ABSTRACT

Persicaria bistorta is a perennial herb used traditionally in treating various ailments, including diarrhea, abdominal pain, and bleeding. In this study, we used gas chromatography-mass spectrometry (GC-MS) analysis to identify the chemical composition of Persicaria bistorta. The GC-MS analysis revealed the presence of several compounds, including flavonoids, tannins, saponins, and alkaloids. Among those, the most important from medicinal points of view are ethyl oleate (3%), cyclotetradecane (4.74%), dodecanoic acid (4.69%), hexadecanoic acid (5.61%), tetradecane (5.25%), cis-13-octadecenoic acid (10.91%), and bis(2-ethylhexyl) phthalate (32%). The GC-MS analysis of ethanolic fraction of Persicaria bistorta involved in antibacterial activity showed about 18 compounds. Among those, the most important from a medicinal and nutritional point of view are bis(2-ethylhexyl) phthalate (42.20%), 6-octadecenoic acid methyl ester, (Z)- (10.37%), ethyl oleate (6.84%), hexadecanoic acid methyl ester (6.67%), and methyl ester and oleic acid (5.27%). Reported biological antibacterial activity has shown that the main compound determined in both extracts was bis(2-ethylhexyl) phthalate, which has higher peak area percentage in ethanolic extract than in ethyl acetate fraction. Some oily compounds important for health because of their cis-conformation were also revealed in the given study like ethyl oleate and oleic acid. Overall, results suggest that Persicaria bistorta may have therapeutic potential and warrant further investigation. Further research is needed to confirm the efficacy and safety of Persicaria bistorta as a natural medicine and determine its active compounds' mechanisms of action.

ABSTRACT

The primary purpose of the current study was to study the possible pernicious effects of phosphine gas on enzyme activity alterations in Trogoderma granarium to determine its harmfulness to human beings after its prolonged exposure and intake. The saline extract of the adult Khapra beetle was biochemically analyzed at different doses, that is, from 10ppm to 30ppm, to accurately evaluate the effects of various phosphine concentrations (LC30 and LC50) on 2 distinct strains of this insect pest gathered from different godowns of Pakistan as resistant (Chitral [Chi], Haroon Abad [Hbd], and Lahore [Lhr]) and susceptible (Faqeer wali [Fqw], Khanewal [Khw], and Rawalpindi [Rwp]) populations. Our experimental results suggest that the enzyme levels (AcP, AkP, ALAT, ASAT, LDH, and ICDH) seemed to be elevated with increasing dosage of phosphine from 10ppm to 30ppm in the resistant populace of the susceptible ones. It also illustrates that phosphine and its residues can inhibit the workability of certain enzymes that are vital for respiration and neuro reactions in hexapods and mammals. It has detrimental effects of phosphine on human health profile to consume stored food products containing such tenacious enemies.

ABSTRACT

Paramphistomosis is the most prevalent disease of domestic ruminants, causing heavy economic loss in many countries across the world. The morphological identification of these parasites is difficult, therefore molecular characterization is used to discriminate Paramphistomum species. The present study was conducted to identify Paramphistomum sp. at Mardan District, Khyber Pakhtunkhwa (KPK), Pakistan. All samples of these rumen flukes were collected from buffalo. The gDNA was isolated from the adult parasites and the ITS1 region was amplified for the sequence analysis. All flukes had 100% similarity and there was no intraspecific variation. The Blast results showed that all flukes were P. cervi as they form a single cluster with P. cervi reported from China. The results of the ITS1 sequences of the present study with reference sequencing from China showed eight specific SNPs. This was the first study in which P. cervi was genetically characterized through the ITS1 region of rDNA at District Mardan, Pakistan. It can also be used as a marker for the genetic identification of Paramphistomum species.

ABSTRACT

Although prisoners are considered a vulnerable population, no data repository currently exists to monitor the COVID-19 incidence in Nigerian prisons. To better understand the impact of COVID-19 within the Nigerian prison system, prisons should develop detailed COVID-19 response protocols, implement enhanced point-of-care testing, and initiate contact tracing with meticulous data collection.

