Can artificial intelligence predict COVID-19 mortality?

OBJECTIVE: COVID-19 infection rapidly spread across the globe and evolved into a pandemic. Artificial intelligence (AI) has been used to predict the spread of the virus and diagnose and treat the disease. In this study, we aimed to predict whether patients admitted to the intensive care unit (ICU) due to COVID-19 infection will result in mortality. PATIENTS AND METHODS: Ninety parameters were used for each 589 ICU patient. The nine parameters with the highest effect on mortality were determined. Four hundred seventy-one patients were used to train the AI with these nine parameters. AI was tested with 118 patient data. RESULTS: AI estimated mortality with 83% sensitivity, 84% specificity, 84% accuracy, and 0.81 F1 score. Therefore, the area under the curve was calculated as 0.91. The results indicate that mortality among COVID-19 patients admitted to the ICU can be predicted based on their laboratory parameters on the first day. CONCLUSIONS: These findings underscore the potential benefits of utilizing AI in managing pandemics.

Comparison of immunogenicity for Sinovac-CoronaVac vaccine vs. natural infection during cancer treatment.

OBJECTIVE: Efficacy of the COVID-19 vaccines in cancer patients, especially during their active treatment, are lacking. Most of the studies in the literature compared the immunity in cancer patients with a cross-sectional cohort or retrospectively. Our study investigated Sinovac-CoronaVac COVID-19 vaccine immunogenicity and compared it with natural COVID-19 disease in cancer patients during their cancer therapy. PATIENTS AND METHODS: A total of 111 patients with cancer and who are on active treatment were included in the study. This is a single-center study and was designed prospectively. Two group of patients were included in the study, natural disease and vaccinated group. RESULTS: A total of 111 patients were included in the study, 34 of whom had natural COVID-19 disease. Antibody levels following the first dose vaccine were 0.4 (0-1.9) U/ml while after the second dose of vaccine were 2.6 (1.0-7.25) U/ml. Immunogenicity levels were 82.4% in the natural disease group and 75.8% in the vaccinated group after the second shot of the vaccine. Immunogenicity rate was significantly higher in non-chemotherapy (receiving immunotehrapy/targeted therapy or biologic agent) group compared to chemotherapy drug (92.9% vs. 63.3%, p=0.004). There was a difference between the antibody levels following the first and second vaccination [median (IQR): 0.3 (0-1.0) and 3.3 (2.0-6.7), p=0.001, respectively]. CONCLUSIONS: The present study revealed that the Sinovac-CoronaVac vaccine showed an acceptable immunogenicity following two shots in cancer patients who were receiving active systemic therapy. On the other hand, natural disease immunogenicity was higher than vaccinated group.

The aggregate index of systemic inflammation may predict mortality in COVID-19 patients with chronic renal failure.

OBJECTIVE: Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), was first detected in December 2019 and then spread globally, resulting in a pandemic. Initially, it was unknown if chronic kidney disease (CKD) contributed to the mortality caused by COVID-19. The immunosuppression associated with this disease may minimize the COVID-19-described hyper-inflammatory state or immunological dysfunction, and a high prevalence of comorbidities may lead to a poorer clinical prognosis. Patients with COVID-19 have abnormal circulating blood cells associated with inflammation. Risk stratification, diagnosis, and prognosis primarily rely on hematological features, such as white blood cells and their subpopulations, red cell distribution width, mean platelet volume, and platelet count, in addition to their combined ratios. In non-small-cell lung cancer, the aggregate index of systemic inflammation (AISI), (neutrophils x monocytes x platelets/lymphocytes) is evaluated. In light of the relevance of inflammation in mortality, the objective of this study is to determine the impact of AISI on the hospital mortality of CKD patients. PATIENTS AND METHODS: This study is an observational retrospective study. Data and test outcomes of all CKD patients, stages 3-5, hospitalized for COVID-19 and followed between April and October 2021 were analyzed. RESULTS: Patients were divided into two groups according to death (Group 1-Alive, Group 2-Died). Neutrophil count, AISI and C-reactive protein (CRP) levels were increased in Group-2 [10.3±4.6 vs. 7.65±4.22; p=0.001, 2,084.1 (364.8-2,577.5) vs. 628.9 (53.1-2,275); p=0.00 and 141.9 (20.5-318) vs. 84.75 (0.92-195); p=0.00; respectively]. Receiver operating characteristic (ROC) analysis demonstrated 621.1 as a cut-off value for AISI to predict hospital mortality with 81% sensitivity and 69.1% specificity [area under ROC curve 0.820 (95% CI: 0.733-0.907), p<.005]. Cox regression analysis was used to analyze the effect of risk variables on survival. In survival analysis, AISI and CRP were identified as important survival predictors [hazard ratio (HR): 1.001, 95% CI: 1-1.001; p=0.00 and HR: 1.009, 95% CI: 1.004-1.013; p=0.00]. CONCLUSIONS: This study demonstrated the discriminative effectiveness of AISI in predicting disease mortality in COVID-19 patients with CKD. Quantification of AISI upon admission might assist in the early detection and treatment of individuals with a bad prognosis.

