Factors Influencing Security Incidents on Personal Computing Devices
Authors: Hewitt Barbara , White Garry
Published: June 2021

Organizations expect their employees to connect securely to the organization's computer systems. Often these employees use their personal computers to access the organization's networks. This research explores whether these same employees apply protective security measures to their personal computers. Perhaps these employees behave riskily based on their optimistic bias. Results indicate that while cyber optimistic bias and perceived vulnerability influence individuals to apply more protective security measures, the users still experienced security incidents. Thus, organization are vulnerable to cyber-attacks if they are allowing employees to use personal computers to access these databases.
Evaluation of Tourism E-Commerce User Satisfaction
Authors: Tang Guanghai , Zeng Hui
Published: June 2021

According to the UNWTO, within 4 to 5 years, the proportion of tourism e-commerce in e-commerce will reach 20%-25%. The purpose of this paper is to improve the inadequacy of tourism e-commerce in customer experience, to conduct customer e-commerce satisfaction surveys, and to draw customers' dissatisfaction with tourism e-commerce. The experimental results show that the overall customer satisfaction is 2.6128. According to the division of the scale vector, the overall satisfaction of the travel e-commerce customers is generally level. The first-level fuzzy comprehensive evaluation is 0.0967, 0.1696, 0.3366, 0.2469, 0.502. According to the principle of maximum membership degree, the evaluation grades of R3 and R5 in the first-level fuzzy comprehensive evaluation are “unsatisfactory,” that is, the tourism-supporting services and contract-performance services become the main factors affecting customer satisfaction. In order to improve customer satisfaction, the tourism e-commerce platform should strengthen the management of tourism-supporting services and contract-fulfillment services.
Integrating Palliative Care Into Heart Failure Management
Authors: Bierle Rebecca (Schuetz) , Vuckovic Karen M. , Ryan Catherine J.
Published: June 2021

Background

The World Health Organization defines palliative care as an approach that improves the quality of life of patients and their families through the prevention and relief of suffering by assessment and treatment of physical, psychosocial, and spiritual problems. Any patient with chronic debilitating disease, including heart failure, is a candidate for interdisciplinary palliative care to manage their complex physical and psychosocial needs.

Clinical Relevance

The philosophy of palliative care has evolved to include a vision of holistic care extended to all individuals with serious illness and their families or caregivers that should be integrated throughout the continuum of care, including the acute phase. The critical care nurse will likely encounter patients with heart failure who are receiving or are eligible to receive palliative care at various time points during their illness. Critical care nurses therefore play a pivotal role in symptom palliation affecting the heart failure patient’s quality of life.

Purpose

To review the models of palliative care and the role that the critical care nurse plays in symptom palliation and preparation of the patient and their family for transition to other levels and settings of care.

Content Covered

This review addresses the principles and models of palliative care along with how to integrate these principles into all phases of the heart failure disease continuum. Also included are recommendations for palliation of symptoms specific to heart failure patients as well as a discussion of the role of the critical care nurse and the importance of shared decision-making.
Condom-Use Negotiation, Alcohol Consumption, and Hiv-Risk Sexual Behavior among Female Sex Workers in Kupang, East Nusa Tenggara, Indonesia: A Cross-Sectional Study
Authors: Khumaidi  , Yona Sri , Waluyo Agung
Published: June 2021

Background

Female Sex Workers (FSW) play a crucial part in HIV transmission. Having unprotective condom during sexual activity can lead to HIV infection. Having lower power in condom negotiation with client can lead FSW not to using condoms during the sexual act. Alcohol consumption was also mediated HIV risk behavior among FSW. This study aimed to evaluate the relationship between condom use-negotiation, alcohol consumption and HIV-risk sexual behavior among female sex workers (FSW) in Kupang.

Design and Methods

A cross-sectional study was conducted with 125 FSWs aged 18 to 60 years recruited from Yayasan Tanpa Batas Kupang with consecutive sampling. The data were analyzed using univariate and the Chi-square test.

Results

The majority of FSWs (61.6%) reported had low negotiation condom use with their clients, about 77.6% reported high levels of alcohol consumption and 64.8% had high-risk sexual behavior. Condom-use negotiation (p-value: 0.003) and alcohol consumption (p-value: 0.037) were found to be significantly associated with HIV-risk sexual behavior.

