Abstract:
Malaria is a complex parasitic disease affecting about 32 million pregnancies each year in sub-Saharan Africa. Pregnant women are especially susceptible to malarial infection and have the risk of developing severe disease and birth complications. The target of Millennium Development Goal 6 is to end malaria deaths by 2015. Maternal and perinatal morbidity and mortality due to malaria may be reduced by implementing preventive measures, early diagnosis of suspected cases, effective antimalarial therapy and treatment of complications.

Abstract:
Introduction: Complications of malaria can develop suddenly and unexpectedly. Although various parameters have been associated with severity of malaria, they have not been studied as predictors of these events. Many of the malarial complications are inflammatory in nature, and C-reactive protein (CRP) and elevated erythrocyte sedimentation rate (ESR) could be early markers of these complications and might precede and predict the development of complications. Methodology: A total of 122 inpatients with uncomplicated newly diagnosed malaria were studied. CRP, ESR, hemoglobin, and platelets were measured before initiating treatment. Patients were monitored closely for the subsequent development of complications based on the World Health Organization’s definition of severe malaria. Results: Seven patients (5.7%) had worsening of symptoms compared to the day of admission and had higher pretreatment CRP and increased ESR compared to those patients who did not develop complications. Area under receiver operator characteristic curve was 0.761(p=0.02) for CRP and 0.739 (p = 0.035) for ESR. CRP>124 mg/L and increased ESR (>34.5 mm in the first hour) had a sensitivity of 71.4% and specificity of 79.1%, respectively, for predicting complications of malaria. Other parameters did not reach statistical significance for predicting complications. Elevated CRP and elevated ESR had a negative predictive value of 97.8%. Conclusions: Elevated CRP>124mg/L and increased ESR>34.5 mm in the first hour at the time of diagnosis in patients with uncomplicated malaria identifies patients who might subsequently develop complications of malaria.

Abstract:
The study visualizes the Prevention of Malaria among Pregnant Women Attending Antenatal Clinic. Malaria in pregnancy has been identified as a global health challenge because of the life-threatening complications it poses to both the mother and the unborn child. These complications include maternal anemia, premature delivery, low birth weight, miscarriage, congenital infection and perinatal mortality. Five different malaria parasite species cause malaria infection: Plasmodium falciparum, Plasmodium vivax, Plasmodium malariae, Plasmodium ovale and Plasmodium knowlesi. The increasing rate of malaria among pregnant women and the lack of adherence to malaria preventive measures have become a matter of great concern for health authorities and midwives. Different factors have been thought of as reasons for the increasing malaria rates. The study review malaria, malaria prevention and control during pregnancy, knowledge of pregnant women on risk factors of malaria, and the attitude of women about the risks of malaria during pregnancy. However, the study recommended that Health training institutions update their curriculum, considering the need for more education on malaria and its prevention policymakers.

Abstract:
Background Severe malaria causes multi-organ involvement ,including hepatic dysfunction.Jaundice in severe malaria is foundmore commonly in adults than in children. It is important toassess the factors associated with malarial hepatopathy, the variedclinical presentations, as well as the complications in order toinitiate early interventional measures. There are a limited numberof studies in the pediatric population on malarial hepatopathy.Objective To assess the factors associated with malarialhepatopathy, the varied clinical presentations, as well as itscomplications.Methods This prospective study was conducted in the Departmentof Paediatrics, Sardar Vallabh Bhai Patel Post Graduate Institute ofPaediatrics (SVPPGIP), Cuttack, Odisha, India from January 20 10to June 2013, and included 70 children with malaria and jaundice,aged 6 months to 14 years. Malaria was confirmed by microscopicexamination of blood smears. Detailed clinical evaluations andinvestigation s were carried out to find multi-organ afflictions,with a special emphasis on hepatic involvement.Results Of218 children with malaria admitted during this period,70 (32%) children had fever and jaundice on presentation. Allchildren who had both Plasmodium faldparum and vivax infectionhad malarial hepatopathy. Complications, including acutekidney injury (AKI), disseminated intravascular coagulation(DIC), cerebral malaria, and mortality, were significantlyhigher among children with malarial hepatopathy compared tochildren without hepatopathy. Howevei; there was no significantdifference of hypoglycemia, respiratory distress syndrome (RDS),convulsions or severe anemia, between children with and withouthepatopathy.Conclusion Hepatopathy is more common with mixed malariainfections. The incidence of AKI, DIC, cerebral malaria, andmortality are significantly higher in patients with hepatopathy.Malarial hepatopathy should be considered in patients presentingwith acute febrile illness and jaundice so that specific treatmentcan be initiated early to prevent increased morbidity and mortality.