The effect of thrombosis-related laboratory values on mortality in COVID-19 infection.

OBJECTIVE: COVID-19 may cause thrombosis in both venous and arterial systems. Familiarity with the signs and symptoms of thrombosis and its treatment is essential in treating COVID-19 infection and its complications. D-Dimer and mean platelet volume (MPV) are measurements related to the development of thrombosis. This study investigates whether MPV and D-Dimer values could be used to determine the risk of thrombosis and mortality in the COVID-19 early stages. PATIENTS AND METHODS: 424 patients who were COVID-19 positive, according to the World Health Organization (WHO) guidelines, were randomly and retrospectively included in the study. Demographic and clinical characteristics such as age, gender, and length of hospitalization were obtained from the digital records of participants. Participants were divided into living and deceased groups. The patients' biochemical, hormonal, and hematological parameters were analyzed retrospectively. RESULTS: White blood cells (WBC), neutrophils, and monocytes were significantly different in the two groups (p-value <0.001), and their values were lower in the living group than in the deceased group. MPV median values did not differ according to prognosis (p-value = 0.994). While the median value was 9.9 in the survivors, it was 10 in the deceased. Creatinine, procalcitonin, ferritin, and the number of hospitalization days in living patients were significantly lower than in patients who died (p-value <0.001). Median values of D-dimer (mg/L) differ according to prognosis (p-value <0.001). While the median value was 0.63 in the survivors, it was found as 438 in the deceased. CONCLUSIONS: Our results did not show any significant relationship between the mortality of COVID-19 patients and their MPV levels. However, a significant association between D-Dimer and mortality in COVID-19 patients was observed.

The significance of a novel inflammatory biomarker, presepsin, in predicting disease prognosis in patients with COVID-19.

OBJECTIVE: This study aims at determining the significance of a novel inflammatory biomarker, presepsin, in predicting disease prognosis in patients with COVID-19. PATIENTS AND METHODS: This retrospective study was concluded at the University Hospital between April and August 2020. The study involved 88 COVID-19 patients (48 men and 40 women). The patients were categorized into two groups: the patients admitted to the COVID-19 clinic, described as the moderate COVID-19 patients (Group-1; n=44), and those admitted to the internal medicine outpatient clinic, who were the mild COVID-19 patients (Group-2; n=44). The groups were compared using inflammatory markers: presepsin, C-Reactive Protein to Albumin Ratio, Neutrophil to Lymphocyte Ratio, and procalcitonin. RESULTS: Serum presepsin levels (195.29 vs. 52.12 pg/ml) were significantly higher in the Group-1 compared to the Group-2 (p=0.001). The gender distribution and average age were similar in both groups (p > 0.05). While ferritin, lactate dehydrogenase, D-Dimer, platelet lymphocyte ratio, C-Reactive Protein to Albumin Ratio (p=0.001), erythrocyte sedimentation ratio, C-Reactive Protein and presepsin were significantly higher in the Group-1 compared to Group-2 (p<0.05), while hemoglobin and lymphocyte were significantly lower in the Group-1 than in Group-2 (p<0.05). CONCLUSIONS: Serum presepsin levels were found to be significantly higher in moderate clinical group COVID-19 patients compared to mild group. Presepsin, a new inflammatory biomarker, may be useful in predicting the prognosis and early treatment of COVID-19 infection.

