Alcoholic cirrhosis remains the second most common indication for liver transplantation.A comprehensive medical and psychosocial evaluation is needed when making a decision to place such patients on the transplant list.Most transplant centers worldwide need a minimum of 6 mo of alcohol abstinence for listing these patients.Patients with alcohol dependence are at high risk for relapse to alcohol use after transplantation(recidivism).These patients need to be identified and require alcohol rehabilitation treatment before transplantation.Recidivism to the level of harmful drinking is reported in about 15%-20%cases.Although,recurrent cirrhosis and graft loss from recidivism is rare,occurring in less than 5%of all alcoholic cirrhosis-related transplants,harmful drinking in the post-transplant pe-riod does impact the long-term outcome.The development of metabolic syndrome with cardiovascular events and de novo malignancy are important contributors to non liver-related mortality amongst transplants for alcoholic liver disease.Surveillance protocols for earlier detection of de novo malignancy are needed to improve the long-term outcome.The need for a minimum of 6 mo of abstinence before listing makes transplant a nonviable option for patients with severe alcoholic hepatitis who do not respond to corticosteroids.Emerging data from retrospective and prospective studies has challenged the 6 mo rule,and beneficial effects of liver transplantation have been reported in select patients with a first episode of severe alcoholic hepatitis who are unresponsive to steroids. 展开更多

The epidemiologic characteristics of 631 infant pertussis cases 〈 12 months, which accounted for 57.42% of the total cases, were analyzed by descriptive epidemiology in Tianjin, between 2010 and 2015. The incidence of infants was 104.66/100,000, which was 118 times higher than in other age groups (P 〈 0.001). The primary type of pertussis simultaneously presented in households was adult-to-infant (70.51%). The parents were identified as the source of infection in 80.18% of cases for infants. The positive rate of placental antibody transfer was 31.06% and 3.13% for 3-month-old infants. Infants presented the highest age-specific pertussis incidence. The most important reason was parents were the important sources of infection, and secondly the lower level of antibodies in neonates and the rapid waning of maternal antibody titer. 展开更多

Introduction: Malnutrition is a major public health problem in Mali, despite the efforts of the government, its technical and financial partners. The aim of this study was to evaluate the integrated management program for acute malnutrition (IMPAM). Methodology: This was a descriptive cross-sectional study that took place from January to December 2020 in the Douentza health district. The study included anyone with at least one malnourished child aged 6 to 59 months in their care who agreed to take part in the study, community health center staff who had given their consent, and the URENI manager at the Douentza reference health center. Data collected via questionnaires were entered into Excel and then analyzed using Epi-Info version 7 software. Results: A total of 138 acutely malnourished children aged 6 - 59 months, including 71 girls (51.45%), 138 accompanying mothers and 11 health workers, were included in our case study. Among the malnourished, 54.34% were in the 12 - 23 months age group and 69.57% had the severe form. 93% of the mothers interviewed were satisfied with the care provided, and all the health staff interviewed stated that community conflicts had an impact on IMPAM’s activities. Cure rates were 81% in Moderate Outpatient Nutritional Recovery and Education Unit (URENAM), 84% in Severe Ambulatory Nutritional Recovery and Education Unit (URENAS) and 92% in Recovery and Intensive Nutritional Education Unit (URENI). Drop-out rates were 19% in URENAM, 16% in URENAS and 0% in URENI. The death rate was 8% in URENI and 0% in URENAM and URENAS. Conclusion: This study confirms the high prevalence of malnutrition in the district (10.54%). It also reveals that factors such as inter-community conflict and insecurity have seriously affected the IMPAM program. 展开更多

