Abstract
The synthesis of thioether derivatives has been explored widely due to the potential application of these derivatives in medicinal chemistry, pharmaceutical industry and material chemistry. Within this context, there has been an increasing demand for the environmentally benign construction of C-S bonds via C-H functionalization under metal-free conditions. In the present article, we highlight recent developments in metal-free sulfenylation that have occurred in the past three years. The synthesis of organosulfur compounds via a metal-free approach using a variety of sulfur sources, including thiophenols, disulfides, sulfonyl hydrazides, sulfonyl chlorides, elemental sulfur and sulfinates, is discussed. Non-conventional strategies, which refer to the development of thioether derivatives under visible light and electrochemically mediated conditions, are also discussed. The key advantages of the reviewed methodologies include broad substrate scope and high reaction yields under environmentally benign conditions. This comprehensive review will provide chemists with a synthetic tool that will facilitate further development in this field.

Abstract
Background Recent evidence on the cost-effectiveness of technology in total knee arthroplasty (TKA) demonstrated that navigated computer-assisted methods (N-TKA) is likely to be most cost-effective in the clinical setting. The aim of the current meta-analysis is to compare radiographic, clinical and functional outcomes between conventional TKA (C-TKA) and N-TKA methods. Methods All prospective randomized controlled trials (pRCTs) comparing primary TKA performed using C-TKA and N-TKA techniques were eligible for inclusion. Radiographic outcomes included postoperative coronal, sagittal and axial component alignment. Clinical outcomes included all-cause revision and aseptic revision. Functional outcomes were analyzed when reported. A random-effects meta-analysis of all available cases was performed. This allowed for all missing data. Results Normal coronal mechanical alignment of the tibial (p < 0.001) and femoral (p = 0.001) components was achieved more frequently with N-TKA. Normal sagittal mechanical alignment of the tibial component was achieved significantly more with N-TKA (p < 0.010). There was no difference in short-term clinical survivorship (all-cause, p = 0.649; aseptic, p = 0.79) or in functional outcomes reported between groups. There was a clinically significant reduction in the mean C-TKA operative time (87 min, σ = 16.6, 95% CI 76.4-98.8) compared N-TKA (97.6 min, σ = 16.9, 95% CI 86.2-109.1) (p = 0.17). Conclusion Navigated TKA achieves superior radiographic alignment for femoral and tibial components in both the coronal and sagittal plane. Operative times are 10 min longer in the N-TKA group. Functional outcomes are similar between navigated and conventional groups. Clinical outcomes reported in Level I studies are limited to short-term follow-up so future prospective studies are required.

Abstract
Background Computer- and robotic-assisted total knee replacement procedures have been shown to improve the accuracy of the implant size. It also allows dynamic confirmation of the implant and limb alignment during total knee arthroplasty (TKA). The major inhibition of the arthroplasty surgeon in adapting to the robotic-assisted TKA (RA-TKA) is the extra time spent during the registration process and milling of the bone with the robot. The aim of the study was to ascertain the extra time spent during these 2 steps as compared to the conventional TKA (C-TKA). Methods It is a prospective study involving 30 patients each in the conventional TKA and RA-TKA operated by the same surgical team. The patients were given a choice between the C-TKA and RA-TKA and consecutive 30 cases in each group were studied by an independent observer. In the C-TKA group, the time for the application of appropriate zigs and execution of the bone cuts and soft-tissue release was recorded whereas in the RA-TKA group, the time taken for fixation of the tibial and femoral arrays and bone registration and bone milling with robot and required soft-tissue release was measured. Results The preoperative patient characteristics were the same in both groups. The time taken in the C-TKA and RA-TKA groups was 24.77 ± 1.92 minutes and 25.03 ± 3.27 minutes, respectively, which is statistically insignificant (p = 0.709). Conclusions The study findings show that RA-TKA does not take additional time than C-TKA.

Abstract
Background Robotic-assisted systems have gained popularity in total knee arthroplasty (TKA). The purpose of this study was to evaluate operative characteristics and radiographic outcomes of obese patients undergoing robotic-assisted TKA. Methods A retrospective review of consecutive cases performed by a single surgeon was performed from January 1, 2016, to January 31, 2022. Adult patients with body mass index ≥35 kg/m2 who underwent primary TKA using a computed tomography-assisted robotic system were compared to patients who underwent primary TKA using conventional instrumentation. Demographics, preoperative and postoperative radiographic measurements, and intraoperative outcomes were compared between cohorts. In total, 119 patients were identified, 60 in the robotic-assisted cohort and 59 in the conventional instrumentation cohort. Results Age, body mass index, and estimated blood loss were not significantly different between the cohorts. The robotic-assisted cohort experienced longer tourniquet times (93.3 vs 75.5 minutes, P < .001). Preoperative hip-knee-ankle angle (HKA) was similar between the robotic-assisted and conventional cohorts (8.4° ± 4.9° vs 9.3° ± 5.3°, P = .335). Postoperative HKA was 2.0° ± 1.4° in the robotic-assisted group and 3.1° ± 3.23° in the conventional group (P = .040). The proportion of patients with postoperative HKA > 3° of varus or valgus was 9 of 60 (15.0%) in the robotic-assisted cohort compared to 18 of 59 (30.5%) using conventional instrumentation (P = .043). Conclusions Obese patients treated with robotic-assisted TKA had postoperative alignment closer to neutral and fewer postoperative radiographic outliers than patients treated with conventional instrumentation. The results of this study support use of robotic-assisted technologies in TKA, particularly in obese patients.

Abstract
PURPOSE Joint line (JL) position change in total knee arthroplasty (TKA) may alter knee biomechanics and impact function. The purpose of this study was to compare the change in JL position between robotic-assisted TKA (RA-TKA) and conventional TKA (C-TKA). METHODS A retrospective, radiographic analysis was conducted of patients who underwent RA-TKA and C-TKA to compare JL position change. JL position was measured in consecutive RA-TKAs and C-TKAs performed by four fellowship-trained arthroplasty surgeons. Statistical analysis was done utilizing t-tests and Mann Whitney U tests, with statistical significance being defined as a p value < 0.05. RESULTS Six hundred total RA-TKAs and 400 total C-TKAs were included in the analysis. There were no significant differences in patient baseline characteristics such as body mass index, range of motion, and tibiofemoral coronal alignment. RA-TKAs were associated with an average of 0.04 (2.2) mm JL position change, and C-TKAs were associated with an average 0.5 (3.2) mm JL position change (p = 0.030). There were inter-surgeon differences when comparing the change in JL position for RA-TKAs and C-TKAs between the four participating surgeons. CONCLUSION RA-TKA leads to better preservation of the JL position than C-TKA, and this seems to be dependent on the arthroplasty surgeon's preferences and techniques during TKA. Whether this statistically significant difference is clinically relevant needs to be further investigated.

Abstract
Pheniramine is an over-the-counter antihistamine drug. Its accessibility and low cost made it more popular among drug abusers in Pakistan. In this study, pheniramine was quantified in both conventional and alternative specimens of twenty chronic drug abusers, aged 16-50 years, who were positive for pheniramine in comprehensive toxicological screening for drugs by gas chromatography with mass spectral detection in positive electron impact mode. Pheniramine was extracted from biological specimens using solid phase extraction and liquid chromatography tandem mass spectrometry was employed for quantification. Chromatographic separation was carried out on a Poroshell120EC-18 (2.1 mm × 50 mm × 2.7 µm) column using water-acetonitrile in formic acid (0.1%) mobile phase in gradient elution mode with 500 μL/min flow rate. Positive electrospray ionization mode and multi-reaction monitoring with ion transitions m/z 241.3 → 195.8 and 167.1 for pheniramine and m/z m/z 247.6 → 173.1 for pheniramine-d6 were employed. The quantification method showed good linear ranges of 2-1000 ng/mL in blood, urine, and oral fluid; 2-1000 ng/mg in hair and 5-1000 ng/mg in nail with ≥ 0.985% coefficient of linearity. The retention time of pheniramine was 3.0 ± 0.1 min. The detection and lower quantification limits were 1 ng/mL and 2 ng/mL for blood, urine, oral fluid and hair whereas 2.5 ng/mg and 5 ng/mg for nail, respectively. Mean extraction recovery and ionization suppression ranged 86.3-95.1% and -4.6 to -14.4% in the studied matrices. Intra-day and inter-day precision were 4.1-9.3% and 2.8-11.2%, respectively. Pheniramine levels in specimens of drug abusers were 23-480 ng/mL in blood, 72-735 ng/mL in urine, 25-379 ng/mL in oral fluid, 10-170 ng/mg in hair and 8-86 ng/mg in nail specimens. Alternative specimens are of utmost significance in clinical and medico-legal cases. In this study, authors compared matrix-matched calibration curves to blood calibration curve and obtained results within ± 10%; thereby justifying the use of blood calibration curve for urine, oral fluid, hair, and nail specimens.

