Abstract
Background Ambulatory anorectal surgeries have increased in the last few years. This clinical study aimed to compare general operating room conditions with outpatient procedures for simple anal fistulas in terms of healing success, recurrence, cost, complications, and sustainability. Methodology Only primary fistulotomy and seton application for simple anal fistulas were retrospectively analyzed. Results Two-hundred fifty patients (73.7%) were male, and 89 (26.3%) were female. Sixty patients (17.7%) were treated in the operating room, and 279 (82.3%) were treated in the outpatient clinic conditions. Of the ambulatory surgeries, 160 patients underwent fistulotomy and 119 patients loose seton. On the other hand, 34 patients underwent fistulotomy and 26 patients loose seton in operating room conditions. No significant difference was found between the groups according to the distribution of age, gender, complications, and recurrence (P > 0.05). Cost-effectiveness assessment according to the place (ambulatory/operating room) and type of operation (fistulotomy/loose seton) reveals that ambulatory surgery provides significantly more savings (P < 0.001). Conclusions For simple anal fistulas, ambulatory anorectal surgery is a safe approach that can be performed at a lower cost than operating room conditions.

Abstract
Transcriptional and translational control are key determinants of gene expression, however, to what extent these two processes can be collectively coordinated is still poorly understood. Here, we use Nanopore long-read sequencing and cap analysis of gene expression (CAGE-seq) to document the landscape of 5' and 3' untranslated region (UTR) isoforms and transcription start sites of epidermal stem cells, wild-type keratinocytes and squamous cell carcinomas. Focusing on squamous cell carcinomas, we show that a small cohort of genes with alternative 5'UTR isoforms exhibit overall increased translational efficiencies and are enriched in ribosomal proteins and splicing factors. By combining polysome fractionations and CAGE-seq, we further characterize two of these UTR isoform genes with identical coding sequences and demonstrate that the underlying transcription start site heterogeneity frequently results in 5' terminal oligopyrimidine (TOP) and pyrimidine-rich translational element (PRTE) motif switches to drive mTORC1-dependent translation of the mRNA. Genome-wide, we show that highly translated squamous cell carcinoma transcripts switch towards increased use of 5'TOP and PRTE motifs, have generally shorter 5'UTRs and expose decreased RNA secondary structures. Notably, we found that the two 5'TOP motif-containing, but not the TOP-less, RPL21 transcript isoforms strongly correlated with overall survival in human head and neck squamous cell carcinoma patients. Our findings warrant isoform-specific analyses in human cancer datasets and suggest that switching between 5'UTR isoforms is an elegant and simple way to alter protein synthesis rates, set their sensitivity to the mTORC1-dependent nutrient-sensing pathway and direct the translational potential of an mRNA by the precise 5'UTR sequence.

Abstract
Abstract
Objective: Although due to the Covid-19 Pandemic, elective surgeries have been postponed worldwide, emergency operations cannot be delayed and are being performed. In general surgery practice, incarcerated / strangulated inguinal hernias have a prominent place among emergency surgeries. In 1% of these patients, the hernia content reduces spontaneously into the abdomen until the hernia sac is opened. It is imperative that these bowel segments be evaluated for possible intestinal necrosis.
Methods: Patients who underwent emergency surgery and hernioscopy in the Sakarya Training and Research Hospital General Surgery Service due to incarcerated or strangled inguinal hernia during the period from March 2020 to October 2020 were included in the study. Hernioscopy procedure was performed using single-port and glove-port methods. For each patient, age, duration of complaints, comorbidities, hernia repair method, operation time, incarcerated organ, whether ischemia improved after reduction or whether resection was required, postoperative complications were recorded.
Results: Hernioscopy was performed on ten patients due to strangled inguinal hernia during the eight months. While femoral hernia was detected in 2 patients, eight patients had an inguinal hernia. In 1 patient, bowel resection and anastomosis were performed with the transabdominal approach because the small intestine necrosis was detected during the hernioscopy procedure.
Conclusion: The hernioscopy method, which is performed under spinal anesthesia, prevents unnecessary laparotomies and should be preferred more during the COVID-19 pandemic process in patients who are urgently operated for strangled inguinal hernia.

