Published: August 2021

Objective To evaluate the performance of the systematic (SBx) and targeted prostate biopsy (TBx) in detecting prostate cancer (PCa) and significant prostate cancer (csPCa) and including upfront risk stratification with PSA Density (PSAD) in a biopsy naïve cohort of Chinese men. Methods A total of 348 men from two medical centers were available for analyses. All men underwent a mpMRI scan based on an elevated PSA and/or abnormal digital rectal examination (DRE). A total of 150 men received both SBx and TBx prostate biopsy (PIRADS >= 3). In these men the detection ratio was calculated as the PCa and csPCa prevalence of the TBx strategy divided by the prevalence of PCa and csPCa of the SBx + TBx strategy. For PSAD analyses the percentage missed csPCa were plotted against the clinically relevant thresholds of PSAD (range 0.01 – 0.20). Results In the men with PIRADS >= 3, a total of 89 PCa cases (59 being csPCa) were detected. The TBx alone strategy detected 74 of all PCa, leading to a detection ratio of 0.83 (95% CI 0.74-0.90). For csPCa these numbers were 48 of the total 59 csPCa cases, i.e a detection ratio of 0.81 (95% CI 0.69-0.90).With the focus on avoiding missing csPCa diagnoses a cut-off of PSA D 0.10 seemed optimal in this cohort, leading to a reduction of 15% of all referrals, missing 6% of all PCa and 2% of csPCa. A similar cut-off of PSAD holds if also men with PIRADS >= 2 were included. Conclusion In this Chinese cohort of biopsy naïve men a TBx approach can aid in improved detection of csPCa. Omitting SBx would results in missing csPCa cases. An upfront risk stratification step with the use of PSAD is advised although the optimal PSAD cut-off in Asian men most likely differs from the generally advised cut-off of 0.15 ng/ml/ml.

Published: August 2021

Background: Spiritual care has been considered one of the components of rehabilitation. But its study and applicability is considerably lacking amongst the rehabilitation professionals. The purpose of this study was to identify the barriers in addressing spiritual issues of patients and understanding the perceptions of rehabilitation professionals in order to inculcate a bio-psycho-socio-spiritual model of care.Methods: In this cross sectional survey, 35 rehabilitation medical professionals at our institute completed a questionnaire assessing their opinion about religion, and spirituality with its inclusion in clinical practice & medical education. The individual domains were analyzed through descriptive statistics.Results: The findings suggested that most rehabilitation professionals understand the importance of addressing spiritual issues of patients but lack its feasibility in clinical practice due to multiple barriers, mainly due to lack of time, training, knowledge, fear of imposing religious beliefs and failing to differentiate between religion and spirituality.Conclusions: The lacuna in various dimensions imposes restrictions in imparting spiritual care to patients. It may affect the total care and thus quality of life of such patients. This can be addressed by proper training and sensitization of medical professionals during medical education as well as during clinical practice.

Published: August 2021

Background: Schistosomiasis is a chronic, parasitic disease caused by blood flukes (Schistosoma species). It has been for along time a neglected tropical disease in most of the sub-Saharan countries.Methods: A cross sectional descriptive study was conducted between June 2015 to July 2015 at Chaani village in North “A” District. The school children were interviewed to identify activities which expose them frequently to water contact. Study subjects were selected by using stratified random sampling technique. The selected school children were asked to collect urine sample in well-labeled container. The samples were processed in the laboratory by using standard microbiological techniques (syringe filtration then examined by microscopy) and results were recorded, the data was analyzed.Results: Out of 170 School children 62 were infected with Schistosoma haematobium which is the predominant Schistosoma species found in that area. Among the 62, 45 (57.6%) were male and 17 (42.4%) were female. The level of knowledge of respondents on Schistosomiasis transmission is that 70% of school children have high knowledge, 18% have moderate knowledge and 12% have low knowledge. Other parameters were also assessed like bathing habits and knowledge and functions of Schistosomiasis control drug.Conclusions: Males were significantly more affected by the disease than females. Provision of safe water coupled with education of the communities regarding the modes of transmission of the disease and the way to prevent oneself, as well as provision of sanitary facilities, such as latrines may decrease the disease burden.

Seizure in children: How important is EEG & Neuroimaging?
Authors: Agarwalla Sunil Kumar
Published: August 2021

Seizure in children are generally indicating a potentially serious underlying systemic or CNS disorders that require thorough clinical examination, investigation and management. It is therefore important to establish accurate diagnosis of seizure and its etiology to manage such patients appropriately.

We carried out this study to evaluate different etiology of seizures and its correlation with abnormal EEG & abnormal neuroimaging in the age group of 2mo to 14 years. 200 children presented with seizure to our department from January 2019 to November 2020 were enrolled in this prospective hospital-based study. Detailed history, clinical examination, investigation with special emphasis to EEG & neuroimaging was done and different correlation was drawn by using SSPS 18.0 statistical analysis. Among 200 cases, 6 to 10yr. age group constituted maximum (49%) number of cases. Male to female ratio is 1.5:1. GTCS is the predominant pattern of seizure (60%) in all age groups. EEG abnormality is found in 45%, mostly in focal seizure type. Neuroimaging abnormality found in 29%. Maximum cases (30%) had infectious etiology.

