Exclusive Enteral Nutrition for the Treatment of Pediatric Crohn’s Disease: The Patient Perspective / 대한소아소화기영양학회지

Crohn’s disease (CD) is a chronic, incurable and relapsing disease involving any part of the gastrointestinal tract and exclusive enteral nutrition (EEN) is first-line therapy. Few studies have examined the patient experience of EEN. The aim of this study was to assess the child’ s experiences of EEN, to identify problematic themes and understand the child’s mindset. Children with CD who previously completed EEN were recruited to complete a survey. All data were analyzed using Microsoft Excel and reported as N (%). Forty-four children (mean age 11.3 years) consented to participate. Sixty-eight percent of children reported limited formula flavors as the most challenging aspect and 68% of children identified ‘support’ to be important. This study highlights the psychological impact of chronic disease and its therapies on children. Providing adequate support is essential to insure EEN is successful. Further studies are required to determine psychological support strategies for children taking EEN.

Normal ultrasonographic dimensions of the gallbladder and common bile duct in neonates

Background: Ultrasound (US) is the first choice of imaging in neonates presenting with persistent jaundice to exclude surgically correctable causes and differentiate obstructive from nonobstructive causes. Previous studies on normal dimensions of gallbladder (GB) and common bile duct (CBD) recruited adults and children spread across a wide age group.Aims: This study aimed to determine GB and CBD normal dimensions in a large homogeneous neonatal population as well as guide decision regarding pre-US fasting in neonates who require GB evaluation.Materials and Methods: Five hundred and twenty-eight healthy newborns were recruited between May 2009 and May 2011. The widest intraluminal anterior-posterior diameters of GB and CBD were measured. Neonatal age in days, sex, birth weight, weight and height, gestational age at delivery, and time interval since last feed recorded.Results: The mean age was 9.56 ± 7.66 days, and 50.6% were males. The mean CBD diameter was 1.16 ± 1.61 mm while the mean GB diameter was 4.42 ± 2.16 mm. GB and CBD were clearly seen and measurable in 297 (55.8%) neonates and 237 (44.38%) neonates, respectively. There was a significant correlation between CBD diameter and GB diameter (P = 0.04) but no correlation with any demographic parameter. GB visualization was not dependent on time interval from last feed.Conclusion: Mean neonatal values for CBD and GB were established, but neonates have a wider range of GB diameters compared with older children, so GB diameter may not be a reliable parameter for neonatal GB pathologies. GB visualization was not dependent on time interval from last feed; hence, a recent feed should not delay emergency scans, especially in ill neonates

Quality of Life after post-prostatectomy intensity modulated radiation therapy to the prostate bed with or without the use of gold fiducial markers for image guidance or higher total radiotherapy doses

ABSTRACT Purpose To evaluate quality of life (QoL) after post-prostatectomy intensity modulated radiation therapy (IMRT) in the "adjuvant" setting starting within 4 months of radical prostatectomy for adverse features; and "salvage" setting for a PSA≥0.2ng/mL. Materials and Methods Retrospective review of 130 patients who underwent IMRT to the prostate bed±gold fiducial marker placement for image guidance to 64.8-72.0Gy (median, 70.2Gy) between 2004 and 2013. Higher doses were defined as 70.2-72.0Gy and lower doses were defined as 64.8-68.4Gy. Androgen deprivation therapy (ADT) was given to 4/48 (8%) adjuvant patients and 9/82 (11%) salvage patients. International Prostate Symptom Score (IPSS), Sexual Health Inventory for Men (SHIM), and Expanded Prostate Cancer Index Composite-26-bowel (EPIC-26-bowel) questionnaires were used to assess urinary, sexual, and bowel QoL, respectively. Results Median follow-up was 46 months. There were better urinary (p=0.03) and sexual (p=0.002) QoL scores with adjuvant IMRT relative to salvage IMRT. The use of prostate bed fiducial markers did not significantly affect urinary, sexual, or bowel QoL (p=0.39, p=0.49, and p=0.40, respectively). Higher total radiotherapy doses did not significantly affect urinary, sexual, or bowel QoL (p=0.21, p=0.61, and p=0.36, respectively). Conclusions There was no significant change in urinary, sexual, and bowel sexual QoL with post-prostatectomy IMRT regardless of whether prostate bed fiducial markers or higher total radiotherapy doses were used. QoL with IMRT in the present study compares favorably with prior reports for three-dimensional conformal radiation therapy.

