Long-term outcomes of Holmium laser enucleation of prostate and predictive model for symptom recurrence.

INTRODUCTION AND OBJECTIVES: Holmium laser enucleation of prostate (HoLEP) represents one of the most studied surgical techniques for benign prostatic hyperplasia (BPH). Its efficacy in symptom relief has been widely depicted. However, few evidence is available regarding the possible predictors of symptom recurrence. We aimed to evaluate long-term outcomes, symptom recurrence rate, and predictors in patients that underwent HoLEP. MATERIALS AND METHODS: We retrospectively analyzed data from patients that consecutively underwent HoLEP for BPH from 2012 to 2015 at two tertiary referral centers. Functional outcomes were evaluated by uroflowmetry parameters and International Prostate Symptom Score (IPSS) questionnaire administration at follow-up visits at 12, 24, and 60 months. The primary outcome was the symptomatic patients' rate presenting lower urinary tract symptoms (LUTS) after 60 months from surgery, defined as in case of one or more of the following: IPSS more than 7, post voidal residue (PVR) more than 20 ml, need for medical therapy for LUTS or redo surgery for bladder outlet obstruction. Multivariable logistic regression analyses evaluated predictors for being symptomatic at follow-up. Covariates consisted of: preoperative peak flow rate (PFR), PVR, and IPSS, prostate volume, age (all as continuous), and surgical technique. RESULTS: A total of 567 patients were available for our analyses. Median prostate volume was 80cc, with a median PFR of 8 ml/s and median PVR of 100cc. One hundred and twenty-five (22%) patients were found to be symptomatic at follow-up. Redo surgery was needed for 25 (4.4%) patients. After adjusting for possible confounders, an increase in preoperative PVR (odds ratio [OR] 1.005) and IPSS (OR 1.12) resulted as independent predictors for symptom recurrence (all p < 0.001). CONCLUSIONS: HoLEP can provide durable symptom relief regardless of the chosen technique. Patients with an important preoperative symptom burden or a high PVR should be carefully counseled on the risk of symptom recurrence.

Latent Class Analysis of Symptom Burden Among Seriously Ill Adults at the End of Life.

BACKGROUND: Serious illness is characterized by high symptom burden that negatively affects quality of life (QOL). Although palliative care research has highlighted symptom burden in seriously ill adults with cancer, symptom burden among those with noncancer serious illness and multiple chronic conditions has been understudied. Latent class analysis is a statistical method that can be used to better understand the relationship between severity of symptom burden and covariates, such as the presence of multiple chronic conditions. Although latent class analysis has been used to highlight subgroups of seriously ill adults with cancer based on symptom clusters, none have incorporated multiple chronic conditions. OBJECTIVES: The objectives of this study were to (a) describe the demographic and baseline characteristics of seriously ill adults at the end of life in a palliative care cohort, (b) identify latent subgroups of seriously ill individuals based on severity of symptom burden, and (c) examine variables associated with latent subgroup membership, such as QOL, functional status, and the presence of multiple chronic conditions. METHODS: A secondary data analysis of a palliative care clinical trial was conducted. The latent class analysis was based on the Edmonton Symptom Assessment System, which measures nine symptoms on a scale of 0-10 (e.g., pain, fatigue, nausea, depression, anxiousness, drowsiness, appetite, well-being, and shortness of breath). Clinically significant cut-points for symptom severity were used to categorize each symptom item in addition to a categorized total score. RESULTS: Three latent subgroups were identified (e.g., low, moderate, and high symptom burden). Lower overall QOL was associated with membership in the moderate and high symptom burden subgroups. Multiple chronic conditions were associated with statistically significant membership in the high symptom burden latent subgroup. Older adults between 65 and 74 years had a lower likelihood of moderate or high symptom burden subgroup membership compared to the low symptom burden class. DISCUSSION: Lower QOL was associated with high symptom burden. Multiple chronic conditions were associated with high symptom burden, which underlines the clinical complexity of serious illness. Palliative care at the end of life for seriously ill adults with high symptom burden must account for the presence of multiple chronic conditions.

Evaluation of global and intragenic hypomethylation in colorectal adenomas improves patient stratification and colorectal cancer risk prediction.

