Evaluation of plasma cholecystokinin levels and gallbladder functions in hyperemesis gravidarum: a prospective cohort study.

This is a prospective cohort study aimed to compare women treated due to hyperemesis gravidarum (HG) (n = 24) to women with normal pregnancy attending regular antenatal outpatient care (n = 22) in terms of fasting and post-prandial cholecystokinin (CCK) levels, and gallbladder (GB) functions. The Pregnancy-Unique Quantification of Emesis (PUQE) scores, fasting and postprandial CCK levels, and ultrasonographic GB parameters were recorded at admission before any treatment. The median PUQE score in the study group was 8. There were no statistically significant differences in GB parameters (p>.05), and fasting and postprandial CCK levels between the groups (p=.851, p=.395, respectively). Fasting CCK levels were positively correlated with postprandial GB volume (PGv) (p=.022, r = 0.464). Although GB contractility is compromised during pregnancy, HG does not cause further GB impairment. The positive correlation between fasting CCK levels and PGv requires further evaluation. Impact StatementWhat is already known on this subject? The pathophysiology of hyperemesis gravidarum (HG) remains poorly understood. Altered cholecystokinin (CCK) levels may have potential consequences on gastric emptying, which may be related to nausea and vomiting. In this context, alterations in CCK secretion in women diagnosed with HG have been previously reported, and alterations in CCK levels lead to impaired gallbladder (GB) functions.What do the results of this study add? CCK levels and GB functions in pregnant women with HG are not statistically significantly different from those in healthy pregnant women.What are the implications of these findings for clinical practice and/or further research? Further studies designed in patients with different severities of HG and larger sample sizes are required for a better understanding of HG pathophysiology.

A New Risk-Scoring System for Colorectal Cancer and Polyp Screening by Turkish Colorectal Cancer and Polyp Study Group.

BACKGROUND: Colorectal cancer is one of the most commonly diagnosed types of cancer worldwide. An early diagnosis and detection of colon cancer and polyp can reduce mortality and morbidity from colorectal cancer. Even though there are a variety of options in screen- ing tests, the question remains on which test is the most effective for the early detection of colorectal cancer. In this prospective study, we aimed to develop a simple, useful, effective, and reliable scoring system to detect colon polyp and colorectal cancer. METHODS: We enrolled 6508 subjects over the age of 18 from 16 centers, with colonoscopy screening. The age, smoking status, alcohol consumption, body mass index, polyp incidence, polyp size, number and localization, and pathologic findings were recorded. RESULTS: The age, male gender, obesity, smoking, and family history were found as independent risk factors for adenomatous polyp. We have developed a new scoring system which can be used for these factors. With a score of 4 or above, we found the following: sensitivity 81%, specificity 40%, positive predictive value 25.68%, and negative predictive value 89.84%, for adenomatous polyp detection; and sensitivity 96%, specificity 39%, positive predictive value 3.35%, negative predictive value 99.29%, for colorectal cancer detection. CONCLUSION: Even though the first colorectal cancer screening worldwide is generally performed for individuals over 50 years of age, we recommend that screening for colorectal cancer might begin for those under 50 years of age as well. Individuals with a score ≥ 4 must be included in the screening tests for colorectal cancer.

COVID-19 Pneumonia After SARS-CoV-2 Vaccination with CoronaVac: A Case Series from Turkey.

Coronavirus disease 2019 is a novel viral infection that has caused a pandemic globally. Many kinds of vaccine development studies were conducted to prevent the spread and deaths. The CoronaVac is the most commonly used vaccine in Turkey. Phase 3 trials from various countries revealed that CoronaVac efficacy ranged from 50.7% to 91.25% but increased in moderate or severe cases to 100%. Additionally, it was remarkable owing to high seroconversion rates achieving up to 100%. After the vaccine campaign began in Turkey, critically ill patients continued to admit to our center's intensive care unit though they had been vaccinated with 2 doses of CoronaVac. The clinical course of these patients revealed that they are still at high risk of severe disease and death. Therefore, we aimed to share these patients' clinical characteristics and disease course, laboratory, and radiologic data.

Some biological properties of spiny eel (Mastacembelus mastacembelus, Banks & Solander, 1794) living in the Upper Euphrates River Basin, Turkey.

