Comparative study on microwave and tray drying of beef: Effect of partial salt replacement on drying kinetics and structural characteristics
Olum, Emine; Candoğan, Kezban
Beef cuts were dried by tray drying (TD), microwave drying (MD), and TD+MD. Salting as pre-treatment was carried out with NaCl or NaCl+KCl salts to evaluate the effect of sodium reduction. The beef was divided into nine groups: three were subjected to TD, MD, and TD+MD; for the other six groups, dry salting was applied with 100% NaCl or 50% NaCl + 50% KCl, followed by MD, TD, or TD+MD. Processing times of TD, MD, and TD+MD were about 660, 250, and 300 min, and effective diffusivities (Deff) were 1.33 × 10−8, 3.88 × 10−8, and 3.57 × 10−8 m2/s, respectively. Compared with TD, the MD procedure resulted in significantly harder texture and lower rehydration ratio (p < 0.05). SEM images of dried beef indicated fractures and disruption after TD, while a compact structure was obtained with MD. Both salt types contributed a softer texture in rehydrated MD, but KCl did not change the hardness values of dried meat. MD could have great potential for drying meat by reducing drying time, and KCl could be applied as a substitute for NaCl without adversely affecting the structural quality.

Early atherosclerosis and conduction defect in a rare case of dunnigan type familial partial lipodystrophy

A 45-year-old female patient was admitted to the emergency department with syncope. Her medical history revealed a diagnosis of Familial Partial Lipodystrophy 2 (FPLD2). The patient's electrocardiogram showed a complete atrioventricular (A-V) block, and she had a history of insulin-dependent diabetes mellitus and coronary artery bypass surgery. A severe stenosis was observed in the aortic right coronary artery saphenous vein graft during coronary angiography, which was successfully revascularized. Subsequently, due to persistant syncope attacks, a permanent pacemaker was implanted after an electrophysiological study. This case highlights that serious cardiac conduction defects in patients with FPLD2 may not only be related to coronary artery disease but can also present as direct conduction defects.; Senkop şikayeti ile acil servise başvuran 45 yaşında kadın hastanın öyküsünden ailesel parsiyel lipodistrofi 2 (FPLD2) tanısı aldığı öğrenildi. İnsüline bağımlı diabetes mellitus ve koroner by-pass cerrahisi öyküsü olan hastanın elektrokardiyografisinde A-V tam blok izlendi. Koroner anjiyografide aort-sağ koroner arter safen ven greftinde ciddi darlık görülmesi nedeniyle başarılı revaskülarizasyon uygulandı. Sonrasında, senkop atakları devam eden hastaya yapılan elektrofizyolojik çalışma sonucunda kalıcı kalp pili takıldı. Bu olguda, FPLD2 tanısı olan hastalarda ciddi kardiyak iletim kusurlarının sadece koroner arter hastalığı ile ilişkili olmadığını, hastalığın doğrudan iletim kusurları ile de ortaya çıkabileceğini vurgulamak istedik.

Risk factors for pfannenstiel incisional hernia following cesarean delivery and outcomes after laparoscopic and open surgical repair
Sakoğlu, Nevin; Fırat, Aysun
Background: To analyse risk factors for cesarean section (CS)-induced incisional hernia in reproductive-aged women. Outcomes of minimal invasive herniorrhaphy and open technique were presented. Methods: Records of patients with Pfannenstiel hernia between 2010 and 2022 were reviewed. Risk factors for incisional hernia were evaluated with surgical outcomes. Results: 76 patients were included. Mean age was 46 ± 8.1 years. Bulging (81.5%), pain or discomfort (57.8%) and distention (31.5%) were the most common symptoms. We combined ultrasonography (90.7%) with contrasted tomography (71%) or magnetic resonance imaging (30%) for surgical planning. Risk factors were found as multiple previous CSs, local wound complications such as seroma, hematoma or abscess, body mass index >25, smoking, pregnancy-induced diabetes mellitus, emergency CS, and inadequate surgical technique (each, p < 0.05). In open technique (51.3%), fascia was closed by polydioxanone suture, with onlay mesh fixation. In laparoscopic hernioplasty (48.6%), tacker was used for mesh reinforcement. There was no bowel injury. Early complications were seroma and infection (p < 0.01 and p < 0.05, respectively). Most significant late complication was recurrence (7.8%). Conclusions: Clinicians should be ready to encounter more reproductive aged women with incisional hernia, since worldwide CS rate continues to rise. Awareness of risk factors, imaging methods, surgical options and outcomes are of great importance.

Evaluating the effect of daytime sleepiness and sleep quality on balance, fatigue and life quality of shift workers
Doǧan, Semanur; Aras Bayram, Gülay
BACKGROUND: Changes in the sleep-wake cycle in shift workers can cause many health problems. OBJECTIVE: The aim of this study was to investigate the relationship between daytime sleepiness and sleep quality on balance, physical activity level, fatigue and quality of life in shift and non-shift workers. METHOD: A total of 58 employees, 29 shifts and 29 non-shifts, were included in the study. Data were collected using the Epworth Sleepiness Scale, the Pittsburgh Sleep Quality Index, the Tandem Posture Test, the One-Foot Stand Test, the Ten-Step Tandem Walking Test, the International Physical Activity Questionnaire-Short Form, the Fatigue Severity Scale, and the Nottingham Health Profile. RESULTS: Individuals working in shifts had higher fatigue severity and daytime sleepiness levels (p < 0.05), while physical activity levels and sleep quality were lower than those working without shifts (p < 0.05). It was determined that as the daytime sleepiness of individuals working in shifts and non-shifts increased, their quality of life decreased (p < 0.05). CONCLUSION: According to the data obtained from the study, individuals working in shifts compared to individuals working without shifts experienced higher levels of daytime sleepiness and fatigue severity level while sleep quality and physical activity level were lower.
