Raw materials and process parameters in bread production can modulate the glycemic index, which on itself has been linked with provision of better hunger satisfaction and maintaining better satiation. The objective of this research was to investigate if using unrefined wheat flour or the addition of intact cereals in formulation or alternating the baking time would have an effect on physical characteristics, sensory quality, glycaemic index and appetite sensations in wheat sourdough bread. In the study, three types of commercial part-baked frozen sourdough bread, baked to the final baking for two different times (long and short baking time) were used. A randomized controlled crossover trial was performed with 10 healthy adults who consumed sufficient quantity of bread to ingest 50 g available carbohydrates. Participants self-reported appetite sensations (desire to eat, hunger, fullness, satisfaction, appetite) on a 10 cm visual analog scale (VAS) scale in a course of 180 min. In addition, bread products were subjected to overall acceptability and different sensory attributes were examined on JAR "just about right" scale. Different bread formulations (refined flour, unrefined wheat flour, cereal flour or intact cereals) and different length of baking time significantly influenced ( < 0.005) physical, textural and sensory features of products. The alternation of aforementioned parameters decreased the glycemic index, but not significantly ( > 0.005). No correlation was found between lower GI, satiety and satiation. Liking score and incremental area under the curve (iAUC) of satiety and satiation were calculated as highest in sourdough bread with added cereals.

BACKGROUND
Picky eating might be associated with a higher risk of being underweight and poor growth. This study aimed to investigate if picky eaters aged between three and 12 years showed differences in height, weight, and body composition compared to their non-picky peers using a body impedance analysis (BIA).
METHODS
This cross-sectional study was conducted between March 1, 2022, and July 31, 2022, on children aged three to 12 years who presented to the outpatient pediatric clinics at Al Habib Ar Rayyan in Riyadh, Saudi Arabia. Body composition was measured using BIA after manually inserting the height, gender, and age into the machine, where body mass index (BMI), fat mass, and skeletal muscle mass were recorded. Participants were classified as under/normal/over for each body composition measurement.
RESULTS
A total of 2234 children were entered into the final data analysis. Our analysis showed that 1917 (85.8%) were Saudis and 1117 (50%) were males. The mean age of participants was 6.08±2.01 years and 1151 (51.5%) were in the pre-school age. The reported prevalence of picky eaters was 1684 (75.4%), of whom, 606 (27.0%) were selective eaters, 365 (16.2%) were low appetite eaters, and 723 (32.2%) were both selective and low appetite eaters. Being underweight was significantly more common among the picky eaters 487 (28.9%) compared to those non-picky eaters 55 (10.0%) (p<0.001). Significantly, 1280 (76%) picky eaters had below-average skeletal muscle mass compared to 151 non-picky eaters (27.5%) (p<0.001). The low appetite picky eater group had more under skeletal muscle mass children 277 (75.9%) compared to the selective picky eater group 412 (68.0%) (p=0.009). Additionally, the low appetite group possessed lower muscle ratios (p=0.012) and were more underweight than the selective group (p<0.001). Furthermore, the low appetite group showed a higher percentage of children below the 3rd percentile in the height for age category (p=0.003) compared to the selective group.
CONCLUSION
This study is the first of its kind in Saudi and globally to evaluate body composition using BIA among children. The study showed that picky eating is more associated with underweight children and low muscular mass. Despite the normal BMI, height, and weight of a picky eater, their skeletal muscle mass might be less than average, which could be associated with an increased risk of morbidity.

