A highly porous metal-organic framework (DUT-8(Ni), DUT = Dresden University of Technology) is found to adopt a configurationally-degenerate family of disordered states that respond adaptively to specific guest stimuli. This disorder originates from non-linear carboxylate linkers arranging paddlewheels in closed loops of different local symmetries that in turn propagate as tilings of characteristic complex superstructures. Solvent exchange stimulates the formation of distinct disordered superstructures for specific guest molecules. Electron diffraction by desolvated DUT-8(Ni) nanoparticles demonstrates these superstructures to persist on the nanodomain level. Remarkably, guest exchange stimulates reversible and repeatable switching transitions between distinct disorder states. Deuterium NMR spectroscopy and in situ PXRD studies identify the transformation mechanism as an adaptive singular transformation event.

Authors: Sundar Mahati , R Archana
Published: May 2020

A health professional requires resilience to be able to handle the depression, anxiety and stress, which may occur when they are in the field. Resilience is theability to tackle and overcome difficulties, with personal transformation and growth. Studies in undergraduate medical students have shown a difference in the stress scores of males and females, showing the possibility of gender difference in coping strategies and resilience. Therefore, the objective of the study was to assess the resilience scores of undergraduate medical students and to find out the existence of gender differences in their resilience scores. A cross-sectional study was conducted among the first and second-year MBBS students of 18-25 years of age after obtaining informed consent and Institutional ethical clearance. All willing male and female students fulfilling the inclusion and exclusion criteria formed the study participants. A standard resilience questionnaire was used to assess the resilience scores of the students and the male and female participants scores were noted separately. A total of of282 first and second-year undergraduate medical students participated in the study. A significantly higher percentage of female students had a high resilience score in comparison to male participants. Our study highlights the fact that females have a higher resilience compared to males. But still, the majority of male and female students are having moderate resilience. Thus, the future focus should be on the promotion of resilience-building measures to be taught to the students early in their medical curriculum to successfully tackle the stressful situations.

Published: May 2020

In the world, under-nutrition accounts for a large scale of infant and child mortality, one of the causes being suboptimal breastfeeding and complementary feeding. It is important that adequate nutrition have to be provided during the period of first and second year of life to prevent impaired developmental milestones and the overall health of the child since it is very common in India. The main aim of this study is to assess the knowledge and feeding practices among mothers of infants and children aged between 6 and 23 months. A cross-sectional study was conducted using a pre-tested structured questionnaire, which was developed based on (Infant and Young Children Feeding practices) IYCF, on 101 mothers of infants and children aged between 6 and 23 months in Thirumazhisai, Chennai. Among the 101 mothers interviewed, 93% of them had knowledge of early initiation of breastfeeding, but only 87.1% of the children were given breastfeeding within 1 hour of birth and exclusive breastfeeding practices were followed in 94% of the mothers. Statistical significant association was found between Exclusive breastfeeding and age< 25 years, socio-economic status and education. The prevalence of pre-lacteal feeding was 13.9%. Though there is adequate knowledge and feeding practices followed, further research is needed to quantify the gaps among the knowledge and practice of feeding practices among the study population.

Published: May 2020

Healthcare is a demanding profession and often, while performing their roles, healthcare workers face multiple occupational and personal stresses that may influence their ability to maintain positive dietary habits. Nutritional adequacy is the comparison between the nutrient requirement and the intake of a certain individual or population. Due to the limited availability of data on the dietary diversity of healthcare workers in India, an attempt was made to conduct an across-sectional study of the dietary diversity of healthcare workers working in a tertiary hospital. The sampling frame comprised of various hospital staff and healthcare workers who were working in the hospital and a total of 119 were examined. The study tool was prepared based on the FAO dietary diversity questionnaire Details about age, gender, and details regarding their jobs, such as shift work, were collected. A score of >11 was considered as the operational definition for a diverse diet. The socio-demographic variables of study participants, when analyzed show than early 90% (107) of the study population, were aged below thirty (30) years. Amongst the 119 subjects, 19 (16%) were male and 100 (84%) were female. Almost two thirds (58.8%) of the population involved worked in shifts. A majority of the subjects 18 (26.8%) opted for taste as the major determinant, followed by Stress at 15 (22.3%) and Cost with 12 (17.9%) subjects. When compared, dietary diversity in males was found to be much better. In conclusion, there is a significant absence of dietary diversity and the presence of nutrient inadequacy among the hospital staff and health care workers. This inadequacy is present primarily due to the ignorance and lifestyle choices of the subjects involved.

