Objectives: Tuning fork vibration sensation testing is widely used as a diagnostic test to detect diabetic neuropathy. However, evidence-based literature indicates that reliability between examiners is low. Attaching isosceles triangle diagrams on tuning forks lowers the discrepancy between examiners. This study aimed to analyze the relationship between vibration sensation measurement using an improved tuning fork and the presence of callus and wound development in patients with diabetic peripheral neuropathy. Methods: Participants included 56 general older adults and 52 patients with diabetic peripheral neuropathy. The methods included confirmation of the presence or absence of callus, range of motion of the ankle and the first metatarsophalangeal joint, vibratory sensitivity of the medial malleolus and the dorsal aspect of the first distal phalanx using an improved tuning fork, and touch-pressure sensitivity of the plantar aspect of the hallux. Patients with diabetic peripheral neuropathy were followed up for 3 years to check for the presence or absence of wounds. Results: When compared with the general older adults, the patients with diabetic peripheral neuropathy had significantly lower touch-pressure sensitivity ( p < 0.01), vibratory sensitivity at the distal phalanx ( p < 0.01) and medial malleolus ( p < 0.01), ankle dorsiflexion range of motion ( p < 0.01), and metatarsophalangeal joint extension range of motion ( p < 0.01). The area under the receiver operating characteristic curve with callus formation was 0.93 for the medial malleolus and 0.96 for the distal phalanx, indicating that the accuracy of the distal phalanx was higher ( p < 0.01) than the medial malleolus. According to the Cox proportional hazard analysis, the vibratory sensitivity of the distal phalanx was a significant risk factor for ulcer development ( p < 0.05). Conclusion: These findings suggest that the vibration sensation test, which we improved via the technique described in this study, is useful for predicting the occurrence of callus and ulcer.

Background: The association of SARS-CoV-2 with acute otitis media (AOM) in children is poorly understood. Methods: Cases were identified as a subpopulation within the NO TEARS prospective AOM study in Denver, CO from March to December 2020. Children enrolled were 6 to 35 months of age with uncomplicated AOM; those with AOM and SARS-CoV-2 were included. Data was obtained from electronic medical records and research case report forms. Results: A total of 108 patients enrolled in the NO TEARS study from May 2019 through December 2020 (all subsequently tested for SARS CoV-2). During the COVID-19 pandemic study period (March-December 2020), 16 patients enrolled, and 7 (43.6%) were identified with AOM/COVID-19 co-infection. Fever was present in 3 of 7 children (29%). Four children (57%) attended daycare. Only 2 children (29%) had SARS CoV-2 testing as part of their clinical workup. Mean AOM-SOS© scores were similar among SARS CoV-2 positive and negative patients with no statistical significance with two-sided t-tests: 13.6 (±4.5) versus 14.2 (±4.9) at enrollment, 1.4 (±1.8) versus 4.2 (±4.9) on Day 5, and 0.6 (±0.9) versus 2.5 (±6.1) on Day 14. Among the 7 cases, no child had an AOM treatment failure or recurrence within 3 to 14 or 15 to 30 days respectively. Of the 6 patients with completed bacterial and viral testing, a bacterial pathogen was identified in all 6, and a viral pathogen in 3 (50%). Conclusions: COVID-19 and AOM can co-exist. Providers should maintain a high index of suspicion for COVID-19 even in patients with clinical AOM and should not use a diagnosis of AOM to exclude COVID-19.
Comments on the Paper ‘The Optimal Distribution Rule of Federal Funds to States in India: A Suggested Methodology’ by Raychaudhuri and Roy (2021)
Authors: Sinha Sudip Kumar 
Published: March 2022

The recent paper by Raychaudhuri and Roy (2021) in the South Asian Journal of Macroeconomic and Public Finance has been both timely and intensely thought provoking as it suggests an alternative approach for intergovernmental fiscal transfer in India. Fiscal transfers to subnational governments by the Finance Commissions in India is critical for maintaining the spirit of co-operative fiscal federalism in the country and is designed to improve the overall fiscal health of the economy. Rewarding the states for their efforts in improving public investment management would certainly help make the devolution rules for the Finance Commission time consistent and truly welfare- and growth oriented, and it would also help address the issue of vertical and horizontal gap in a more sustainable manner.

