IntroductionIn remote communities, maternal and child health is often compromised due to limited access to healthcare. Simultaneously, these communities historically rely greatly on traditional birth attendants (TBAs). However, optimal integration of these traditional methods with modern healthcare practices remains a topic of debate. We assessed the effect of maternal and child health training of traditional birth attendants on adverse pregnancy outcomes.MethodsWe conducted a systematic review and meta-analysis to answer the above research question. We independently screened studies using databases like PubMed, Scopus, and CENTRAL, extracted data, and assessed the study quality. Due to fewer original studies in this field, we considered both pre-post and between-group differences to assess the effect of differences. These were synthesised separately, assessed against a p-value function, and subjected to sensitivity analyses.ResultsWe included six interventional studies. Training TBAs reduced the risk of perinatal mortality [0.69, 0.61–0.78] and 7-day neonatal mortality [0.65, 0.53–0.80] but not stillbirth [0.70, 0.39–1.26]. In randomized controlled trials, there is a lower risk of perinatal mortality [0.73, 0.67–0.79] and neonatal mortality [0.70, 0.62–0.80] but not stillbirth [0.81, 0.56–1.18] with trained traditional birth attendants. There are methodological concerns with most existing studies, including domains like allocation concealment.DiscussionThere is some evidence of the benefit of training TBAs, though of a low to very low certainty. Due to fewer studies, inconsistent estimates for different critical outcomes, and concerns with the existing studies, further well-designed studies can give more insights. They can also help optimize the contents of TBA training interventions.ProtocolCRD42023412935 (PROSPERO).

The acetabulum presents as a well-preserved evidence, resistant to taphonomic degradation changes and can thus aid in the age estimation process. A CT-based examination of the acetabulum can further help simplify the process of age estimation by overcoming the time-consuming process of maceration and by doing away with the interference resulting from tissue remnants. The aim of the present study was to evaluate the role of the acetabulum for age estimation in an Indian population through a CT-based examination, using principal component analysis and regression models. CT images of 400 individuals aged 10 years and above were evaluated according to the features defined in the San-Millán-Rissech method of age estimation. Five of the seven morphological features defined by San-Millán-Rissech were appreciable on CT scans, and, to enable further statistical analysis, a cumulative score was computed using these five features. A significant correlation of 0.835 and 0.830 for the right and left acetabulum, respectively, was obtained between computed cumulative scores and chronological age of individuals. No significant sex differences were observed in the scoring of different age-related morphological changes. Regression models were generated using individual features and cumulative scores. Regression models derived using the cumulative score yielded inaccuracy values of 9.67 years for the right acetabulum and 9.15 years for the left acetabulum. Inaccuracy and bias values were computed for each individual feature, as well as for each decade, using mean point ages established within the original study. Amongst the various features, acetabular rim porosity was seen to have the lowest values of inaccuracy (11.50 years) and bias (2.32 years) and activity on outer edge of acetabular fossa the highest (inaccuracy and bias values of 22.36 years and 21.50 years, respectively). Taking into consideration this differential contribution towards age estimation, weighted coefficients and mean point ages for different morphological features were determined using principal component analysis. Subsequently, summary age models were generated from the obtained weighted coefficients and mean age values. Summary age models derived in the present study yield lower estimates of inaccuracy of 7.60 years for the right acetabulum and 7.82 years for the left acetabulum. While regression models derived in the present study allow for age estimation using even a single appreciable feature, summary age models take into account the contribution of each feature and generate more accurate estimates of age. Both statistical computations yield reduced error rates and thus can render greater applicability to the acetabulum in forensic age estimation.

