In them, we can find the values of the frequencies, amplitudes, phases, corresponding errors, and S/N of the extracted peaks., In this work, we aim at constraining the age of the young open cluster Melotte 20, known as α Per, using seismic indices. The method consists of the following steps: (1) Extract the frequency content of a sample of stars in the field of an open cluster. (2) Search for possible regularities in the frequency spectra of δ Sct stars candidates, using different techniques, such as the Fourier transform, the autocorrelation function, the histogram of frequency differences and the échelle diagram. (3) Constrain the age of the selected stars by both the physical parameters and seismic indices by comparing them with a grid of asteroseismic models representative of δ Sct stars. (4) Find possible common ages between these stars to determine the age of the cluster. We performed the pulsation analysis with MultiModes, a rapid, accurate and powerful open-source code, which is presented in this paper. The result is that the age of α Per could be between 96 and 100 Myr. This is an improvement over different techniques in the past. We therefore show that space astroseismology is capable of taking important steps in the dating of young open clusters., Project 'Contribution of the UGR MCNI/AEI/PID2019-107061GB-C64, Spanish public funds for research PID2019-107061GB-C64, Spanish Ministry of Science and Education, European Regional Development Fund/Junta de Andalucia-Consejeria de Economia y Conocimiento' E-FQM-041-UGR18, Universidad de Granada, Spanish public funds for research from project PID2019-107061GB-C63, Programas Estatales de Generacion de Conocimiento y Fortalecimiento Cientifico y Tecnologico del Sistema de I+D+i y de I+D + i Orientada a los Retos de la Sociedad', State Agency for Research of the Spanish MCIU through the `Center of Excellence Severo Ochoa' award SEV-2017-0709, PID2019-107061GB-C64, PID2019-107061GB-C61, National Aeronautics & Space Administration (NASA), Association of Universities for Research in Astronomy, Inc., under NASA NAS 5-26555

Background For addressing antibiotic overuse, Japan designed a health care policy in which eligible medical facilities could claim a financial reward when antibiotics were not prescribed for early-stage respiratory and gastrointestinal infections. The policy was introduced in a pilot manner in paediatric clinics in April 2018. Methods We conducted a quasi-experimental, propensity score-matched, difference-in-differences (DID) design to determine whether the nationwide financial incentives for appropriate non-prescribing of antibiotics as antimicrobial stewardship [800 JPY (≈7.3 US D) per case] were associated with changes in prescription patterns, including antibiotics, and health care use in routine paediatric health care settings at a national level. Data consisted of 9 253 261 cases of infectious diseases in 553 138 patients treated at 10 180 eligible or ineligible facilities. Results A total of 2959 eligible facilities claimed 316 770 cases for financial incentives and earned 253 million JPY (≈2.29 million USD). Compared with ineligible facilities, the introduction of financial incentives in the eligible facilities was associated with an excess reduction in antibiotic prescriptions [DID estimate, -228.6 days of therapy (DOTs) per 1000 cases (95% CI, -272.4 to -184.9), which corresponded to a relative reduction of 17.8% (95% CI, 14.8 to 20.7)]. The introduction was also associated with excess reductions in drugs for respiratory symptoms [DID estimates, -256.9 DOTs per 1000 cases (95% CI, -379.3 to -134.5)] and antihistamines [DID estimate, -198.5 DOTs per 1000 cases (95% CI, -282.1 to -114.9)]. There was no excess in out-of-hour visits [DID estimate, -4.43 events per 1000 cases (95% CI, -12.8 to 3.97)] or hospitalizations [DID estimate, -0.08 events per 1000 cases (95% CI, -0.48 to 0.31)]. Conclusions Our findings suggest that financial incentives to medical facilities for not prescribing antibiotics were associated with reductions in prescriptions for antibiotics without adverse health care consequences. Japan’s new health policy provided us with policy options for immediately reducing inappropriate antibiotic prescriptions by relatively small financial incentives.