Abstract:
Background. Thrombocytopenia is a most commonly observed complication during malaria infections. Inflammatory cytokines such as IL-1, IL-6, and IL-10 have been documented in malaria induced thrombocytopaenia. This study was aimed to understand the possible relationship between inflammatory cytokines across varying degrees of thrombocytopenia during P. vivax, P. falciparum, and mixed infections. Methods. A hospital-based cross sectional study was conducted at District Wenlock Hospital in Mangaluru, a city situated along the south-western coastal region of Arabian Sea in India. In this study, blood samples from 627 malaria patients were analyzed for infected parasite species, clinical conditions, platelet levels, and key cytokines that are produced in response to infection; samples from 176 uninfected healthy individuals were used as controls. Results. The results of our study showed a high prevalence of malarial thrombocytopenia (platelets <150 ×103/μl) in this endemic settings. About 62.7% patients had mild-to-moderate levels of thrombocytopenia and 16% patients had severe thrombocytopenia (platelets <50 × 103/μl). Upon comparison of cytokines across varying degrees of thrombocytopenia, irrespective of infecting species, the levels of TNF-α and IL-10 were significantly higher during thrombocytopenia, whereas IL-6 levels were considerably lower in severe thrombocytopenia patients suffering from P. vivax or P. falciparum infections. The severe clinical complications observed in patients with malarial thrombocytopenia included severe anemia (17.5%), acute renal failure (12.7%), jaundice (27.0%), metabolic acidosis (36.5%), spontaneous bleeding (3.2%), hypoglycemia (25.4%), hyperparasitemia (4.8%), acute respiratory distress syndrome (1.6%), pulmonary edema (19.0%), and cerebral malaria (1.6%) in various combinations. Conclusion. Overall, the results of our study suggest that inflammatory cytokines influence the transformation of mild forms of thrombocytopenia into severe forms during malarial infections. Further studies are needed to understand the association of inflammatory cytokine responses with severe malaria complications and thrombocytopenia.

Abstract:
Severe anemia is a major life-threatening complication of malaria. Inappropriately low reticulocytosis in malaria patients with anemia suggests insufficient erythropoiesis, of which the mechanisms and implications are not clear. The principle growth factor that promotes erythropoiesis is erythropoietin (Epo). Studies determining the serum level of Epo in malaria infected patients have been inconclusive. Furthermore, the role of Epo and the erythropoietic response to Epo stimulation during malaria have never been examined. The purpose of the experiments performed in this thesis was, thus, to investigate the role of Epo and erythropoiesis in relation to anemia during blood-stage malaria using the murine model of Plasmodium chabaudi AS. A murine Epo specific ELISA, which was determined to be less biased by the presence of other cytokines in the samples as compared to the conventional Epo bioassay, was first developed to facilitate the research. The kinetics of Epo production in the kidney and the levels in the serum were characterized. It was demonstrated that Epo production during blood-stage malaria is mainly regulated by the degree of anemia and that renal cytokines may have only a minor effect on this response. Next, the roles of Epo and erythropoiesis during blood-stage malaria were investigated by neutralization of endogenous Epo or by administration of exogenous Epo. Timely onset of Epo-induced reticulocytosis was shown to be important for the alleviation of malarial anemia and survival. However, reticulocytosis in response to Epo stimulation is severely suppressed by infection with malaria. Dissection of the upstream events of erythropoiesis demonstrated that blood-stage malaria compromises the generation of reticulocytes by suppressing the proliferation, differentiation, and maturation of erythroid-lineage cells at various stages of erythroid development. Taken together, our data provide important insights for understanding the patho

