Neck circumference in polycystic ovary syndrome: a systematic review and bootstrapped meta-analysis with GRADE approach.

INTRODUCTION: Our aim was to perform a systematic review and meta-analysis for the association of neck circumference (NC) in polycystic ovary syndrome (PCOS) patients as compared to non-PCOS controls. METHODS: Primarily the PubMed/MEDLINE database, and others such as SCOPUS, Google Scholar, Cochrane Library, up to November 15, 2023 for observational studies comparing NC in PCOS versus non-PCOS women. The mean and SD values of NC and other covariates in PCOS and control groups were extracted by two independent reviewers, and the quality and risk of bias assessment was done using Newcastle-Ottawa Scale of the studies. The meta-analysis employed combined standardized mean differences (SMD) with 95% confidence intervals (CI) to compare NC between PCOS patients and controls. The heterogeneity and validity were addressed by sub-group, meta-regression, and sensitivity analyses. We conducted a Bootstrapped meta-analysis using 1000 and 10000 simulations to test the accuracy of the obtained results. The certainty of evidence was assessed by GRADE approach. RESULTS: Our meta-analysis included 9 observational studies. The PCOS patients showed a significantly higher NC values than the non-PCOS controls (SMD 0.66, 95% CI 0.41-0.91, p<0.0001). In the bootstrap meta-analysis, the accuracy of the observed findings was proved (SMD=0.66, CI=0.42 to 0.91) for the NC outcome. No publication bias was detected in the funnel plot analysis using Begg's and Egger's tests. The 95% prediction interval of 0.036 to 1.28, suggest that the true outcomes of the studies are generally in the same direction as the estimated average outcome. The sensitivity analysis provided the robustness of the outcome, and no single study was overly influential on the pooled estimate. CONCLUSION: This meta-analysis provides accurate evidence for significantly higher NC in PCOS as compared to non-PCOS controls. There is no sufficient evidence on the diagnostic accuracy measures for NC in PCOS. Hence, further research on its diagnostic utility in PCOS is needed.

Barriers, Facilitators of Iron and Folic Acid Supplementation, and Deworming Program among School-Going Adolescents of Deoghar, Jharkhand, India: A Mixed-Methods Study.

Background: This study aimed to identify barriers and facilitators of iron and folic acid supplementation and deworming programs among school-going adolescents. Methods: A mixed-method observational study was conducted among adolescents in the 8th to 10th standards and their teachers across four schools in Deoghar, Jharkhand, India, using simple random sampling. The study included a questionnaire on socio-demographics, knowledge (34 items) (α=0.894), attitudes (2 items) (α=0.711) toward iron deficiency anemia, awareness of the Weekly Iron and Folic Acid Supplementation (WIFS) program and deworming (20 items) (α=0.783), and practices related to iron folic acid supplementation (IFS) and deworming, along with qualitative components. Data were analyzed using jamovi. Results: Compliance rates for IFS and deworming were 27.5% and 67.9%, respectively. The multivariable logistic regression analysis showed that sex, religion, caste, father's educational status, per capita monthly family income (PCMI), diet type, adequate knowledge, and positive attitude toward anemia influenced IFS compliance. Religion, PCMI, and prior information on the importance of deworming facilitate compliance. Implementation barriers included irregular medication supply and a lack of student awareness. Conclusion: Periodic evaluation, regular sensitization, and a consistent drug supply are necessary to effectively implement WIFS and deworming programs in the study area.

Effectiveness of Stem Cell Therapy for Diabetic Foot Ulcers: A Systematic Review and GRADE Compliant Bootstrapped Meta-Analysis of Randomized Clinical Trials.