Conclusions

Future interventions on HIV prevention should focus on empowering young FSWs with condom negotation skills in order to increase condum use. It is also recommended to include information about alcohol consumption and it's relationship wit HIV-risk behavior in order to have better health outcomes for FSW.

Authors: Yunita Dwi Kartika , Budiati Tri
Published: June 2021

Background

Exclusive breastfeeding is influenced by several things, including the mother's motivation and supporting factors such as husband’ support. Exclusive breastfeeding and duration of breastfeeding may relate to nutritional status of infants considering the effects that malnutrition may have. The purpose of this study is to identify the effects the duration of breastfeeding and partner support for breastfeeding mothers on the nutritional status of infants aged 0–6 months in the village of Tanjung Pauh, West Sumatera, Indonesia.

Design and Methods

This study used a quantitative study in which a cross-sectional method. Data collection was carried out using an online questionnaire distributed to the 76 breastfeeding mothers were conducted by consecutive sampling at Tanjung Pauh. Chi-square test analysis was used to determine the association between the duration of breastfeeding and partner support with the nutritional status of infants.

Results

There was not a significant relationship found between the duration of breastfeeding p=0.216, α=0.05, p>α), and partner support for breastfeeding mothers with the nutritional status of infants aged 0–6 months in the village of Tanjung Pauh, West Sumatera (p=0.100, α=0.05, p>α).

Conclusions

In Tanjung Pauh, partner support is not a factor that affects the nutritional status of infants aged 0–6 months, which may be due to the positive attitude of breastfeeding mothers toward fulfilling their babies’ nutritional requirements so as to achieve a normal nutritional status.

Authors: Susilowati Maelani , Afiyanti Yati
Published: June 2021

Background

Breast cancer is one of the major cancer types found among Indonesian women. This cancer diagnosis and its treatment causes perpetual financial burden for the women and their family. This study aims to identify the correlation between socio-demographics with financial toxicity among women with breast cancer in Indonesia.

Design and methods

This study design was cross-sectional with 109 respondents of Indonesian breast cancer survivors who were recruited using consecutive sampling. Quantitative data were collected with a demographic and a Comprehensive Score for Financial Toxicity (COST) questionnaires, then analyzed using Chi-Square test and linear regression method.

Results

The majority of the women were 18 to 55-years-old (75.2%), married (91.7%), employed (80.7%), and having moderate income (58.7%). Logistic regression analysis indicates that survivor's family as a primary wage earner (p=0.042), low-high income (p=0.043), and dependents number (p=0.012) are significantly associated with financial toxicity.

Conclusions

The financial toxicity among women with breast cancer was mainly correlated with the number of survivor's dependent and the household income. This study encourage related parties to establish socio-economic safety net for women with breast cancer, including their families.

Authors: Malik Rani , Dhillon Harpreet Singh , Sahu Vinod Kumar , Sasidharan Shibu , Dhillon Gurpreet Kaur
Published: June 2021

Background:

Alcohol withdrawal syndrome is a potentially life-threatening condition with severe complications such as withdrawal seizures and delirium tremens. A valid and reliable biomarker for predicting the severity of alcohol withdrawal can be instrumental in individualizing effective therapy at the earliest.

Methodology:

This was an observational study done on 120 patients to study the relationship between serum creatine phosphokinase (CPK) levels with severity of alcohol withdrawal. The assessment for the severity of alcohol withdrawal was done with Clinical Institute Withdrawal Assessment for Alcohol-revised (CIWA-Ar) scale and an association was studied between the serum CPK levels and the severity of alcohol withdrawal. The data was analyzed using Chi-square test and Kruskal–Wallis tests.

Results:

The severity of alcohol withdrawal as per the CIWA was 26.66% mild, 55% moderate, and 18.33% severe. The mean serum CPK level for mild withdrawal was 126.93 IU/L, moderate withdrawal was 303.66 IU/L, and for severe withdrawal was 780.81 IU/L. A statistically significant association was obtained indicating that patients with higher CIWA-Ar scores are likely to have a higher level of serum CPK levels.

Conclusion:

Serum CPK levels were significantly associated with severity of alcohol withdrawal and can possibly serve as a candidate biomarker.

Authors: Dandey Adarsh , Pal Ajay Kumar , Agrawal Manish , Kumar Awanish , Anand Akshay , Pahwa Harvinder Singh , Singh Krishna Kant , Sonkar Abhinav Arun
Published: May 2021

PURPOSE:

Inguinal hernia repair is the most commonly performed surgery worldwide with surgical approaches being open and endoscopic hernioplasty. Mesh fixation in endoscopic hernia repair still remains a topic of debate. Moreover, a paucity of literature is present with regard to the quality of life (QOL) outcomes after mesh fixation in endoscopic hernia repair.