BACKGROUND AND OBJECTIVE
Pediatric COVID-19 epidemiology and factors associated with adverse outcomes - , are largely unstudied. We described the clinico-demographic characteristics of Filipino pediatric COVID-19 patients and determined the factors associated with adverse outcomes.
METHODS
This is a retrospective cohort study of 180 hospitalized SARS-CoV-2-confirmed cases 0-18 years old from April 2020 to August 2021 in a tertiary COVID-19 referral hospital in Manila, National Capital Region. Crude associations were determined using chi-squared or Fisher's exact tests; and medians were compared using the Mann-Whitney test. Factors predictive of mortality were determined using Cox proportional hazards regression analysis. The survivor functions were depicted in graphs.
RESULTS
About 41.67% had mild disease, 58.33% were males, 39.4% aged 0-4 years, and 69.44% had at least one comorbidity. About 9.44% died (adjusted 9.2 persons per 1000 patient-days, 95% CI 5.5%-15.2%), 17.78% needed invasive mechanical ventilation, and 20% needed ICU admission. Independently, severe-critical COVID-19 (HRc 11.51, 95% CI 3.23, 41.06), retractions (HRc 10.30, 95% CI 3.27, 32.47), alar flaring (HRc 4.39, 95% CI 1.53, 12.58), cyanosis (HRc 4.39, 95% CI 1.72, 14.11), difficulty of breathing (HRc 7.99, 95% CI 2.25, 28.71), poor suck/appetite (HRc 4.46, 95% CI 1.59, 12.40), ferritin (HRc 1.01, 95% CI 1.00, 1.01), IL-6 (HRc 1.01, 95% CI 1.00, 1.01), aPTT (HRc 1.05, 95% CI 1.01, 1.10), IVIg (HRc 4.00, 95% CI 1.07, 14.92) and corticosteroid (HRc 6.01, 95% CI 2.04, 17.67) were significant hazards for mortality. In adjusted Cox analysis, only retractions (HRa 34.96, 95% CI 3.36, 363.79), seizure (HRa 9.98, 95% CI 1.76, 56.55), and corticosteroids (HRa 8.21, 95% CI 1.12, 60.38) were significantly associated with mortality while alar flaring appeared to be protective (HRa 0.10, 95% CI 0.01, 0.95). Several clinical characteristics were consistently associated with adverse outcomes.
CONCLUSIONS
Majority of hospitalized pediatric COVID-19 patients were very young, males, had mild disease, and had at least one comorbidity. Mortality, invasive mechanical ventilation, and ICU admission were relatively low. Except for alar flaring which appeared to be protective, retractions, seizure, and use of corticosteroids were associated with adverse outcomes.

BACKGROUND
Renal arteriovenous malformations (rAVMs) are congenital abnormal pathways between renal arteries and veins that are rare in the general population. It is often misdiagnosed as malignant renal tumors with abundant blood supply, and the definitive diagnosis primarily relies on angiography. Multimodality imaging, including contrast-enhanced computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET)/CT plays an important role in the differential diagnosis of renal space-occupying lesions.
CASE PRESENTATION
A 56-year-old man presented with abdominal distension, loss of appetite, and back pain without obvious cause 2 years ago, without nausea vomiting, or frequent urination. Gastroscopy and colonoscopy showed multiple polyps in the duodenum and colon. Abdomen contrast-enhanced CT revealed a mass of 1.6 × 1.4 cm in the left kidney, which was considered to be a malignant tumor. PET/CT was performed for further diagnosis; the F-fluorodesoxyglucose (F-FDG) PET/CT scan showed mild uptake in the left renal mass, while no uptake of F- prostate-specific membrane antigen (PSMA) was observed. Following a multidisciplinary discussion, the possibility of renal AVMs was considered and subsequently confirmed by renal angiography as the diagnosis. Then, selective segmental renal artery embolization was performed for treatment.
CONCLUSION
Renal AVMs are extremely rare in clinical practice. Due to limited research on the application of F-FDG and F-PSMA PET/CT to renal AVMs, its role remains largely unexplored. With the increasing popularity of PET/CT imaging, comprehensive imaging of the disease has become indispensable. We report the first case of PSMA PET/CT imaging in renal AVMs, and when PSMA expression is absent in a renal mass, the possibility of renal AVMs should be considered.

