Percentage Incidences of Bacteria in Mahseer (Tor putitora), Silver carp (Hypophthalmichthys molitrix) Fish Collected from Hatcheries and Local Markets of District Malakand and Peshawar of Khyber Pakhtunkhwa, Pakistan

Abstract Fish is the main source of animal protein for human diet. The aim of this study was to find out prevalence of pathogenic bacteria of two selected economically important fish of Pakistan namely Mahseer (Tor putitora) and Silver carp (Hypophthalmichthys molitrix). Live fish samples from hatcheries and dead fish samples from different markets of study area were randomly collected. The fish samples were analyzed for isolation, identification and prevalence of bacteria. The isolated bacteria from study fish were identified through biochemical test and about 10 species of pathogenic bacteria were identified including the pathogenic bacteria to human and fish namely, Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus iniae, Serratia spp. Citrobacter spp. Stenotrophomonas spp. Bacillus spp. and Salmonella spp. The bacterial percentage frequency of occurrence in Silver carp and Mahseer fish showed Pseudomonas aeruginosa 21.42%, Staphylococcus epidermidis 17.85%, Escherichia coli 11.90%, Staphylococcus aureus 9.52%, Citrobacter spp. 9.52%, Serratia spp. 8.33%, Streptococcus iniae 7.14%, Stenotrophomonas spp. 5.95%, Bacillus spp. 4.76% and Salmonella spp. 3.57%. The study revealed that Fish samples of Mahseer and Silver carp that were collected from markets have found more isolates (10 bacterial species) than did the fresh fish pond samples (03 bacterial species) of hatcheries. The occurrence of pathogenic bacteria in study fish showed risk factor for public health consumers.

Factors associated with the onset of major depressive disorder in adults with type 2 diabetes living in 12 different countries: results from the INTERPRET-DD prospective study.

AIMS: To examine the factors that are associated with changes in depression in people with type 2 diabetes living in 12 different countries. METHODS: People with type 2 diabetes treated in out-patient settings aged 18-65 years underwent a psychiatric assessment to diagnose major depressive disorder (MDD) at baseline and follow-up. At both time points, participants completed the Patient Health Questionnaire (PHQ-9), the WHO five-item Well-being scale (WHO-5) and the Problem Areas in Diabetes (PAID) scale which measures diabetes-related distress. A composite stress score (CSS) (the occurrence of stressful life events and their reported degree of 'upset') between baseline and follow-up was calculated. Demographic data and medical record information were collected. Separate regression analyses were conducted with MDD and PHQ-9 scores as the dependent variables. RESULTS: In total, there were 7.4% (120) incident cases of MDD with 81.5% (1317) continuing to remain free of a diagnosis of MDD. Univariate analyses demonstrated that those with MDD were more likely to be female, less likely to be physically active, more likely to have diabetes complications at baseline and have higher CSS. Mean scores for the WHO-5, PAID and PHQ-9 were poorer in those with incident MDD compared with those who had never had a diagnosis of MDD. Regression analyses demonstrated that higher PHQ-9, lower WHO-5 scores and greater CSS were significant predictors of incident MDD. Significant predictors of PHQ-9 were baseline PHQ-9 score, WHO-5, PAID and CSS. CONCLUSION: This study demonstrates the importance of psychosocial factors in addition to physiological variables in the development of depressive symptoms and incident MDD in people with type 2 diabetes. Stressful life events, depressive symptoms and diabetes-related distress all play a significant role which has implications for practice. A more holistic approach to care, which recognises the interplay of these psychosocial factors, may help to mitigate their impact on diabetes self-management as well as MDD, thus early screening and treatment for symptoms is recommended.

Prevalence and correlates of depressive disorders in people with Type 2 diabetes: results from the International Prevalence and Treatment of Diabetes and Depression (INTERPRET-DD) study, a collaborative study carried out in 14 countries.

