Status of c.ngenital Heart Defec.s in Nigeria: The Role of c.rdiac.Surgery

World Journal of c.rdiovasc.lar Surgery 2019年第7期9卷 63-72页

作者： Ikec.ukwu A. Nwafor john c. eze National c.rdiothorac.c.c.nter of Exc.llenc. University of Nigeria Teaching Hospital Ituku-Ozalla Nigeria

Bac.ground: Unlike in developed c.untries, the delivery of c.rdiovasc.lar servic.s to c.ildren born with c.ngenital heart defec.s in Nigeria is inadequate. There are problems at both pediatric.and adult ages with high morbidity and mortality on ac.ount of inadequate surgic.l c.re. Objec.ive: To determine the status of c.ngenital defec.s and assess the impac. of foreign c.rdiac.missionary missions vis-à-vis the effec.s on the magnitude as well as on the educ.tional program for the loc.l c.rdiac.team. Materials and Method: In the last 5.5 years, Foreign c.rdiac.Surgery missions were reinstituted at National c.rdiothorac.c.c.nter of Exc.llenc., Enugu, Nigeria. The partic.pants performed c.rdiac.interventions on a variety of patients with c.D. We performed a retrospec.ive review of this endeavor. Patients’ demographic., number of patients, age ranges, types of c.D and c.inic.l evaluation methodology were obtained from our hospital’s rec.rd department. We also assessed types of c.rdiac.interventions, outc.me and c.allenges and the impac.s of the foreign c.rdiac.surgery missions. Results:?During the study period, a total of 72 c.ildren with c.D were evaluated. They were 39 males and 33 females. The age ranged between 0 - 10 years in c.ildren and 41 - 50 years in the adult. We studied both simple and c.mplex anomalies. A VSD was the c.mmonest (n = 22, 27.16%). c.nc.usion: Foreign c.ngenital c.rdiac.surgery missions were not able to provide adequate servic.s for the c.re of c.D that require c.rdiac.surgery both in terms of reduc.ion in magnitude as well as adequate educ.tional program for the loc.l c.rdiac.team. Thus infants, in partic.lar, suffer an early death. The need for governmental support to develop a c.mprehensive program to c.re for these patients is essential in Nigeria and other developing c.untries.

Bac.ground and Objec.ive: Voc.l c.rd paralysis results in impairment of breathing and/or speec.. One of the c.uses of voc.l c.rd paralysis is the disruption of vagus nerve innervation to the voc.l c.rds by the mass effec. of a neighbouring struc.ure. We report a rare c.se of voc.l c.rd paralysis sec.ndary to internal c.rotid artery dissec.ion. Method: The diagnosis was based on c.inic.l history, physic.l examination and imaging studies. Literature review was done. c.se Report: This was a 53-year-old female with a history of unremitting, progressive hoarseness and mild dysphagia to liquid, who was c.inic.lly found to have impaired left voc.l c.rd mobility, a left-sided pulsatile nec. mass and left c.rotid artery dissec.ion based on imaging studies. Symptoms abated after c.nservative treatment with Aspirin and she has remained symptom free sinc. two years of follow-up. c.nc.usion: Voc.l c.rd paralysis c.n be a c.nsequenc. of c.rotid artery dissec.ion c.using mass effec. on the vagus nerve. Thus, c.rotid artery dissec.ion should not be forgotten as a possible c.use of voc.l c.rd paralysis in some c.ses of voc.l c.rd paralysis of unc.rtain etiology. Treatment with anti-platelet drug c.n bring about resolution of symptoms and return of voc.l c.rd mobility.

c.arac.erization of Small-Sc.le Farmers and Assessment of Their Ac.ess to c.op Produc.ion Information in Selec.ed c.unties of Kenya

引用

Agric.ltural Sc.enc.s 2024年第5期15卷 565-589页

作者： Anastasia Mumbi Wahome john B. K. Kiema Galc.no c. Mulaku Isaac.Mukoko Department of Geospatial & Spac. Tec.nology University of Nairobi Nairobi Kenya Department of Public.Health Kenya Methodist University Nairobi Kenya

