Challenges in reducing maternal and neonatal mortality in Niger: an in-depth case study.

INTRODUCTION: Recent modelled estimates suggest that Niger made progress in maternal mortality since 2000. However, neonatal mortality has not declined since 2012 and maternal mortality estimates were based on limited data. We researched the drivers of progress and challenges. METHODS: We reviewed two decades of health policies, analysed mortality trends from United Nations data and six national household surveys between 1998 and 2021 and assessed coverage and inequalities of maternal and newborn health indicators. Quality of care was evaluated from health facility surveys in 2015 and 2019 and emergency obstetric assessments in 2011 and 2017. We determined the impact of intervention coverage on maternal and neonatal lives saved between 2000 and 2020. We interviewed 31 key informants to understand the factors underpinning policy implementation. RESULTS: Empirical maternal mortality ratio declined from 709 to 520 per 100 000 live births during 2000-2011, while neonatal mortality rate declined from 46 to 23 per 1000 live births during 2000-2012 then increased to 43 in 2018. Inequalities in neonatal mortality were reduced across socioeconomic and demographic strata. Key maternal and newborn health indicators improved over 2000-2012, except for caesarean sections, although the overall levels were low. Interventions delivered during childbirth saved most maternal and newborn lives. Progress came from health centre expansion, emergency care and the 2006 fee exemptions policy. During the past decade, challenges included expansion of emergency care, continued high fertility, security issues, financing and health workforce. Social determinants saw minimal change. CONCLUSIONS: Niger reduced maternal and neonatal mortality during 2000-2012, but progress has stalled. Further reductions require strategies targeting comprehensive care, referrals, quality of care, fertility reduction, social determinants and improved security nationwide.

Effectiveness and Cost-Effectiveness of Prophylactic Voriconazole and Fluconazole Regarding Prevention of Post-hematopoietic Stem Cell Transplantation Invasive Fungal Infection and Its Related Death: A Single Center Experience.

PURPOSE: Analyzing effectiveness and cost-effectiveness of voriconazole versus fluconazole prophylaxis in hematopoietic stem cell transplantation (HSCT). METHODS: The research included 70 patients; 34 undergoing allogeneic HSCT and 36 undergoing autologous stem cell transplantation (ASCT), alternated to receive either voriconazole or fluconazole prophylaxis for 180 days on a 1:1 basis. Patients were monitored for occurrence of invasive fungal infections (IFI), IFI-related death (IRD) and total death events. Cost-effectiveness of both agents in both groups was also assessed. RESULTS: Antifungal prophylactic drug had no impact on incidence of IFI and IRD in both allogeneic HSCT and ASCT (P = .452 and P = 1.000; P = .457 and P = .146 respectively). An insignificant difference occurred among patients receiving voriconazole or fluconazole regarding overall survival (OS) and fungal infection-free survival (FFS) in both groups (P = .705 and P = .879; P = .713 and P = .681 respectively). Regarding cost-effectiveness, voriconazole dominated fluconazole regarding prevention of IFI and IRD but was less costly/less effective regarding prevention of total death events and gaining life years in the allogeneic HSCT setting. In the ASCT setting, voriconazole was not cost-effective regarding avoidance of IFI and IRD and was dominated by fluconazole regarding avoidance of total death events and gaining life years. CONCLUSIONS: Voriconazole does not differ from fluconazole regarding its efficacy in prevention of IFI and IRD and does not improve OS and FFS in both allogeneic HSCT and ASCT settings. Voriconazole is cost-effective regarding protection from IFI and IRD in allogeneic HSCT but not cost-effective in ASCT.

Phytoremediation of samples extracted from wastewater treatment plant and their socioeconomic impact.

The physico-chemical and bacteriological quality was evaluated in wastewater samples before and after treatment by microalgae enrichment. Three types of wastewater samples - raw water, inlet water and outlet water - were taken directly from the wastewater treatment plant and subjected to microalgae enrichment culture during two months. The main objective of this work was to apply a phytoremediation process based on the use of compulsory microalgae treatment of wastewater from treatment plants compared to other secondary treatments. The biomass of microalgae was extracted to determine the concentrations of phenolic compounds, sugars and especially lipids, which can be subsequently transformed into biodiesel. As a result, the pH showed a significant increase after microalgae proliferation, with values ranging from 9.94 to 10.36. Bacterial community analysis before and after microalgae culture showed a clear shift in biomass content. The total coliform (TC) and the fecal coliform (FC) contents decreased after microalgae enrichment. In addition, the fecal streptococci (FS) and Pseudomonas present in the different wastewater samples completely disappeared after treatment. The applied phytoremediation process showed a drop until the disappearance of the contagious microbes - which present a very serious health risk - due to the release of the quinic acid. The quinic acid observed in the treated waters exceeded the content of 464.328 mg/L. This phenolic compound naturally produced during the process demonstrated a very effective antimicrobial power. However, a significant increment of 100% of phenol compound removal was observed after microalgae enrichment. The lipid content in the various studied samples appeared after microalgae culture. In addition, the heavy metals, namely cadmium and chromium, were completely eliminated after the treatment. Several socioeconomic advantages can be achieved by the use of this process, notably the environmental advantages of bioenergetics and economic and social benefits of the non-expensive valorization of wastewaters for irrigation.

