Challenges regarding the implementation of cervical cancer screening guidelines in Limpopo province, South Africa.

The World Health Organization's (WHO) call to eliminate cervical cancer is essential in improving structures and processes at primary healthcare facilities by galvanising change in providing cervical cancer screening services. The main objective of this study was to explore challenges affecting the implementation of cervical cancer screening guidelines in selected districts in Limpopo Province. The study was carried out at primary health care services (PHCs) in Vhembe and Mopani districts, Limpopo province. Qualitative non-experimental research design of an exploratory, descriptive and contextual nature of a qualitative paradigm to understand cervical cancer screening programme challenges from healthcare professionals' perspectives. The study population comprised two males and 16 female professional registered nurses working in Limpopo province's PHC services. The sample size was 18 professional nurses. A face-to-face interview guided by unstructured questionnaires was undertaken to elicit information regarding the implementation of cervical cancer screening services. Captured data were analysed using Tesch's open-coding method. The study revealed that the cervical cancer guidelines were not effectively implemented as there were contradictions and gaps when applying the guidelines about the management of HIV and AIDS, age restrictions and gestation. Furthermore, structural factors contributed to the inadequacy rate and failure to reach the set targets. Primary health care is an essential health care and human right; therefore, the government should ensure that guidelines and policies are supported financially and that professional nurses are capacitated for the efficient implementation of services.Contribution:Addressing the inequalities in the implementation of social policies for the prevention of cervical cancer prevention and improving the nurses' knowledge and practice behaviour regarding cervical cancer prevention are imperative.

The Incidence of Thyroid Cancer in Bethesda III Thyroid Nodules: A Retrospective Analysis at a Single Endocrine Surgery Center.

Fine-needle aspiration cytology (FNAC) is widely used to diagnose and monitor thyroid nodules. The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) is the standard for interpreting FNAC specimens. The risk of malignancy in Bethesda III nodules, also known as Atypia of Undetermined Significance (AUS), varies significantly throughout several studies published worldwide. This retrospective study examines the risk of cancer in thyroid FNAC categorized as Bethesda III as identified in the final histopathology of thyroidectomy specimens at a single endocrine surgery center. This retrospective cohort analysis included 1038 consecutive patients who underwent elective thyroid surgery with complete follow-up data between January 2020 and March 2024. Preoperative data on clinical and pathological characteristics have been collected. The final histopathology report from the thyroidectomy specimen was compared to the results of the preoperative FNAC on nodules that were judged to be Bethesda category III. Statistical methods were performed using SPSS version 29. A total of 670 ultrasound-guided FNACs (64.5%) performed during the study period were included in the final analysis. The study population was predominantly female, represented by 79.6% of patients with a mean age of 42.5 (SD 12.1), while 20.4% were male and significantly older with mean age of 45.13 years (p = 0.02). The FNAC inadequacy rate was 5.1%, which was associated with a high risk of malignancy (6 out of 34; 17.6%). Out of the total sample size of 170 patients classified as group III, 57 were found to have malignancies in final surgical histopathology, representing 33.5% of the cases within this category. The secondary gender-related outcome analysis showed that female patients classified under the Bethesda II category had a significantly higher risk of malignancy, with a rate of 21.2%, compared to males who had a malignancy rate of 3.4% in the same Bethesda category (p = 0.001, chi-square test). However, the female patients exhibited prognostically superior non-invasive tumors compared to male individuals (p = 0.02, chi-square test). This study's results indicate that Bethesda categories II and III are associated with a higher risk of malignancy in comparison to the reports of the first and third editions of the TBSRTC, particularly for female patients classified under category II.

Physicians' knowledge, attitude and practice about reporting work-related accidents in primary care

Objective: To evaluate physicians' knowledge, attitude and practice (KAP) on Work-related Accident Reports (Comunicações de Acidentes de Trabalho, CATs) in Primary Care. Methods: A cross-sectional study carried out from November 2020 to January 2021, with application of the Survey to 229 physicians from Fortaleza, Ceará. The instrument was sent electronically with questions about knowledge, attitude and practice in relation to the CAT. The project was approved by a Research Ethics Committee under opinion No. 4.263.48. Results: The highest inadequacy rate was related to practice (85.59%). Inadequate knowledge was associated with the existence of different forms of medical employment (p=0.04), inadequate practice (p<0.001) and inadequate attitude (p=0.009). Inadequate attitude was associated with inadequate practice (p=0.026) and inadequate knowledge (p=0.009). Furthermore, 88.21% of the participants (n=202) stated that they had never filled in the CAT. Inadequate practices were associated with inadequate knowledge (p<0.001) and inadequate attitude (p=0.026). Conclusion: The physicians' knowledge, attitude and practice in relation to the CAT need to be improved.

