Abstract
Background:
Cardiac rehabilitation (CR) improves physical activity (PA) and reduces morbidity for patients with cardiovascular disease. We understand little of baseline PA as patients initiate CR, particularly when outside of CR. We used mobile health (mHealth) technology to understand baseline PA of patients initiating CR within a clinical trial to potentially inform personalized care.
Methods:
The Virtual AppLication-Supported Environment to INcrease Exercise During Cardiac Rehabilitation Study (VALENTINE) Study is a prospective, randomized-controlled, remotely administered trial designed to evaluate an mHealth intervention to supplement CR for low- and moderate-risk patients. Participants are randomized after 2 CR sessions; all receive a smartwatch and usual care. Remotely administered baseline PA outcomes include 6-minute walk distance, step count, and exercise minutes. Baseline PA was assessed for 7-days after study enrollment for compliant days, defined by
>
8 hours of watch wear/day. Multivariable linear regression identified features associated with baseline PA.
Results:
From October 19, 2020 to January 31, 2022, 180 participants enrolled. Participants are mostly White [156 (86.7%)]; 59 (32.8%) are female and 69 (38.3%) are
>
65 years old. Most enrolled in CR after coronary revascularization [114 (64.4%)] or valve intervention [40 (22.2%)]. Comorbidities include hypertension (65.0%), valve disease (35.6%), and heart failure (17.8%). Participants were compliant for 91.4% of days with 15.3 (4.0) hours/compliant day. Baseline PA included 6-minute walk distance of 491.8 (147.8) meters, daily step count of 6818 (3386), and exercise minutes of 36.0 (33.4). Substantial variation in baseline PA assessed by 6-minute walk distance was noted across age and gender but not CR indication.
Conclusions:
Understanding baseline PA as participants enroll in CR may be useful in personalizing CR programs at initiation and designing mHealth interventions.

Gupta K, Jansen EC, Campos H, Baylin A. Associations between sleep duration and Mediterranean diet score in Costa Rican adults. Appetite 2022; 170:105881. [PMID: 34942284 PMCID: PMC8761173 DOI: 10.1016/j.appet.2021.105881] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Revised: 12/06/2021] [Accepted: 12/17/2021] [Indexed: 12/26/2022]
Abstract
Both insufficient and excessive sleep duration have been associated with lower-quality diets in adult populations. However, investigations in Latin America, where different sleep norms may exist (e.g., daily napping), are scarce. Therefore, we examined whether weekday sleep duration and inconsistencies between weekday and weekend sleep duration were related to adherence to the Mediterranean diet among Costa Rican adults. The study population included 2169 controls (74% men) from a population-based case-control study. Usual sleep duration (weekday versus weekend) was self-reported and defined as short, recommended, and long (<7 h, 7-9 h, >9 h, respectively). Inconsistent weekday-weekend sleep duration was defined as >1-h difference. Diet was assessed with a food frequency questionnaire, and adherence to the Mediterranean diet was calculated with the Alternative Mediterranean Diet Score (AMED). Sex-stratified linear regression models were conducted with AMED score as a continuous outcome and sleep variables as categorical or dichotomous exposures (in separate models). Models were adjusted for age, area of residence, education, napping, caffeine intake, smoking status, type 2 diabetes mellitus, hypertension, and physical activity. Average (SD) hours of sleep per night reported were 7.0 (1.4) on weekdays and 7.3 (1.6) on weekends for men, and 7.0 (1.5) on weekdays and 7.2 (1.6) on weekends for women. Among women, sleep duration <7-h per night was associated with a lower AMED score compared to those with recommended sleep duration (β: -0.35, CI: -0.63 to -0.07). Unstratified models showed a suggestive association between inconsistent weekday-weekend sleep and lower AMED scores that did not vary by sex (β: -0.08, CI: -0.16, 0.006; P, interaction with sex = 0.93). Lastly, the napping frequency was not associated with AMED scores in any model. In conclusion, short and inconsistent sleep duration may affect the dietary patterns of Costa Ricans.