Age estimation constitutes one of the pillars of human identification. The auricular surface of the ilium presents as a durable and robust structure within the human skeletal framework, capable of enabling accurate age estimation in older adults. Amongst different documented auricular age estimation methods, the Buckberry-Chamberlain method offers greater objectivity through its component-based approach. The present study aimed to test the applicability of the Buckberry-Chamberlain method in an Indian population through a CT-based examination of the auricular surface. CT scans of 435 participants undergoing CT examinations following the advice of their treating physicians were scrutinized for different age-related auricular changes. Three of the five morphological features described by Buckberry-Chamberlain could be appreciated on CT scans, and thus further statistical analysis was restricted to these features. Transition analysis coupled with Bayesian inference was undertaken individually for each feature to enable age estimation from individual features, while circumventing age mimicry. A Bayesian analysis of individual features yielded highest accuracy percentages (98.64%) and error rates (12.99 years) with macroporosity. Transverse organization and apical changes yielded accuracy percentages of 91.67% and 94.84%, respectively, with inaccuracy computations of 10.18 years and 11.74 years, respectively. Summary age models, i.e. multivariate age estimation models, derived by taking this differential accuracy and inaccuracy into consideration yielded a reduced inaccuracy value of 8.52 years. While Bayesian analysis undertaken within the present study enables age estimation from individual morphological features, summary age models appropriately weigh all appreciable features to yield more accurate and reliable estimates of age.

Age estimation constitutes an important aspect of forensic research, investigation and human identification. For the purpose of age estimation, various markers within the skeletal framework are employed. Degenerative morphological changes in the skeleton can be used for age estimation in adults. Amongst the various bones, age-progressive changes in the innominate bone are of particular significance in age estimation. Within the pelvis, the acetabulum presents as a durable and well-preserved evidence, characteristic manifestations of which can be employed for age estimation. The present study aimed at a CT-based evaluation of acetabular changes for the purpose of age estimation in an Indian population. CT images of 250 individuals aged 10–88 years were scrutinized according to the features defined in the Calce method of acetabular age estimation. Scores were allotted to the various features and a cumulative score was calculated. No significant bilateral and sex differences were observed. Significant correlation was obtained between the scores for these defined characteristics and the chronological age of individuals. Population-specific regression models were generated for age estimation. The scoring method devised in the present research requires further validation as it represents a new tool for age estimation in medico-legal cases.

An interesting case of unusual unilateral variant of palmaris longus (PL) tendon of forearm was noticed by us. We found two bellies of PL as well as their different insertions. These observations will help in understanding morphological variations of this muscle and its clinical implications. PL is a fusiform muscle in the superficial flexor group of muscles of forearm. It originates from medial epicondyle of humerus by common flexor tendon. We found PL having one origin, i.e., from medial epicondyle from common tendinous origin of flexor muscles and then it divided to form two bellies having two long tendons distally. Understanding of presence or absence or anomalies of PL is not only important for medical professionals but also for evolutionary biologists. Awareness of anatomy and variations of flexor tendons is important for health care practitioners for the correct diagnosis and management of pain, disease, and trauma of forearm and hand.

Introduction Round window approach and cochleostomy approach can have different depth of electrode insertion during cochlear implantation which itself can alter the audiological outcomes in cochlear implant . Objective The current study was conducted to determine the difference in the depth of electrode insertion via cochleostomy and round widow approach when done serially in same temporal bone. Methodology This is a cross-sectional study conducted in the Department of Otorhinolaryngology in conjunction with Department of Anatomy and Department of Diagnostic and Interventional Radiology over a period of 1 year. 12-electrode array insertion was performed via either approach (cochleostomy or round window) in the cadaveric temporal bone. HRCT temporal bone scan of the implanted temporal bone was done and depth of insertion and various cochlear parameters were calculated. Result A total of 12 temporal bones were included for imaging analysis. The mean cochlear duct length was 32.892 mm; the alpha and beta angles were 58.175° and 8.350°, respectively. The mean angular depth of electrode insertion via round window was found to be 325.2° (SD = 150.5842) and via cochleostomy 327.350 (SD = 112.79) degree and the mean linear depth of electrode insertion via round window was found to be 18.80 (SD = 4.4962) mm via cochleostomy 19.650 (SD = 3.8087) mm, which was calculated using OTOPLAN 1.5.0 software. There was a statically significant difference in linear depth of insertion between round window and cochleostomy. Although the angular depth of insertion was higher in CS group, there was no statistically significant difference with round window type of insertion. Conclusion The depth of electrode insertion is one of the parameters that influences the hearing outcome. Linear depth of electrode insertion was found to be more in case of cochleostomy compared to round window approach ( p  = 0.075) and difference in case of angular depth of electrode insertion existed but not significant ( p  = 0.529).