Diabetic foot (DF) represents a severe complication of diabetes mellitus, imposing substantial psychological and economic burdens on affected individuals. This investigation sought to assess the therapeutic efficacy of stem cell interventions in the management of DF complications. A comprehensive systematic search across PubMed, Embase, CINAHL, Scopus, and the Cochrane library databases was conducted to identify pertinent studies for meta-analysis. Outcome measures encompassed ulcer or wound healing rates, amputation rates, angiogenesis, ankle-brachial index (ABI), and pain-free walking distance. Dichotomous outcomes were expressed as risk differences (RDs) with 95% confidence intervals (CIs), while continuous data were articulated as standardized mean differences (SMDs) with corresponding 95% CIs. Statistical analyses were executed using RevMan 5.3 and Open Meta, with bootstrapped meta-analysis conducted through OpenMEE software. A total of 20 studies, comprising 24 arms and involving 1304 participants, were incorporated into the meta-analysis. The findings revealed that stem cell therapy exhibited superior efficacy compared to conventional interventions in terms of ulcer or wound healing rate [RD = 0.36 (0.28, 0.43)], pain-free walking distance [SMD = 1.27 (0.89, 1.65)], ABI [SMD = 0.61 (0.33, 0.88)], and new vessel development [RD = 0.48 (0.23, 0.78)], while concurrently reducing the amputation rate significantly [RD = -0.19 (-0.25, -0.12)]. Furthermore, no statistically significant difference in adverse events was observed [RD -0.07 (-0.16, 0.02)]. The Grading of Recommendations, Assessment, Development, and Evaluation assessment indicated varying levels of evidence certainty, ranging from very low to moderate, for different outcomes. Bootstrapping analysis substantiated the precision of the results. The meta-analysis underscores the significant superiority of stem cell therapy over conventional approaches in treating DF complications. Future investigations should prioritize large-scale, randomized, double-blind, placebo-controlled, multicenter trials, incorporating rigorous long-term follow-up protocols. These studies are essential for elucidating the optimal cell types and therapeutic parameters that contribute to the most effective treatment strategies for DF management.

Nucleobindin-2 derived nesfatin-1 in polycystic ovary syndrome: a PRISMA and GRADE-compliant systematic review and meta-analysis with diagnostic test accuracy.

INTRODUCTION: Nesfatin-1 is a satiety peptide secreted by central, peripheral nervous system and some peripheral tissues. This meta-analysis was conducted to explore the associations with diagnostic accuracy of circulatory nesfatin-1 in polycystic ovary syndrome (PCOS). EVIDENCE ACQUISITION: Relevant studies were retrieved by online database and manual searching. The standardized mean differences (SMDs) with 95% confidence intervals (CIs) were obtained by a random-effects meta-analysis. The subgroup analysis based on the Body Mass Index (BMI), fasting insulin (F-INS), and the homeostasis model assessment-estimated insulin resistance (HOMA-IR) was conducted. Meta-analysis of correlations and meta-regression were performed for the associations of nesfatin-1 with metabolic and hormonal covariates. The diagnostic test accuracy (DTA) meta-analysis was conducted for the utility of nesfatin-1 in PCOS. The publication bias was tested with Egger's and Begg's regression tests. EVIDENCE SYNTHESIS: The combined effect size including a total of 14 studies showed a significantly higher nesfatin-1 level in PCOS as compared to controls (SMD=0.93, Z=2.17, P=0.03). The nesfatin-1 was found to be significantly higher in a subgroup of studies with mean BMI>25 kg/m2 (SMD=1.35, Z=2.06, P=0.04), F-INS <13 mIU/mL (SMD=2.74, Z=3.59, P=0.0003), and HOMA-IR >2.7 (SMD=1.58, Z=2.65, P=0.008). The DTA meta-analysis produced a pooled diagnostic odds ratio of 19.58 and area under curve were of 0.888 for nesfatin-1 in PCOS. CONCLUSIONS: The results indicate a multifactorial involvement such as endocrine and metabolic alterations in the form of BMI, insulin and HOMA-IR status with the higher nesfatin-1 levels in PCOS. The promising results of DTA meta-analysis warrants further research into the clinical and prognostic utility of nesfatin-1 in PCOS.

Prevention of "bygone futures" due to road traffic injuries in children.

Road traffic injuries remain one of the common and leading causes of death among children and adolescents till the age of 19 years. Road safety is important for children since their physical activity, active travel, independence and development are largely affected by it. Solutions for road safety with benefits for people as well as an economy exist which should be implemented effectively and efficiently. These solutions which combine engineering, legislation and behavioural interventions should be implemented in an integrated Safe Systems Approach. The future of the children must be safeguarded from these injuries and every effort towards it being converted into "bygone figures" must be done diligently and honestly. The various risk factors and interventions possibly explained in this review article shall help in better understanding of the causes and possible guidelines at a policy level to prevent road traffic injuries in children.

