Plant communities play an important role in the C-sink function of peatlands. However,global change and local perturbations are expected to modify peatland plant communities,leading to a shift from sphagnum mosses to vascular plants. Most studies have focused on the direct effects of modification in plant communities or of global change(such as climate warming, N fertilization) in peatlands without considering interactions between these disturbances that may alter peatlands' C function. We set up a mesocosm experiment to investigate how Greenhouse Gas(CO_2, CH_4, N_2O) fluxes, and dissolved organic carbon(DOC)and total dissolved N(TN) contents are affected by a shift from sphagnum mosses to Molinia caerulea dominated peatlands combined with N fertilization. Increasing N deposition did not alter the C fluxes(CO_2 exchanges, CH_4 emissions) or DOC content. The lack of N effect on the C cycle seems due to the capacity of sphagnum to efficiently immobilize N. Nevertheless, N supply increased the N_2O emissions, which were also controlled by the plant communities with the presence of Molinia caerulea reducing N_2O emissions in the sphagnum mesocosms. Our study highlights the role of the vegetation composition on the C and N fluxes in peatlands and their responses to the N deposition. Future research should now consider the climate change in interaction to plants community modifications due to their controls of peatland sensitivity to environmental conditions.

Open Journal of Radiology 2023年第2期13卷 87-93页

Eclampsia is a common complication of hypertensive disorders of pregnancy and in the puerperium with the attendant risk to both the mother and baby. Although it is a multi-systemic disorder, its manifestation that affects the brain and resulting in altered sensorium demands brain imaging to define the possible brain lesions and the implications for critical care management and outcome. We evaluated the CT brain lesions in the patients with eclampsia who were admitted in the intensive care unit, University of Port Harcourt, Port Harcourt Nigeria. Objective: To analyse the CT brain images of eclamptic parturients and the outcome following their admission in the intensive care unit. Methods: We undertook this observational study after obtaining ethical exemption from the University of Portharcourt Teaching Hospital ethical review board, and commenced the review between March 2021 to February 2023. We included all parturients that were admitted into the intensive care unit of the University of Portharcourt Teaching Hospital, a nine-bedded open intensive care unit with the clinical diagnosis of eclampsia. Every admitted parturient was required to obtain a brain computed tomography (CT) by local protocol. The brain CT images were retrieved for review from the parturients’ relatives, radiology department and the ICU. Parturients included were aged ≥ 18 years. The radiological reports of these brain images which were also reviewed by a neurosurgeon in case of any need for secondary opinion were subjected to statistical analysis. Result: Thirty-one parturients were admitted with eclampsia with a mean age of 30 years ± 5.29. sixteen (16) parturients died representing 52%. Only twenty-four (24) CT brain images were retrieved for review (77%). The following brain lesions were identified from the brain CT and they comprised the following: intracerebral haemorrhage, including extensions into the ventricles 7 (29.17%), cerebral oedema 12 (50%), subdural hematoma 1 (4.17%) and norm

A 365-Day Record of Maternal Admissions in Intensive Care Unit at the University of Port Harcourt Teaching Hospital in Nigeria

引用

Journal of Biosciences and Medicines 2023年第4期11卷 296-303页

作者： Job gogo Otokwala Osita Celestin John Intensive Care Unit Department of Anaesthesiology Faculty of Clinical Sciences University of Port Harcourt Port Harcourt Nigeria Department of Obstetrics and Gynaecology Faculty of Clinical Sciences University of Port Harcourt Port Harcourt Nigeria

