Malondialdehyde levels and bioaccessibility in healthy diet bars: A gastrointestinal digestion model.

Malondialdehyde (MDA), which is composed when n-6 and n-3 PUFAs are peroxidized, has been utilized as an indicator of lipid peroxidation and has been considered neurotoxic, cytotoxic, and mutagenic. This study aimed to determine the bioaccessibility level of MDA in diet bars sold as healthy snacks in the market using in vitro gastrointestinal digestive model. In our study, 28 different diet bar samples were bought from markets in Istanbul. MDA contents of the products were determined by the HPLC-FLD method. The investigation showed that diet bars had an average MDA concentration of 116.25 µg/100 g before digestion, while the average MDA concentration was 90.50 µg/100 g after in vitro digestion. In line with these data, the average MDA bioaccessibility of 28 diet bar samples was calculated as 77.3%. For this reason, more studies are needed to understand the relationship between both the MDA content and the reaction and nutritional components.

Hyperbaric oxygen treatment in delayed post-hypoxic encephalopathy following inhalation of liquefied petroleum gas: a case report.

Delayed post-hypoxic encephalopathy can occur after an episode of anoxia or hypoxia. Symptoms include apathy, confusion, and neurological deficits. We describe a 47-year-old male patient who inhaled gas from a kitchen stove liquid petroleum gas cylinder. He was diagnosed with hypoxic ischaemic encephalopathy 12 hours after his emergency department admission. He received six sessions of hyperbaric oxygen treatment (HBOT) and was discharged in a healthy state after six days. Fifteen days later, he experienced weakness, loss of appetite, forgetfulness, depression, balance problems, and inability to perform self-care. One week later, he developed urinary and fecal incontinence and was diagnosed with post-hypoxic encephalopathy. After 45 days from the onset of symptoms, he was referred to the Underwater and Hyperbaric Medicine Department for HBOT. The patient exhibited poor self-care and slow speech rate, as well as ataxic gait and dysdiadochokinesia. Hyperbaric oxygen was administered for twenty-four sessions, which significantly improved the patient's neurological status with only hypoesthesia in the left hand remaining at the end of treatment. Hyperbaric oxygen has been reported as successful in treating some cases of delayed neurological sequelae following CO intoxication. It is possible that HBO therapy may also be effective in delayed post-hypoxic encephalopathy from other causes. This may be achieved through mechanisms such as transfer of functional mitochondria to the injury site, remyelination of damaged neurons, angiogenesis and neurogenesis, production of anti-inflammatory cytokines, and balancing of inflammatory and anti-inflammatory cytokines.

Analysis of the cardiovascular effects of hyperbaric oxygen therapy in diabetic patients.

During hyperbaric oxygen (HBO2) therapy in humans, there are changes in cardiovascular physiology due to high pressure and hyperoxygenation. Peripheral vasoconstriction, bradycardia, and a decrease in cardiac output are observed during HBO2 therapy. These physiological effects of HBO2 therapy on the cardiovascular system are tolerated in healthy people. However, patients with underlying cardiac disease may experience severe problems during HBO2 therapy, such as pulmonary edema and death. In addition, cardiac complications may occur in patients with diabetes mellitus (DM). Therefore, HBO2 therapy may negatively affect cardiovascular physiology in patients with DM. The present study aimed to examine the cardiovascular effects of HBO2 therapy in diabetic patients. The findings of NT-ProBNP, troponin I, and electrocardiography (ECG) of diabetic patients who applied to the Ministry of Health University Gülhane Training Research Underwater and Hyperbaric Medicine Clinic were compared before and after the first HBO2 therapy session. When ECG findings were analyzed at the end of a session of HBO2 exposure, a statistically significant increase was observed in the QTc and QTc dispersion measurements (p≺0.001 and p = 0.02, respectively). In cardiac enzymes, there was a statistically significant increase in troponin I values after an HBO2 therapy session, but no statistically significant change was observed in Pro-BNP (p = 0.009, p = 0.3, respectively). Short-term exposure to HBO2 therapy had statistically significant changes in troponin I, QT, and QTc in patients with DM, which did not reach clinical significance. Despite very little evidence of cardiac dysfunction, we recommend caution in using HBO2 therapy in patients with DM and emphasize the need for further investigation of these measurements.

Does diving deteriorate hearing functions?