Abstract
<b> Objective: </b> Cecal diverticulitis may be encountered as a real etiological factor in 1/300 appendectomies. Differential diagnosis of acute appendicitis and cecal diverticulitis is crucial because of the different treatment methods. Our aim is to reveal the importance of distinguishing acute appendicitis from cecal diverticulitis. <p> <b>Methods: </b> The data of patients who were admitted to the hospital between 2015 and 2019 with the complaint of abdominal pain and then finally diagnosed with colon diverticular disease, colon diverticulitis, or acute appendicitis, analyzed retrospectively. <p><b>Results: </b> A total of 19 cecum diverticulitis patients were detected during surgery for acute appendicitis or during clinical and radiological evaluation. 1247 appendectomies were evaluated; the final diagnosis was observed as cecal diverticulitis in 5 patients (0,4%). One hundred nineteen patients diagnosed with colonic diverticulitis at admission were evaluated, while 105 (88,2%) of them had left-sided diverticulitis, 14 (11,7%) of them had solitary cecal diverticulitis. All of the solitary cecal diverticulitis patients were treated conservatively, except one patient who has Hinchey 3 diverticulitis.<p><b> Conclusion: </b> Differential diagnosis of cecum diverticulitis with acute appendicitis is important because cecum diverticulitis can be managed as conservatively in most cases. In order to prevent unnecessary surgical interventions, this importance has increased, especially during the COVID-19 pandemic period.

Abstract
BACKGROUND Acute appendicitis is the most common non-gynecological emergency during pregnancy. The diagnosis of appendicitis during pregnancy is challenging due to changes in both physiological and laboratory variables. Guidelines suggest patients with suspected acute appendicitis should be stratified based on clinical scoring systems, to optimize the use of diagnostic imaging and prevent unnecessary surgery. Surgeons require additional information beyond that provided by imaging studies before deciding upon exploratory laparoscopy in patients with a high suspicion of appendicitis. Various scoring methods have been evaluated for the diagnosis of acute appendicitis. However, there is no consensus on a method to use during pregnancy, and a detailed comparison of existing scoring methods for this purpose has not yet been conducted. The purpose of this study was to evaluate the efficacy of the most popular scoring systems applied to diagnose acute appendicitis during pregnancy. METHODS This single-center retrospective study included 79 pregnant patients who were admitted to the emergency department with abdominal pain between May 2014 and May 2019. The patients were diagnosed with acute appendicitis and underwent an appendectomy. As a control group, the study also included 79 non-pregnant patients who underwent appendectomy within the last 1.5 years. To ensure that the groups were similar, women in the case group were stratified according to age, and the proportions of women in the strata were determined. The women in the control group were similarly stratified. Women were randomly selected from the strata to prevent bias. Both laboratory and examination findings required for each scoring method were obtained and assessed separately for each patient. Negative appendectomy rates were evaluated according to pathology results. Categorical variables were compared using the chi-square test. A p value < 0.05 was considered to indicate significance. Receiver operator characteristic curve analysis was used to identify the best threshold value and to assess the performance of the test scores in terms of diagnosing appendicitis. RESULTS Among all scoring systems, the Tzanakis score was most efficacious at predicting appendicitis in non-pregnant women. The positive predictive value (PPV) of the Tzanakis score was 90.6%, whereas the negative predictive value (NPV) was 46.7%. The RIPASA score performed the best among the scoring systems in pregnant women. It was associated with a PPV of 94.40%, NPV of 44%, and sensitivity and specificity of 78.46% and 78.57%, respectively. CONCLUSION Although the RIPASA score can be used to efficaciously diagnose acute appendicitis in pregnant women, a specific scoring system is needed for diagnosis during the gestation period.