This study was carried out to determine some bioecological characteristics of Mastacembelus mastacembelus, which is the only species of Mastacembelidae family living in Turkey. Fish samples were caught between 2014-2018 from Keban Dam Lake, one of the most important reservoirs of the upper Euphrates Basin. In totally, 348 Mastacembelus mastacembelus individuals were examined, including 178 males and 170 females. The age distributions were defined between the I-XV age groups. Total lengths ranged from 14.20 to 81.80 cm in males and from 15.60 to 77.30 cm in females. Total length-weight relationships were calculated as W = 0.0083 × TL2.6516 for males, W = 0.0043 × TL2.8310 for females and W = 0.0063 × TL2.7256 for all population, and the growth type was estimated as "negative allometric". The von Bertalanffy growth parameters for all individuals were computed as L∞ = 90.99, k = 0.13, t0 = - 0.45. The total (Z), natural (M), fishing (F) mortality rates and exploitation rate (E) were estimated as Z = 0.313, M = 0.270, F = 0.043 and E = 0.137, respectively. The length at first capture (Lc) was found as 50.72. The optimum, maximum and economic yields were calculated as E0.5 = 0.361; Emax = 0.776; E0.1 = 0.664, respectively.

Analysis of factors among 30-day and 1-year mortality rates in patients with borderline stable-unstable intertrochanteric hip fracture.

OBJECTIVE: This study aimed to evaluate the possible effects of surgical procedures on mortality and to identify the possible risk factors for mortality in the management of geriatric hip fractures. METHODS: A total of 191 patients (105 women and 86 men; mean age 82.26±9.681 [60-108] years) with AO/OTA 31A2.2 intertrochanteric fractures and treated with sliding hip screw, proximal femoral nail, or hemiarthroplasty were included in this retrospective cohort study. The treatment type was decided by the responsible surgeon according to the patients' pre-injury activity level, bone quality, and features of the fracture. Age, sex, type of fracture, type of surgery performed, American society of anesthesiology (ASA) grade, type of anesthesia, time to surgery, type of physical therapy, length of hospital stay, and number of comorbidities were documented. We evaluated the 30-day and 1-year mortality of patients treated with sliding hip screw (SHS), proximal femoral nail antirotation (PFN-A), or hemiarthroplasty and identified the possible risk factors for mortality. RESULTS: A total of 49 patients underwent SHS, 58 underwent PFN-A, and 84 underwent hemiarthroplasty. Of these, 2 patients with SHS, 2 with PFN-A, and 11 with hemiarthroplasty died within 30 days after surgery, whereas 7 patients with SHS, 15 with PFN-A, and 23 with hemiarthroplasty died 1 year after surgery. The 30-day and 1-year overall mortality rates were 7.9% and 23.6%, respectively. Both the 30-day and 1-year mortality risks were higher in patients undergoing hemiarthroplasty than in patients undergoing SHS (p=0.068 versus 0.058). The 30-day mortality was higher in patients receiving general anesthesia than in those receiving combined spinal and epidural anesthesia (p=0.009). The 1-year mortality risk was higher in patients with ASA grade 4 than in those with grade 1 and 2 (p=0.045). Advanced age (p=0.022) and male sex (p=0.007) were also found to be the risk factors for 1-year mortality. CONCLUSION: We demonstrated that higher ASA grade, male sex, general anesthesia, and hemiarthroplasty procedures are associated with higher mortality rates in elderly patients with hip fractures. Thus, we highly recommend orthopedic surgeons to consider all these factors in the management of intertrochanteric hip fractures in the geriatric population. LEVEL OF EVIDENCE: Level IV, Prognostic Study.

Potency and use of chia mucilage coating containing propolis liquid extract for improves shelf-life of sea bass fillets.

BACKGROUND: In this study the effects of the use of chia mucilage - CM coating in combination with propolis liquid extract - PLE on the physico-chemical (total volatile basic nitrogen - TVB-N, peroxide value - PV, thiobarbituric acid - TBA) and bacteriological (total viable count - TVC, psychrophilic bacteria count -PBC) quality properties of sea bass fillets during storage at 2°C, as well as its potency, were investigated. METHODS: The fillets were randomly separated into four lots and subjected to the following treatments by dipping: chia mucilage - CM, chia mucilage + 0.1% PLE, chia mucilage + 0.3% PLE and control (uncoated), then stored at 2°C. RESULTS: The results showed that the chia musilage coating containing PLE was effective on TVC and PCA. While the shelf life of the control group was 8 days, the CM + 0.3% PLE group was 20 days. CONCLUSIONS: According to these results, it can be said that chia mucilage coating preserves the shelf life and quality of chilled seafood and can be used safely as a coating material.

