Abstract During the primary well cementing operation, when the cement slurry is pumped into the annulus around the outside of the casing string, it is very critical not to over displace and let the displacement fluid enter the annulus. Traditionally, to determine when to stop the cement displacement operation, the top cement plug position is tracked volumetrically by dividing the displaced volume by the casing internal cross-sectional area. However, the volumetric method is prone to uncertainties related to displacement fluid compressibility, high-pressure pump inefficiency, flowmeter inaccuracy, and variance in casing joint diameters. The new cost-effective cement displacement monitoring method is based on the analysis of the pressure pulses generated by the top cement plug passing the casing. These pressure pulses are detected by the standard pressure transducer installed at the cementing head. When correlated with the casing tally, these pulses identify the plug position related to the completion elements that provide better accuracy than the volumetric method used conventionally. The case studies include the successful cement displacement monitoring example and the case where the plug was prematurely stopped 90 meters above the landing collar, which was revealed by the subsequent drilling and confirmed independently by the new plug tracking method.

Abstract Background Application of advanced body composition measurement methods is not practical in developing countries context due to cost and unavailability of facilities. This study generated ethnic specific body fat percent prediction equation for Ethiopian adults using appropriate data. Methods A cross-sectional study was carried ifrom February to April 2015 among 704 randomly selected adult employees of Jimma University. Ethnic specific Ethiopian body fat percent (BF%) prediction equation was developed using a multivariable linear regression model with measured BF% as dependent variable and age, sex, and body mass index as predictor variables. Agreement between fat percent measured using air displacement plethysmography and body fat percent estimated using Caucasian prediction equations was determined using Bland Altman plot. Results Comparison of ADP measured and predicted BF% showed that Caucasian prediction equation underestimated body fat percent among Ethiopian adults by 6.78% (P < 0.0001). This finding is consistent across all age groups and ethnicities in both sexes. Bland Altman plot did not show agreement between ADP and Caucasian prediction equation (mean difference = 6.7825) and some of the points are outside 95% confidence interval. The caucasian prediction equation significantly underestimates body fat percent in Ethiopian adults, which is consistent across all ethnic groups in the sample. The study developed Ethnic specific BF% prediction equations for Ethiopian adults. Conclusion The Caucasian prediction equation significantly underestimates body fat percent among Ethiopian adults regardless of ethnicity. Ethiopian ethnic-specific prediction equation can be used as a very simple, cheap, and cost-effective alternative for estimating body fat percent among Ethiopian adults for health care provision in the prevention of obesity and related morbidities and for research purposes.

BACKGROUND Telemedicine is utilized to deliver health care services remotely. Recently, it is well established due to pandemics because it can help the patients get required supportive care while minimizing their hospital exposure. In the future, it will continue to be used as a convenient, cost-effective patient care modality. OBJECTIVE The objectives were to identify physicians' challenges during teleconsultations and recognize the opportunities and strengths of this modality during the pandemic in a lower-income country. METHODS This cross-sectional study was conducted in a tertiary care hospital. The self-made questionnaire was filled through an online medium and responses were recorded on a five-point Likert scale. RESULTS A total of 83 participants were enrolled in this study. Most of them were Associate professors (29.8%), Assistant professors (26.2%), the ratio of the females was (52.4%) greater than males (,47.6%). 46 (54.8%) have laid between the age group 30-40 years. Pediatricians and senior instructors faced more difficulty in using telemedicine. The ones having clinical experience of fewer than 15 years or categorized in the age of 50-60 years faced challenges while using this modality. CONCLUSIONS During the current pandemic, situation telemedicine is the only glimmer of light to provide better quality health care. Telemedicine is an innovative strategy and it is important to understand the perception of physicians about it. Incomplete and inadequate infrastructure and attitude of the physicians is the main obstacle toward successful implementation of telemedicine. Successful installation and deployment of this technology require a complete grasp of the process among physicians.

Introduction/Aims Focused antenatal care provides individualised counselling, targeted assessment and safe, cost effective, evidence-based intervention. It has been implemented in developing countries as a strategy to improve maternal health. This study aimed to investigate sociodemographic factors associated with maternal complications in selected public county hospitals in Nairobi City County, Kenya. Methods This was a cross-sectional study using a sample of 397 postnatal women who were given a questionnaire, with sections on their sociodemographic and health characteristics. Data analysis was done using the Chi Square test to determine the association between study variables, with P<0.05 considered statistically significant. Results The study found that 30% of respondents reported a maternal complication during their current delivery outcome. Sociodemographic factors significantly associated with maternal complications were age (P=0.002), occupation (P=0.001) and income (P=0.011). The health factors associated with occurrence of maternal complications were number of deliveries (P=0.001) and mode of delivery (P=0.001). Conclusions A number of factors were found to be significantly associated with maternal outcomes, including age and occupation. Further studies to determine why young women do not use focused antenatal care are necessary, as this would help reduce the incidence of birth-associated complications.