Self-Reported Persistent Symptoms at 18 Months and Above Among COVID-19 Non-hospitalized Patients: A Prospective Cohort Study.

INTRODUCTION: Since the beginning of the pandemic in early 2020, there have been numerous reports of symptoms that have lingered due to COVID-19. However, there is a lack of data concerning these persistent symptoms in non-hospitalized patients. This study sought to examine the prevalence of persistent symptoms at 18 months and beyond following the diagnosis of COVID-19 non-hospitalized patients. METHODS: A prospective cohort study comprised 212 non-hospitalized adult patients consecutively assessed from data available at tertiary care institutions through telephone interviews. During the interview, participants were routinely questioned about whether they were still experiencing any post-infection symptoms at the time of the study. RESULTS: Total 212 took part in the 18-month or longer follow-up survey. The most commonly reported symptoms during the acute phase were fever (n=149, 70.3%), weakness (n=118, 55.7%), and sore throat (n=100, 47.2%). At the 18-month and above follow-up, 167 patients (78.7%) reported at least one symptom continuing. The most common symptom at this time point was fatigue (n=109, 51.4%), followed by joint pain (n=57, 26.8%), and exertional dyspnea (24.5%). The possibility of symptoms returning after an 18-month follow-up and beyond was significantly lower in patients who had taken the COVID-19 vaccine (OR=0.29; 95% CI: 0.112-0.749; p=0.011) and those did not infect a second time (OR=0.232; 95% CI: 0.057-0.93; p=0.04). CONCLUSION: The present study reveals that clinical complications persist even at 18 months and beyond during follow-up, with a prevalence similar to earlier follow-up periods, regardless of the severity of the initial COVID-19 infection.

"Taste modification" strategy for prevention and control of hypertension in India: need for robust clinical trials.

Hypertension is an important modifiable risk factor for cardiovascular disease (CVD). Among normotensives, excessive dietary salt elevates the blood pressure and thereby increases the risk of CVD events. Despite such solid evidence, there is no effective approach to address excessive salt intake in India. Instead of just encouraging patients to lower their salt intake, we must provide an alternative technique by fostering an environment that facilitates this behaviour change. In this Viewpoint, we propose 'Taste Modification' strategy, i.e., a salt-reduction technique in which individuals are informed that adding spices/herbs to meals will reduce their salt intake. We hypothesise that a gradual reduction in salt intake can aid in the treatment of hypertension over time. The goal is to progressively substitute salt with spices for effective salt reduction. However, the 'Taste Modification' strategy must be first validated using multicentric clinical trials.

Effect of Electromagnetic Radiation from Mobile Phones on Auditory Brainstem Response.

Mobile phones are being used by around 70% of the global population. A simple non-invasive procedure to detect early impairment of the acoustic nerve and auditory pathway is by auditory brainstem response (ABR). It's a response to the sound stimulus generated from the brainstem in the form of electrical impulses. To determine the effect of long-term usage of mobile phones on auditory brainstem responses (ABRs). This Epidemiological, cross-sectional study was undertaken at a tertiary care hospital and includes 865 individuals aged between 18 to 45 years using mobile phone for > 2 years. Users were categorized into various groups according to the minutes of mobile usage per day, years of mobile usage and total duration of mobile phone use in dominant (mobile using) and non-Dominant (non-mobile using) ears. The changes in ABR were studied in each ear to ascertain the effect of EMF exposure due to chronic mobile phone use. Mean age of subjects was 27.01 years. (M: F = 1.57:1.0). Range of mobile phone usage was from 4 to 900 min/day, with mean as 85.94 min/day. No significant differences were seen between dominant and non-dominant ears in regard to amplitudes of wave I, III and V, latencies of wave I and V and Inter peak latency (IPL) of wave I-III, III-V and I-V. No statistically significant difference for I-III, III-V and I-V IPL were found b/w two groups/ears except for usage of mobile phone for > 180 min/day in wave I-V, usage for 0-4 years in wave I-III and I-V and net hours usage for > 1500 h in wave I-V. The mean IPL in all the waves increases with the increase in years of mobile usage and is maximum in all waves in > 12 years mobile users. The long-term exposure to EMF does induce measurable changes in ABRs. Amplitude and IPLs of ABR were found comparable between the dominant and non-dominant ears using mobile phones, except for those using mobile usage for > 180 min/day and with increasing years of usage of mobile phone. Therefore, prudent use of mobile phone should be encouraged for a shorter period of time and for essential purpose only.