MATERIALS AND METHODS:

This prospective nonrandomized study was done on patients operated by totally extraperitoneal (TEP) hernioplasty. Primary outcome parameters included any complications, postoperative pain, and hernia-related QOL by Carolina's Comfort Scale among two different types of mesh fixation techniques (Group I - intracorporeal Suture fixation and Group II - tack fixation).

RESULTS:

TEP repair was done on 74 patients with suture fixation of the mesh by intracorporeal knotting (Group I; n = 30) and tack fixation of mesh (Group II; n = 44). There was no significant difference in the time to return to routine work, sensation of mesh, and pain, but time to return to office work was significantly lower in the patients of Group I (4.29 ± 0.99) compared to Group II (4.75 ± 0.96) and there was a significant difference in movement limitation from postoperative to subsequent time period in all groups except for after 3 months to 6 months in Group II.

CONCLUSION:

Intracorporeal suture fixation of mesh in TEP can be used as an alternate technique for mesh fixation with comparable perioperative and QOL outcomes.
Dynamic Inguinal Ultrasound (DIUS) in diagnosing groin hernias
Authors: Niebuhr Henning , Malaibari Zaid , Dag Halil , Reinpold Wolfgang , Köckerling Ferdinand
Published: May 2021

Groin hernia is one of the most common surgical conditions worldwide. Clinical examination can reveal the majority of inguinal hernias. Small inguinal and femoral hernias (in women) may be missed. Dynamic inguinal ultrasound (DIUS) can fill this diagnostic gap. A standardized technique of DIUS is, therefore, important and will be described. The results show high specificity (0.9980) and sensitivity (0.9758), demonstrating the value of the method (which is known to be highly examiner dependent).

Authors: Chukwuka Lucy Omonon , Olorunfemi Olaolorunpo , Okanlawon Funmilayo , Osunde Ngozi Rosemary , Ogunniran Abiodun A.
Published: May 2021

Background:

In Nigeria, approximately 80% of women who develop cervical cancer (CC) die annually from the disease. In Benin City, it is the most common type of cancer, accounting for 74.6% of gynecological admissions. The high incidence and death rate of CC are attributable to a lack of knowledge of the disease. Consequently, this study aims to determine the effects of information, education, and communication (IEC) as a strategy for enhancing CC knowledge among women.

Materials and Methods:

This quasi-experimental study utilized a multi-stage sampling procedure. First, Egor Local Government Area (LGA) was selected out of five LGAs in Benin City by balloting. Second, two health centers, Egor and Evbuotubu, were randomly assigned to the experimental group (EG) and control group (CG), respectively. Third, 200 participants per group were selected using a systematic sampling technique. Data were analyzed using descriptive statistics, Chi-square, logistic regression, and repeated analysis of variance at α 0.05.

Results:

The mean ages of the participants were 38.4 ± 8.0 (EG) and 34.5 ± 8.0 (CG) years. There were no significant differences in age (P = 0.17), educational status (P = 0.18), and occupation (P = 0.43) between the two groups. The participants' knowledge at P1 for the EG (6.3 ± 4.6) was comparable with the CG (8.3 ± 5.4). At P2 and P3, knowledge scores increased significantly in the EG (17.9 ± 2.2; 15.4 ± 3.2, respectively) compared with the CG (8.5 ± 4.9; 8.4 ± 5.4, respectively). Comparisons of P1, P2, and P3 in the EG revealed significant differences in mean scores.

Conclusion:

An IEC strategy increased knowledge of CC. Therefore, we strongly recommend integrating this approach into public health education strategies for women at primary and secondary health-care centers.

Authors: Augustine Ndaimani , Philip Owiti , Kumar Ajay MV , Simukai Zizhou , Owen Mugurungi , Dumisani Mugauri Hamufare , Brian Komtenza
Published: May 2021

Introduction:

Prevention of mother-to-child transmission (PMTCT) is a key strategy for ending the human immunodeficiency virus (HIV) pandemic. Most studies have focused on the mothers' side of the PMTCT cascade or the rate of vertical HIV transmission. Information on child-focused cascade is limited. We aimed to evaluate HIV testing, antiretroviral therapy (ART), and cotrimoxazole prophylaxis uptake and associated factors among HIV-exposed infants (HEIs) born in 2017.