Small-sc.le farming ac.ounts for 78% of total agric.ltural produc.ion in Kenya and c.ntributes to 23.5% of the c.untry’s GDP. Their c.op produc.ion ac.ivities are mostly rainfed subsistenc. with any surplus being sold to bring in some inc.me. Timely dec.sions on farm prac.ic.s suc. as farm preparation and planting are c.itic.l determinants of the seasonal outc.mes. In Kenya, most small-sc.le farmers have no reliable sourc. of information that would help them make timely and ac.urate dec.sions. c.unty governments have extension offic.rs who are mandated with giving farmers advisory servic.s to farmers but they are not able to reac. most farmers due to fac.litation c.nstraints. The mode and format of sharing information is also c.itic.l sinc. it’s important to ensure that it’s timely, well-understood and usable. This study sought to assess ac.ess to geospatial derived and other c.op produc.ion information by farmers in four selec.ed c.unties of Kenya. Spec.fic.objec.ives were to determine the profile of small-sc.le farmers in terms of age, educ.tion and farm size;to determine the type of information that is made available to them by c.unty and Sub-c.unty extension offic.rs inc.uding the format and mode of provision;and to determine if the information provided was useful in terms of ac.urac., timeliness and adequac.. The results indic.ted that over 80% of the farmers were over 35 years of age and over 56% were male. Majority had attained primary educ.tion (34%) or sec.ndary educ.tion (29%) and most farmers in all the c.unties grew maize (71%). Notably, fellow farmers were a sourc. of information (71%) with the frequenc. of sharing information being mostly seasonal (37%) and when information was available (43%). Over 66% of interviewed farmers indic.ting that they fac.d c.allenges while using provided information. The results from the study are insightful and helpful in determining effec.ive ways of providing farmers with useful information to ensure maximum benefits.

Alex Ekwueme Federal University Teaching Hospital Abakaliki Ebonyi State Nigeria

Bac.ground: Inadequate antenatal c.re, both in c.verage and standard, has been linked with poor pregnanc. outc.mes. In a resourc. poor setting, home delivery is c.nsidered very c.eap, but the possible outc.me of suc. pregnanc.es has been a subjec. of interest. This study evaluated the assoc.ation of booking status with pregnanc. outc.mes. Objec.ives: To examine the fac.ors that influenc. booking and impac. of the booking status on pregnanc. outc.mes. Methods: This was a hospital-based prospec.ive c.hort study of 240 (120 booked and 120 un-booked) pregnant mothers selec.ed through systematic.random sampling. The study was c.rried out at the Department of Obstetric. and Gynaec.logy, Alex Ekwueme Federal University Teac.ing Hospital Abakaliki, Nigeria. c.i-square test, t-test and logistic.regression were used for analysis. Results: The mean age of the partic.pants was 30.39 ± 5.05 years and 29.05 ± 6.36 years respec.ively for the booked and unbooked. Marital status (OR = 6.35, 95% c. = 1.24 - 32.59), educ.tional status (OR = 36.40, 95% c. = 5.26-152.83), plac. of residenc. (OR = 0.15, 95% c. = 0.06 - 0.41), partner’s support (OR = 0.05, 95% c. = 0.01 - 0.37), family support (OR = 0.03, 95% c. = 0.01 - 0.13), mode of delivery (OR = 0.23, 95% c. = 0.12 - 0.46), APGAR sc.re in first minute (OR = 6.02, 95% c. = 2.45 - 14.83) and NBIc. admission (OR = 3.75, 95% c. = 1.67 - 8.43) were assoc.ated with booked status. However, being unmarried, nulliparity/grandmultiparity, low level of educ.tion, blue c.lar jobs, low inc.me, rural dwelling and poor partner and poor family support were assoc.ated with the unbooked. The booked parturients had a better perinatal outc.me c.mpared the unbooked. c.nc.usion/Rec.mmendation: There was high prevalenc. of operative deliveries, perinatal morbidity and mortality among the unbooked mothers. Girl c.ild educ.tion, employment and poverty alleviation would improve antenatal c.re utilization.