BACKGROUND: Aberrant DNA hypomethylation of the long interspersed nuclear elements (LINE-1 or L1) has been recognized as an early event of colorectal transformation. Simultaneous genetic and epigenetic analysis of colorectal adenomas may be an effective and rapid strategy to identify key biological features leading to accelerated colorectal tumorigenesis. In particular, global and/or intragenic LINE-1 hypomethylation of adenomas may represent a helpful tool for improving colorectal cancer (CRC) risk stratification of patients after surgical removal of polyps. To verify this hypothesis, we analyzed a cohort of 102 adenomas derived from 40 high-risk patients (who developed CRC in a post-polypectomy of at least one year) and 43 low-risk patients (who did not develop CRC in a post-polypectomy of at least 5 years) for their main pathological features, the presence of hotspot variants in driver oncogenes (KRAS, NRAS, BRAF and PIK3CA), global (LINE-1) and intragenic (L1-MET) methylation status. RESULTS: In addition to a significantly higher adenoma size and an older patients' age, adenomas from high-risk patients were more hypomethylated than those from low-risk patients for both global and intragenic LINE-1 assays. DNA hypomethylation, measured by pyrosequencing, was independent from other parameters, including the presence of oncogenic hotspot variants detected by mass spectrometry. Combining LINE-1 and L1-MET analyses and profiling the samples according to the presence of at least one hypomethylated assay improved the discrimination between high and low risk lesions (p = 0.005). Remarkably, adenomas with at least one hypomethylated assay identified the patients with a significantly (p < 0.001) higher risk of developing CRC. Multivariable analysis and logistic regression evaluated by the ROC curves proved that methylation status was an independent variable improving cancer risk prediction (p = 0.02). CONCLUSIONS: LINE-1 and L1-MET hypomethylation in colorectal adenomas are associated with a higher risk of developing CRC. DNA global and intragenic hypomethylation are independent markers that could be used in combination to successfully improve the stratification of patients who enter a colonoscopy surveillance program.

Polysymptomatology in Pediatric Patients Receiving Palliative Care Based on Parent-Reported Data.

Importance: Pediatric palliative care treats patients with a wide variety of advanced illness conditions, often with substantial levels of pain and other symptoms. Clinical and research advancements regarding symptom management for these patients are hampered by the scarcity of data on symptoms as well as an overreliance on clinician report. Objective: To provide a detailed description of the symptoms among patients receiving pediatric palliative care based on parental report via a validated, structured symptom assessment measure. Design, Setting, and Participants: Baseline data for this cross-sectional analysis were collected between April 10, 2017, and February 5, 2020, from pediatric palliative care programs in 7 children's hospitals located in Akron, Ohio; Boston, Massachusetts; Birmingham, Alabama; Houston, Texas; Minneapolis, Minnesota; Philadelphia, Pennsylvania; and Seattle, Washington. Data were collected in the hospital, outpatient, and home setting from patients 30 years of age or younger who were receiving pediatric palliative care at 1 of the study sites. Exposures: Analyses were stratified by patients' demographic characteristics, including age, and by whether the patients had received a diagnosis of any of 10 non-mutually exclusive complex chronic condition categories. Main Outcomes and Measures: Twenty symptoms measured via the modified Memorial Symptom Assessment Scale, which scores the frequency and severity of any symptom that is present and provides a total symptom score. Results: Among the first 501 patients enrolled, the median age was 4.1 years (interquartile range, 0.8-12.9 years), 267 (53.3%) were male, and 356 (71.1%) were White. The most prevalent complex chronic conditions included gastrointestinal (357 [71.3%]), neurologic (289 [57.7%]), and cardiovascular (310 [61.9%]) conditions; 438 patients (87.4%) were technology dependent. Parents reported a mean (SD) of 6.7 (3.4) symptoms per patient and a median of 7 symptoms (interquartile range, 4-9 symptoms). A total of 367 patients (73.3%) had 5 or more symptoms. The 5 most prevalent symptoms were pain (319 [63.7%]; 95% CI, 59.4%-67.8%), lack of energy (295 [58.9%]; 95% CI, 54.5%-63.1%), irritability (280 [55.9%]; 95% CI, 51.5%-60.2%), drowsiness (247 [49.3%]; 95% CI, 44.9%-53.7%), and shortness of breath (232 [46.3%]; 95% CI, 41.9%-50.7%). Although older patients were reported by parents as having experienced more symptoms and having higher total symptom scores, variation across condition categories was relatively minor. Patients in the upper 10th percentile of total symptom scores had a median of 12.0 symptoms (interquartile range, 11-13). Conclusions and Relevance: In this cross-sectional study, most children receiving palliative care were experiencing polysymptomatology. An important subgroup of patients frequently experienced numerous severe symptoms. Assessment and management of patients with polysymptomatology are critical aspects of pediatric palliative care.

Comparison of Side Effects and Tolerability Between Intravesical Bacillus Calmette-Guerin, Reduced-Dose BCG and Gemcitabine for Non-Muscle Invasive Bladder Cancer.