Methods:

This was a record-based descriptive study in Mashonaland East Province, Zimbabwe. We analyzed routinely collected program data abstracted from electronic and paper-based HEI registers. Uptakes were calculated as proportions while associations were measured using adjusted risk ratios (log-binomial regression).

Results:

Of 1028 HEIs, 1015 (98.7%) were commenced on nevirapine prophylaxis, while 915 (89.0%) were commenced on cotrimoxazole prophylaxis. A total of 880 (85.0%) HEIs were tested for HIV by 6 weeks and 445 (44.4%) by 9 months. Overall, 40 (3.9%) were found to be HIV positive, and of them, 34 (85.0%) commenced on ART. Secondary and tertiary health facilities, being born through nonvaginal delivery, and certain districts were significantly associated with not commencing cotrimoxazole prophylaxis or getting tested for HIV. One district was associated with less risk of not having an HIV test by 9 months.

Conclusions:

While nevirapine, cotrimoxazole, and ART uptake were high among the HEIs, HIV testing by 9 months was suboptimal. The vertical HIV transmission rate was 3.9%. There is a need to strengthen HIV testing and antiretroviral and cotrimoxazole prophylaxes, especially at high-level facilities and certain districts.

Vaccination in Controlling COVID Pandemic in India
Authors: Kushwaha Arvind Singh , Banerjee Sitikantha
Published: May 2021

The ongoing COVID-19 pandemic has been unstoppable across the globe and India. The application of strategy “test, track and treat” has not been sufficient in halting the pandemic. Arrival of vaccines on the horizon has raised hopes of termination of pandemic in the near future. It should be emphasized that epidemiological relevance, efficacy, safety, operational feasibility, and social acceptance are minimum prerequisites for successful implementation of a new vaccination campaign. The ambitious launch of COVID vaccination by India at the juncture of a declining pandemic needs to be discussed in relation to its timing, economic implications, and ramifications on public health. This article aims to analyze this vaccination strategy.

Published: May 2021

Purpose:

This multicentric questionnaire-based study was undertaken to address the lack of systematic background data on the knowledge, attitudes, and practices among Indian physicians related to antimicrobial use and resistance.

Materials and Methods:

A validated structured study questionnaire was used for capturing respondent particulars, antimicrobial prescribing habits, knowledge of antimicrobial resistance (AMR), ways of choosing and learning about antibiotics, agreement or disagreement with certain perceptions regarding antibiotics, selection of antibiotics in specific settings, and suggestions regarding rationalizing antimicrobial use in the practice setting. Summary statistical analysis of the pooled data was done.

Results:

Five hundred and six respondents with a mean (standard deviation) age of 31.4 (8.71) years participated in the study. Three hundred and twenty-seven were medical and 179 surgical discipline clinicians. Overall, the theoretical knowledge about antimicrobials was satisfactory, but areas of concern were noted in the attitude and practice domains. A substantial proportion of participants failed to identify the correct choice of antibiotics in the case-based scenarios. 38.33% reported not attending a single continuing medical education on antimicrobials during the past year. Statistically significant differences were not observed in the KAP quotient scores between medical and surgical discipline respondents.

Conclusions:

Despite satisfactory background knowledge regarding the rational use of antimicrobials and AMR patterns, there are discrepancies in the physicians’ prescribing attitude and thus strengthen the case for instituting specific interventions to improve antimicrobial prescribing.
Sarcomatoid urothelial carcinoma arising in the female urethral diverticulum
Authors: Park Heae Surng
Published: June 2021

A sarcomatoid variant of urothelial carcinoma in the female urethral diverticulum has not been reported previously. A 66-year-old woman suffering from dysuria presented with a huge urethral mass invading the urinary bladder and vagina. Histopathological examination of the resected specimen revealed predominantly undifferentiated pleomorphic sarcoma with sclerosis. Only a small portion of conventional urothelial carcinoma was identified around the urethral diverticulum, which contained glandular epithelium and villous adenoma. The patient showed rapid systemic recurrence and resistance to immune checkpoint inhibitor therapy despite high expression of programmed cell death ligand-1. We report the first case of urethral diverticular carcinoma with sarcomatoid features.
Socioeconomic status: a disease modifier of chronic rhinosinusitis?
Authors: Kilty Shaun J. , McDonald J. Ted , Johnson Stephanie , Al-Mutairi Dakhellallah
Published: June 2021