Abstract:
Cerebral malaria is a common encephalopathy in African children, but the cause of death and neurological sequelae are unknown. This dissertation examines the hypothesis that raised intracranial pressure (ICP) is a determinant of poor outcome in Kenyan children with cerebral malaria. The opening cerebrospinal fluid pressure was raised in all 26 children in whom it was measured on admission and 92% of 35 children in whom it was measured after admission. Brain stem signs, particularly an abnormal respiratory pattern, absent pupillary responses and a lack of spontaneous eye movement were associated with a death. In 33 children who died with cerebral malaria, at least 18-42% had clinical features of transtentorial herniation, according to the criteria used. Intracranial pressure monitoring was performed in 18 children with severe CM, of whom 14 had computerised tomography (CT) and in 10 the basal cranial arteries were monitored with transcranial Doppler (TCD) sonography. Three children with severe intracranial hypertension (maximum ICP > 60 mmHg and minimum cerebral perfusion pressure (CPP) < 40 mmHg) had a poor outcome despite aggressive therapy with mannitol. One child with a maximum ICP of 151 mmHg died with the signs of uncal and medullary stages of herniation. In the other 2 children, middle cerebral artery velocity and vascular resistance monitored with TCD sonography changed with ICP and CPP. Both of these children had diffuse brain swelling associated with generalised hypodensity on their acute CT scans. These children survived° with cerebral atrophy on their convalescent scans and severe neurological deficits. In the 8 children with intermediate intracranial hypertension (maximum ICP 20-60 mmHg and CPP < 50 mmHg) mannitol was effective in controlling the intracranial hypertension. TCD was not reliable in detecting changes in ICP or CPP. Two of these children had acute brain swelling, but the tomographic density was normal and the swelling had resolved when the repeat scans were performed 12-24 days later. All the children with intermediate intracranial hypertension survived without major neurological sequelae. In the remaining 7 children who had ICP monitoring, the maximum ICP was <20 mmHg and mannitol was not administered. None of the CT scans showed brain swelling and the children survived without severe sequelae. In a further 9 children with severe malaria (6 with CM) the agonal stages were monitored with TCD. Three children with CM had sonographic features of progressive intracranial hypertension associated with signs of herniation, whilst the other children (including 3 with CM) did not have these sonographic features, although one had evidence of brainstem compromise before dying. Thus raised ICP is a feature of CM in Kenyan children. Severe intracranial hypertension is associated with a poor outcome and could be responsible for at least a third of the children dying from CM. Mannitol reduces the ICP, but does not prevent nor control severe intracranial hypertension.