Studies evaluating the hearing function of professional divers have yielded mixed results. In this study, we aimed to observe the effect of diving on hearing function by comparing the audiometry of experienced divers with a non-diver control group. Secondly, we aimed to compare the hearing function among divers according to the diving years and the number of dives in terms of diving exposure. Experienced divers who applied to the University of Health Sciences Gulhane Training and Research Hospital Underwater and Hyperbaric Medicine Department between 2017-2021 for periodic fitness to dive examinations were included in our study. The control group was randomly selected from the non-diver population with similar ages and gender. The audiometry of the control group and the study group was compared. While the control group was found to be better only at 8,000 Hz in the left ear (p = 0.03), there was no difference between the study group and the control group in other frequencies and pure-tone averages. In conclusion, we did not find any evidence regarding the worsening effect of diving on the hearing functions of experienced divers. With the increased awareness of occupational safety in recent years, modern technologies, protective measures, and more conservative diving profiles may have minimized the possible adverse effects of diving on hearing function. Longitudinal studies on hearing functions in the same occupational diver groups should be conducted while observing the effect of different diving profiles and noise exposures.

The effect of auditory stimuli on the pain and physiological parameters of children on mechanical ventilation during aspiration procedure: A randomized controlled trial.

PURPOSE: The study was conducted to determine the effect of mother's voice and music sound on pain and physiological parameters during aspiration procedure in children with mechanical ventilation support in the pediatric intensive care unit. DESIGN AND METHODS: This study was a randomized controlled type experimental study. According to the power analysis result of the sample of the study, 84 children who were treated in the pediatric intensive care unit of two university hospitals in Istanbul were formed. Introductory Information Form, Ramsey Sedation Scale, Physiological Parameter Form and Face, Legs, Activity, Cry, Consolability (FLACC) Pain Scale were used to collect data. RESULTS: When the pain results of the children were evaluated, the mean FLACC Pain Scale value of the children in the control group was found to be significantly higher than children in the mother's voice and music voice group (p < 0.05). It was determined that the lowest FLACC Pain Scale value was in the mother's voice group (p < 0.05). When the physical parameter results were evaluated, it was determined that the physiological measurement values of the children in the experimental group were positively affected (p < 0.05), there was a significant difference between the control group (p < 0.05) and the most effective result was in the mother's voice group (p < 0.05). PRACTICE IMPLICATIONS: Allowing children to listen mother's voice and music during aspiration procedure reduces pain of the children, positively affects their physical parameter values and enhances quality of nursing care. The results of this study create a scientific basis for nursing practices in the clinical settings and contribute to the clinical practices by shedding a light on future evidence-based studies.

Oleuropein exhibits anticarcinogen effects against gastric cancer cell lines.

BACKGROUND: Oleuropein (OLE), the main phenolic compound of the olive fruit and leaves, has many heathful effects. Gastric cancer is the most fatal malignancy in many parts of the world and it is generally related to harmful dietetic factors. The anticarcinogenic role of OLE in gastric cancer has not been studied sufficiently yet. In this study, we aimed to research the cytotoxic, genotoxic and apoptotic effects of OLE on gastric adenocancer (AGS) cells in vitro. METHODS AND RESULTS: A standard cell line derived from gastric adeno cancer (AGS) cells was employed, and its performance following a 24-hour exposure to OLE at various doses was examined. The ATP cell viability assay, 2',7'-dichlorodihydrofluorescein-diacetate assay (H2DCF-DA) and alkaline single cell gel electrophoresis assay (Comet Assay) were used to study the cytotoxicity, production of reactive oxygen species (ROS) and genotoxicity respectively. The induction of apoptosis was discovered using flow cytometry. OLE reduced AGS cells viability about 60% at maximum concentration (500 µmol/L) and also resulted in approximately 100% DNA damage and about 40% apoptosis with necrosis in AGS cells depending on the increased doses. Cell viability was also significantly decreased in relation to increased intracellular reactive oxygen species (ROS) levels (p < 0.05 - 0.001). CONCLUSIONS: Oleuropein has shown significant anticarcinogen effects against gastric adenocancer (AGS) cells in vitro. Oleuropein, a nutrient rich in olive and olive oil, seems to be both protective and therapeutic against gastric cancer and may be a new chemotherapeutic agent in the future.

Hemiplegia resulting from acute carbon monoxide poisoning.

Carbon monoxide (CO) poisoning can cause neurological complications such as movement disorders and cognitive impairment through hypoxic brain damage. Although peripheral neuropathy of the lower extremities is a known complication of CO poisoning, hemiplegia is very rare. In our case, a patient who developed left hemiplegia due to acute CO poisoning received early hyperbaric oxygen treatment (HBOT). The patient had left hemiplegia and anisocoria at the beginning of HBOT. Her Glasgow coma score was 8. A total of five sessions of HBOT at 243.2 kPa for 120 minutes were provided. At the end of the 5th session, the patient's hemiplegia and anisocoria were completely resolved. Her Glasgow coma score was 15. After nine months of follow-up, she continues to live independently with no sequelae, including delayed neurological sequelae. Clinicians should be aware that CO poisoning can (rarely) present with hemiplegia.