Abstract
Background Hairdressers undergo extensive and prolonged exposure to a variety of chemical substances present in the air in their salons. Although in low concentrations, the various products used for hair care are harmful as most of these products generate chemical aerosols during different procedures. These aerosols which have irritant or sensitizing effects on respiratory mucosa have been found to enter into the airways. Aim The aim of this study is to assess the impairment of lung function in hairdressers in Gangtok. Method This is a cross-sectional, comparative study conducted on 50 hairdressers and 50 age- and sex-matched non-hairdresser comparison group. The sampling technique used was simple random sampling. Permission from Institutional Ethical Committee was obtained before beginning the study. A standard questionnaire was used to record the respiratory symptoms. The pulmonary function parameters of the subjects were measured using portable spirometer HELIOS 720. Results All the parameters were decreased in hairdressers and almost all the differences were statistically significant. FEV1 (P = 0.023) and FEV1/FVC ratio (P < 0.05) were reduced significantly. FEF25-75% and PEFR were also significantly reduced (P < 0.05 in both parameters). FVC was also reduced in hairdressers, but it was not statistically significant (P = 0.342). Conclusion Hairdressers undergo exposure to different chemicals in their workplace and carry the risk of decreased pulmonary function.

Abstract
OBJECTIVE The rational use of medicines as per the World Health Organization (WHO) should be practiced globally. However, data regarding the completeness of the prescriptions and their rational use is lacking from developing countries like India. Thus, the aim of this study was to assess the prescribing patterns of drugs and completeness of prescriptions as per WHO core drug use and complementary indicators to provide real-life examples for the Indian Council of Medical Research (ICMR) online prescribing skill course for medical graduates. METHODS Prescriptions of the patients, fulfilling inclusion criteria, attending Outpatient Departments of various specialties of tertiary care hospitals, were collected by thirteen ICMR Rational use of medicines centers located in tertiary care hospitals, throughout India. Prescriptions were evaluated for rational use of medicines according to the WHO guidelines and for appropriateness as per standard treatment guidelines using a common protocol approved by local Ethics committees. RESULTS Among 4838 prescriptions, an average of about three drugs (3.34) was prescribed to the patients per prescription. Polypharmacy was noted in 83.05% of prescriptions. Generic drugs were prescribed in 47.58% of the prescriptions. Further, antimicrobials were prescribed in 17.63% of the prescriptions and only 4.98% of prescriptions were with injectables. During the prescription evaluation, 38.65% of the prescriptions were incomplete due to multiple omissions such as dose, duration, and formulation. CONCLUSION Most of the parameters in the present study were out of the range of WHO-recommended prescribing indicators. Therefore, effective intervention program, like training, for the promotion of rational drug use practice was recommended to improve the prescribing pattern of drugs and the quality of prescriptions all over the country.

Abstract
Renal cell cancer (RCC) accounts for 3% of all solid malignancies. Synchronous tumour thrombus in the renal vein or inferior vena cava is reported in 4-10% cases and is a surgical challenge. Contemporary imaging modalities that are used to define the presence and extent of venous thrombus include colour Doppler, contrast-enhanced computed tomography and magnetic resonance venography. Surgical management depends upon the degree of tumour thrombus. We report isolated recurrence of RCC in the inferior vena cava 2 years after radical nephrectomy, and discuss its pathophysiology and management.