PAP-test: Possibilities and Limitations

Cervical cancer (CC) progresses slowly, and the cytological screening increases the likelihood of early detection of precancerous lesions. Cytology of the cervix is one of the primary methods of effective CC diagnosis, which, thanks to early detection and timely treatment, leads to a stable decrease in morbidity and mortality from invasive CC. The results of many studies have shown that the specificity of the conventional Pap smear test is approximately 80–100%, its sensitivity ranges from 30% to 80%, and the rate of inadequacy of this method is from 5% to 25%. With traditional smear preparation, only a small percentage of collected cells end up on the slide, while abnormal cells may be discarded and not analyzed. When viewing the slide, cells that have dried and clumped together may interfere with the visualization of atypical cells. To overcome these limitations, in 1996, as an alternative to the traditional Pap test, liquid cytology was presented – the technology of preparing slides on which the cells are placed in a single layer. This technology outperformed the conventional Pap test with improved fixation, reduced obscuring factors, and standardized cell transfer. In liquid cytology samples are collected by fully immersing the cytobrush in a vial containing a preservative liquid, whereby the cells are preserved and fixed simultaneously, unlike conventional smears where the sample is applied to a glass slide and fixed separately. Today, two main methods of preparation based on liquid cytology are known: ThinPrep and SurePath. The results of cytology are described according to the Bethesda system. The Bethesda classification is widely accepted because it corresponds to the clinical presentation, reproduces the nature of the lesions, and is therefore treatmentoriented with a desirable follow-up procedure. The indisputable advantage of the Pap test by liquid cytology is the ability to perform both cytological and molecular studies, in particular HPV, in one sample. This capability facilitated the implementation of a two-step strategy when HPV testing is used as a triage test for ASC-US or low-grade squamous intraepithelial lesion cytology, or when cytology is used to triage HPV-positive women.

Molecular analysis of endobronchial ultrasound needle aspirates in patients with non-small cell lung cancer: Results from the SCOPE database.

Molecular subtyping of non-small cell lung cancer (NSCLC) is critical in the diagnostic evaluation of patients with advanced disease. This study aimed to examine whether samples from endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) of intrathoracic lymph nodes and/or lung lesions are adequate for molecular analysis across various institutions. We retrospectively reviewed all cases of linear EBUS-TBNA with a final bronchoscopic diagnosis of NSCLC entered in the Stather Canadian Outcomes registry for chest ProcEdures database. The primary outcome was specimen inadequacy rate for each molecular target, as defined by the local laboratory or pathologist. A total of 866 EBUS-TBNA procedures for NSCLC were identified. Specimen inadequacy rates were 3.8% for EGFR, 2.5% for ALK-1 and 3.5% for PD-L1. Largest target size was not different between adequate and inadequate specimens, and rapid onsite evaluation did not increase specimen adequacy rates. One centre using next-generation sequencing for EGFR had lower adequacy rates than 2 others using matrix-assisted laser desorption/ionization time-of-flight mass spectrophotometry. EBUS-TBNA specimens have a very low-specimen inadequacy rate for molecular subtyping of non-small cell lung cancer.