Introduction: the problem of Severe Acute Malnutrition (SAM) and its consequences concern and challenge all social actors worldwide. The objective of the study was to identify the real obstacles that actors face in the integrated management of children aged 6 - 59 months suffering from SAM at the University Hospital of Mother and Child (CHUME) and the Chad-China Friendship Hospital (HATC) of N’Djamena. Methodology: this is a cross-sectional descriptive and interpretative study conducted from January to October 2023 at the CHUME and HATC of N’Djamena. It is based on questionnaires and direct observation of two hundred and thirty-six (236) parents or guardians of malnourished children admitted to these health facilities. All 236 agreed to participate freely in this study. Results: it appears from this study that the obstacles to the integrated management of malnourished children were: poor care-care relationship (26.7%) permanent product breaks (22.9%), the direct costs of services ranged from 30,000 to 60,000 FCFA (41.53%), drugs used for the treatment of patients came from the street (66.10%), malaria and anemia occupy an important place (27.5%), 57.2% respondents had monthly income below 60,000 CFAF. Conclusion: the present study carried out has identified the real bottlenecks to the integrated management of children suffering from SAM in the therapeutic nutritional units of the city of N’Djamena. . 展开更多

Introduction: The sixth month appointment (M6) is crucial because at the start of the ART course, it is an indicator of the prognosis of the evolution of care and decision-making on the continuity of treatment. Objective: The objective of this study is therefore to present the profile of People Living with HIV under treatment with Dolutegravir 6 months after starting ART in Kinshasa. Methods: The present study is a cross-sectional view at M6 of a prospective cohort to determine the profile of People Living with HIV (PLHIV) after 6 months of ARV Treatment (ART) in Kinshasa, DRC. During the M6 appointment, from April to August 2022, a sample of 5 ml of blood was taken for the various analyzes from all HIV patients included. The collection of sociodemographic data as well as biological and clinical data was carried out under the same conditions as at inclusion. The parameters recorded during M6 were: age, sex, and religion, level of study, marital status, profession, socio-economic level, height, weight, Body Mass Index (BMI), clinical profile, opportunistic infections as well as biochemical and molecular assessment. Results: In M6, 62 patients were registered including 38 women (61.3%), thus giving a sex ratio of 1.58 in favor of women. Fifty-seven (57) patients did not respond to the appointment, representing a loss rate of 47.89%. The most common age group is between 36 and 45 years old with 16 patients (26.7%). The mean age was 42.4 ± 13.3 years. The mean weight was 60.5 ± 15.4 kg with a mean BMI of 22.6 ± 5.8 kg/m<sup>2</sup>. Thirty-four (34) patients (61.82%) were in Clinical Stage 3. Thirty-six (36) patients (67.92%) had a normal clinical condition. The most common opportunistic infections among patients in M6 were: skin pruritus (25.8%), dermatitis (22.6%) and rash (21%). The mean values of biochemical parameters of patients in M6 were within normal ranges. The median VL value was 2.92 log10 RNA copies/ml with 17.75% of patients experiencing major failure of first-line treatment. Subtype A is dominant wi 展开更多

Background: In accordance with its measles elimination strategic plan 2012-2020, the Democratic Republic of the Congo (DRC) organized a follow-up vaccination campaign against measles from October to December 2019 in 26 provinces. This study aims to establish the contribution of this supplementary vaccination campaign to protecting children against measles. Methods: The survey was carried out in November 2020 among households of the DRC, according to the 2018 revised version of the World Health Organization’s stratified cluster sampling method, using multiple stage sampling. It targeted 280 children aged 6 - 59 months per stratum or province, with 10 children in each of the 28 selected clusters. Data collection using tablets with centralized and real-time data processing was preceded by enumeration to refine the household sampling frame. Clusters and households were selected by random draw. Data collected with CS Pro 7 software were analyzed with SPSS, Epi info 7 and Excel software to determine indicators and make before-after comparisons using the McNemar test, at a precision threshold of 5%. Results: Of the 8535 surveyed children, 89.5% were vaccinatedduring the follow-up campaign and 81.6% were vaccinated before. Only 3.7% had correctly completed campaign vaccination cards. Estimated vaccination coverage increased from 80.8% before the campaign to 92.6% after the campaign (p 0.001). Vaccination coverage after campaign against measles improved in all provinces (p < 0.001) except Bas-Uele and Maniema. Thirteen provinces reached the national coverage target of 95%, compared to five before the campaign. The proportion of zero-dose children dropped significantly after this campaign from 19.2% to 7.4% (p 0.001), and even fell below 1% in six provinces. Conclusion: This measles vaccination campaign improved overall vaccination coverage by 10% and reached more unvaccinated children. Efforts must continue to improve the retention of vaccination card, the adherence of unvaccinated children and the effectiveness of rout 展开更多