OBJECTIVES: To compare patient-reported side effects and tolerability of full-dose Bacillus Calmette-Guérin (BCG), reduced-dose BCG, and gemcitabine one week after administration. METHODS: All patients from July 2019 to November 2020 receiving intravesical therapy (IVT) for non-muscle invasive bladder cancer (NMIBC) at our institution were surveyed before repeat instillation. Survey questions recorded IVT retention times and the duration and severity of the following side effects: bladder symptoms, fatigue, body aches, hematuria, fever, chills, and other. All responses were collected and quantified in a de-identified, password-protected database. Statistical analysis was performed using SAS JMP 13. RESULTS: Of 592 surveys completed, symptoms of any kind were reported on 463 surveys (78%) with the most common symptoms including bladder symptoms (59%), fatigue (52%), body aches (26%), and hematuria (18%). Patients were able to hold full-dose BCG, reduced-dose BCG, and gemcitabine for the protocol-specified duration 87%, 95%, and 71% of the time (P <0.05). The prevalence, severity, and duration of body aches were highest with gemcitabine (P <0.05) while the prevalence and duration of hematuria were higher with BCG (P <0.05). Reduced-dose BCG had the lowest prevalence, severity, and duration of fatigue (P <0.05). CONCLUSION: Significant differences in the side effects and tolerability of full-dose BCG, reduced-dose BCG, and gemcitabine were demonstrated using this novel survey, and these differences are of value for informing IVT selection. Evaluation of IVTs other than gemcitabine and BCG will further inform selection of therapies for NMIBC.

Measurement properties of the 12-item Short Form Health Survey version 2 in Australians with lung cancer: a Rasch analysis.

BACKGROUND: The 12-item Short-Form Health Survey version 2 (SF-12v2), a widely used, generic patient-reported measure of health status that provides summary scores of physical and mental health. No study to date has examined the measurement properties of the SF-12v2 in patients with lung cancer using Rasch analysis. The aim of this study was to extend the psychometric evaluations of the SF-12 within the lung cancer population to ensure its validity and reliability to assess the health status in this population. METHODS: Participants in the Victorian Lung Cancer Registry (VLCR) who completed the SF-12v2 between 2012 and 2016 were included in this study. The structural validity of the SF-12v2 was assessed using Rasch analysis. Overall fit to the Rasch measurement model was examined as well as five key measurement properties: uni-dimensionality, response thresholds, internal consistency, measurement invariance and targeting. RESULTS: A total of 342 participants completed the SF-12v2 three months following their lung cancer diagnosis. The SF-12 Physical Component Score (PCS-12) did not fit the overall Rasch measurement model (χ2 107.0; p < 0.001). Three items deviated significantly from the Rasch model (item fit residual beyond ± 2.5) with signs of dependency between item responses and disordered thresholds. Nevertheless, the PCS-12 was uni-dimensional with good internal consistency (person separation index [PSI] 0.83) and reasonable targeting. In contrast, the SF-12 Mental Component Score (MCS-12) had good overall model fit (χ2 35.1; p = 0.07), reasonable targeting and good internal consistency (PSI 0.81). CONCLUSIONS: Rasch analysis suggests that there is general support for the reliability of the SF-12v2 as a measure of physical and mental health in people with lung cancer. However, the appropriateness of some items (e.g. pain) in the PCS-12 is questionable and further refinement of the scale including changing the response options may be required to improve the ability of the SF-12v2 to more appropriately assess the health status of this population.

Screening tests for active pulmonary tuberculosis in children.

