The delivery of high quality health care is crucial to achieving enhanced health benefits, patient safety and a positive patient experience of health care. This article provides insight on the quality of the health care delivery in Nigeria and aim to uncover if quality health care in Nigeria is a reality or a myth. Relevant information was abstracted from included articles and used to provide both descriptive and analytical discourse on the subject. Discussions and reflections were carried out along an established quality framework of treatment effectiveness, acceptability, efficiency, the appropriateness of the means of delivery as well as equity. The slow pace of development of quality systems in health service delivery in Nigeria is evidenced by the poor quality of health services as well as the poor health status of the population. The pace of developing quality systems in health care delivery in Nigeria is unsatisfactory. There is a need to galvanise the efforts of relevant stakeholders including the patient in charting a new agenda for health care quality improvement in Nigeria.

Background:Studies carried out in the Niger Delta region of Nigeria have demonstrated a link between oil exploration and poor-quality drinking water. However, many of these studies have been limited by small coverage and focus on few parameters. This study thus aimed at a comprehensive assessment of the quality of public sources of drinking water in three gas flaring and three non-gas flaring communities in the Niger Delta region of Nigeria.Methods:A total of 13 samples were collected from the major sources of drinking water in six communities in Rivers, Bayelsa and Delta States, Nigeria. These were stored and transported in line with International standards to a certified environmental laboratory where physical, chemical, bacteriological and petro-chemical assessments were conducted for 27 parameters.Results:Some samples had a pH below the normal range for drinking water, with median pH value of 4.63. All chemical parameters assessed fell below the normal acceptable range with exception of magnesium which exceeded the acceptable range. There were11 samples (91.7%) with microbial contamination; total and faecal coliform demonstrated at values ranging between 15 and 90 most probably number (MPN)/100 ml for total coliform and 9 to 23 MPN/100 ml for faecal coliforms. Oil, grease and total petroleum hydrocarbons (TPH) were identified in water samples from all communities. Values for oil and grease ranged between <0.001 and 0.015 mg/l, while TPH values were between <0.001 and 0.046 mg/l. There was no significant difference between median values in gas flaring and non-gas flaring communities.Conclusion:Distortion of physico-chemical properties, and hydrocarbon and faecal contamination of drinking water are a major challenge in oil-bearing communities in the Niger Delta region of Nigeria irrespective of gas flaring status. This calls for urgent interventions to improve the quality of drinking water for the people of the Niger Delta.

Human diet comprises several classes of phytochemicals some of which are potentially active against human pathogenic viruses. This study examined available evidence that identifies existing food plants or constituents of edible foods that have been reported to inhibit viral pathogenesis of the human respiratory tract. SCOPUS and PUBMED databases were searched with keywords designed to retrieve articles that investigated the effect of plant-derived food grade substances (PDFGS) on the activities of human pathogenic viruses. Eligible studies for this review were those done on viruses that infect the human respiratory tract. Forty six (46) studies met the specified inclusion criteria from the initial 5,734 hits. The selected studies investigated the effects of different PDFGS on the infectivity, proliferation and cytotoxicity of different respiratory viruses including influenza A virus (IAV), influenza B virus (IBV), Respiratory syncytial virus (RSV), human parainfluenza virus (hPIV), Human coronavirus NL63 (HCoV-NL63), and rhinovirus (RV) in cell lines and mouse models. This review reveals that PDFGS inhibits different stages of the pathological pathways of respiratory viruses including cell entry, replication, viral release and viral-induced dysregulation of cellular homeostasis and functions. These alterations eventually lead to the reduction of virus titer, viral-induced cellular damages and improved survival of host cells. Major food constituents active against respiratory viruses include flavonoids, phenolic acids, tannins, lectins, vitamin D, curcumin, and plant glycosides such as glycyrrhizin, acteoside, geniposide, and iridoid glycosides. Herbal teas such as guava tea, green and black tea, adlay tea, cistanche tea, kuding tea, licorice extracts, and edible bird nest extracts were also effective against respiratory viruses in vitro. The authors of this review recommend an increased consumption of foods rich in these PDFGS including legumes, fruits (e.g berries, citrus), tea, fatty fish and curcumin amongst human populations with high prevalence of respiratory viral infections in order to prevent, manage and/or reduce the severity of respiratory virus infections.

Background: Musculoskeletal disorders affecting medical personnel should never be treated lightly. It has thus become necessary to strictly infuse ergonomics in medical practice in order to tackle the occurrence of musculoskeletal system disorders. This would ensure better productivity among the medical personnel. This research was conducted to determine the knowledge, attitude and practice of the prevention of work-related musculoskeletal disorders among doctors working at the University of Port-Harcourt Teaching Hospital.Methods: A descriptive, cross-sectional study design was employed in carrying out this study among doctors working at the University of Port Harcourt Teaching Hospital. Multistage sampling was utilized in selecting a sample population of 223 doctors for this study. Data collection was done using a semi-structured self-administered questionnaire. Ethical approval to conduct this study was gotten from the University of Port-Harcourt research ethics committee. Consent, confidentiality, privacy and beneficence were ensured in this study. For test of associations, statistical significance was set at 0.05.Results: Majority of the respondents had good knowledge and attitude towards musculoskeletal disorders’ prevention at work. The practice of ergonomic principles was however not satisfactory. Occurrence of work-related musculoskeletal disorders among study respondents was significantly associated with the knowledge and practice of ergonomic principles required to prevent the occurrence of these disorders.Conclusion: Despite the significant proportion of doctors in this study having good knowledge and attitude towards prevention of musculoskeletal system disorders at work, only few of these doctors satisfactorily practiced the necessary preventive measures necessary to prevent these disorders. This inadvertently resulted in the high prevalence of these disorders found in this study. It is recommended that a re-orientation of doctors to be more involved in the actual application of ergonomics while working no matter the compulsion or desire to get the work done should be done.