Abstract
INTRODUCTION AND IMPORTANCE Chondrosarcoma is a rare malignant tumor considered as the second common sarcoma of bone following osteosarcoma. Less than 5 % of chondrosarcomas occur in children. Conventional chondrosarcoma is the most common type observed as skeletal tumors. Extraskeletal chondrosarcomas account for about 1 % of chondrosarcomas. They are almost always of myxoid or mesenchymal subtypes. CASE PRESENTATION A 4-year-old girl was referred with pain and palpable mass in the labia majora since 2 years of age for which she had undergone twice biopsies, reported as soft tissue enchondroma. At this time, complete excision of the lesion with negative margins was carried out. The pathology was in favor of extraskeletal chondrosarcoma of conventional type without any evidence of bone involvement. CLINICAL DISCUSSION Our case was a very young child with extraskeletal conventional chondrosarcoma, not reported yet in the literature. The vast majority of extraskeletal myxoid chondrosarcomas arise in the soft tissues of the extremities. The lesion in this case was located within the subcutaneous tissue of the labia majora; however, the tumor was not compatible with myxoid chondrosarcoma. Mesenchymal chondrosarcoma is another type of extraskeletal chondrosarcoma but the histopathologic patterns observed in our patient were not compatible even with the mesenchymal chondrosarcoma. CONCLUSION We present a unique case of extraskeletal chondrosarcoma in a child with conventional subtype which has not been reported in the literature. In addition, the lesion was assumed to arise from a previous soft tissue enchondroma of the labia majora since infancy which makes the case distinctive.

Abstract
BACKGROUND Bacterial infections are becoming difficult to treat nowadays due to the development of resistance towards conventional treatments. Conventional topical formulations loaded with antibiotics display various disadvantages, like high dosing frequency, high toxicity, and poor patient compliance. The former limitations may sometimes lead to severe complications and hospitalization of patients. However, these can be overcome by employing vesicular nanocarriers for the delivery of antibiotics following the topical/transdermal route. OBJECTIVE The objective of this review paper was to summarize the role of vesicular nanocarriers, like liposomes, elastic liposomes, niosomes, ethosomes, solid lipid nanoparticles, nanostructured lipid carriers, and nanoemulsions for topical/transdermal delivery of antibiotics, and patents associated with them. METHODS Literature for the present review was collected using various search engines, like PubMed, Google Scholar, and Google Patents. RESULTS Various literature investigations have revealed the in vitro and preclinical efficacy of vesicular nanocarrier systems in the delivery of antibiotics following the topical/transdermal route. CONCLUSION Vesicular nanocarrier systems, via targeted delivery, may subside various side effects of antibiotics associated with conventional delivery, like high dosing frequency and poor patient compliance. However, their existence in the pharmaceutical market will be governed by effective clinical assessment and scale-up methodologies.

Abstract
The craving for organic cocoa beans has resulted in fraudulent practices such as mislabeling, adulteration, all known as food fraud, prompting the international cocoa market to call for the authenticity of organic cocoa beans before export. In this study, we proposed robust models using laser-induced fluorescence (LIF) and chemometric techniques for rapid classification of cocoa beans as either organic or conventional. The LIF measurements were conducted on cocoa beans harvested from organic and conventional farms. From the results, conventional cocoa beans exhibited a higher fluorescence intensity compared to organic ones. In addition, a general peak wavelength shift was observed when the cocoa beans were excited using a 445 nm laser source. These results highlight distinct characteristics that can be used to differentiate between organic and conventional cocoa beans. Identical compounds were found in the fluorescence spectra of both the organic and conventional ones. With preprocessed fluorescence spectra data and utilizing principal component analysis, classification models such as Linear Discriminant Analysis (LDA), Support Vector Machine (SVM), Neural Network (NN) and Random Forest (RF) models were employed. LDA and NN models yielded 100.0% classification accuracy for both training and validation sets, while 99.0% classification accuracy was achieved in the training and validation sets using SVM and RF models. The results demonstrate that employing a combination of LIF and either LDA or NN can be a reliable and efficient technique to classify authentic cocoa beans as either organic or conventional. This technique can play a vital role in maintaining integrity and preventing fraudulent practices in the cocoa bean supply chain.

Abstract
Ocular hypertension is caused by dysregulated outflow resistance regulation by the conventional outflow (CO) pathway. The physiology of the CO pathway can be directly studied during ex vivo ocular perfusions. In addition to measuring outflow resistance generation by the CO tissues, perfusion media that is conditioned by CO pathway cells can be collected upon exiting the eye as effluent. Thus, contents of effluent include factors contributed by upstream cells that report on the (dys)functionality of the outflow tissues. Two methods have been used in the past to monitor effluent contents from perfused eyes, each with their limitations. To overcome these limitations, we designed and printed a metabolic chamber to accommodate eyes of different sizes during perfusions. To test this new chamber, human eyes were perfused for 4 h at constant flow rate of 2.5 μl/min, while pressure was continuously monitored and effluent was collected every hour. Facility was 0.28 ± 0.16 μl/min/mmHg for OD eyes and 0.33 ± 0.11 μl/min/mmHg for OS eyes (n = 3). Effluent samples were protein rich, with protein concentration ranging from 2700 to 10,000 μg/ml for all eyes and timepoints (N = 3). Effluent samples expressed proteins that were actively secreted by the TM and easily detectible including MYOC and MMP2. Taken together, our model provides a reliable method to collect effluent from ex vivo human eyes, while maintaining whole globe integrity.

Abstract
PURPOSE Robotic-assisted total knee arthroplasty (R-TKA) has emerged as an alternative to improve the results of the conventional manual TKA (C-TKA). The aim of this study was to analyse the high-level studies comparing R-TKA and C-TKA in terms of clinical outcomes, radiological results, perioperative parameters, and complications. METHODS The literature search was conducted on three databases (PubMed, Cochrane, and Web of Science) on 1 February 2023 according to the guidelines for Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Inclusion criteria were: randomized controlled trials (RCTs), written in English language, published in the last 15 years, focusing on the comparison of C-TKA and R-TKA results. The quality of each article was assessed using the Cochrane risk-of-bias tool for randomized trials version 2 (RoB 2). The statistical analysis was carried out using random effects (DerSimonian & Laird) for weighted mean difference (MD) of the continuous variables and Peto method for odds ratios of the dichotomous variables. RESULTS Among the 2905 articles retrieved, 14 RCTs on 12 series of patients treated with mechanically aligned implants were included. A total of 2255 patients (25.1% males and 74.9% females; mean age 62.9 ± 3.0; mean BMI 28.1 ± 1.3) were analysed. The results of this systematic review and meta-analysis showed that R-TKA did not provide overall superior results compared to C-TKA in mechanically aligned implants in terms of clinical and radiological outcomes. R-TKA showed longer operative time (MD = 15.3 min, p = 0.004) and similar complication rates compared to C-TKA. A statistically significant difference in favour of R-TKA was found in the posterior-stabilized subgroup in terms of radiological outcomes (hip-knee-ankle angle MD = 1.7, p < 0.001) compared to C-TKA, although without resulting in appreciable difference of clinical outcomes. CONCLUSION R-TKA did not provide overall superior results compared to C-TKA in terms of clinical and radiological outcomes, showing longer operative time and similar complication rates. LEVEL OF EVIDENCE Level I.

Abstract
While anthelmintic treatment in young calves at first vaccination has not proven repeatedly effective in improving weight gain, there is evidence that treatment 90 day prior to weaning can enhance weight gain. This is difficult in most California cow/calf operations as after initial vaccination, calves are not again handled until preconditioning just prior to weaning. In an attempt to increase weight gain without the need for anthelmintic retreatment prior to preconditioning, 130 cow/calf pairs were stratified and assigned to three treatments of eprinomectin extended release injection (150 d efficacy), doramectin conventional injection, and an untreated control. Dams and calves received the same treatment. All treatments were commingled on irrigated pasture in Northern California. Sampling included weight (d 0, 75, and 145), fecal parasite (d 0, 14, 75, and 145), cow body condition score (d 0, 75, and 145), and cow pregnancy detection (days bred). Calf weight gain was not impacted by anthelmintic treatment (P = 0.44). However, cow weight gain was impacted by treatment (P < 0.01), with eprinomectin extended release showing higher weight gain than both doramectin conventional and the control (ADG kg 0.29, 0.23, 0.22, respectively). Cow weight gain differences were expressed greater toward the end of the trial than early on. Fecal egg count sampling failed to explain the difference in cow weight gain. Cow body condition score (P = 0.15) and days bred (P = 0.50) were not significantly affected by treatment. Although cow weight gain increased with an extended release anthelmintic treatment, this effect did not seem to be evident in suckling calves on high quality irrigated pastures in Northern California when compared to a conventional injectable and control treatments. Neither anthelmintic treatment appeared beneficial over a control when administered to suckling calves during initial vaccination at approximately 90 days of age.