Clinical guidelines recommend the development of ST-elevation myocardial infarction (STEMI) networks at community, regional and/or national level to ideally offer primary coronary angioplasty, or at least the best available STEMI care to all patients. However, there is a discrepancy between this clinical recommendation and daily practice, with no coordinated care for STEMI patients in many regions of the world. While this can be a consequence of lack of resources, in reality it is more frequently a lack of organisational power. In this paper, the Stent - Save a Life! Initiative (www.stentsavealife.com) proposes a practical methodology to set up a STEMI network effectively in any region of the world with existing resources, and to develop the STEMI network continuously once it has been established.

Aim During the second wave of COVID-19, cases of mucormycosis were increased suddenly over a period of 3 months in Maharashtra, India. An attempt was made to study the clinical profile and risk factors associated with mucormycosis. Materials and methods A retrospective descriptive study was carried out at a tertiary hospital during May 2021–July 2021. After obtaining informed written consent from the participants, various details of all participants, such as diabetes mellitus, use of steroids in COVID-19 treatment, use of immunosuppressant drugs, oxygen therapy, use of ventilators, complications that occurred during treatment, etc., were noted. All mucormycosis patients were treated with amphotericin B and aggressive surgical treatment. Results In the present study, 74.7% of mucormycosis patients were male. 77.4% of mucormycosis patients were above 40 years of age. 6.7% of mucormycosis patients were partially vaccinated. Among risk factors, 86.6% had diabetes mellitus, 84% had COVID-19 infection, 44% had received steroids, and 54.7% had received oxygen. 80% of patients were present during and within 1 month of COVID-19 infection. 52% of patients were presented in stage III and 41.3% were presented in stage II. Despite aggressive surgical debridement along with amphotericin B, mortality was 25.33%. 5.3% of patients had brain abscesses, 8% of patients had cavernous sinus thrombosis, 4% of patients had facial nerve palsy and 1.3% of patients had meningitis. Conclusion Mucormycosis was predominantly seen in male above the age of 40 years COVID-19 infection and diabetes mellitus was common risk factor for mucormycosis.

BACKGROUND Coronary vasomotor dysfunction can be diagnosed in a large proportion of patients with angina in the presence of non-obstructive coronary artery disease (ANOCA) using comprehensive protocols for coronary vasomotor function testing. Although consensus on diagnostic criteria for endotypes of coronary vasomotor dysfunction have been published, consensus on a standardised study testing protocol is lacking. AIMS In this review we provide an overview of the variations in coronary vasomotor function testing used and discuss the practical principles and pitfalls of coronary vasomotor function testing. METHODS For the purpose of this review we assessed study protocols that evaluate coronary vasomotor response as reported in the literature. We compared these protocols regarding a number of procedural aspects and chose six examples to highlight the differences and uniqueness. RESULTS Currently, numerous protocols co-exist and vary in vascular domains tested, the manner to test these domains (e.g. pre-procedural discontinuation of medication, provocative agent, solution, infusion time, and target artery) and techniques used for measurements (e.g. doppler vs thermodilution technique). CONCLUSIONS This lack of consensus on a uniform functional testing protocol hampers both a broader clinical acceptance of the concepts of coronary vasomotor dysfunction, and the widespread adoption of such testing protocols in current clinical practice. Furthermore, the endotype of coronary vasomotor dysfunction might differ between the few specialised centres that perform coronary vasomotor function testing as a result of the use of different protocols. In this review we provide an overview of the variations in coronary vasomotor function testing used and discuss the practical principles and pitfalls of coronary vasomotor function testing.