Depressão pós-parto e satisfação conjugal: impacto longitudinal em uma amostra brasileira / Postpartum depression and marital satisfaction: a longitudinal study in a Brazilian sample / Depresión posparto y satisfacción con la relación de pareja: impacto longitudinal en una muestra brasileña

Objetivo: O objetivo deste trabalho foi verificar a relação entre a satisfação conjugal e a depressão pós-parto e o impacto destas variáveis nos níveis de satisfação conjugal e depressão futuros, em uma amostra brasileira. Estudos revelam que o conflito conjugal é um antecedente importante no desenvolvimento da depressão e que a depressão pós-parto influencia significativamente a satisfação conjugal. Métodos: Este estudo longitudinal com 99 mulheres brasileiras utilizou análises de regressão múltipla para verificar a associação entre a satisfação conjugal e a depressão. A sintomatologia depressiva foi avaliada pelo instrumento Self-Reporting Questionnaire (SRQ-20). A satisfação conjugal foi verificada a partir de itens sobre a percepção de satisfação conjugal das participantes. Os dados foram coletados 4 meses e 2 anos após o parto. Os dados longitudinais possibilitaram a análise cronológica da interação entre as duas variáveis. Resultados e Conclusões: Os resultados indicam que o modelo teórico que estabelece a relação entre conflito conjugal e depressão é também apropriado para casais brasileiros, sugerindo a utilização potencial da terapia de casal no tratamento da depressão pós-parto no Brasil.

Objective: This study examined the relationship between marital satisfaction and postpartum depression as well as the impact of postpartum depression and marital satisfaction on later relational characteristics among Brazilian couples. Studies have shown that marital satisfaction is an important antecedent to depression and that postpartum depression has an influence on marital satisfaction. Methods: A longitudinal study using multiple regression to test the association between marital satisfaction and depression was conducted among Brazilian women. Depressive symptomatology was assessed using the Self-Reporting Questionnaire 20 and marital satisfaction using an instrument developed by the researchers to test the individuals' perception of their marital quality. Data were collected at 4 months and 2 years after childbirth. The longitudinal data allowed researchers to chronologically analyze the interaction of key variables. Results and Conclusions: Results showed that the model established between marital satisfaction and depression is appropriate for Brazilian couples as well as for postpartum women. This study highlights the potential impact of marital treatment on postpartum depression in Brazil.

To evaluate dosimetric coverage of the prostate, normal tissue sparing, and acute toxicity with HDR brachytherapy for large prostate volumes.

Quality of life after high-dose-rate brachytherapy monotherapy for prostate cancer

Purpose There is little information in the literature on health-related quality of life (HRQOL) changes due to high-dose-rate (HDR) brachytherapy monotherapy for prostate cancer. Materials and Methods We conducted a prospective study of HRQOL changes due to HDR brachytherapy monotherapy for low risk or favorable intermediate risk prostate cancer. Sixty-four of 84 (76%) patients who were treated between February 2011 and April 2013 completed 50 questions comprising the Expanded Prostate Cancer Index Composite (EPIC) before treatment and 6 and/or 12 months after treatment. Results Six months after treatment, there was a significant decrease (p<0.05) in EPIC urinary, bowel, and sexual scores, including urinary overall, urinary function, urinary bother, urinary irritative, bowel overall, bowel bother, sexual overall, and sexual bother scores. By one year after treatment, EPIC urinary, bowel, and sexual scores had increased and only the bowel overall and bowel bother scores remained significantly below baseline values. Conclusions HDR brachytherapy monotherapy is well-tolerated in patients with low and favorable intermediate risk prostate cancer. EPIC urinary and sexual domain scores returned to close to baseline 12 months after HDR brachytherapy. .