Published: May 2020

Rabies is a major health issue in the urban areas where there are many free roaming dogs. The absence of knowledge among people regarding the management of dog bites results in increased death due to rabies. Myths and indigenous methods have a greater influence on people than the available vaccines with proven efficacy. Rabies is a 100% fatal disease that can be prevented by timely intervention. Knowledge, attitude and practice among the people play an important role in reducing death due to rabies.So this study aims to assess and evaluate the knowledge, attitude and behaviour on dog bites and its management in the prevention of rabies among general population. A Pretested questionnaire regarding the knowledge, attitude and behaviour on dog bites and it management, containing 34 questions, was used. A cross sectional descriptive study was performed on 205 residents of an urban area (Thirumazhisai) in Tamil Nadu. The data obtained was analysed using SPSS10. A total of 205 subjects were studied. 52 subjects had heard of rabies and knew that it could be spread by animal bite. Regarding the animals that could spread rabies, 52 subjects reported dogs to be the most common source, the second commonest response being cats (24 subjects). Knowledge, attitude and behaviour study suggests that there is need to create awareness amongst the masses regarding epidemiology of the disease and merits of prompt and appropriate post exposure treatment.

Published: May 2020

Children of present day are exposed to excessive screen time from a very young age itself. Among the factors which contribute to this is easy accessibility to gadgets, nuclear families with less support for childrearing due to parental preoccupation, etc. Though there are studies addressing the association between screen time and health effects, there isn’t’ any study addressing the effect of screen time on progress of therapy session in children with special needs, especially Autism or social communication disorders. For the present study, we enrolled children between 2-5years with ASD / SCD and assessed their initial problems and improvement post interventions with ATEC scoring. They were questioned about the screen time their children were exposed initially as well as at the end of training duration and were grouped as <1 hour and >1 hour. Following complete assessment using all the required tools, the children were given all the required standardised therapies according to our unit protocol for ASD and SCD, respectively. This includes sessions of Occupational therapy, speech therapy, ABA, etc. for 6 months. The effect of the sessions in the form of improvement in ATEC scores- total and individual domain scores of both ASD and SCD children were correlated with the screen time exposure and assessed for significance. 70 % of the kids with special needs (ASD& SCD) had media exposure >1 hours in the first year itself and were continuing at >2 hour/day. The present study showed that screen time has significant negative influence affecting improvement following therapies in both ASD and SCD. But ASD children seem to be more affected than SCD. ATEC scoring may be used in both ASD and SCD for follow-up assessment. However, this may require a larger sample for further validation. We caution the use of low quality Screen media intervention in therapy sessions or home for engaging these 2 groups of children.

Authors: K V Jinu , R Archana , J K Mukkadan
Published: May 2020

Glutamate is an excitatory neurotransmitter which is essential for cognition but, at the same time, a neurotoxin if accumulated beyond a certain level. The derangement of glutamate level in brain is closely associated with Alzheimer’s disease. Vestibular stimulation is known to stabilize various neuro-chemical transmission in central nervous system, especially effective in enhancing acetyl choline level and reduction of acetyl cholinesterase level. So the current study has undertaken to evaluate glutamate level in dementia and vestibular stimulation groups and its role in improving memory and anxiety scores.  In the present study, 32 Wistar rats were used. Scopolamine was used to induce dementia and caloric stimulation (bilateral, unilateral right and unilateral left) was used stimulate vestibular system. Behavioral parameters like water maze used to asses memory and elevated plus maze was used to assess anxiety in our study. Glutamate was quantified by spectroflurimetry and histopathology of hippocampus and cortex were assessed. Caloric vestibular stimulation effectively reduced glutamate level near to normal values and this result reflected in increased memory scores in water maze and increased exploratory activities in elevated plus maze. Especially unilateral left vestibular stimulation has found beneficial in reducing glutamate level. All these positive outcomes have proven that vestibular stimulation can increase memory and anxiety scores in dementia and thereby can be used as an alternative therapy in this field. Further animal studies and human studies are needed to dig deep into the molecular mechanisms behind its actions.