Abstract
Abstract
Background
Human cardiac pericytes (PC) were proposed as the main cellular target for SARS-CoV-2 in the heart due to high transcriptional levels of the angiotensin-converting enzyme 2 (ACE2) receptor. Emerging reports indicate CD147/Basigin (BSG), highly expressed in endothelial cells (EC), is an alternative SARS-CoV-2 receptor. To date, the mechanism by which the virus infects and disrupts the heart vascular cells was not identified yet. Moreover, cleaved Spike (S) protein molecules could be released into the bloodstream from the leaking pulmonary epithelial-endothelial barrier in patients with severe COVID-19, opening to the possibility of non-infective diseases in organs distant from the primary site of infection.
Purposes
(1) to confirm that human primary cardiac PC express ACE2 and CD147; (2) to verify if PC are permissible to SARS-CoV-2 infection; (3) to investigate if the recombinant SARS-CoV-2 S protein alone, without the other viral elements, can trigger molecular signalling and induce functional alterations in PC; (4) to explore which viral receptor is responsible for the observed events.
Methods and results
Cardiac PC express both the ACE2 and CD147 receptors at mRNA and protein level. Incubation of PC for up to 5 days with SARS-CoV-2 expressing the green fluorescent protein (GFP) did not show any evidence of cell infection or viral replication. Next, we exposed the PC to the recombinant S protein (5.8 nM) and confirmed that the protein engaged with cellular receptors (western blot analysis of S protein in treated and control PC). Incubation with the S protein increased PC migration (wound closure assay, P<0.01 vs ctrl) and reduced the formation of tubular structures between PC and EC in a Matrigel assay (P<0.01 vs ctrl). Moreover, the S protein promoted the production of pro-inflammatory factors typical of the cytokine storm in PC (ELISA measurement of MCP1, IL-6, IL-1β, TNFα, P<0.05 vs ctrl), and induced the secretion of pro-apoptotic factors responsible for EC death (Caspase 3/7 assay, P<0.05 vs ctrl). Signalling studies revealed that the S protein triggers the phosphorylation/activation of the extracellular signal-regulated kinase 1/2 (ERK1/2) through the CD147 receptor, but not ACE2, in cardiac PC. The neutralization of CD147, using a blocking antibody, prevented ERK1/2 activation in PC, and was reflected into a partial rescue of the cell functional behaviour (migration and pro-angiogenic capacity). In contrast, blockage of CD147 failed to prevent the pro-inflammatory response in PC.
Conclusions
We propose the novel hypothesis that COVID-19 associated heart's microvascular dysfunction is prompted by circulating S protein molecules rather than by the direct coronavirus infection of PC. Besides, we propose CD147, and not ACE2, as the leading receptor mediating S protein signalling in cardiac PC.

Abstract
Abstract
Aim
Incisional hernias (IH) are a known complication of any major abdominal surgery. It is known that chemotherapy impairs healing processes via delayed inflammation, impaired collagen synthesis and reduced fibrin deposition and wound contraction. There are currently, to our knowledge, no trials examining the effect of adjuvant chemotherapy on incidence of IH in patients with colorectal cancer. This study aims to assess the same by comparing IH rates between chemotherapy and non-chemotherapy patient groups.
Method
All the patients who had major surgery for colorectal cancer between January 2009 and January 2014 were divided into two groups of chemotherapy (A) and non-chemotherapy (B). Records of first 160 patients from each group were retrospectively analysed.
Results
There were non-significant differences between groups for sex, tumour location, primary operation, and type of procedure (emergency or elective). Significant differences were observed for age (more elder patients in group B, p = 0.000011), method of access (more open procedures in group B and more laparoscopic procedures in group A, p = 0.0007) and Charlson co-morbidity scores (more advanced score in group B, p = 0.029). We found that 21/120 (21.21%) patients in the chemotherapy group and 12/99 (13.79%) patients in non-chemotherapy group developed Incisional hernias. Although there was a higher rate of IH in the chemotherapy group, this was not statistically significant (p = 0.27).
Conclusions
Although this study fails to demonstrate any statistically significant difference in IH incidence between two groups, but this study can act as a pilot in order to fuel further high-quality research to draw more valid conclusions.

Abstract
INTRODUCTION With tonsillectomy surgery subject to increasingly strict commissioning criteria over the past 20 years in the UK, the total number of admissions for acute tonsillitis has been rising steadily. Multiple single-centre studies have demonstrated how introduction of a standardised management protocol can be effective in improving the delivery of treatment for acute tonsillitis in the emergency department. METHODS Using a novel approach, we aimed to implement an acute tonsillitis management protocol within a formal clinical decisions unit (CDU) pathway. Following a retrospective baseline audit, we carried out two post-intervention cycles of data collection to assess safety and efficacy. RESULTS The median number of initial treatments increased significantly from two of five at baseline, to three of five in both the first (U = 86, p = 0.004) and second (z = 2.959, p = 0.003) audit cycles. Admission rate was reduced from 0.79 to 0.44 in the first cycle, representing a 44.6% relative risk reduction [95% confidence interval (CI) 0.304-1.012; p = 0.0547]. Admission rate remained reduced at 0.48 in the second cycle, with a relative risk reduction of 39.2% compared with baseline (95% CI 0.380-0.972; p = 0.038). CONCLUSIONS Utilisation of the CDU led to an improvement in the delivery of initial treatment, an extended period of observation and subsequently a greater percentage of patients being discharged. An acute tonsillitis management protocol within a CDU appears to be a safe and effective model and is now standard practice in our hospital.