Stage IIA and IIB testicular seminoma treated post-orchiectomy with radiation therapy versus other approaches: a population-based analysis of 241 patients

Objectives To evaluate post-orchiectomy utilization of radiation therapy (RT) versus other management approaches in stage IIA and IIB testicular seminoma patients. Materials and Methods Two hundred and forty-one patients with stage IIA and IIB testicular seminoma were identified between 1988 and 2003 using the Surveillance, Epidemiology, and End Results (SEER) database. Results Median follow-up was 10 years. Patients with stage IIA disease underwent RT more frequently than those with stage IIB disease (72% vs. 46%, respectively; P<0.001). There was no significant change in RT utilization for stage IIA or IIB disease between 1988 and 2003 (P = 0.89). Conclusions Between 1988 and 2003, stage IIA patients underwent RT more often than stage IIB patients in the United States. There was no significant change in RT utilization for stage IIA or IIB disease during this time period. Based on reports describing excellent progression-free survival with cisplatin-based chemotherapy, this approach has increased in popularity since 2003 and may eventually become the most popular treatment approach for both stage IIA and IIB testicular seminoma. .

Prevalence of Anemia and Its Risk Factors among Pregnant Women in Dakar and Fatick Regions, Senegal.

Objectives: Iron Folic acid supplementation (IFAS) during pregnancy has been implemented in Senegal for many years. However, prevalence of anemia is still high among pregnant women. To provide data for program improvement, we conducted a study to assess the prevalence of anemia and associated risk factors in Dakar and Fatick regions. Methods: The study was a cross-sectional, descriptive survey of 483 randomly selected pregnant women in Dakar and Fatick regions. Hemoglobin level was determined by HemoCue photometer, and questionnaires were used to collect data on socio-economic characteristics, knowledge, attitudes, and practices. Data were cleaned, coded and analyzed with Epi Info. Financial barriers were defined as: family decision makers who restrict expenditures, limited financial resources. Results: Results showed that the prevalence of anemia (Hb <11g/dL) among pregnant women was 66.4% and 71.4% in Dakar and Fatick regions, respectively. Pregnant women had lower risks of being anemic when they had an income-generating activity (OR=1.63, CI (1.1 - 2.5)), had been supplemented for at least 90 days (OR=2.26, CI (1.2 - 4.3)), and had no financial barrier to access IFAS (OR=0.40, CI (0.1 - 0.9]. 50% of the pregnant women wrongly associated side effects to IFA consumption and consequently initiated IFAS after the 2nd trimester. Conclusions: Anemia is a severe public health problem among pregnant women in these two regions. Interventions designed to address anemia should improve accessibility to IFAS through promotion of early initiation of IFAS during pregnancy and distribution of free IFAS.

External beam radiation therapy and a low-dose-rate brachytherapy boost without or with androgen deprivation therapy for prostate cancer

Purpose To assess outcomes with external beam radiation therapy (EBRT) and a low-dose-rate (LDR) brachytherapy boost without or with androgen deprivation therapy (ADT) for prostate cancer. Materials and Methods From January 2001 through August 2011, 120 intermediate-risk or high-risk prostate cancer patients were treated with EBRT to a total dose of 4,500 cGy in 25 daily fractions and a palladium-103 LDR brachytherapy boost of 10,000 cGy (n = 90) or an iodine-125 LDR brachytherapy boost of 11,000 cGy (n = 30). ADT, consisting of a gonadotropin-releasing hormone agonist ± an anti-androgen, was administered to 29/92 (32%) intermediate-risk patients for a median duration of 4 months and 26/28 (93%) high-risk patients for a median duration of 28 months. Results Median follow-up was 5.2 years (range, 1.1-12.8 years). There was no statistically-significant difference in biochemical disease-free survival (bDFS), distant metastasis-free survival (DMFS), or overall survival (OS) without or with ADT. Also, there was no statistically-significant difference in bDFS, DMFS, or OS with a palladium-103 vs. an iodine-125 LDR brachytherapy boost. Conclusions There was no statistically-significant difference in outcomes with the addition of ADT, though the power of the current study was limited. The Radiation Therapy Oncology Group 0815 and 0924 phase III trials, which have accrual targets of more than 1,500 men, will help to clarify the role ADT in locally-advanced prostate cancer patients treated with EBRT and a brachytherapy boost. Palladium-103 and iodine-125 provide similar bDFS, DMFS, and OS. .

