RESUMEN
INTRODUCTION: Recent associative studies have linked intra-pancreatic fat deposition (IPFD) with risk of pancreatitis, but the causal relationship remains unclear. METHODS: Utilizing Mendelian randomization, we evaluated the causal association between genetically predicted IPFD and pancreatitis. This approach utilized genetic variants from genome-wide association studies of IPFD (n=25,617), acute pancreatitis (n=6,787 cases/361,641 controls), and chronic pancreatitis (n=3,875 cases/361,641 controls). RESULTS: Genetically predicted IPFD was significantly associated with acute pancreatitis (OR per 1-SD increase: 1.40[95%CI:1.12-1.76], p=0.0032) and chronic pancreatitis (OR:1.64[95%CI:1.13-2.39], p=0.0097). DISCUSSION: Our findings support a causal role of IPFD in pancreatitis, suggesting that reducing IPFD could lower the risk of pancreatitis.
RESUMEN
BACKGROUND: Meningitis, especially of bacterial origin, is a medical emergency that must be diagnosed promptly. However, due to the associated risks of complications of lumbar puncture, it is crucial to identify individuals who truly need it. The aim of this study was to assess the diagnostic role of inflammatory markers in distinguishing among patients without meningitis, those with aseptic meningitis, and those with bacterial meningitis. METHODS: This was a retrospective, diagnostic study at an acute care hospital, involving adult patients who presented to either ambulatory care or the emergency department with fever and headache, but without altered mental status or neurological deficits. Inflammatory markers (C-reactive protein [CRP], mean platelet volume, neutrophil-lymphocyte ratio, and red cell distribution width) were assessed as index tests. An expert panel classified patients into three groups: no meningitis, aseptic meningitis, and bacterial meningitis using predefined criteria. RESULTS: Of the 80 patients, 52 had no meningitis, 27 had aseptic meningitis, and 1 had bacterial meningitis. Of the inflammatory markers investigated, only CRP showed potential usefulness in differentiating these three diagnostic groups, with median values of 5.6 (interquartile range [IQR] 2.1, 11.3) mg/dL in those without meningitis, 0.2 (IQR 0.1, 1.2) mg/dL in those with aseptic meningitis, and notably elevated at 21.7 mg/dL in the patient with bacterial meningitis. CONCLUSION: In adult patients presenting with fever and headache in an emergency setting, CRP was the only marker that demonstrated potential diagnostic utility in distinguishing among those with no meningitis, aseptic meningitis, and bacterial meningitis.
RESUMEN
BACKGROUND: Due to potentially fatal consequences of missed bacteremia, blood cultures are often overused. While there are several prediction models that can be used to identify patients who truly need blood cultures, physicians often rely on their gestalt. We evaluated the diagnostic performance of physician gestalt for bacteremia in comparison with 2 existing prediction models: Takeshima and Shapiro. METHODS: The study enrolled consecutive adult patients with suspected infection who were in the process of being admitted to the general medicine department at 2 hospitals between April 2017 and January 2019. Attending physicians provided gestalt regarding risk of bacteremia (0%-100%). Patients with a <10% risk estimated via each strategy (ie, physician gestalt or 2 existing models) were categorized as bacteremia excluded (ie, blood cultures were considered unnecessary). Strategies were compared in terms of safety (proportion of patients with bacteremia among those classified as bacteremia excluded) and efficiency (proportion of patients classified as bacteremia excluded among the total cohort). RESULTS: Among 2014 patients, 292 (14.5%) were diagnosed with bacteremia. The safety of physician gestalt and the Takeshima and Shapiro models was 3.7% (95% confidence interval [CI], 2.2% to 5.7%), 6.5% (95% CI, 5.0% to 7.9%), and 10.8% (95% CI, 9.4% to 12.3%), whereas the efficiency of each strategy was 22.4% (95% CI, 22.5% to 26.3%), 52.7% (95% CI, 50.5% to 54.9%), and 87.8% (95% CI, 86.3% to 89.2%), respectively. CONCLUSIONS: Physician gestalt was safer but less efficient than existing models. Clinical prediction models could help reduce the overuse of blood cultures.