Inadequate (Ax) Transbronchial Lung Transplant Biopsies—Scope and the Potential Contributing Factors

Transbronchial biopsy is the cornerstone for the evaluation of graft function after lung transplant and a standard of care to diagnose acute cellular rejection. However, the yield from these biopsies is variable, with about 15% to 50% of samples being judged as nondiagnostic, leading to additional procedures. The factors contributing to the nondiagnostic sampling have not been delineated, and the discordance in sample assessment between the bronchoscopist and pathologist has not been quantified. A retrospective cohort of patients who had bronchoscopies with biopsies for surveillance and graft assessment at a large-volume transplant center was studied. The occurrence of nondiagnostic alveolar sampling was assessed, and the patient demographics and procedural characteristics were compared with the diagnostic group. We included 128 patients in our study and found the inadequacy rate for alveolar tissue sampling to be 15.5%. The median number of passes made by the bronchoscopist was 9, and the number of samples assessed by the bronchoscopist was 8, with a median of 6 adequate samples identified by the pathologist. The frequency of previous biopsies, history of prior inadequate samples, need for a higher number of pass attempts, presence of airway abnormalities, and the use of general anesthesia increased the odds of inadequate sampling. Patients with the identified factors may be at risk of inadequate sampling on transbronchial biopsies. The bronchoscopist could consider getting additional samples to avoid a nondiagnostic alveolar sample. Further multicenter studies would help to elucidate other contributing factors.

Telecytology rapid onsite evaluation, with real-time communication between cytopathologist, cytotechnologist, and proceduralist, offers better adequacy rates for lymph node, but not thyroid, fine-needle aspirations

Rapid onsite evaluation (ROSE) decreases rates of inadequate fine-needle aspirations (FNAs). Telecytology allows pathologists to perform ROSE without being physically "on site", thereby saving cytopathologists' travel time and allowing them to perform ROSE for multiple institutions. Little research exists comparing telecytology to non-telecytology ROSE for FNA inadequacy rates. Using previously obtained quality metrics, we compared inadequacy rates for lymph node and thyroid FNAs with and without ROSE and with non-telecytology ROSE compared with telecytology ROSE. Use of ROSE was determined by the proceduralist. Type of ROSE was location-based, as only certain locations at our institution have telecytology capabilities. Chi-squared testing was used to compare proportions of populations and P value was set to 0.05. A total of 1168 lymph node and 1177 thyroid FNAs were included in our adequacy analysis. We found any ROSE decreased our inadequacy rate for both lymph node (20.4% to 12.7%, P = 0.002) and thyroid (34.7% to 4.8%, P = 7.4 × 10-18) FNAs. We found telecytology further decreased our inadequacy rate for lymph node (13.8% to 5.9%, P = 0.016), but not thyroid (3.3% to 5.0%, P = 0.34), FNAs. At our institution, when using telecytology, slides are read in real time with the cytotechnologist and the proceduralist looking at slides together near the patient bedside, while the cytopathologist is on the phone looking at slides on the computer screen via Dameware. When non-telecytology ROSE is performed, the cytotechnologist evaluates a slide, brings it to the cytopathologist's office and then the cytopathologist calls the proceduralist to discuss the slide. We believe telecytology offers an opportunity for more inclusive communication thereby improving adequacy rates for more complex cases, like lymph nodes, without affecting adequacy rates for cases where assessment of adequacy is less complex, like thyroid. This research supports use of telecytology especially for complex cases.

Nutrient Inadequacy in Korean Young Adults with Depression: A Case Control Study

The role of diet is gaining attention among the modifiable factors associated with depression; thus, this case–control study examined the association between nutrition and depression in young Korean adults. Dietary surveys in individuals with depression (n = 39) and age- and gender-matched controls (n = 76) were conducted using food records and food frequency questionnaires. Men with depression consumed less mushrooms and meat, while women consumed significantly less grains (p < 0.05). Overall, the depression group consumed less energy and nutrients, and the difference was more pronounced in men. The male depression group had lower nutrient adequacy ratio (NAR) for energy, protein, vitamin A, thiamine, niacin, folate, and phosphorus, whereas the female depression group had lower NARs for energy, protein, niacin, and vitamin B12. The depression group had a significantly lower mean adequacy ratio in both genders. Furthermore, the proportion of inappropriate nutrient intake was higher in both genders of the depression group, exhibiting significant differences in energy, protein, niacin, folate, and zinc in men and energy, riboflavin, folate, and vitamin C in women. Hence, both men and women in the depression group had poor nutrient intake and high rates of nutrient inadequacy and improper consumption. This suggests that the quantity and quality of meals should be improved for individuals with depressive symptoms.

Influence of biliary stents on the diagnostic outcome of endoscopic ultrasound-guided tissue acquisition from solid pancreatic lesions: a systematic review and meta-analysis.

