BACKGROUND
Tuberculosis (TB) remains a major cause of morbidity and death worldwide, with a significant impact on children, especially those under the age of 5 years. The complex diagnosis of pediatric TB, compounded by limited access to more accurate diagnostic tests, underscores the need for improved tools to enhance diagnosis and care in resource-limited settings.
OBJECTIVE
This study aims to present a telemedicine web platform, BITScreen PTB (Biomedical Image Technologies Screen for Pediatric Tuberculosis), aimed at improving the evaluation of pulmonary TB in children based on digital chest x-ray (CXR) imaging and clinical information in resource-limited settings.
METHODS
The platform was evaluated by 3 independent expert readers through a retrospective assessment of a data set with 218 imaging examinations of children under 3 years of age, selected from a previous study performed in Mozambique. The key aspects assessed were the usability through a standardized questionnaire, the time needed to complete the assessment through the platform, the performance of the readers to identify TB cases based on the CXR, the association between the TB features identified in the CXRs and the initial diagnostic classification, and the interreader agreement of the global assessment and the radiological findings.
RESULTS
The platform's usability and user satisfaction were evaluated using a questionnaire, which received an average rating of 4.4 (SD 0.59) out of 5. The average examination completion time ranged from 35 to 110 seconds. In addition, the study on CXR showed low sensitivity (16.3%-28.2%) but high specificity (91.1%-98.2%) in the assessment of the consensus case definition of pediatric TB using the platform. The CXR finding having a stronger association with the initial diagnostic classification was air space opacification (χ21>20.38, P<.001). The study found varying levels of interreader agreement, with moderate/substantial agreement for air space opacification (κ=0.54-0.67) and pleural effusion (κ=0.43-0.72).
CONCLUSIONS
Our findings support the promising role of telemedicine platforms such as BITScreen PTB in enhancing pediatric TB diagnosis access, particularly in resource-limited settings. Additionally, these platforms could facilitate the multireader and systematic assessment of CXR in pediatric TB clinical studies.

JAMA Network Open Jul 2024Improving end-of-life care in the intensive care unit (ICU) is a priority, but clinically modifiable factors of quality of dying and death (QODD) are seldom identified. (Observational Study)
Observational Study
IMPORTANCE
Improving end-of-life care in the intensive care unit (ICU) is a priority, but clinically modifiable factors of quality of dying and death (QODD) are seldom identified.
OBJECTIVES
To comprehensively identify factors associated with QODD classes of dying ICU patients, emphasizing clinically modifiable factors based on the integrative framework of factors associated with for bereavement outcomes.
DESIGN, SETTING, AND PARTICIPANTS
This observational cohort study was conducted at medical ICUs of 2 Taiwanese medical centers from January 2018 to March 2020 with follow-up through December 2022. Eligible participants included primary family surrogates responsible for decision making for critically ill ICU patients at high risk of death (Acute Physiology and Chronic Health Evaluation II score >20) but who survived more than 3 days after ICU admission. Data analysis was conducted from July to September 2023.
MAIN OUTCOMES AND MEASURES
QODD was measured by the 23-item ICU-QODD questionnaire. Factors associated with patient membership in 4 previously determined QODD classes (high, moderate, poor to uncertain, and worst) were examined using a 3-step approach for latent class modeling with the high QODD class as the reference category.
RESULTS
A total of 309 family surrogates (mean [SD] age, 49.83 [12.55] years; 184 women [59.5%] and 125 men [40.5%]) were included in the study. Of all surrogates, 91 (29.4%) were the patients' spouse and 66 (53.7%) were the patients' adult child. Patient demographics were not associated with QODD class. Two family demographics (age and gender), relationship with the patient (spousal or adult-child), and length of ICU stay were associated with QODD classes. Patients of surrogates perceiving greater social support were less likely to be in the poor to uncertain (adjusted odds ratio [aOR], 0.89; 95% CI, 0.83-0.94) and worst (aOR, 0.92; 95% CI, 0.87-0.96) QODD classes. Family meetings were associated with the poor to uncertain QODD class (aOR, 8.61; 95% CI, 2.49-29.74) and worst QODD class (aOR, 7.28; 95% CI, 1.37-38.71). Death with cardiopulmonary resuscitation was associated with the worst QODD class (aOR, 7.51; 95% CI, 1.12-50.25). Family presence at patient death was uniformly negatively associated with the moderate QODD class (aOR, 0.16; 95% CI, 0.05-0.54), poor to uncertain QODD class (aOR, 0.21; 95% CI, 0.05-0.82), and worst QODD class (aOR, 0.08; 95% CI, 0.02-0.38). Higher family satisfaction with ICU care was negatively associated with the poor to uncertain QODD class (aOR, 0.93; 95% CI, 0.87-0.98) and worst QODD class (aOR, 0.86; 95% CI, 0.81-0.92).
CONCLUSIONS AND RELEVANCE
In this cohort study of critically ill patients and their family surrogates, modifiable end-of-life ICU-care characteristics played a more significant role in associations with patient QODD class than did immutable family demographics, preexisting family health conditions, patient demographics, and patient clinical characteristics, thereby illuminating actionable opportunities to improve end-of-life ICU care.