We report a case of a 44-year-old male patient, who presented to the University Hospital of Salzburg, Austria with abdominal pain, persistent jaundice, and lack of appetite. Radiological work-up (CT, MRI, PET/CT) indicated a suspicious mass of the uncinate process of the pancreatic head with adjacent infiltration and regional lymphadenopathy. The differential diagnosis was between primary pancreatic cancer and focal autoimmune pancreatitis. Further laparoscopic biopsies from multiple areas, showed only fibrous scarring processes, with no malignancy. Treatment with steroids didn't give any benefits. After multiple follow-up CTs and MRs within 6 months-additional biopsies were done, which eventually demonstrated adenocarcinoma. Evidently the cancer diagnosis was much delayed and the patient started receiving chemotherapy, but radical surgery was not possible. Multiple articles and case reports can be found in the literature, that are reviewing the fact that pancreatic inflammatory processes are mimicking pancreatic tumor, but not many articles or case reports are available in the literature, where neoplastic processes are misinterpreted as inflammatory and incorrectly proven with histological examination. One of the main reasons for improper diagnosis is the desmoplastic reaction around the pancreatic malignancy. Another important aspect is the acceptance of histological diagnosis as conclusive, where no opposing arguments are specified, based on radiological criteria.

Review
Dolutegravir is an integrase inhibitor and is recommended by the World Health Organization as the preferred first-line and second-line human immunodeficiency virus treatment in all populations. Excessive weight gain associated with dolutegravir-based regimens is an emerging issue; however, the long-term metabolic consequences of this effect have not been fully understood. Growing evidence shows that this leads to a higher incidence of hyperglycemia, hypertension, and metabolic syndrome, along with elevated cardiovascular risk. Dolutegravir-based regimens, also associated with greater adipocyte differentiation and greater expression of markers associated with lipid storage, continue to be a problem among patients living with human immunodeficiency virus. The mechanisms by which certain antiretroviral therapy agents differentially contribute to weight gain remain unknown. Some clinical investigators speculate that dolutegravir could interfere with central nervous system appetite regulation (melanocortin-4 receptor) and insulin signaling, or may have better penetration of adipose tissue where they could exert a direct impact on adipose tissue adipogenesis, fibrosis, and insulin resistance. This review summarizes our current understanding of weight gain and fat changes associated with dolutegravir and its possible secondary metabolic comorbidities.

In low- and middle-income countries, particularly in urban areas, adolescent diets consist mainly of energy-dense and nutrient-poor foods, putting them at risk of malnutrition and non-communicable diseases (NCD). In Bangladesh, little is known about the diet quality of adolescents, their food choices and the drivers of such choices. This study assessed motivations and ability to consume a healthy diet among adolescent girls and boys from low-income urban families and how these drivers were associated with dietary diversity and diet quality. A cross-sectional survey was conducted among 299 adolescents (15-19 years) from low-income households in Dhaka city during September-October 2020. The Diet Quality Questionnaire was used to collect non-quantitative food intake in the previous day or night to calculate diet quality indicators of food group diversity score, % of adolescents achieving minimum dietary diversity, NCD-Protect and NCD-Risk and the Global Dietary Recommendations score. Motivation was measured by 11 food choice motives. Ability was measured by belief in own ability to engage in healthy eating behaviors (self-efficacy). Adolescent diets showed a mean food group diversity of 4.9 out of 10, with 60% of adolescents achieving minimum dietary diversity, but lacked health-promoting foods (average of 2.7 out of 9 food groups) yet included few foods to avoid and limit (1.6 out of 9). Adolescents valued food choice motive 'safety' the most, followed by 'health', 'taste', 'price', 'convenience' and 'local or seasonal'. A higher motivation to consume 'local or seasonal' and a lower motivation driven by 'price', and a higher perceived self-efficacy were associated with better diet quality. Future interventions should address self-efficacy, concerns about food price and increase local and seasonal foods availability in the urban poor food environment of Dhaka to improve overall diet quality.