Abstract:
Seulement 1 à 3% des cas de paludisme dégénèrent en NP. Cependant, les séquelles à long termes touchent 3 à 10% des adultes et 25% des enfants et ces personnes présentent des déficits cognitifs notamment au niveau de l'apprentissage. Au niveau de l'armée française, ce sont 15 000 militaires qui sont exposés chaque année dans les zones impaludées, avec au moins 350 accès palustres mais surtout 1 à 2 morts chaque année.Dans le but de lutter contre P. falciparum mais aussi diminuer les séquelles dans le cas du NP deux molécules ont été étudiées. D'une part, l'atorvastatine (AVA) et d'autre part le bleu de méthylène (BM). Les données, précédemment publiées, ont montré l'efficacité de l'AVA non seulement comme antibactérien, antiviral ou antiparasitique mais aussi comme modulateur de l'immunité et adjuvant potentiel pour les antipaludiques actuels. Le BM est un antipaludique qui jusqu'ici présentait une voie de synthèse avec métaux lourds. C'est une nouvelle voie de synthèse sans métaux lourds et une efficacité démontrée qui nous ont incités à étudier cette molécule.Pour estimer l'efficacité de l'AVA et du BM en association avec les antipaludiques actuels nous avons successivement testé ces molécules dans un modèle in vitro (micro test isotopique simplifié) contre P. falciparum, puis dans un modèle murin de neuropaludisme en utilisant des souris C57BL/6N infectées avec Plasmodium berghei. Un gain d'efficacité a été observé en associant l'AVA ou le BM avec les antipaludiques contre P. falciparum mais aussi une protection par rapport au NP chez les souris traitées par les associations. Le BM protégeant aussi bien contre le paludisme simple que le NP
Only 1 to 3% of malaria infections turn into CM. Meanwhile, long term neurological sequelae range from 3 to 10 % in adults and 25% of child survivors present long term cognitive impairments. In a military framework, there are 15 000 soldiers localized in endemic malaria areas, with at less 350 infection cases giving clinical malaria syndrome but mainly 2 deaths each year.In the aim to fight against P. falciparum but also to decrease sequelae related to CM, two molecules were studied. In one hand, atorvastatin (AVA) and in the other hand methylene blue (MB). AVA is a synthetic inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A (3HMG-CoA) reductase used in the treatment of hypercholesterolemia. Previous data, reported in numerous articles support the efficacy of AVA not only as antimicrobial, antiviral or antiparasitic agent but also as immune system modulator and potential adjuvant in vitro for common antimalarial drugs. BM is an antimalarial drug which until now had a synthesis pathway with heavy metals. It is a new synthesis pathway without heavy metals and an efficacy demonstrated which encouraged us to study this molecule.To evaluate AVA and BM efficacies in combination with common antimalarial drugs, we successively tested these molecules in an in vitro model (simplified isotopic microtest) against P. falciparum, then in experimental cerebral malaria using C57BL/6N mice infected with Plasmodium berghei. An increased efficacy was observed when AVA or MB is associated with common antimalarial drugs against P. falciparum but also a protection against CM in mice treated by drugs combinations. MB protects against malaria but also CM

Abstract:
Malaria is a subtropical and tropical protozoan infection that accounts for nearly half a million deaths each year. Most deaths occur in sub-Saharan Africa and are caused by Plasmodium falciparum. The least studied of the five Plasmodia species that cause malaria, P. knowlesi, along with P. vivax cause life-threatening disease, mostly in Southeast Asia. Children, pregnant women, and non-immune travellers to endemic countries are most vulnerable to severe malaria. Cerebral malaria and anaemia are complications that results in neurological deficit and death if treatment is delayed or inappropriately administered. Rapid diagnostic tests have emerged as accurate and reliable means to diagnosing malaria at point-of-care.

Abstract:
Background: Gestational diabetes mellitus (GDM) is a major public health problem because of its associated complications during pregnancy. Studies have suggested that women with positive parental history of diabetes may be predisposed to an increased GDM risk. This study aimed to examine the correlation between family history with diabetes mellitus and the gestational diabetes mellitus. Subjects and Method: This was a meta-analysis and systematic review. The study was collected articles from PubMed, Science Direct, and Google Scholar databases, from year 2017 to 2020.

