Platelet vesiculation is common factor contributing in coagulation and thromboembolism in patients with atrial fibrillation (AF). Platelet-derived vesicles are involved in the coagulation, thromboembolism, microvascular inflammation, arterial stiffness, vascular calcification, atherosclerotic plaque shaping and rupture, endothelial dysfunction, cardiac remodelling, and kidney dysfunction. Recent clinical studies have revealed elevated concentrations of platelet-derived vesicles in peripheral blood of patients with current AF and history of AF. The aim of the mini review is to discuss the role of platelet-derived micro vesicles as predictive biomarker in AF. Serial measures of circulating levels of platelet-derived vesicules are discussed to be useful in stratification of AF patients at risk of thromboembolic complications, but there is limiting evidence regarding their predictive value that requires further investigations in large clinical trials.

Background: The COVID-19 pandemic has resulted in significant burdens globally. Healthcare workers (HCWs), at the heart of the unparalleled crisis of COVID-19, face challenges treating patients and doing testing for COVID-19: reducing the spread of infection; developing suitable short-term strategies; and formulating long-term plans. We aimed to assess the psychological impact of COVID-19 on Laboratory health staff. Material and methods: Between February - March 2021, 72 laboratory staff workers of a tertiary care teaching hospital were invited to fill out a questionnaire regarding concerns and worries about the novel coronavirus pandemic, along with a coping scoring system and General health questionnaire level (GHQ-12) survey. Results: Out of 72 laboratory health staff who completed the survey questionnaire, 10 were faculty members, 17 were residents (including senior residents, junior residents, and demonstrators), 39 were lab technicians, followed by 4 were attendants and 2 were data operators. Laboratory staff workers with an age group range from 30 years - 60 years had a higher level of depression symptoms than respondents with 20 years - 29 years of age. Similarly, the symptoms of anxiety were noted to be significantly higher among female respondents and respondents with age >30yrs. The most frequent concern was transmitting the infection to family than to themselves only. A considerable number of laboratory staff workers utilized online psychological resources to deal with their psychological distress.Conclusion: The findings of this survey recognize the various problems faced by laboratory health workers during the period of COVID-19 which affect their working ability. Therefore, in the future, we have to implement such strategies that enhance the performance of laboratory workers, boost their energy level, and encourage them to take care of themselves, in times of such crisis.

Objective: The present study aimed to evaluate the accuracy of the Omron HBP-9031C automated oscillometric upper-arm blood pressure (BP) measurement device for blood pressure monitoring, according to the ANSI/AAMI/ISO 81060-2:2013 protocol (ANSI/AAMI/ISO). Participants and Method: The device evaluations were performed in 85 participants, who fulfilled the inclusion criteria of the protocol. The validation procedure and data analysis followed the protocol precisely. Results: In the ANSI/AAMI/ISO 81060-2-2013 validation procedure (criterion 1), the mean ± SD of the differences between the test device and reference BP was 0.5 ± 7.84/-1.9 ± 6.30 mmHg (systolic/diastolic). The mean differences between the two observers and the Omron HBP-9031C were 0.5 ± 6.69 mmHg (range, −18 to 15 mmHg) for systolic BP and -1.9 ± 5.63 mmHg (range, −17 to 14 mmHg) for diastolic BP, according to criterion 2. The two criteria of the ANSI/AAMI/ISO were fulfilled. Conclusion: The professional OMRON BP monitor, HBP-9031C fulfilled the requirements of the ANSI/AAMI/ISO validation standard and can be recommended for clinical use.

Successful implant restoration is depending on an adequate surgical and prosthetic protocol. In the last few years an increase in Peri-Implantitis has been attributed, in part, to the excess cement left around the implant collar and threads, leading in many cases to bone loss and even the complete failure of the implant treatment [1-5]. This article will attempt: 1. To describe a proper cementation protocol for cement-retained implant restorations to reduce cement induced implant failures, and 2. To review the alternative implant restorative options to cement-retained crowns such as screw-retained restorations, screwless and cementless implant restorations, screw-retained-cemented implant crown, angulated screw channel restorations, the lingual locking screw-retained restorations and the multi-unit abutment restorations.

Introduction: Hypertension is a silent pathology in a way that affects all four spheres to be considered as such; magnitude, transcendence vulnerability, and feasibility. The World Health Organization estimates that 45% of deaths from heart disease and 51% of deaths from stroke globally are caused by hypertension. Material and method: A longitudinal, descriptive and quantitative observational study was carried out on the personnel of high-risk public service providers. Results: The total population sampled was 550 people where it was possible to determine the sex where the disease predominates, since 92% of the hypertensive population belong to the male sex, while 8% of the female population. 57% of the total population were classified as normotensive, while 21% were classified as High Normal, Grade I Hypertension, and Grade II Hypertension. Discussion: AHT is the result of a series of interactions between endogenous and exogenous factors in an organism that tries to adapt to the increase of the cardiac output and the peripheral resistance of the blood vessels, which is manifested by the increase in blood pressure figures. Physical activity has been shown to have a lower risk of hypertension compared to sedentary individuals. The daily stress these workers face predisposes them to suffer their manifestations as headache, muscle pain, fatigue, digestive disorders and constant elevations of blood pressure.