BACKGROUND: The burden of COVID-19 on healthcare workers (HCWs) is reported to be increasing, yet the psychometric scales now in use evaluate only single aspects; few measure the pandemic-specific burden on HCWs comprehensively. OBJECTIVE: To develop a scale to quantify the physical, mental, and socioeconomic burden of the COVID-19 pandemic on HCWs. DESIGN: Scale development and cross-sectional survey. PARTICIPANTS: Consenting HCWs aged ≥20. MAIN MEASURES: Development of an item-list based on literature reviews and HCW panel input, evaluation of content validity and item selection using the Delphi method, psychometric testing conducted on HCWs, validity assessment by factor analyses and hypothesis verification, internal consistency evaluation by Cronbach's alpha, test-retest analysis, and interpretability assessment. KEY RESULTS: Through the Delphi process, a 29-item pilot scale was generated. In psychometric testing, data from 863 HCWs contributed to the development of the final version of this scale, called Pandemic Burden Index twenty for HCWs (PBI-20), a 20-item scale to measure six domains: fatigue, fear of infection, inadequacy as a medical professional, mental health concerns, prejudice or discrimination, and anxiety about one's livelihood and daily life. Factor analysis showed each factor corresponded to the six domains of this scale. Hypothesis verification showed the PBI-20 total score to be moderately to highly correlated with the Short Form 36 vitality score and mental health score and with intention of turnover. The PBI-20 had good internal consistency (Cronbach's alpha 0.92). Test-retest analysis showed the intraclass correlation coefficient to be 0.70 and the minimal important change to be -7.0. CONCLUSIONS: The psychometrically sound questionnaire we developed to measure pandemic-specific burdens for HCWs provides an understanding of comprehensive burdens on HCWs and may serve to evaluate interventions to reduce the burdens.

PURPOSE: We developed a simple self-checkable screening tool for chronic prostatitis (S-CP) and internally validated it to encourage men (in the general population) with possible chronic prostatitis to consult urologists. METHODS: The expert panel proposed the S-CP, which comprises three domains: Area of pain or discomfort (6 components), accompanying Symptom (6 components), and Trigger for symptom flares (4 components). We employed logistic regression to predict chronic prostatitis prevalence with the S-CP. We evaluated the predictive performance using data from a representative national survey of Japanese men aged 20 to 84. We calculated the optimism-adjusted area under the curve using bootstrapping. We assessed sensitivity/specificity, likelihood ratio, and predictive value for each cutoff of the S-CP. RESULTS: Data were collected for 5,010 men-71 (1.4%) had a chronic prostatitis diagnosis. The apparent and adjusted area under the curve for the S-CP was 0.765 [95% confidence interval (CI) 0.702, 0.829] and 0.761 (0.696, 0.819), respectively. When the cutoff was two of the three domains being positive, sensitivity and specificity were 62.0% (95% CI 49.7, 73.2) and 85.4% (95% CI 84.4, 86.4), respectively. The positive/negative likelihood ratios were 4.2 (95% CI 3.5, 5.2) and 0.45 (95% CI 0.33, 0.60), respectively. The positive/negative predictive values were 5.7 (95% CI 4.2, 7.6) and 99.4 (95% CI 99.1, 99.6), respectively. CONCLUSION: The reasonable predictive performance of the S-CP indicated that patients (in the general population) with chronic prostatitis were screened as a first step. Further research would develop another tool for diagnostic support in actual clinical settings.