Published: March 2022

Background: Both knotted and knotless single-anchor repair techniques are used to repair transmural ruptures of the upper subscapularis (SSC) tendon. However, it is still unclear which technique provides better clinical and radiological results. Purpose/Hypothesis: To compare the clinical and magnetic resonance imaging (MRI) outcomes of knotless and knotted single-anchor repair techniques in patients with a transmural rupture of the upper SSC tendon at 2-year follow-up. It was hypothesized that the 2 techniques would not differ significantly in outcomes. Study Design: Cohort study; Level of evidence, 3. Methods: Forty patients with a transmural tear of the upper SSC tendon (grade 2 or 3 according to Fox and Romeo) were retrospectively enrolled. Depending on the repair technique, patients were assigned to either the knotless single-anchor or knotted single-anchor group. After a mean follow-up of 2.33 ± 0.43 years, patients were assessed by the ASES, WORC, OSS, CS, and SSV. A clinical examination that included the bear-hug, the lift-off, and the belly-press tests was performed, in which the force exerted by the subjects was measured. In addition, all patients underwent MRI of the affected shoulder to assess repair integrity, tendon width, fatty infiltration, signal-to-signal ratio of the upper and lower SSC muscle, and atrophy of the SSC muscle. Results: No significant difference was found between the 2 groups on any of the clinical scores [ASES ( P = .272), WORC ( P = .523), OSS ( P = .401), CS ( P = .328), SSV ( P = .540)] or on the range-of-motion or force measurements. Apart from a higher signal-to-signal ratio of the lower SSC muscle in the knotless group ( P = .017), no significant difference on imaging outcomes was found between the 2 groups. Conclusion: Both techniques can be used in surgical practice, as neither was found to be superior to the other in terms of clinical or imaging outcomes at 2-year follow-up.

AbstractBreeding rice (Oryza sativa L.) with high yield, superior quality, desired grain shape and high resistance is the goal of breeding to meet the needs of current consumers. It is usually hard to combine multiple complex traits based on traditional breeding methods because they are frequently antagonistic to each other. However, molecular design breeding, as a novel breeding method, is an optional alternative to this challenge. To demonstrate molecular design breeding, 15 favorable genes from five parent lines were pyramided together to develop elite rice with high-yield, superior-quality, desired grain shape and high resistance to brown planthopper (BPH). The parental lines were 9311, the recurrent parent, carrying APO1, Ghd7, Ghd8 and Gn1a for high yield, GS3 and qSW5 for grain shape, and Wx and ALK for eating and cooking quality; 1880 with Gn8.1 for large panicles; Luo-Yu-Xiang carrying GW7 for grain shape and SBE3, SSIV2 and SSIII for eating and cooking quality; Luoyang6 with Bph6 and Luoyang9 with Bph9 for BPH resistance. After careful screening for the 15 targeted genes, desired phenotype and maximum genetic background from 9311, three molecular design lines with desired phenotypes, named as MD1 (Molecular design 1), MD2 and MD3 were developed. MD3 carried all 15 targeted genes, and MD1 and MD2 had 14 of the 15 targeted genes. Only SBE3 was not introgressed into MD1 and MD2 but this had minimal impact on the gel consistency and alkali spreading value. These newly bred lines exhibited higher yield potential, better grain quality with slender grains, low amylose content, high gel consistency and alkali spreading value, and higher BPH resistance compared to the parent 9311. In this study, we successfully created three novel rice lines with high yield, superior quality and improved BPH resistance by rational molecular design. Our results demonstrate molecular design is a powerful strategy to improve multiple complex traits and will provide a reference for the future commercial rice improvement.

AbstractBackgroundLongitudinal data analysis can improve our understanding of the influences on health trajectories across the life-course. There are a variety of statistical models which can be used, and their fitting and interpretation can be complex, particularly where there is a nonlinear trajectory. Our aim was to provide an accessible guide along with applied examples to using four sophisticated modelling procedures for describing nonlinear growth trajectories.MethodsThis expository paper provides an illustrative guide to summarising nonlinear growth trajectories for repeatedly measured continuous outcomes using (i) linear spline and (ii) natural cubic spline linear mixed-effects (LME) models, (iii) Super Imposition by Translation and Rotation (SITAR) nonlinear mixed effects models, and (iv) latent trajectory models. The underlying model for each approach, their similarities and differences, and their advantages and disadvantages are described. Their application and correct interpretation of their results is illustrated by analysing repeated bone mass measures to characterise bone growth patterns and their sex differences in three cohort studies from the UK, USA, and Canada comprising 8500 individuals and 37,000 measurements from ages 5–40 years. Recommendations for choosing a modelling approach are provided along with a discussion and signposting on further modelling extensions for analysing trajectory exposures and outcomes, and multiple cohorts.ResultsLinear and natural cubic spline LME models and SITAR provided similar summary of the mean bone growth trajectory and growth velocity, and the sex differences in growth patterns. Growth velocity (in grams/year) peaked during adolescence, and peaked earlier in females than males e.g., mean age at peak bone mineral content accrual from multicohort SITAR models was 12.2 years in females and 13.9 years in males. Latent trajectory models (with trajectory shapes estimated using a natural cubic spline) identified up to four subgroups of individuals with distinct trajectories throughout adolescence.ConclusionsLME models with linear and natural cubic splines, SITAR, and latent trajectory models are useful for describing nonlinear growth trajectories, and these methods can be adapted for other complex traits. Choice of method depends on the research aims, complexity of the trajectory, and available data. Scripts and synthetic datasets are provided for readers to replicate trajectory modelling and visualisation using the R statistical computing software.
Dermoscopy use in primary care: a qualitative study with general practitioners
Authors: Fee Jonathan A. , McGrady Finbar P. , Hart Nigel D. 
Published: March 2022

