intended postgraduate degree certificate.
Aim: To investigate challenges faced by postgraduate nursing students, develop strategies for overcoming these challenges, and assessing face and content validity for the proposed strategies.
Methods: The study was carried out at the Faculty of Nursing at Ain Shams University using a methodological design. The sample consisted of two groups, namely postgraduate nursing students including all master and doctorate postgraduate students in different specialties at the last semester of their studies during the academic year 2017/2018; their total number was 236 students and a Jury group (25 professors and assistant professors from different nursing faculties). Three tools were used to achieve the aim of this study. They were a self-administered questionnaire for students to investigate challenges faced during their studies, an opinionnaire sheet to examine the face and content validity of the developed questionnaire, and an opinionnaire sheet to validate the proposed strategies.
Results: The student-related challenges revealed that the psychological-related challenges had the highest mean (2.5±0.4) among the student-related challenges, while the financial-related had the lowest mean (2.2±0.5). The administrative and academic challenges were the most challenging, with a mean (2.2±0.5) for the institutional-related challenges.
Conclusion: Based on the identified challenges and their prioritization, overcoming strategies were developed and were found to have high levels of the face, and content validity by experts' opinions and Content Validity Indicator CVI was (0.99). The study recommended that the developed strategies should be presented to and discussed with postgraduate students in the study setting to improve and ensure their acceptability.

Published: February 2021

Purpose: The objective of this study was to determine women’s beliefs as influencing factors in the utilization of antenatal services.
Methodology: The quantitative cross sectional survey was conducted in both rural and urban areas of three townships of Chin State. The multi-stage sampling method was used to recruit 350 women who had given birth within the past year. They were interviewed using structured questionnaires relating to their socio-demographic characteristics, beliefs about the utilization of antenatal services, and the situation of received antenatal care. The X2 values and odd ratio with a 95% of CI were calculated to find out women’s beliefs as influencing factors in the utilization of antenatal services.
Findings: Among the 350 participants, the number who received antenatal care at least one time and four times were 303 (86.6%) and 222 (63.4%) respectively. There were only 98 (28.0%) who received antenatal care in first trimester. The number of women who showed awareness of life threatening risks of pregnancy was 135 (38.6%) whilst positive attitudes towards the effectiveness of antenatal care and accessibility of health care staff were 170 (48.6%) and 63 (18.0%) respectively. Women’s beliefs about the risks of pregnancy, effectiveness of antenatal care and accessibility of health care staff for antenatal care were statistically associated with the situation of receiving antenatal care at least four times and care in the first trimester but not associated with the situation of receiving at least one time.
Unique contribution to theory, practice and policy: Women in Chin State received late first antenatal care and lack of regular follow-up because of their beliefs about the utilization of antenatal services. Effective health education activities are needed to raise awareness about the utilization of antenatal services.

Influence of Devolution and Politics on Expansion Strategies in Public Training Institutions: A Case Study of Kenya Medical Training College
Authors: Kimwetich Daniel K. , Musango Paul Chandoo 
Published: February 2021

This study investigates the influence of devolution and politics on the expansion strategies in public training institutions with reference to the Kenya Medical Training College. The specific objectives of the study are to: establish the influence of devolution of health services on the success of expansion strategies in the public training institutions and; determine the influence of politics on the success of expansion strategies in the public training institutions. This study is based on the contingency theory. It adopts the descriptive survey design. The study focuses on 2393 KMTC officers from the 73 KMTC campuses in Kenya, 42 ministries of health officials in the 42 counties that have KMTC campuses, and 42 local leaders from those counties that have KMTC campuses. The total targeted study participants were thus 2477. From these, 10% (248 persons) were sampled. The study used purposive and stratified random sampling techniques to obtain the study sample. Primary data was collected using structured questionnaires and interviews. Data from questionnaires were analysed using the Statistical Package for the Social Sciences (SPSS) version 24. Descriptive statistics (frequencies, percentages, and means) were used to describe the central tendencies of the data. In addition, inferential statistics (Pearson Correlation and Multiple Regression Analysis) were also used. Data from key informants were analysed using content analysis techniques. The findings show that the two study variables influenced the uptake of expansion strategies at KMTC campuses. In this regard, Pearson correlation shows that there was statistical significant relationship between devolution of health services (r=0.322, p<0.001) and; politics (r=0.478, p<0.001) and success of expansion strategies. These findings show that politics was the strongest factor influencing the success of expansion strategies followed by devolution of health services. As such, avoiding the negative influences of the devolution of health services and politics can enhance the success of expansion strategies at KMTC. In this regard, efforts aimed at reducing political patronage as well as interferences of devolved governments in the running of KMTC campuses would enhance the performance of new campuses.