Abstract
OBJECTIVES The objective of this review was to present a thorough overview of the complications associated with conventional percutaneous sacroiliac screw fixation to identify areas for improvement in surgical technique and patient selection. METHODS PubMed/Medline, Web of Science, Embase, Ovid, Cochrane library, and Google Scholar were systematically searched for original human studies reporting on complications of conventional percutaneous sacroiliac fixation in traumatic pelvic ring injuries from January 1, 2000, to April 30, 2022. The main meta-analysis was based on the random effect model to pool all complications reported in the included studies. The results were reported as weighted proportions with 95% confidence intervals. This review was conducted in line with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. RESULTS A total of 56 studies with 3644 screws (2871 procedures) met the inclusion criteria, with a mean age of 40.5 years. The most frequently reported complications were screw malposition with a weighted proportion of 6% (95% CI: 5-9%) and involved 189 out of 3644 screws, persistent pain following the procedure with a weighted proportion of 3% (95% CI: 2-4%) and affected 98 out of 2871 patients, and nerve injury, which had a weighted proportion of 2% (95% CI: 1-3%) and was observed in 41 out of 2871 procedures. The L5 and S1 nerve roots were more frequently affected. Revision surgery was required for 184 out of 2871 patients with a weighted proportion of 5% (95% CI: 3-7%). The primary reason for the revision was persistent pain after the initial procedure, which affected 74 out of 184 patients, with a weighted proportion of 2.0% (95% CI: 1.2-2.8%). CONCLUSIONS This study showed that screw malposition, the need for revision surgery, persistent pain, and nerve injuries were the most frequent complications following conventional percutaneous sacroiliac screw fixation. However, these results must be interpreted in context due to confounding factors, including the lack of high-quality studies and the absence of uniformity in defining some complications across studies.

Abstract
Background Liquid-based cytology (LBC) can improve adequacy, monolayer quality with a clean background compared to conventional smears (CS). Aims and Objectives The objective was to compare the quality and diagnostic yield of CS and LBC in routine cytological investigations. Materials and Methods This retrospective study consisted of 306 samples (255 gynecological, 39 nongynecological, and 12 fine needle aspiration cytology [FNAC]) during a 2-year period (2019-2020). From each patient, two samples were collected in the same manner in the same sitting and processed by CS and LBC (ThinPrep® 2000, Hologic Inc.). Both CS and LBC were compared for adequacy, quality, representativeness, inflammation, hemorrhage, necrosis, preservation, reactive changes, organisms, atypia/dysplasia/malignancy, and preparation/screening time. Statistical analysis was performed. Results No statistically significant difference was noted for adequacy, representativeness, reactive changes, preservation, and atypia/dysplasia/malignancy. CS was better in cellularity and diagnosis of inflammation and organisms, whereas LBC had a clean background and the difference was statistically significant (P = 0.0005). Conclusions CS was equivalent to LBC in adequacy, representativeness, reactive changes, and atypia/dysplasia/malignancy. Adequacy comparable to LBC can be achieved in CS by careful sample collection, processing, and screening by trained cytotechnologists. CS was better in detecting organisms and inflammation than LBC. The advantages of LBC were monolayer smear, clean background, and lesser screening time, but the demerit was higher cost and longer processing time. Therefore, LBC is best suited to those laboratories having high sample inadequacy rates, lack of competent cytotechnologists, and no financial constraints. Either man or machine, appropriate and adequate sample collection by trained personnel forms the cornerstone for ensuring adequacy in both CS and LBC.

Abstract
The most common cause of nasal obstruction is a deviated nasal septum. It causes breathing difficulties and may eventually also cause sinusitis, epistaxis, sleep disturbances and snoring. The traditional surgeries of the nasal septum improve the nasal airway but do not fulfil the essential criteria in most instances. Endoscopic septoplasty is a fast-developing concept and gaining popularity as it provides a direct targeted approach to the septal anatomic deformity allowing a minimally invasive procedure under excellent visualization. The aim of this study is to compare the post-operative morbidity among conventional and endoscopic septoplasty. The present prospective study was conducted on 50 patients having deviated nasal septum. Patients were randomly divided into two groups of 25 each. Out of 50 patients, in 25 patients (Group A) Conventional septoplasty was done, whereas in other 25 patients (Group B) endoscopic septoplasty was done. The patients were followed up post-operatively at 2 weeks, 4 weeks and 8 weeks. Study Design: comparative study. The mean of operating time (min) in Group A was 60.47 ± 8.16 which was significantly higher as compared to Group B (39.7 ± 6.73). (p value < .0001). The Mean of blood loss (mL) was significantly higher in Group A (88.67 ± 8.77) as compared to Group B. (54.6 ± 7.18). (p value < .0001). Post-operative NOSE score at one month was 7.33 ± 1.5 in group A which was significantly higher as compared to Group B (5 ± 1.41). (p value = 0.0007) whereas post-operative NOSE score at 3 months in Group A was 6.53 ± 1.25 which was significantly higher as compared to Group B (4.4 ± 1.78). Proportion of post-operative complications was comparable in Group A and Group B (No complication 80% vs. 92% respectively). According to the present study, both the conventional and endoscopic septoplasty procedures were effective in relieving nasal obstruction in the patients. Endoscopic septoplasty showed significantly better result than conventional septoplasty in terms of time taken for surgery, blood loss during the surgery, post-operative complications and in terms of quality of life as assessed by NOSE Score.

Abstract
BACKGROUND Squamous verrucous proliferative lesions of oral cavity can pose a diagnostic challenge for the general pathologist, especially on small biopsies. The superficial nature of incisional biopsies and inconsistent histologic terminologies used for these lesions contribute to often-discrepant clinical diagnosis, resulting in delayed treatment. This study aims to explore the proliferative squamous lesions of oral cavity, correlate biopsy & resection diagnoses, and evaluate possible reasons for discrepant diagnosis (if any). DESIGN A retrospective review of oral verrucous squamous lesions was undertaken. Pathology database was searched for oral cavity biopsies from January2018 through August2022 with the keywords: atypical, verrucous, squamous, and proliferative. Cases with follow-up were included in this study. A blinded review of the biopsy slides was performed and documented by a single head and neck pathologist. Demographic data, biopsy and final diagnosis were recorded. RESULTS Twenty-three cases met criteria for inclusion. The mean patient age was 61.1 years with a male: female ratio of 1.09. Most frequent site was lateral border of tongue (36%) followed by buccal mucosa and retromolar trigone. The most common biopsy diagnosis was "Atypical squamoproliferative lesion, excision recommended" (n = 16/23, 69%) with 13/16 showing conventional squamous cell carcinoma (SCC) on follow-up resection. 2/16 atypical cases underwent repeat biopsy for confirmation of diagnosis. Overall, conventional SCC was the most prevalent final diagnosis (73%, n = 17), followed by verrucous carcinoma (17%, n = 4). On slide review, six initial biopsies were reclassified as SCC, while one final diagnosis was reclassified as a hybrid carcinoma (on resection specimen). Diagnostic concordance (biopsy and resection) was observed in three cases, all three were recurrences. The primary reasons for discrepant diagnosis on initial biopsies were found to be 1. Obscuring inflammation, 2. Superficial biopsies, and 3. Under recognition of morphologic features (e.g., tear shaped rete, loss of polarity, dyskeratotic cells, paradoxical maturation) that help differentiate dysplasia from reactive atypia. CONCLUSION This study highlights the rampant interobserver variability in diagnosis of oral cavity squamous lesions and emphasizes importance of identifying morphologic clues that can aid in correct diagnosis, thereby helping in adequate clinical management.

Abstract
Legumes such as peanut (Arachis hypogea) can fulfill most of their nitrogen requirement by symbiotic association with nitrogen-fixing bacteria, rhizobia. Nutrient availability is largely determined by microbial diversity and activity in the rhizosphere that influences plant health, nutrition, and crop yield, as well as soil quality and soil fertility. However, our understanding of the complex effects of microbial diversity and rhizobia inoculation on crop yields of different peanut cultivars under organic versus conventional farming systems is extremely limited. In this research, we studied the impacts of conventional vs. organic cultivation practices and inoculation with commercial vs. single strain inoculum on peanut yield and soil microbial diversity of five peanut cultivars. The experiment was set up in the field following a split-split-plot design. Our results from the 16 S microbiome sequencing showed considerable variations of microbial composition between the cultivation types and inoculum, indicating a preferential association of microbes to peanut roots with various inoculum and cropping system. Alpha diversity indices (chao1, Shannon diversity, and Simpson index) of soil microbiome were generally higher in plots with organic than conventional inorganic practices. The cultivation type and inoculum explained significant differences among bacterial communities. Taxonomic classification revealed two phyla, TM6 and Firmicutes were significantly represented in inorganic as compared to organic soil, where significant phyla were Armatimonadetes, Gemmatimonadetes, Nitrospirae, Proteobacteria, Verrucomicrobia, and WS3. Yields in the organic cultivation system decreased by 10-93% of the yields in the inorganic cultivation system. Cultivar G06 and T511 consistently showed relative high yields in both organic and inorganic trials. Our results show significant two-way interactions between cultivation type and genotype for most of the trait data collected. Therefore, it is critical for farmers to choose varieties based on their cultivation practices. Our results showed that bacterial structure was more uniform in organic fields and microbial diversity in legumes was reduced in inorganic fields. This research provided guides for farmers and scientists to improve peanut yield while promoting microbial diversity and increasing sustainability.

Abstract
Very low-head water facilities are the salient resources for the development of hydropower using non-conventional hydro turbines. This review paper is concentrated on the collection and selection of turbines suitable for hydraulic heads between 0.5 and 3 m only defining them as the ultra-low-head. Turbines reviewed are feasible for new or existing infrastructure, drinking or waste-handled water, and able to function as a single unit, or parallel unit installation. From several earlier research and communication with 25 turbine manufacturers, thirty-eight different hydro turbines are discussed in this review with their operating range in most cases. The novelty of this review includes providing a comprehensive explanation of all the non-conventional hydropower turbines which were scattered in different literatures and providing a selection chart for classification of turbines. The distinct chart with four classification bases for hydro-static energy conversion of ultra-low-head turbines has been concluded and launched the category 'mode of action' to be the most comprehensive. The existing literature cover different basis for the selection but includes only few nonconventional turbines. This enforces the development of a specific selection chart comprising all such turbines with global scenarios.