Real-world efficacy and safety of Ledipasvir + Sofosbuvir and Ombitasvir/Paritaprevir/Ritonavir ± Dasabuvir combination therapies for chronic hepatitis C: A Turkish experience.

BACKGROUND/AIMS: This study aimed to evaluate the real-life efficacy and tolerability of direct-acting antiviral treatments for patients with chronic hepatitis C (CHC) with/without cirrhosis in the Turkish population. MATERIAL AND METHODS: A total of 4,352 patients with CHC from 36 different institutions in Turkey were enrolled. They received ledipasvir (LDV) and sofosbuvir (SOF)±ribavirin (RBV) orombitasvir/paritaprevir/ritonavir±dasabuvir (PrOD)±RBV for 12 or 24 weeks. Sustained virologic response (SVR) rates, factors affecting SVR, safety profile, and hepatocellular cancer (HCC) occurrence were analyzed. RESULTS: SVR12 was achieved in 92.8% of the patients (4,040/4,352) according to intention-to-treat and in 98.3% of the patients (4,040/4,108) according to per-protocol analysis. The SVR12 rates were similar between the treatment regimens (97.2%-100%) and genotypes (95.6%-100%). Patients achieving SVR showed a significant decrease in the mean serum alanine transaminase (ALT) levels (50.90±54.60 U/L to 17.00±14.50 U/L) and model for end-stage liver disease (MELD) scores (7.51±4.54 to 7.32±3.40) (p<0.05). Of the patients, 2 were diagnosed with HCC during the treatment and 14 were diagnosed with HCC 37.0±16.0 weeks post-treatment. Higher initial MELD score (odds ratio [OR]: 1.92, 95% confidence interval [CI]: 1.22-2.38; p=0.023]), higher hepatitis C virus (HCV) RNA levels (OR: 1.44, 95% CI: 1.31-2.28; p=0.038), and higher serum ALT levels (OR: 1.38, 95% CI: 1.21-1.83; p=0.042) were associated with poor SVR12. The most common adverse events were fatigue (12.6%), pruritis (7.3%), increased serum ALT (4.7%) and bilirubin (3.8%) levels, and anemia (3.1%). CONCLUSION: LDV/SOF or PrOD±RBV were effective and tolerable treatments for patients with CHC and with or without advanced liver disease before and after liver transplantation. Although HCV eradication improves the liver function, there is a risk of developing HCC.

Knee Pain and Functional Scores After Intramedullary Nailing of Tibial Shaft Fractures Using a Suprapatellar Approach.

OBJECTIVES: To evaluate the effects of intramedullar nailing of the tibia using a suprapatellar (SP) approach with respect to pain and function of the knee. DESIGN: Prospective clinical investigation. SETTING: Academic level I trauma center. PATIENTS/PARTICIPANTS: Twenty-one patients with tibial shaft fractures (Orthopaedic Trauma Association 42A-B-C) with a minimum of 12-month follow-up. INTERVENTION: Locked intramedullary nailing using a SP approach. MAIN OUTCOME MEASUREMENTS: Radiographic evaluation for nail position proximally, tibial shaft alignment and union, anterior knee pain using the visual analog scale, and knee function evaluation using the Lysholm and SF-36 scores. Examination of intra-articular damage was performed using intraoperative patellofemoral arthroscopy before and after nail insertion. RESULTS: The mean age of the patients was 35.4 ± 12.4 years (range, 18-63 years), and the mean follow-up period was 15.62 ± 3.2 months (range, 12-21 months). The visual analog scale score for anterior knee pain was a mean of 1.0 ± 1.3 (range, 0-4). The SF-36 physical score was mean 45.1 ± 9, and the SF-36 mental score was a mean of 51.7 ± 9.9. The knee joint range of movement was measured as 133.1 ± 87 degrees on the affected extremity side and 134.05 ± 8.4 degrees on the unaffected side. The mean Lysholm knee score was 95.76 ± 4. No intra-articular pathology was seen on arthroscopy after nail insertion. CONCLUSIONS: The SP approach for intramedullar nailing for tibial shaft fractures was not associated with either anterior knee pain or functional limitations of the knee in our series. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Efficiency of instant messaging applications in coordination of emergency calls for combat injuries: A pilot study.