Ekpe Wendy Oliobi Emmanuel c. Uwakwe Department of Obstetric. and Gynaec.logy Alex Ekwueme Federal University Teaching Hospital AbakalikiNigeria

Bac.ground: Episiotomy is a very c.mmon obstetric.surgery, and it c.uld be assoc.ated with serious c.mplic.tions. However, these c.mplic.tions largely are not notic.d due to the shift of attention from mother to baby, after a suc.essful delivery. Objec.ive: To identify the morbidities assoc.ated with episiotomies and fac.ors assoc.ated with suc. morbidities. Method: This was a questionnaire based c.oss sec.ional desc.iptive study among women who attended the Obstetric.Department of Alex Ekwueme Federal University Teac.ing Hospital Abakaliki Ebonyi State, between 1st July and 31st Nov, 2023. The study population c.nsisted of parturients who had episiotomies in their previous c.nfinements, attending either the antenatal c.inic.or the postnatal c.inic.at Alex Ekwueme Federal University Teac.ing Hospital Abakaliki Ebonyi State. Results: Mac.osomia was the most c.mmon indic.tion of episiotomy at a rate of 31.6%. The majority of episiotomies were performed on the parturients in their first c.nfinement at a rate of 64.5% and the majority of repairs were performed by the Registrar at a rate of 65.0%. Informed c.nsent was obtained from 45.79% of parturients while 54.21% were not informed before the episiotomy was administered. Only 55.3% of the parturient rec.ived analgesia before episiotomy was administered. The majority of the parturients had their episiotomy repaired between 10 - 15 minutes at a rate of 40.3%. Postoperative pain at the rate of 44.5% was the most c.mmon c.mplic.tion and dyspareunia as a form of sexual c.mplic.tion was the c.mmonest at a rate of 31.3%. c.nc.usion: The parturient needs to be properly c.unselled before administration of episiotomy and adequate analgesia should be given, as episiotomy is a surgic.l proc.dure. Proper training of health workers on both the tec.nique of administering and repairing episiotomy is important. Restric.ive use of routine episiotomy in primigravidae is advised to reduc. the rate of episiotomy.

Evaluation of a Wireless Solar Powered Personal Weather Station

引用

Agric.ltural Sc.enc.s 2024年第1期15卷 36-53页

作者： Robert J. Lasc.no Timothy S. Goebel Dennis c. Gitz III john E. Stout c.opping Systems Researc. Laboratory Wind Erosion and Water Conservation Research Unit USDA-ARS Lubbock TX USA

We are evaluating dryland c.tton produc.ion in Martin c.unty, Texas, measuring c.tton lint yield per unit of rainfall. Our goal is to c.llec. rainfall data per 250 - 400 ha. Upon selec.ion of a rainfall gauge, we realized that the c.st of using, for example, a tipping buc.et-type rain gauge would be too expensive and thus searc.ed for an alternative method. We selec.ed an all-in-one c.mmerc.ally available weather station;hereafter, referred to as a Personal Weather Station (PWS) that is both wireless and solar powered. Our objec.ive was to evaluate average measurements of rainfall obtained with the PWS and to c.mpare these to measurements obtained with an automatic.weather station (AWS). For this purpose, we installed four PWS deployed within 20 m of the Plant Stress and Water c.nservation Meteorologic.l Tower that was used as our AWS, loc.ted at USDA-ARS c.opping Systems Researc. Laboratory, Lubboc., TX. In addition, we measured and c.mpared hourly average values of short-wave irradianc. (Rg), air temperature (Tair) and relative humidity (RH), and wind speed (WS), and c.lc.lated values of dewpoint temperature (Tdew). This c.mparison was done over a 242-day period (1 Oc.ober 2022-31 May 2023) and results indic.ted that there was no statistic.l differenc. in measurements of rainfall between the PWS and AWS. Hourly average values of Rg measured with the PWS and AWS agreed on c.ear days, but PWS measurements were higher on c.oudy days. There was no statistic.l differenc. between PWS and AWS hourly average measurements of Tair, RH, and c.lc.lated Tdew. Hourly average measurements of Rg and WS were more variable. We c.nc.uded that the PWS we selec.ed will provide adequate values of rainfall and other weather variables to meet our goal of evaluating dryland c.tton lint yield per unit rainfall.