Abstract
The current study's primary aim is to compare the safety and effectiveness between total and conventional robot-assisted cyst excisions and hepaticojejunostomies in children with choledochal cysts (CCs). Patients suffering from CCs treated with either total or conventional robot-assisted procedures (TRAS or CRAS) between December 2019 and February 2021 were analyzed retrospectively. Data collected included the characteristics, operative and postoperative details. The risk factors for conversion of TRAS to CRAS were analyzed by logistic regression analysis. There were 50 patients who underwent TRAS and CRAS, respectively, and 19 patients were transferred to CRAS. The operation time in the TRAS group was significantly higher than that of the CRAS group, while the time to taking water and hospital stay were significantly shorter (p < 0.05). No significant difference was observed in complications between the groups (p = 0.325). The risk factors for conversion of TRAS to CRAS were age ≥ 48 months, thickness of abdominal wall (TAW) ≥ 1.3 cm and upper abdominal length (UAL) ≥ 9.5 cm. Both TRAS and CRAS are safe and feasible. Performing TRAS is recommended for patients whose age ≥ 48 months, TAW ≥ 1.3 cm and UAL ≥ 9.5 cm, while for others, it is recommended to perform CRAS.

Abstract
BACKGROUND Nitrogen is very important for crop yield and quality. Crop producers face the challenge of reducing the use of mineral nitrogen while maintaining food security and other ecosystem services. The first step towards understanding the metabolic responses that could be used to improve nitrogen use efficiency is to identify the genes that are up- or downregulated under treatment with different forms and rates of nitrogen. We conducted a transcriptome analysis of barley (Hordeum vulgare L.) cv. Anni grown in a field experiment in 2019. The objective was to compare the effects of organic (cattle manure) and mineral nitrogen (NH4NO3; 0, 40, 80 kg N ha-1) fertilizers on gene activity at anthesis (BBCH60) and to associate the genes that were differentially expressed between treatment groups with metabolic pathways and biological functions. RESULTS The highest number of differentially expressed genes (8071) was found for the treatment with the highest mineral nitrogen rate. This number was 2.6 times higher than that for the group treated with a low nitrogen rate. The lowest number (500) was for the manure treatment group. Upregulated pathways in the mineral fertilizer treatment groups included biosynthesis of amino acids and ribosomal pathways. Downregulated pathways included starch and sucrose metabolism when mineral nitrogen was supplied at lower rates and carotenoid biosynthesis and phosphatidylinositol signaling at higher mineral nitrogen rates. The organic treatment group had the highest number of downregulated genes, with phenylpropanoid biosynthesis being the most significantly enriched pathway for these genes. Genes involved in starch and sucrose metabolism and plant-pathogen interaction pathways were enriched in the organic treatment group compared with the control treatment group receiving no nitrogen input. CONCLUSION These findings indicate stronger responses of genes to mineral fertilizers, probably because the slow and gradual decomposition of organic fertilizers means that less nitrogen is provided. These data contribute to our understanding of the genetic regulation of barley growth under field conditions. Identification of pathways affected by different nitrogen rates and forms under field conditions could help in the development of more sustainable cropping practices and guide breeders to create varieties with low nitrogen input requirements.

Abstract
PURPOSE This study aimed to examine the prosthetic orientations, limb alignment, intraoperative soft tissue balance, and early clinical outcomes associated with the use of the relatively new handheld robot technique compared to those associated with the use of the conventional alignment guide for bi-cruciate stabilized total knee arthroplasty (TKA). METHODS This retrospective cohort study compared the prosthetic orientation and limb alignment of 35 patients who underwent TKA using robotic assistance (robot group) with those of patients who underwent TKA using a conventional alignment guide (control group). The coronal femoral component alignment (FCA), coronal tibial component alignment (TCA), and the hip-knee-ankle (HKA) angle were compared between groups. Intraoperative soft tissue balance, including the joint component gap and varus/valgus balance assessed by an offset-type tensor, were also compared between groups. One year postoperatively, the clinical outcomes, including the range of motion and 2011 Knee Society Score (KSS), were compared between groups. RESULTS The HKA angle and FCA were 0.1° varus and 0.1° varus, respectively, in the robot group and 1.3° varus and 1.3° varus, respectively, in the control group. The difference in the HKA angle and the FCA, but not the TCA, between groups was statistically significant (p < 0.05). The intraoperative soft tissue balance showed more stable joint component gaps and varus/valgus balances throughout the range of motion in the robot group than in the control group. Clinical outcomes of the robot group showed superior 2011 KSS subscales compared to those of the control group. CONCLUSION The accuracy of the implantations and stable soft tissue balance in the robot group were superior to those of the control group. The robot group also had superior patient-reported scores for early clinical outcomes.

Abstract
Background Computer-assisted surgery, including robotic and navigational total knee arthroplasty (TKA), has been proposed as a technique used to improve alignment of implants. The purpose of this study was to compare the clinical and radiological outcomes during a minimum follow-up period of 10 years among robotic, navigational, and conventional TKA. Methods A total of 855 knees (robotic group, 194; conventional group, 270; and navigational group, 391) were available for physical and radiological examinations over a mean follow-up period of 10 years. The survival rate was analyzed using the Kaplan-Meier method based on the survival endpoint. The Hospital for Special Surgery score, Western Ontario and McMaster Universities Osteoarthritis Index, Knee Society Score, and range of motion were used for clinical evaluation. The hip-knee-ankle (HKA) axis angle, the coronal inclination of femoral and tibial components, and the presence of radiolucent lines were also assessed at the final follow-up. Results All clinical assessments at the final follow-up revealed improvements in the three groups without any significant difference among the groups (p > 0.05). The cumulative 10-year survival rate was 97.4% in the robotic group, 96.6% in the conventional group, and 98.2% in the navigational group, with no significant difference (p = 0.447). The rates of complication-associated surgery were not significantly different among the groups (p = 0.907). Only the proportion of outliers in the HKA axis angle showed a significant difference (p = 0.001), but other radiological outcomes were not significantly different among the three groups. Conclusions Our study demonstrated satisfactory survival rates for robotic, navigational, and conventional TKAs and similar clinical outcomes during the long-term follow-up. Larger studies with continuous serial data are needed to confirm these findings.

Abstract
AIM To compare the operating time, postoperative pain, edema, trismus, and patient acceptance following surgical removal of impacted third molar using piezosurgery and conventional rotary technique. MATERIALS AND METHODS About 42 patients with impacted mesioangular mandibular third molars were included in this study. Subjects are divided into two groups: group I (treated with conventional rotary technique) and group II (treated with piezosurgery). Duration of surgery, pain, trismus, and swelling were assessed. The patients were evaluated on the 1st, 3rd, and 7th postoperative days. RESULTS Postoperative pain, trismus, and edema were reduced with piezosurgery compared with conventional technique. Even though the duration of time was longer with piezosurgery, patient comfort was found to be better. CONCLUSION Piezosurgery is a meticulous and innovative ultrasonic technique with selective bone cutting and better postoperative outcomes. However, it is expensive, and the operating time is prolonged. CLINICAL SIGNIFICANCE Piezosurgery is an alternative in the surgical removal of third molars as it ensures precise and selective cutting, with no injury to the surrounding soft tissues. Postoperative outcome and patient acceptance are improved with piezosurgery.

Abstract
Tonsillectomy is still surrounded by controversy, especially regarding choice of surgical technique. Despite numerous surgical techniques are present, post-operative pain remains significant postoperative morbidities. An ideal method would lessen complications and minimize operative time and costs. This is a randomized double blinded interventional study. We enrolled 70 subjects and divided into two groups of 35 subjects in each. One group underwent traditional tonsillectomy and another underwent coblation tonsillectomy. We compared operating time, intraoperative blood loss, post-operative pain, return to normal activities and diet and post-operative hemorrhage. Mean operating time in coblation group was 18.24 ± 5.37 min and in traditional group 30.04 ± 7.08 min. The mean blood loss in coblation tonsillectomy group was 82.79 ± 21.13 ml and in traditional tonsillectomy 150.4 ± 37.91 ml. The mean of post-operative pain score in coblation tonsillectomy group was 3.2 ± 1.47 and in traditional tonsillectomy group 6.11 ± 1.61. The mean day of regaining activity in coblation tonsillectomy group was 6.26 ± 0.92 days and in traditional tonsillectomy group 8.26 ± 1.09 days. Mean time by which patients of coblation tonsillectomy group regained their diet was 4.11 ± 0.87 days whereas in traditional tonsillectomy group it was 6.14 ± 1.14 days. There was no case observed with episode of primary or secondary hemorrhage. We conclude from this study that coblation tonsillectomy takes less operating time with less blood loss, also associated with less post-operative pain, less time taken to achieve normal diet and activities.