Purpose The aim of the study was to compare the user-rated benefit of two categories of hearing aids, mainly the basic and premium categories of hearing aids. Methods A questionnaire was administered on 102 hearing aids users (47 basic and 55 premium category users) with severity of hearing loss ranging from mild to moderately severe sensorineural hearing loss. The questionnaire administered was divided into mainly seven subscales which included speech intelligibility in quiet and in noise, ease of communication, the efficiency of noise reduction, localization, quality of music perception and cost effectiveness. The effect of duration of daily usage of hearing aids on performance among these different subscales was also assessed. Results Ease of communication was rated better by premium hearing aid users, whereas the cost effectiveness was rated to be better by basic users. There was no significant difference observed between performances of basic versus premium category of hearing aids in other listening domains assessed. There was no significant difference in any of the listening domains with daily usage duration for both categories of hearing aid users. Conclusion The users of premium category devices revealed better ease of communication in daily environments, whereas performance of these devices on other listening domains remains questionable. Cost effectiveness was reported to be better by the users of basic hearing aids. A prospective and controlled paired series comparison of hearing aid performance needs to be performed to confirm these findings.

Background: Bronchiectasis patients with neutrophilic airway inflammation develop symptoms of chronic cough, sputum production, and recurrent exacerbations. Roflumilast has anti-inflammatory actions via decreased neutrophilic airway inflammation. The effectiveness of roflumilast to reduce bronchiectasis exacerbation has never been evaluated.Methods: We conducted a double-blinded, randomized, placebo-controlled trial. Our primary objective was to assess the effect of roflumilast compared with that of a placebo in reducing exacerbation rates in bronchiectasis patients. The secondary objectives were the changes in forced expiratory volume in 1 second (FEV1) and St. George’s Respiratory Questionnaire (SGRQ). Bronchiectasis patients older than 18 years who had had two exacerbations during the previous 12 months were randomly assigned to receive either 500 μg of either roflumilast or a placebo once daily for 6 months in a 1:1 ratio.Results: Forty bronchiectasis patients who had experienced exacerbations were screened. Thirty patients completed the study after 6 months of treatment: roflumilast group (n=15) and placebo group (n=15). The rates of exacerbations were 0.57 and 0.59 per patient in the roflumilast and placebo groups, respectively. Prebronchodilator FEV1 increased by 0.07 L from baseline in the roflumilast group and decreased by 0.015 L in the placebo group, but the difference was not significant. No significant differences were observed in the change of SGRQ scores between the roflumilast and placebo groups. Roflumilast had significant side effects, including loss of appetite and headache.Conclusion: Roflumilast did not significantly affect the rate of exacerbations or quality of life. However, FEV1 tended to improve more in the roflumilast group than in the placebo group.

Pulmonary hypertension (PH) is a condition of increased blood pressure in the pulmonary arteries and is diagnosed with an increased a mean pulmonary artery pressure ≥25 mm Hg. This condition may be associated with multiple clinical situations. Based on pathophysiological mechanisms, clinical presentation, hemodynamic profiles, and treatment strategies, the patients were classified into five clinical groups. Although there have been major advances in the management of PH, it is still associated with significant morbidity and mortality. The diagnosis and treatment of PH have been performed mainly by following European guidelines, even in Korea because the country lacks localized PH guidelines. European treatment guidelines do not reflect the actual status of Korea. Therefore, the European diagnosis and treatment of PH have not been tailored well to suit the needs of Korean patients with PH. To address this issue, we developed this guideline to facilitate the diagnosis and treatment of PH appropriately in Korea, a country where the consensus for the diagnosis and treatment of PH remains insufficient. This is the first edition of the guidelines for the diagnosis and treatment of PH in Korea, and it is primarily based on the ‘2015 ESC/ERS Guidelines for the diagnosis and treatment of pulmonary hypertension.’ with the acceptance and adaptation of recent publications of PH.