Published: May 2020

Patient safety is a critical topic in health care globally, with implications for nurses, physicians, administrators, and most importantly, patients and their well-being. Online distance learning (ODL) is widely accepted among most disciplines in higher education and has been used to promote patient safety knowledge among health care students and professionals in diverse contexts. This article reports on an online Nursing and Patient Safety course developed in 2012 by the University of Miami School of Nursing and Health Studies in conjunction with the Pan American Health Organization and the International Network for Nursing and Patient Safety. The study’s objectives are to describe the implementation of an international ODL program to enhance patient safety knowledge in nurses and nursing students, and to examine the participants’ assessments of this online approach as an effective learning tool. Most participants who completed the Nursing and Patient Safety ODL course reported being satisfied with the course content and experience, and demonstrated increased knowledge on patient safety, as measured by post-module quizzes and self-report. Limitations of the study include the lack of a comparison group, disparity in the number of participants across the course’s language formats (English, Portuguese, Spanish), and the large number of participants who registered for but did not complete the course. Future research should identify obstacles to course completion, explore participants’ awareness of patient safety issues and perceived need for more instruction, and look at ways to disseminate the course to the broadest international population of nurses and nursing students.

Published: May 2020

Objective. To inform about the most recent epidemiological trends and integrated programmatic response to tuberculosis (TB) and HIV coinfection in Latin America and the Caribbean (LAC).

Methods. A descriptive review analyzed the most relevant indicators on TB/HIV coinfection in 33 countries in LAC with a cross-sectional and time-trend approach. Data were obtained from publicly available databases and analyzed through simple proportions, weighted means, and risk ratios.

Results. In LAC, during 2017, 80.8% of TB patients were actively screened for HIV, with a 25.6% increase between 2011 and 2017. In the same year, the proportion of TB patients with HIV-positive status was 11.2%, with a small but progressive reduction of 5% since 2011. The provision of antiretroviral therapy and anti-TB medication among TB/HIV coinfected patients for 2017 was at 60%. Only one-third of people living with HIV had access to isoniazid preventive therapy. Overall, the mortality in the TB/HIV cohort has not changed since 2012, hovering at around 20%.

Conclusions. TB/HIV collaborative activities, as the backbone to address TB/HIV coinfection, are being scaled up in LAC and some indicators show a tendency toward improvement; nevertheless, our review shed light on the need to keep strengthening integration of service delivery, joint monitoring and evaluation, and data quality.

COVID-19 will be with us through the remainder of 2020 and almost certainly beyond. New Zealand needs a viable strategy to protect its populace until a vaccine is developed and in wide use. Until that time, it makes sense to protect the population by putting in place treatments that will be safe and effective, such as the use of convalescent sera and the use of direct-acting anti-virals. These treatments should be sourced externally or made locally, but steps in this direction must now begin as the lockdown ends. New Zealand has the scientists, the facilities and the will to make this happen, but the support of the government and the population will be needed if this plan is to succeed.

AbstractCollaborative economy refers to social and economic sharing activities that make entities (customer and peer provider) in-service ecosystem can access services through technology or digital platform. This research aims to give a better understanding of activities and interaction between entities that can potentially elevate the existence of peer-to-peer (P2P) accommodation in Indonesia. Although research regarding the collaborative economy has been accelerating, there has not been a formal conceptualization of interaction from a broadening perspective as a service ecosystem in the context of co-creation. Preliminary study becomes crucial and relevant with the raising of the collaborative economy, based on the consideration that no previous research is considered to be able to explain the dynamics of interaction by using a perspective of Service-Dominant Logic (S-D Logic). This study seeks to answer two research questions, what interactions occur outside consumers, peer providers, platform providers, and how co-creation might be created in the P2P service ecosystem. This conceptual paper draws on the interaction from the perspective of co-creation between entities and stakeholders as a lens by using the systematic-qualitative approach. In general, this study uses the Soft System Methodology (SSM) precisely defining an unstructured situation in the real world. This study tries to initiate the development of phases of co-creation between entities in the service ecosystem. The outcomes of this study enrich the body of knowledge of service science, especially on the way to apply the framework value co-creation. The development of a better service ecosystem across particular engagement remains critical.