Abstract
Purpose The conventional alveoloplasty approach which uses manual equipment results in more resorption of the underlying alveolar ridge that makes denture prosthesis unstable. The goal of this study was to compare results of piezosurgery alveoloplasty to those of conventional alveoloplasty. Materials and Methods This was an in-vivo comparative study consisting of ten edentulous individuals who needed alveoloplasty due to bilateral bony projection. On one side, a conventional alveoloplasty was performed with a bone rongeur and bone file, whereas the contralateral side was treated with a piezosurgery unit. The clinical parameters were analyzed using SPSS version 21 software including operating time, postoperative pain evaluation on day 3 and a healing on day 7. Results There was a statistically significant difference between the two groups in terms of outcome variables such as operating time, pain and healing. The Conventional group has a lower mean of operating time, a higher mean rank of VAS and a lower mean rank of healing index compared to the piezosurgery group. Conclusion Piezosurgery alveoloplasty not only lowers postoperative patient discomfort but also preserves alveolar bone integrity by not disrupting soft and hard tissue architecture thus allowing faster tissue healing and easier prosthesis replacement in the future.

Abstract
In organic table egg production, saponified extracts of carotenoids are not allowed to intensify egg yolk colour. Therefore, we investigated the suitability of organically produced marigold flower meal (Tagetes erectus, TE) and spinach (Spinacia oleracea, SO) as carotenoid sources (mixture of 25% TE and 75% SO) to reach values of 9-10 'Roche Yolk Colour Fan' units (RYCF units). Feeding a completely unsupplemented control diet resulted in a yolk colour of 4.7 RYCF units, a total supply of 11.1 g/kg, 14.6 g/kg and 17.5 g/kg of TE and SO as stand-alone carotenoid sources induced a significant increase to 8.0, 8.2 and 8.9 RYCF units. Under 'winter-feeding conditions', i.e. minimal carotenoid supply in the diet, 17.5 g/kg TE and SO resulted in 9.3 ± 0.7 RYCF units. It can be concluded that supplementing TE and SO is suitable to improve the yolk colour in organically produced table eggs.

Abstract
BACKGROUND AND AIM Classical autoimmune hepatitis (AIH) is characterized by the presence of conventional autoantibodies (anti-smooth muscle, antinuclear and anti-liver-kidney-microsomal antibodies). The absence of such autoantibodies in some patients does not preclude AIH diagnosis or the need for its treatment. This group of patients was termed seronegative AIH. Whether non-conventional autoantibodies can identify this group of patients is still elusive. We aimed to study the prevalence of seronegativity of conventional autoantibodies and the occurrence of non-conventional autoantibodies in children with AIH. METHODS In this study, 55 children with AIH were investigated for non-conventional autoantibodies (anti-neutrophil cytoplasmic antibodies, antibodies to soluble liver antigen, anti-tissue transglutaminase and antiplatelet antibodies). All the patients received immunosuppressive therapy and were assessed for treatment response. RESULTS Of the patients 44 had classical AIH (type 1, 70.09%, type 2, 9.09%) and 20% were seronegative. The four studied non-conventional autoantibodies occurred in four patients, one for each. All non-conventional autoantibodies were exclusively associated with type 1 AIH. The clinical profile, ultrasonographic findings, liver biochemistry and histopathological findings were comparable in the classical and seronegative AIH. The majority of patients with classical (72.7%) and seronegative (54.5%) AIH were treatment responders. CONCLUSION Seronegative AIH represents a substantial percentage of pediatric patients diagnosed with AIH. They were even negative for non-conventional autoantibodies. Furthermore, apart from autoantibodies, seronegative AIH is almost indistinguishable from the classical AIH and the majority of patients were treatment responders. This favorable response to immunosuppression deserves sustainable efforts for considering such a diagnosis and start therapy to halt disease progression is worthwhile.

PURPOSE Correct positioning and alignment of the prosthesis is a very important factor for durability of prosthesis and implant survival which is improved with the use of technology in total knee arthroplasty. However, the long-term functional outcomes and survivorship are unclear. For this study, it was hypothesized that mechanical axis alignment of lower limb, post-operative joint line restoration, femoral and tibial component alignment is more accurate with the new handheld semi-active robotic-assisted TKA. METHOD From April-2019 to March-2020, 60 patients with unilateral knee osteoarthritis who underwent total knee arthroplasties were included in this prospective randomised controlled study. Computer generated randomization was used. Study included 48 female patients and 12 male patients. Pre-operative and post-operative radiographic measurements were done and compared between the two groups. RESULTS There was a significant difference between two groups with respect to mechanical axis deviation, joint line deviation and coronal alignment of femoral and tibial prosthesis. Mechanical axis deviation > 3° was seen in eight cases (28.5%) in C-TKA group compared to one case (3.1%) in RA-TKA (p 0.019). Joint line deviation of 3.5 mm was noted in C-TKA group as compared to 0.9 mm in RA-TKA group (p < 0.001) which was statistically significant. However, whether this difference of 2.6 mm of joint line elevation between C-TKA and RA-TKA leads to any difference in clinical outcome in terms of knee kinematics and knee flexion needs to be investigated with further studies. Clinically restoring normal joint line is important for improved knee function after primary TKA. No significant difference was noted in femoral component rotation on post-operative computed tomography (CT) scan. CONCLUSION The novel imageless, handheld semi-autonomous robotic system for TKA is highly accurate with respect to component positioning in coronal plane and mechanical alignment as compared to conventional TKA. Joint line is elevated in conventional TKA but is accurately restored using the robotic-assisted TKA which may lead to better patellofemoral kinematics. LEVEL OF EVIDENCE I.

Abstract
First known comparison of antimicrobial resistance traits in E. coli strains from new zealand farms practicing organic and conventional husbandry. Potential extended spectrum β-lactamase producing strains isolated from dairy farm environments. Organic dairy farms tended to harbour fewer resistant isolates than those recovered from conventionally farmed counterparts. Evidence for anthroponotic transmission of resistant strains of human origin to farm environments. Implications for the spread of antimicrobial resistance traits from farm environments discussed.
The prevalence and spread of antimicrobial resistance (AMR) as a result of the persistent use and/or abuse of antimicrobials is a key health problem for health authorities and governments worldwide. A study of contrasting farming systems such as organic versus conventional dairy farming may help to authenticate some factors that may contribute to the prevalence and spread of AMR in their soils. A case study was conducted in organic and conventional dairy farms in the South Canterbury region of New Zealand. A total of 814 dairy farm soil E. coli (DfSEC) isolates recovered over two years were studied. Isolates were recovered from each of two farms practicing organic, and another two practicing conventional husbandries. The E. coli isolates were examined for their antimicrobial resistance (AMR) against cefoxitin, cefpodoxime, chloramphenicol, ciprofloxacin, gentamicin, meropenem, nalidixic acid, and tetracycline. Phylogenetic relationships were assessed using an established multiplex PCR method. The AMR results indicated 3.7% of the DfSEC isolates were resistant to at least one of the eight selected antimicrobials. Of the resistant isolates, DfSEC from the organic dairy farms showed a lower prevalence of resistance to the antimicrobials tested, compared to their counterparts from the conventional farms. Phylogenetic analysis placed the majority (73.7%) of isolates recovered in group B1, itself dominated by isolates of bovine origin. The tendency for higher rates of resistance among strains from conventional farming may be important for future decision-making around farming practices Current husbandry practices may contribute to the prevalence and spread of AMR in the industry.

Abstract
Objective Glottic cancer has an excellent probability of cure. The early glottic cancer is usually treated by radiotherapy with different fractionation schedules. The aim of this study was to compare conventional versus hypofractionated radiotherapy with respect to overall survival and disease-free survival. Materials and Methods A total of fifty patients with T1-2N0M0 glottic cancer with no previous treatment history were prospectively randomized into two arms. In Arm A (Study), patients received a total of 55 Gy in 20# at 2.75 Gy/#, 5 days a week. In Arm B (Control), patients received a total of 66 Gy in 33# at 2 Gy/#, 5 days a week. Disease response was evaluated by the WHO criteria at the end of treatment, then at 1, 2, and 3 months to complete their 6-month follow-up. Overall survival and disease-free survival were evaluated at 1, 2, and 3 years. Results Overall, 100% of patients in the study arm and 96% of patients in the control arm had complete response after 6 months. Overall survival rates at 1, 2, and 3 years were 96%, 96%, and 88%, respectively, in the study arm, while in the control arm, these values were 92%, 84%, and 80%, respectively, and the difference was not statistically significant (P > 0.05). Disease-free survival at 3 years was 88% in the study arm and 80% in the control arm. Conclusion The study suggests that hypofractionated regimen may be better in local control and symptomatic relief with the added advantage of shorter treatment time, which offers better patient compliance and advantageous in busy setups where there is heavy patient load.

