Playing a musical instrument involves the repetitive use of muscles, often at their extreme range of motion. Consequently, musicians in general are at an increased risk for the development of pain syndromes related to nerve or musculoskeletal damage. Acoustic and electric guitars are among the most popular instruments in the world today, with a large population of musicians at risk of injury. This article examines the results of a survey completed by 261 professional, amateur, and student guitarists to determine the most common anatomic locations of playing-related pain and its relationship to possible etiologic factors. A survey of 15 questions was distributed to professional, amateur, and student guitarists who play the musical genres of rock/blues, jazz, and folk across the United States and Canada. The questions addressed type of guitar played, style of music performed, playing posture, picking technique, anatomic location of pain, history of formal training, presence of playing-related pain in the past 12 months, history of trauma to the affected area, and history of other nonrelated medical problems. Playing-related pain was reported by 160 (61.3%) of 261 guitarists who completed the survey. The most often reported location was the fretting hand, with 109 (41.8%) of 261 subjects reporting the presence of playing-related pain in the previous 12 months. The back and neck were the next most reported sites of playing-related pain, with 45 (17.2%) of 261 subjects reporting back pain and 39 (14.9%) of 261 subjects reporting neck pain in the previous 12 months. The results suggest that a substantial number of guitarists playing various styles of popular music are experiencing playing-related pain.

AbstractThe association between bullous pemphigoid (BP) and melanoma is yet to be investigated. We aimed to assess assess the bidirectional association between BP and melanoma and to delineate the epidemiological features of patients with both diagnoses. A population-based cohort study was performed comparing BP patients (n = 3924) with age-, sex- and ethnicity-matched control subjects (n = 19,280) with regard to incident cases of melanoma. A case–control design was additionally adopted to estimate the risk of BP in individuals with a preexisting diagnosis of melanoma. The prevalence of preexisting melanoma was higher in patients with BP than in control subjects (1.5% vs. 1.0%, respectively; P = 0.004). A history of melanoma confers a 50% increase in the risk of subsequent BP (OR 1.53; 95% CI 1.14–2.06). This risk was higher among males (OR 1.66; 95% CI 1.09–2.54) and individuals older than 80 years (OR 1.63; 95% CI 1.11–2.38), and persisted after adjustment for multiple putative confounders including PD-1/PDL-1 antagonists (adjusted OR 1.53; 95% CI 1.14–2.06). Conversely, the risk of melanoma among patients with BP was slightly elevated, but did not reach the level of statistical significance (adjusted HR 1.13; 95% CI 0.73–1.74). Patients with a dual diagnosis of BP and melanoma were older at the onset of BP and had lower body mass index. A history of melanoma is associated with a 50% increase in the incidence of subsequent BP. Physicians managing patients with both conditions should be aware of this association. Further research is warranted to reveal the underlying mechanism of these findings.

History Of

Soybean (Glycine max) farmers in the Upper Midwest region of the United States frequently experience severe yield losses due to Sclerotinia stem rot (SSR). Previous studies have revealed benefits of individual management practices on SSR. This study examined the integration of multiple control practices on the development of SSR, yield, and the economic implications of these practices. Combinations of row spacings, seeding rates, and fungicide applications were examined in multi-site field trials across the Upper Midwest from 2017-2019. These trials revealed that wide row spacing and low seeding rates individually reduced SSR levels but also reduced yields. Yields were similar across the three higher seeding rates examined. However, site-years where SSR developed showed the highest partial profits in the intermediate seeding rates. This indicates that partial profits in diseased fields were negatively impacted by high seeding rates, but this trend was not observed when SSR did not develop. Fungicides strongly reduced the development of SSR, while also increasing yields. However, there was a reduction in partial profits due to their use at a low soybean sale price, but at higher sale prices fungicide use was similar to not treating. Additionally, the production of new inoculum was predicted from disease incidence, serving as an indicator of increased risk for SSR development in future years. Overall, this study suggests the use of wide rows and low seeding rates could be useful in fields with a history of SSR, while reserving narrow rows and higher seeding rates for fields without a history of SSR.

This chapter sketches a general history of rhythm quantization as a widespread practice in popular music culture. Quantization—a sound technology that automatically maps microrhythmic fluctuations onto the nearest beat available within a predefined metric grid—challenges traditional notions of musicking as an embodied activity that is grounded in the co-presence of human agents. At the same time, it encapsulates cultural and cognitive processes that are entirely human, fitting into a broader historical shift towards chronometric precision in Western music. Questions arising from this apparent contradiction are taken up in this chapter, which situates rhythm quantization as an emergent technocultural practice, examining its attendant technologies and requisite structures of music-theoretical knowledge, as well as its reception within the context of different musical genres.