Background The naturally occurring male-to-female (M/F) ratio at birth is 1.05. Higher ratios found primarily in countries across Asia have been attributed to prenatal sex selection due to son preference. There is growing evidence that sex-selective practices continue following migration; however, little is known about these practices following migration to Australia. Methods In this population-based study we assessed M/F ratios at birth per mother’s country of birth for all registered births 1999–2015 in Victoria, Australia (n = 1 191 250). We also compared the M/F ratio among births to mothers born elsewhere to that of mothers born in Australia, stratified by time period and parity. Results Compared with the naturally occurring M/F ratio as well as to the M/F ratio among births to mothers born in Australia, there was an increased ratio of male births to mothers born in India, China and South-East Asia, particularly at higher parities and in more recent time periods (elevated M/F ratios ranged from 1·079 to 1·248, relative risks of male birth ranged from 1·012 to 1·084 with confidence intervals between 1·001 and 1·160 and P-values between 0·005 and 0·039). The most male-biased sex ratios were found among multiple births to Indian-born mothers, and parity of two or more births to Indian and Chinese-born mothers in 2011–15. Conclusions The male-biased sex ratios observed in this study indicate that prenatal sex selection may be continuing following migration to Australia from countries where these practices have been documented. The excess of males among multiple births raises the question as to what role assisted reproduction plays. Findings also suggest that systematic discrimination against females starts in the womb.

Context. A novel high-performance exact pair counting toolkit called Fast Correlation Function Calculator (FCFC) is presented, which is publicly available at https://github.com/cheng-zhao/FCFC. Aims. As the rapid growth of modern cosmological datasets, the evaluation of correlation functions with observational and simulation catalogues has become a challenge. High-efficiency pair counting codes are thus in great demand. Methods. We introduce different data structures and algorithms that can be used for pair counting problems, and perform comprehensive benchmarks to identify the most efficient ones for real-world cosmological applications. We then describe the three levels of parallelisms used by FCFC -- including SIMD, OpenMP, and MPI -- and run extensive tests to investigate the scalabilities. Finally, we compare the efficiency of FCFC against alternative pair counting codes. Results. The data structures and histogram update algorithms implemented in FCFC are shown to outperform alternative methods. FCFC does not benefit much from SIMD as the bottleneck of our histogram update algorithm is mostly cache latency. Nevertheless, the efficiency of FCFC scales well with the numbers of OpenMP threads and MPI processes, albeit the speedups may be degraded with over a few thousand threads in total. FCFC is found to be faster than most (if not all) other public pair counting codes for modern cosmological pair counting applications., Comment: 18 pages, 18 figures. The FCFC package is publicly available at https://github.com/cheng-zhao/FCFC

Background: Mitochondrial dysfunction is strongly associated with several kidney diseases. However, no studies have evaluated the potential renal hazards of serum mitochondria-inhibiting substance (MIS) and aryl hydrocarbon receptor ligand (AhRL) levels.Methods: We used serum level of MIS and AhRL and clinical renal outcomes from 1,511 participants of a prospective community-based cohort in Ansung. MIS was evaluated based on intracellular adenosine triphosphate (MIS-ATP) or reactive oxygen species (MIS-ROS) generation measured using cell-based assays.Results: During a mean 6.9-year follow-up, 84 participants (5.6%) developed a rapid decline in kidney function. In the lowest quartile group of MIS-ATP, patients were older and had metabolically deleterious parameters. In multivariate logistic regression analysis, higher MIS-ATP was associated with decreased odds for rapid decline: the odds ratio (OR) of 1% increase was 0.977 (95% confidence interval [CI], 0.957 to 0.998; P=0.031), while higher MIS-ROS was marginally associated with increased odds for rapid decline (OR, 1.014; 95% CI, 0.999 to 1.028; P=0.055). However, serum AhRL was not associated with the rapid decline in kidney function. In subgroup analysis, the renal hazard of MIS was particularly evident in people with hypertension and low baseline kidney function.Conclusion: Serum MIS was independently associated with a rapid decline in kidney function, while serum AhRL was not. The clinical implication of renal hazard on serum MIS requires further evaluation in future studies.