Pooled Prevalence of Long COVID-19 Symptoms at 12 Months and Above Follow-Up Period: A Systematic Review and Meta-Analysis.

Current data suggests that coronavirus disease 2019 (COVID-19) survivors experience long-lasting problems. It is not yet understood how long these symptoms last. The goal of this study was to compile all the data that was currently available to evaluate COVID-19's long-term effects at 12 months and above. We looked for studies published by December 15, 2022, in PubMed and Embase that discussed follow-up findings for COVID-19 survivors who had been alive for at least a year. A random-effect model was carried out to determine the combined prevalence of different long-COVID symptoms. The Joanna Briggs Institute tool was used to assess the risk of bias for the included studies, and the I2 statistics were used to evaluate the heterogeneity. After reviewing 3,209 studies, 46 were deemed admissible, with an aggregate COVID-19 population of 17976. At 12 months and above, 57% of patients reported a minimum of one symptom, and the five most prevalent symptoms were: dyspnea on exertion (34%, 95% CI 0.2; 0.94); difficulty in concentration (32%, 95% CI 0.16; 0.52); fatigue (31%, 95% CI 0.22; 0.40); frailty (31%, 95% CI 0.06; 0.78); and arthromyalgia (28%, 95% CI 0.09; 0.6). The findings of the present study showed that at 12 months and beyond, a sizable fraction of COVID-19 survivors still have lasting symptoms that impair several body systems. Long-COVID patients require an urgent understanding of pathophysiological processes and the development of tailored treatments.

Cross-Sectional Analysis of Videonystagmography (VNG) Findings in Balance Disorders.

OBJECTIVE: To understand the videonystagmography (VNG) findings in various balance disorders in 67 patients who presented to the outpatient department of an otorhinolaryngology clinic. MATERIALS AND METHODS: This cross-sectional study was conducted in the outpatient department of the otorhinolaryngology clinic of a tertiary care center. A total of 67 patients between the age group of 18 and 70 years with balance disorders were included in the study. VNG findings in different balance disorders were observed and analyzed. RESULTS: A total of 67 patients were enrolled in the study. Findings like caloric inversion and optokinetic nystagmus do not always indicate a central balance disorder due to technical errors and other limitations during the test. However, abnormal saccades seem to be a more relevant finding in central disorders. Rare variants of benign paroxysmal positional vertigo (BPPV) like multiple canal BPPV were also diagnosed using VNG. CONCLUSION: VNG has come out as a very useful test in our study aiding in 75% of diagnoses. The overall benefits of VNG in balance disorders are immense and necessitate their inclusion in every vertigo clinic.

Inventory Control Mechanism of the Pharmacy Store of a Recently Established National Institute in Eastern India: A Cross-Sectional, Investigative Analysis.

Background New establishments frequently face challenges. Pharmacy is integral to healthcare delivery institutes, and inventory management is crucial. The present study investigated the problems faced by the pharmacy of a newly established health institute and proposed relevant solutions to identify drugs needing stringent management control. Methods Responses were collected from seven pharmacists for questionnaires focusing on pharmacy problems and possible solutions. Always better control (ABC), vital essential desirable (VED), and ABC-VED matrix analysis were done on the drugs dispensed during the financial 2022-23. Results The predominant challenges identified were stockouts and shortages, expiry of medications, and supplier-related issues. The causes were mainly related to rural location, communication hurdles, and vendor management. Proposed solutions were integrating patients' electronic health records and bar code technology with the pharmacy's inventory management system, conducting pharmacy knowledge and skills upgradation sessions every six months, adopting ABC and VED analysis, and first-in first-out (FIFO), just-in-time (JIT). Total annual drug expenditure (ADE) for the drugs dispensed was 1,18,81,520 Indian Rupees. ABC analysis revealed 109 (22.8%), 115 (24.06%), and 254 (53.14%) of medicines as A, B, and C categories, respectively, accounting for 69.98, 20.00, and 10.07% of ADE. On ABC-VED matrix analysis, 125 (26.15%), 267 (55.86%), and 86 (17.99%) of drugs were found to be category I, II, and III items, respectively, accounting for 71.52, 23.84, and 4.64% of ADE. Conclusion Our study identified different pharmacy problems for a developing institute and suggested relevant measures. Categorization of drugs based on ABC and VED analysis will help to strengthen inventory control.