Introduction: The Lund-MacKay score (LMS) correlates poorly with chronic rhinosinusitis (CRS) symptom severity. Patients with CRS also tend to report relatively lower levels of mental wellbeing. Our purpose was to determine if there is a correlation between socio-economic status (SES) and CRS severity as measured by the LMS, and if there is an association between depression symptoms and the severity of CRS using the LMS. Methods: A total of 127 patients diagnosed with CRS were prospectively recruited and assessed with a sinonasal assessment questionnaire (SNAQ-11), and the Patient Health Questionnaire (PHQ-9) for depression. Each patient`s education level, family income, and smoking behavior were determined. The sinus CT scan was scored using the LMS. The data were analyzed using ordinary least squares (OLS) regression techniques. Results: Having a highschool education or less was associated with higher SNAQ-11 scores while being a daily smoker was associated with higher SNAQ-11 scores. There was no significant relationship between educational attainment, financial income or daily smoking and sinus CT score. Including depression scores in the SNAQ-11, regression equations indicated a significant and positive relationship between depression severity and SNAQ-11 score. CRS with polyps was negatively associated with SNAQ-11 scores but, as expected, it was positively associated with a higher LMS. Conclusions: Lower SES status is a negative modifying factor of subjective CRS severity but it has no impact on the LMS. Depression symptoms are associated with increased subjective CRS severity but they have no effect on the LMS. How SES and depression impact on a patient`s self-reported disease severity requires further study.
How we do it: mini posterior septal artery flap for coverage after transphenoidal approaches
Authors: Khetani J.D. , Micomonaco D.C. , Wright E.D.
Published: June 2021

We propose a novel posterior nasal flap for use in endoscopic approaches to the sella and parasellar region that involve resection of the sphenoid face and a posterior nasal septectomy. It involves elevation of the mucosa of the posterior septum and sphenoid face with preservation of the angiosome based on the posterior septal artery. This flap has the advantages of maximal mucosal preservation in order to optimize postoperative healing and has been demonstrated to permit future elevation of a complete naso-septal flap for reconstruction of anterior skull base defects. An illustration of the technique is provided.
Olfaction after endoscopic sinus surgery: long-term results
Authors: Briner H.R. , Jones N. , Simmen D.
Published: June 2021

Loss of olfactory function is one of the main symptoms in patients with chronic rhinosinusitis. This prospective, non-randomized interventional study reports five years results of olfaction of patients with chronic rhinosinusitis who underwent endoscopic sinus surgery in conjunction with topical medical treatment. Forty-five patients with chronic rhinosinusitis who underwent endoscopic sinus surgery were evaluated preoperatively, after three months and 34 (76%) of them after five years. Olfactory function was assessed by a subjective visual analogue scale, by a screening test of olfaction with Smell Diskettes and by measuring the N-Butanol threshold. Patient`s subjective sense of olfaction using a visual analogue scale was improved in 79% at 5 years. Objective measurements by Smell Diskettes improved in 53% at 5 years whilst the quantitative measurement by the N-Butanol threshold improved in 85% at 5 years. The high percentage of patients with improvement of olfaction five years after surgery indicates that endoscopic sinus surgery in conjunction with continued topical treatment leads to a long term improvement of the sense of smell. However, it was found that - measured by the sensitive N-Butanol threshold - up to 9% had no improvement and 6% had deterioration in their olfaction at 5 years after endoscopic sinus surgery. This fact has to be considered in the preoperative counselling of patients.
Numerical simulation of humidification and heating during inspiration within an adult nose
Authors: Sommer F. , Kroger R. , Lindemann J.
Published: June 2021

