried out on the installation of a hydraulic descaling unit, but not always a satisfactory (complete) scale removal occurs.To determine the cause of poor – quality scale removal before hot deformation, the efficiency of the hydraulic descaling unit and the state of the metal – scale interface surface were investigated.

Factors Associated

An online survey was conducted to identify factors associated with financial insecurity, food insecurity and poor quality of daily lives of adults in Nigeria during the first wave of the COVID-19 pandemic. The associations between the outcome (experience of financial loss, changes in food intake and impact of the pandemic on daily lives) and the explanatory (age, sex, education level, anxiety, depression, HIV status) variables were determined using logistic regression analysis. Of the 4439 respondents, 2487 (56.0%) were financially insecure, 907 (20.4%) decreased food intake and 4029 (90.8%) had their daily life negatively impacted. Males (AOR:0.84), people who felt depressed (AOR:0.62) and people living with HIV -PLHIV- (AOR:0.70) had significantly lower odds of financial insecurity. Older respondents (AOR:1.01) had significantly higher odds of financial insecurity. Those depressed (AOR:0.62) and PLHIV (AOR:0.55) had significantly lower odds of reporting decreased food intake. Respondents who felt anxious (AOR:0.07), depressed (AOR: 0.48) and who were PLHIV (AOR:0.68) had significantly lower odds of reporting a negative impact of the pandemic on their daily lives. We concluded the study findings may reflect a complex relationship between financial insecurity, food insecurity, poor quality of life, mental health, and socioeconomic status of adults living in Nigeria during the COVID-19 pandemic.

Abstract Background Erectile dysfunction (ED) has a negative impact on ones’ relationships with poor quality of life as inevitable result. The effects of ED maybe worse in developing countries setting like Tanzania because men’s sexual health has been forgotten. Men’s sexual and reproductive health needs are not in the national reproductive health strategic. This study aimed to determine the prevalence and factors associated with erectile dysfunction among adult men in Moshi municipality, northern Tanzania. Results The mean age of the 381 men was 39.6 (SD ±16.8) years. The overall prevalence of ED on this study was 29.7%. The severity of ED among study participants was; 13.4% (51), 9.7% (37), 3.7% (14), 2.9% (11) had mild, mild to moderate, moderate and severe erectile dysfunction respectively. Age 40–54 years (Adjusted OR 5.0, 95% CI 2.5–9.9), > 55 years (aOR 11.7, 95% CI 5.8–23.7) and hypertension (aOR 2.6, 95% CI 1.1–6.4) were independent predictors of ED respectively. Conclusion The prevalence of ED is high among men in Moshi municipal as 1 out of 3 men have ED. Age and hypertension were independent predictors of ED. These results point to the need of community awareness and education programs to raise awareness among men about existence of ED problem, its consequence and where they can get advice and care in this setting. Further, health providers taking care of hypertensive and men with DM should be equipped with knowledge and skills on early detection for ED and how to counsel and where to refer patients for help.

Leprosy (Hansen’s disease) can affect multiple organs and body structures. Skin signs are typically observed in the early phase of the disease, hence being the first identifiable signs to propel clinical suspicion. Leprosy predominantly affects the skin and peripheral nerves. The disease has been documented many centuries preceding the biblical era. Over many decades, the classification of Hansen’s disease has changed as modern medical science evolved. Patients with leprosy are usually subjected to discrimination, rejection from society and can suffer from social stigma, poor quality of life (QoL), low self-esteem and permanent disfigurements. Studies have shown that leprosy has a significant negative impact on the patients’ QoL. Leprosy is often not suspected by practicing clinicians because it is no longer emphasised in the medical curricula. In modern years, attention has gradually shifted from leprosy to tuberculosis (TB) and human immunodeficiency virus (HIV).

SummaryAnxiety has reported prevalence rates between 38 and 72% among people with dementia. It has a negative impact on cognitive impairment and is associated with agitation and poor quality of life. The presence of excessive anxiety can be difficult to establish in people with dementia, especially when expressive or receptive speech is impaired. Unfortunately, there is a lack of research on the treatment of anxiety in dementia, and also on the wider issue of the management of anxiety disorders in old age. We explore the prevalence, presentation and diagnosis of anxiety in dementia and discuss the therapeutic options available.