This meta-analysis analyzed the effect of an indwelling biliary stent on endoscopic ultrasound (EUS)-guided tissue acquisition from pancreatic lesions. A literature search was performed to identify studies published between 2000 and July 2022 comparing the diagnostic outcomes of EUS-TA in patients with or without biliary stents. For non-strict criteria, samples reported as malignant or suspicious for malignancy were included, whereas for strict criteria, only samples reported as malignant were included in the analysis. Nine studies were included in this analysis. The odds of an accurate diagnosis were significantly lower in patients with indwelling stents using both non-strict (odds ratio [OR], 0.68; 95% confidence interval [CI], 0.52-0.90) and strict criteria (OR, 0.58; 95% CI, 0.46-0.74). The pooled sensitivity with and without stents were similar (87% vs. 91%) using non-strict criteria. However, patients with stents had a lower pooled sensitivity (79% vs. 88%) when using strict criteria. The sample inadequacy rate was comparable between groups (OR, 1.12; 95% CI, 0.76-1.65). The diagnostic accuracy and sample inadequacy were comparable between plastic and metal biliary stents. The presence of a biliary stent may negatively affect the diagnostic outcome of EUS-TA for pancreatic lesions.

Effect of a Single Multi-Vitamin and Mineral Supplement on Nutritional Intake in Korean Elderly: Korean National Health and Nutrition Examination Survey 2018-2020.

Inadequate nutritional intake is common, especially among elderly individuals. Although micronutrient intake may help fill nutritional gaps, the effects of multi-vitamin and mineral supplements (MVMS) among the Korean elderly are not well known. Therefore, we investigated the nutrition-improving effects of a single MVMS. A total of 2478 people aged ≥65 years who participated in the Korea National Health and Nutrition Survey 2018-2020 were analyzed. Nutrient intake from food and supplements was measured using the 24 h recall method. We compared the nutritional intake and insufficiency between the food-only group (n = 2170) and the food and MVMS group (n = 308). We also evaluated the differences in inadequate nutritional intake after taking MVMS with food. The analysis included vitamins A and C, thiamine, riboflavin, niacin, calcium, iron, and phosphorus. The proportion of insufficient intake ranged from 6.2% to 80.5% for men and from 21.2% to 82.4% for women, depending on the nutrients. Intake of MVMS with food was associated with lower rates of inadequacy (3.8-68.5% for men and 3.3-75.5% for women) compared to the food-only group. The results suggest that micronutrient deficiency frequently occurs in the Korean elderly population and can be improved by MVMS intake.

Prenatal assessment of high-risk pregnancies in primary and specialized outpatient care: a mixed study.

to assess high-risk prenatal care and identify strategies for improving care. a mixed study of a prospective cohort, with 319 mothers in a public maternity hospital, from October 2016 to August 2017, using a semi-structured instrument and interview. Analysis was performed using the chi-square test (p≤0.05). The qualitative approach was carried out through interviews with guiding questions to 13 managers, at their workplace, between January and March 2020, analyzed under social phenomenology. higher rates of inadequacy were identified for all criteria. However, when care was shared, there was a higher rate for performing tests (p=0.023), consultations (p=0.002), risk stratification (p=0.013) and emergency information (≤0.000). Weaknesses in the record evidenced impairment in communication and continuity of care. shared care is a strategy for improving care, however there is a need to strengthen effective referral and counter-referral to care continuity.

Conventional versus Liquid-based Cytology: "Man versus Machine".

Liquid-based cytology (LBC) can improve adequacy, monolayer quality with a clean background compared to conventional smears (CS). The objective was to compare the quality and diagnostic yield of CS and LBC in routine cytological investigations. This retrospective study consisted of 306 samples (255 gynecological, 39 nongynecological, and 12 fine needle aspiration cytology [FNAC]) during a 2-year period (2019-2020). From each patient, two samples were collected in the same manner in the same sitting and processed by CS and LBC (ThinPrep® 2000, Hologic Inc.). Both CS and LBC were compared for adequacy, quality, representativeness, inflammation, hemorrhage, necrosis, preservation, reactive changes, organisms, atypia/dysplasia/malignancy, and preparation/screening time. Statistical analysis was performed. No statistically significant difference was noted for adequacy, representativeness, reactive changes, preservation, and atypia/dysplasia/malignancy. CS was better in cellularity and diagnosis of inflammation and organisms, whereas LBC had a clean background and the difference was statistically significant (P = 0.0005). CS was equivalent to LBC in adequacy, representativeness, reactive changes, and atypia/dysplasia/malignancy. Adequacy comparable to LBC can be achieved in CS by careful sample collection, processing, and screening by trained cytotechnologists. CS was better in detecting organisms and inflammation than LBC. The advantages of LBC were monolayer smear, clean background, and lesser screening time, but the demerit was higher cost and longer processing time. Therefore, LBC is best suited to those laboratories having high sample inadequacy rates, lack of competent cytotechnologists, and no financial constraints. Either man or machine, appropriate and adequate sample collection by trained personnel forms the cornerstone for ensuring adequacy in both CS and LBC.