Background: The temperature of inhaled air is highly relevant for the humidification process. Narrow anatomical conditions limit possibilities for in vivo measurements. Numerical simulations offer a great potential to examine the function of the human nose. Objective: In the present study, the nasal humidification of inhaled air was simulated simultaneously with temperature distribution during a respiratory cycle. Methods: A realistic nose model based on a multislice CT scan was created. The simulation was performed by the Software Fluent(r). Boundary conditions were based on previous in vivo measurements. Inhaled air had a temperature of 20(deg)C and relative humidity of 30%. The wall temperature was assumed to be variable from 34(deg)C to 30(deg)C with constant humidity saturation of 100% during the respiratory cycle. Results: A substantial increase in temperature and humidity can be observed after passing the nasal valve area. Areas with high speed air flow, e.g. the space around the turbinates, show an intensive humidification and heating potential. Inspired air reaches 95% humidity and 28(deg)C within the nasopharynx. Conclusion: The human nose features an enormous humidification and heating capability. Warming and humidification are dependent on each other and show a similar spacial pattern. Concerning the climatisation function, the middle turbinate is of high importance. In contrast to in vivo measurements, numerical simulations can explore the impact of airflow distribution on nasal air conditioning. They are an effective method to investigate nasal pathologies and impacts of surgical procedures.
Advertising slogans in the gambling industry: content analysis informed by the heuristics and biases literature
Authors: Krawczyk Michał , Własiuk Łukasz
Published: May 2021

In this paper, we analyse the contents of over a thousand gambling slogans. We identify several features considered in the literature that the slogans might capitalize on. In particular, we investigate heuristics and biases analyzed in the behavioural economics of decision making under risk, such as the gambler’s fallacy. We then employ factor analysis to identify the main types of heuristics and biases showing up in the analyzed slogans. We find three naturally interpretable factors and show that they intuitively correlate with the type of game each slogan advertised. We also construct an index of potentially dangerous features a slogan might have and show that their use subsided slightly in the UK after the Industry Code for Socially Responsible Advertising was implemented in 2007.RésuméCet article porte sur l’analyse de plus d’un millier de slogans sur les jeux de hasard. Nous retrouvons dans ces slogans de nombreuses caractéristiques évoquées dans la littérature sur le sujet, en particulier les heuristiques et biais analysés en économie comportementale dans la prise de décision en situation de risque, comme l’illusion du joueur. Au moyen d’une analyse factorielle, nous dégageons les trois principaux types d’heuristiques et de biais qui se manifestent dans les slogans étudiés. Nous décelons ensuite trois facteurs interprétables et démontrons leurs corrélations intuitives avec le type de jeu dont chaque slogan fait la promotion. Enfin, nous proposons un index des caractéristiques potentiellement dangereuses des slogans sur les jeux de hasard et démontrons que l’emploi de ceux-ci a diminué légèrement au Royaume-Uni après l’adoption du Gambling Industry Code for Socially Responsible Advertising en 2007.

Published: May 2021

Background: Tetanus is a public health problem in Nigeria. This study examines the demographic and clinical profile of postneonatal tetanus (PNT) seen in University of Maiduguri Teaching Hospital (UMTH), North- eastern Nigeria.Methods: This is a hospital-based prospective study of PNT. All childrenbeyond the neonatal period to 14 years of age admitted into the Paediatrics unit of UMTH, Maiduguri from June 2009 to July2011 with the diagnosis of PNT were studied.Results: A total of 39 cases of PNT were admitted over the period underreview. The male: female ratio was 2.3:1.0. Their ages at presentationranged between 16 months and 14 years, with mean +SD of 6.9+3.87 years. Over 90 percent of the children were either not immunizedagainst tetanus or their immunization status was unknown and onlytwo of the children were fully immunized. No booster immunizationwas received by any of the eligible children. The portal of entry of the infection was injury to the lower limbs and otogenic route in 53.9% and 33.3% respectively. Majority of patients were of low socioeconomicstatus. The duration of hospital stay ranged between 1-50 days with mean + SD (18.68+ 11.51).The mortality rate was (7)18 %.Conclusion: Tetanus still remains a major cause of childhood morbidityand mortality in Nigeria. Severe disease and the first one week of admission are the main variables identified to influence outcome.Therefore, there is need to strengthen routine immunization and booster doses of tetanus toxoid (TT) should be mandatory at primary and secondary school entry. Close monitoring of patients with severe tetanus during the critical period is imperative for successful management.