BACKGROUND: The shock index (heart rate divided by systolic blood pressure) of trauma patients upon emergency department arrival predicts blood loss and death. However, some patients with normal shock indices (0.4 < shock index <0.9) upon emergency department arrival also have poor prognoses. This study aimed to determine whether abnormal prehospital shock indices in trauma patients with normal shock indices upon emergency department arrival were predictors of a high risk of mortality. METHODS: We conducted a retrospective cohort study of emergency department-admitted trauma patients from 2004 to 2017. The study included 89,495 consecutive trauma patients aged ≥16 years, with Abbreviated Injury Scale score of ≥3, who were transported to the emergency department directly from the field and had a normal shock index upon emergency department arrival. According to the prehospital shock index scores, the patients were categorized into low shock index (≤ 0.4), normal shock index, and high shock index (≥0.9) groups. Odds ratios and 95% confidence intervals were calculated using logistic regression analysis. RESULTS: The 89,495 patients had a median age of 64 (interquartile range: 43-79) years, and 55,484 (62.0%) of the patients were male. There were 1350 (1.5%) 24-h deaths in total; 176/4263 (4.1%), 1017/78,901 (1.3%), and 157/6331 (2.5%) patients were in the low, normal, and high prehospital shock index groups, respectively. The adjusted odds ratios for 24-h mortality compared with the normal shock index group were 1.63 (95% confidence interval: 1.34-1.99) in the low shock index group and 1.62 (95% confidence interval: 1.31-1.99) in the high shock index group. CONCLUSION: Trauma patients with abnormal prehospital shock indices but normal shock indices upon emergency department arrival are at a higher risk of 24-h mortality. Identifying these indices could improve triage and targeted care for patients.

BACKGROUND: In older adults, the diagnosis of acute pyelonephritis is challenging because of non-specific symptoms and false-positive urine test results. Few studies have investigated the diagnostic performance of computed tomography (CT) signs. PURPOSE: To evaluate the diagnostic performance of CT signs for acute pyelonephritis in older patients suspected of infection with unknown focus. MATERIAL AND METHODS: This cross-sectional study was conducted between 2015 and 2018. Patients aged ≥65 years who underwent blood cultures, urine culture, and non-contrast or contrast-enhanced CT on admission were included. Cases with clinically presumable infection focus before CT were excluded. Two radiologists blinded to clinical information independently reviewed five CT signs: perirenal fat stranding; pelvicalyceal wall thickening and enhancement; renal enlargement; thickening of Gerota's fascia; and area(s) of decreased attenuation. The final diagnoses were made by a clinical expert panel. RESULTS: Among 473 eligible patients, 61 were diagnosed with acute pyelonephritis. When the laterality of findings between the left and right kidneys were considered, the positive and negative likelihood ratios of perirenal fat stranding were 4.0 (95% confidence interval [CI] = 2.3-7.0) and 0.8 (95% CI = 0.7-0.9) in non-contrast CT, respectively. The other signs in non-contrast CT showed similar diagnostic performance with positive and negative likelihood ratios of 3.5-11.3 and 0.8-0.9, respectively. CONCLUSION: CT signs can help physicians diagnose acute pyelonephritis in older patients suspected of infection with unknown focus.

BACKGROUND: Although respiratory rate has been a sensitive predictor for prognosis in acute settings, resting respiratory rate (RRR) is undervalued in chronic care. The clinical significance of RRR among older people is not well documented. AIM: We investigated the association between RRR and all-cause mortality among older outpatients. METHODS: A retrospective cohort study exhaustively included patients who had undergone medical checkups in a facility between April 2017 and March 2018 and followed up for at least 2 years. We excluded patients who were less than 60 years of age or had not undergone regular outpatient appointments. Sex, age, smoking habits, history of hospitalization, polypharmacy, long-term care insurance certification status, Mazzaglia index, pulse rate, systolic blood pressure, and Charlson Comorbidity Index were measured at the baseline medical checkup. Survival was confirmed by chart review and by contacting physicians in charge. The risk ratios were estimated by converting the odds ratios derived from the multivariable logistic regression models. RESULTS: Of the 853 patients who underwent baseline checkups, 749 were enrolled in the analyses; death occurred in 53 patients (7.1%), with no loss to follow-up. The RRR was independently associated with all-cause mortality after adjusting for covariates [adjusted risk ratio of RRR per 1 bpm = 1.14, 95% confidence interval (CI): 1.06 - 1.22]. DISCUSSION: Given the independent association of RRR for existing predictors, this simple index seems worthy of consideration in further studies aimed at defining its predictive role in older people and in different settings. CONCLUSION: RRR was independently associated with all-cause mortality.