The novel biomarker, neopterin, can predict the severity of COVID-19.

OBJECTIVE: SARS-CoV-2 infection primarily affects T-lymphocytes, particularly CD4+ and CD8+ T cells. However, there is a need for simpler and less expensive laboratory tests with predictive values comparable to CD4+ cell counts. Thus, the goal of this study was to investigate the role of neopterin levels in predicting intensive care and mortality in coronavirus disease patients in 2019. PATIENTS AND METHODS: This retrospective study included 87 hospitalized patients who were diagnosed with COVID-19. Patients were divided into two groups: those receiving intensive care (Severe COVID-19; S-COVID-19) and those receiving non-intensive care (Moderate COVID-19; M-COVID-19). Patients' clinical characteristics, serum neopterin levels, and other laboratory data were compared across groups. RESULTS: The average age was 63.9±155.2 years, and 44 (%) of the participants were male. WBC (p = 0.008), neutrophil (p = 0.002), HDL (p = 0.009), ferritin, calcium, albumin, LDH, APTT, lymphocyte, INR, D-dimer, troponin, prothrombin time sedimentation, and PaO2 (p = 0.001) were all associated with death. The neopterin level in the M-COVID-19 group was 3 (min-max; 3.1-5.9) and 3.2 (2.3-7) in the S-COVID-19 group, with no statistically significant difference (p = 0.456). Gender differences between groups were not significant (p = 0.183). According to the ROC analysis, if parameters such as age, D-Dimer, troponin, ferritin, albumin, LDH, CRP, procalcitonin, and PaO2 exceed the cut-off values and lymphocyte levels are below, it can predict the need for intensive care and mortality in COVID-19 patients. CONCLUSIONS: Although we did not find statistically significant results with neopterin in terms of mortality in COVID-19 individuals in our study, more thorough, prospective, randomized controlled studies with expanded patient populations at various phases of the disease are needed.

The role of neutrophil albumin ratio in predicting the stage of non-small cell lung cancer.

OBJECTIVE: Inflammation forms the basis of cancer development and progression. It causes changes in complete blood count parameters, such as neutrophil counts. Low albumin levels are associated with poor prognosis in cancer patients. We aimed to investigate the association between neutrophil to albumin ratio (NAR) and the stage of non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: 257 NSCLC patients (24 females and 198 males) were included in the study. Patients were divided into two groups. Group 1 (n=61) included patients with early stage cancer (stage 1 and 2), while group 2  (n=196) included those with advanced stage cancer (stage 3 and 4). Demographic data, neutrophil, lymphocyte, platelet, white blood cell counts (WBC), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), ferritin and albumin levels at the time of diagnosis were recorded. The NAR of 2 groups were compared. RESULTS: There were no significant differences between the lymphocyte count (2.0 vs. 2.0 103/mm3) and platelet count (291 vs. 311 103/mm3) of the two groups (p > 0.05). ESR (38.8 vs. 57.5 mm/h), CRP (158 vs. 57 mg/l), ferritin (85 vs. 261 ng/ml), WBC count (8.6 vs. 10.6 103/mm3), neutrophil count (5.6 vs. 7.5 103/mm3), albumin values (2.9 vs. 3.7 gr/dl), and (p < 0.05) NAR levels (1.6 vs. 2.3) (p < 0.05) were significantly higher in group 2. CONCLUSIONS: NAR can be used in predicting the stage of NSCLC.

INFLAMMATORY CELL RATIOS IN THE PATIENTS WITH FIBROMYALGIA.

