Background: Laparoscopic cholecystectomy, one of the most common elective surgical procedures, is a minimally invasive surgical procedure for patients with gallbladder diseases. Objectives: This study aimed to evaluate the effect of laparoscopic cholecystectomy on coagulation tests among patients undergoing the surgery in Ali Ibn Abi Taleb Hospital in Zahedan. Methods: Following a quasi-experimental design, 21 cases scheduled for laparoscopic cholecystectomy for whatever reasons at Ali Ibn Abi Taleb Hospital in Zahedan (Iran) were selected. To study the serum levels of blood factors, blood samples were collected at three stages, i.e., before the surgery (time point 1), 30 minutes after pumping the carbon dioxide gas into the abdomen (time point 2), and 30 minutes after removing the last port from the abdomen (time point 3). Data were analyzed using repeated measures. Results: According to the findings, laparoscopic cholecystectomy surgery only had a significant effect on the PT coagulation factor at the 99% confidence level. Also, PT was increased and significantly differed at time points 2 (30 minutes after pumping) and 3 (30 minutes after removing the port) compared to time point 1 (30 minutes before the surgery). Conclusions: Generally, it can be argued that despite observing some variations in the PT coagulation factor during the laparoscopic surgery, the INR level did not change. Hence, it can be considered as a safe surgical intervention for renal and liver functions.

Abstract Background The purpose of this study was to assess the cytotoxicity of various concentrations of ozonated water (OW) on human primary dental pulp cells. Methods Human primary dental pulp cells were isolated from exfoliated primary canine teeth of an 11-year-old patient with good systemic and oral health. Afterwards, cells were divided into 6 experimental groups; four groups of OW in concentrations of 2 mg/L, 4 mg/L, 8 mg/L, and 16 mg/L, untreated control group, and cell culture without cells. Cytotoxicity was evaluated after exposure for 5-min exposure using Mosmann’s Tetrazolium Toxicity (MTT) assay at 0 h and 48 h time points. Data were analyzed using a repeated measures analysis of variance and Post-hoc tests were performed using Bonferroni correction for multiple comparisons. Results All experimental groups showed proliferation at 0 h time point. However, all groups also experienced a decrease in overtime at 48 h time point (p < 0.05). At both time points 2 mg/L OW showed the highest cell viability as well as proliferation. At 0 h time point, the increase in cell viability for all experimental groups was found statistically significant when compared to positive control group (p < 0.05). At 48 h time point, although 8 mg/L and 16 mg/L OW showed statistically significant reduction in compare to 0 h time point, 2 mg/L and 4 mg/L OW groups didn’t experience any statistically significant difference (p < 0.05). Conclusion Considering our findings, due to ozonated water's induced a higher proliferation rate of dental pulp cells, indicating their biocompatibility and a possible adjuvant on irrigating agent in regenerative endodontic procedures.

Bone is a frequent site of metastases in advanced cancers including lung, breast, prostate, kidney, or myeloma. Lesions are commonly located on the spine. Neoplastic invasion of the vertebral body can result in painful vertebral fractures, leading to disability and substantial morbidity. Percutaneous vertebroplasty is a minimally invasive surgical procedure used to treat spinal fractures due to osteolytic tumors. It could result in pain reduction or resolution in 80–90% of patients with fractures, and it improves stability. Although considered safe, vertebroplasty has been associated over the years with life-threatening complications. We have reported the case of a 55-year-old patient with lung adenocarcinoma, who underwent vertebroplasty for a pathological neoplastic fracture of L2. The procedure was complicated by a leak of cement into the systemic venous circulation, characterized by an 11-cm filament in the right heart chambers and multiple pulmonary emboli. To our knowledge, only one similar case was previously reported, involving an intracardiac cement filament longer than 10 cm. The data are scant, hence the importance of collecting and reporting possible complications about what is perceived as a rather safe procedure. The case highlights the need for a robust postprocedure imaging plan to detect complications, which can impact patients’ morbidity and survival.

AbstractDeep brain stimulation (DBS) is becoming an increasingly popular minimally invasive surgical procedure for various movement disorders, especially Parkinson’s disease. Different nuclei have been identified depending on patients’ symptoms, but the success or failure of the procedure depends on various other factors such as proper patient selection and risk-benefit analysis. While various techniques of anaesthesia including monitored anaesthesia care, conscious sedation and general anaesthesia are being used routinely, no clear-cut evidence exists as to the best technique for this procedure. This review article discusses the surgical procedure of DBS, devices currently available, perioperative anaesthetic concerns and techniques, effect of anaesthetic drugs on microelectrode recordings and macro-stimulation and associated complications.