Abstract
Background
Skin assessments constitute a significant proportion of consultations with family physicians (commonly called general practitioners or GPs in the UK), and referrals to hospital dermatology departments have risen significantly in recent years. Research has shown that dermoscopy use may help GPs to assess and triage skin lesions, including suspected skin cancers, more accurately. However, dermoscopy is used by a small minority of GPs in the UK. Previous questionnaire studies have aimed to establish in a limited way some perceptions of dermoscopy among GPs: this study aimed to explore more deeply the factors influencing the use of dermoscopy among GPs.

Methods
This was a qualitative interview study set in UK general practice. A purposive sample was taken of GPs who were established dermoscopy users, GPs who had recently adopted dermoscopy, and those who did not use dermoscopy. A total of twelve semi-structured interviews were conducted. Audio-recordings were transcribed verbatim and analysed using a thematic analysis (Braun and Clarke).

Results
GPs’ capability to use dermoscopy necessitated receiving adequate training, while previous dermatology experience and support from colleagues were also considered factors that enabled dermoscopy use. The impact of dermoscopy on patient consultations about skin complaints was generally considered to be positive, as was having an ‘in-house’ dermoscopy user within a GP practice to refer patients to. However, training in dermoscopy was not considered a priority for many GPs either due to other more pressing concerns within their practices or the perceived complexity of dermoscopy, alongside barriers such as equipment costs. Significant ethical concerns with posting patient photographs online for training and teaching purposes were also highlighted.

Conclusions
Both GPs who use dermoscopy, and those who do not, consider it to have an important role in improving skin assessments within primary care. However the need for adequate training in dermoscopy and dermatology more generally was highlighted as a key barrier to its wider use. The development of competency standards for the use of dermoscopy could allow the adequacy of training to be assessed and developed.
Correlation between hand grip strength and regional muscle mass in older Asian adults: an observational study
Authors: Chan Jessica , Lu Yi-Chien , Yao Melissa Min-Szu , Kosik Russell Oliver 
Published: March 2022

Abstract
Background
Previous research has demonstrated a correlation between hand grip strength (HGS) and muscle strength. This study aims to determine the relationship between HGS and muscle mass in older Asian adults.

Methods
We retrospectively reviewed the dual-energy X-ray absorptiometry (DXA) records of 907 older adults (239 (26.4%) men and 668 (73.6%) women) at one medical institution in Taipei, Taiwan, from January 2019, to December 2020. Average age was 74.80 ± 9.43 and 72.93 ± 9.09 for the males and females respectively. The inclusion criteria were: 1) aged 60 and older, 2) underwent a full-body DXA scan, and 3) performed hand grip measurements. Patients with duplicate results, incomplete records, stroke history, and other neurological diseases were excluded. Regional skeletal muscle mass was measured using DXA. HGS was measured using a Jamar handheld dynamometer.

Results
Total lean muscle mass (kg) averaged 43.63 ± 5.81 and 33.16 ± 4.32 for the males and females respectively. Average HGS (kg) was 28.81 ± 9.87 and 19.19 ± 6.17 for the males and females respectively. In both sexes, HGS and regional muscle mass consistently declined after 60 years of age. The rates of decline per decade in upper and lower extremity muscle mass and HGS were 7.06, 4.95, and 12.30%, respectively, for the males, and 3.36, 4.44, and 12.48%, respectively, for the females. In men, HGS significantly correlated with upper (r = 0.576, p < 0.001) and lower extremity muscle mass (r = 0.532, p < 0.001). In women, the correlations between HGS and upper extremity muscle mass (r = 0.262, p < 0.001) and lower extremity muscle mass (r = 0.364, p < 0.001) were less strong, though also statistically significant.