Abstract
Background and Aims: Osteoarthritis is a progressive degenerative joint disease that affects the joint cartilage and surrounding tissues. It has been determined that osteoarthritis-induced knee pain is the most common cause of physical disability in the elderly. Material and Methods: In this study, the genicular nerve RF treatments of patients with osteoarthritic knee pain conducted at the Sakarya University Training and Research Hospital in the algology clinic of the Anaesthesiology and Reanimation Department between January 2016 and December 2016 were retrospectively examined. The preoperative and postoperative 2nd, 6th, and 12th week visual analog scale (VAS) and Turkish validated Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores were recorded. In addition, any complications after the treatment and side effects (bleeding, neurological damage, infection, etc.) were recorded in the file. Results: When the data of the patients were evaluated statistically, the preoperative VAS and WOMAC scores were found significantly decreased compared with the postoperative 2nd week, 6th week, and 12th week scores in patients who applied both conventional radiofrequency (RF) and cooled RF. However, there was no statistically significant difference between the two techniques. Conclusion: We found that both cooled and conventional RF techniques in genicular nerve ablation are similarly effective in reducing pain in patients with osteoarthritis-induced knee pain and improving patients’ physical functions. The complication rates are very low and there was no superiority to each other.

Abstract
There is public and scientific concern about air, soil and water contamination and possible adverse environmental and human health effects as a result of hydraulic fracturing activities. The use of greener chemicals in fracturing fluid aims to mitigate these effects. This study compares fracturing fluids marketed as either 'conventional' or 'green', as assessed by their chemical composition and their toxicity in bioassays. Chemical composition was analysed via non-target screening using liquid chromatography - high resolution mass spectrometry, while toxicity was evaluated by the Ames fluctuation test to assess mutagenicity and CALUX reporter gene assays to determine specific toxicity. Overall, the results do not indicate that the 'green' fluids are less harmful than the 'conventional' ones. First, there is no clear indication that the selected green fluids contain chemicals present at lower concentrations than the selected conventional fluids. Second, the predicted environmental fate of the identified compounds does not seem to be clearly distinct between the 'green' and 'conventional' fluids, based on the available data for the top five chemicals based on signal intensity that were tentatively identified. Furthermore, Ames fluctuation test results indicate that the green fluids have a similar genotoxic potential than the conventional fluids. Results of the CALUX reporter gene assays add to the evidence that there is no clear difference between the green and conventional fluids. These results do not support the claim that currently available and tested green-labeled fracturing fluids are environmentally more friendly alternatives to conventional fracturing fluids.

Abstract
Chondrosarcomas are heterogeneous matrix-producing cartilaginous neoplasms with variable clinical behavior. Subtypes include conventional (75%), dedifferentiated (10%), clear cell (2%), mesenchymal (2%), and periosteal chondrosarcoma (<1%). Tumor location and primary vs secondary also play a role. In conventional chondrosarcoma, histologic grading (I, II, and III) remains the gold standard for predicting recurrence and metastases. Due to the locally aggressive but overall nonmetastatic behavior, grade I chondrosarcomas (primary and secondary) of long and short tubular bones have been reclassified as atypical cartilaginous tumor. In this review, the pathologic features of malignant cartilage tumors are discussed with updates on recent genetic findings.

Abstract
BACKGROUND & AIMS Conventional endoscopic mucosal resection (CEMR) with submucosal injection is the current standard for the resection of large, nonmalignant colorectal polyps. We investigated whether underwater endoscopic mucosal resection (UEMR) is superior to CEMR for large (20-40mm) sessile or flat colorectal polyps. METHODS In this prospective randomized controlled study, patients with sessile or flat colorectal polyps between 20 and 40 mm in size were randomly assigned to UEMR or CEMR. The primary outcome was the recurrence rate after 6 months. Secondary outcomes included en bloc and R0 resection rates, number of resected pieces, procedure time, and adverse events. RESULTS En bloc resection rates were 33.3% in the UEMR group and 18.4% in the CEMR group (P = .045); R0 resection rates were 32.1% and 15.8% for UEMR vs CEMR, respectively (P = .025). UEMR was performed with significantly fewer pieces compared to CEMR (2 pieces: 45.5% UEMR vs 17.7% CEMR; P = .001). The overall recurrence rate did not differ between both groups (P = .253); however, subgroup analysis showed a significant difference in favor of UEMR for lesions of >30 mm to ≤40 mm in size (P = .031). The resection time was significantly shorter in the UEMR group (8 vs 14 minutes; P < .001). Adverse events did not differ between both groups (P = .611). CONCLUSIONS UEMR is superior to CEMR regarding en bloc resection, R0 resection, and procedure time for large colorectal lesions and shows significantly lower recurrence rates for lesions >30 mm to ≤40 mm in size. UEMR should be considered for the endoscopic resection of large colorectal polyps.

Abstract
Introduction breast lump is the commonest presentation for both benign and maligant breast conditions. Both ultrasound guided and conventional fine needle aspiration cytology (FNAC) have been used for diagnosing of breast malignancy among patients with palpable breast lumps. This study compared diagnostic utility of ultrasound guided versus conventional FNAC in diagnosing breast malignancies among patients with palpable breast lumps at Bugando Medical Centre. Methods this was a hospital based cross sectional study with a follow up component that combined both retrospective data (from January 2017 to June 2018) and prospective data (from July 2018 to June 2019). Results during the study, total of 354 patients (male; female = 1: 32) were enrolled in the study. A total of 134 (37.9%) patients had malignant lesions while 220 (62.1%) of patients had benign lesions confirmed on histology. The diagnostic utility (sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy) for conventional FNAC was 86.7%, 95.7%, 93.5%, 91.1% and 92.0% with an 8% error margin versus ultrasound guided FNAC all were 100% with a 0% error margin respectively. Conclusion both ultrasound guided and conventional FNAC show almost perfect agreement with histology. However, ultrasound guided FNAC has a higher diagnostic utility relative to conventional FNAC in diagnosing breast malignancies.

Abstract
PURPOSE Complete mesocolic excision (CME) has been proposed for better local control of colon cancer and to improve cancer-specific survival (CSS). However, CME may be associated with increased morbidity from bleeding during central vascular ligation. This study aimed to investigate the outcome of conventional right hemicolectomy, a traditional anatomical dissection along anatomical planes with radical excision of the central lymph nodes at the level of the origin of colic artery but without exposure of superior mesenteric vein and artery (SMV/SMA). METHOD This was a retrospective review of a cohort of all elective right hemicolectomies performed at a specialist tertiary unit during a five-year period (2011-2015). RESULTS Five-hundred-nineteen patients (271 female, a median age of 73.0 years (interquartile range (IQR) 65.0-80.0)) were included (Stage I disease: 2.7%, stage II: 53.2%, stage III: 33.3%, stage IV: 10.8%). At the latest follow-up (a median 47 months (IQR 29-67)), local recurrence occurred in 34 patients (6.6%). Three-year overall survival was 74.4% and 3-year CSS was 85.9%. Subgroup analysis for stage I-III showed local recurrence in 6.0%, sole distant recurrence in 7.6% while 19 patients (4.1%) suffered concomitant local and distant recurrence. The anastomotic leak rate was 1.0% and perioperative bleeding occurred in 1.2%. CONCLUSIONS Oncological outcomes comparable to those of CME can be achieved by conventional surgery but with low rates of bleeding complications and anastomotic leakage. The proposed advantages of CME should be carefully considered and balanced against patients' co-morbidities and potential complications.

Abstract
BACKGROUND Colon cancer is the second leading cause of cancer related deaths worldwide with about 1.2 million new cases identified annually. While considering swift progress in the field of molecular biology, new horizons in the treatment approaches have been materialized in colon cancer with conventional methods being replaced with targeted therapies. METHODS In this review, we focused on the existing conventional therapies utilized for colon cancer by comparing the effectiveness of various standard/conventional therapies with respect to overall survival parameter. Regardless of all the conventional treatments and scientific research, the disease remains to be the one of the major cause of cancer related death and rising as societal burden due to its co morbidities. Thus, we have also discussed briefly in this review, all the possible biotechnological next-generation therapeutics including nucleic acid medicines, CRISPR-Cas9 technology, adoptive cell therapy, cancer stem cells and therapy, gut microbiome, and personalized medicines, which might be promising after effective clinical trials. RESULTS From our study, we suggest that the use of neoadjuvant chemoradiotherapy in resected patients was found to be safe and effective therapy in treating colon cancer and thereby improving overall survival in patients. From considering the total estimate of our meta-analysis plot, we state that the existing therapies are not much satisfying to improve the overall survival and more research has to be carried out in this field to find an effective therapy to treat colon cancer. CONCLUSIONS As existing therapies are not much satisfying and are unable to improve the overall survival, we brought together a diversity of possible approaches focusing on biotechnological nextgeneration therapeutics to treat colon cancer. Hence, various multi-disciplinary choices are mandatory in order to provide patients with distended access to tailored treatments.