Comparison of DNA Extraction Methods for Human Oral Microbiome Research.

The oral micro biome is highly diverse and its composition is associated with oral disease and potentially diseases at other sites. Our objective is to evaluate DNA extraction methods potentially suitable for population-based investigations on the oral human microbiome and disease risk. Six commonly used microbial DNA extraction kits, employing either enzymatic methods or mechanical bead beating for cell lysis, were evaluated for the following aspects total DNA yield and quality and 16s rRNA DNA product and representation of microbial diversity. All analyses were carried out using a pooled and homogenized sample from one study subject. 16s rRNA gene sequence data were processed using the QIIME pipeline. One way ANOVA and Kruskal-Wallis tests were used to compare the different DNA extraction methods. We found that enzymatic extraction kits produced higher human genomic DNA, compared with mechanical extraction kits, however, phylogenic diversity in oral microbiome community structure from 16s rRNA gene sequence reads revealed no important differences between kit types. Enzymatic and mechanical bead beating kits provide alternative approaches for DNA extraction of oral microbiome DNA from oral wash samples. Greater total DNA yields are found in enzymatic approaches but microbial diversity can be similarly well characterized by either enzymatic or mechanical bead beating approaches.

Lipiodol as a Fiducial Marker for Image-Guided Radiation Therapy for Bladder Cancer

Purpose To evaluate Lipiodol as a liquid, radio-opaque fiducial marker for image-guided radiation therapy (IGRT) for bladder cancer.Materials and Methods Between 2011 and 2012, 5 clinical T2a-T3b N0 M0 stage II-III bladder cancer patients were treated with maximal transurethral resection of a bladder tumor (TURBT) and image-guided radiation therapy (IGRT) to 64.8 Gy in 36 fractions ± concurrent weekly cisplatin-based or gemcitabine chemotherapy. Ten to 15mL Lipiodol, using 0.5mL per injection, was injected into bladder submucosa circumferentially around the entire periphery of the tumor bed immediately following maximal TURBT. The authors looked at inter-observer variability regarding the size and location of the tumor bed (CTVboost) on computed tomography scans with versus without Lipiodol.Results Median follow-up was 18 months. Lipiodol was visible on every orthogonal two-dimensional kV portal image throughout the entire, 7-week course of IGRT. There was a trend towards improved inter-observer agreement on the CTVboost with Lipiodol (p = 0.06). In 2 of 5 patients, the tumor bed based upon Lipiodol extended outside a planning target volume that would have been treated with a radiation boost based upon a cystoscopy report and an enhanced computed tomography (CT) scan for staging. There was no toxicity attributable to Lipiodol.Conclusions Lipiodol constitutes a safe and effective fiducial marker that an urologist can use to demarcate a tumor bed immediately following maximal TURBT. Lipiodol decreases inter-observer variability in the definition of the extent and location of a tumor bed on a treatment planning CT scan for a radiation boost.

Schistosomiasis and soil-transmitted helminth infections in school children in the Lake Mainit area in Northeastern Mindanao: An opportunity for integrated helminth control in the school setting

OBJECTIVES:This study aimed to determine the epidemiologic status of schistosomiasis and soil-transmitted helminth (STH) infections in the Lake Mainit area in Northeastern Mindanao. METHODS: School children from the municipalities of Alegria and Mainit in Surigao del Norte, and Jabonga and Kitcharao in Agusan del Norte were targeted as participants. Stools were collected, processed through Kata Katz method, and examined. Data gathered were double-encoded and processed to derive parasitologic parameters that were used to categorize the municipalities based on the World Health Organization guidelines. RESULTS:The overall prevalence of schistosomiasis was 10.9%, while the prevalence of heavy intensity infections was 0.1%. Alegria and Mainit were classified as moderate-risk communities, while Jabonga and Kitcharao were classified as low-risk communities. The overall cumulative prevalence of STH infections was 43.9%, while prevalence of heavy intensity infection was 12.7% Jabonga and Kitcharao were classified as Category I communities, while the reset were classified as Category III. CONCLUSION:There is a need to consider implementation of school-based Mass Drug Administration (MDA) for schistosomiasis control in the same manner as in the implementation of MDA for STH control. Multisectoral involvement is necessary for integration of efforts in addressing the parasitic diseases as public health concerns in the area.