Introduction: A higher risk of death is associated with wasting in children if it is not treated properly. The objective of this study was to investigate the ionic disorders observed in infants suffering from severe wasting at Yalgado Ouedraogo Teaching Hospital (YO-TH) and at Charles de Gaulle Pediatric Teaching Hospital (CDG-PTH) in Ouagadougou (Burkina Faso). Methods: This was a retrospective study with a descriptive and analytical aim over the period from January 1, 2016 to December 31, 2020. Results: It concerned infants aged 6 to 24 months hospitalized at YO-TH and at CDG-PTH from Ouagadougou. We included 271 infants. The mean age of the infants was 14.48 ± 5.44 months with 42.07% which was in the age range of [12 - 18] months. On admission to the hospital, the children had an average weight, height and BMI of 6.22 ± 1.32 kg, 0.73 ± 0.07 m and 11.67 ± 1.53 kg/m<sup>2</sup>. In urban areas 56.46% of children and the main reasons for consultation were fever (88.19%), vomiting (52.80%) and diarrhea (50.20%). Electrolyte disturbances in emaciated infants affected all 8 parameters of the blood ionogram. However, the major disorders were 65.68% hyponatremia, 55.35% hypobicarbonatemia, 41.33% hypoprotidemia and 32.47% hypokalemia in infants aged 6 to 24 months. We found an association between diarrhea and residence with hypokalemia (p = 0.0000) and hypochloremia (p = 0.010), respectively. Conclusion: Severe acute wasting in infants 6 to 24 months of age remains a concern in the hospital setting. The frequency of biochemical disturbances is also high. 展开更多

Context: The appointment of the M6 is crucial because it is an indicator of the prognosis of the evolution of the care and the decision-making on the continuation of the AntiRetroViral Treatment. Objective: The objective of this study is therefore to present the virological and molecular profile of People Living with HIV under treatment with Dolutegravir 6 months after being put on ART in Kinshasa. Methods: The present study is a cross-sectional view at the sixth month of a prospective cohort to determine the virological and molecular profile of People Living with HIV (PLHIV) after 6 months of ART based on Dolutegravir (DTG) in Kinshasa. A sample of 5 mL of blood was taken from all HIV patients included. The collection of biological data was carried out under the same conditions as at inclusion. After extraction, Quantitative Real-Time PCR was carried out to determine the quantity of HIV RNA in the samples according to the protocols previously described. Reverse Transcription PCR (RT-PCR) and Nested PCR were carried out to amplify the regions of interest for Protease and Reverse Transcriptase for sequencing. Results: The median VL value was 2.92 log<sub>10</sub> RNA copies/mL. With 17.75% of patients experiencing major failure of first-line treatment. Subtype A is dominant with 13 cases (20.98%);followed by CRF_02AG (16.13%), subtypes C (14.52%), D (9.68%) and K (6.45%). The K65R (3 cases), T69P/N (6 cases), K70R (9 cases) and M184V (8 cases) mutations were listed as existing mutations for Nucleotide Reverse Transcriptase Inhibitors. Conclusion: After 6 months of ART, 59.67% of People Living with HIV on Tenofovir-Lamivudine-Dolutegravir is in therapeutic success while 40.33% are in a state of treatment failure. Subtype A remains dominant in the population of PLHIV. Resistance mutations were detected for Lamivudine and Tenofovir, but none for Dolutegravir. 展开更多