Although age-related changes in skeletal muscles are closely associated with decreases in muscle strength and functional decline, their associations with cardiometabolic diseases in the literature are inconsistent. Such inconsistency could be explained by the fact that muscle quality—which is closely associated with fatty infiltration of the muscle (i.e., myosteatosis)—is as important as muscle quantity in cardiometabolic health. However, muscle quality has been less explored compared with muscle mass. Moreover, the standard definition of myosteatosis and its assessment methods have not been established yet. Recently, some techniques using single axial computed tomography (CT) images have been introduced and utilized in many studies, as the mass and quality of abdominal muscles could be measured opportunistically on abdominal CT scans obtained during routine clinical care. Yet, the mechanisms by which myosteatosis affect metabolic and cardiovascular health remain largely unknown. In this review, we explore the recent advances in the assessment of myosteatosis and its changes associated with aging. We also review the recent literature on the clinical implication of myosteatosis by focusing on metabolic and cardiovascular diseases. Finally, we discuss the challenges and unanswered questions that need addressing to set myosteatosis as a therapeutic target for the prevention or treatment of cardiometabolic diseases.

Purpose The purpose of this study was to evaluate the validity and reliability of the Turkish version of the Nijmegen Cochlear Implant Questionnaire (Tr-NCIQ) and reveal the demographic factors contributing to the outcomes. Methods A group of 118 cochlear implant users aged between 18 and 70 years filled the Tr-NCIQ and the Turkish Hearing Handicapped Inventory for Adults (the Tr-HHI-Adult) via electronic survey. Cross-cultural adaptation of the Tr-NCIQ was performed. The reliability and validity of the questionnaire were evaluated utilizing internal consistency coefficient, split-half method, and predictive validity. Results The overall Cronbach's alpha coefficient of the scale was 0.91, and the Spearman-Brown coefficient was 0.91. A moderately significant and negative correlation was present between the basic sound perception, speech production, self-esteem, activity, and social interactions subdomain scores and the HHI-Adult scores. Patients with post-lingual onset of hearing loss had significantly better results than those with pre-lingual onset, in the advanced sound perception subdomain. In addition, bilateral cochlear implant users had better results than the unilateral and bimodal users in the speech production subdomain and then the bimodal users in the self-esteem subdomain. There was no effect of age, duration of implant use, age at implantation, and the daily usage of cochlear implant (CI) on the quality-of-life outcomes. Conclusion The Tr-NCIQ is a reliable and valid tool to evaluate the subjective quality of life in CI users. In addition, as a standardized instrument, it can be easily self-administered both in clinical practice and for research purposes.

Background: Because the etiologies of bronchiectasis and related diseases vary significantly among different regions and ethnicities, this study aimed to develop a diagnostic bundle for bronchiectasis in South Korea.Methods: A modified Delphi method was used to develop expert consensus statements on a diagnostic bundle for bronchiectasis in South Korea. Initial statements proposed by a core panel, based on international bronchiectasis guidelines, were discussed in an online meeting and two email surveys by a panel of experts (≥70% agreement).Results: The study involved 21 expert participants, and 30 statements regarding a diagnostic bundle for bronchiectasis were classified as recommended, conditional, or not recommended. The consensus statements of the expert panel were as follows: A standardized diagnostic bundle is useful in clinical practice; diagnostic tests for specific diseases, including immunodeficiency and allergic bronchopulmonary aspergillosis, are necessary when clinically suspected; initial diagnostic tests, including sputum microbiology and spirometry, are essential in all patients with bronchiectasis, and patients suspected with rare causes such as primary ciliary dyskinesia should be referred to specialized centers.Conclusion: Based on this Delphi survey, expert consensus statements were generated including specific diagnostic, laboratory, microbiological, and pulmonary function tests required to manage patients with bronchiectasis in South Korea.