Abstract
Determination of accurate anti-A/-B titers is important for treatment selection in ABO-incompatible stem cell and solid-organ transplants. The standard method for ABO antibody titration is the conventional tube test (CTT). Dithiothreitol (DTT) is commonly used to inactivate the IgM antibody component. The aim of this study was to compare six different methods for ABO antibody titration and to observe the effectiveness of DTT on antibody estimation. A total of 90 healthy voluntary blood donors were enrolled in this study, including 30 each for blood groups A, B, and O. Antibody titrations were performed and tested using the CTT-immediate spin (IS), CTT-antihuman globulin (AHG) with and without DTT, column agglutination technology (CAT)-IS, and CAT-AHG with and without DTT methods. Bead-CAT was used, and the positive cutoff value was set to 1+ for each method to determine the endpoint of the titer. The median values of anti-A/-B titers by IS were found to be higher than those values by AHG in CTT and CAT among group B and A individuals, whereas no statistically significant differences were observed in values from group O individuals for IS and AHG anti-A/-B titers, estimated by each method. Although there was positive correlation between the anti-A/-B titer results obtained using the CTT and CAT in all blood groups, testing using AHG showed poor agreement with and without DTT pretreatment (kappa value of 0.11 and 0.20, respectively). Moderate agreement was observed between CTT-IS and CAT-IS (kappa value of 0.46). Median anti-A/-B AHG titers were reduced by the use of DTT in all blood group samples. Significant differences in the interpretability of anti-A/-B titers were observed among different methods. A uniform approach for selecting the method for ABO antibody titration is highly recommended, and DTT pretreatment of plasma to neutralize IgM activity should be considered to obtain precise values of IgG anti-A/-B titers.

Abstract
Introduction March 11th, 2020 saw the World Health Organisation declare a global pandemic following the eruption of the novel coronavirus disease 2019. Unprecedented global demand for personal protective equipment (PPE) was complicated by limited availability and conflicting guidance from healthcare bodies. This study aimed to assess perceived confidence and knowledge of Public Health England’s PPE guidance amongst doctors of varying specialties and grades. Method A nationwide 11-point survey comprising of multiple-choice questions (MCQs) and a Likert scale assessing perceived confidence (1=not confident, 5=very confident) was disseminated to U.K. based doctors using multiple platforms. Results Data collated from 697 respondents revealed average perceived confidence was low. Notably, 59% felt they had received insufficient education regarding up-to-date guidance, with 81% advocating further training. Anaesthetics and ophthalmology were the highest and lowest scoring specialties in knowledge based MCQs, achieving 59% and 31% respectively. Subsequent statistical analysis revealed significant differences between specialties." Conclusions Ensuring consistency in published PPE guidance and education can develop doctor’s confidence and knowledge of appropriate PPE use. The absence of a unified consensus and global education regarding the use of PPE poses significant ramifications for patient and healthcare professional (HCP) safety whilst risking further depletion of already sparse resources.

Abstract
Peri-operative pain management in the neonate with a sacrococcygeal teratoma poses significant challenges to the anaesthetist. Involvement of the sacrococcygeal area by the tumour often prevents the use of conventional regional anaesthetic techniques such as caudal or epidural analgesia, with a subsequent reliance on intravenous opioids and paracetamol. Since opioids are associated with respiratory depression, constipation and urinary retention, there is high incidence of opiophobia with consequent inappropriate dosage prescription, particularly in the paediatric population. We describe the use of an ultrasound-guided sacral multifidus plane block in two neonates undergoing surgical excision of sacrococcygeal teratoma. The block is technically easy to perform and also avoids traversing critical structures. Hence, it may be regarded as a promising analgesic technique for painful interventions in the sacrococcygeal area.