BACKGROUND: Globally, children under 15 years represent approximately 12% of new tuberculosis cases, but 16% of the estimated 1.4 million deaths. This higher share of mortality highlights the urgent need to develop strategies to improve case detection in this age group and identify children without tuberculosis disease who should be considered for tuberculosis preventive treatment. One such strategy is systematic screening for tuberculosis in high-risk groups. OBJECTIVES: To estimate the sensitivity and specificity of the presence of one or more tuberculosis symptoms, or symptom combinations; chest radiography (CXR); Xpert MTB/RIF; Xpert Ultra; and combinations of these as screening tests for detecting active pulmonary childhood tuberculosis in the following groups. - Tuberculosis contacts, including household contacts, school contacts, and other close contacts of a person with infectious tuberculosis. - Children living with HIV. - Children with pneumonia. - Other risk groups (e.g. children with a history of previous tuberculosis, malnourished children). - Children in the general population in high tuberculosis burden settings. SEARCH METHODS: We searched six databases, including the Cochrane Central Register of Controlled Trials, MEDLINE, and Embase, on 14 February 2020 without language restrictions and contacted researchers in the field. SELECTION CRITERIA: Cross-sectional and cohort studies where at least 75% of children were aged under 15 years. Studies were eligible if conducted for screening rather than diagnosing tuberculosis. Reference standards were microbiological (MRS) and composite reference standard (CRS), which may incorporate symptoms and CXR. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed study quality using QUADAS-2. We consolidated symptom screens across included studies into groups that used similar combinations of symptoms as follows: one or more of cough, fever, or poor weight gain and one or more of cough, fever, or decreased playfulness. For combination of symptoms, a positive screen was the presence of one or more than one symptom. We used a bivariate model to estimate pooled sensitivity and specificity with 95% confidence intervals (CIs) and performed analyses separately by reference standard. We assessed certainty of evidence using GRADE. MAIN RESULTS: Nineteen studies assessed the following screens: one symptom (15 studies, 10,097 participants); combinations of symptoms (12 studies, 29,889 participants); CXR (10 studies, 7146 participants); and Xpert MTB/RIF (2 studies, 787 participants). Several studies assessed more than one screening test. No studies assessed Xpert Ultra. For 16 studies (84%), risk of bias for the reference standard domain was unclear owing to concern about incorporation bias. Across other quality domains, risk of bias was generally low. Symptom screen (verified by CRS) One or more of cough, fever, or poor weight gain in tuberculosis contacts (4 studies, tuberculosis prevalence 2% to 13%): pooled sensitivity was 89% (95% CI 52% to 98%; 113 participants; low-certainty evidence) and pooled specificity was 69% (95% CI 51% to 83%; 2582 participants; low-certainty evidence). Of 1000 children where 50 have pulmonary tuberculosis, 339 would be screen-positive, of whom 294 (87%) would not have pulmonary tuberculosis (false positives); 661 would be screen-negative, of whom five (1%) would have pulmonary tuberculosis (false negatives). One or more of cough, fever, or decreased playfulness in children aged under five years, inpatient or outpatient (3 studies, tuberculosis prevalence 3% to 13%): sensitivity ranged from 64% to 76% (106 participants; moderate-certainty evidence) and specificity from 37% to 77% (2339 participants; low-certainty evidence). Of 1000 children where 50 have pulmonary tuberculosis, 251 to 636 would be screen-positive, of whom 219 to 598 (87% to 94%) would not have pulmonary tuberculosis; 364 to 749 would be screen-negative, of whom 12 to 18 (2% to 3%) would have pulmonary tuberculosis. One or more of cough, fever, poor weight gain, or tuberculosis close contact (World Health Organization four-symptom screen) in children living with HIV, outpatient (2 studies, tuberculosis prevalence 3% and 8%): pooled sensitivity was 61% (95% CI 58% to 64%; 1219 screens; moderate-certainty evidence) and pooled specificity was 94% (95% CI 86% to 98%; 201,916 screens; low-certainty evidence). Of 1000 symptom screens where 50 of the screens are on children with pulmonary tuberculosis, 88 would be screen-positive, of which 57 (65%) would be on children who do not have pulmonary tuberculosis; 912 would be screen-negative, of which 19 (2%) would be on children who have pulmonary tuberculosis. CXR (verified by CRS) CXR with any abnormality in tuberculosis contacts (8 studies, tuberculosis prevalence 2% to 25%): pooled sensitivity was 87% (95% CI 75% to 93%; 232 participants; low-certainty evidence) and pooled specificity was 99% (95% CI 68% to 100%; 3281 participants; low-certainty evidence). Of 1000 children, where 50 have pulmonary tuberculosis, 63 would be screen-positive, of whom 19 (30%) would not have pulmonary tuberculosis; 937 would be screen-negative, of whom 6 (1%) would have pulmonary tuberculosis. Xpert MTB/RIF (verified by MRS) Xpert MTB/RIF, inpatient or outpatient (2 studies, tuberculosis prevalence 1% and 4%): sensitivity was 43% and 100% (16 participants; very low-certainty evidence) and specificity was 99% and 100% (771 participants; moderate-certainty evidence). Of 1000 children, where 50 have pulmonary tuberculosis, 31 to 69 would be Xpert MTB/RIF-positive, of whom 9 to 19 (28% to 29%) would not have pulmonary tuberculosis; 969 to 931 would be Xpert MTB/RIF-negative, of whom 0 to 28 (0% to 3%) would have tuberculosis. Studies often assessed more symptoms than those included in the index test and symptom definitions varied. These differences complicated data aggregation and may have influenced accuracy estimates. Both symptoms and CXR formed part of the CRS (incorporation bias), which may have led to overestimation of sensitivity and specificity. AUTHORS' CONCLUSIONS: We found that in children who are tuberculosis contacts or living with HIV, screening tests using symptoms or CXR may be useful, but our review is limited by design issues with the index test and incorporation bias in the reference standard. For Xpert MTB/RIF, we found insufficient evidence regarding screening accuracy. Prospective evaluations of screening tests for tuberculosis in children will help clarify their use. In the meantime, screening strategies need to be pragmatic to address the persistent gaps in prevention and case detection that exist in resource-limited settings.

Epidemiological patterns of syndromic symptoms in suspected patients with COVID-19 in Iran: A Latent Class Analysis.

BACKGROUND: Early diagnosis and supportive treatments are essential to patients with coronavirus disease 2019 (COVID-19). Therefore, the current study aimed to determine different patterns of syndromic symptoms and sensitivity and specificity of each of them in the diagnosis of COVID-19 in suspected patients. STUDY DESIGN: Cross-sectional study . METHODS: In this study, the retrospective data of 1,539 patients suspected of COVID-19 were obtained from a local registry under the supervision of the officials at Shahroud University of Medical Sciences, Shahroud, Iran. A Latent Class Analysis (LCA) was carried out on syndromic symptoms, and the associations of some risk factors and latent subclasses were accessed using one-way analysis of variance and Chi-square test. RESULTS: The LCA indicated that there were three distinct subclasses of syndromic symptoms among the COVID-19 suspected patients. The age, former smoking status, and body mass index were associated with the categorization of individuals into different subclasses. In addition, the sensitivity and specificity of class 2 (labeled as "High probability of polymerase chain reaction [PCR]+") in the diagnosis of COVID-19 were 67.43% and 76.17%, respectively. Furthermore, the sensitivity and specificity of class 3 (labeled as "Moderate probability of PCR+") in the diagnosis of COVID-19 were 75.92% and 50.23%, respectively. CONCLUSION: The findings of the present study showed that syndromic symptoms, such as dry cough, dyspnea, myalgia, fatigue, and anorexia, might be helpful in the diagnosis of suspected COVID-19 patients.