Childhood seizure needs detailed history taking and careful examination. Vedio recording shown by parents / caregivers really help towards differentiating seizure from seizure mimics. EEG has a role in specific seizure type; Neuroimaging at times helps in diagnosis.

There are few studies that describe neuroimaging [Computed Tomography (CT) and Magnetic Resonance Imaging (MRI)] and Electroencephalogram (EEG) data in children who present with new-onset seizures. The EEG is recommended as a part of the neurodiagnostic evaluation of the child with an apparent first unprovoked seizure.

To study the mechanism and clinical features of ocular injury and its outcome associated with bungee cord related eye trauma.

A retrospective review of medical records was performed at our tertiary care centre to identify patients presented with bungee cord related eye injury between March 2016 to February 2017. Data collected from medical records were age, sex, mechanism of injury, clinical features, therapeutic intervention, presenting visual acuity, final visual acuity and length of follow up.

Total of thirteen patients with bungee cord related trauma were identified. Ten (77%) patients presented with closed globe injury and 3(23%) presented with open globe injury. All patients were male with mean age group of 30.15±7.38 years. Presenting visual acuity ranges from 6/12 to NPL. Only seven (54%) of patients were having final visual acuity of better than or equal to 6/18 in injured eye. Three patients (23.1%) with open globe injury had final visual acuity of counting fingers or worse. Main mechanism of injury being combination of blunt and high speed projectile injury due to slippage of metal or plastic hook while the cord is stretched.

Trauma with bungee cord is usually affecting working age group male with injury resulting in loss of workable vision to loss of eye hence there is need of appropriate intervention like use of printed warning on package and modification of hook design to decrease the incidence of bungee cord related trauma.

Dengue is an arboviral infection of public health problems in tropical and sub-tropical countries transmitted to humans through the bite of an infected mosquito of the Stegomyia family. It varies in severity, ranging from influenza-like self-limiting illness to life- threatening, which if left untreated, are associated with mortality as high as 20%.

Find out hematological and coagulation profile in dengue infected children aged 1 to 12 years and association of hematological and coagulation profile with dengue severity.

It is an Observational Cross- sectional study done on 100 dengue patients aged 1 to 12 years during the study period from March 2019 –February 2020.

Among 100 dengue fever, 85 (85%) were categorized as dengue fever (DF), 11(11%) DF with warning signs and 4 (4%) were cases of severe dengue (DHF/DSS) according to revised World Health Organisation 2009. The most common age of presentation was above 6 years and females were afflicted more with dengue fever.100% dengue patients presented with fever. Persisting vomiting, pain abdomen, hepatomegaly and hypotension indicate progression towards severe dengue. Raised Hb% and PCV, low to normal values of WBC as well as predominantly decrease in platelet was seen in severe dengue cases however, both ESR and CRP were normal. The Liver function test was deranged SGOT>SGPT in almost all of the dengue patients and it was 3 to 4 times maximally in DFW and SD. PT, APTT prolongation, increased D- dimer and hypofibrinogenemia associated with the severity of dengue fever.

Dengue is a common viral infection that may have serious consequences especially in children. There is clear difference in pattern of change of both haematological and biochemical parameters in non-severe dengue fever and severe dengue fever. Rising trend of Hb%, PCV, decreasing value of platelet count, raised transaminases (SGOT>SGPT), elevated D- dimer, PT and APTT and hypofibrinogenemia can be used as predictor of entry into critical phase

Purpose

A small number of risk prediction model have been previously reported to predict the infertility treatment success. While the studies of the risk prediction model for the patients with low prognosis are limited. This study aimed to construct and validate a nomogram for the prediction of cumulative live birth rate (CLBR) in patients with low prognosis from a single center database in Chinese population.
Methods

Clinical data of 4,395 patients with low prognosis, who received in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) therapy between 2014 and 2018, were retrieved and randomly divided into training (70%) and the external validation (30%) sets. Multivariate analysis with logistic regression model was conducted.
Results

Multivariate analyses showed that maternal age, body mass index (BMI), basal serum follicle-stimulating hormone (FSH) level, type of infertility, male factors, uterine factors, and usable embryos number at day 3 were risk factors for CLBR in patients with low prognosis. The area under the receiver operating characteristic curve (AUC) of the prediction model was 0.769 (95% confident interval (CI): 0.751, 0.787) in training set. The validation set presented good performance with an AUC of 0.749 (95% CI: 0.720, 0.778). In addition, Hosmer-Lemeshow chi-square value was 10.194 (P = 0.252).
Conclusion

We constructed and validated a nomogram for the prediction of CLBR in low prognosis patients with a single center database in Chinese population. The validated nomogram for the prediction of CLBR could be potentially applied in clinic for IVF counselling in patients with low prognosis.