Abstract
Background Increasingly, it has been seen that patients recovering from COVID-19 may face a second battle of coping with its mental health ramifications. These psychological issues can even be experienced by patients who were asymptomatic or had mild to moderate symptoms, potentially impacting their quality of life. Methodology This was a prospective observational study to analyse the psychological impact of COVID-19 in recovered patients who presented as prospective convalescent plasma (CP) donors. An interview for the psychological assessment of the prospective donors was carried out. Depression and anxiety in the participants were assessed by HAM-A, and HAM-D scores and Quality of Life were assessed using the WHOQOL-BREF scale. Results A total of 51 prospective donors were assessed, with a mean age of 34.37 (±9.08) years, with the majority being males (46). No clinically significant depression and anxiety were found on the basis of HAM-D and HAM-A scores. The worst affected quality of life parameter, based on the WHOQOL-BREF scale, was physical quality of life followed by environmental, psychological, and social relationships. Moreover, due to infection, social stigma was experienced by 49.02% of the donors, while 21.97% had anxiety related to convalescent plasma donation as a common livid experience. Conclusion Poor quality of life and social stigma during the recovery phase is prevalent in COVID-19 recovered patients, for which formulation of holistic support strategies are the need of the hour.

Abstract
BACKGROUND Cognitive impairment in patients with human immunodeficiency virus (HIV) is associated with higher morbidity. The prevalence of the metabolite changes in the brain associated with cognitive impairment in anti-retroviral therapy naïve patients with HIV is unknown. OBJECTIVE To estimate the prevalence of the neurometabolites associated with cognitive impairment in antiretroviral therapy (ART) naïve patients with HIV. METHODS We conducted a cross-sectional study among ART naïve patients with HIV aged 18-50 years in a tertiary care center in India. Cognition was tested using the Post Graduate Institute battery of brain dysfunction across five domains; memory, attention-information processing, abstraction executive, complex perceptual, and simple motor skills. We assessed the total N-acetyl aspartyl (tNAA), creatine (tCr) and glutamate + glutamine (Glx) using 3T magnetic resonance spectroscopy. Cognitive impairment was defined as an impairment in ≥2 domains. RESULTS Among 43 patients eligible for this study, the median age was 32 years (IQR 29, 40) and 30% were women. Median CD4 count and viral load were 317 cells/μL (IQR 157, 456) and 9.3 copies/ μL (IQR 1.4, 38), respectively. Impairment in at least one cognitive domain was present in 32 patients (74.4%). Impairment in simple motor skills and memory was present in 46.5% and 44% of patients, respectively. Cognitive impairment, defined by impairment in ≥2 domains, was found in 22 (51.2%) patients. There was a trend towards higher concentration of tNAA (7.3 vs. 7.0 mmol/kg), tGlx (9.1 vs. 8.2 mmol/kg), and tCr (5.5 vs. 5.2 mmol/kg) in the frontal lobe of patients with cognitive impairment vs. without cognitive impairment but it did not reach statistical significance (p>0.05 for all). There was no difference in the concentration of these metabolites in the two groups in the basal ganglia. CONCLUSION There is a high prevalence of cognitive impairment in ART naïve patients with HIV. There is no difference in metabolites in patients with or without cognitive impairment. Further studies, with longitudinal follow-up are required to understand the underlying pathophysiological mechanisms.

Abstract
BACKGROUND Embryonal tumors with multilayered rosettes (ETMR) is an extremely rare and highly aggressive tumor. It includes three distinct entities i.e, embryonal tumor with abundant neuropil and true rosettes (ETANTR), ependymoblastoma (EBL) and medulloepithelioma (MEPL). Here, we present our institutional experience of seven ETMR cases treated over a period of five years. MATERIALS AND METHODS Patients' records from 2015 to 2019 were reviewed manually and electronically to retrieve the data. Clinicopathological and outcome details of ETMR cases were entered in a predesigned proforma. RESULTS A total of seven cases of ETMR were registered from 2015 to 2019 with a median age at presentation of four years (range 3-7 years). All patients underwent surgery. However, only three patients completed the planned adjuvant treatment, comprising of focal radiotherapy (RT) alone, craniospinal irradiation (CSI) alone and CSI followed by six cycles of chemotherapy in one patient each respectively. Two patients commenced CSI but deteriorated during RT and thereafter needed best supportive care. Two patients could not be started on any adjuvant treatment. Unfortunately, six patients succumbed to their disease within one year of their diagnosis. Only one patient who received both CSI and adjuvant chemotherapy is alive at 15 months of diagnosis. CONCLUSION ETMR is a rare and aggressive entity. Majority of the patients die within one year of the diagnosis despite multimodality treatment.