Recurrent caries is a primary reason for restoration failures. The objectives of this study were to synthesize a novel bioactive dental bonding agent containing dimethylaminohexadecyl methacrylate(DMAHDM) and 2-methacryloyloxyethyl phosphorylcholine(MPC) to inhibit biofilm formation at the tooth-restoration margin and to investigate the effects of water-aging for 6 months on the dentin bond strength and protein-repellent and antibacterial durability. A protein-repellent agent(MPC) and antibacterial agent(DMAHDM) were added to a Scotchbond multi-purpose(SBMP) primer and adhesive. Specimens were stored in water at 37 °C for 1, 30, 90, or 180 days(d).At the end of each time period, the dentin bond strength and protein-repellent and antibacterial properties were evaluated. Protein attachment onto resin specimens was measured by the micro-bicinchoninic acid approach. A dental plaque microcosm biofilm model was used to test the biofilm response. The SBMP + MPC + DMAHDM group showed no decline in dentin bond strength after water-aging for 6 months, which was significantly higher than that of the control(P < 0.05). The SBMP + MPC + DMAHDM group had protein adhesion that was only 1/20 of that of the SBMP control(P < 0.05). Incorporation of MPC and DMAHDM into SBMP provided a synergistic effect on biofilm reduction. The antibacterial effect and resistance to protein adsorption exhibited no decrease from 1 to 180 d(P > 0.1). In conclusion, a bonding agent with MPC and DMAHDM achieved a durable dentin bond strength and long-term resistance to proteins and oral bacteria. The novel dental bonding agent is promising for applications in preventive and restorative dentistry to reduce biofilm formation at the tooth-restoration margin. 展开更多

The association between Leisure Time Physical Activity (LTPA) during pregnancy and foetal outcomes has been extensively investigated. However, epidemiological studies specifically referred to LPTA in the last months of pregnancy are scarce. We evaluated the association between LPTA and the risk of both preterm delivery and small for gestational age (SGA) during the last three months of pregnancy in Italy. A nationwide case-control study was performed in nine Italian cities. A total of 299 preterm delivery, 364 SGA and 855 controls were enrolled in the study. A self-administered questionnaire was used to assess socio-demographic variables, medical and reproductive history, life-style habits and LTPA referred to the last three months of pregnancy. Univariate and multivariate regression analyses were performed in order to estimate Odds ratios and 95% CI. LTPA during the last three months of pregnancy decreases the risk of preterm delivery (adjusted OR = 0.56;95% CI 0.39 - 0.79). Among the different types of physical activity, walking, the most frequently referred activity, appears significantly protective against preterm delivery (adjusted OR = 0.53;95% CI 0.36 - 0.81). Moreover, a small protective effect of walking was evidenced against SGA (adjusted OR = 0.72;95% CI 0.51 - 1.00). In conclusion, a mild physical activity such as walking in the last three months of pregnancy seems to reduce the risk of preterm delivery and, at a lesser extent, of SGA, confirming the beneficial effects of physical activity along the whole pregnancy. 展开更多

The Tlemcen region is located in north-western Algeria and is characterized by a semi-arid bioclimate. An approach to the diversity of the malacofauna associated with Salvia officinalis was carried out in three stations belonging to this area from February to June 2015. The specific richness of the Gastropods is 9 divided into three families: Milacidae, Helicidae and Subulinidae. The second includes two subfamilies including that of Helicinae and that of Helicellinae. Two species are constant, 01 is incidental and the 06 others are very accidental. The relative importance of snails fluctuates according to the stations and according to the months and the seasons. In winter, in the first station the malacological richness is equal to 6. In February, the specific richness is relatively important in the 2nd station with a value equal to 7. Milax nigricans (Milacidae) has a frequency of 10% in station 1 and has a density of 0.1 in this same station. It is absent in the other two stations. Euparypha pisana has a frequency of 60% in station 3 and an abundance of 0.57 in this same station. 展开更多

With the OLR data, the landfall and activity of tropical cyclones (TC) in southern China over a 20-year period (1975~1994) are studied. The result shows that the variation of the monthly anomalous OLR is somewhat teleconnected with the TC activity in southern China. The former is used to predict short-term climate for the latter over months with frequent or no TC influence. To some extent, the relationship between the TC activity in southern China and the monthly mean OLR anomalies is dependent on the climatological location of the subtropical high in northwestern Pacific region. 展开更多