Abstract
Context.—Thalassemia and hemoglobinopathies are major public health problems worldwide. To establish a cost-effective screening tool for newborns in regions where the incidence of these disorders is significant, study of the hemoglobin and hematologic features of normal and thalassemic newborns is necessary.
Objective.—To study hemoglobin and hematologic characteristics of normal and various thalassemic newborns and to assess the effectiveness of simple screening methods for α-thalassemia 1 and hemoglobin E.
Design.—Study was made of 402 cord blood specimens collected from unrelated Thai individuals. Hematologic parameters and hemoglobin profiles were determined. Thalassemia mutations were identified using polymerase chain reaction–related techniques.
Results.—As many as 178 subjects (44.3%) were found to carry thalassemia genes with 18 different genotypes. All forms of α-thalassemia including double heterozygote for hemoglobin E and α-thalassemia showed significant reduction in hemoglobin, mean corpuscular volume, and mean corpuscular hemoglobin with increasing trend of red blood cell as compared with a non–α-thalassemic group. Although heterozygous hemoglobin E and β-thalassemia showed no hematologic difference from nonthalassemic group, heterozygous α-thalassemia 1 including those with hemoglobin E showed significant increase in hemoglobin Bart level.
Conclusions.—Based on these findings, effective primary screening with 100% accuracy for α-thalassemia 1 and hemoglobin E in newborns in the region could be carried out using mean corpuscular volume less than 95 fL, mean corpuscular hemoglobin less than 30 pg, or hemoglobin Bart greater than 8.0% and hemoglobin E greater than 0.5%, respectively.
Systematic Assessment of Culture Review as a Tool to Assess Errors in the Clinical Microbiology Laboratory
Authors: Goodyear Nancy , Ulness Bruce K. , Prentice Jennifer L. , Cookson Brad T. , Limaye Ajit P. 
Published: February 2021

Abstract
Context.—Daily supervisory review is a common practice in microbiology laboratories; however, there are no publications describing errors corrected by this practice.
Objective.—To determine (1) the correction rates for routinely reviewed positive cultures, (2) the correction rates for negative cultures, and (3) the types of corrections that are found, including the number with potential clinical significance.
Design.—We prospectively assessed errors identified during culture report review for all positive (10-month period) and negative (1-month period) cultures at a single, university-based clinical microbiology laboratory in the United States. Errors were classified using predefined categories, and total and per category error rates were determined. A χ2 test was used to assess significant differences between error rates.
Results.—A total of 112 108 culture reports were examined; 914 reports required a total of 1043 corrections. Of 101 703 positive culture reports, 786 (0.8%) required 900 corrections, 302 (0.3%) of which were potentially clinically significant. Of 10 405 negative culture reports, 128 (1.2%) required 143 corrections, 5 (0.05%) of which were potentially clinically significant. The rate of potentially clinically significant errors was significantly higher among positive versus negative culture reports (P &lt; .001). Errors from positive culture reports most commonly involved susceptibility (374 [42%]), reporting (275 [31%]), and identification workup (217 [24%]). Most potentially significant errors from positive culture reports involved susceptibility testing (n = 253) and specimens from wound or lower respiratory tract (P &lt; .001).
Conclusions.—Review of culture reports from positive cultures from nonsterile sites with special attention to antimicrobial susceptibility testing and reporting would be most likely to detect potentially significant errors within the clinical microbiology laboratory.
Multiple Gastrointestinal Stromal Tumors and Lipomatosis
Authors: Liu Xiuli , Wilcox Charles Melbern , Nodit Laurentia , Lazenby Audrey J. 
Published: February 2021

Abstract
In this report, we describe a 36-year-old man with the synchronous occurrence of multiple gastric gastrointestinal stromal tumors and multiple intestinal lipomas. Multiple, small, and well-circumscribed gastric gastrointestinal stromal tumors (3 mm to 2 cm) were present within the gastrectomy specimen. The gastrointestinal stromal tumors were composed of epithelioid cells that were strongly positive for CD117 but negative for S100 protein or smooth muscle–specific actin. Also, 17 small submucosal lipomas were identified in the duodenal portion of the gastrectomy specimen. Endoscopic follow-up of the patient revealed more than 20 additional lipomas scattered throughout the intestine. Several large intestinal lipomas were resected endoscopically and histologically confirmed. Although both multicentric gastrointestinal stromal tumor and gastrointestinal lipomatosis have been reported in association with a few genetic syndromes, there has been no report, to our knowledge, of their coexistence. We feel that the coexistence of multiple lesions of these 2 rare diseases in this relatively young patient may represent a novel syndrome.
Resolution of Giant Cell Myocarditis After Extended Ventricular Assistance
Authors: Eid Shaker M. , Schamp David , Halushka Marc K. , Barouch Lili A. 
Published: February 2021

Abstract
Lower recurrence rates and improved long-term outcomes are the goal of treatment for giant cell myocarditis (GCM). We describe a case of GCM in an Asian woman who presented with new onset palpitations and syncope. She initially had normal systolic function by echocardiography with magnetic resonance imaging evidence of infiltrative cardiomyopathy. She underwent implantation of a biventricular assist device (BiVAD) because of rapidly deteriorating hemodynamic status. Giant cell myocarditis was diagnosed at that time by surgical biopsy. She was not treated with immunosuppressive therapy because of low likelihood of recovery and concerns for potential infection with the BiVAD in place. She received a heart transplant 12 months later and had extensive fibrosis but no evidence of active GCM in the heart explant. The role of extended BiVAD support in patients with GCM should be further investigated.