We present the case of a patient with newly diagnosed high-risk prostate cancer. The patient underwent nephrectomy for renal cell carcinoma (RCC) in 2009. The prostate-specific membrane antigen (PSMA) scan revealed a primary tumor with seminal vessel involvement, PSMA-positive regional lymph nodes, several nodular lung lesions with mild PSMA uptake, PSMA-positive mediastinal lymph nodes, and a PSMA-positive mass in the pancreatic head. Ultrasound-guided biopsy was performed for the pancreatic lesions revealing metastasis from a RCC. Simultaneous treatment for prostate cancer and metastatic RCC was initiated. To separate metastatic sites for both primaries, we attempted to use fluorodeoxyglucose positron emission tomography/computed tomography, which was moderately positive for the pancreatic mass but not for the other locations. RCC is a Ga PSMA-positive tumor; the synchronous combination of RCC with prostate cancer can be confusing and requires more complex clinical interpretation.

A 58-year-old man presenting with dyspnea, weight loss, and night sweating underwent F-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT) because of a suspicion of malignancy. F-FDG PET/CT demonstrated mild to moderate uptake on nasal, cricoid, and tracheobronchial tree cartilages and costovertebral junctions. The diagnosis was relapsing polychondritis, which is a rare multisystem disease characterized by inflammation of cartilage. In addition, subsequent F-FDG PET/CT after treatment showed complete metabolic response.

OBJECTIVES
To quantitatively evaluate the performance of the most used colormaps in image display using perceptual metrics and to what extent these measures are congruent with the true intensity or uptake of pixels at different levels of defect severity in simulated cardiac images.
METHODS
Six colormaps, labeled "Gray", "Thermal", "Cool", "CEqual", "Siemens" and "S Pet" extracted from FIJI ImageJ software are included. Colormap data are converted from the red, green, blue color space to CIELAB. Perceptual metrics for measuring "color difference" were calculated, including difference (ΔE) and "speed". The pairwise color difference in every two levels or entries is visualized in a 2-dimensional "heatmap distance matrix" for each colormap. Curves are plotted for each colormap and compared. In addition, to apply this technique to clinical images, simulated short-axis cardiac slices with incremental defect severity (10% grading) were employed. The circumferential profile curves of true pixel intensity, lightness or luminance, and color difference are plotted simultaneously for each defect severity to visualize the concordance of the three curves in various colormaps.
RESULTS
In 0% defect, all the curves are at the highest level, except for "s pet", in that the lightness is not at its maximum value. In the phantom with 10% defect (or 90% of maximum value), discrepancies among curves appear. In "Siemens", the ΔE drops sharply. In "Siemens" colormap, the ΔE drops sharply. In 80% defect, ΔE curve, in "gray" colormap drops more slowly than other curves of other colormaps. In "s pet", lightness curve rises paradoxically, although the count intensity and ΔE curve match. In 70% defect, again, the curves are in good agreement in "thermal", "Siemens" and "cequal". However, a consistent lag exists in "gray". Up to 50% defect, curves maintain their expected pattern, but in defects more severe than 40%, lightness and ΔE curves in "cool" and "cequal" rise paradoxically, and in "thermal", they start to slow down in descent. In "Siemens", falling pattern of the three curves continues. For "s pet" colormap, an erratic pattern of lightness and ΔE curves exists.
CONCLUSION
Of 6 colormaps investigated for estimating defect severity, "grayscale" is less favorable than others and "thermal" performs slightly better. "S pet" or rainbow, which is used traditionally by many practitioners, is strongly discouraged. The "Siemens" colormap suffers from decreased discriminating power in the range of mild to moderate/severe. In contrast, the "cool" and "cequal" colormaps outperform the other colormaps employed in this study to some extent, although they have some shortcomings.