Patients' Satisfaction on Telemedicine Service in Relation to COVID-19 and Non-COVID-19 Problems: A Cross-Sectional Comparative Study.

BACKGROUND: Telemedicine service was historically started for ambulatory and hospice care patients. Since 2020, we have been in the midst of the COVID-19 pandemic. The availability of healthcare facilities became limited due to repeated locked down during the COVID-19 pandemic. Thus, telemedicine service has gained tremendous popularity among healthcare services. Telemedicine service was started at All India Institute of Medical Sciences (AIIMS), Deoghar, as a COVID Helpline facility to provide guidance and care to the home isolated COVID-19 patients during the second wave of COVID-19. But we observed that more than 40% of calls were due to non-COVID-19-related problems, but we managed the non-COVID-19-related calls by discussing with a specialist in conference calls or WhatsApp consultation. Therefore, we planned to compare individual satisfaction with telemedicine services in patients with COVID-19 and non-COVID-19-related problems. METHODS AND MATERIALS: This study was a cross-sectional retrospective analysis of the register of telemedicine maintained in AIIMS, Deoghar, callers were grouped into two- COVID-19 and non-COVID-19-related problems. We obtained feedback from the patients and recorded it in a google form, collected data were analyzed in both groups. Telephonic consent was taken for participating in the study. The sample size was calculated to be 252, the COVID-19 group: 126, and the non-COVID-19 group: 126, and simple random sampling was used to choose the participants from the 730 total callers of the first month of telemedicine service. Their response was graded on 4 points Likert scale (1=Poor, 2=fair, 3=Good, 4=Excellent) and outcomes were analyzed by IBM SPSS (version 20.0) software. A p-value of <0.05 was considered statistically significant. OBJECTIVE: The primary objective is to estimate the level of satisfaction in both groups and compare their level of satisfaction. The secondary objective is to determine the department-specific telemedicine services requirement for people in need. RESULTS: Out of a total of 252 patients, most (54%) callers were 18-45 years old, and 44% were above 45 years old. 64% of patients were male. 90% of callers were from urban or semi-urban districts. 90% of callers had a 10th-grade or more education. 89% of patients were willing to use telemedicine services in the future. An Independent sample t-test was used to compare the means of both the groups showed a significant difference (p < 0.05) in the level of satisfaction in the COVID-19 group to the non-COVID-19 group. It showed that satisfaction in the COVID-19 group was higher than the group with non-COVID-19-related problems. CONCLUSION: COVID-19 has changed the whole spectrum of healthcare needs of the community. Our study findings showed that there is a need for separate department-wise telemedicine services to provide satisfactory service for attending to problems related to that department. For example, problems with diabetes should be attended to by an endocrinologist or an internal medicine specialist. This study finding helped us to change the policy and start department-wise telemedicine service.

Feasibility and Acceptability of Teleconsultation During COVID-19: A Cross-Sectional Study.

Background The coronavirus disease 2019 (COVID-19) pandemic created an aberrant challenge for healthcare delivery systems, forcing public health policies across the globe to be shifted from traditional medical care in hospitals to virtual care in the homes of patients. To tackle this pandemic, telemedicine had taken center stage. This study aims to learn about patient satisfaction, feasibility, and acceptability of the use of telemedicine for clinical encounters during the COVID-19 pandemic. Methodology This single-center, cross-sectional, observational study was done on a total of 758 patients who were provided with teleconsultations during the COVID-19 pandemic. We developed a 49-item questionnaire consisting of patients' quality of consultation and patients' expectations to evaluate the feasibility, acceptability, and patient satisfaction with their telemedicine consultations. Results The majority of survey participants (97.1%) expressed satisfaction with the quality of the consultations provided through telemedicine. A large percentage of participants (96.8%) reported the benefits of teleconsultation in treating their problems. Overall, 93.3% of participants responded positively to the continuation of teleconsultation services after the pandemic. Conclusions The study revealed a wide extent of satisfaction among patients. The feasibility and acceptability of telemedicine services have transformed the mode of healthcare delivery systems.

Microscopic Parotidectomy: A Prospective Study.