BACKGROUND: Coordination of an emergency response team is an important determinant of prompt treatment for combat injuries in hospitals. The authors hypothesized that instant messaging applications for smartphones could be appropriate tools for notifying emergency response team members. The objective of this study was to investigate the efficiency of a commercial instant messaging application (WhatsApp, Mountain View, CA) as a communication tool for the emergency team in a level-I trauma center. METHODS: We retrospectively evaluated the messages in the instant messaging application group that was formed to coordinate responses to patients who suffered from combat injuries and who were transported to our hospital via helicopter during an 8-week period. We evaluated the response times, response time periods during or outside of work hours, and the differences in the response times of doctors, nurses, and technicians among the members of the emergency team to the team leader's initial message about the patients. RESULTS: A total of 510 emergency call messages pertaining to 17 combat injury emergency cases were logged. The median time of emergency response was 4.1 minutes, 6 minutes, and 5.3 minutes for doctors, nurses, and the other team members, respectively. The differences in these response times between the groups were statistically significant (p=0.03), with subgroup analyses revealing significant differences between doctors and nurses (p=0.038). However, no statistically significant differences were observed between the doctors and the technicians (p=0.19) or the nurses and the technicians (p=1.0). From the team leader's perspective, using this application reduced the workload and the time loss, and also encouraged the team. CONCLUSION: Instant messaging applications for smartphones can be efficient, easy-to-operate, and time-saving communication tools in the transfer of medical information and the coordination of emergency response team members in hospitals.

The relationship between heterotopic gastric mucosa in the cervical esophagus and laryngopharyngeal reflux.

OBJECTIVES: This study aims to investigate the possible correlations between the heterotopic gastric mucosa (HGM) islets in the cervical esophagus and laryngopharyngeal reflux (LPR). PATIENTS AND METHODS: Between May 2010 and April 2011, 45 patients (36 females, 9 males; mean age 39.8±14.1 years; range 18 to 72 years) who had reflux symptom index (RSI) >10 and reflux finding score (RFS) >7 were included. The study group consisted of 21 patients who were diagnosed with HGM islets in the cervical esophagus, while control group consisted of 24 patients without any HGM islets assessed by upper gastrointestinal system endoscopy. Esophagus manometric examination and dual-channel 24-hour pH monitoring were performed on all patients. RESULTS: Pretreatment mean RSI and RFS were 25.6±3.5 and 15.1±3.4 in group 1, while it was found to be 21.1±4.4 and 11.9±2.6 in group 2 (p=0.001, p=0.001). A total of 29.7% of patients who underwent pH monitoring had distal reflux, whereas 43.2% of them had proximal reflux. In group 1, distal reflux was observed in 15.4% and proximal reflux was found in 54% of the patients, while distal reflux was observed in 38% and proximal reflux was found in 38% of the patients in group 2 (p=0.152; p=0.27). Fourteen patients diagnosed with HGM had antral- and seven patients had fundal-type epithelium. CONCLUSION: Our study results suggest that HGM islets may be considered as an etiological factor in the patients with severe LPR with isolated proximal reflux based on the 24-hour pH monitoring.

The advantage of retrieval PEG tubes in patients with buried bumper syndrome - a case report.

The aging population has resulted in an increasing need for long-term enteral nutrition of patients with a wide range of disabling conditions. Percutaneous endoscopic gastrostomy is one of the applicable methods for long-term enteral nutrition support. The buried bumper syndrome is a rarely encountered but grave complication of percutaneous endoscopic gastrostomy. Various internal and external methods have been described for the removal of the buried bumper. Removing the percutaneous endoscopic gastrostomy tube by external traction without an abdominal incision can resolve this problem efficiently, especially in cases in whom retrieval-type percutaneous endoscopic gastrostomy tubes have been used. We report a case of buried bumper syndrome as a late complication of percutaneous endoscopic gastrostomy placement. We removed the buried bumper with external traction and placed a new percutaneous endoscopic gastrostomy tube in a different site because of the peristomal infection.