Conclusion
Muscle mass and HGS decline with advancing age in both sexes, though the correlation is stronger in men. HGS measurements are an accurate proxy for muscle mass in older Asian adults, particularly in males.
Variations in physical activity and sedentary behavior during and after hospitalization in acutely admitted older medical patients: a longitudinal study
Authors: Jawad Baker Nawfal , Petersen Janne , Andersen Ove , Pedersen Mette Merete 
Published: March 2022

Abstract
Background
Inactivity is frequent among older patients during hospitalization. It is unknown how patients' daily activity pattern (diurnal profile) vary between hospitalization and after discharge. This study aims to describe and compare the distribution of physical activity and sedentary behavior in acutely hospitalized older patients during hospitalization and after discharge.

Methods
We included data on 80 patients (+65 years) admitted with acute medical illness from the STAND-Cph trial. Physical activity and sedentary behavior were measured as daily number of steps, uptime (walking/standing) and sedentary behavior (lying/sitting) with an activity monitor (activPAL3, PAL Technologies Ltd). The patients wore the monitor for three periods of one week: during hospitalization, after discharge, and four weeks after discharge.

Results
The patients’ median age was 80 years [IQR: 75;88], 68% were female and the median De Morton Mobility Index (DEMMI) was 57 [IQR: 48;67]. The daily median uptime was 1.7 h [IQR: 1;2.8] during hospitalization, 4.0 h [IQR: 2.7;5.4] after discharge and 4.0 h [IQR: 2.8;5.8] four weeks after discharge. The daily median number of steps was 728 [IQR: 176;2089], 2207 [IQR: 1433;3148], and 2622 [IQR: 1714;3865], respectively, and median daily sedentary behavior was 21.4 h (IQR: 20.7;22.4), 19.5 h (IQR: 18.1;21.0) and 19.6 h (IQR: 18.0;20.8), respectively. During hospitalization, a small activity peak was observed between 9-11 AM without any notable variation after. At discharge and four weeks after discharge, a peak in physical activity was seen between 9-12 AM and at 5 PM.

Conclusion
Older hospitalized patients spend most of their time being sedentary with their highest activity between 9-11 AM. Daily activity doubles after discharge with one extra peak in the afternoon. Daily routines might be disrupted, and older patients have the potential to be more physically active during hospitalization. Interventions that encourage physical activity during hospitalization are warranted.
Response rate of anticancer drugs approved by the Food and Drug Administration based on a single-arm trial
Authors: Oda Yoshihiro , Narukawa Mamoru 
Published: March 2022

Abstract
Background
In recent years, an increasing number of anticancer drugs have been approved based on the results of a single-arm trial (SAT). The magnitude of the objective response rate (ORR) in SATs is important for regulatory decisions, but there has been no clear guidance specifying the degree of ORR for approval.

Methods
All anticancer drugs approved by the US Food and Drug Administration (FDA) between January 2016 and December 2019 were identified through the FDA website. From these, we selected drugs approved for solid tumors based on SATs. For each indication, one regimen was selected from the standard-of-care as the best comparison therapy (BCT), which was defined as the latest regimen for the same tumor and treatment line. We compared the ORR of the investigated product with that of the BCT.

Results
Of the 31 solid tumor indications identified, we selected BCT for 28. In 23 of the 28 indications (82.1%), the ORR of the investigated product exceeded that of the BCT, and in 16 of these (69.6%), the lower limit of the 95% confidence interval (CI) of the ORR of the investigated product exceeded the point estimate of the BCT ORR. For seven products, the lower limit of the 95% CI was below the point estimate of the BCT ORR, with differences ranging from 1.0% to 3.4%.

Conclusion
The lower limit of a 95% CI of the ORR of a new drug in an SAT exceeding the point estimate of the BCT ORR could be an important factor in obtaining regulatory approval.

Published: March 2022

Abstract
Background
In neonatology, parents play a central role as guarantors of the new-born’s autonomy. Notifying parents about their infant’s status in neonatal critical care is an integral part of the care. However, conveying this information can be very difficult for physicians and the neonatal medical team.
The objective of this work is to assess the dimensions and dynamic processes of critical care communications in neonatal intensive care in order to enhance the development of theoretical and applied knowledge of these discussions.

Methods
This qualitative, descriptive study was conducted on critical care new-borns less than 28 days-old who were hospitalized in a neonatal intensive care unit. Verbatim communications with the parents were recorded using a dictaphone.

Results
The verbatim information had five themes: (a) critical care, (b) establishing the doctor-patient relationship, (c) assistance in decision making, (d) Socio-affective and (e) socio-symbolic dimensions. Our recordings underscored both the necessity of communication skills and the obligation to communicate effectively. Analysis of the dynamics of the communication process, according to the categories of delivering difficult information, showed few significant differences.

Conclusion
Physician training needs to include how to effectively communicate to parents to optimize their participation and cooperation in managing their care.