Published: February 2021

AbstractContext.—Automatic failure in gynecologic cytology proficiency testing occurs when a high-grade lesion or carcinoma (HSIL+, Category D) is misinterpreted as negative for intraepithelial lesion or malignancy (Category B).Objectives.—To document the automatic failure rate in 2006 and 2007 from the College of American Pathologists proficiency testing program (PAP PT) and compare them to projected values from 2004.Design.—Identify automatic failures from PAP PT in 2006 and 2007 and compare the rates of failure regarding participant and preparation type to validated slides in the College of American Pathologists Interlaboratory Comparison Program in 2004.Results.—There were 65 264 participant responses for HSIL+ slides included in this analysis from 2006 and 2007. Overall, 1% (666 of 65 264) of the HSIL+ responses were classified as negative, resulting in automatic failure for the participant. There were significantly fewer automatic failures in 2007 as compared with either 2006 or projected from 2004 data (P &lt; .001). Conventional preparations had a lower automatic failure rate than liquid-based preparations but only for 2006. Both pathologists and cytotechnologists interpreting liquid-based preparations faired better than projected from 2004 data.Conclusions.—The automatic failure rate in PAP PT is lower than expected based on 2004 data from the College of American Pathologists Interlaboratory Comparison Program. Automatic failures are a relatively small component (1% or less) of proficiency testing failures. The rate of automatic failure decreased from 2006 to 2007 and may be due to loss of poor performers in the testing pool, the test-taking environment, or removal of less robust slides from the program.
Carcinoma of the Breast With Medullary-like Features: Diagnostic Challenges and Relationship With BRCA1 and EZH2 Functions
Authors: Kleer Celina G. 
Published: February 2021

Abstract
This case presentation reviews the histologic distinction between pure medullary carcinoma and breast carcinomas with medullary-like features. This particular case prompts us to analyze the relationship among medullary carcinoma, basal-like breast carcinomas and carcinomas associated with germline BRCA1 mutations. In addition to now well-defined features, such as expression of high-molecular-weight cytokeratins and EGFR (epidermal growth factor receptor), basal-like tumors have a deficiency or dysfunction of BRCA1. This association in part explains the histologic features of BRCA1-associated breast cancers. Recent studies in our laboratory demonstrate that BRCA1 protein is regulated by a recently described gene, EZH2. These concepts illustrate the important relationships among histopathologic features; genomic profile; single gene abnormalities, such as BRCA1 and EZH2; and growth regulation in this subset of breast carcinomas.
Mitotic Index of Invasive Breast Carcinoma
Authors: Meyer John S. , Cosatto Eric , Graf Hans Peter 
Published: February 2021

Abstract
Context.—Mitotic figure counts are related to breast cancer behavior but have not been sufficiently reproducible to be accepted for clinical decision-making.
Objective.—To improve reproducibility and accuracy of the mitotic count.
Design.—Mitotic index (MI) was defined as the mitotic cell count per 10 high-power fields (HPFs), an area 0.183 mm2. Two to 6 replicate sets of 10 HPFs were counted from 328 invasive breast carcinomas. Standard errors and coefficients of variation for mean MI were compared with expected results predicted by the binomial distribution.
Results.—The boundaries for MI that separated the data into equal thirds (tertials) were 1.14 and 5.33. Standard errors and coefficients of variation for MI followed distributions predicted by binomial probability. Mean coefficient of variation was 147% for the low tertial, 72% for the midtertial, and 34.6% for the upper tertial.
Conclusions.—Standard errors for MI based on a single count of 10 HPFs are too broad and coefficients of variation too large to be acceptable for clinical use. This is explained as a binomial probability effect, possibly with a contribution from tumor heterogeneity. Errors can be reduced in proportion to the square root of the number of sets of 10 HPFs counted. Tertial cutoffs of MI of the Nottingham system currently used in breast carcinoma grading are too high to be applicable to the population we studied. We recommend validation of cutoffs before they are applied to a particular population of breast carcinomas. Counting 5 sets of 10 HPFs is necessary to accurately rank carcinomas with low MIs.