Benefits of Surgeon-Performed Office-Based Ultrasonography

Background and Objectives The purpose of this study was to examine the benefits of ultrasonography performed by a surgeon rather than a radiologist.Subjects and Method This retrospective study enrolled 122 cases of ultrasonography performed by a head and neck surgeon and 116 cases of the same examination performed by a radiologist before surgery. The time intervals between the first visit and surgery were compared in both groups.Results The average waiting time for surgery after the first hospital visit was significantly reduced when a surgeon performed the ultrasound examination. Furthermore, there was no significant difference in sampling inadequacy rate on thyroid fine needle aspiration (FNA) between FNA performed by a head and neck surgeon and a radiologist.Conclusion Surgeons can utilize ultrasound as a diagnostic and therapeutic tool in an office-based setting. For patients, diagnosis and treatment provided by a single doctor will lead to more efficient outcomes.

Comparison Ultrasound-Guided Handheld Vacuum Assisted Breast Biopsy and Core Biopsy in Breast Cancer

Introduction. Needle biopsy, including core needle biopsy (CNB) and vacuum-assisted breast biopsy (VABB) with or without radiological support) is the initial investigative method of choice for the preoperative diagnosis of breast lesions. Ultrasound-guided VABB (US-VABB) has become widely accepted because of its high accuracy. In this review, the diagnostic performance indices of CNB were compared with US-VABBB techniques. Method. A literature search proceeded in online databases compiling studies from the last 20 years in the PubMed, EBSCOhost, ScienceDirect, and ProQuest databases. Eighteen eligible studies compared US-VABB and CNB for diagnostic accuracy. All studies were cohort retrospective. This literature search proceeded according to the PRISMA. Results. Eighteen retrospective studies in three categories: comparative studies of US-VABB and CNB and the diagnostic accuracy of US-VABB and CNB. The studies showed that US-VABB has higher sensitivity and specificity than CNB but lower inadequacy and underestimation rates in the comparative studies group. In addition, the diagnostic accuracy of US-VABB is higher than CNB when comparing the other two subgroups (sensitivity and specificity: 94.4%-100% vs. 82%-90% and 98%-100% vs. 96%-98%, respectively). Conclusion. US-VABB has higher overall diagnosis accuracy than CNB

An innovative synthetic support for immunocytochemical assessment of cytologically indeterminate (Bethesda III) thyroid nodules.