Does Subclinical Hypothyroidism Add Any Symptoms? Evidence from a Danish Population-Based Study.

BACKGROUND: Few studies have scrutinized the spectrum of symptoms in subclinical hypothyroidism. METHODS: From 3 Danish Investigation on Iodine Intake and Thyroid Diseases (DanThyr) cross-sectional surveys performed in the period 1997 to 2005, a total of 8903 subjects participated in a comprehensive investigation including blood samples and questionnaires on previous diseases, smoking habits, alcohol intake, and education. From the 3 surveys we included patients with subclinical hypothyroidism (n = 376) and euthyroid controls (n = 7619). We explored to what extent patients with subclinical hypothyroidism reported 13 previously identified hypothyroidism-associated symptoms (tiredness, dry skin, mood lability, constipation, palpitations, restlessness, shortness of breath, wheezing, globus sensation, difficulty swallowing, hair loss, dizziness/vertigo, and anterior neck pain). In various uni- and multivariate regression models we searched for circumstances predicting why some patients have more complaints than others. RESULTS: Subclinically hypothyroid patients did not report higher hypothyroidism score [(median, interquartile range), 2 (0-4) vs 2 (0-4), P = .25] compared with euthyroid controls. Within the group of subclinical hypothyroid patients, comorbidity had the highest impact on symptoms (tiredness, shortness of breath, wheezing; all P < .001); TSH level had no impact on symptom score; and younger age was accompanied by higher mental burden (tiredness, P < .001; mood lability, P < .001; restlessness, P = .012), whereas shortness of breath was associated with high body mass index (P < .001) and smoking (P = .007). CONCLUSION: Patients with a thyroid function test suggesting subclinical hypothyroidism do not experience thyroid disease-related symptoms more often than euthyroid subjects. In subclinical hypothyroidism, clinicians should focus on concomitant diseases rather than expecting symptomatic relief following levothyroxine substitution.

Reasons for disagreement between proxy-report and self-report rating of symptoms in children receiving cancer therapies.

PURPOSE: To qualitatively describe reasons for disagreement in ratings of bothersome symptoms between child self-report and parent proxy-report. METHODS: We enrolled child and parent dyads, who understood English and where children (4-18 years of age) were diagnosed with cancer or were hematopoietic stem cell transplantation (HSCT) recipients. Each child and parent separately reported symptoms using self-report or proxy-report Symptom Screening in Pediatrics Tool (SSPedi). We then used semi-structured interviews to elicit reasons for discrepancies in symptom reporting. RESULTS: We enrolled 12 dyads in each of four age cohorts, resulting in 48 dyads. Forty-one dyads (85.4%) had disagreement in rating the presence or absence of at least one symptom. Themes identified as reasons for disagreement included (1) perception, differing perception of symptom or availability or palatability of intervention; (2) understanding, difficulty orienting to time frame or concept of bother; (3) lack of communication, including child not acknowledging or talking about experiences; (4) projection, of how the parent felt or how they assumed the child would feel; and (5) discrepancy, in how the amount of symptom bother that was initially reported on SSPedi, by either child or parent, did not align with what was reported during the dyad discussion. CONCLUSION: We identified themes that explained disagreement in ratings of bothersome symptoms between child self-report and parent proxy-report. Some disagreement may be reduced by enhancing communication about symptom reporting between child and parent. Future research should focus on methods of symptom screening that encourage communication between children with cancer and their caregivers.

Is Nasal Endoscopy of Diagnostic Value in Chronic Rhinosinusitis Without Nasal Polyps?