Background. Although physical activity (PA) is a noninvasive and cost-effective method of improving the quality of health, global statistics show that only a few middle-aged and older adults engage in the recommended PAs. This is due to a lack of motivation and companionship. Objective. This study analyses the attitudes and self-determined motivation of Chinese middle-aged and older adults for PAs and their eagerness to participate in PAs such as sports, exercise, and recreational and cultural activities (RCAs), from attitudinal, eagerness, and motivational objectives of PAs perspective. Methods. A cross-sectional study was carried out on 840 middle-aged (35–54 years) and older adults (55+ years). To determine their attitude, eagerness, and self-determined motivation for PA, we used attitudinal, Eagerness for Physical Activity Scale (EPAS), and Situational Motivational Scale (SIMS). The data were analyzed with SPSS 23.0. Results. The results show that 39.1% of the participants were not satisfied with PAs. Compared with females, males reported a less positive attitude towards PAs. Moreover, a positive attitude decreases with age. Participants’ motivation and eagerness in activities such as RCAs, exercise, and sports are decreasing. Regarding self-determined motivation, there are gender differences in RCAs, but there is none for exercise and sports participation. Conclusion. The findings show the importance of RCAs and the support of family and friends enhancing the eagerness, attitude, and motivation to participate in PAs. Furthermore, the findings can help to create more effective PA programs for middle-aged and older adults. By engaging in RCAs, participants can reap the benefits of PAs. Participating in RCAs can lead to social equity in health.

Introduction: Primary Central Nervous System (CNS) tumours constitute less than 2% of overall cancers in adults and are the second most frequently encountered tumours in children. Meningiomas form 24-30% of primary intracranial tumours. Most intrinsic brain tumours are soft and gelatinous in consistency, smear preparation can readily made which gives excellent cytological details when compared to frozen section as the latter produces ice crystal artifacts. Aim: To assess the diagnostic utility of squash cytological evaluation of meningiomas and its comparison with final histopathological diagnosis. Materials and Methods: The cross-sectional study was done at Thanjavur Medical College, Thanjavur, Tamil Nadu, India for period of three years from January 2015 to December 2017. Total of 54 clinically diagnosed and radiologically suspected case of meningiomas were selected. Smears were prepared from the biopsy samples sent in normal saline and stained by Haematoxylin and Eosin (H&E) method. The cytological features were noted and matched with biopsy findings. Descriptive statistics were used to analyse the results. Results: Total of 54 squash smears with male to female ratio was 1:1.5. Maximum number of cases were seen between 41- 50 years followed by 51-60 years. Complete concordance was obtained in 51 cases (94.44%) and partial concordance was noted in a case due to underestimation of malignancy grade in squash cytology. Out of 54 cases, two cases were found to be discordant with final histopathological diagnosis. Conclusion: Intraoperative squash cytology is easy, rapid, reliable and cost-effective technique for neurosurgical consultation with fairly high accuracy in diagnosing meningiomas.

BACKGROUND Multimorbidity is becoming increasingly common and is a leading challenge currently faced by societies with aging populations. The presence of multimorbidity requires patients to coordinate, understand, and use the information obtained from different health care professionals, while simultaneously striving to distinguish the symptoms of different diseases and self-manage their sometimes conflicting health problems. Electronic health (eHealth) tools provide a means to disseminate health information and education for both patients and health professionals and hold promise for more efficient and cost-effective care processes. OBJECTIVE The aim of this study was to analyze the use of eHealth tools, taking into account the citizens’ sociodemographic and clinical characteristics, and above all, the presence of multimorbidity. METHODS Cross-sectional and exploratory research was conducted using online survey data from July 2011 to August 2011. Participants included a total of 14,000 citizens from 14 European countries aged 16 to 74 years, who had used an eHealth tool in the past 3 months. The variables studied were sociodemographic variables of the participants, the questionnaire items assessing the frequency of using eHealth tools, the degree of morbidity, and the eHealth adoption gradient. Chi-square tests were conducted to examine the relationship between the sociodemographic and clinical variables of participants and the group the participants were assigned to according to their frequency of eHealth use (eHealth user group). A one-way analysis of variance (ANOVA) allowed for assessing the differences in the eHealth adoption gradient average between different groups of individuals according to their morbidity level. A two-way between-groups ANOVA was performed to explore the effects of multimorbidity and age group on the eHealth adoption gradient. RESULTS According to the eHealth adoption gradient, most participants (68.15%, 9541/14,000) were labeled as rare users, with the majority of them (55.1%, 508/921) being in the age range of 25 to 54 years, with upper secondary education (50.3%, 464/921), currently employed (49.3%, 454/921), and living in medium-sized cities (40.7%, 375/921). Results of the one-way ANOVA showed that the number of health problems significantly affected the use of eHealth tools (F2,13996=11.584; P<.001). The two-way ANOVA demonstrated that there was a statistically significant interaction between the effects of age and number of health problems on the eHealth adoption gradient (F4,11991=7.936; P<.001). CONCLUSIONS The eHealth adoption gradient has proven to be a reliable way to measure different aspects of eHealth use. Multimorbidity is associated with a more intense use of eHealth, with younger Internet users using new technologies for health purposes more frequently than older groups with the same level of morbidity. These findings suggest the need to consider different strategies aimed at making eHealth tools more sensitive to the characteristics of older populations to reduce digital disadvantages.