This mixed-methods cross-sectional study examines food consumption patterns, dietary diversity, and factors affecting food intake and malnutrition in the rural Mbale District in Eastern Uganda, during both wet and dry seasons. Participants (n=100; 66% females) completed a food frequency questionnaire identifying foods and beverages consumed in the preceding 12 months. Individual interviews (n=8) were conducted with key workers. Analysis of seventeen food items revealed seasonal variations in carbohydrate and protein sources. During the dry season, staples like matooke (mashed boiled plantains) and sweet and Irish potatoes were affected, while protein-rich foods such as beans and groundnuts saw increased consumption in the wet season. Fruit and vegetable intake also rose during the wet season. The main causes of malnutrition that emerged from the interviews were the lack of knowledge about food and nutrition, financial struggles, climate impact, and cultural beliefs. The last theme covered strategies to combat malnutrition. Although carbohydrate intake remains consistent throughout seasons due to reliance on posho (maize flour porridge) and cassava, variations in the number of meals and protein sources, particularly beans and groundnuts, were observed. Both of these, being the primary protein sources in rural households' diets, are highly susceptible to climate fluctuations. This may pose significant implications for food security, as heightened climate instability may impede their production. Solutions to combat malnutrition discussed by the interviewees include education, employment, family planning, and healthcare improvements. Professionals emphasise the need for comprehensive approaches to address these complex issues. In addition, data on food consumption during the dry and wet seasons should be collected as a difference in food consumption during the seasons may become more prominent with the need to implement tailored interventions.

Acute moderate- to high-intensity exercise, primarily aerobic exercise, has been reported to decrease food reward in brain regions via the hedonic pathways and reduce preference for high-energy or high-fat foods. However, studies examining food reward responses to acute exercise have been limited to measuring food reward only after exercise and less frequently before and after exercise. Therefore, the changes in food reward in response to acute exercise remain unclear. This study investigated the effect of acute running on food reward in healthy young men. Fourteen young healthy men (mean ± standard deviation, age; 23 ± 2 years, body mass index; 21 ± 2 kg/m) completed two trials (i.e., exercise and control) in a randomised, crossover design. Participants performed a 30-min running bout at 70% of maximal oxygen uptake or sitting rest before and after food reward evaluation with a computer-based food choice behaviour task tool. Food reward was assessed for foods varying in fat content and sweet taste, and there were four assessment parameters: explicit liking, explicit wanting, implicit wanting and frequency of choice of each food category (relative preference). Explicit and implicit wanting, and relative preference for high-fat relative to low-fat foods were reduced after the exercise trial compared to the control trial (trial-by-time interaction, all p ≤ 0.02). Implicit wanting and relative preference for sweet relative to savoury foods were increased after the exercise trial compared to the control trial (trial-by-time interaction, all p ≤ 0.003). These findings indicate that moderate-intensity acute running alters the reward bias away from high fat towards low fat foods and away from savoury towards sweet foods in healthy young men.

Stress-induced eating is associated with various health risks like obesity and cardiovascular disease, exacerbated by the overconsumption of unhealthy foods. This study sought to investigate replacement coping strategies for stress-induced eating that participants can seek to implement using behaviour change techniques like implementation intentions. The study adopted a feasibility and acceptability design, with 258 participants (88.37% female) aged 17-75 years old who self-reported stress-induced eating. Participants were asked to identify cues for their stress-induced eating and evaluate the acceptability of eight potential replacement coping strategies. After selecting their preferred strategy, participants formed implementation intentions, linking the strategy with their previously identified cues. There were six themes of cues for stress-induced eating as identified by participants, including a range of external and internal stressors. Themes regarding the acceptability of the replacement coping strategies were organised based on constructs from integrated social cognition theories. Participant responses reflected cognitive and affective attitudes, and control and normative beliefs behind engagement in coping behaviour; further, automatic and volitional processes were described by participants as playing a role in whether a coping strategy was deemed as useful. Plans formulated by participants commonly detailed specific situations and strategies to utilise, though few described start times or durations of their plan. Action planning was found to significantly increase following formation of implementation intentions, and participants' descriptions supported the feasibility and acceptability of utilising implementation intentions to adopt alternative coping strategies to stress-induced eating. Future research should conduct a randomised controlled trial to assess the efficacy of the implementation intentions intervention in promoting uptake of replacement coping strategies to reduce stress-induced eating.