BACKGROUND & AIMS: Improvement of fatty liver may be required for remission of type-2 diabetes. However, there is no longitudinal evidence on whether fatty liver reduces the chances for remission of type-2 diabetes. We investigated the association between fatty liver and remission of type-2 diabetes (the primary analysis), and also the association between improvement of fatty liver and remission of type-2 diabetes (the secondary analysis). METHODS: We collected data from 66961 people who underwent screening for type-2 diabetes from 2008 through 2016 at a single center in Japan. The primary analysis included 2567 patients with type-2 diabetes without chronic renal failure or a history of hemodialysis who underwent ultrasonography to detect fatty liver, all of whom had follow-up testing, including blood testing, for a median 24.5 months after the baseline ultrasonography. The secondary analysis included 1833 participants with fatty liver at baseline who underwent a second ultrasonography, and participants who had fatty liver at baseline but not at the second visit were considered to have had improvement of fatty liver. Remission of type-2 diabetes was defined as a fasting plasma glucose level below 126 mg/dL and an HbA1c level below 6.5% for more than 6 months without anti-diabetic drugs. Odds ratios (ORs) of remission of type-2 diabetes were estimated using logistic-regression models. RESULTS: A lower proportion of patients who had fatty liver detected by ultrasonography at baseline (8.7%, 167/1910) had remission of type-2 diabetes during the follow-up period than patients without fatty liver (13.1%, 86/657). Fatty liver at baseline was associated with a lower odds of remission of type-2 diabetes (multivariable-adjusted OR, 0.51; 95% CI, 0.37-0.72). A higher proportion of patients who had improvement of fatty liver had remission of type-2 diabetes (21.1%, 32/152) than patients with no improvement of fatty liver (7.7%, 129/1681). Improvement of fatty liver was associated with a higher odds of remission of type-2 diabetes (multivariable-adjusted OR, 3.08; 95% CI, 1.94-4.88). CONCLUSIONS: Over a follow-up period of approximate 2 years, remission of type-2 diabetes was less common in people with fatty liver detected by ultrasonography, and improvement of fatty liver was independently associated with type-2 diabetes remission.

PURPOSE: Little is known about the fall risk of older adults with overactive bladder, especially in the absence of urgency incontinence. We evaluated the impacts of overactive bladder with and without urgency incontinence (overactive bladder wet and overactive bladder dry) on the fall risk in older adults, and investigated the importance of overactive bladder as a predictor of falls by using tree based models. MATERIALS AND METHODS: This prospective cohort study included 630 community dwelling, independent older adults 75 years old or older who attended a health checkup in 2017 with a 1-year followup. The associations of overactive bladder dry and overactive bladder wet with a fall history, and future fall risk compared to no overactive bladder were assessed using logistic regression models. The contribution of overactive bladder as a predictor of falls was examined using a random forest and decision tree approach. RESULTS: Of the 577 analyzed participants (median age 79 years), 273 (47%) were men. The prevalence of overactive bladder dry and overactive bladder wet at baseline was 15% and 14%, respectively. Multivariable logistic regression analysis revealed that both overactive bladder dry and overactive bladder wet were associated with a higher likelihood of prior falls (adjusted ORs vs no overactive bladder 2.03 and 2.21, respectively; 95% CI 1.23-3.37 and 1.29-3.78, respectively). Among the 363 participants without a fall history, the adjusted ORs (95% CIs) of overactive bladder dry and overactive bladder wet for the occurrence of falls during the 1-year followup were 2.74 (1.19-6.29) and 1.35 (0.47-3.87), respectively. The tree based approach used for all participants showed that overactive bladder was an important predictor of falls in adults without a fall history, and the model had 83.6% accuracy and 81.8% AUC. CONCLUSIONS: Overactive bladder, even in the absence of urgency incontinence, is an important predictor of falls in older adults with a low absolute fall risk.