Published: May 2021

In Nigeria, Dettol® Antiseptic Solution poisoning is an uncommon occurrence in all age groups. In a registered child specialist clinic in Kano, a three – day old neonate presented with clinical features believed initially to be due to neonatal seizures and sepsis, but which turned out to be due to non-accidental dettol® poisoning by a single mother who contaminated the glucose D granules that was meant to supplement baby’s feed. Greater vigilance on single mothers and coordinated services to single mothers is highly advocated to improve maternal – infant bonding and hence reduce infanticidal ideas.Key words: Dettol® Poisoning, Neonate, socially disadvantaged mother, child abuse

Symptomatic subdural haematoma (SDH) in term infants typically occur following traumatic vaginal delivery. Emergency Caesarean Section (EmC/S) carried out after failed attempts at vaginal delivery may also be complicated by symptomatic SDH but spontaneous symptomatic SDH complicating Elective Caesarean Section (ElC/S) is a rarity. We describe a case of massive SDH in a term baby delivered by Elective C/S in the absence of risk factors for intracranial haemorrhage. The aim of this presentation is to highlight the significance of acute subdural haematoma in the diagnostic work up of neonates presenting with acute neurologic symptoms in the absence of traumatic delivery.Key words: Symptomatic subdural haematoma, Caesarean section, severe birth injuries, neonatal seizure

Authors: Uleanya ND , Obidike EO
Published: May 2021

Background: Hepatitis B Virus (HBV) infection has reached pandemic proportions all over the world with areas of highest prevalence being the sub- Saharan Africa and Southeast Asia. Most deaths related to HBV are due to complications from chronic infection. Acquisition of infection at a younger age is the most important predictor of chronicity. Eradication of HBV is an important but difficult tasks facing public health. HB immunization is the single most important factor in hepatitis B control and was commenced in 2004 in Nigeria.Objectives: To determine the prevalence of Hepatitis B surface antigen (HBsAg) among children in the era of HB immunization, the risk factors of transmission and knowledge of mothers about their HB status.Methods: A cross sectional study carried out on one hundred and forty children aged 18 months to 15 years at the children outpatient clinic (CHOP) of the University of Nigeria Teaching Hospital, Ituku. Hepatitis B surface antigen (HBsAg) was determined using Determine Test Kits and a structured interviewer administered questionnaire administered.Results: Six were positive for HBsAg, giving a prevalence rate of 4.3%. HBsAg was least prevalent among children 1-5 years (2%). None of the children ≤ 5 years who received HB vaccination was positive for HBsAg though one child > 5 years who received the vaccine was positive. Sharing of toothbrushes among siblings was found to be a significantly associated risk factor. Only 6.4% of mothers knew their hepatitis B status.Conclusion: There is a gradual fall in the prevalence of HBsAg in our environment due to HB immunization. Sharing of toothbrushes may be a potent means of transmission of HBV infection.Keywords: HBV, Prevalence, Children, Transmission, HB immunization

Published: May 2021

Background: Intestinal parasitic infection is highly prevalent among children in the tropics. Identifying the most at risk group and subsequent targeted intervention will lead to cost effective and easy to implement control programme. We thus aim to determine the prevalence and pattern of intestinal parasite among pupils from public and private schools.Material and Method: This was a cross-sectional survey. Participants were recruited through multistage stratified random sampling. Information were collected using a questionnaire and early morning freshly passed stool sample was collected and processed from each participating pupil. Stool microscopy was done using saline and iodine preparations. Eggs were counted using Stoll’s method. Data obtained was analyzed using EPI INFO version 3.5.1.Results: Four hundred and twenty  pupils were studied, 210 pupils from each school type. Prevalence of 78.1% and 17.1% were recorded for the public and private schools respectively. The pupils from the public schools were 17.23 times more likely to have intestinal parasitic infestation compared to those from private schools (OR =17.23, 95% CI = 10.6-28.01, p = <0.0001). Ascaris lumbricoides was the most frequent isolate in both the public (62.8%) and private (66.7%) schools. The prevalence of multiple parasitic infestation was 14.8% in the public schools and none in the private schools. Socioeconomic status and source of water were the main factors with significant effect on the prevalence of intestinal parasite (p<0.0001).Conclusion: Intestinal parasitic infestation remains a very common health issue among the children particularly in the public schools. Distribution of free antiparasitic drugs to pupils at the beginning of every term should be incorporated into the school health program.Key words: Intestinal Parasites, Ascaris lumbricoides, public school, private school, socioeconomic status.