Fibromyalgia is a chronic disease with undefined aetiology which commonly results in muscle sensitivity, pain, and sensitivity at certain anatomical points. The pathogenesis and aetiology of fibromyalgia are not yet fully understood. The objective of this study was to assess the diagnostic value of neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and lymphocyte/ monocyte ratio (LMR) as simple systemic inflammatory response biomarker sin patients with fibromyalgia. A total of 489 patients with fibromyalgia (group1) and 227 healthy controls (group2) were included in the study. Demographic data, Body Mass Index (BMI) neutrophil, lymphocyte and platelet counts, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels were recorded. Baseline NLR, PLR, and LMR were calculated by dividing the absolute neutrophil, platelet and lymphocyte counts by the respective divisor absolute values. The NLR, PLR, and LMR levels of the two groups were then compared. There were no significant differences in gender and age between the two groups (p>0,05). BMI levels (29.6 vs 24.8 kg/m2), mean NLR (3.63 vs. 2.11) and PLR (222.55 vs. 114.28) values were found to be statistically higher (p <0.001), and mean LMR (2.73 vs. 3.85) values were found to be statistically lower, in the patient group (p <0.001). The present study showed that NLR, PLR, AND LMR levels can be used in the diagnosis of fibromyalgia and systemic inflammation may play a role in fibromyalgia.

CLINICAL CHARACTERISTICS OF BLOOD TRANSFUSION IN GERIATRIC PATIENTS.

In the presented study, the etiology was defined in geriatric patients who received transfusions with erythrocyte suspension due to anemia; the amount of transfusion was investigated and practical systems and methods to prevent the overuse of transfusions were developed. A retrospective patient records analysis was performed for a total of 328 patients aged ≥65 who received transfusions for any reason between July 2015 and 2018 at Sakarya Research and Training Hospital. Laboratory data at initial presentation, number of erythrocyte transfusions (NES), and total volume of erythrocyte suspension transfusions (TNES) performed during all admissions over the study period were recorded. Also recorded were the demographic data, concurrent conditions, and laboratory values. Patients were divided into two groups based on their age and hemoglobin levels. Age group A1 consisted of patients between 65 and 75 years of age (inclusive), while age group A2 consisted of patients over 75 years of age (exclusive). Based on the hemoglobin levels, the patients were identified as those with a hemoglobin <8 g/dl severe anemia (group H1), hemoglobin level ranging 8-9,5 g/dl moderate anemia (H2), and hemoglobin >9,5 g/dl - mild anemia (H3). The amount of transfusion and etiological factors responsible for anemia were examined. With respect to the incidence of iron deficiency, volume of transfused erythrocyte suspensions (ES), and total number of erythrocyte suspensions (TNES) were significantly higher in the H1 group, compared to the H2 group (p:0.012 and p:0.001, respectively). Comparing H2 and H3 groups, in terms of B12 deficiency, ES, and TNES were significantly higher in the H3 group than in the H2 group (p:.0001, p:.001, p:.001, respectively). In our study, transfusion indications in patients between 65 and 75 years of age and patients aged over 75 years differed significantly in terms of cardiac conditions and hypertension. The age groups were not significantly different in terms of transfusions performed for gastrointestinal bleeding. Also, the gender distribution across these two age groups was well balanced. No significant differences were noted related either to the age or to comorbid conditions between two groups. The higher average NES and TNES values in Group A2 (> 75 years) compared to Group A1 (65-75 y) were attributed to the need for achieving cardiovascular hemodynamic stability, and to the reduced tolerance of anemia due to accompanying comorbid conditions. Despite a wide array of etiological factors in anemic geriatric patients requiring transfusions, it is of utmost importance to develop a management plan for the underlying cause of anemia in order to reduce the indications for repeated transfusions. The anemia threshold for identifying the need for transfusion should be individualized based on the physiological status of each case.

Association between attitudes towards Internet usage and health practices in high-school students in 2 schools in Turkey: a cross-sectional study.

Excessive usage of the Internet can negatively affect health and health practices especially among youth. To examine the issue among Turkish students, this study determined the association between high-school students' attitudes towards Internet usage and their health behaviour. The sample (n = 2043) was randomly drawn from all students at two high schools in Turkey: one in Anatolia and one (a vocational school) in Istanbul. Data were collected using the Structured Questionnaire, Attitude Scale towards Internet Usage (ASTIU) and Adolescent Lifestyle Profile (ALP). The mean age of the students was 16.3 years, 77.7% were male and 96.9% used the Internet; mean duration of Internet use was 18.8 h/week. Female students had more positive attitudes towards Internet usage. Mean scores for ASTIU and ALP were 72.58 (SD 17.64) and 111.34 (SD 16.61) respectively, which were average levels. There was a statistically significant but weak overall negative correlation between adolescents' attitudes towards Internet usage and their health behaviour. Our results concur with studies in different cultures which suggest some negative effects, of heavy Internet use.