Endoscopic examination of the nasal cavity is an integral part of the assessment of patients with chronic rhinosinusitis. However, the benefit gained by performing endoscopy with respect to the patient's medical condition has not been completely assessed. We conducted a prospective cohort in an academic medical center. Thirty-nine patients diagnosed with chronic rhinosinusitis, without polyps, whose ailment was managed conservatively with no surgical intervention. All patients underwent nasal endoscopy, a computed tomography (CT) scan rated for Lund-MacKay score, and completed a sino nasal outcome test (SNOT)-20 questionnaire. This same evaluation was repeated 6 weeks following medical treatment. The CT scan and SNOT-20 questionnaire were independent parameters to evaluate the endoscopy score in each nasal passage. Thirty-nine (28 females) patients completed the follow-up period. A total of 156 endoscopic evaluations were performed, in which 74 nasal cavities were found to have significant pathology and 82 were either normal or displayed mild pathology. The correlation with the Lund-MacKay score was poor with a positive predictive value of 68.9% (31.1% false positive and 28% false negative). However, while looking at the SNOT-20 score, corrected for repeated measures, a higher endoscopy score was associated with a higher SNOT-20 score (odds ratio = 3.53, 95% confidence interval = 1.54-8.09, P = .003). Patients with higher endoscopy scores had a greater probability for exhibiting severe symptoms. However, we could not demonstrate a strong correlation between nasal endoscopy findings and CT scan scores. Therefore, with respect to patients with chronic rhinosinusitis without polyps, nasal endoscopy could be utilized as a beneficial objective tool.

Prevalence and Associated Dietary Factors of Rome IV Functional Gastrointestinal Disorders in Rural Western Honduras.

BACKGROUND: The literature is limited regarding the prevalence of functional gastrointestinal disorders (FGIDs) in Central America, and the role of dietary factors. METHODS: The Rome IV diagnostic questionnaire and National Cancer Institute Diet History questionnaire were administered in one-on-one interviews to a distributed cross section of the general adult population of Western Honduras. Our aim was to estimate prevalence of common FGIDs and symptoms and their relationships to dietary habits. RESULTS: In total, 815 subjects were interviewed, of whom 151 fulfilled criteria for an FGID (18.5%). Gastroduodenal FGIDs were noted in 9.4%, with epigastric pain syndrome (EPS) more common than postprandial distress syndrome, 8.5% versus 1.6%. Among bowel disorders, functional abdominal bloating (FAB) was most prevalent (6.3%), followed by irritable bowel syndrome (3.6%), functional diarrhea (FDr; 3.4%), and functional constipation (1.1%). A significant inverse association was noted between regular bean intake and any FGID (OR 0.41, 95% CI 0.27-0.63), driven by IBS and FDr. Vegetable consumption was associated with lower prevalence of functional diarrhea (OR 0.12; 95% CI 0.04-0.35) and any diarrheal disorder (OR 0.11; 95% CI 0.04-0.31). Subjects with a median daily intake of ≥ 4 corn tortillas had 1.75 (95% CI 1.22-2.50) times the odds of having any FGID. CONCLUSIONS: FGIDs were common in this rural low-resource setting in Central America, with an intriguing distribution of specific FGIDs. EPS and FAB were common, but IBS was not. Local dietary factors were associated with specific FGIDs, suggesting that diet may play a role in global variations of FGIDs.

Effect of Target Lesion Revascularization on Restenosis Lesions of the Superficial Femoral Artery without Recurred Symptoms after Endovascular Therapy.

AIM: This study aims to elucidate the effects of early application of target lesion revascularization (TLR) to restenosis lesions of the superficial femoral artery (SFA) without recurrence of symptoms. Despite recent improvements in endovascular therapy (EVT) for the SFA, restenosis remains to be a problem. However, restenosis is not always associated with the recurrence of limb symptoms. Although early application of TLR is not generally approved for restenosis lesions of the SFA without recurred symptoms, it is expected to contribute to long-term patency and other favorable outcomes. Nonetheless, its effectiveness remains to be determined. METHODS: We retrospectively analyzed 616 patients who developed restenosis after undergoing femoro-popliteal EVT for claudication (Rutherford category 1 to 3) due to de novo femoro-popliteal lesions between January 2010 and December 2016 at 11 centers in Japan. Recurred symptoms were defined as symptoms of the same or higher Rutherford categories than those immediately before the initial EVT. RESULTS: Of the patients, 291 (47 %) lacked recurred symptoms; 69 (24 %) underwent TLR for restenosis. After propensity matching, the risk of occlusion was determined to be not significantly different between the TLR and observation groups; the 3-year occlusion-free rate was 68 % and 62 %, respectively (P=0.84). The risk of recurring symptoms, critical limb ischemia, and all-cause death was also found to be comparable between groups. The incidence of target vessel revascularization was significantly higher in the TLR than in the observation group (1.55 [95 % confidence interval: 1.25-1.93] vs. 0.59 [0.41-0.85] per 3 person-years). CONCLUSIONS: In patients with SFA restenosis without recurred symptoms, early application of TLR showed no advantages.

Challenges in diagnosing head and neck cancer in primary health care.