Abstract
OBJECTIVES Previous meta-analysis including nonrandomized studies showed marginal benefit of underwater endoscopic mucosal resection(U-EMR) compared to conventional EMR(C-EMR) in terms of polypectomy outcomes. We evaluated U-EMR compared to C-EMR in the treatment of colorectal polyps with respect to effectiveness and safety by analyzing only randomized controlled trials(RCTs). MATERIAL AND METHODS PubMed and Cochrane Library databases were searched for RCTs published until 11/2020, evaluating U-EMR vs. C-EMR regarding en bloc resection, post-endoscopic resection adenoma recurrence, complete resection, adverse events rates and difference in resection time. Abstracts from Digestive Disease Week, United European Gastroenterology Week and ESGE Days meetings were also searched. Effect size on outcomes is presented as risk ratio(RR; 95% confidence interval[CI]) or mean difference(MD; 95%CI). The I2 test was used for quantifying heterogeneity, while Grading of Recommendations Assessment, Development and Evaluation(GRADE) was used to assess strength of evidence. RESULTS Six RCTs analyzing outcomes from 1157 colorectal polypectomies(U-EMR589;C-EMR,568) were included. U-EMR associated with significant higher rate of en bloc resection compared to C-EMR [RR(95%CI):1.26(1.01-1.58); Chi² for heterogeneity=30.43, P<0.0001; I²=84%, GRADE: Very low]. This effect was more prominent regarding resection of polyps sized ≥20 mm compared to polyps <20 mm [RR(95%CI):1.64(1.22-2.20) vs. 1.10(0.98-1.23)]. Post-resection recurrence [RR(95%CI):0.52(0.28-0.94);GRADE:Low] was lower significantly in U-EMR group. In contrast, no significant difference was detected between U-EMR and C-EMR regarding complete resection [RR(95%CI): 1.06(0.91-1.24) GRADE:Very low] and adverse events occurrence[RR(95%CI):1.00 (0.72-1.39); GRADE:Low]. CONCLUSION Meta-analysis of RCTs supports that U-EMR resection achieves higher rate of en bloc resection compared to conventional EMR. This effect is driven when resecting large(≥20 mm) polyps.

Abstract
BACKGROUND Assessment is a necessary part of training postgraduate medical residents. The implementation of methods located at the "shows how" level of Miller's pyramid is believed to be more effective than previous conventional tools. In this study, we quantitatively compared electronic and conventional methods in assessing ophthalmology residents. METHODS In this retrospective study, eight different conventional methods of assessment including residents' attendance, logbook, scholarship and research skills, journal club, outpatient department participation, Multiple Choice Question (MCQ), Objective Structured Clinical Examination (OSCE), and professionalism/360-degree (as one complex) were used to assess 24 ophthalmology residents of all grades. Electronic media consisting of an online Patient Management Problem (e-PMP), and modified electronic OSCE (me-OSCE) tests performed 3 weeks later were also evaluated for each of the 24 residents. Quantitative analysis was then performed comparing the conventional and electronic assessment tools, statistically assessing the correlation between the two approaches. RESULTS Twenty-four ophthalmology residents of different grades were included in this study. In the electronic assessment, average e-PMP scores (48.01 ± 12.40) were much lower than me-OSCE (65.34 ± 17.11). The total average electronic score was 56.67 ± 11.28, while the total average conventional score was 80.74 ± 5.99. Female and male residents' average scores in the electronic and conventional method were (59.15 ± 12.32 versus 83.01 ± 4.95) and (55.19 ± 10.77 versus 79.38 ± 6.29), respectively. The correlation between modified electronic OSCE and all conventional methods was not statistically significant (P-value >0.05). Correlation between e-PMP and six conventional methods, consisting of professionalism/360-degree assessment tool, logbook, research skills, Multiple Choice Questions, Outpatient department participation, and Journal club active participation was statistically significant (P-value < 0.05). The overall correlation between conventional and electronic methods was significant (P-value = 0.017). CONCLUSION In this study, we conclude that electronic PMP can be used alongside all conventional tools, and overall, e-assessment methods could replace currently used conventional methods. Combined electronic PMP and me-OSCE can be used as a replacement for currently used gold-standard assessment methods, including 360-degree assessment.

Abstract
The efficacy of primary sutureless repair for supracardiac total anomalous pulmonary venous connection (TAPVC) needs to be confirmed. This study aimed to compare the long-term outcomes between the conventional surgery and the sutureless technique with a modified approach in superior TAPVC. Between January 2008 and December 2018, 173 patients with supracardiac TAPVC underwent surgery either with the conventional procedure (n = 130) or the sutureless repair (n = 43). Multivariate analysis and competing-risk analysis were used to identify risk factors for early death and postoperative pulmonary venous obstruction (PVO), respectively. Among 173 patients who underwent repair of supracardiac TAPVC, 46 (28%) had preoperative PVO, and 22 (12.7%) had postoperative PVO. The sutureless group had a lower postoperative PVO rate compared with the conventional group (p = 0.027). The risk factors for death were age ≤ 28 days [odds ratio (OR), 11.56; 95% confidence interval (CI) 1.33-100.47, p = 0.015], weight ≤ 3 kg (OR 9.57; 95% CI 1.58-58.09, p = 0.009), emergency operation (OR 19.24; 95% CI 3.18-116.35, p = 0.002), cardiopulmonary bypass time (OR 2.16; 95% CI 1.36-3.43, p = 0.003), cross-clamp time (OR 1.73; 95% CI 1.20-2.50, p = 0.022), and duration of ventilation (OR 1.11; 95% CI 1.02-1.21, p = 0.027). Age ≤ 28 days [Hazard Ratio (HR) 1.92; 95% CI 1.92-11.02, p < 0.001] and preoperative PVO (HR 41.70; 95% CI 8.15-213.5, p < 0.001) were associated with postoperative PVO. The sutureless repair is a reliable technique for supracardiac TAPVC. Age ≤ 28 days is associated with 30-day mortality and postoperative PVO.

Abstract
Toxoplasma gondii infection can result in toxoplasmosis and potential psychological effects. Research commonly focuses on infection through contact with cat fecal matter or consumption of contaminated meat. However, T. gondii oocysts can persist in the environment for years and may be present in soils and on soil-grown produce. Rates of oocyst DNA recovery from produce were high, with 18% of vegetable samples testing positive for T. gondii via PCR test and melt curve analysis. Radishes had significantly higher oocyst counts than arugula, collard greens, kale, lettuce, and spinach. There were no significant differences in oocyst detection rates between samples taken from organic farmer's markets and conventional grocery stores. This study demonstrates that these oocysts can transfer to produce grown both conventionally and using organic techniques.

Abstract
Background Recent developments in robotic technology have brought significant changes in robotic video-assisted thoracoscopic surgery (r-VATS) worldwide, particularly including the treatment in the thorax for the mediastinal, esophagus, and pulmonary lesions. Currently, there are only a few reports describing the procedural experience and outcomes with r-VATS. The objective of this study is to provide our initial experience using r-VATS at a single center, with specific attention to safety, efficacy, and procedural details. Methods We retrospectively reviewed patients who underwent a newly modified r-VATS procedure for various surgical operations at the thoracic department of our hospital, from July 2018 to January 2020. Multiport trocars were placed in the classic triangular arrangement as in conventional VATS (c-VATS) but with modifications based on the type of surgery. The peri- and postoperative outcomes such as duration of surgery, complications, and duration of hospital stay for these patients were reported. Results Overall, 142 patients underwent r-VATS for lobectomy (66), wedge resection (15), thymectomy (22), mediastinal tumor resection (30), pneumonectomy (4), transthoracic esophagectomy (1), esophageal tumor resection or esophageal diverticulum repair (2), diaphragm plication (1), and mediastinal tumor resection plus thymectomy (1). For the entire cohort, the median operative time was 110 min, and the median length of hospital stay was 5 days. Conversion to open thoracic surgery was reported only in a total of 3 (2.1%) patients of pneumonectomy (1.4%) and mediastinal tumor resection (0.70%). All our patients were managed successfully with no postoperative complications and mortality. Conclusion Our method of r-VATS was found to be safe and effective and may be applied to different surgical operations. Adequate and proper training of thoracic surgeons is immediately needed for the transition from c-VATS to r-VATS. The utility and advantages of triangular trocar configuration for r-VATS require further refinement and research before it can be routinely adopted in clinical practice. Trial registration Retrospectively registered.

Abstract
OBJECTIVE In female cancer patients anticipating chemotherapy or radiation, oocyte retrieval for fertility should be performed as efficiently as possible to avoid postponing cancer treatments. Our objective was to compare clinical outcomes among female cancer patients who underwent a conventional early follicular phase-start ovarian stimulation cycle and those who underwent a random-start ovarian stimulation cycle. EVIDENCE REVIEW A systematic review of the literature was performed in accordance with PRISMA guidelines. Medline, Embase.com, Scopus, Cochrane Library, and Clinicaltrials.gov databases were searched to identify all original research published in English through July 2020 on the topic of female cancer patients undergoing ovarian stimulation with a random or conventional start. Studies lacking a comparison group or including women who had already undergone chemotherapy at the time of ovarian stimulation were excluded. The primary author assessed all identified article titles and abstracts, and two independent reviewers assessed full-text articles and extracted data. A meta-analysis with a random-effects model was used to calculate weighted mean differences (WMDs) for outcomes of interest. The primary outcome was the number of mature (meiosis II) oocytes retrieved. Secondary outcomes included duration of stimulation, total dose of gonadotropins, total number of oocytes retrieved, fertilization rate, and number of embryos or zygotes cryopreserved. RESULTS A total of 446 articles were screened, and 9 full-text articles (all retrospective cohort or prospective observational) were included for review. Additionally, pooled primary retrospective data from two institutions were included. In total, data from 10 studies including 1653 women were reviewed. Five studies reported the number of embryos cryopreserved, and four reported fertilization rates. Random-start cycles were slightly longer (WMD 0.57 days, 95 % confidence interval [CI] 0.0-1.14 days) and used more total gonadotropins (WMD 248.8 international units, 95 % CI 57.24-440.40) than conventional-start cycles. However, there were no differences in number of mature oocytes retrieved (WMD 0.41 oocytes, 95 % CI -0.84-1.66), number of total oocytes retrieved (WMD 0.90 oocytes, 95 % CI -0.21-2.02), fertilization rates (WMD -0.12, 95 % CI -1.22-0.98), or number of embryos cryopreserved (WMD 0.12 embryos, 95 %CI -0.98-1.22) between random-start and conventional-start cycles. All outcomes except for the parameter "total oocytes retrieved" yielded an I2 of over 50 %, indicating substantial heterogeneity between studies. CONCLUSION(S) Although random-start cycles may entail a longer duration of stimulation and use more total gonadotropins than conventional-start cycles, the absolute differences are small and likely do not significantly affect treatment costs. The similar numbers of mature oocytes retrieved, fertilization rates, and number of embryos cryopreserved in the two start-types suggest that they do not differ in any clinically important ways. Given that random-start cycles can be initiated quickly, they may help facilitate fertility preservation for cancer patients.

