Socio-demographic determinants associated with neonatal mortality throughout Algeria based on MICS4 info (2012-2013).
Cholangiocarcinoma (CCA) includes a heterogeneous group of malignancies with limited treatment options. Despite recent advances in medical oncology, the prognosis of CCA patients with metastatic disease remains poor, with a median overall survival of less than a year. In the last decade, notable efforts have been made by the CCA medical community in an attempt to improve clinical outcomes of patients, with the development of molecularly targeted therapies in this setting. Among these treatments, the fibroblast growth factor receptor (FGFR) 2 inhibitor pemigatinib has received accelerated approval in April 2020 by the US Food and Drug Administration (FDA) in CCA patients harboring FGFR2 gene fusions or other rearrangements, on the basis of the results of the FIGHT-202 trial, and thus, representing the first molecularly targeted therapy to be approved for the treatment of CCA. However, several issues remain, including the emergence of polyclonal mutations determining resistance to pemigatinib, the identification of biomarkers predictive of response, and the knowledge gaps regarding the role of other FGFR gene aberrations. This review aims to provide an overview of recent development of pemigatinib, especially focusing on the results of the pivotal FIGHT-202 trial, the approval of this FGFR inhibitor, and the future challenges concerning the use of FGFR-directed treatments in CCA patients.Cetrorelix, a potent third generation of luteinizing hormone releasing hormone (LHRH) antagonist, is a synthetic decapeptide used for treatment of infertility, prostatic hypertrophy and sexual hormone-dependent tumors. The approved drug of cetrorelix (Cetrotide, Asta Medica AG, Frankfurt, Germany.), was used for prevention of premature ovulation in patients undergoing a controlled ovarian stimulation (COS), followed by oocyte pick-up and assisted reproductive techniques, and has been shown safe and effective in controlled ovarian stimulation. Nevertheless, the study of aggregation products of cetrorelix was rarely reported. A simple liquid chromatography mass spectrometry (LC-MS/MS) method was developed for separation, identification and characterization of a new cetrorelix methylene dimer impurity in cetrorelix. The chromatographic separation was achieved on an XSelect Peptide CSH ™C18 column (150 × 4.6 mm, 3.5 μm particle size) using gradient elution with a mobile phase of ammonium formate buffer (pH 3.0, 20 mM), acetonitrile at a flow rate 1.0 mL min-1, and an ultraviolet detection wavelength of 226 nm. The new cetrorelix methylene dimer impurity was characterized by LC-MS/MS and it characteristic fragment ions were summarized. A simple, fast and accurate method was established for the determination of the molecular weight and structure of the new cetrorelix methylene dimer impurity. In this study, the results showed that the cetrorelix was highly unstable in formaldehyde conditions. In addition, it is proposed that the impact of formaldehyde in the environment on the quality of cetrorelix acetate for Injection should be evaluated during the production process.Premature birth (before 37 weeks of gestation) has been linked to a variety of adverse neurological outcomes. Sleep problems are associated with decreased neurocognitive functioning, which is especially common in children born preterm. The exact relationship between prematurity and sleep at school age is unknown. A systematic review is performed with the aim to assess the relationship between prematurity and sleep at school age (5th to 18th year of life), in comparison to sleep of their peers born full-term. Of 347 possibly eligible studies, nine were included. The overall conclusion is that prematurity is associated with earlier bedtimes and a lower sleep quality, in particular more nocturnal awakenings and more non-rapid eye movement stage 2 sleep. Interpretations and limitations of the review are discussed. Moreover, suggestions for future research are brought forward, including the need for a systematic approach with consistent outcome measures in this field of research. A better understanding of the mechanisms that influence sleep in the vulnerable group of children born preterm could help optimize these children's behavioral and intellectual development.
Chronic breathlessness is a frequent symptom in advanced Chronic Obstructive Pulmonary Disease (COPD) and has major impact on quality of life, daily activities and healthcare utilization. Morphine is used as palliative treatment of chronic breathlessness. The aim is to analyze cost-effectiveness of regular, low-dose morphine in patients with advanced COPD from a healthcare and societal perspective.

In a randomized controlled trial, participants with advanced COPD were assigned to 10mg regular, oral sustained-release morphine or placebo twice daily for four weeks. Quality of life (COPD Assessment Test; CAT), quality-adjusted life years (QALY's; EQ-5D-5L), healthcare costs, productivity, and patient and family costs were collected. Incremental cost-effectivity ratio's (ICERs) using healthcare costs and CAT scores, and incremental cost-utility ratio's (ICURs) using societal costs and QALY's were calculated.

Data of 106 of 124 participants were analyzed, of which 50 were in the morphine group (mean [SD] age 65.4 [8.0] years; 58 [55%] male). Both ICER and ICUR indicated dominance for morphine treatment. Sensitivity analyses substantiated these results. From a healthcare perspective, the probability that morphine is cost-effective at a willingness to pay €8000 for an minimal clinically important difference of 2 points increase in CAT score is 63%. selleck compound From a societal perspective, the probability that morphine is cost-effective at a willingness to pay €20,000 per QALY is 78%.

Morphine for four weeks is cost-effective regarding the healthcare and the societal perspective. To estimate the long-term costs and effects of morphine treatment, a study of longer follow-up should be performed.

Chronic pulmonary aspergillosis is a serious complication of nontuberculous mycobacterial pulmonary disease (NTM-PD), and diagnosis remains challenging. The present study examined associations between the respiratory isolation of Aspergillus and the clinical characteristics and treatment outcomes of patients with NTM-PD.

All patients meeting NTM-PD criteria as defined by the ATS/IDSA statement, with at least one respiratory sample cultured for fungi, were included in this retrospective cohort analysis. Patients with at least one respiratory sample isolating Aspergillus were compared to patients who did not isolate Aspergillus. The primary outcomes were culture conversion and radiologic evolution 12 months after NTM-PD treatment initiation.

During a 12 year period, 497 patients meeting the inclusion criteria were seen in our tertiary care center, of whom 130 grew Aspergillus. Median follow up after NTM-PD diagnosis was 46 months. Inhaled corticosteroid use, a nodular-bronchiectatic CT pattern and NTM-PD treatment initiation were more frequent in patients who isolated Aspergillus compared to those who did not (p-value respectively 0.