BACKGROUND: Most adult patients are willing to discuss advance care planning before the onset of any illness. There might be differences in preferences for timing when it comes to initiating advance care planning discussions by healthcare providers with patients. OBJECTIVE: To identify healthcare providers' willingness to initiate advance care planning discussions in Japan. DESIGN: A mixed-methods questionnaire comprising three case scenarios based on three different illness trajectories. PARTICIPANTS: The study participants were physicians and nurses employed in four community hospitals in Japan. MAIN MEASURES: Percentages of physicians' and nurses' willingness to initiate advance care planning discussions at four stages of patients' illness trajectory were quantitatively determined, and perceptions on preferred timing were qualitatively identified. KEY RESULTS: From 108 physician and 123 nurse respondents (response rate: 99%), 291 physician and 362 nurse responses about three case scenarios were obtained. Overall, 51.2% of physicians and 65.5% of nurses (p < 0.001) accepted discussion before illness. Less than one-third of physicians considered advance care planning a "wise precaution," while about two-thirds of nurses did. Additionally, more than half of both physicians and nurses preferred to postpone advance care planning until the patient's imminent death. CONCLUSIONS: Physicians are less willing than nurses to begin advance care planning discussions before patients' health has deteriorated though most prefer to wait until the patients are close to death. Healthcare providers' attitudes toward advance care planning will need to be addressed to improve rates of completion in Japan.

PURPOSE: To evaluate the association between being underweight and shockwave lithotripsy outcomes. METHODS: This retrospective two-centre cohort study conducted in Japan involved 597 patients diagnosed with a single urinary tract calculus based on computed tomography and who underwent shockwave lithotripsy between 2006 and 2016. We divided the patients into four groups based on their body mass index (underweight, ≤ 18.4; normal weight, 18.5-24.9; overweight, 25-29.9; obese, ≥ 30 kg/m2). We performed multivariable logistic regression analysis and estimated the odds ratio for success of single-session shockwave lithotripsy. RESULTS: Of the 597 patients, 25 (4.2%) were underweight and 34 (5.7%) were obese. After adjusting for age, sex, calculus localisation, maximum stone length, mean stone density, and skin-to-stone distance, being underweight showed a significantly negative association with success of single-session shockwave lithotripsy (odds ratio 0.25, 95% confidence interval 0.09-0.69) compared to being normal weight. CONCLUSIONS: This study showed the negative impact of being underweight on the outcomes of shockwave lithotripsy in patients with upper urinary tract calculi. This finding provides a novel viewpoint regarding the body mass index and should aid improved treatment selection for patients with upper urinary tract calculi.

BACKGROUND: Breaches of ethics undermine the practice of medicine. In Japan, two major scandals involving clinical research and drug marketing occurred after the publication of clinical trials. To study the effects of those scandals, we evaluated changes in the use of first-generation angiotensin II receptor blockers (ARBs) after publication of relevant clinical trials and also after the subsequent scandals. METHODS: We conducted a quasi-experimental design of an interrupted time series analysis (ITSA) on nationwide monthly drug-market data covering 12 years (2005 to 2017) in Japan. The main outcome was the use of first-generation ARBs (valsartan, candesartan, and losartan). The two exposures were the publication of ARB-related clinical-trial results (October 2006) and subsequent ARB-related scandals involving research and marketing (February 2013). A generalized estimating equation model was fitted for ITSA with a log link, Poisson distribution, robust variance estimators, and seasonality adjustment. RESULTS: The publication of clinical trials was associated with 12% increase in the use of first-generation ARBs in Japan, and the subsequent ARB-related scandals was associated with 19% decrease. The decrease in the use of first-generation ARBs after the scandals was greater than the increase in their use after the publication of clinical-trial results. The net effect of the two exposures was a 9% decrease in the use of first-generation ARBs. CONCLUSIONS: The scandals were associated with decrease in the use of first-generation ARBs, and that decrease was greater than the increase associated with the publication of "successful" clinical trials, making the net effect not zero but negative.