BACKGROUND: Early diagnosis of head and neck cancer (HNC) will improve patient outcomes. The low incidence of HNC renders its detection challenging for a general practitioner (GP) in primary health care (PHC). PATIENTS AND METHODS: To examine these challenges, our cohort consisted of all patients visiting PHC centres in the City of Helsinki in 2016. We chose 57 ICD-10 codes representing a sign or symptom resulting from a possible HNC and compared data for all new HNC patients. RESULTS: A total of 242,211 patients (499,542 appointments) visited PHC centres, 11,896 (5%) of whom presented with a sign or symptom possibly caused by HNC. Altogether, 111 new HNCs were diagnosed within the Helsinki area, of which 40 (36%) were referred from PHC. The median delay from the initial PHC visit to the referral to specialist care was 5 days, whereby 88% of patients were referred within one month. CONCLUSIONS: Despite the low incidence of HNC and the large number of patients presenting with HNC-related symptoms, GPs working in PHC sort out potential HNC patients from the general patient group in most cases remarkably effectively. KEY MESSAGES For every head and neck cancer (HNC) patient encountered in the primary health care, a general practitioner (GP) will meet approximately 6000 other patients, 100 of whom exhibit a sign or a symptom potentially caused by a HNC. Despite the low incidence of HNC, GPs referred patients to specialist care effectively, limiting the median delay from the initial appointment to referral to only 5 days.

Is there any gender difference in epidemiology, clinical presentation and co-morbidities of non-functioning pituitary adenomas? A prospective survey of a National Referral Center and review of the literature.

PURPOSE: Gender differences in patients diagnosed with non-functioning Pituitary Adenomas (NFPA) in a National Referral Center for Pituitary Tumors at the Federico II University of Naples, Italy. METHODS: Patients newly diagnosed with non-functioning sellar masses found on pituitary Magnetic Resonance Imaging from January 1st 2016 to December 31th 2018 underwent anthropometric measurements, basal evaluation of pituitary function, and metabolic assessment. Fatty live index (FLI) and visceral adiposity index (VAI) were calculated. RESULTS: Seventy-three patients (35 males, 51.1 ± 17.0 years; 38 females, 41.8 ± 18.1 years) presented with NFPA. Lesions > 1 cm (85.7% vs. 47.3%; χ2 = 10.26, p = 0.001) and hypopituitarism (77.1% vs. 7.9%; χ2 = 33.29, p = 0.001) were more frequent in males than females. The highest sizes of pituitary adenomas were significantly associated with male gender (OR = 1.05, p = 0.049; R2 = 0.060; IC 1.00-1.10). Headache (62.8% vs. 31.6%; χ2 = 5.96, p = 0.015) and visual field deficits (57.1% vs. 26.3%; χ2 = 5.93, p = 0.015) were significantly more frequent in males than in females. There was no sex difference in obesity prevalence, but the metabolic syndrome was more common among males than females (60.6% vs. 26.3%; χ2 = 7.14, p = 0.001). FLI was also higher in males (69.6 ± 27.3 vs. 49.2 ± 31.3; p < 0.001), while there were no differences in VAI. CONCLUSIONS: Apart from the possible delay in the diagnosis induced by the gender differences in symptom presentation, the higher prevalence of macroadenomas amongst NFPA in males compared with females let to hypothesize a key role of the sex hormone profile as predictive factors of their biological behavior and metabolic profile. Further studies are, however, mandatory to better support the influence of gender differences on onset, progression, and metabolic consequences of NFPA.

Provider Variability in the Management Patterns of Increased Nonacid Reflux.

INTRODUCTION: Increased nonacid reflux is diagnosed in a subgroup of patients with gastroesophageal reflux disease who often present with reflux symptoms refractory to proton-pump inhibitor therapy. Despite the prevalence of this condition, the management approach for patients with increased nonacid reflux can often be varied and unclear. AIMS: Our primary aim was to investigate physician management patterns for patients who had received a diagnosis of increased nonacid reflux on impedance-pH studies. METHODS: Reflux studies in patients with increased nonacid reflux per Lyon Consensus criteria and management approaches were retrospectively reviewed. Reflux symptom survey, manometry findings, reflux symptom association (RSA) on reflux testing, immediate posttesting management information, and managing provider information were assessed. RESULTS: A total of 43 subjects in total were analyzed. Management plan after a diagnosis of increased nonacid reflux was decided by a gastroenterologist in over 95% of cases and varied greatly with no changes being the most common. Even among subjects with + RSA on reflux monitoring, no change in management was the most common action, although this occurred much less frequently compared to subjects with - RSA (28.6% vs. 78.6%, p < 0.01). When change in therapy occurred, medical treatment with baclofen was the most common choice (21.4%). Other management changes included medications for visceral hypersensitivity and antireflux surgery, although these changes occurred rarely. CONCLUSIONS: Abnormally increased nonacid reflux is frequently encountered on impedance-pH studies; however, management decisions vary significantly among gastroenterologists. When treatment change is implemented, they are variable and can include lifestyle modifications, medication trials, or antireflux surgery. Future development of standardized management algorithms for increased nonacid reflux is needed.

Long-Term Clinical Follow-Up of Patients With Chronic Rhinosinusitis.