Fine needle aspiration (FNA) is the procedure of choice in the evaluation of thyroid nodules. Nodules with indeterminate cytological categories, Bethesda III and IV, pose challenges in clinical practice and are frequently submitted to diagnostic surgery. CytoFoam Core (CFCS) uses an absorbent foam device inserted into the needle hub to collect the cytological sample aspirated during FNA. Specimen is formalin-fixed and paraffin-embedded. Assessing diagnostic efficacy of CFCS, compared to traditional cytology, in re-evaluating thyroid nodules classified as Bethesda III, using post-surgical histology as reference standard. Retrospective study on 89 patients with a first indeterminate cytological report who were referred to the Department of Endocrinology of Regina Apostolorum Hospital (Albano L. Rome, Italy) for a second FNA. FNA was performed after at least one month under ultrasound guidance with a 23G needle according to the established procedure. During the second procedure, both traditional cytological (TC) smears and a single-pass CFCS specimen were obtained for each patient. On CFCS samples immunocytochemical staining for Galectin-3, HBME-1, and CK-19 was also performed. 51 patients eventually underwent surgery, and their histological diagnoses were compared to the TC and CFCS reports. Four parameters were evaluated: inadequacy rate, rate of persistent indeterminate (Bethesda III and IV) reports, rate of malignancy in persistently indeterminate nodules, and rate of cancer in lesions cytologically classified as malignant. Non-diagnostic samples were 6 (11.8%) in TC vs 3 (5.9%) in CFCS (p=0.4). Persistent indeterminate samples were 31 (60.8%) in TC vs 19 (37.2%) in CFCS (p=0.01). Rate of malignancy in persistently indeterminate nodules was 8/19 (42.1%) in CFCS vs 9/31 (29%) in TC group (p=0.3). Nine/51 (17.6%) samples were classified as benign by TC vs 21/51 (41.2%) samples by CFCS (p<0.01). All nodules resulted benign at post-surgical evaluation. Five/51 (9.8%) samples were classified as suspicious for malignancy/malignant in TC group against 8/51 (15.7%) samples in CFCS (p=0.5). Post-surgical evaluation confirmed malignancy in all these cases. CFCS demonstrated greater diagnostic accuracy than TC in repeat FNA assessment of cytologically indeterminate nodules. CFCS increased the conclusive diagnosis rate and decreased the number of cytologically indeterminate cases.

Systematic Review and Meta-Analysis of the Diagnostic Accuracy of the International Academy of Cytology Yokohama System for Reporting Breast Fine-Needle Aspiration Biopsy in Diagnosing Breast Cancer

Objectives: The primary objective is to determine the accuracy of fine-needle aspiration biopsy (FNAB) in breast lesions reported according to the International Academy of Cytology (IAC) Yokohama system for reporting breast FNAB. The participants include any patient presenting with any breast lesion found suitable for FNAB. The target condition was breast cancer. The secondary objective was to study the proportion of inadequate FNAB in the selected studies. Methods: PubMed/MEDLINE and Embase were searched for studies having all the following key search terms: Breast AND FNAB AND Diagnostic Accuracy published in the time frame of 2017 to May 16, 2022. The Cochrane and PROSPERO databases, citations of selected articles and articles citing the selected articles were also searched. Studies assessing the diagnostic accuracy of breast FNAB in diagnosing breast cancer, which had at least 75 subjects (and at least 20 subjects each in the benign and malignant FNAB groups), were selected. The reference standard was histopathology (or adequate clinical follow-up for benign disease). Studies were screened independently by two researchers, with a consensus reached among the authors in cases of conflict. The risk of bias and applicability were assessed using the QUADAS-2 tool. Sensitivity and specificity at each diagnostic cut-off were assessed by bivariate generalized linear mixed-model meta-analysis. The area under the receiver operating characteristics curve (AUC) and inadequacy rate were assessed by random-effects meta-analysis. The confidence intervals of sensitivity, specificity, and AUC were examined against a value of 0.95. Results: Twenty-two studies, all of which were cross-sectional single-gate studies, were selected with a total of 10,886 subjects with a primary breast lesion having concurrent FNAB and reference standard reports. Sensitivity and specificity, with 95% confidence intervals, were 0.978 [0.968, 0.985] and 0.832 [0.76, 0.886] for the diagnostic cut-off of “Atypical considered positive for malignancy,” 0.916 [0.892, 0.935] and 0.983 [0.97, 0.99] for the cut-off of “Suspicious of Malignancy considered positive,” and 0.763 [0.706, 0.812] and 0.999 [0.994, 1] for the cut-off of “Malignant considered positive.” The overall AUC was 0.975 [0.962, 0.984]. FNAB sampling without imaging guidance was associated with lower inadequacy. Discussion: There is strong evidence that the overall accuracy, sensitivity for “Atypical category considered positive” and specificity when “Suspicious or Malignant categories are considered positive” of FNAB are high when using the categories of the IAC Yokohama Reporting System, demonstrating the usefulness of FNAB in diagnosing breast cancer.

Assessing ROSE for adequacy of EBUS-TBNA compared with a direct-to-cell block approach as a response to the COVID-19 pandemic.