BACKGROUND: Primary tumor resection (PTR) before commencing systemic chemotherapy in patients with stage IV colorectal cancer and unresectable metastases (mCRC) remains controversial. This study aimed to assess whether PTR before systemic chemotherapy is associated with mortality in mCRC patients, after adjusting for confounding factors, such as the severity of the primary tumor and metastatic lesions. METHODS: We analyzed hospital-based cancer registries from nine designated cancer hospitals in Fukushima Prefecture, Japan. Patients were divided into two groups (PTR and non-PTR), based on whether PTR was performed as initial therapy for mCRC or not. The primary outcome was all-cause mortality. Kaplan-Meier survival analysis was performed, and survival estimates were compared using the log-rank test. Adjusted hazard ratios were calculated using Cox regression to adjust for confounding factors. All tests were two-sided; P-values < 0.05 were considered statistically significant. RESULTS: Between 2008 and 2015, 616 mCRC patients were included (PTR: 414 [67.2%]; non-PTR: 202 [32.8%]). The median follow-up time was 18.0 (interquartile range [IQR]: 8.4-29.7) months, and 492 patients (79.9%) died during the study period. Median overall survival in the PTR and non-PTR groups was 23.9 (IQR: 12.2-39.9) and 12.3 (IQR: 6.2-23.8) months, respectively (P < 0.001, log-rank test). PTR was significantly associated with improved overall survival (adjusted hazard ratio: 0.51; 95% confidence interval: 0.42-0.64, P < 0.001). CONCLUSIONS: PTR before systemic chemotherapy in patients with mCRC was associated with improved survival.

BACKGROUND: The relationship between advance care planning and religious beliefs, which are important for palliative care, is controversial in Western countries and has not been verified in Asian countries. AIM: To investigate the association between advance care planning discussions and religious beliefs in Japan. DESIGN: A nationwide survey conducted in 2016 using a quota sampling method to obtain a representative sample of Japan's general population. SETTING/PARTICIPANTS: We analyzed responses from 3167 adults aged 20-84 years (mean age ± standard deviation, 50.9 ± 16.8 years). The outcome was measured by asking whether the respondents had ever discussed advance care planning, and the main exposure by whether they had any religious beliefs or affiliations, and if so, their degree of devoutness. We analyzed religious beliefs, affiliations, and devoutness in relation to the occurrence of discussions using multivariable logistic regression models adjusted for possible sociodemographic covariates. RESULTS: Compared with respondents without, those with religious beliefs had significantly higher odds of having had discussions (adjusted odds ratio: 1.45, 95% confidence interval: 1.22-1.73). The devoutness of religious belief was proportional to the propensity of the occurrence of discussions (p for trend < 0.001). In addition, Buddhists and Christians had higher odds of having had discussions than did nonbelievers. CONCLUSION: The results suggest that holding religious beliefs, especially in Japanese Buddhism and Christianity, facilitates advance care planning discussions among Japanese adults, and thus, may help health-care providers identify those prioritized for facilitating engagement in advance care planning, especially in palliative and spiritual care settings.

BACKGROUND: In most surgical textbooks, it has been stated that pain almost always precedes vomiting in patients with appendicitis. However, the usefulness of this classic history item, "pain before vomiting", has been investigated in only one study nearly 50 years ago, in which the cause of abdominal pain could not be identified in more than 40% of patients. Accordingly, our objective was to evaluate the performance of pain before vomiting for the diagnosis of acute appendicitis in patients who presented with both acute abdominal pain and vomiting. METHODS: A retrospective chart review of adult outpatients with abdominal pain and vomiting at three acute care hospitals was performed. The reference standard for appendicitis was a CT scan evaluated by two radiologists. Diagnostic performance of pain before vomiting and the value it added to the Alvarado score were evaluated. RESULTS: Among 310 patients, 24 patients were diagnosed with appendicitis. Diagnostic performance of pain before vomiting was a sensitivity of 95.8% (95% confidence interval [CI] 79.8-99.3) and a specificity of 16.6% (95% CI 12.6-21.4). When combined with the Alvarado score, it ruled out appendicitis in an additional 12% (increased from 32% to 44%) of patients without any false negatives. CONCLUSIONS: "Pain before vomiting" is useful for ruling out appendicitis in patients with abdominal pain and vomiting.