Authors: AKSU Gizem , ALTAY Hamit
Published: May 2020

This is the first in a series of papers describing the effects of potassium applications on drought stress in sugar beet. Drought stress is the stress to which there is the most exposure in agricultural areas. In this research, the effect of potassium applications under drought stress on some quality parameters of sugar beet, which is a strategic plant, was investigated. In the experiment, irrigation levels were kept at 33%, 66% and 100% of field capacity. Different doses (10-20-40-80 mg kg-1) of potassium were applied to the plants. The plants were grown in the growth chamber under controlled conditions (day/night 16/8 hours, 25/15 0C, 60-70% humidity). A comparison of the plants irrigated at the level of 100% of the field capacity and stressed plants showed that the root sugar content decreased by 53.18% and 65.1%, and shoot sugar content by 20.8% and 17.8% respectively at 66% and 33% irrigation levels. Root white sugar content (58.61 mg g-1) was obtained at the dose of 10 mg kg-1 potassium level, while the lowest (32.61 mg g-1) was obtained at the dose of 80 mg kg-1 potassium level. Shoot protein content has increased significantly with an increasing level of potassium under drought (33% and 66%) condition. The root α-amino nitrogen content decreased under drought stress with increasing potassium concentrations while it increased in non-stressed plants. According to the results obtained from the experiment, the potassium applied to the plants under drought stress led to the increase of the root sugar, root white sugar content and shoot protein content the reduction of root α-amino nitrogen content. Therefore, it can be said that potassium may play a critical role in reducing the negative effect of drought stress in sugar beet.
FRICTION ANALYSIS IN CASE OF THE CARRIAGE- FEED SHAFT CINEMATIC COUPLING AT CNC LATHE
Authors: Popescu Daniel
Published: May 2020

The paper presents a mathematical model for analysis of friction between the tool bearing saddle and conductor at CNC lathe. The analysis of longitudinal advance movement laws is performed taking into account the appearance and development of disturbing harmonic forces created by auto-vibrations determined by the interaction between the partial elastic systems of tool and workpiece. The friction force is emphasized as product of two components depending on the sliding speed and on the normal disturbing force. By establishing the dynamic response of the system, when the normal force depends linearly on speed, acceleration and mobile ensemble position, the premises are created for stability analysis of the friction movement, obtaining the limit speeds under which the stick-slip phenomenon occurs. Thus, it is provided for a rational design of CNC lathe elastic structure, in order to improve the surface quality and the dimensional precision.

Published: May 2020

Endometriosis is characterized by the presence of ectopic endometrial-like tissue in extra-uterine sites which may induce chronic inflammatory reaction, scar tissue, and adhesions that may distort the pelvic anatomy. The true prevalence of the disease is not known. The disease usually affects women of the reproductive age group and is most typically diagnosed in women aged between 25-30years. Some of the factors which increase the risk of disease include early menarche, shorter menstrual cycles and nulliparity. The symptoms are often non-specific making diagnosis difficult with resultant delay in initiation of appropriate therapy. However, chronic cyclical or non-cyclical pelvic pain with or without menstrual abnormality is common. This review describes the various management options in endometriosis with emphasis on the effective medical and surgical interventions which are useful in the developing world.

Background: Juvenile Idiopathic Arthritis (JIA) is one of the common chronic diseases in childhood. The inflammatory process in the joint is triggered by pro-inflammatory cytokines. The treatment is directed at alleviation of pain, inhibition of disease activity and preservation of range of motion. Objectives: To describe the spectrum of clinical presentations, laboratory parameters and drug therapy among patients with Juvenile Idiopathic Arthritis seen at a Tertiary Health Centre. Methods: All the patients who fulfilled the classification criteria of the International League of Associations for Rheumatology for JIA between July 2012 and June 2016 were included in the study. The clinical features, results of laboratory investigations and the treatment received were recorded. Results: A total of 1910 patients were seen at the Out-Patient Rheumatology Clinic over the 4-year period but only 18 case files of patients with JIA (0.95% of total) were retrieved. There were 13 females and 5 males with a female-to-male ratio of 2.6:1. The age range was 8-15 years with a mean of 10.3 ± 2.1 years. The duration of symptoms prior to presentation ranged between 2 years and 7 years with a mean of 4.2 ± 1.3 years. Polyarticular presentation was observed among 61.1% (11/18), pauciarticular in 27.8% (5/18) and systemic in 11.1% (2/18). Fever was uniformly seen among the patients with systemic onset, while fever and joint swelling were the common presentations in the other groups. Knee and ankle joints were most commonly affected. Erythrocyte Sedimentation Rate was elevated in 88.9% of the patients. Methotrexate was used in 61.1% and combination therapy was used as necessary. Conclusion: JIA is relatively uncommon in the setting of study. Polyarthritis form of JIA was the commonest type and response to steroid was uniformly good. Early recognition of the subtypes of JIA will enhance effective management of cases.
Malaria and the Sickle Gene: Polymorphism Balance in favour of eradication
Authors: Olatunji Phillip O
Published: May 2020