Introduction:Rapid on-site evaluation (ROSE) has been used during the endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) procedure as standard practice. Because of the COVID-19 (coronavirus disease 2019) pandemic, our institute had had to discontinue ROSE and adopt a direct-to-cell block approach. In the present study, we aimed to determine whether this change has had significant effects on the cytopathology quality.Materials and methods:A total of 1903 EBUS-TBNA cases from 734 patients were collected (1097 cases with ROSE for 452 patients; 806 cases without ROSE but with direct-to-cell block for 282 patients). The clinical and cytology data were analyzed using SAS, version 9.4, software to render calculated standardized residuals and a fitted multivariate generalized linear model.Results:On average, a biopsy from a patient with ROSE was 0.936 (=exp −0.066) times less likely to be reported as satisfactory compared with a biopsy from a patient without ROSE, although the difference was not statistically significant (P = 0.785). The inadequacy rate of EBUS-TBNA was 6.4% higher on average for cases with ROSE compared with a direct-to-cell block approach. However, this difference was also not statistically significant. The proportions of biopsies reported as diagnostic for malignancy and other were significantly different between the ROSE and no-ROSE groups with a standardized residual of 1.80 (P = 0.036) and −2.27 (P = 0.012), respectively.ConclusionsDiscontinuing ROSE and using a direct-to-cell block approach had no negative effects on cytopathology quality. This practice can be considered acceptable during the COVID-19 pandemic when social distancing and the shortage of staff and supplies have resulted in challenges to delivering quality care to cancer patients whose treatment cannot be postponed.

Nurse-led reinforced education by mobile messenger improves the quality of bowel preparation of colonoscopy in a population-based colorectal cancer screening program: A randomized controlled trial

BackgroundAdequate bowel preparation is an important colonoscopy quality indicator. Reinforced education is effective in improving bowel preparation quality of colonoscopy with mixed indications. However, it remains unclear whether such improvement can be consistently observed in pre- and post-irrigation during colonoscopy in screening population. ObjectiveWe aimed to study the effectiveness of nurse-led reinforced education delivered via mobile messenger (WhatsApp Messenger) on pre- and post-irrigation bowel preparation adequacy in colonoscopies for positive fecal immunochemical test in a population-based colorectal cancer screening program. DesignRandomized controlled trial. SettingA hospital-based endoscopy centre in Hong Kong, China. ParticipantsPatients undergoing colonoscopy for positive fecal immunochemical test in a population-based colorectal cancer screening program. MethodsThe recruited patients were randomized to receive either WhatsApp Reinforced Education (WRE) or No Reinforced Education (NRE) (1:1). Patients in WRE group received one-off reinforced education of bowel preparation in text and video formats via WhatsApp Messenger four days prior to colonoscopy sent by investigator while NRE group received standard-of-care only.Primary outcome was the bowel preparation adequacy rate as evaluated by Aronchick Scale. Secondary outcomes included bowel preparation adequacy rate as evaluated by Boston Bowel Preparation Scale, adenoma detection rate and risk factors of bowel preparation inadequacy. Continuous variables were described as means with standard deviation (SD) and analyzed with Student's t-test. The Pearson Chi Square Test or Fisher Exact Test was used to assess categorical variables when appropriate. Risk factors were determined by logistic regression. ResultsFrom July 2017 to April 2019, 685 eligible patients were randomized to WRE (n = 343) and NRE (n = 342) groups. Patients in WRE group had higher bowel preparation adequacy rate as evaluated by Aronchik Scale (83.4% vs 75.4%, p = 0.010) and Boston Bowel Preparation Scale (94.2% vs 88.9%, p = 0.013). Adenoma detection rate was higher in WRE group but without statistical significance (71.4% vs 67.5%, p = 0.27). In logistic regression, WhatsApp Reinforced Education reduced the inadequate bowel preparation risk (Adjusted odds ratio: 0.564; 95% confidence interval: 0.371–0.856, p = 0.007). Male gender (Adjusted odds ratio [AOR]: 1.638; 95% confidence interval [CI]: 1.054–2.546, p = 0.028) and diabetes (AOR: 2.062; 95% CI: 1.215–3.497, p = 0.007) were risk factors of bowel preparation inadequacy. ConclusionsNurse-led mobile messenger-initiated reinforced education improves both pre- and post-irrigation bowel preparation quality of screening colonoscopy following positive fecal immunochemical test. It is readily incorporable in clinical practice because of its low setup cost. Registration numberRegistered on 4 July 2017 on https://clinicaltrials.gov/ (NCT03209739).