Introduction: The tracheobronchial injuries are usually fatal and some of the lucky people can reach emergency services without dying in the place of trauma. They can cause severe symptoms which can be lifetreathing. This type of injuries must been taken carefully and need to decide fast what treatment you going to give. Case report: We present a 53 years old patient who has been stabbed during a fight and got his trachea ruptured. His complaints shortness of breath and neck swelling. He can be treated conservatively with bronchoscopic and clinical evaluation. Discussion: Tracheobronchial injuries are life-threatening and the airway must be secured first. They can be treated conservatively in some cases. CT can be useful but fiberoptic bronchoscopy is the key in diagnosis. Conclusion: Although early treatment of tracheal lacerations is urgent surgery, it is reported that these injuries can be treated with conservative methods under appropriate conditions.

Introduction: Pancreatic pseudocysts (PPs) are mostly delayed complications of acute or chronic pancreatitis and trauma. Pancreatic pseudocysts are usually managed by supportive medical treatment without surgical procedure. All the surgical interventions (percutaneous, endoscopic or surgical approaches) are based on the location, size, symptoms, complications of the pancreatic pseudocyst and medical condition of the patients. Recently, laparoscopic cystogastrostomy has become most appropriate approach especially for retrogastric pancreatic pseudocysts. In this study, we would like to report results of laparoscopic anterior transgastric cystogastrostomy by using linear articulated endo GIA stapler (Covidien medium thick purple) and versa-lifter (versa lifter®, laparoscopic retractor, manufactured by protomedlabs, France) in 14 pancreatic pseudocysts patients. Methods: We retrospectively analyzed data of patients with pancreatic pseudocysts treated by laparoscopic anterior transgastric cystogastrostomy from September 2010 to October 2014. All of the patients were controlled for the recurrence of pancreatic pseudocysts in February 2017. Results: 14 patients with pancreatic pseudocysts were managed by laparoscopic anterior transgastric cysto-gastrostomy. Conversion was performed in only one patient (7%). There were no symptoms and signs of recurrence of pancreatic pseudocyst during on average 43.6 months follow up time. Conclusion: Laparoscopic cystogastrostomy by using articulated linear endo-GIA stapler and versa-lifter is a safe and effective method for management of appropriate retro-gastric pancreatic pseudocysts.

Background: Laparoscopic cholecystectomy (LC), is one of the most commonly performed surgical procedures worldwide, it is accepted as the gold standard in the treatment of symptomatic gallstones for its minimal invasiveness, less pain and early recovery. Purpose: To predict the difficulty of laparoscopic cholecystectomy in patients according to the recently published scoring system and select the difficult cases to be done by a senior surgeon. Patients: This is a prospective cohort study. This study took place Oct 6th University Hospital and Kasr El Aini Hospital, Cairo university; the study involved 120 patients admitted with calcular cholecystitis, arranged for laparoscopic cholecystectomy. Methods: Laparoscopic cholecystectomy after applying the scoring system. Results: In our study we found that age, sex and ultrasonographic data were significant predictive factors for assessment preoperatively difficult cases that will be operated upon. We found 14 patients above 50 years who scored to be difficult and very difficult were at outcome difficult, only three patients converted to open surgery over fifty. Conclusion: We can report that obese patient who were over fifty with history of previous upper abdominal surgery and ultrasonographic picture showed thick walled GB and pericholecystic collection had high risk of conversion. At this study scoring system was used for prediction of difficult laparoscopic cholecystectomy sensitivity was 93.75% and specificity was 52.94% of the scoring system at score 5 for prediction of easy or difficult laparoscopic cholecystectomy.

Introduction: Acute kidney injury (AKI) is one of the complications associated with severe COVID-19 infection, and it can present in up to 20% to 40% of the cases; of these, approximately 20% will require renal replacement therapy (RRT). Objective: To establish clinical and laboratory characteristics in a group of patients from Colombia with COVID-19 infection and AKI that received intermittent and prolonged RRT with the GENIUS® 90 technology in between March and July 2020. Design: Cross-sectional study. Results: 78.9% of participants were men and 21.1% were women. The main comorbidities were the following: Hypertension (65.3%), diabetes mellitus (38.9%), obesity (26.3%), cancer (5.3%), Chronic obstructive pulmonary disease (11.6%), cardiovascular disease (23.2%), active smoking (11.6%). 33.7% had chronic kidney disease (CKD) in the average serum creatinine on admission was 4.4 mg/dl. The following inflammatory markers were elevated: C-reactive protein (CRP), d-dimer and ferritin (20.3 mg/dl, 931mcg/l and 1174 ng/ml, respectively). 63.5% of patients underwent sustained low-efficiency dialysis (SLED) (6 to 12 hours) and the rest of the patients (36.35%) underwent conventional hemodialysis (less than 4 hours). The mortality of the total patient sample was 36.9%, lower in patients with CKD than in patients with no previous renal disease history (18.7% and 40.1%, respectively). Conclusion: Renal complications are frequent in patients with severe COVID-19. The development of AKI could be an isolated prognostic marker associated with an increase in mortality in patients with COVID-19, and one of the options is intermittent and prolonged RRT with the GENIUS® 90 system.