Abstract Background Patients with adrenal insufficiency (AI) are treated with glucocorticoid replacement therapy (GRT). Although current glucocorticoid regimens aim to mimic the physiological circadian rhythm of cortisol secretion, temporary phases of hypo- and hypercortisolism are common undesired effects which lead to a variety of consequences like increased cardiovascular risk and premature mortality. Additionally, poor quality of life (QoL) and impaired sleep have been reported. However, little is known about these topics regarding the effects of daily dosage, duration of therapy, and patients with different forms of AI (primary, PAI, and secondary, SAI). Methods In this study, 40 adults with AI substituted with hydrocortisone (HC) and 20 matched healthy controls completed questionnaires evaluating depressive symptoms, subjective health status, quality of sleep and daytime sleepiness. Furthermore, demographic data, dosage of HC, duration of therapy and co-medication were evaluated. Patients were compared in different groups. Results Patients assessed general health significantly worse than controls; likewise, daytime sleepiness was reported significantly more often. Depressive symptoms differed significantly in the two groups but did not reach clinically relevant scores. There was no difference between patients with PAI and SAI. High dosage of hydrocortisone had negative impact on mental health but not on sleep quality or daytime sleepiness. Conclusions The present data highlight that poor QoL and impaired sleep are still severe and underrated issues in current GRT and might be additional factors for premature mortality in patients with AI. Some AI patients reach normal or near-normal self-assessed QoL and sleep, even despite unphysiological replacement.

Background: The poor knowledge and understanding of menstruation may lead to unsafe hygienic practice that in turn increases the risk of reproductive and genito-urinary tract infections and leads to overall poor quality of life. The food we consume have a complementary relationship with the pattern of menstrual cycle and so is the involvement of exercises. The study focused on understanding the relationship between effect of diet, exercise and other contributing factors on menstruation.Methods: The study was a prospective observational study done with a sample size of 650 subjects of 9 to 18 age group in whom menstruation already occurred who were recruited from five different schools in regions of Pathanamthitta and Alappuzha.Results: It was found that lack of exercise before and during menstruation has caused increased cramps and mood instability in girls. As well as skipping of breakfast and consumption of junk food was found to elevate pain, eventually affecting daily activities.Conclusions: The importance of counselling to all girls from the age of 9 was found to be necessary through the study and thereby adequate changes for a healthy future. Lack of exercise, unhealthy food habits and delayed identification of menstrual problems can have a negative impact on health.

Participants who had to recall 12 childhood events (a difficult task) were more likely to infer that they could not remember large parts of their childhood than participants who had to recall 4 events (an easy task), although the former recalled three times as many events. This pattern of results suggests that memory judgments are based on the experienced ease or difficulty of recall. Accordingly, the negative impact of recalling 12 events was attenuated when participants were led to attribute the experienced difficulty to the task rather than to the poor quality of their memory. The findings emphasize the role of subjective experiences and attribution in metamemory judgments.

It has been suggested that oral mucosa diseases related to stress have a negative impact on the quality of life. However, the information regarding which aspects are the most affected is inconclusive. The objective was to compare the quality of life associated with oral health in two groups: Cases formed by 21 patients coming from a teaching clinic, suffering oral lichen planus, recurrent aphthous stomatitis, and burning mouth syndrome; Control formed by 42 healthy subjects matched for age and gender. Oral Health Impact Profile questionnaire was applied. Statistical analysis showed that group Cases has worse quality of life (p 0.03) than the one of controls, specifically on psychological discomfort (p 0.027), physical disability (p 0.004); and handicap dimensions (p 0.002; RM 5.63 IC1.58-20.80). It was concluded that patients suffering oral mucosa disease related to stress showed poor quality of life.

Theoretical Approaches

Background: Sensory processing has been described as the ability to register, modulate, and organize sensory information to respond to environmental demands. Different theoretical approaches have studied the differential characteristics of sensory processing, such as Dunn’s model. From this framework, high sensitivity in sensory processing has been described as responses to stimuli from environment quite often due to a rapid activation of the central nervous system. It should be noted that the association between high sensitivity in sensory processing and health outcomes obtained in different studies are not homogeneous, so it is necessary to develop a review of this research in order to clarify the relationship between sensory processing and quality of life. Methods: We conducted a systematic review of the relevant studies using the PubMed, ScienceDirect, Scopus, and ProQuest databases to assess how sensory processing patterns are related to quality of life. Results: Fourteen studies concerning sensory processing and quality of life were included in the review. Some studies indicate negative, moderate, and significant correlations between these variables in which high sensitivity is related to a poor quality of life in the population studied. Conclusions: High sensitivity in sensory processing could have a negative impact on quality of life, thereby facilitating a fluctuation in well-being, daily functioning, and health.

Haematopoietic Cell

The severe acute respiratory syndrome coronavirus 2, which causes COVID-19, has now spread to many countries, has forced health care systems to minimise or even suspend access to specialist services for many patients because of social distancing policies. As a result of this, many patients are not in direct, face-to-face contact with their health care specialist. This can pose a challenge, since patients who have undergone haematopoietic cell transplant can suffer from an array of complications involving various organs in the body, such as inactivity-related deconditioning and fatigue, resulting in poor quality of life. These vulnerable patients must receive continuous and individualised rehabilitation guidance to help prevent deterioration and promote optimal functioning. This paper highlights the potential challenges for patients who have had haematopoietic cell transplant in the circumstances surrounding COVID-19 and proposes service development ideas to help reduce the negative impact on patients' quality of life.