AIMS: To assess the prevalence and management of depressive disorders in people with Type 2 diabetes in different countries. METHODS: People with diabetes aged 18-65 years and treated in outpatient settings were recruited in 14 countries and underwent a psychiatric interview. Participants completed the Patient Health Questionnaire and the Problem Areas in Diabetes scale. Demographic and medical record data were collected. RESULTS: A total of 2783 people with Type 2 diabetes (45.3% men, mean duration of diabetes 8.8 years) participated. Overall, 10.6% were diagnosed with current major depressive disorder and 17.0% reported moderate to severe levels of depressive symptomatology (Patient Health Questionnaire scores >9). Multivariable analyses showed that, after controlling for country, current major depressive disorder was significantly associated with gender (women) (P<0.0001), a lower level of education (P<0.05), doing less exercise (P<0.01), higher levels of diabetes distress (P<0.0001) and a previous diagnosis of major depressive disorder (P<0.0001). The proportion of those with either current major depressive disorder or moderate to severe levels of depressive symptomatology who had a diagnosis or any treatment for their depression recorded in their medical records was extremely low and non-existent in many countries (0-29.6%). CONCLUSIONS: Our international study, the largest of this type ever undertaken, shows that people with diabetes frequently have depressive disorders and also significant levels of depressive symptoms. Our findings indicate that the identification and appropriate care for psychological and psychiatric problems is not the norm and suggest a lack of the comprehensive approach to diabetes management that is needed to improve clinical outcomes.

The INTERPRET-DD study of diabetes and depression: a protocol.

AIM: People with diabetes are at an increased risk of developing depression and other psychological disorders. However, little is known about the prevalence, correlates or care pathways in countries other than the UK and the USA. A new study, the International Prevalence and Treatment of Diabetes and Depression Study (INTERPRET-DD) aims to address this dearth of knowledge and identify optimal pathways to care across the globe. METHOD: INTERPRET-DD is a 2-year longitudinal study, taking place in 16 countries' diabetes outpatients' facilities, investigating the recognition and management of depressive disorders in people with Type 2 diabetes. Clinical interviews are used to diagnose depression, with clinical and other data obtained from medical records and through patient interviews. Pathways to care and the impact of treatment for previously unrecognized (undocumented) depression on clinical outcomes and emotional well-being are being investigated. RESULTS: Initial evidence indicates that a range of pathways to care exist, with few of them based on available recommendations for treatment. Pilot data indicates that the instruments we are using to measure both the symptoms and clinical diagnosis of depression are acceptable in our study population and easy to use. CONCLUSIONS: Our study will increase the understanding of the impact of comorbid diabetes and depression and identify the most appropriate (country-specific) pathways via which patients receive their care. It addresses an important public health problem and leads to recommendations for best practice relevant to the different participating centres with regard to the identification and treatment of people with comorbid diabetes and depression.

Effects of maternal depression on breast-feeding.

OBJECTIVE: To see the effects of maternal depression on breast feeding behavior. DESIGN: This is a cross-sectional study. PLACE AND DURATION: The study was carried out at the OPD of the Children's Hospital Pakistan Institute of Medical Sciences Islamabad from October to mid November 2001. SUBJECT/METHODS: One hundred mothers with children of breast feeding age from 2 months to 2 years were interviewed. These women were visiting the OPD of the Children's Hospital Pakistan Institute of Medical Sciences, Islamabad for medical check up of their children. The interview included the administration of the Urdu version of Hospital Anxiety and depression Scale (HADS). RESULTS: Thirty eight percent of the women had stopped breast feeding and their mean score on HADS was 19.66. whereas 62% of the women were breast feeding their children with a mean score of 3.27 on HADS. Out of the non breast feeding mothers 36.8% reported that their depressive symptoms preceded cessation of breast feeding. CONCLUSION: Maternal depression effects the breast feeding behavior of the mother. It causes mothers to stop breast feeding their children.

A review of patients on methadone maintenance.

This study involves a review of 178 patients on a strictly monitored methadone maintenance programme. All patients had a minimum of 9 years of intravenous drug misuse. 35.7% were HIV positive, 55.7% males and 29% females had previous prison sentences. On average patients had undergone 3.26 out-patient and 0.9 in-patient detoxification. 46.1% had attempted rehabilitation in the past. Out of 25,470 urine samples obtained while on the programme, 10.8% were positive for opiates, 19.2% for benzodiazepines, 32.5% for cannabis, 4.92% for alcohol and 2.27% for amphetamines. Long history of misuse, multiple custodial sentences, previous unsuccessful rehabilitation and positive HIV status were associated with acceptance for maintenance. Frequency of urinalysis, and results triggering dose change can effectively reduce illicit drug use.