ABSTRACT

Tyrosinemia is a rare metabolic disease showing autosomal recessive inheritance associated with a deficiency of the enzyme fumarylacetoacetate hydrolase. Absence of this enzyme results in the accumulation of succinylacetone in the tissues which predominantly results in liver injury, renal tubular damage, and neurological manifestation resembling porphyrias. The complications that can develop without appropriate treatment include renal tubular dysfunction, growth failure, rickets, neurological crises, hepatomegaly, and possible hepatocellular carcinoma. We describe a case of 18-month-old child who presents with fever and gradually progressive abdominal distension. Laboratory and radiological investigations were done that lead to the diagnosis of this rare entity.

ABSTRACT

AIM: To characterize growth trajectories of children who develop multiple sclerosis compared to typically developing, regional peers and Centers for Disease Control (CDC) normative values. METHOD: This case-control study collected weight, height, and body mass index (BMI) in 40 consecutive pediatric patients with multiple sclerosis (28 females, 12 males), in addition to 120 typically developing peers (84 females, 36 males), identified and matched for year of birth, sex, ethnicity, and socio-economic status. BMI values were converted to z-scores based on CDC reference values and were compared with respect to age between our two cohorts and by years relative to multiple sclerosis onset for cases. RESULTS: Median age for the clinical onset of multiple sclerosis was 15 years. BMI z-scores are significantly higher for patients with multiple sclerosis compared to typically developing, demographically-matched peers and CDC standards. These significant differences in BMI are noted from 4 years of age and onward. Height trajectories were similar among case and control individuals and CDC normative values. INTERPRETATION: BMI in pediatric multiple sclerosis is markedly higher, beginning in early childhood, years before the clinical-onset of the disease. WHAT THIS PAPER ADDS: Children with multiple sclerosis are significantly more overweight than typically developing peers at the time of diagnosis. Body mass index trajectories are significantly higher years before the clinical manifestation(s) of multiple sclerosis.

ABSTRACT

Malaria and typhoid fever are among the most endemic diseases in the tropical and developing countries. Both diseases share similar transmission factor and often have the similar symptom. Based on this reason, much medical personnel try to cure both malaria and typhoid instantaneously in each case of suspected Salmonella infection and vice versa. The District Dir (Lower) is a favorable location for the protozoan nourishment and secondly mostly reported cases of malaria and typhoid co-infections. The main objective of this study was to find out the prevalence of malaria and typhoid co-infection in the District Dir (Lower), Khyber Pakhtunkhwa (KPK), Pakistan. The blood samples of 1889 patients were examined from September 2012 to April 2013, out of which 311 (16.46%) were positive for malaria and typhoid. Out of these infected, 117 (38%) sample was positive for malaria, 183 (58%) sample were positive for typhoid while co-infected cases were only 11 (4%). The current results indicate that this area is endemic for malaria and typhoid and co-infection. Its infection is prevalent in both the genders at varying degrees.


A malária e a febre tifóide estão entre as doenças mais endêmicas nos países tropicais e em desenvolvimento. Ambas as doenças compartilham fator de transmissão semelhante e muitas vezes têm sintomas semelhantes. Com base nessa razão, muitos profissionais da saúde tentam curar a malária e a febre tifóide ao mesmo tempo em cada caso de suspeita de infecção por Salmonella e vice-versa. O Distrito Dir (inferior) é um local favorável para a nutrição de protozoários e o segundo local com mais casos reportados de malária e co-infecções tifoides. O principal objetivo deste estudo foi descobrir a prevalência da malária e da co-infecção tifóide nos distritos de Dir (Lower), Khyber Pakhtunkhwa (KPK), Paquistão. As amostras de sangue de 1889 pacientes foram examinadas de setembro de 2012 a abril de 2013, das quais 311 (16,46%) foram positivas para malária e febre tifóide. Destes infectados, 117 (38%) amostras foram positivas para a malária, 183 (58%) amostras foram positivas para a febre tifóide, enquanto os casos co-infectados foram apenas 11 (4%). Os resultados atuais indicam que esta área é endêmica para malária e febre tifóide e co-infecção. Sua infecção é prevalente em ambos os sexos em diferentes graus.