PURPOSE: There is a paucity of data on the effect of intraoperative end-tidal carbon dioxide (EtCO2) levels on postoperative mortality. The purpose of this study was to investigate the relationship between intraoperative EtCO2 and 90-day mortality in patients undergoing major abdominal surgery under general anesthesia. METHODS: We conducted a historical cohort study of patients undergoing major abdominal surgery under general anesthesia at Kyoto University Hospital. We measured the intraoperative EtCO2, and patients with a mean EtCO2 value < 35 mm Hg were classified as low EtCO2. The time effect was determined based on minutes below an EtCO2 of 35 mm Hg, and cumulative effects were evaluated by measuring the area under the threshold of 35 mm Hg for each patient. RESULTS: Of 4,710 patients, 1,374 (29%) had low EtCO2 and 55 (1.2%) died within 90 days of surgery. Multivariable Cox regression analysis-adjusted for age, American Society of Anesthesiologists Physical Status classification, sex, laparoscopic surgery, emergency surgery, blood loss, mean arterial pressure, duration of surgery, type of surgery, and chronic obstructive pulmonary disease-revealed an association between low EtCO2 and 90-day mortality (adjusted hazard ratio, 2.2; 95% confidence interval [CI], 1.2 to 3.8; P = 0.006). In addition, severity of low EtCO2 was associated with an increased 90-day mortality (area under the threshold; adjusted hazard ratio; 2.9, 95% CI, 1.2 to 7.4; P =0.02); for long-term exposure to an EtCO2 < 35 mm Hg (≥ 226 min), the adjusted hazard ratio for increased 90-day mortality was 2.3 (95% CI, 0.9 to 6.0; P = 0.08). CONCLUSION: A mean intraoperative EtCO2 < 35 mm Hg was associated with increased postoperative 90-day mortality.
RéSUMé: OBJECTIF: Il n'existe que très peu de données s'intéressant à l'effet du niveau peropératoire télé-expiratoire du dioxyde de carbone (EtCO2) sur la mortalité postopératoire. L'objectif de cette étude était d'examiner la relation entre l'EtCO2 peropératoire et la mortalité à 90 jours chez des patients subissant une chirurgie abdominale majeure sous anesthésie générale. MéTHODE: Nous avons réalisé une étude de cohorte historique portant sur des patients subissant une chirurgie abdominale majeure sous anesthésie générale à l'Hôpital universitaire de Kyoto. Nous avons mesuré l'EtCO2 peropératoire, et les patients avec une valeur moyenne d'EtCO2 < 35 mmHg ont été catégorisés comme EtCO2 faible. L'effet temps a été déterminé en fonction de la durée, en minutes, avec une EtCO2 inférieure à 35 mmHg, et les effets cumulatifs ont été évalués en mesurant l'aire sous le seuil de 35 mmHg pour chaque patient. RéSULTATS: Sur 4710 patients, 1374 (29 %) avaient une EtCO2 faible et 55 (1,2 %) sont décédés dans les 90 jours suivant la chirurgie. Une analyse de régression multivariée de Cox, ajustée pour tenir compte des facteurs suivants : âge, statut physique selon l'American Society of Anesthesiologists, sexe, chirurgie par laparoscopie, chirurgie d'urgence, pertes de sang, tension artérielle moyenne, durée de la chirurgie, type de chirurgie et maladie pulmonaire obstructive chronique, a révélé une association entre une EtCO2 faible et la mortalité à 90 jours (rapport de risque ajusté, 2,2; intervalle de confiance [IC] à 95 %, 1,2 à 3,8; P = 0,006). De plus, la sévérité de l'EtCO2 basse était associée à une augmentation de la mortalité à 90 jours (aire sous le seuil; rapport de risque ajusté; 2,9, IC 95 %, 1,2 à 7,4; P =0,02); pour une exposition à long terme à une EtCO2 < 35 mmHg (≥ 226 minutes), le rapport de risque ajusté pour une mortalité accrue à 90 jours était de 2,3 (IC 95 %, 0,9 à 6,0 ; P = 0,08). CONCLUSION: Une EtCO2 peropératoire moyenne < 35 mmHg était associée à une augmentation de la mortalité postopératoire à 90 jours.