Groin Hernias

Few studies describe the relationship between obesity and groin hernias. Our objective was to investigate the correlation between body mass index (BMI) and groin hernias in a large population. Patients with the diagnosis of inguinal or femoral hernia with and without incarceration or strangulation were identified using the Kaiser Permanente Southern California regional database including 14 hospitals over a 7-year period. Patients were stratified by BMI. There were 47,950 patients with a diagnosis of a groin hernia—a prevalence of 2.28 per cent. Relative to normal BMI (20–24.9 kg/m2), lower BMI was associated with an increased risk for hernia diagnosis. With increasing BMI, the risk of incarceration or strangulation increased. Additionally, increasing age, male gender, white race, history of hernia, tobacco use history, alcohol use, and higher comorbidity index increased the chance of a groin hernia diagnosis. Complications were higher for women, patients with comorbidities, black race, and alcohol users. Our study is the largest to date correlating obesity and groin hernias in a diverse United States population. Obesity (BMI ≥ 30 kg/m2) is associated with a lower risk of groin hernia diagnosis, but an increased risk of complications. This inverse relationship may be due to limitations of physical exam in obese patients.

Traditionally the domain of consultation/ liaison psychiatry, the challenge of recognizing and then appropriately treating the psychiatric complications of general medical disorders requires thoughtful planning and attention in corrections. Medical conditions that have psychiatric symptoms represent a significant diagnostic dilemma, particularly in the correctional health setting. Over half of the inmates in the United States have symptoms of a major mental illness, but the pervasiveness of substance use disorders, the increasing prevalence of elderly inmates, and limited access to a patient’s past medical and psychiatric records all contribute to the challenge of discerning when a psychiatric presentation results from an underlying medical condition. One early study underscored this challenge, noting that 46% of the patients admitted to community psychiatric wards had an unrecognized medical illness that either caused or exacerbated their psychiatric illness. A more recent study observed that 2.8% of admissions to inpatient psychiatry were due to unrecognized medical conditions. Emergency room medical clearance of patients presenting for psychiatric admission has revealed an increased risk for such underlying medical conditions among patients with any of five characteristics: elderly, a history of substance abuse, no prior history of mental illness, lower socioeconomic status, or significant preexisting medical illnesses. This chapter examines several of these risk groups and focuses on the presenting symptoms of delirium, mood disorders, and psychosis and the underlying medical conditions that can mimic or exacerbate them.

Abstract Primary brain tumors account for ~1% of new cancer cases and ~2% of cancer deaths in the United States; however, they are the most commonly occurring solid tumors in children. These tumors are very heterogeneous and can be broadly classified into malignant and benign (or non-malignant), and specific histologies vary in frequency by age, sex, and race/ethnicity. Epidemiological studies have explored numerous potential risk factors, and thus far the only validated associations for brain tumors are ionizing radiation (which increases risk in both adults and children) and history of allergies (which decreases risk in adults). Studies of genetic risk factors have identified 32 germline variants associated with increased risk for these tumors in adults (25 in glioma, 2 in meningioma, 3 in pituitary adenoma, and 2 in primary CNS lymphoma), and further studies are currently under way for other histologic subtypes, as well as for various childhood brain tumors. While identifying risk factors for these tumors is difficult due to their rarity, many existing datasets can be leveraged for future discoveries in multi-institutional collaborations. Many institutions are continuing to develop large clinical databases including pre-diagnostic risk factor data, and developments in molecular characterization of tumor subtypes continue to allow for investigation of more refined phenotypes. Key Point 1. Brain tumors are a heterogeneous group of tumors that vary significantly in incidence by age, sex, and race/ethnicity.2. The only well-validated risk factors for brain tumors are ionizing radiation (which increases risk in adults and children) and history of allergies (which decreases risk).3. Genome-wide association studies have identified 32 histology-specific inherited genetic variants associated with increased risk of these tumors.