ABSTRACT

Human fascioliasis is a freshwater snail borne, zoonotic disease caused by Fasciola liver flukes which are widely spread throughout Pakistan and has recently proved to be endemic in humans of the Punjab province. To verify whether fasciolids are also affecting humans outside this province, studies were conducted in four communities comprising rural and urban areas of Mardan district, Khyber Pakhtunkha province, northern Pakistan. Activities comprised two surveys, a coprological one to look for Fasciola infection and another to get information on potential human infection sources and risk factors by means of a questionnaire. Out of 540 subjects of all ages surveyed, only 4 children (0.74%) were found positive for Fasciola eggs: two 9- and 13-year old boys and two 7- and 16-year old girls. Burden per child ranged 73-146 eggs per gram of faeces (epg), with an average of 106 ±â€¯15.4 epg. Based on the egg size, the infection was diagnosed to be caused by F. hepatica. Serum analyses showed eosinophilia and elevated enzyme values in liver function tests. The Mardan area fits well to all transmission and epidemiological requirements of F. hepatica, namely the presence of infected livestock reservoirs throughout, the appropriate climatic factors (mainly monthly temperature variation along the year), and the existence of adequate freshwater collections. The existence of the specific lymnaeid snail vector species for F. hepatica transmission was reported in the neighbouring Swat valley time ago. Results show that human fascioliasis may be widespread in Pakistan and that both F. hepatica and F. gigantica may be involved.

ABSTRACT

Gait impairment in multiple sclerosis (MS) can result from muscle weakness, physical fatigue, lack of coordination, and other symptoms. Walking speed, as measured by a number of clinician-administered walking tests, is the primary measure of gait impairment used by clinical researchers, but inertial gait features from body-worn sensors have been proven to add clinical value. This paper seeks to understand and differentiate the physiological significance of four such features with proven value in MS to facilitate adoption by clinical researchers and incorporation in gait monitoring and analysis systems. In addition, this information can be used to select features that might be appropriate in other forms of disability. Two of the four features are computed using the dynamic time warping (DTW) algorithm: The "DTW Score" is based on the usual DTW distance, and the "Warp Score" is based on the warping length. The third feature, based on kernel density estimation (KDE), is the "KDE Peak" value. Finally, the "Causality Index" is based on the phase slope index between inertial signals from different body parts. Relationships between these measures and the aforementioned gait-related symptoms are determined by applying factor analysis to three common, clinical walking outcomes, then correlating the inertial measures as well as walking speed to each extracted factor. Statistically significant differences in correlation coefficients to the three extracted clinical factors support their distinct physiological meaning and suggest they may have complimentary roles in the analysis of MS-related walking disability.

ABSTRACT

A coprological study was performed to assess human fascioliasis in 7200 subjects inhabiting rural communities of localities close to the capital city of Lahore in the northeastern part of the very highly populated Punjab province, Pakistan, a country where human infection had never been reported before 2005. The analysis of 1200 subjects including 50 subjects/month throughout a two-year study in each of six localities surveyed provided an overall prevalence of 1.18%, with a range between 0.67% and 1.75% according to localities. Infection rates did not differ according to gender, excepting a higher rate in females (1.13% vs 0.77%) in one locality. Prevalences according to age groups proved to be higher in 11-20 years with 1.57%, followed by 1.18% in 0-10 years and 0.47% in 21-30 years, while no infection above 30 years. Seasonal prevalences proved to be significantly different when comparing summer and autumn with winter and spring. Monthly prevalences showed two peaks, the highest in August (4.67%) and another in January (2.17%). Correlation studies of monthly prevalences with temperature, humidity, rainfall, and pan evaporation showed significant results only with humidity. Despite prevalences being low, the very high number of inhabitants and population densities of the areas surveyed suggest a wide public health problem potentially infecting up to 150,000 rural people, children included, only in the respective districts. Additionally, the situation becomes of more concern when considering the present climate change trend affecting the Punjab, which indicates a progressively increasing fascioliasis transmission risk in that animal endemic area in the near future.