ASSESSMENT OF WARFARIN TREATMENT EFFICACY BY MEANS; OF USING COAGULATION TEST RESULTS WITHIN THE THERAPEUTIC RANGE.

Time in Therapeutic Range (TTR) is a value used to assess the efficacy of Warfarin treatment. The aim of our study is to determine the effective INR levels and the rate of TTR in patients on Warfarin regimen due to Atrial Fibrillation (AF) or Mechanical Prosthetic Valve (MPV). A total of 94 patients (58 female, and 36 male, mean age: 64.9±11years) on Warfarin treatment due to AF or MPV with at least 10 INR levels measurements in the last 6 months were included in this retrospective study. The patients were divided into 2 groups. Group 1 consisted of the patients with Valvular AF (n=47); Group 2 included the patients with Non-Valvular AF (n=47); TTR and INR levels were compared. The average of INR values were found as 2,4 (min: 1,3, max: 4,3) in all patients; 2,3 (min: 1,3, max: 4,2) in Group 1; 2,6 (min: 1,3, max: 4,3) in Group 2. The average of TTR values was found 40.3% (min: 10%, max: 80%) in all patients; 43.8% (min: 10%, max: 80%) in Group 1; 36,8% (min: 10%, max: 80%) in Group 2. INR and TTR values are needed to assess the effectiveness of the Warfarin treatment. The patients in treatment with Warfarin should be well trained and frequently monitored. On the other hand, the underlying factors of the TTR values being determined as lower in the Turkish patient population might be due to the lower socio-economic and socio-cultural status, inadequate education levels, and the insufficient information on use of the medication provided by the doctors to the patients.

HEMATOLOGICAL MARKERS OF THE NO-REFLOW PHENOMEN ON IN-PATIENTS UNDERGOING PRIMARY PERCUTANEOUS CORONARY INTERVENTION.

The study aims to investigate hematological parameters of the no-reflow phenomenon (NRP) developed in patients underwent primary percutaneous coronary intervention (pPCI) due to diagnosis of ST elevation myocardial infarction (STEMI). The study sample consisted of a total of 90 patients, of which 44 patients who underwent pPCI and developed NRP without anemia and chronic renal failure (mean age was 64; 34 males and 10 females) were included in the experimental group, and the control group consisted of 46 patients with normal reperfusion flow (mean age was 58; 34 males and 12 females). In both groups, Red blood-cell Distribution Width (RDW), Mean Platelet Volume (MPV), plateletcrit (PCT), Platelet Distribution Width (PDW), and neutrophil count were observed. The demographic characteristics of both groups were similar, except the higher mean age of the experimental group (age; 64.0±12.6; 58.0±12.5). No correlation was found between development of no-reflow and incidence of risk factors such as hypertension, diabetes mellitus, dyslipidemia, smoking, family history and gender. In the no-reflow group, RDW level (16.2%±2.1; 14.2%±0.7, p<0.001), MPV level (7.9±1.2; 7.3±0.8, p<0.05), PDW level (18.1±1.2; 17.4±1.2, p<0.05), PCT level (0.2±0.06 vs 0.17±0.05) and neutrophil count (9.9±3.7; 7.1±3.3, p<0.001) was found to be higher than the control group. According to logistic regression analysis, RDW (OR; 23.4, <95% Cl 4.6-118.9, p<0.001), PDW (OR; 2.8, <95% Cl 1.2-6.4, p<0.05) and neutrophil count (OR; 1.4, Cl 1.1-1.9, p<0.05) were found to be the predictors of NRP development. Hemogram is a cheap and easy to apply test. In our study, a relationship between the NRP development and RDW, PDW, MPV, PCT, and neutrophil counts was found in patients who underwent pPCI. At the same time, RDW, PDW, and the neutrophil count were found to be predictors of no-reflow development.

EFFECTS OF VITAMIN D ANALOGS ON ERYTHROPOIESIS-STIMULATING AGENT DASAGE AND SECONDARY ANEMIA IN HEMODIALYSIS PATIENTS.