PURPOSE
The combination of pharmacological and non-pharmacological interventions is strongly recommended by current guidelines for knee osteoarthritis. However, few systematic reviews have validated their combined efficacy. In this study, we investigated the effects of the combination of pharmacological agents and exercise on knee osteoarthritis.
METHODS
Randomized controlled trials that investigated the efficacy of pharmacological agents combined with exercise for knee osteoarthritis were searched in PubMed, Embase, and Cochrane Library up to February 2024. The network meta-analysis was performed within the frequentist framework. Standardized mean difference (SMD) with 95% CI was estimated for pain and function. Grading of recommendations, assessment, development, and evaluations were used to evaluate the certainty of evidence.
RESULTS
In total, 71 studies were included. The combination therapy outperformed pharmacological or exercise therapy alone. Among the various pharmacological agents combined with exercise, mesenchymal stem cell injection was ranked the best for short-term pain reduction (SMD: -1.53, 95% CI: -1.92 to -1.13, high certainty), followed by botulinum toxin A, dextrose, and platelet-rich plasma. For long-term pain relief, dextrose prolotherapy was the optimal (SMD: -1.76, 95% CI: -2.65 to -0.88, moderate certainty), followed by mesenchymal stem cells, platelet rich in growth factor, and platelet-rich plasma.
CONCLUSION
Exercise programs should be incorporated into clinical practice and trial design. For patients undergoing exercise therapies, mesenchymal stem cell, dextrose, platelet-rich plasma, platelet rich in growth factor, and botulinum toxin A may be the optimal agents.

JPMA. the Journal of the Pakistan... Jun 2024To identify the social intelligence of medical educationists, and the coping strategies used to deal with workplace challenges.
OBJECTIVES
To identify the social intelligence of medical educationists, and the coping strategies used to deal with workplace challenges.
METHODS
The mixed-method study with an explanatory sequential design was conducted from March 15 to July 30, 2021, after approval from the ethics review committee of Riphah International University, Rawalpindi, Pakistan, and comprised medical educationists working in medical and dental colleges and institutions across the country. Data was collected using Tromso social intelligence scale in the quantitative phase. The socially intelligent educationists were identified, and were interviewed. Qualitative data was subjected to thematic analysis to identify predominant themes explaining the coping strategies used.
RESULTS
In the quantitative phase, there were 80 participants; 51(63.7%) females and 29(36.3%) males, with 24(30%) having >10 years of professional experience. Of them, 11(13.8%) scored low, 54(67.5%) moderate and 15(18.8%) high on the social intelligence scale. In the qualitative phase, there were 13 subjects; 9(69.2%) females and 4(30.8%) males. There were 4 themes identified as coping strategies; inspire respect and trust, bringing readiness before a change, a collaborative and inclusive approach and use of soft skills.
CONCLUSIONS
Variation was seen in the levels of social intelligence among medical educationists working in academic institutions. Those with high levels of social intelligence used their non-cognitive soft skills to manage workplace challenges.