ABSTRACT

Most multiple sclerosis (MS) patients eventually suffer from mobility impairment, and thus it is critical that walking disability in MS be accurately assessed. The six-minute walk test (6MWT), a reliable MS measure, is traditionally used to determine the distance covered in six minutes using a standard protocol. With the availability of body sensor networks (BSNs), researchers are interested in leveraging BSN data for finding new gait assessment anchors for improved separability performance. Further, current methods for gait assessments are insufficient since assessments are absolute, performed by comparing outcomes to the statistical norms established from diverse patient data despite natural inter-patient variability. For example, walking at a slower pace may be a personal trait rather than a fatigue-induced impact in MS. Thus instead of using actual values, changes in gait features during a 6MWT can be used to draw clinical conclusions and remove inter-subject variability. We use 6MWT gait time series BSN data of MS subjects to determine changes in their gait speed and gait cycle length variance over six minutes. We also determine the relationships between these variables and three subjective assessments, namely functional systems scores, modified fatigue impact scale, and multiple sclerosis walking scale. These relationships are important in order to validate features and make them clinically meaningful for a doctor. In MS, feelings of fatigue can occur more often, and have a greater impact on a subject's daily life. The results show that MS patients who reported high motor-related fatigue slowed down and had high gait cycle length variance in the last minute of the test, in contrast to those on whom fatigue had minimal impact, enhancing the separability between MS subjects of varied disabilities based on their scores. It is also observed that FSS components related to coordination, balance, and physical activities show strong correlation with gait parameters.

ABSTRACT

BACKGROUND: Exclusive Breastfeeding (EBF) refers to the practice of feeding breast milk only, (including expressed breast milk) to infants; and excluding water, other liquids, breast milk substitutes, and solid foods. Inadequately breastfed infants are likely to be undernourished and have childhood infections. EBF knowledge and infant feeding practices have not been studied sufficiently in Sokoto State, Nigeria. We describe the results of a randomized community trial to promote Exclusive Breastfeeding (EBF) in two local government areas Kware and Bodinga selected as intervention and control groups respectively. METHODS: During advocacy meetings with community leaders, a Committee was formed. Members of the Committee were consulted for informed consent and selection of ten female volunteers who would educate mothers about breastfeeding during home visits. Participants comprised mothers of infants who were breastfeeding at the time of the study. A total of 179 mothers were recruited through systematic random sampling from each community. Volunteers conducted in-person interviews using a structured questionnaire and counseled mothers in the intervention group only. RESULTS: At baseline, intervention and control groups differed significantly regarding maternal occupation (P=0.07), and age of the index child (P=0.07). 42% of infants in the intervention group were up to 6 months old and about 30% of them were exclusively breastfed. Intention to EBF was significantly associated with maternal age (P=0.01), education (P=0.00) and women who were exclusively breastfeeding (P=0.00). After counseling, all infants up to 6 months of age were exclusively breastfed. The proportion of mothers with intention to EBF increased significantly with maternal age (P=0.00), occupation (P=0.00) and women who were exclusively breastfeeding (P=0.01). Post-intervention surveys showed that source of information and late initiation of breastfeeding was not significantly associated with intention to EBF. Mothers who reported practicing EBF for 6 months, were older (P=0.00) multi-parous (P=0.05) and more educated (P=0.00) compared to those who did not practice EBF. Among them, significantly increased proportion of women agreed that EBF should be continued during the night (P=0.03), infant should be fed on demand (P=0.05), sick child could be given medication (P=0.02), EBF offered protection against childhood diarrhea (P=0.01), and helped mothers with birth spacing (P=0.00). CONCLUSION: This study shows that there is a need for reaching women with reliable information about infant nutrition in Sokoto State. The results show decreased EBF practice among working mothers, young women, mothers with poor education and fewer than five children. Counseling is a useful strategy for promoting the duration of EBF for six months and for developing support systems for nursing mothers. Working mothers may need additional resources in this setting to enable them to practice EBF.

ABSTRACT

BACKGROUND: To determine whether training of providers participating in franchise clinic networks is associated with increased Family Planning service use among low-income urban families in Pakistan. METHODS: The study uses 2001 survey data consisting of interviews with 1113 clinical and non-clinical providers working in public and private hospitals/clinics. Data analysis excludes non-clinical providers reducing sample size to 822. Variables for the analysis are divided into client volume, and training in family planning. Regression models are used to compute the association between training and service use in franchise versus private non-franchise clinics. RESULTS: In franchise clinic networks, staff are 6.5 times more likely to receive family planning training (P = 0.00) relative to private non-franchises. Service use was significantly associated with training (P = 0.00), franchise affiliation (P = 0.01), providers' years of family planning experience (P = 0.02) and the number of trained staff working at government owned clinics (P = 0.00). In this setting, nurses are significantly less likely to receive training compared to doctors (P = 0.00). CONCLUSIONS: These findings suggest that franchises recruit and train various cadres of health workers and training maybe associated with increased service use through improvement in quality of services.