Evolutionally, the single nucleotide mutation responsible for the sickle haemoglobin gene, (HbS gene) developed from the regions of the world where malaria is holoendemic, leading to the explanation that the mutation is in response to the presence of the malaria parasite. Studies eventually showed that individuals that are heterozygous for the HbS gene are protected from the lethal clinical effects of malaria infection. In other words, malaria confers a survival advantage to carriers of the HbS gene, and this is referred to as balanced polymorphism. On the other hand, malaria infection is associated with significant morbidity and mortality, particularly among children. Unfortunately, lack of success in the effort to eradicate the malaria parasite through the elimination of the Anopheles mosquito or efforts to limit its contact with human being has produced little success, hence the resort to roll back malaria, with the aim of reducing the morbidity and mortality associated with it.   Therefore, it is attractive to consider what will happen to the sickle gene if malaria were to be eradicated. That is, the possibility is that the sickle gene may also follow suit since its evolution in the first instance was as a response to malaria., This is the hypothesis being propounded by this article. In that case, rather than shy away from the malaria eradication initiative, it should remain the goal of all malaria programs.
Visual loss from mismanaged ocular injury with foreign body impaction: A Case Report
Authors: Akintoye Ifedayo O. , Adeoti Caroline O.
Published: May 2020

Ocular injury occurs commonly and it may lead to visual impairment if it is not properly managed. We report the case of a 35-year old man with a retained infected ocular foreign body in his right eye following an injury. The foreign body was not discovered despite consulting non-ophthalmologists at a Maternity Centre and an Optical Shop over a period of ten days.  At presentation at the Specialist Hospital, he was unable to see with swelling of the eyelid, red eye and discharge. On examination, the visual acuity in the affected eye was NLP and an infected stick that penetrated the eyeball was discovered in the superonasal aspect of sclera covered by the swollen upper lid. This resulted in endophthalmitis, cataract and blindness of that eye. Ocular injuries must be promptly referred to the ophthalmologist for appropriate care and to prevent complications. The case clearly showed a diagnostic and therapeutic challenge for paramedics who encounter eye injuries outside the tertiary hospital setting. Therefore, this report raises public health concern intended to increase awareness on the management of eye injuries. The incorporation of Primary Eye Health into Primary Health Care along with training and re-training of Community Health Extension Workers, General Practitioners and other rural health workers cannot be overemphasized.

Published: May 2020

Background:  Auto mechanics are exposed to various organic, inorganic and particulate matters as a result of their occupation. Determining the association between environmental pollutant and risk of lung function abnormalities among auto mechanics is important to prevent long-termCem>Objective: To describe lung function abnormalities and their determinants among auto mechanics in Ogbomoso, Nigeria. Methods: One hundred and three auto mechanics were randomly selected from Ogbomoso, Nigeria. Their clinical and demographic data were obtained using a data form. Spirometry was performed using the CONTEC handheld Spirometer. The personal best values of three measurements FEV1, FVC and PEFR were determined. Lung function abnormalities were described according to standardized criteria. Results: The mean (SD) age of the participants was 38.5 (11.9) years. The mean systolic blood pressure, mean diastolic pressure and mean duration of the job as auto mechanics were 128.7 (17.9) mmHg, 81.2 (11.4) mmHg and 20.2 (12.5) years respectively. Restrictive, obstructive and mixed lung function abnormalities were demonstrated among 53%, 10% and 2% respectively. The mean values of FEV1 and FVC reduced significantly with increasing job duration. Conclusion: Lung function abnormalities occurred frequently among auto mechanics in Ogbomoso, Nigeria. There seemed to be a progressive decline in lung functions with age and duration of exposure to organic and inorganic pollutants by auto mechanics. Strict environmental and occupational safety measures may limit the hazards associated with poor air quality and other chemical/physical hazards among auto mechanics in Nigeria.