PURPOSE: To determine whether abnormalities of the sagittal modifiers (SMs) of the Scoliosis Research Society (SRS)-Schwab classification truly reflect back pain (BP)-specific quality of life (QOL), it is necessary to examine their dose-response relationships and to determine clinically impactful thresholds for declines in BP-specific QOL. This study aimed to analyse the continuous dose-response relationship between each SM and BP-specific QOL. METHODS: This cross-sectional study, using data from a Japanese population-based cohort study, included 519 community-dwelling residents aged ≥ 50 years who participated in the annual health examination. The participants completed the Roland-Morris Disability Questionnaire (RDQ) on BP-specific QOL. Spino-pelvic alignment based on SMs was assessed by whole-spine X-ray examinations. We fitted general linear models with or without nonlinear terms to estimate the dose-response relationship between each SM and BP-specific QOL. RESULTS: Pelvic tilt, pelvic incidence minus lumbar lordosis (PI-LL), and sagittal vertical axis showed dose-response relationships with BP-specific QOL measured as the RDQ score. PI-LL was most likely to predict a minimally clinically important RDQ score when its value exceeded the 90th percentile. A nonlinear relationship between PI-LL and the BP-specific QOL score was found. RDQ increased when PI-LL exceeded 10°. CONCLUSION: PI-LL might be the most sensitive of the three modifiers of the SRS-Schwab classification for determining BP-specific QOL. Moreover, BP-specific QOL worsens rapidly when the compensatory mechanism against malalignment exceeds a critical value. Therefore, we suggest that traditional classifications and surgical strategies should be re-examined regarding the dose-dependent abnormalities of the SMs to develop a more reliable classification strategy.

Although hospitalized patients with acute decompensated heart failure (ADHF) have severe physical dysfunction, little data are available on the comparative effectiveness of early versus late rehabilitation. This study examined the relationship between early compared to late rehabilitation and physical function among older patients hospitalized for ADHF. METHODS: In a retrospective cohort study, independent patients aged ≥65 years at baseline who were hospitalized for ADHF from 2012 to 2014 and underwent inpatient rehabilitation were identified using Emergency Department visit data and electronic medical records at two hospitals. Patients were classified into those who underwent early rehabilitation (initiated within 72 hours of admission) and late rehabilitation (after 72 hours). Primary outcome was length of time from admission until the patient was able to walk independently. Multivariable competing-risk regression with death as the competing event was used to adjust for potential confounding factors, and multiple imputation (MI) analysis was performed. RESULTS: Of 259 individuals, 30 (11.6%) commenced rehabilitation within 72 hours after admission while 229 (88.4%) did so 72 hours after admission. Patients who received early rehabilitation had a higher rate of unassisted walking for at least 40 m by 30 days after admission (hazard ratio: 8.03; 95% confidence interval: 2.15 to 29.98; Pâ¯=â¯.002 in the multivariable adjusted model) than those who received late rehabilitation. Similar findings were observed on MI analysis. CONCLUSION: Early rehabilitation therapy commenced within 72 hours of admission was associated with a higher rate of recovery of an activity of daily living (independent walking on a level surface).

BACKGROUND: The quality of care received by a growing number of older patients with chronic kidney disease (CKD) has not been adequately examined. OBJECTIVE: The objective of this study was to assess the quality of CKD care among older patients and to clarify its association with the incidence of end-stage renal disease (ESRD). RESEARCH DESIGN: This was a population-based cohort study. SUBJECTS: Older (65 y and above) CKD patients diagnosed between October 2010 and September 2014 from the National Database of Health Insurance Claims of Japan. MEASURES: A composite quality score (QS) of 3 quality measures for CKD care during the 6 months after CKD diagnosis was computed. The validated quality measures included urine testing for proteinuria, nutritional guidance, and nonsteroidal anti-inflammatory drugs avoidance. To assess the association between the QS and ESRD incidence, we used instrumental variable analysis after stratification for the history of diabetes. RESULTS: Among the 890,773 older CKD patients, 2.9% progressed to ESRD (incidence rate of 12.5 per thousand person-years). In total, 59.9% underwent urine testing, 4.5% received nutritional guidance, and 91.2% avoided regular use of nonsteroidal anti-inflammatory drugs. An instrumental variable analysis revealed that a higher QS was associated with-lower ESRD incidence in patients diagnosed with diabetes (hazard ratio: 0.25, 95% confidence interval: 0.24-0.27 for each point higher score) but not in patients without a diagnosis of diabetes (hazard ratio: 0.99, 95% confidence interval: 0.92-1.05). CONCLUSION: Among older CKD patients, quality of CKD care varied between patients, and better quality of CKD care was associated with a lower ESRD incidence in patients with diabetes but not in nondiabetic patients.