Abstract
Abstract
Due to higher mechanical demands on technical parts, the application of short fiber reinforced thermoplastics for injection molding is strongly increasing. Therefore, more attention needs to be paid to the optimization of their recycling processes. Mechanical shredding of thermoplastics into granules is a common recycling method within polymer industries. The breaking of polymer chains and reinforcing fibers during this process may affect the material properties. This study presents the effect of ten recycling sequences on four different materials: polypropylene, glass fiber filled polypropylene, carbon fiber filled polypropylene and flax fiber filled polypropylene. Tests indicate that recycling has a negative influence on most of the mechanical properties. Polypropylene without fibers forms an exception as it does not exhibit any significant change in material properties. Glass fiber and carbon fiber reinforced polypropylene show a decrease in stiffness and tensile strength during the recycling steps. The impact strength of carbon and flax fiber reinforced polypropylene increases whereas that of glass fiber reinforced polypropylene decreases.

Abstract
Posterior reversible encephalopathy syndrome (PRES) is an entity characterized by headache, altered mental status, seizures, visual disturbances, and focal neurological signs. The most common etiologies of PRES are hypertension and renal failure, and the most frequent pathophysiology is hyperperfusion. PRES is generally symmetrical, often in the occipital and parietal lobes, and is typically characterized by vasogenic edema in the subcortical white matter. This study involves a 38-year-old female patient who had hypertension, used immunosuppressive drugs and was also found to have nephropathy. After 3 months of treatment for PRES, the patient's symptoms had declined.

Abstract
Hereditary angioedema is an autosomal-dominant disorder caused by mutation of the gene encoding the C1 esterase inhibitor (C1-INH). It manifests as painless, nonpruritic, nonpitting episodic swelling of the subcutaneous tissues, gastrointestinal, and upper respiratory tracts in the absence of urticaria. An attack typically takes 24 h to peak and resolves over 48-72 h. The most serious manifestation is a laryngeal attack associated with upper airway swelling. The aim of this case report is to describe the lifesaving use of a novel C1-INH protein concentrate in a patient with mild-to-moderate dyspnea caused by swelling of the upper airway (larynx) and tongue.

Abstract
Differential diagnosis of the acute flank pain in a patient without nephrolithiasis is challenging in emergency department. Renal infarction should be suspected if accompanying cardiac arrhythmia, heart failure or valvular disease is present. Activated protein C resistance is the most common thrombophilia that triggers venous-obstructive conditions and rarely arterial thromboembolism. We described a young male with a history of non-ischemic dilated cardiomyopathy and coexisting activated protein C resistance presented with new onset acute flank pain due to acute renal infarction.

Abstract
INTRODUCTION The aim of this study is to determine the efficiency of levofloxacin containing sequential therapy with or without bismuth in Helicobacter pylori (Hp) eradication in nonulcer dyspepsia. MATERIALS AND METHODS One hundred and ninety Hp-positive patients with the pre-diagnosis of nonulcer dyspepsia were included in this study. Patients were randomized into 2 groups and 95 individuals were included in each group. The first group was administered levofloxacin containing sequential therapy with bismuth, whereas the second group was administered only levofloxacin containing sequential therapy. Rates of therapy discontinuation and eradication success were compared between the 2 groups. Furthermore, symptomatic healing rates were com-pared between patients in whom Hp eradication was achieved and in whom it was not achieved. RESULTS Ninety-one patients from each group applied for follow-up after treatment. It was found that 7/91(7.6%) patients from the first group and 5/91(5.4%) patients from the second group did not complete the therapy (p >0.05). In patients who completed therapy, Hp eradication was achieved in 72 out of the 84 patients (85.2%) from the first group and 71 out of 86 patients (82.6%) from the second group (p > 0.05). In addition, symptomatic healing occurred in 125 out of 143 patients (87.4%) in whom Hp was eradicated and 12 out of 27 (44.4%) patients in whom Hp was not eradicated (p < 0.001). CONCLUSION Levofloxacin containing sequential therapy for 14 days is quite effective and well-tolerated choice for Hp eradication. However, adding bismuth to sequential therapy does not significantly improve Hp eradication success rates. Therefore, Hp eradication is beneficial and necessary in patients with nonulcer dyspepsia.