To investigate the effects of Vitamin D Analogs, paricalcitol and alphacalcidol, on hemoglobin levels and erythropoietin-stimulating agents' dosage in hemodialysis patients with chronic renal failure. A total of 310 patients under hemodialysis treatment for chronic renal failure were included in this retrospective multicenter study. Data on serum parathormone and hemoglobin levels, erythropoietin-stimulating agents' doses, C-reactive protein, calcium and phosphate levels were collected from medical records to comparatively evaluate paricalcitol, alphacalcidol and no treatment groups. Apart from significantly higher levels for hematocrit in patients treated with paricalcitol compared to pre-treatment values (32.3(3.8) vs. 34.1(3.1) p=0.007), pre-treatment and post-treatment values for biochemical parameters were similar in paricalcitol and alphacalcidol groups including ESA dose. A significant increase in parathormone levels (p=0.000 for each) while a significant decrease in calcium (p=0.003 and 0.040, respectively), Hb (p=0.001 and 0.009, respectively) and hematocrit (p=0.001 and 0.021, respectively) levels were determined in paricalcitol and alphacalcidol treated patients compared with untreated patients. Also, phosphate levels in alphacalcidol treated patients were significantly higher (p=0.018) than untreated patients. Our findings revealed insufficient suppression of parathormone levels and there of lower hemoglobin and hematocrit levels, but similar ESA dosage among CRF patients treated with Vitamin D analogs compared with untreated patients.

Retrospective evaluation of patients at follow-up with acute poisoning in Intensive Care Unit.

OBJECTIVE: Poisonings are among the major causes of emergency visits and intensive care hospitalizations. The aim of our study is to evaluate intoxicated patients at follow-up and treated in the Intensive Care Unit (ICU) in terms of demographic characteristics, type of poisonings and results of treatment. MATERIALS AND METHODS: Patients at follow-up aged 17 or older admitted with intoxication to the ICU between January 1, 2009 and December 31, 2011 were included in the study. Age, gender, presenting symptoms, duration of hospitalization, type of poisoning, the way of poisoning, medical history, seasons, hospitalization costs, treatment and prognosis of the patients were analyzed. RESULTS: Totally, 153 (8.9%) out of 1375 follow-up patients in the ICU had acute intoxication. The mean age of intoxicated patients was 29.4 ± 11, 68% of them were female, 78.4% of them were under 35 years old, and intoxication was most common in the 17-25 age group. 114 of them (94.1%) were suicidal. The most common cause of poisoning was drug-poisoning by 88.2%, and most common presenting symptoms were nausea and vomiting by 71.2%. Mean length of stay was 2.4 ± 1.6 days, and the average cost of hospitalization was 761 ± 884 Turkish Liras or 271 ± 315 USD. 5 patients (3.3%) were intubated because of respiratory failure. There was no mortal case. CONCLUSION: Suicide attempts are prominent in acute poisoning, and the young female population is at higher risk. It was found that drugs, particularly antidepressants and antipsychotic agents were the most common cause of poisoning. The high cost of treatment of acute intoxication cases is a major cause of economic burden. Clinicians should be more careful when prescribing such drugs.

Is there a difference in mad honey poisoning between geriatric and non-geriatric patient groups?