ABSTRACT

The maternal mortality ratio in Pakistan remains high at between 350 and 500 per 100,000 live births, while the neonatal mortality ratio is 50 per 1000 live births. This paper examines the trends in maternal and neonatal mortality in Pakistan and looks at why slow progress has been made in attempts to achieve safe motherhood. Despite numerous initiatives, it is uncertain whether Pakistan will achieve Millennium Development Goals 4 and 5 by 2015.

ABSTRACT

Explanted hearts from patients with chronic left ventricular assist device (LVAD) support have shown the presence of aortic cusp fusion, which results in valvular stenosis and may complicate weaning of a LVAD. This is the first report of aortic cusp fusion diagnosed solely by transesophageal echocardiography (TEE) in vivo in a patient on chronic LVAD support. Under intraoperative TEE guidance, a 41-year-old woman underwent an attempted explantation of a LVAD, which had been implanted 8 months before for dilated cardiomyopathy. When LVAD support was discontinued, previously normal left ventricular function deteriorated, and aortic stenosis from aortic valve cusp fusion was documented by TEE. The explantation procedure was abandoned. This case demonstrates the utility of intraoperative TEE in the evaluation of aortic valvular anatomy and function in patients wtih chronic LVAD support.

ABSTRACT

This paper reviews literature related to morbidity and mortality in South Asian children due to Road Traffic Injuries (RTIs), almost all of which are preventable. In South Asia after males 15-44 years, RTIs are most common in children 0-15 years old. Under-five fatality rates are about six times higher than in the developed world. Most injuries in low income countries occur in urban areas, where pedestrians, passengers, and cyclists account for around 90% of deaths due to RTIs. This higher fatality among pedestrians is probably due to wider traffic mix and lack of safe pedestrian walking areas. The WHO estimates that RTIs cost countries between 1 and 2% of their Gross Domestic Product. This has critical financial consequences. Vital statistics in South Asia are not reliable, and this leads to an underestimation of the magnitude of RTIs that hampers efforts for its acceptance as a preventable public health problem. Rapid urbanization, high motorization rates and failure to institute preventive measures predict a substantial increase in road traffic deaths in the coming years. Creating a safer environment is important. Use of child passenger restraints, bicycle helmets and targeted education campaigns are effective preventive measures. Legislation and implementation of traffic rules and regulations, road engineering and safe pedestrian areas would help reduce injuries. These measures are in accordance with the WHO's five-year strategy to address RTIs worldwide. This strategy includes national and local capacity building, inclusion of RTI in the public health agendas in the world for prevention and control of the health consequences. Child health in South Asia needs to integrate the new challenge of road traffic injuries for the region. It is critical that interventions for reducing this burden are developed, tested and implemented.

ABSTRACT

OBJECTIVES: To determine whether injury prevention counseling and behavioral counseling delivered in the emergency department (ED) could result in increases in self-reported bicycle helmet use. METHODS: The authors undertook a trial of counseling in 222 children recruited in an urban ED between August 2000 and October 2001. All consenting patients in the ED aged 5 to 15 years who did not have life-threatening conditions were eligible. One hundred nine children were assigned to the control group on the basis of attendance on an odd-numbered day, and they received a photocopied photograph of the hospital. One hundred thirteen children were assigned to the intervention group, and they received a personal counseling session and signed a contract promising to wear their bicycle helmets. In addition, 57 of the intervention children were assigned (based on having an even-numbered birthday) to be fitted with helmets if they did not already own them. Parents were telephoned four weeks after the ED encounter for follow-up. RESULTS: Follow-up data were obtained for 148 children (67% follow-up rate), of whom only 69 reported riding a bicycle in the four weeks after their ED visit. Of the final sample of 69 children, 38 belonged to one of the intervention groups, and 25 of these (66%) reported always wearing a helmet while cycling during the four weeks after their ED visit, versus 13 of 31 (42%) in the control group (odds ratio, 2.66; p < 0.05). The effect of the intervention was independent of whether the children owned a helmet at baseline. CONCLUSIONS: Injury prevention counseling in the ED using "The Injury Prevention Program" (TIPP) sheet, behavioral contracting, and helmet distribution may have a significant effect on reports of subsequent bike helmet use.