Background: Contemporary understanding of the pattern of congenital anomalies is both important in its clinical management as well as in improving the overall health of the community.Methodology: All infants presenting from January to December 2102 at the centre were prospectively studied.Results: A total of 5010 infants were screened, of which 108 have congenital anomalies giving a prevalence of 2.2%. Major anomalies were noted in 101 (93.5%) infants. Only two (1.9%) were preterm. Consanguineous relationship was observed in 2 (1.9%) cases. Pre natal Ultrasound scan was done in 33(30.8%), but in only 7 (6.5%) was any anomaly detected Onitsha, a densely populated urban area contributed 45(42%) of the cases. Only 7(6.5%) of the mothers took herbal prescriptions in the first trimester of pregnancy. Risk of anomaly progressively rises, reaching a peak of 48% in the maternal age group of 26-30 years and drops steadily after. Gastrointestinal tract anomalies were most common (no. =28, 25.9%). Residences close to dump sites, telecom masts/base stations, electricity cables, industries and heavy motorised highways contributed to risk factors in 9-12 % of cases.Conclusion: More of younger mothers were affected with gastro intestinal malformations predominating. The location of home environment is a potential risk factor that will require further characterisation.Key words: Congenital disorder, Malformations, Birth defects, Risk factors, Epidemiology, Nigeria, Anambra
OPTIMAL EVAPORATING AND CONDENSING TEMPERATURES OF ORGANIC RANKINE CYCLE IN A HOT AND HUMID ENVIRONMENT
Authors: Ihuoma UV , Diemuodeke EO
Published: June 2021

This paper presents a thermodynamic analysis of an organic Rankine cycle (ORC) in a hot and humid environment. A theoretical procedure is proposed for the determination of the optimal evaporation temperature (OET) and optimal condensing temperature (OCT) of a subcritical ORC plant, which is based on thermodynamic theory; the heat input is selected as the objective function. The OETs and OCTs of 21 working ﬂuids, which comprise wet, isentropic and dry ﬂuids, are determined under given environmental conditions– hot and humid environment. The Engineering Equation Solver (EES) integrated development environment is used to optimize the heat input of the ORC plant. Results suggest that the wet fluids (namely R717, Methanol and Ethanol) have the potential of producing better thermodynamic figure of merit over the other fluid types.   http://dx.doi.org/10.4314/njt.v36i1.14

Published: June 2021

There is availability and large deposits of bentonite (700 million tons in North Eastern part) in Nigeria but the clays had not been abundantly harnessed and enhanced with polymer for drilling fluid formulation because they are mostly composed of calcium montmorillonite. This work was aimed at enhancing Gambe clay using un-fermentable polymers (three carboxy methyl cellulose (CMC) with different average molecular weight). The clay was obtained from Gambe town in Adamawa State, Nigeria, beneficiated for quartz removal, as well as enhancement with Na2CO3 (6 wt.%). The mineral and oxides composition of the clay was determined using X-ray diffraction and X-ray fluorescence analyses respectively, and finally used to formulate the drilling fluid. The effect of the polymer on the rheological and physico-chemical properties of the formulated drilling fluid was investigated employing FANN 35SA viscometer.  It was found that the carboxy methyl cellulose enhanced the plastic viscosity from 1.5 cP to 34 cP and the apparent viscosity from 2.25 cP to 44 cP. The higher the average molecular weight of the sodium carboxy methyl cellulose the higher the apparent and plastic viscosities of the formulated fluid. Similarly, the resultant viscosities compared well with that of commercial standard of 15 cP and 14 cP of apparent and plastic viscosities respectively. The sets of data generated from this work is going to be very useful for water and oil/gas drilling operations. http://dx.doi.org/10.4314/njt.v36i1.15
WATER DEMAND PREDICTION USING ARTIFICIAL NEURAL NETWORK FOR SUPERVISORY CONTROL
Authors: Gwaivangmin BI , Jiya JD
Published: June 2021

With increase in population growth, industrial development and economic activities over the years, water demand could not be met in a water distribution network.  Thus, water demand forecasting becomes necessary at the demand nodes.  This paper presents Hourly water demand prediction at the demand nodes of a water distribution network using NeuNet Pro 2.3 neural network software and the monitoring and control of water distribution using supervisory control.  The case study is the Laminga Water Treatment Plant and its water distribution network, Jos.  The proposed model will be developed based on historic records of water demand in the 15 selected demand nodes for 60 days, 24 hours run. The data set is categorized into two set, one for training the neural network and the other for testing, with a learning rate of 50 and hidden nodes of 10 of the neural network model.  The prediction results revealed a satisfactory performance of the neural network prediction of the water demand. The predictions are then used for supervisory control to remotely control and monitor the hydraulic parameters of the water demand nodes. The practical application in the plant will cut down the cost of water production and even to a large extend provide optimal operation of the distribution networks solving the perennial problem of water scarcity in Jos. http://dx.doi.org/10.4314/njt.v36i1.19