OBJECTIVE: This study aims to investigate the demographic, toxicological characteristics of the mad honey intoxication at ages 65 and above, to analyze the electrocardiographic parameters, and to compare with the mad honey intoxication at ages below 65 years. PATIENTS AND METHODS: Eighty-two patients, who had been treated and followed-up between June 2013 and November 2014 in the Emergency Service of the Findikli State Hospital, Turkey, due to diagnosis of mad honey intoxication, were included in our observational study. Age, gender, toxicological characteristics, laboratory parameters, heart rates, systolic and diastolic blood pressures, laboratory analyses and electrocardiographic data of the patients were recorded and analyzed. Patients with known coronary artery disease, chronic renal failure, arrhythmias, valvular heart disease, history of thyroid disease and electrolyte imbalance were not included in the study. RESULTS: Eighty-two (80.5% was male and the mean age was 53 ± 15 years) patients followed-up due to mad honey intoxication were included in our study. There were 64 (78%) patients aged below 65 years, and 18 (22%) patients aged 65 and above. The mean heart rate was 45 ± 7 beats/min, systolic blood pressure was 83 ± 12 mmHg and diastolic blood pressure was 52 ± 9 mmHg on admission. The onset of symptoms of the patients was found as 0.84 hours on average after mad honey consumption, the average amount of honey consumed was 3.7 ± 1.1 tablespoons, and the mean recovery time of the symptoms was found to be 1.04 hours. The most common presenting symptoms were nausea-vomiting in 82 (100%) patients and dizziness in 73 (89%) patients. Patients were found to consume mad honey mostly for achieving a remission in gastrointestinal complaints (n=18, 22%), and for utilizing its blood pressure lowering properties (n=11, 13.4%), in addition to the dietary consumption. Looking at the heart rates of the patients on admission to the emergency service, 65 (79.3%) patients had normal sinus rhythm/sinus bradycardia, 12 (14.6%) patients had a 1st degree atrioventricular block, 3 (3.7%) patients had nodal rhythm, 1 (1.2%) patient had atrial fibrillation and 1 (1.2%) patient had preexcitation. There were no significant pathological findings in the routine laboratory examinations of patients. It was found that all patients achieved normal sinus rhythm and normal blood pressure values after medical treatment, and were discharged approximately 5.65 hours after observation and follow-up. In our study, prolonged intensive-care need, pacemaker need and mortality caused by mad honey intoxication were not found. In the comparison of data of all patients above and below 65 years of age, there was a statistically significant finding that the geriatric patients consume mad honey mostly for hypotensive purposes and gastrointestinal complaints; in addition, the symptoms were starting early and the recovery period was longer in geriatric patients. CONCLUSIONS: The mad honey poisoning should be considered in previously healthy patients with unexplained symptoms of bradycardia, hypotension, and atrioventricular block. Therefore, diet history should carefully be obtained from the patients admitted with bradycardia and hypotension. And, in addition to the primary cardiac, neurological and metabolic disorders, mad honey intoxication should also be considered in the differential diagnosis. In geriatric patients admitted due to mad honey intoxication, the mad honey is usually consumed to reduce blood pressure and resolve gastrointestinal problems; and, their symptoms begin early, and last longer after mad honey consumption. In terms of other parameters, the geriatric age group has similar characteristics to non-geriatric age group.

Nutritional status and laboratory parameters among internal medicine inpatients.

BACKGROUND: Malnutrition is a clinical state resulting in prolonged hospital stay, increase in severity of infections and poor wound healing. AIMS: Our aim was to investigate the prevalence and etiologic factors of malnutrition in medical inpatients. STUDY DESIGN: A total of 290 consecutively admitted internal medicine patients from February to May 2012 were included. On admission, demographic data, anthropometric measurements, laboratory parameters and nutritional screening test results were recorded. METHODS: Nutritional risk score-2002 for patients under 65 years old, mini nutritional assessment for older patients and subjective global assessment (SGA) tests performed. Relation of demographic characteristics, laboratory parameters, weight and body mass index (BMI) with nutritional status were evaluated. RESULTS: Mean age was 61±17 years; 145 patients were male. Among 160 patients<65 years old, 34 were in malnutrition (21%), 41 (26%) were under risk of malnutrition and 85 (53%) were normal. When they were divided into three groups according to SGA, we found significant difference in hemoglobin, low density lipoprotein (LDL), high density lipoprotein, cholesterol, triglyceride, albumin and protein, weight and BMI. Among 130 patients over 65 years old, 47 patients (37%) were in malnutrition, 41 (31%) were under risk of malnutrition and 42 (32%) were normal. There was significant difference in LDL, cholesterol, albumin, protein, weight and BMI between three groups; each 1 g/dl decrease in serum albumin and age older than 65 years old increased malnutrition risk 5.21 and 1.97 times, respectively. CONCLUSION: Malnutrition risk is high among internal medicine inpatients and risk seems to be higher among older patients. Nutritional screening of geriatric patients, close follow-up and providing earlier health care would contribute rehabilitation of chronic diseases and decrease re-admissions.