Cough is the most common respiratory symptom that can have various causes. It is a major clinical problem that can reduce a patient’s quality of life. Thus, clinical guidelines for the treatment of cough were established in 2014 by the cough guideline committee under the Korean Academy of Tuberculosis and Respiratory Diseases. From October 2018 to July 2020, cough guidelines were revised by members of the committee based on the first guidelines. The purpose of these guidelines is to help clinicians efficiently diagnose and treat patients with cough. This article highlights the recommendations and summary of the revised Korean cough guidelines. It includes a revised algorithm for the evaluation of acute, subacute, and chronic cough. For a chronic cough, upper airway cough syndrome (UACS), cough variant asthma (CVA), and gastroesophageal reflux disease (GERD) should be considered in differential diagnoses. If UACS is suspected, first-generation antihistamines and nasal decongestants can be used empirically. In cases with CVA, inhaled corticosteroids are recommended to improve cough. In patients with suspected chronic cough due to symptomatic GERD, proton pump inhibitors are recommended. Chronic bronchitis, bronchiectasis, bronchiolitis, lung cancer, aspiration, intake of angiotensin-converting enzyme inhibitor, intake of dipeptidyl peptidase-4 inhibitor, habitual cough, psychogenic cough, interstitial lung disease, environmental and occupational factors, tuberculosis, obstructive sleep apnea, peritoneal dialysis, and unexplained cough can also be considered as causes of a chronic cough. Chronic cough due to laryngeal dysfunction syndrome has been newly added to the guidelines.

Background: Endobronchial ultrasound‒guided transbronchial needle aspiration (EBUS-TBNA) is a standard diagnostic method for mediastinal and hilar lymphadenopathy. Although rare, fatal infectious complications can occur following EBUS-TBNA. However, to date, there is a lack of effective preventive strategies to reduce these complications. We started a trial to investigate the effect of chlorhexidine mouthrinse on the prevention of microbial contamination during EBUS-TBNA.Methods: This study is a single-center, parallel-group, assessor-blinded randomized controlled trial (RCT). We will enroll 112 adult participants undergoing EBUS-TBNA using a convex probe, and randomly assign them to two groups at a 1:1 ratio. The intervention group will gargle for 1 minute with 100 mL of 0.12% chlorhexidine gluconate before EBUS-TBNA, while the control group will have no mouthrinse before the procedure. Immediately after completion of EBUS-TBNA on all targeted lesions with an aspiration needle, a needle wash sample will be taken by instilling 5 mL of sterile saline into the used needle. The primary outcome is colony forming unit (CFU) counts in aerobic cultures of the needle wash samples. Secondary outcomes are CFU counts in anaerobic cultures, fever within 24 hours after EBUS-TBNA, and infectious complications within 4 weeks after EBUS-TBNA.Conclusion: This trial was designed as the first RCT to investigate the effect of chlorhexidine mouthrinse on the prevention of microbial contamination during EBUS-TBNA. Results from this trial can provide clinical evidence for a simple, safe, and cost-effective strategy to prevent infectious complications following EBUS-TBNA (ClinicalTrials.gov ID: NCT04718922, registered on 22 January 2021).

Objectives The study purpose was to evaluate the effects of the COVID-19 pandemic on the rate and disease profile of orofacial and respiratory infections in oral and maxillofacial surgery (OMFS) and ear, nose, and throat (ENT) emergency units. Materials and methods Records of patients with orofacial or respiratory infection, or infectious symptoms, diagnosed in the OMFS or ENT Emergency Departments of the Helsinki University Hospital, Helsinki, Finland between 1st March and 30th October 2020 and the corresponding periods in 2018 and 2019 were reviewed. The main outcome variable was the occurrence of studied infections during the evaluated periods. Other study variables were age, gender, residence area, speciality, specific cause for the emergency department visit and admission to ward. Results There was a significant 37% decrease in the number of infection patients in 2020 compared to the years 2019 and 2018 (1894 vs. 2929 and 3077, respectively, p p = .013). Conclusion A significant decrease was observed in the volume of emergency department visits for orofacial and respiratory infections during the COVID-19-pandemic in 2020 compared to the non-COVID periods. Clinical relevance It seems that social distancing, facial mask wearing, and other infection prevention precautions have changed the accustomed patient profile in orofacial and respiratory infections.