Introduction With increasing dependence on laparoscopic procedures, precise knowledge of external variations of the liver is essential for good surgical and interventional outcomes, preventing imaging misdiagnosis, and curtailing complications. The present study aims to evaluate the gross anatomical variations of the liver. Materials and Methods The 40 adult cadaveric livers of age 60-80 years were removed during the routine dissection for undergraduate medical students and examined for morphological variations in the form of size, shape, and fissures. Results Accessory fissures were observed on the caudate lobe (CL) in 23 (57.5%), on the quadrate lobe (QL) in seven (17.5%), on the right lobe (RL) in 29 (72.5%), and on the left lobe (LL) in 12 (30%) specimens. Netter's Type 2, Type 4, Type 5, Type 6, and Type 7 liver were observed in four (10%), seven (17.5%), one (2.5%), three (7.5%), and three (7.5%) specimens respectively. The most common shapes of the CL and QL were rectangular in 16 (40%) and quadrangular in 10 (25%) specimens respectively. Pons hepatis were seen in three (7.5%) specimens. The mean length (cm) of RL and LL were 17.75 ±3.09 and 16.9±3.69 respectively, whereas the mean transverse diameter (TD) (cm) of RL and LL were 7.98±1.20 and 7.85±1.58 respectively. The mean length and TD (cm) of CL were 5.62±1.67 and 2.48±1.00 respectively. The mean length and TD (cm) of the QL were 6.00±1.51 and 2.81±0.83 respectively. Conclusion Precise knowledge of these variations would be helpful for surgeons in planning and performing surgical procedures and for anatomists.

Introduction Covid 19 epidemic has affected the people making them undergo emergency procedures requiring intubation. A protective box was innovated at our tertiary care centre to safeguard the HCW during intubation and/or extubation and the study was planned to assess its use and safety among the anaesthesiologists. Methods A cross sectional, questionnaire base survey was done among anaesthesiologists in various strata of residency. The intubation box was used on the patient for intubation and extubation. The experience of participants was recorded via a Google Form and one response per participant was restricted. Participants were divided into two groups, Group 1(1stand 2nd year junior residents) and Group 2 (Senior resident and 3rd year junior resident). A valid response, was received from 25 anaesthesiologists who were either performing or assisting the intubation. The residents were evaluated based on the ease of use and safety features of the box. Results There was a significant difference in the time taken to intubate between the two groups (p = 0.048) and it was found that Group 2 with more experience took less time to intubate than Group 1. Also, more respondents in Group 2 found it easier to manoeuvre the hands to handle instruments than Group 1(p = 0.024). Conclusion We recommend that usage of intubation box during intubation or extubation is a non-harmful and necessary compromise that we must make to protect the /safeguard the well-being of Health Care Worker without affecting patient care in our fight with COVID-19.

Variations in the branching pattern of the common, external, and internal carotid arteries can present as arteriovenous malformations, and their basis can be explained embryologically. Our case was a rare variation presenting as a congenital, very gradually increasing bluish painless swelling at the region of the left lobule of the ear arising from an abnormal vessel (from the postauricular artery) which was explored under general anesthesia through a postauricular curved incision. The abnormal vessel and other feeding vessels were ligated and a sclerosing agent injected. Anomalies of pharyngeal arch arteries like our case can be found resulting from the persistence of channels that normally disappear, and prior knowledge of these anomalies is essential before surgeries like mastoidectomy to prevent alarming hemorrhage.