Clinical and laboratory findings in mad honey poisoning: a single center experience.

OBJECTIVE: This study is aimed at analyzing the demographic and clinical characteristics, as well as the hematological-biochemical parameters of patients who admitted to the hospital with the diagnosis of mad honey poisoning. MATERIALS AND METHODS: A total of 16 patients who were admitted with mad honey intoxication symptoms and treated in Emergency Department of Sakarya Education and Research Hospital between January 2009 and December 2012 were included in the study. Demographic and clinical characteristics of the patients and hematological, biochemical parameters were obtained from hospital records. Heart rate, systolic and diastolic blood pressure on admission and at discharge were obtained retrospectively. RESULTS: Sixteen patients (10 males and 6 females, mean age 58.5 ± 10 years, range between 41 and 79) were included in our study. Heart rate was 42 ± 6 beats/min, systolic blood pressure was 73 ± 19 mmHg, and diastolic blood pressure was 45 ± 17 mmHg on admission. In the evaluation of the patients' heart rhythms on admission to the emergency room, nine (56.3%) patients had sinus bradycardia, three (18.8%) patients had nodal rhythm, two (12.5%) patients had first degree atrioventricular block, and two (12.5%) patients had atrial fibrillation. Atropine 1.1 ± 0.4 mg and saline 1125 ± 465 ml were used to treat patients. Patients were discharged with a stable condition after an average 27.7 ± 7.2 h of follow-up. Heart rate was 75 ± 8 beats/min, systolic blood pressure was 132 ± 7 mmHg, and diastolic blood pressure was 82 ± 6 mmHg at discharge. Mortality was not observed. Hematological and biochemical parameters measured at the time of admission were within normal ranges. CONCLUSION: Mad honey poisoning should be considered in previously healthy patients with unexplained symptoms of bradycardia, hypotension, and cardiac dysrhythmias. Therefore, diet history should carefully be obtained from the patients admitted with bradycardia and hypotension, and mad honey intoxication should also be considered in the differential diagnosis, as well as primary cardiac, neurologic, and metabolic disorders. Mad honey poisoning may be presented with life-threatening symptoms without any hematological and biochemical disorder.

Emergent endovascular repair of ruptured abdominal and thoracic aortic aneurysms in a single center: midterm outcomes.

OBJECTIVE: Endovascular therapies may offer distinct advantages in acute aortic syndromes. In this paper, we present our experience with emergent endovascular repair of both abdominal and thoracic aortic ruptures and report early and midterm out comes. METHODS: Data from all patients (n=96) who were treated by endovascular procedures between 2004 to 2012 were prospectively collected and early-midterm outcomes of the emergency (e) interventions for both abdominal (EVAR) and thoracic (TEVAR) aortic ruptures (n=20) were retrospectively analysed. RESULTS: The mean age was 65 +- 11 years (range: 27-77 years)and 18 patients (90%) were male. Mean follow-up duration was 28 ± 21.2 months (range=1-57). Thirteen patients were treated by eEVAR (65%) and 7 by eTEVAR (35%). One patient who had a rupture of the aneurysm at arcus aorta level was treated by hybrid procedure (eTEVAR+ debranching).The hospital mortality rate was 20% (n=4) for all cases, 23.0% (n=3) for eEVAR and 14.2% (n=1) for eTEVAR. In the follow-up period, 3 patients (15.0%) had reinterventions. DISCUSSION: Reinterventions and the necessity of close follow-up are the disadvantages of endovascular procedures.Even if that is the case, we believe that eEVAR eTEVAR in the acute setting of ruptured aorta in patients with suitable anatomy is a lifesaving option.

Slow ventricular response atrial fibrillation related to mad honey poisoning.

Mad honey poisoning which is induced by Grayanotoxin (Andromedotoxin), is also known to have adverse effects in the cardiovascular system leading to different clinical entities. This toxin is produced by a member of the Rhododendron genus of plants of two R. Luteum and R. Panticum. In this article, we presented a case of slow ventricular response atrial fibrillation complaints with nausea, vomiting, dizziness and chest pain about an hour after eating honey produced in the Black Sea Region.