BACKGROUND. The intensive care unit provides critically ill patients with the necessary monitoring, care and supports to optimize their organ/system functions. Parturients are often at risk of sudden deteriorations or exacerbation of chronic illnesses from direct or indirect causes and would often require admissions into the intensive care or high dependency unit. This study is aimed at looking at the trends of maternal admissions in 365 days at the intensive care unit of a tertiary teaching hospital in southern part of Nigeria, a country that contributes significantly to the global proportion of maternal morbidity and mortality. METHODs. The study adopted a retrospective approach. All critically ill parturients admitted and requiring organ support or close monitoring in the ICU had their files and ICU documents reviewed. The review was held from January-December 2018. REsULTs. Thirty-nine (39) parturients with a mean age (years) of 33 ± 1.3 were admitted, representing 2.9% of annual deliveries. All admissions were postnatal and came predominantly from the unbooked labour ward (51%) and the time lag from maternal deteriorations to presentation to the ICU was 72 ± 10 hours. The main indications for admissions were due to postpartum haemorrhage (33.3%), complications of hypertensive disorders of pregnancy (30.9%) and sepsis (25.6%). Nineteen (48.7%) patients died from obstetric haemorrhage, complications of hypertensive disorders of pregnancy, sepsis and pulmonary embolism. CONCLUsION. The trend of maternal admissions at this specific time frame reflects the burden of maternal critical care in our environment. It highlights the need to holistically tackle the known scourge with improved care.

Reawakened sexual Interest: The Result of surgical Correction of Concealed Penis

surgical science 2023年第4期14卷 295-302页

作者： Mishack Ikechukwu Akunekwe Blessing Etukakpan Job gogo Otokwala Plastic & Reconstructive surgery Unit Department of Surgery Federal Medical Centre Yenagoa Nigeria Department of surgery Federal Medical Centre Yenagoa Nigeria Department of Anaesthesiology University of Port Harcourt/University of Port Harcourt Teaching Hospital Port Harcourt Nigeria

Concealed penis (CP) is a developmental anomaly in which the penis is hidden in the skin of the abdomen, thigh or scrotum. As a result of this, the penis appears shortened in length. It was first described by Keyes Jr. E.L. in 1919. It can be associated with voiding problem and in adults, sexual issues, among others. Objective: To show that surgery can reverse celibacy induced by CP and highlight the need for an interdisciplinary approach to correction of this anomaly. Patient and Method: A thirty-one-year male patient who had a surgical release of his buried penis by two surgeons in 2019 in a private hospital. The case note was reviewed, the data obtained analyzed and the results including photographs, were presented. The patient was followed up. Result: A 10 cm length of penis and a hundred percent (100%) take of sheet of split skin graft used to resurface the denuded penis were achieved using combined spinal and epidural anesthesia. The patient, his mother and the surgeons were satisfied with the outcome. Consequently, he resolved to marry a wife after all. Conclusion: Concealed penis can now be regarded as a known cause of celibacy and surgical correction can reverse the celibate state.

本文的研究旨在确定象牙海岸农产品出口对当地经济增长的比重。论文分析中以可可为例,分析农产品出口与经济增长之间的关系。由于科特迪瓦是世界上第一大可可生产国,其产量占世界的40%,因此,分析可可生产在经济增长中的重要性非常重要。论文研究中数据取主要来自世界银行,以及1990年至2016年的粮食农业组织提供的统计数据。包括国内生产总值,可可豆,劳动力,国内固定资本总值,消费者价格指数。研究方法使用协整模型、纠错模型和格兰杰因果关系模型进行分析。本研究共分为六章,研究中得出的结论有:可可豆出口对经济增长具有负面影响或非显著性影响,也就是说可可出口对象牙海岸的经济增长没有负面影响;另外,研究还得出劳动力对经济增长的影响也是非显性因素。同时,根据论文的发现,建议应实施旨在提高这种作物的生产力和质量的政策,而这种提高的唯一的方法是通过提高单位产品的价格来获得丰厚的报酬。另外,在出口之前,应在可可豆中增加附加值,这样才能达到促进经济增长的期望。但是,对于那些从事可可豆生产的农民,为了确保他们能够从生产中获利或保证他们的最低利益,政府必须探索在可可豆出售前在农民家中进行可可豆加工的可能性。这样才能保证农民的基本利润,这样,农产品出口对该国的经济增长具有显著性。