To assess the parameters' setting of the microscope during parotidectomy and the impact of microscopic parotidectomy on facial nerve functional status. A prospective study was conducted on 28 patients in a tertiary care center, who underwent microscopic parotidectomy. Microscope's settings' like magnification, focal length, diameter of the visualized field, and clock position were recorded. Facial nerve functional status was also recorded. All surgeries were performed by right-handed surgeons using Leica F 20 M525 microscope. Clock position of microscope for right parotidectomy ranged between 7 and 10 o clock and for left, it ranged between 7 and 12 o clock. Magnification ranged between 1.3 × and 3.2 ×; magnifications of 1.3 × and 1.8 × were preferred from incision to separation of parotid from sternocleidomastoid muscle, 1.8 × and 2 × for dissection of the facial nerve trunk, and 2 × and 3.2 × for individual branches of the facial nerve. Focal length ranged between 251 and 410 mm and the diameter of the visualized field ranged between 7 and 14.7 cm. Out of 24 cases of benign lesions, 2 (8.3%) developed facial paresis which resolved in 3 months. Two out of four cases of malignancy developed permanent palsy as nerve branches were sacrificed to achieve tumor clearance. Using a microscope for parotidectomy is advantageous for facial nerve dissection, reducing chances of facial paralysis. The microscope was also found to be useful for teaching. The use of appropriate microscopic parameters avoids the glitch of transition from open to microscopic approach.

Novel Modifications to Total Maxillary Swing Approach in Extensive Nasopharyngeal Angiofibroma to Minimize Complications.

Maxillary swing approaches provide excellent exposure of the anterior, mid, and anterolateral skull base offering a wide window to approach nasopharyngeal neoplasms; however, they are also associated with complications. The present study aimed to evaluate the results of a modified total maxillary swing (TMS) approach developed to minimize postoperative complications. The modified TMS approach was used to treat five patients who had extensive juvenile nasopharyngeal angiofibromas between March and October 2019 at our tertiary care center. Surgical technique, preoperative image findings, and intra-operative findings were recorded. In the postoperative follow-up, patients were examined to rule out all possible complications associated with the procedure according to the literature. A retrospective analysis was performed to assess tumor extensions, surgical modifications, and postoperative complications. All tumors had orbital and infratemporal (lateral limit) involvement while four had intracranial involvement. No per-operative complications were reported, and postoperative clinical and endoscopic evaluation was performed at 1, 2, and 3 months. There was no evidence of complications including residue, recurrence, maxillary necrosis, ophthalmoplegia, epiphora, palatal fistula, or jaw malocclusion. Besides, minor complications such as infraorbital margin skin retraction, infraorbital serous collection, maxillo-zygomatic abscess, and unsightly scar were also not seen. Only one case presented with maxillary osteomyelitis which was resolved with mini-plate removal and antibiotics. A modified TMS approach is a prudent option to ensure complete removal of juvenile nasopharyngeal angiofibromas with negligible complications.

Supernumerary Tooth: Endoscopic Removal for a Rare Cause of Recurrent Epistaxis.

The presence of ectopic (supernumerary) teeth is common odontogenic problem in clinical practice. Its presence in dentate region is common but rare in the non dentate areas such as nose and maxillary sinus. The intranasal teeth generally remain asymptomatic but can get misdiagnosed for foreign body, or may present as complications like headache, epistaxis, nasal obstruction, rhinolith formation, oroantral fistula and sinusitis. Here, we discuss a case of intranasal tooth as a rare cause of profuse and recurrent epistaxis. The clinical, radiological findings and surgical treatment via endoscopic approach of this rare entity has been discussed. This interesting case report highlights the need to look beyond nose as cause for epistaxis. Endoscopic removal for this entity can be a preferred option to help minimize complications.

First Report on Concomitant Infection of Nasal Myiasis and Trichosporonosis in an Uncontrolled Diabetic Patient: Case Report.

Myiasis is an infestation of living tissue of animals or humans by fly larvae. It is quite common in tropical countries due to hot and humid climates. Trichosporonosis is an invasive disseminated fungal infection caused by Trichosporon species. Disseminated trichosporonosis is usually a fatal disease with poor prognosis. The aim of this manuscript is to report a clinical case of concomitant nasal myiasis and Trichosporonosis infection in an uncontrolled diabetic patient which was treated successfully by two weeks of Voriconazole therapy.