Cashew nut extract (De BCC) in the treatment of basal cell carcinoma

PURPOSE OF THE STUDY: Basal cell carcinoma (BCC) remains as the most common cutaneous neoplasm in the Philippines consisting of more than 60% of all skin cancers. Anacardium occidentale (Linn.) cashew extract, which had been used successfully in the removal of warts and moles in previous studies, is presented as a therapeutic option in BCC. METHODS: An open-label prospective study was conducted on 36 patients (mean age of 65 years) with documented BCC lesions on middle third of the face. Cashew nut extract (DeBCC) application was offered to these patients as an alternative option to very unacceptable extirpative surgery offered by general and plastic surgeons as treatment for their lesions. Lesion size ranged from 7.5- 64 mm. (26.26 mm). Topical treatment was applied every 1-2 weeks, as needed. Follow-up examinations with photographic documentation were made every week to evaluate success of the treatment. RESULTS: After a mean of 7 treatment applications (range of 1-20) all the lesions were undetectable on clinical examinations. Mild tingling sensation, which was reported by all patients during the treatment applications, was tolerable on all occasions. With follow-up ranging from 5-60 months (38.72 months), 16 patients completed the planned 5 - year post-treatment follow-up period. There were no recurrences detected. CONCLUSIONS: Anacardium occidentale (Linn.) cashew extract (DeBCC) presents a viable and acceptable treatment option in primary BCC. The importance of this treatment option could be stressed in patients with lesions not amenable to the prescribed wide margin of resection needed in surgery.

Household pasteurization of drinking-water: the chulli water-treatment system.

A simple flow-through system has been developed which makes use of wasted heat generated in traditional clay ovens (chullis) to pasteurize surface water. A hollow aluminium coil is built into the clay chulli, and water is passed through the coil during normal cooking events. By adjusting the flow rate, effluent temperature can be maintained at approximately 70 degrees C. Laboratory testing, along with over 400 field tests on chulli systems deployed in six pilot villages, showed that the treatment completely inactivated thermotolerant coliforms. The chulli system produces up to 90 litres per day of treated water at the household level, without any additional time or fuel requirement. The technology has been developed to provide a safe alternative source of drinking-water in arsenic-contaminated areas, but can also have wide application wherever people consume microbiologically-contaminated water.

Crystal habits and magnetic microstructures of magnetosomes in coccoid magnetotactic bacteria

Nós relatamos a aplicação de holografia não-axial e microscopia eletrônica de alta resolução para estudar os hábitos cristalinos de magnetossomos e a microestrutura magnética de dois morfotipos de cocos de bactérias magnetotáticas coletadas em uma lagoa salobra em Itaipu, Brasil. Itaipu-1, o organismo cocóide maior, contémduas cadeias separadas de magnetossomos atipicamente grandes; os cristais dos magnetossomos possuem projeções aproximadamente quadradas, comprimentos deaté 250 nm e são ligeiramente alongados na direção [111] (razão largura/comprimento de aproximadamente 0.9).Os cristais dos magnetossomos em Itaipu-3 possuemcomprimentos até 120 nm, maior alongamento na direção [111] (largura/comprimento ~ 0.6), e proeminentes facetas nas extremidades. Os resultados mostram que os hábitos cristalinos dos magnetossomos em Itaipu-1 eItaipu-3 são relacionados, diferindo apenas nos tamanhos relativos das suas faces cristalinas. Em ambos os casos, os cristais são alinhados com seus eixos de alongamento [111] paralelos à direção da cadeia. Em Itaipu-1, mas não em Itaipu-3, o posicionamento cristalográfico, perpendicular à direção [111], de cristais sucessivos na cadeia de magnetossomos parece estar sobre controlebiológico. Enquanto os magnetossomos grandes em Itaipu-1 são monodomínios magnéticos metaestáveis, em Itaipu-3 eles são monodomínios magnéticos permanentes como na maioria das bactérias.