Evaluation of forensic cases presented to the pediatric emergency department.

OBJECTIVE: Child forensic cases constitute an essential part of emergency presentations. The most crucial point is that the correct planning of protective and preventive activities depends on the correct analysis of the problem; therefore, there is a need for studies on childhood forensic cases. This study aimed to obtain data on the etiological characteristics of forensic cases presented to the pediatric emergency department. We believe that the collected data will guide the social measures in preventing forensic cases. METHODS: This retrospective study consists of forensic cases aged from 1 month to 18 years and presented to the pediatric emergency service of Adana City Training and Research Hospital between January 1, 2018, and December 31, 2019. The general forensic examination report of the cases was surveyed. RESULTS: For this study, 6577 general forensic examination reports were surveyed. 40% of the patients were females, and 60% were males. Traffic accidents were the most common (35.1%) cause of the emergency presentation, which was followed by assault (16.5%), fall from height (9.2%), accidental drug-caustic corrosive substance intake (7.8%), early pregnancy (7.4%), blunt or sharp force injuries (6.3%), electrical burn injuries (5.7%), suicide (5.1%), carbon monoxide-food poisoning (2.7%), and others that consisted of work accident, firearm injury, substance ingestion, suffocation, animal attack, sudden death, and missing child (4.2%). CONCLUSIONS: This most extensive study with 6577 cases has several important implications. First of all, traffic accidents continue to be an important public health problem today. Second, cases presented to the emergency department due to assault and blunt or sharp force injuries constitute an important part of forensic cases, and children who are driven to violence and crime in childhood are a situation that requires immediate action. Our third yet most important result is that early pregnancy is a much ignored social problem despite its importance.

Liver Stiffness Is Markedly Decreased After Chronic Hepatitis C Treatment.

AIM: The aim of the study was to demonstrate the liver stiffness (LS) change in chronic hepatitis C (CHC) patients obtained by elastography point quantification technique in before and after antiviral treatment (AVT). MATERIAL AND METHODS: This prospective study included 84 patients diagnosed with CHC who had not previously received treatment for CHC and who had an indication for using direct-acting AVT. Necessary measurements were recorded with noninvasive liver fibrosis (LF) examinations. Posttreatment control of patients was carried out (ombitasvir + paritaprevir + ritonavir) + 3 months after the start of treatment for those treated with dasabuvir and 6 months after the start of treatment for patients treated with sofosbuvir + ribavirin. Liver stiffness changed after AVT is accepted as (Δ-LS), LS before AVT-LS after AVT. RESULTS: Basal LS was found to decrease significantly after AVT (8.00 ± 2.56 kPa vs 6.95 ± 2.86 kPa, P < 0.05). Similar aspartate aminotransferase-to-platelet ratio index and platelet number fibrosis 4 indices were observed before and after AVT (P > 0.05). It was observed that Δ-LS value after AVT was lower in patients with Child-Pugh class A cirrhosis than patients without cirrhosis (P < 0.05). In the comparison between Δ-LS value after AVT and LF score determined by liver biopsy, it was seen that the greatest Δ-LS value was in patients with fibrosis score of 3. An independent relationship was found between Δ-LS after AVT and LF score determined by biopsy (P < 0.05). CONCLUSIONS: The LS value determined by the elastography point quantification technique is more effective than other noninvasive laboratory methods in demonstrating the CHC treatment response in clinical practice.

The changes in pulmonary functions in occupational divers: smoking, diving experience, occupational group effects.

BACKGROUND: Diving challenges the respiratory system because of the pressure changes, breathing gases, and cardiovascular effects. We aimed to analyse the long term effect of occupational diving on pulmonary functions in terms of diving experience (year), smoking history, and occupational groups (commercial divers and SCUBA instructors). MATERIALS AND METHODS: We retrospectively analysed respiratory system examination results of the experienced occupational divers who were admitted to the Undersea and Hyperbaric Medicine Department for periodic medical examination between January 1, 2013 and February 28, 2019. RESULTS: Sixty-four divers applied to our department. Candidate divers were not included in our study. The mean diving experience (year) was 13.6 ± 7.3. None of the divers complained of pulmonary symptoms. Pulmonary auscultation and chest radiography were normal in all cases. In divers with 20 years or more experience, the FEV1/FVC ratio and FEF25-75(%) was significantly lower (p < 0.001, p < 0.05, respectively). In addition, there was a statistically significant negative correlation between FEV1/FVC ratio and FEF25-75(%) and diving experience (year) (p < 0.05, r = -0.444, p < 0.05, r = -0.300, respectively). As the diving experience increase per 1 year, the FEF25-75(%) value decreases by 1.04% according to linear regression analyses. However, smoking and occupational groups did not show any significant influence on pulmonary function test parameters. CONCLUSIONS: Occupational diving seems to create clinically asymptomatic pulmonary function test changes related to small airway obstruction after long years of exposure.