Abstract:
Abstract In order to extract the remaining reserves from a depleted carbonate field as well as to explore the possibility of finding additional reserves in a new fault block, PETRONAS is required to drill an Extended Reach Drilling (ERD) well from the existing platform in the FX field. The new target block is located approximately 4 km from the existing platform. This paper summarizes the planning challenges as well as the solutions in delivering the ERD well in a carbonate reservoir. During the design phase, the team put a high emphasis in avoiding any complications while drilling an ERD well in a carbonate reservoir especially in managing severe or total losses. As such, the subsurface team came out with a novel approach in mapping the karst in the carbonate reservoir allowing optimum placement of the well trajectory. With the optimized target, the well was designed accordingly, addressing all the challenges that were raised during the detailed risk assessment such as hole cleaning issues, wellbore instability, Equivalent Circulating Density (ECD) management, Torque and Drag (T&D) during drilling as well as running casings/liner, cement integrity in high angle well etc. An ERD consultant was engaged to facilitate the design and execution phases. The final well design and implementation plans were finalized with the ERD consultant's assistance which addressed all the anticipated challenges. An Advanced 1D Mechanical Earth Model (MEM) was constructed with the latest offset data to determine the proper mud weight window to drill the ERD well. The finalized Torque and Drag simulation provided the necessary strategies in completing the well including expected drilling parameters as well as delivering the casing and liner to bottom. Ensuring cement integrity while managing ECD by implementing new technology was also planned. The new technologies and specific approaches implemented to deliver the ERD well in a carbonate reservoir include detailed Seismic analysis to detect and predict the presence of karst in the carbonate, Pseudo Catenary well trajectory to optimize the well trajectory, 9-5/8" liner full air flotation to get the liner to bottom, Definitive Survey While Drilling to reduce vertical uncertainties as well as minimizing the stationary time and flow diverter to ensure cement integrity especially in the high angle / horizontal sections.

Abstract:
Abstract Sand production remains as one of the most challenging complications in managing mature fields in Malaysia. More than half of the wells in Malaysian fields are completed with downhole primary sand control or require sand management throughout their lifetime. To further aggravate the issue, most primary sand controls installed have suffered from failure after an extended period of production. Thus, operators are often compelled to rely on thru-tubing metallic sand screens to reactivate idle sand wells. However, most metallic sand screens suffer from sustainability issue due to substantial erosion especially for those installed in wells with high gas flow rate. Therefore, alternative technology such as through-tubing ceramic sand screen (TTCSS) has been considered and applied due to its higher durability and resistance against erosion. This paper will discuss the evolution of TTCSS design and performance improvement in terms of longevity. Field application in Malaysian mature fields has shown that ceramic sand screen demonstrates a longer lifetime when compared to conventional metallic sand screen. However, to further improve the mean time between failures (MTBF) of TTCSS, extensive studies have been conducted by carrying out detailed teardown investigation and computational fluid dynamic (CFD) simulation. Design changes have been proposed and incorporated to mitigate the erosion risk at end cap area based on previous well installation. The enhanced TTCSS were then installed in the same well with high erosional velocity as pilot testing. The operating well envelope and installation method were maintained following the previous installation. TTCSS with enhanced design were then retrieved after a period of three months for detailed evaluation. Several criteria have been identified as key performance indicators for the success of enhanced TTCSS design. Throughout the pilot testing period, sand production at surface has been closely monitored to detect any sand grains larger than screen slot sizing. Upon retrieval, enhanced design of TTCSS shall not exhibit similar erosion patterns at end cap area which will affect the integrity of spring compensator system and cause the screen to lose its filtration mechanism. Lastly, enhanced TTCSS design shall prevent parting of screen during retrieval, reducing the risk of leaving the screen downhole as fish. This paper will present the outcome of pilot testing of enhanced TTCSS by comparing the performance with the original design using both teardown investigation and velocity calculation. Suggestion for further optimization will also be discussed to ensure TTCSS remains as one of the competent candidates for remedial sand control which can offer greater durability and longevity.