Published: May 2020

Background: The World Health Organization prescribed that Youth-Friendly health services must be accessible, acceptable, equitable, efficient, effective, comprehensive and appropriate to meet the health needs of young people. Objective: To compare the clients’ and service providers’ assessment of services offered at the public and Non-Governmental Organization (NGO) Youth Friendly facilities (YFF) in Lagos Nigeria. Methods: A mixed method approach was used. Structured questionnaires were administered on youths (294 from public and 273 from NGO YFF) from ten (5 public and 5 NGO) YFF. Ten key informant interviews with service providers were also conducted between March 1st and December 31st 2014. SPSS version 22 was used to analyze quantitative data while thematic analysis of interviews with service providers was done. Results: Youths who utilized the public YFF had 60% chance (AOR 1.6, 95%CI 1.3 – 2.5, p= 0.005) of experiencing longer waiting times, 80% chance (AOR 1.8, 95%CI 1.2 – 2.8, p=0.004) of being counseled in a separate room and over two-fold chance (AOR 2.3, 95%CI 1.7 – 3.3, p <0.001) of having free services. Sexual and reproductive health was the major complaint area of the youths while funding was the major challenge of service providers at both the public and NGO YFF. Conclusion: To address the needs of the youths, there is a need to provide more funds and provide necessary logistics required by YFF.

Authors: Atimati Anthony Oyovwikigho , Ikhurionan Paul
Published: May 2020

Progressive Familial Intra-hepatic Cholestasis (PFIC) is a group of heterogeneous, autosomal recessive disorders characterized by cholestasis, jaundice and mutilating pruritus, mostly in infancy. The incidence of PFIC ranges from 1:50,000 to 1:100,000. There are three subtypes; Types 1 and 2 typically present in the neonatal period and early infancy while Type 3 can present in early infancy, childhood or adolescence. This report is about a 6-year old Nigerian girl who presented with jaundice and severe pruritus of one-month duration and abdominal pain of a week duration. The symptoms were preceded by ingestion of Atropine meant for ocular examination two days earlier. She was well-nourished, deeply icteric, had generalized healing scratch marks and hepatomegaly. The laboratory findings included conjugated hyperbilirubinaemia, moderately elevated liver transaminases and Gamma-Glutamyltransferase enzymes. She was managed for PFIC3 using oral ursodeoxycholic acid with complete resolution of the disease.

Background: Adolescents constitute a significant proportion of the vulnerable group in the society and often engage in risky sexual behaviours which predispose to HIV/AIDS. Objective: To assess the knowledge, attitude, preventive practices of HIV/AIDS and its associated factors among adolescents in Ora community, Edo State. Methods: A descriptive cross-sectional study was carried out among 440 secondary school students selected by stratified sampling technique. Data was obtained with pretested interviewer-administered questionnaires. Results: Two hundred and forty-two (242; 55.0%) of the respondents were aged 10 – 14 years. Two hundred and seventy-one 271 (61.6%) of the respondents had good knowledge of HIV/AIDS, while 291 (59.3%) had a positive attitude towards HIV/AIDS. Age 15 – 19 years (p = 0.001) male sex (p = 0.049) and respondents in SS2 class (p = 0.005) were significantly associated with knowledge. A negative attitude was recorded among 139 (51.3%) students who had good knowledge. The relationship between knowledge and attitude towards HIV/AIDS was statistically significant (p = 0.01). Twenty-five (73.5%) of the sexually active respondents had poor preventive practice regarding HIV/AIDS. Conclusion: More than half of the students had good knowledge and positive attitude towards HIV/AIDS while a majority of them who were sexually active had poor preventive practices. Respondents aged 15 – 19 years, males and in SS2 class significantly had good knowledge of HIV/AIDS. Health education intervention programs targeted on the prevention of HIV/AIDS should be designed for Secondary School Students.

Published: May 2020

Background: In academia, the aphorism 'publish or perish' is commonly used. The pressure to publish academic papers can sometimes lead researchers to engage in unethical practices in the conduct, reporting or publishing of their research works.

Objective: To assess the awareness and practices of ethical issues in the conduct, reporting, and publishing of research among academics.

Methods: The study was a descriptive, cross-sectional survey of the academic staff of a Nigerian medical college. A structured questionnaire was used to collect relevant information about publishing experience and observation of practices considered to be acts of research misconduct.

Results: A total of 94 out of 108 academics responded to the questionnaires giving a response rate of 87%. The commonest act of research misconduct reported by the respondents was plagiarism with an incidence rate of 25%. The incidence rates for awareness of data fabrication and falsification were 22% and 21% respectively. The proportions of respondents who were aware of gift and ghost authorship were 63% and 20% respectively. Only 41% of the respondents could recall all the criteria for authorship of an academic paper while 20% could not recollect any of the criteria.

Conclusion: Research misconduct and unethical publication practices are common observations among the respondents in this survey. It is recommended that researchers should familiarize themselves with the various ethical guidelines and requirements for authorship and agree on the sequence of the names of authors in the by-line of the proposed publication at the start of project work.