Effect of immediate postoperative portable radiographs on reoperation in primary total knee arthroplasty.

Cost-containment strategies are of increasing importance in total knee arthroplasty (TKA). Obtaining immediate postoperative radiographs following primary TKA is common practice, but their usefulness is controversial. The goal of this study was to evaluate the effect of immediate postoperative radiographs on reoperation within 60 days, assess film quality, and determine the cost associated with these radiographs. Using a billing registry at the authors' institution, the number of TKAs performed from 2000 to 2011 was determined. Of those, the authors determined which had undergone reoperation within 60 days. They evaluated those who had immediate postoperative radiographs following their primary TKA, and determined those who had been reoperated on as a result of information obtained from these radiographs. Of 6603 patients who underwent primary TKA from 2000 to 2011, 136 (2%) underwent reoperation within the first 60 days. The causes leading to reoperation were arthrofibrosis, infection, wound-healing complications, and hematoma. Of the 136 who underwent reoperation, 76 had immediate postoperative radiographs. None of them underwent reoperation as a result of findings noted in the radiographs. Of the radiographs reviewed, only 43% were deemed adequate by predetermined criteria. The results of the current study demonstrate that these radiographs do not affect the decision for reoperations that occur within 60 days of the index procedure. Although there may be a benefit to immediate postoperative radiographs in selected clinical situations, the decision for routine use needs to be weighed in light of significant cost and limited clinical usefulness.

The physician workforce in Kuwait to the year 2020.

The study addresses the supply of and demand for physicians in Kuwait in the light of the emerging variables such as increasing population, economic growth, changes in healthcare strategies, and expansion of healthcare facilities. The objective of the study was to project the future demand for physicians in Kuwait for the years 2007-2020 based on the period 1994-2006. Population projections were derived using the average annual natural increase rate of the 1994-2006 populations. The future demand for physicians was predicted using the average physician to population ratio for the years 1994-2006. The average annual growth rate of indigenous physicians during the period 1994-2006 was 4.08% compared to 2.83% for non-native expatriot physicians. There is a gap between the numbers of native and foreign physicians. In 2006, native physicians constituted 36.6% of the physician workforce in Kuwait. The disparity between the total number of physicians needed and the number of native physicians is expected to decline from 62.14% in 2007 to 48.1% in 2020. The supply of indigenous physicians should be increased. Without shared culture and language, it will be difficult to provide effective and efficient medical care to the people of Kuwait. This can be achieved through an improvement in recruitment and retention of indigenous physicians and medical students. There is also a need for establishment of a standing advisory committee for continuous monitoring of physician workforce planning and policy strategies in Kuwait.

Stem cell transplantation in hematological disorders. A developing country experience-impact of cost considerations.

OBJECTIVE: To describe the experience in setting up a bone marrow transplant program at Ain Shams University, Cairo, Egypt. METHODS: Sixteen patients were transplanted at Ain Shams University Bone Marrow Transplantation unit from March 2005 to January 2008. RESULTS: Sixteen patients were transplanted with a median age of 25 years. Indications for transplantation were chronic myeloid leukemia, acute myeloid leukemia, aplastic anemia, acute lymphoblastic leukemia, and aggressive lymphoma. Seven donors and 6 patients were positive for cytomegalovirus immunoglobulin G (IgG) antibody (Ab) pretransplant. Only one patient was positive for toxoplasma IgG Ab and another had a high titre for toxoplasma IgM Ab pretransplant. Two donors and 2 recipients were positive for hepatitis B antibody markers; however, none were positive for hepatitis B virus DNA by polymerase chain reaction (PCR). None of the patients or donors were positive for hepatitis C virus via PCR pre-transplant. Acute graft versus host disease (GVHD) was seen in 3 patients, while chronic GVHD was seen in 5 patients. Primary cause of death was recurrence in 2 patients and graft failure in one patient. Thirteen are alive and disease free with a median follow-up of 20 months. CONCLUSION: Although our unit is a relatively new unit, these results are comparable to those achieved in the Western world and cost a mean of US$250,000.

Dental patient awareness of smoking effects on oral health: Comparison of smokers and non-smokers.