Abstract:
Abstract PETRONAS Carigali (PCSB) has developed a solution to monetize industry top decile worth reservoir complexity in the deepwater environment via Limbayong field, Malaysia. The field complexity is acknowledged by Independent Project Analysis (IPA) as industry top decile reservoir complexity due to severe elongated structure (30km length, 2.5km width) with varying faults frequency, vertical intercalation of thin-bed, thick sand reservoir and lateral compartmentalization which impend effectiveness of well drainage and pressure maintenance. The four (4) appraisal wells result since 2002 give diverse subsurface understanding, indicated possible different depositional model and greater degree of complication. This paper describes the key development challenges and strategies that significantly improve the field value proposition for FID. PCSB pivoted to focus assessment on low realization case for development. It generated advanced reservoir mapping to simulate sand distribution and concentration through incorporated faults re-interpretation, refined grid resolution, and change of facies prediction, increasing the stratigraphic compartments. The team performed integrated subsurface-surface flow assurance modeling and validated turndown limit for production and operation. Subsequently, iterated concepts for incremental reservoir recoverable by high-grading producer-injector pairing, wells-facilities design provision for a base, upgrade, or future tie-in. The team formulated industry collaboration (IC) studies in each FEL phase with drivers for deepwater technology enablers implementation in EPCIC primarily via concept selection, engineering standardization, and design competition. Each distinct concept is ratified with project economics group value chain evaluation and stakeholders’ alignment. The breakthrough signifies merit in the key strategies and templates to overcome similar-scale project complexity with viable business cases. The IC affirmed cost proposition of 20 to 30% lower than industry average for deepwater wells and facilities, ensuring it to be positioned in top quartile project performance. It re-defined minimum technical design and demonstrated a prominent value trade-off for scaling-up concepts. It drives momentum to monetize high complexity reservoirs even further in the deepwater environment, which otherwise remains undeveloped. There is potential for replication throughout nearly 800MMboe scattered fields within deepwater offshore Sabah, Malaysia. Deepwater offshore has a niche role in bridging global transition between energy mix offering and net-zero economy target. It produces among the industry's smallest carbon footprints yet with high economic efficiency. Consolidated and efficient development strategies accelerate the decarbonization pathway. It advocates a hybrid capital project management model to manage extreme uncertainties with design thinking, lean startup, and agile approach.

Abstract:
Abstract PETRONAS completed Well H16 in BS field, East Malaysia with a Digital Intelligent Artificial Lift (DIAL) – an improvement to the current applied gas lift system in the field for production optimization system. This DIAL installation represents the first ever successful installation of the technology in an Offshore oil well for Dual String production. This paper provides the details of the installation planning, designing stages, operational process, well unloading and production undertaken to achieve this milestone. DIAL is a unique technology that enhances the efficiency of gas lift production. Downhole monitoring of production parameters informs remote surface-controlled adjustment of gas lift valves. This enables automation of production optimization removing the need for well intervention which will be challenging in high deviation well (more than 60-degree deviation). With remotely operated, non-pressure dependent multi-valve units, the technology removes the challenges normally associated with gas-injected production operation in a dual completion well i.e., gas robbing and multi-pointing. DIAL introduces a paradigm shift in design, installation and operation of gas lifted wells. This paper will briefly highlight the justifications of this digital technology in comparison with conventional gas lift techniques. It will consider value added from the design stage, through installation operations, to production optimization. Digitization and automation have become the new concepts in managing the operations in order to boost efficiency that reflected in long-term cost savings especially in Operating Expenditure (OPEX). This paper focusses on a well completed in November 2020, the fourth well to be installed with the DIAL technology across PETRONAS Assets. The authors will provide details of the well strategy, installation process and production phases: system design, pre-job preparations, improvements implementation, run in hole and surface hook-up. The results of well unloading while utilizing the DIAL system to start up the well and lifting the completion brine will be explained in detail in this paper. For each phase, challenges encountered, and lessons learned will be listed together with observed benefits. Despite the additional operational & planning complications due to COVID-19 restrictions, the well was completed with zero Non-Productive Time (NPT) and Loss Time Injury (LTI). Once brought online, this DIAL-assisted production well can be remotely monitored and controlled ensuring continuous production optimization, part of PETRONAS’ upstream digitization strategic vision.