BackgroundThe Bangkok falls study aimed to identify fall-associated factors, including home healthcare hazards, nutritional status, hydration status, sarcopenia, frailty, locomotive syndrome, and health status of urban older adults in a middle-income country.Methods This was a population-based cohort study that enrolled adults who lived in Bangkok, Thailand. Our study recruited older adults aged ≥ 60 years old, able to walk, and expected to live in the community for at least 2 years. The study had three phases included; phase 1: subject identification and terminology clarification. Phase 2: we collected data at community sites on baseline characteristic and fall risk identification. Examinations and laboratory investigations were scheduled for one month later. Phase 3: telephone follow up for falls rate, functional status and death at 3, 6, 12 months.Results A total 1,001(51.84%) people were enrolled for our study. The average age of our study was 69.9 years old (SD, 6.8), and two-thirds were female. Using “Stopping Elderly Accidents, Death and Injuries” (STEADI) screening fall risk, our study found that 37.7% had scores ≥ 4, which means that there is a risk of fall. In addition, the risk of falls increased among older adults aged 75–84 years (49.5%) and older adults aged ≥ 85 years (67.7%) (P-value < 0.001).ConclusionThis study demonstrated the feasibility of conducting a population-based cohort study among urban older adults in a middle-income country using the local community healthcare system. Our study have a tendency to provide data source for fall risk factors and disability in older adults.

Objective: The purpose of this study was to investigate the relationship between the neutrophil-lymphocyte ratio (NLR), platelet distribution width (PDW) and prognostic nutrient index (PNI), and the prognosis of patients with advanced non-small-cell lung cancer (NSCLC) treated with platinum-based chemotherapy.Methods: A total of 428 patients with advanced NSCLC treated with platinum-based chemotherapy between January 2015 and June 2019 were retrospectively analyzed. The patients were randomly divided into training set (n=300) and test set (n=128) in a ratio of 7:3, respectively. Clinical data and peripheral blood test results were collected within one week prior to the initiation of treatment to calculate PDW, NLR, and PNI. Receiver operating characteristic (ROC) curves were used to determine the optimal cut-off values of PLR, PDW, and PNI. Kaplan-Meier method and Cox regression analysis were used to evaluate the prognostic factors of advanced NSCLC treated with platinum-based chemotherapy. A Nomogram model was established for predicting the prognosis in advanced NSCLC treated with platinum-based chemotherapy. The test set was used for external validation of the prognostic model.Results: There was no significant difference in the proportion of clinical features between the training set and the test set (P＞0.05). The ROC curve analysis determined the optimal cut-off values of PLR, PDW, and PNI to be 3.07, 16.81, and 52.025, respectively. Univariate and multivariate analyses indicated that tumor type (P=0.038), tumor differentiation (P=0.014), NLR (P=0.001), PDW (P<0.001), and PNI (P=0.009) were independent prognostic factors for PFS in patients with advanced NSCLC patients treated with platinum-based chemotherapy. Tumor type (P=0.002), tumor differentiation (P=0.038), EGFR status (P=0.002), NLR (P=0.010), PDW (P=0.001), and PNI (P=0.002) were independent prognostic factors for overall survival (OS) in advanced NSCLC patients treated with platinum-based chemotherapy. The established nomogram was validated internally and externally. The results showed a good agreement between the predicted value and the actual value of the calibration curve.Conclusion: NLR, PDW, PNI, tumor type, and tumor differentiation are independent prognostic factors for PFS in advanced NSCLC patients treated with platinum-based chemotherapy. NLR, PDW, PNI, tumor type, tumor differentiation, and EGFR status are independent prognostic factors for OS in advanced NSCLC patients treated with platinum-based chemotherapy. The established model has an application value in predicting the prognosis of advanced NSCLC patients treated with platinum-based chemotherapy.

Introduction: Magnesium is a metal used in the composition of titanium alloys and imparts porosity. Due to its osteoconductive, biocompatible and biodegradable characteristics, its application in the development of biomedical materials has become attractive.Objective: This study aimed to evaluate the influence of magnesium present in porous Ti-Nb-Sn alloys, which have a low elastic modulus in adhesive, osteogenic properties and the amount of reactive intracellular oxygen species released in mesenchymal stem cells derived from bone marrow equine bone (eBMMSCs).Methods: Mechanical properties of the alloy, such as hardness, compressive strength and elastic modulus, were analyzed, as well as surface morphological characteristics through scanning electron microscopy. The evaluation of magnesium ion release was performed by atomic force spectroscopy. The biological characteristics of the alloy, when in contact with the alloy surface and with the culture medium conditioned with the alloy, were studied by SEM and optical microscopy. Confirmation of osteogenic differentiation by alizarin red and detection of ROS using a Muse® Oxidative Stress Kit based on dihydroetide (DHE).Results and discussion: The alloy showed an elastic modulus close to cortical bone values. The hardness was close to commercial Ti grade 2, and the compressive strength was greater than the value of cortical bone. The eBMMSCs adhered to the surface of the alloy during the experimental time. Osteogenic differentiation was observed with the treatment of eBMMMSCs with conditioned medium. The eBMMSCs treated with conditioned medium decreased ROS production, indicating a possible antioxidant defense potential of magnesium release.