Background: Despite the insupportable burden caused by the human papillomavirus (HPV) and high vaccine acceptability, vaccination programs are not currently available for men who have sex with men (MSM). We aimed to assess HPV infection by examining the willingness for vaccination among MSM and cost-effectiveness of the Chinese 2-valent HPV vaccine.Methods: We recruited MSM in Shenyang, China between July and December 2020 to conduct anal HPV testing and an online survey regarding HPV-related knowledge and vaccine acceptability. We performed a cost-effectiveness analysis to evaluate the incremental cost-effectiveness ratios (ICERs) of the Chinese 2-valent HPV vaccine.Results: A total of 234 participants completed the online survey; of those, 203 were successfully tested for HPV. The median age was 30 years [interquartile range (IQR): 23–38 years]. Most participants had at least undergraduate education (136/234, 58.1%). The acceptability rate for the free HPV vaccine was 57.7% (135/234). The prevalence of HPV types 16 and 18 was 14.9% (18/121) and 26.8% (22/82) in the willing and unwilling to vaccinate groups, respectively (P &gt; 0.05). The prevalence of high-risk HPV among participants aged &lt;30 and ≥50 years was 48.6 and 38.9%, respectively. Using the Chinese per capita gross domestic product (GDP) as a threshold, the Chinese 2-valent HPV vaccine would be a “very cost-effective” strategy, with an ICER value of USD 4,411. This evidence showed that the Chinese 2-valent HPV vaccine was more cost-effective than other imported vaccines.Conclusions: Targeted strategies should be utilized in MSM with different rates of vaccine acceptability. A pilot HPV vaccination program based on the Chinese 2-valent HPV vaccine for MSM is urgently warranted to reduce the burden of HPV and anal cancer.

Reflection Of Light

Background: The Red Reflex is described as the red to orange reflection of light from the fundus of the eye, observed while using a retinoscope or an ophthalmoscope. Red Eye Reflex Test is determined by the optical media transparency which includes vitreous humor, aqueous humor, cornea and tear film and reflection of light from the  back of the eye (fundus) through optical media and into the aperture of the ophthalmoscope. Factors that will block or impede the passage of light through this transparent media or affects its reflection back from fundus will produce an abnormal Red Eye Reflex. Red Eye Reflex (RER) testing is important & effective tool for early detection of ocular abnormalities such as retinal abnormalities, cataract, retinoblastoma and glaucoma. Red reflex is cost effective, can be performed very easily, requires minimal setting, can screen important ocular abnormalities and facilitate their early detection with prompt intervention to prevent long term sequelae associated with the disease. Aim: To find out the diagnostic accuracy of Red Reflex test for diagnosing ocular abnormalities in newborns. Methodology: Ours will be a prospective cross-sectional study where RER examination will be performed within one week of birth of a newborn in a darkened and will correlate the examination findings with respect to ocular findings determined by ophthalmologist to determine its efficacy, sensitivity and specificity in detecting neonatal ocular abnormalities. Expected results: After completion of the study we will be able to determine the accuracy of RRT for ocular abnormality detection in the neonates. We will be able to determine the sensitivity, specificity, PPV & NPV of the red reflex test. If the specificity and the sensitivity is good then we can use RRT as a routine screening method for detection of intraocular abnormalities. Conclusion: To find the Red reflex Test efficacy in screening of the ocular abnormalities in the new born.