Novel thiazolidinone-containing compounds, without the well-known sulphonamide zinc-binding group acting as human carbonic anhydrase IX inhibitors.

A small collection of 26 structurally novel thiazolidinone-containing compounds, without the well-known sulphonamide zinc-binding group, were synthesised and tested in enzyme inhibition assays against the tumour-associated hCA IX enzyme. Inhibition constants in the lower micromolar region (KI < 25 µM) have been measured for 17 of the 26 compounds. Even though the KI values are relatively weak, the fact that they do not contain a sulphonamide moiety suggests that these compounds do not interact with the active site zinc ion. Therefore, docking studies and molecular dynamics simulations have been performed to suggest binding poses for these structurally novel inhibitors.

Health-related quality of life assessed by LupusQoL questionnaire and SF-36 in Turkish patients with systemic lupus erythematosus.

The LupusQoL is a disease-specific health-related quality of life (HRQoL) measure for patients with lupus. We conducted this study to compare the efficiency of LupusQoL-TR (validated Turkish version of the LupusQoL questionnaire) with the 36-item Short-Form Health Survey (SF-36), a generic quality of life (QoL) scale, in Turkish patients with lupus. Both questionnaires were conducted at a single visit to the clinic. Disease activity was measured with the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). Associations between the LupusQoL-TR and SF-36 domains were examined while also examining age, disease duration, and disease activity for each questionnaire. Descriptive statistics, Spearman's correlation coefficients, and Students t test were performed to analyze the data. A total of 113 consecutive patients with lupus (F/M 108:5, mean age 40.6 ± 11.9 years, mean disease duration 8.5 ± 7.0 years) were included, and 69 % of these were active. The median SLEDAI score was 2 (0-24), the mean global LupusQoL-TR score was 60.9 ± 23.3, and the mean SF-36 score was 41.2 ± 9.0. There was a significant correlation between LupusQoL-TR and SF-36 mean scores (r = 0.83; p < 0.001). QoL assessed by LupusQoL-TR and SF-36 did not correlate with disease activity (r = -0.11; p = 0.244 and r = -0.03; p = 0.721, respectively). LupusQoL-TR and SF-36 questionnaires were beneficial instruments in evaluating HRQoL in Turkish lupus patients. However, LupusQoL-TR and SF-36 were not associated with SLEDAI scores, which suggested that QoL might be affected by other factors besides disease activity, especially in clinically inactive or mildly active patients.

Anxiety and depression predict quality of life in Turkish patients with systemic lupus erythematosus.

OBJECTIVES: The aim of our study was to evaluate quality of life (QoL) in patients with systemic lupus erythematosus (SLE) and assess the impact of disease activity and psychological distress on health-related quality of life (HRQoL) in Turkey. METHODS: The Medical Outcomes Study Short Form (SF) -36 was used in a cohort of 113 consecutive patients with SLE and 123 age- and gender-matched healthy subjects to measure HRQoL. Patients' disease activity was assessed with SLE disease activity index (SLEDAI) and psychological distress was evaluated by the Hospital Anxiety and Depression Scale (HADS) for all participants. Patients' demographic and clinical data were recorded at the time of HRQoL and HADS testing. Multiple logistic regression analysis was performed to explore the relationships between demographics, disease duration, disease activity as well as psychological (anxiety and depression) variables and the HRQoL. RESULTS: SLE patients have lower quality of life than healthy controls. No relationship between HRQoL and SLE activity or disease duration were observed. Patients with anxiety and/or depression reported worse SF-36 scores than those without psychological distress. The results of multivariate analysis suggested that HADS-A, HADS-D scores and working status were associated with the impairment of HRQoL. CONCLUSIONS: HRQoL is impaired in patients with SLE and is associated with mood disorders. Physicians should pay close attention to detect anxiety and depression and manage them in order to improve the quality of life in patients with SLE.