The issue of brain magnetic resonance image exploration together with classification receives a significant awareness in recent years. Indeed, various computer-aided-diagnosis solutions were suggested to support radiologist in decision-making. In this circumstance, adequate image classification is extremely required as it is the most common critical brain tumors which often develop from subdural hematoma cells, which might be common type in adults. In healthcare milieu, brain MRIs are intended for identification of tumor. In this regard, various computerized diagnosis systems were suggested to help medical professionals in clinical decision-making. As per recent problems, Neuroendoscopy is the gold standard intended for discovering brain tumors; nevertheless, typical Neuroendoscopy can certainly overlook ripped growths. Neuroendoscopy is a minimally-invasive surgical procedure in which the neurosurgeon removes the tumor through small holes in the skull or through the mouth or nose. Neuroendoscopy enables neurosurgeons to access areas of the brain that cannot be reached with traditional surgery to remove the tumor without cutting or harming other parts of the skull. We focused on finding out whether or not visual images of tumor ripped lesions ended up being much better by auto fluorescence image resolution as well as narrow-band image resolution graphic evaluation jointly with the latest neuroendoscopy technique. Also, within the last several years, pathology labs began to proceed in the direction of an entirely digital workflow, using the electronic slides currently being the key element of this technique. Besides lots of benefits regarding storage as well as exploring capabilities with the image information, among the benefits of electronic slides is that they can help the application of image analysis approaches which seek to develop quantitative attributes to assist pathologists in their work. However, systems also have some difficulties in execution and handling. Hence, such conventional method needs automation. We developed and employed to look for the targeted importance along with uncovering the best-focused graphic position by way of aliasing search method incorporated with new Neuroendoscopy Adapter Module (NAM) technique.

Anterior basal (S8) segmentectomy is one of the most challenging procedures among the uncommon pulmonary segmentectomies because the surgeon has to identify dominant pulmonary vein branches located deep in the lung parenchyma. Moreover, with the uniportal thoracoscopic approach, the angulation of inserted surgical instruments via a single small incision is extremely limited, which causes technical difficulties. However, adoption of a suitable procedure such as unidirectional dissection enables us to perform this type of minimally invasive surgical procedure. We describe the successful results of a patient undergoing uniportal thoracoscopic S8 segmentectomy of the right lower lobe and explain the nuances of performing it.

Abstract Objectives Assess the effects of the amino acid arginine on growth hormone (GH), other metabolites, and mood. Arginine is reported to increase GH, but the mechanism is not known. It was hypothesized prolactin mediated this effect since it is similar in structure to GH and, like GH, is secreted by the pituitary gland. Methods Thirty physically active healthy young males (18–39 y; 18.5–25 kg/m2) were enrolled in a randomized, double-blind, placebo-controlled, crossover trial. Two days prior and 1 day following each treatment a standardized diet was provided that maintained arginine at 3–5 g/d. Arginine or placebo treatments in the form of a beverage were consumed after an overnight fast. Treatment conditions were separated by at least a one week washout period. The beverages contained either 10 g of arginine or 0 g (placebo). Blood was collected at baseline and 1.5, 3.0, and 24 hr post treatment. Plasma GH, prolactin, amino acids, glucose, insulin, triacylglycerols, thyroid hormones, sex hormone binding globulin (SHBG), testosterone, cortisol, and dehydroepiandrosterone (DHEA) were assessed. The Profile of Mood States (POMS) was administered at the same time as blood draws. Repeated measures ANOVAs were used to estimate treatment effects at each time point. Results Arginine increased plasma arginine at 1.5, 3.0, and 24 hr (P ≤ 0.001) and GH at 24 hr (P ˂ 0.05) but not other time points. Arginine increased glucose and insulin at the 1.5 and 3.0 hr (P ˂ 0.05) but not 24 hr. Arginine did not affect any other dependent measure (P &gt; 0.05) including prolactin. When only individuals with detectable levels of GH (responders; n = 16) were analyzed separately, arginine increased GH at the 1.5 (P ˂ 0.05) but not the 3.0 or 24 hr time points. Among the responders, arginine also increased thyroid stimulating hormone (TSH) at the 24 hr time point (P ˂ 0.05) but not the 1.5 and 3.0 hr time points. Conclusions Arginine supplementation modestly increased growth hormone. Despite their similar structures, prolactin secretion was not elevated following arginine supplementation, thus another mechanism is responsible for growth hormone secretion.