Compliance of NKF KDOQI 2020 nutrition guideline recommendations with other guideline recommendations and protein energy wasting criteria in hemodialysis patients

IntroductionNutrition in hemodialysis patients is important in decreasing complications, improving quality of life, and preventing of malnutrition. Recommendations of the guidelines are taken into consideration while prescribing a nutrition therapy plan for patients. However, the recommendations may differ between the guidelines. It was aimed to compare the newly published National Kidney Foundation Kidney Disease Outcomes Quality Initiative (NKF KDOQI) guideline with previous reported two guideline recommendations and protein energy wasting criteria in this study. Materials and methodsFifty-five maintenance hemodialysis patients between the ages of 18–65 were included in the study. Daily energy intake and daily protein intake of these patients were evaluated by three different nutrition guidelines; NKF KDOQI-2000, 2020 and European Best Practice Guidelines-2007. In addition, protein energy wasting was determined by using anthropometric measurements, biochemical findings and food intake of the patients. ResultsWhen the inadequacy rate in dietary daily energy intake and daily protein intake of the patients evaluated by NKF KDOQI-2000 recommendations, it was found to be higher than the rates in other two recommendations (P<0.05). Based on criteria, protein energy wasting was detected in 29.1% of the patients. While the NKF KDOQI-2020 daily energy intake recommendation was not consistent with other guideline recommendations, it seems highly compatible with protein energy wasting recommendations such as albumin, body mass index, mid-upper arm circumference, energy, and protein intake. While NKF KDOQI-2020 daily protein intake recommendation complies with European Best Practice Guidelines-2007 recommendations, the level of agreement with protein energy wasting criteria is very low. ConclusionInadequate protein intake is still an ongoing problem in hemodialysis patients. NKF KDOQI-2020 guidelines provide a more suitable and applicable daily energy intake recommendation for patients compared to the previous guidelines.

Role of Pathologist in the Era of Image-Guided and EUS-Guided Aspirations: A 10-Year Study at a Single Tertiary Care Oncology Institute in North India

Background: With improved and readily accessible imaging techniques, the shift in fine-needle aspiration cytology (FNAC) from palpation-guided FNA (PGFNA) to image-guided FNA (IGFNA) and endoscopic ultrasound-guided FNA (EUS-FNA) became evident in last few decades. The present study evaluates the impact of IGFNA and EUS-FNA on the practice of cytopathology at our 300-bedded oncology institute. Study Design: A 10-year audit of three aspiration modalities PGFNA, IGFNA, and EUS-FNA was done. The number of aspirates, inadequacy rates, new patient registration numbers, and tissue biopsy numbers were compared. Results: A total of 29,610 FNAC were evaluated against a total 141,333 new patient registrations over a period of 10 years. The new cancer patient registration over last 10 years showed a 56% increase, with a comparable increase of 60% in diagnostic biopsies; whereas, the number of FNAC increased by only 6%. This reduction in the number of aspirates was mainly due to fall in the number of PGFNA to 18% of all procedures in the year of 2019 from a high of 44% in 2011. Further, PGFNA showed a reduction by 50% over 3 years. The inadequacy rates of PGFNA increased to 9.1% (in 2019) from 1.6% (in 2012). The IGFNA constituted 46%–60% of procedures, with inadequacy varying from 8.5% to 12.1% over years. The EUS-FNAC gradually increased from 3% to 22% from 2013, and the inadequacy rates were variable overtime showing parallelism with the use of rapid on-site adequacy evaluation (ROSE) by the endoscopist. Inadequacy rates ranged from 7.1% (2013) to 2.6% (2016), 7.7% (2017), and 5.4% (2019). Conclusion: The utility of ROSE and diminishing role of pathologist is highlighted in our study. Judicious ROSE improves diagnostic accuracy, decreases the rate of missed diagnosis and the repetition of procedures. The study sheds light on the ever-increasing lacuna in the training of pathologists for blind as well as in image-guided FNAC. Further, it enumerates the factors leading to the underutilization of ROSE, its undisputed advantages, operator variations in procedure, smear preparation, and screening.