JPMA. the Journal of the Pakistan... Jun 2024To determine the effect of disease activity on clinical outcomes of coronavirus disease-2019 in patients with rheumatic diseases.
OBJECTIVES
To determine the effect of disease activity on clinical outcomes of coronavirus disease-2019 in patients with rheumatic diseases.
METHODS
The prospective, cohort study was conducted from January 1st to June 30th, 2021, at Rheumatology department, Fauji Foundation Hospital, Rawalpindi. It comprised patients of rheumatic disorders who were affected by coronavirus disease-2019. The patients were categorised according to rheumatic disease activity into remission group I, low disease activity group II, moderate group III and high-activity group IV. Coronavirus disease-2019 outcomes compared included recovered vs death, hospitalisation yes vs no, mechanical ventilation yes vs no. The association of disease activity status with coronavirus disease-2019 outcomes was explored. Data was analysed using SPSS 23.
RESULTS
Of the 100 patients, 78(78%) were females and 22(22%) were males. The overall mean age was 45.60±13.7 years. There were 23(23%) patients in group I, 42(42%) patients in group II, 21(21%) patients in group III and 14(14%) patients in group IV. Overall,17(17%) patients died and 83(83%) patients survived. In group III, 7(33.3%) patients died, followed by 6(42.9%) in group IV (p<0.05). In total, 7(7%) patients needed mechanical ventilation, with 3(21.4%) being in group IV (p<0.05). Hospitalisation was needed in 33(33%) cases, and intergroup comparison was non-significant (p>0.05).
CONCLUSIONS
Patients with severe rheumatic autoimmune disease affected by coronavirus disease-2019 were more likely to die and require invasive ventilation.

OBJECTIVES
This study aimed to compare the effectiveness of local ozone (O) injection versus corticosteroid injection in the treatment of mild to moderate carpal tunnel syndrome (CTS).
PATIENTS AND METHODS
This double-blind randomized controlled trial was performed on 42 patients (9 males, 33 females; mean age: 46.7±2.1 years; range, 18 to 70 years) with mild to moderate CTS between May 2021 and June 2021. The corticosteroid group (n=21) was injected with 40 mg triamcinolone, and in the O group B (n=21), 4 mL of a 10 mcg/mL oxygen (O)-O mixture was injected. Symptom severity and functional impairments were assessed using a Visual Analog Scale and Boston Carpal Tunnel Questionnaire. Electrodiagnostic and ultrasonographic parameters were obtained at baseline and eight weeks after the procedure.
RESULTS
The O-O solution improved pain and Boston Carpal Tunnel Questionnaire score after eight weeks (p<0.001); however, the change was nonsignificant compared to the corticosteroid group (p>0.05). Sensory nerve and compound muscle action potential latencies were not significantly changed eight weeks after O-O injection (p>0.05), while both were significantly decreased in the steroid injection group (p<0.001). Volar bulging and median nerve cross-section surface area were not improved after O-O injection, while the improvement was significant in the corticosteroid arm (p=0.02).
CONCLUSION
Symptoms in patients with mild to moderate CTS may be alleviated by local O-O injection; however, electrodiagnostic and ultrasonographic indices may be unchanged. Corticosteroid local injection may alleviate patient symptoms along with electrodiagnostic and ultrasonographic parameters.

BACKGROUND
Telephobia is a kind of anxiety disorder in which the individual is afraid of either answering or making telephone calls. This study was conducted to determine the prevalence of telephobia among medical students and to determine the association of socio-demographic and other factors with this disorder.
METHODS
A total of 320 undergraduate medical students were enrolled at a tertiary medical college in Western India, of which 300 (93.75%) responded to the survey. A stratified sampling strategy with the proportional allocation method was used in which 40 males and 20 females were selected from each year of students, spanning 5 years. A specially designed semi-structured questionnaire was used for the study, consisting of demographic data, purpose of using the internet, gadget used, and a 10-item telephobia questionnaire modified from the Severity Measure for Agoraphobia-Adult (SMA-A) Questionnaire to measure student's avoidance of telephone calling and receiving.
RESULTS
The mean age of the study participants was 21.91 (±1.84) years, and most of the students were urban residents (184, 61.3%). The prevalence of mild, moderate, and severe telephobia was 33.0%, 7.67%, and 1.33%, respectively, giving an overall prevalence of 42%. Univariate analysis revealed that male gender (χ = 9.822, df = 3, = 0.0201), higher duration of internet usage (χ = 41.15, df = 9, value < 0.000), and viewing porn (χ = 15.94, df = 3, = 0.0011) had significant association with higher severity of telephobia. Viewing of porn sites was reported by 65 (21.7%) medical students, exclusively among males.
CONCLUSION
A prevalence of 9% moderate to severe telephobia among medical students is much alarming, which may aggravate further as the students move from academic to clinical settings. The phenomenon of telephobia needs further exploration, to find its determinants and predictors, especially among vulnerable populations.