OBJECTIVE: This study comprised a long-term follow-up of a cohort of patients with chronic rhinosinusitis (CRS) regarding clinical features and symptomatology. METHODS: Data from 42 patients with CRS were available from a previous study. Forty of these patients were alive and were contacted for inclusion after approximately 10 years. Patients completed a questionnaire about disease and symptoms, and underwent a clinical examination. RESULTS: Thirty-four patients (85%) responded and could be included and evaluated. For the participants in this follow-up study median length of time between initial inclusion (C1) and follow-up (C2) was 11 years (range: 8-15). In some patients the CRS shifted phenotype over time, from CRS with nasal polyposis to CRS without nasal polyposis or vice versa. The median total visual analogue score for combined sinonasal symptoms for all patients was statistically significantly reduced at follow-up. For individual patients, scores for nasal congestion, nasal discharge, facial pressure, and hyposmia were also statistically significantly reduced. The most frequently reported symptom-relieving treatments were nasal steroids and saline rinsing of the nose. Self-reported general quality of life was statistically significantly improved at C2 compared to C1. CONCLUSION: At long-term follow-up, symptoms were generally reduced and patients reported an improved quality of life. Patients can be given hope for eventual symptom relief. CRS is a chronic condition that seems to harbor the ability to alter its phenotype after several years. Topical corticosteroids and saline rinsing of the nose should be emphasized, since patients consider these treatments to be of high value.

Trends in Restricting Symptoms at the End of Life from 1998 to 2019: A Cohort Study of Older Persons.

OBJECTIVES: To describe changes in the occurrence of restricting symptoms at the end of life from 1998 to 2019 and compare these changes according to the condition leading to death. DESIGN: Prospective longitudinal study. SETTING: Greater New Haven, CT. PARTICIPANTS: A total of 665 decedents from a cohort of 754 community-living persons, 70 years or older. MEASUREMENTS: The occurrence of 16 restricting symptoms was ascertained during monthly interviews. Information on the conditions leading to death was obtained from death certificates and comprehensive assessments that were completed every 18-months. For each restricting symptom, adjusted rates (per 100 person-months) were calculated separately for six multiyear time intervals. RESULTS: From 1998 to 2019, rates decreased for five (31.3%) restricting symptoms (difficulty sleeping; chest pain or tightness; shortness of breath; cold or flu symptoms; and nausea, vomiting, or diarrhea), increased for three (18.8%: arm or leg weakness; urinary incontinence; and memory or thinking problem), and changed little for the other eight (50.0%: poor eyesight; anxiety; depression; musculoskeletal pain; fatigue; dizziness or unsteadiness; frequent or painful urination; and swelling in feet or ankles). The decrease in rates was most pronounced for shortness of breath, with a reduction from 15.0 (95% credible interval = 11.7-18.6) in 1998 to 2001 to 8.2 (95% credible interval = 5.9-10.5) in 2014 to 2019, yielding a rate ratio (95% credible interval) of 0.92 (0.86-0.98). When evaluated according to the condition leading to death, the results were similar, with 10 of the 13 statistically significant rate ratios representing decreases in rates over time and only 3 representing increases. CONCLUSION: The occurrence of most restricting symptoms at the end of life has been decreasing or stable over the past two decades. These results suggest that end-of-life care has been improving, although additional efforts will be needed to further reduce symptom burden at the end of life.

Genetic Risk Scores Identify Genetic Aetiology of Inflammatory Bowel Disease Phenotypes.

BACKGROUND AND AIMS: Inflammatory bowel disease [IBD] phenotypes are very heterogeneous between patients, and current clinical and molecular classifications do not accurately predict the course that IBD will take over time. Genetic determinants of disease phenotypes remain largely unknown but could aid drug development and allow for personalised management. We used genetic risk scores [GRS] to disentangle the genetic contributions to IBD phenotypes. METHODS: Clinical characteristics and imputed genome-wide genetic array data of patients with IBD were obtained from two independent cohorts [cohort A, n = 1097; cohort B, n = 2156]. Genetic risk scoring [GRS] was used to assess genetic aetiology shared across traits and IBD phenotypes. Significant GRS-phenotype (false-discovery rate [FDR] corrected p <0.05) associations identified in cohort A were put forward for replication in cohort B. RESULTS: Crohn's disease [CD] GRS were associated with fibrostenotic CD [R2 = 7.4%, FDR = 0.02] and ileocaecal resection [R2 = 4.1%, FDR = 1.6E-03], and this remained significant after correcting for previously identified clinical and genetic risk factors. Ulcerative colitis [UC] GRS [R2 = 7.1%, FDR = 0.02] and primary sclerosing cholangitis [PSC] GRS [R2 = 3.6%, FDR = 0.03] were associated with colonic CD, and these two associations were largely driven by genetic variation in MHC. We also observed pleiotropy between PSC genetic risk and smoking behaviour [R2 = 1.7%, FDR = 0.04]. CONCLUSIONS: Patients with a higher genetic burden of CD are more likely to develop fibrostenotic disease and undergo ileocaecal resection, whereas colonic CD shares genetic aetiology with PSC and UC that is largely driven by variation in MHC. These results further our understanding of specific IBD phenotypes.