Abstract
BACKGROUND Since its discovery in Wuhan, China in December of 2019, the novel coronavirus has progressed to become one of the worst pandemics seen in the last 100 years. Recently, there has been an increased interest in the hepatic manifestations of coronavirus disease 19 (COVID-19).
AIM To describe the demographic and clinical characteristics of COVID-19 positive patients and study the association between transaminitis and all-cause mortality.
METHODS This is a descriptive retrospective cohort study of 130 consecutive patients with a positive COVID PCR test admitted between March 16, 2020 to May 14, 2020 at a tertiary care University-based medical center. The Wilcoxon-rank sum test and paired t-test were used for comparing non-parametric and parametric continuous variables respectively and a multivariable logistic regression models to study the association between transaminitis and mortality using SAS version 9.4 (SAS Institute, Cary, NC, United States).
RESULTS Out of the 130 patients, 73 (56%) patients were found to have transaminitis and 57 (44%) did not. When compared to patients without transaminitis, the transaminitis group was found to have a higher median body mass index (30.2 kg/m2vs 27.3 kg/m2, P = 0.04). In the multivariate analysis those with transaminitis were found to have 3.4 times higher odds of dying as compared to those without transaminitis adjusting for gender, the Age-adjusted Charlson Comorbidity Index and admission to the intensive care unit (P = 0.03).
CONCLUSION Our study showed that transaminitis on admission was associated with severe clinical outcomes such as admission to the intensive care unit, need for mechanical ventilation, and mortality.

Abstract
We describe the case of a 67-year-old asymptomatic man who was referred to our hospital for abnormal laboratory results. He was incidentally found to have a massive empyema without underlying bronchopulmonary pneumonia. Following thoracentesis, he was diagnosed with chronic Streptococcus anginosus empyema. Therapeutic thoracentesis and treatment with tissue plasminogen activator and deoxyribonuclease failed to resolve the empyema, and there was residual loculated pleural fluid that was surrounded by a thick rind. The patient was referred to thoracic surgery for decortication of the pleural space via video-assisted thoracoscopic surgery. At 2-month follow-up, the patient had complete re-expansion of the lung tissue.

Abstract
Plant genetic resources (PGR) are the foundation of agriculture as well as food and nutritional security.
The ICAR-NBPGR is the nodal institution at national level for management of PGR in India under the umbrella
of Indian Council of Agricultural Research (ICAR), New Delhi. India being one of the gene-rich countries faces a
unique challenge of protecting its natural heritage while evolving mutually beneficial strategies for germplasm
exchange with other countries. The Bureaus activities include PGR exploration, collection, exchange, characterization,
evaluation, conservation and documentation. It also has the responsibility to carry out quarantine of
all imported PGR including transgenics meant for research purposes. The multifarious activities are carried out
from ICAR-NBPGR headquarters and its 10 regional stations located in different agro-climatic zones of India. It
has linkages with international organizations of the Consultative Group on International Agricultural Research
(CGIAR) and national crop-based institutes to accomplish its mandated activities. NBPGR collects and acquires
germplasm from various sources, conserves it in the Genebank, characterizes and evaluates it for different traits
and provides ready material for breeders to develop varieties for farmers. ICAR-NBPGR encompasses the National
Genebank Network and at present, the National Genebank conserves more than 0.40 million accessions. NBPGR
works in service-mode for effective utilization of PGR in crop improvement programmes which depends mainly
on its systematic characterization and evaluation, and identification of potentially useful germplasm. NBPGR is
responsible for identifying trait-specific pre-adapted climate resilient genotypes, promising material with disease
resistance and quality traits which the breeders use for various crop improvement programmes. The system has
contributed immensely towards safeguarding the indigenous and introducing useful exotic PGR for enhancing
the agricultural production. Presently, our focus is on characterization of ex situ conserved germplasm and
detailed evaluation of prioritized crops for enhanced utilization; assessment of impact of on-farm conservation
practices on genetic diversity; genome-wide association mapping for identification of novel genes and alleles for
enhanced utilization of PGR; identification and deployment of germplasm/landraces using climate analog data;
validation of trait-specific introduced germplasm for enhanced utilization.
Key words: plant genetic resources; gene banks; wild relatives; biotic and abiotic stresses; marker-assisted
selection.