Background: The rate of osteoarthritis (OA) in patients with a history of previous anterior shoulder instability (ASI) varies within the literature, with the majority of studies investigating rates after surgical stabilization. ASI appears to lead to increased rates of OA, although risk factors for developing OA in cohorts treated nonoperatively and operatively are not well-defined. Purpose: To determine the incidence of clinically symptomatic OA and identify potential risk factors for the development of OA in patients younger than 40 years with a known history of ASI. Study Design: Case-control study; Level of evidence, 3. Methods: An established, geographically based database was used to identify patients in the United States who were younger than 40 years and were diagnosed with ASI between 1994 and 2014. Patient information, including demographic, imaging, and surgical details, was collected. Comparative analysis was performed between groups with and without OA at final follow-up as well as between patients who underwent surgical and nonsurgical management. Results: The study population consisted of 154 patients with a mean follow-up of 15.2 years (range, 5.1-29.8 years). The mean age at initial instability event was 20.9 years (95% CI, 19.9-22.0 years). Overall, 22.7% of patients developed clinically symptomatic glenohumeral OA. Multivariate analysis revealed that current or former smokers (odds ratio [OR], 4.3; 95% CI, 1.1-16.5; P = .030), hyperlaxity (OR, 10.1; 95% CI, 1.4-72.4; P = .020), laborer occupation (OR, 6.1; 95% CI, 1.02-36.1; P = .043), body mass index (BMI) (OR, 1.2; 95% CI, 1.03-1.3; P = .012), and age at initial instability (OR, 1.1; 95% CI, 1.02-1.2; P = .013) as potential independent risk factors when accounting for other demographic and clinical variables. Conclusion: In a US geographic population of patients younger than 40 years with ASI, approximately one-fourth of patients developed symptomatic OA at a mean follow-up of 15 years from their first instability event. When accounting for differences in patient demographic and clinical data, we noted a potentially increased risk for the development of OA in patients who are current or former smokers, have hyperlaxity, are laborers, have higher BMI, and have increased age at initial instability event. Smoking status, occupation, and BMI are modifiable factors that could potentially decrease risk for the development of symptomatic OA in these patients.

e13070 Background: In the last two decades, the incidence of colorectal cancer (CRC) has decreased dramatically after the implementation of CRC screening in the United States. Several risk factors for colonic adenoma (CA), the main precursor for CRC, have been found. Whether personal history of non-colorectal cancer (NCRC) is a risk factor for CA has not been studied. Here, we assess the risk of CA in patients with NCRCs. Methods: We conducted a retrospective study of cancer patients who underwent colonoscopy after cancer diagnosis between 2009 and 2018. We included patients without history of NCRC as a control group. Multivariate logistic regression was used to assess independent risk factors for CA (Table 1). Results: Total of 9408 patients with NCRC were included; CA was detected in 4503 (48%). Histology revealed tubulovillous features in 611 (14%) patients and villous in 51 (1%). High grade dysplasia was detected in 1,317 (29%) patients and adenocarcinoma in 388 (9%). The rate of adenocarcinoma was the highest in patients with multiple myeloma (14%). Adenoma detection rate (ADR) was 30% in patients younger than 40 years ( n= 1621), 32% in patients between 40 and 50 years ( n= 812), 47% in patients between 50 and 60 years ( n= 2892), and 55% in patients older than 60 years ( n= 4493). Multivariate analysis revealed an increased risk of CA with old age, male sex, family history of CRC, and high body mass index ( P< 0.05). The median time from NCRC diagnosis to CA detection was 3 years (IQR 1-8). Conclusions: ADR in patients with a personal history of NCRC is higher than the ADR of patients without NCRC. CRC screening should be performed after the diagnosis of NCRC is made, even if it was before the standard threshold of CRC screening age of 50 years.[Table: see text]

288 Background: Colorectal cancer (CRC) is the second most common cause of cancer deaths in the United States and expected to cause 51,020 deaths in 2019. Early detection with yearly fecal occult blood test (FOBT) has been proven to decrease CRC mortality. A 30-day delay from positive FOBT to colonoscopy is associated with increased risk of CRC. The Veterans Affairs Health System (VAHS) treats approximately 11% of CRCs in the United States. The effects of an aging population, physician shortage, and increased military personnel entering the VAHS may increase demands on VAHS resources. The primary aim of this study was to determine risk factors that caused delay to colonoscopy. Methods: We retrospectively reviewed records of 600 patients referred for colonoscopy from January 1999 to January 2009, who were subsequently diagnosed with CRC. Patients with a prior CRC diagnosis were excluded. The final study cohort consisted of 530 patients. We analyzed the relationship between 10 variables and delay in time from initial consultation to colonoscopy. Variables consisted of age, sex, race, ethnicity, CRC location, marital status, history of mental health diagnosis, tobacco use, substance abuse, Charlson/Deyo (C/D) score and season of referral for colonoscopy. A delay in time was defined as 30 days or greater. Logistic regression analysis adjusted for age, race, CRC location and C/D score. Results: A total of 87.17% of patients experienced a delay in time from initial consultation to colonoscopy. When analyzed with a predictive variable of delay to colonoscopy, C/D score of ≥ 2 versus 0, was associated with higher odds of delay in time to colonoscopy (OR = 2.18, p = 0.02). African American race and Hispanic ethnicity was associated with a higher odds of delay in time to colonoscopy, but was not statistically significant (OR = 1.47, p = 0.47, OR = 1.37, p = 0.48). Conclusions: Patients with a C/D score ≥ 2 were 218% more likely to have delay in time from initial consult to colonoscopy, resulting in a delayed CRC diagnosis. C/D score may be used to determine which patients should have more frequent reminders to schedule their colonoscopy to prevent delays in care. Randomized and prospective studies will need to be performed.