OBJECTIVES: The negative effects of cigarette smoking on oral health are well established, yet few studies assessed patient awareness of such effects. The aim of this study was to examine differences in dental patient knowledge and awareness of the effects of smoking on oral health between smokers and non-smokers. METHODS: Adult patients from 12 dental centers in Kuwait were asked to complete a 14-point self-administered structured questionnaire on the effects of smoking on oral health in this cross-sectional survey. Significant associations between oral health knowledge, smoking status, and sociodemographic variables were examined with univariate analysis and logistic regression. RESULTS: A total of 1012 subjects participated (response rate = 84.3%). The prevalence of smoking was 29.3%. Fewer smokers than non-smokers thought that oral health and smoking are related (92.2% vs. 95.8%; P = 0.020), and that smoking affected oral cancer (52.4% vs. 66.8%; P < 0.001), periodontal health (72% vs. 78%; P = 0.040), or tooth staining (86.1% vs. 90.9%; P = 0.018). Logistic regression analysis showed smokers to be significantly less aware of the oral health effects of smoking than non-smoking patients (OR=1.51; 95% CI: 1.05-2.16; P = 0.025). CONCLUSION: Smoking dental patients are significantly less aware of the oral health effects of smoking than non-smokers. Comparative studies in other populations may be warranted to ascertain the validity of these results.

Assessment of parathyroid autotransplantation for preservation of parathyroid function after total thyroidectomy.

BACKGROUND: Hypoparathyroidism with permanent hypocalcemia is a well-recognized complication after thyroid surgery. AIM: This study was conducted to assess the role of immediate parathyroid autotransplantation in the preservation of parathyroid function after total thyroidectomy. PATIENTS AND METHODS: Twenty-eight patients had autotransplantation of parathyroid glands resected or devascularized during total thyroidectomy. Data were collected prospectively regarding demographics, indication for surgery, operative procedure, pathologic diagnosis, number of glands transplanted, and subsequent course. Thyroid nodules were evaluated by ultrasonography, radionuclide scanning, and/or fine-needle aspiration cytology. All patients had serum ionized calcium, phosphorus, and intact parathyroid hormone (PTH) levels measured preoperatively and monitored regularly postoperatively for a period of 14 weeks and again at 6 months after operation. Patients were categorized into three groups according to the number of glands transplanted: one (group 1, n = 6), two (group 2, n = 14), or three glands (group 3, n = 8). In three other volunteers, one parathyroid gland was transplanted in the brachioradialis and subjected to electron microscopy 1, 2, and 4 weeks after transplantation. RESULTS: Total thyroidectomy was performed for malignant disease in 16 patients (57.1%) and for benign disease in 12 (42.9%) patients. All patients reverted to asymptomatic normocalcemia without the need for any medications within 4 to 14 weeks. Normal levels of serum markers were regained slower when one gland was transplanted compared with two or three glands (P <.01). Electron microscopic examination showed evidence of ischemic degeneration in the transplanted tissues 1 week postoperatively. Regeneration started by the second week and coincided with normalization of PTH levels. Optimum resting and nearly normal status of parathyroid tissue was achieved by the fourth week. CONCLUSIONS: This study showed that active PTH production coincides with regeneration of parathyroid cells and that autotransplantation of at least two resected or devascularized glands during total thyroidectomy nearly eliminates permanent postoperative hypoparathyroidism, thus improving the safety of total thyroidectomy performed for malignant or benign disease.

Patient satisfaction with three dental speciality services: a centre-based study.

OBJECTIVE: To assess the level of patient satisfaction with three dental speciality services: oral surgery, periodontics, and fixed prosthodontics. SUBJECTS AND METHODS: A sample of 1,242 patients, aged 16 years and over who received dental care at least twice at the main dental centre, Al-Amiri, Kuwait, were interviewed during May-August 1998 by independent researchers concerning their experience of previous visits. Patients reported their level of satisfaction on a 5-point Likert scale for the items in the questionnaire, which focused on four areas: access, dentist's communication, staff helpfulness, and structural aspects of the practice. RESULTS: On average 49.4% (25.9-89.6%) of participating patients rated the level of care received as excellent. Areas rated poorest included waiting time for an appointment and waiting time in the clinic to access the dentist. Participants were less satisfied with doctor's explanation of illness, dental treatment and confidentiality of medical records. The areas that received excellent ratings by patients included: (a) communication (listening and understanding complaints 40.0% and courteous treatment 57.8%), and (b) structural aspects (availability of infection control and safety measures 89.6% and packed sterilized instruments 78.9%). CONCLUSION: Findings indicate that the level of patient satisfaction was reasonably high. Areas identified as needing improvement included: dentist-patient communication skills, medical records, appointment systems, and shortening of the waiting time to access the dentist.