Purpose Patients affected by COVID-19 are assumed to be at high risk of developing swallowing disorders. However, to our best knowledge, data on the characteristics and incidence of dysphagia associated with COVID-19 are lacking, especially in non-intubated patients. Therefore, we investigated the onset of swallowing disorders in patients with laboratory-confirmed COVID-19 infection who have not been treated with invasive ventilation, in order to evaluate how the virus affected swallowing function regardless of orotracheal intubation. Methods We evaluated 41 patients admitted to the COVID department of our Hospital when they had already passed the acute phase of the disease and were therefore asymptomatic but still positive for SARS-CoV-2 RNA by RT-PCR. We examined patients’ clinical history and performed the Volume-Viscosity Swallow Test (VVST). Each patient also answered the Swallowing Disturbance Questionnaire (SDQ). After 6 months, we performed a follow-up in patients with swallowing disorders. Results Eight of 41 patients (20%) presented with dysphagia symptoms during hospitalization and 2 of them (25%) still presented a SDQ high score and swallowing disorders with liquid consistency after 6 months. Conclusion Non-intubated patients can experience various grades of swallowing impairment that probably directly related to pulmonary respiratory function alterations and viral direct neuronal lesive activity. Although these symptoms show natural tendency to spontaneous resolution, their impact on a general physical impaired situation should not be underestimated, since it can adversely affect patients’ recovery from COVID-19 worsening health outcomes.

Background Accumulating evidence suggests that consuming coffee may lower the risk of death, but evidence regarding tea consumption in Asians is limited. We examined the association between coffee and tea consumption and mortality in Asian populations. Methods We used data from 12 prospective cohort studies including 248 050 men and 280 454 women from the Asia Cohort Consortium conducted in China, Japan, Korea and Singapore. We estimated the study-specific association of coffee, green tea and black tea consumption with mortality using Cox proportional-hazards regression models and the pooled study-specific hazard ratios (HRs) using a random-effects model. Results In total, 94 744 deaths were identified during the follow-up, which ranged from an average of 6.5 to 22.7 years. Compared with coffee non-drinkers, men and women who drank at least five cups of coffee per day had a 24% [95% confidence interval (CI) 17%, 29%] and a 28% (95% CI 19%, 37%) lower risk of all-cause mortality, respectively. Similarly, we found inverse associations for coffee consumption with cardiovascular disease (CVD)-specific and cancer-specific mortality among both men and women. Green tea consumption was associated with lower risk of mortality from all causes, CVD and other causes but not from cancer. The association of drinking green tea with CVD-specific mortality was particularly strong, with HRs (95% CIs) of 0.79 (0.68, 0.91) for men and 0.78 (0.68, 0.90) for women who drank at least five cups per day of green tea compared with non-drinkers. The association between black tea consumption and mortality was weak, with no clear trends noted across the categories of consumption. Conclusions In Asian populations, coffee consumption is associated with a lower risk of death overall and with lower risks of death from CVD and cancer. Green tea consumption is associated with lower risks of death from all causes and CVD.

Background There is an increasing need to understand what barriers are present to reduce opioid consumption in orthopedic practice. The purpose of this study was to better understand patient perceptions and understanding of opioid use after shoulder surgery. Methods Eighty-five patients who underwent shoulder surgery anonymously completed a 27-question survey adapted from the Maryland Public Opinion Survey on Opioids with additional demographics. The patients were asked about pain expectations after surgery, use of and access to opioids, opioid perceptions, and information provided regarding safe use, storage, and disposal of opioids. Results When asked about receiving information regarding opioids, only 36% of the patients reported having a conversation with their physician. When asked about appropriate use, 10% agree it is permissible to take more than the recommended dosage of prescription narcotics if they are feeling more pain than usual and 8.5% of the patients reported taking an opioid to get high multiple times in the past year. Furthermore, a majority agreed that opioids may lead to other substance abuse with 76% reporting the risk of harm to be great, and only 55% believing that opioid abuse may lead to overdose or death. Conclusions Surgeons need to be aware that most patients expect to have significant pain after shoulder surgery and expect to be given necessary and continued amounts of opioids. This highlights the need for better counseling and innovative nonopioid pain management protocols. At the institutional level, more effort needs to be made on providing adequate education and disposal mechanisms to help reduce diversion and misuse.