ABSTRACT: In face of the few reports found in national literature analyzing the potential influence of parturition number in serum proteinogram and biochemical profile in the peripartum period of high yielding dairy cows, the aim of the present study was to comparatively evaluate the dynamics of these serum constituents’ concentrations in blood samples obtained from primiparous and multiparous Holstein cows, 60 and 30 days prepartum and in the day of parturition. Data were analyzed by repeated measures variance analysis (ANOVA) and differences between groups and moments were analyzed by Tukey’s test. Results were considered significant when P<0.05. Parity influenced levels of total protein, albumin, globulins, magnesium, cholesterol, which were higher in multiparous cows, as well as concentrations of ceruloplasmin, total calcium, chloride and alkaline phosphatase activity, which were higher in primiparous cows. Parturition influenced serum concentrations of ceruloplasmin (+58%), transferrin (-25%), haptoglobin (+33%), total protein (-17%), globulins (-25%), immunoglobulin A (-43%), immunoglobulin G (-24%), total calcium (-12%), inorganic phosphorus (-10%), chloride (+5%), sodium (+4%), cholesterol (-23%), triglycerides (-38.6%), as well as activities of aspartate aminotransferase (+14%) and alkaline phosphatase (+28%). A decrease in serum levels of total calcium, inorganic phosphorus, cholesterol and triglycerides was more pronounced in multiparous than in primiparous cows. These results demonstrate that the interpretation of proteinogram and serum constituents should take into consideration lactation number and the moment of parturition as relevant factors in high yielding dairy cows in the transition period.

Abstract Background and Objectives Perceived discrimination is a risk factor for poor mental health. However, most studies measure discrimination at one time point, which does not account for heterogeneity in the cumulative patterning of exposure to discrimination. To address this gap, we examine the association between discrimination trajectories and depressive symptoms among black middle-aged and older adults. Research Design and Methods Data were analyzed from a subsample of black Health and Retirement Study respondents (2006–2018, N = 2926, older than 50 years). General discrimination and racial discrimination trajectories were constructed based on the Everyday Discrimination Scale using repeated measures latent profile analyses. We examined the extent to which the association between discrimination trajectories are differentially associated with depressive symptoms (8-item Center for Epidemiological Studies-Depression scale) using negative binomial regression models adjusted for potential confounders. Effect modification by age and gender was tested. Results Individuals in the persistently high (incident rate ratio [IRR]: 1.70; 95% confidence interval [CI]: 1.49–1.95) and moderate general discrimination trajectories (IRR: 1.19; 95% CI: 1.06–1.33) were more likely to have elevated depressive symptoms in comparison to those in the persistently low trajectory. This relationship was strongest among older adults aged older than 65 years. Respondents in the persistently high racial discrimination trajectory (IRR: 1.50; 95% CI: 1.29–1.73) had a higher risk of elevated depressive symptoms in comparison to respondents in the persistently low trajectory. Sensitivity analyses indicated that there was an independent association between persistently high racial discrimination trajectory class and elevated depressive symptoms, after adjusting for racial discrimination measured at a single time point. Discussion and Implications Characterizing longitudinal patterns of perceived discrimination may facilitate the stratification of mental health risk and vulnerability among black middle-aged and older adults. Trajectories of racial discrimination may inform risk of worse depressive symptoms more accurately than a single assessment of discrimination.

Caustic ingestion may cause devastating injuries of the upper gastrointestinal tract and the respiratory system. We report here the successful treatment of a 37-year-old patient who ingested hydrochloric acid (100 mL; 24%) in suicidal intention. An oesophagogastroduodenoscopy revealed extensive necrosis of the gastric mucosa. A diagnostic laparoscopy was performed and confirmed the suspected transmural necrosis which resulted in a discontinuous laparoscopic gastrectomy. During the next days, the oesophageal stump was monitored through frequent oesophagoscopies and showed a good recovery. Thus, it was possible to restore continuity as early as by the sixth postoperative day performing a roux-en-y oesophagojejunostomy using the da Vinci Xi surgical robot. The patient underwent all procedures without any surgical complications and was discharged almost 1 month after initial presentation in good general condition.