Abstract
AIMS To compare changes in gait kinematics and walking speed 24 months after conventional (C-MLS) and minimally invasive (MI-MLS) multilevel surgery for children with diplegic cerebral palsy (CP). METHODS A retrospective analysis of 19 children following C-MLS, with mean age at surgery of 12 years five months (seven years ten months to 15 years 11 months), and 36 children following MI-MLS, with mean age at surgery of ten years seven months (seven years one month to 14 years ten months), was performed. The Gait Profile Score (GPS) and walking speed were collected preoperatively and six, 12 and 24 months postoperatively. Type and frequency of procedures as part of MLS, surgical adverse events, and subsequent surgery were recorded. RESULTS In both groups, GPS improved from the preoperative gait analysis to the six-month assessment with maintenance at 12 and 24 months postoperatively. While reduced at six months in both groups, walking speed returned to preoperative speed by 12 months. The overall pattern of change in GPS and walking speed was similar over time following C-MLS and MI-MLS. There was a median of ten procedures per child as part of both C-MLS (interquartile range (IQR) 8.0 to 11.0) and MI-MLS (IQR 7.8 to 11.0). Surgical adverse events occurred in seven (37%) and 13 (36%) children, with four (21%) and 13 (36%) patients requiring subsequent surgery following C-MLS and MI-MLS, respectively. CONCLUSION This study indicates similar improvements in gait kinematics and walking speed 24 months after C-MLS and MI-MLS for children with diplegic CP.

Abstract
Context Stress hyperglycemia in critically ill patients has been a matter of debate for years without any conclusive answer till date regarding glucose management and treatment thresholds. Aims We planned a study with an aim to compare the efficacy of intensive versus conventional insulin therapy in reducing the mortality and morbidity in critically ill patients. The primary objective was to compare mortality between the two groups. The secondary objective was to find out if intensive insulin therapy is better than conventional insulin therapy in terms of various outcomes such as infections and need for inotropes and transfusion requirements. Settings and Design It was a prospective randomized controlled study. The study population included 100 patients who received mechanical ventilation and admitted to the intensive care department of a tertiary care institute. Subjects and Methods Patients were randomly assigned to two groups: intensive insulin therapy (IIT) and conventional insulin therapy (CIT) to receive either intensive or conventional insulin therapy. Insulin infusion was started only when blood glucose levels exceeded 200 mg%. Blood glucose levels were maintained between 80 and 110 mg% in the IIG and between 180 and 200 mg% in the CIG. Statistical Analysis Used The data collected were analyzed separately for both the groups using Student's t-test and Chi-square test. Results The two groups were comparable in terms of baseline demographic data including age, sex, preadmission diabetic status, and HbA1c at the time of admission. The two groups were not comparable in terms of Acute Physiology and Chronic Health Evaluation-II scores, and the difference between them was statistically significant with higher scores in the conventional group. The primary outcome, that is, mortality, was higher in the CIG with 29 patients (58%) versus 3 (6%) in the IIG (P = 0.02). The secondary outcomes were the measures of morbidity including infections, need for inotropic support, and need for blood transfusions, and these were significantly higher in the conventional group (P < 0.05). Conclusions We conclude that tight glycemic control significantly lowers mortality and morbidity in critically ill patients, both surgical and medical. These benefits appear with the maintenance of tight blood glucose control of 80-110 mg.dL - 1 and not due to administration of insulin.

Abstract
PURPOSE Accurate implant position in total knee arthroplasty (TKA) can potentially lead to better long-term functional outcomes and implant survival. Recent studies on whether better clinical results could be obtained from computer-navigated or conventional TKA were inconclusive. In addition, recent reviews only included short-term follow-up studies without performing quantitative mid- to long-term follow-up analysis. Thus, the purpose of the present study was to perform a meta-analysis comparing mid- to long-term clinical outcomes (such as knee scoring and functional results) and radiological outcomes (such as normal alignment of the limb axis or component) between computer-navigated TKA and conventional TKA to determine which method of TKA could obtain better clinical and radiological results. METHODS MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, and SCOPUS electronic databases were searched for relevant articles published through August 2018 that compared outcomes of computer-navigated TKA and conventional TKA. Data search, extraction, analysis, and quality assessment were performed according to the Cochrane Collaboration guidelines. Clinical and radiological outcomes of both techniques were evaluated using various outcome measures. RESULTS Seven randomized controlled trials were included. Based on Knee Society Scores, the Western Ontario and McMaster Universities Osteoarthritis Index, pain, and range of motion, there were no significant differences in clinical outcomes between the two techniques. Based on outliers from the normal axis, outliers of femoral components in the coronal plane, and outliers of tibial components in the coronal plane, radiologic outcomes showed no significant differences between the two techniques either. CONCLUSIONS The present study revealed that there were no significant differences in clinical or radiological outcomes between computer-navigated TKA and conventional TKA. It remains unclear which TKA technique yields better results in terms of mid- to long-term clinical and radiological outcomes. LEVEL OF EVIDENCE I.

Abstract
BACKGROUND We performed this study to compare the safety and feasibility of single-incision laparoscopic cholecystectomy (SILC) with conventional multiple-port laparoscopic cholecystectomy (MPLC). METHODS We searched PubMed, Embase, Web of Science, the Cochrane Controlled Register of Trials (CENTRAL), and ClinicalTrials.gov for randomized controlled trials comparing SILC versus MPLC. We evaluated the pooled outcomes for complications, pain scores, and surgery-related events. This study was performed in accordance with PRISMA guidelines. RESULTS A total of 48 randomized controlled trials involving 2838 patients in the SILC group and 2956 patients in the MPLC group were included in this study. Our results showed that SILC was associated with a higher incidence of incisional hernia (relative risk = 2.51; 95% confidence interval = 1.23-5.12; p = 0.01) and longer operation time (mean difference = 15.27 min; 95% confidence interval = 9.67-20.87; p < 0.00001). There were no significant differences between SILC and MPLC regarding bile duct injury, bile leakage, wound infection, conversion to open surgery, retained common bile duct stones, total complication rate, and estimated blood loss. No difference was observed in postoperative pain assessed by a visual analogue scale between the two groups at four time points (6 h, 8 h, 12 h, and 24 h postprocedure). CONCLUSIONS Based on the current evidence, SILC did not result in better outcomes compared with MPLC and both were equivalent regarding complications. Considering the additional surgical technology and longer operation time, SILC should be chosen with careful consideration.

Abstract
BACKGROUND Total knee arthroplasty (TKA) is a successful procedure in managing end-stage arthritis when non-operative treatments fail. New technologies such as robotic TKA (rTKA) have been developed to improve the accuracy of prosthesis implantation. While short-term cohort studies on rTKA have shown excellent results, the evidence comparing between rTKA and conventional TKA (cTKA) is not yet well established. This meta-analysis aims to compare the efficacy and safety of rTKA versus cTKA in terms of clinical outcomes, radiographic results, complications, peri-operative parameters and costs. METHODS A multi-database search was performed according to PRISMA guidelines. Data from studies comparing between rTKA and cTKA were extracted and analyzed. RESULTS Eighteen studies were included in this review, consisting of 2234 rTKA and 4300 cTKA. Robotic TKA led to a more precise prosthesis implantation with significantly fewer outliers in the mechanical axis (p < 0.001), femoral coronal (p = 0.002) and tibial sagittal (p = 0.01) alignments. Only the Hospital for Special Surgery (HSS) (p < 0.001) score at final follow-up was significantly better in rTKA than cTKA. rTKA also had a lower mean blood loss (p < 0.001) despite a longer mean operation time (p = 0.006). There were no statistically significant difference in terms of other clinical outcome measures, range of motion and complications. CONCLUSION Both rTKA and cTKA are reliable and safe to perform. However, rTKA is capable of achieving superior alignment in several axes, lower mean blood loss and this may lead to marginally better clinical outcomes than cTKA.

Abstract
Elements of whole medical systems (WMSs) are re-emerging in a modern, patient-centered care model that leverages the benefits of evidence-based conventional medical practice with WMSs modalities. Many of these re-emerging modalities had their origins in traditional Chinese medicine, ayurvedic medicine, homeopathy, or naturopathy. To date, research has been conducted predominantly on multimodality treatment of experimental groups, drawing conclusions without a comparative control group or using modalities that are not actually WMSs.
