Abstract
ABSTRACTThis study presents the use of a low-temperature hydrothermal method for extracting calcium sources from green mussel shell (P. Viridis) wastes and converting them into synthetic nanosized hydroxyapatite (HA). In this study, raw mussel shells were washed, pulverised, and sieved to start producing a fine calcium carbonate-rich powder. XRD quantitative analysis confirmed that the powder contains 97.6 wt. % aragonite. This powder was then calcined for 5 h at 900 °C to remove water, salt, and mud, yielding a calcium-rich feedstock with major minerals of calcite (68.7 wt.%), portlandite (24.7 wt.%), and minor aragonite (6.5 wt.%). The calcined powders were dissolved in aqueous stock solutions of HNO3 and NH4OH before hydrothermally reacting with phosphoric acid [(NH4)2HPO4], yielding pure, nanoscale (16-18 nm) carbonated HA crystals, according to XRD, FT-IR, and SEM analyses. The use of a low-temperature hydrothermal method for a feedstock powder produced by the calcination of low-cost mussel shell wastes would be a valuable processing approach for the industry's development of large-scale hydroxyapatite nanoparticle production.

Abstract
OBJECTIVE International guidelines recommend that preterm infants should be supported to maintain their serum electrolytes within "normal" ranges. In term babies, cord blood values differed in pathological pregnancies from healthy ones. STUDY DESIGN We examined cord blood sodium, chloride, potassium, glucose, and creatinine to derive maturity-related reference intervals. We examined associations with gestational age, delivery mode, singleton versus multiple, and prenatal maternal adverse conditions. We compared preterm cord values to term, and to adult reference ranges. RESULTS There were 591 infants, 537 preterm and 54 term. Preterm cord glucose levels were steady (3.7 ± 1.1 mmol/L), while sodium, chloride, and creatinine increased over GA by 0.17, 0.14 mmol/L/week, and 1.07 µmol/L/week, respectively (p < 0.003). Average preterm cord potassium and chloride were higher than the term (p < 0.05). Compared with adult reference intervals, cord preterm reference intervals were higher for chloride (100-111 vs. 98-106 mmol/L), lower for creatinine (29-84 vs. 62-115 µmol/L), and more variable for potassium (2.7-7.9 vs. 3.5-5.0 mmol/L) and sodium (130-141 vs. 136-145 mmol/L). Cesarean section was associated with higher potassium and lower glucose, multiple births with higher chloride and creatinine and lower glucose, and SGA with lower glucose. CONCLUSION Cord blood values varied across the GA range with increases in sodium, chloride, and creatinine, while glucose remained steady. Average preterm reference values were higher than term values for potassium and chloride. Preterm reference values differed from published adults' reference values. The changes across GA and by delivery mode, SGA, and being a multiple, which may have direct implications for neonatal care and fluid management. KEY POINTS · Cord blood electrolyte, creatinine, and glucose values vary across neonatal gestational age.. · Average preterm cord values of potassium and chloride were higher than term values.. · Cord reference values differ by delivery mode, growth, and multiple impacting neonatal care decisions..

Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Abstract
The study presented a powder processing method involving calcination and subsequent carbonation in the synthesis of precipitated calcium carbonate (PCC) for recycling green mussel shells, which contain a high calcium carbonate content. The purity of portlandite [Ca(OH)2] as a result of calcination and subsequent moisture absorption during storage was verified using the XRD-Rietveld method. Further quantitative XRD Rietveld analysis of the PCC product confirmed the presence of vaterite (55.20 wt.%) and calcite (44.80 wt.%) minerals after carbonation process of the calcined powder product. The SEM examination of this product revealed particle aggregates of non-uniform polyhedral and cubical grains of varying small and large sizes. The FTIR analysis also confirmed that calcination and subsequent hydration of mussel shell powder yielded pure portlandite, whereas the carbonation yielded PCC polymorphism. As a result, this powder processing method is simple to scale and reduces the cost of PCC synthesis, which is critical for practical applications. The current study demonstrated that the powder processing method for recycling green mussel shells as starting materials in biomedical applications is technically feasible.

Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Abstract
Background Neonatal hypoxic ischemic encephalopathy (HIE) after perinatal asphyxia is a serious clinical condition that may result in permanent neurologic deficits or death. There is an increased incidence of persistent pulmonary hypertension of the newborn (PPHN) in asphyxiated infants. Due to the high disease burden of HIE, studying its altered cardiopulmonary hemodynamics might identify those patients at highest risk for adverse outcome early on. Objectives To investigate the relationship between severity of PPHN and the extent of short-term brain injury in infants with moderate to severe HIE who received therapeutic hypothermia (TH). Design/Methods Retrospective cohort study of 230 TH-treated HIE infants. PPHN was defined and graded clinically and based on echocardiography findings. The primary outcome was the presence of HIE changes on brain MRI and/or death within the first month of life according to the diagnosis and severity of PPHN. Secondary outcomes were the pattern of HIE on brain MRI; abnormal electroencephalogram (EEG) background, clinical, or electrographic seizures, or need for anti-ictal treatment; clinical and laboratory differences between HIE babies with and without PPHN. A logistic regression model was performed to identify PPHN severity as risk factor for moderate-to-severe brain injury or death. Results Brain injury was not found to be different between the two groups according to presence of PPHN whether clinically or based on echocardiography. However, the combined outcome of severe brain injury or death was higher in the clinical PPHN group vs non-PPHN (32.6 vs 22.8%, p=0.014), and early exit from TH due to severe PPHN was associated with the highest mortality (71.4%). Death was found to have a relationship with the severity of PPHN based on echocardiography, with the highest incidence in severe PPHN (36.0 vs 7.7% and 10.0% in the severe, moderate, and mild PPHN groups, respectively, p=0.002). Infants with clinical PPHN were sicker with higher ventilation needs and worse laboratory values compared to those without PPHN. None of the other outcomes were different among the two groups. Conclusion In infants with HIE treated with TH, PPHN was not associated with increased risk of brain injury as evident on MRI, nor clinical or electrographic seizure burden. However, mortality was higher in the most severe PPHN categories. ![]()

Abstract
Introduction Lymphangiomas are rare, congenital malformations arising from lymphatic hyperplasia. More than 90% of cases are found in children under 2 years of age. Cystic lymphangiomas usually occur in the neck and axillary region and only rarely extend to the mediastinum. Case Description We present the case of a middle-aged woman who presented with dyspnoea and productive cough. A chest x-ray showed right lower medial lung opacity, and a CT scan of the thorax showed a cystic mediastinal mass, encroaching on the superior vena cava and approaching the trachea and mainstem bronchus. An anterior thoracotomy with tumour resection was performed to relieve compression symptoms. The final pathology report confirmed the diagnosis of mediastinal lymphangioma. Discussion Lymphangioma should be considered as one of the differential diagnoses when mediastinal widening is found on chest x-ray, and it should be investigated further with a CT scan and biopsy. Infiltration of surrounding structures can cause compression symptoms and can also make surgical resection more challenging. LEARNING POINTS

Abstract
We report a case of a 59-year-old male who developed pancytopenia and multiorgan failure attributed to copper deficiency from exogenous consumption of zinc tablets. During the six months preceding his presentation, he had experienced increasing shortness of breath, lightheadedness, and fatigue. Laboratory studies revealed pancytopenia with profound anemia (hemoglobin level 2.8 g/dL) along with evidence of acute kidney injury and acute heart failure; the patient was presumed to have multiorgan failure due to profound anemia. Bone marrow biopsy revealed dyspoiesis suggestive of myelodysplastic syndrome (MDS). There were no cytogenetic abnormalities observed. However, the blood workup analysis found low copper and ceruloplasmin levels, whereas zinc levels were excessively elevated (257 mg/dL). Upon inquiry, the patient reported taking an over-the-counter zinc supplement of an unknown quantity for over a year. After two months of copper treatment, his blood count returned to normal. This case highlights a rare presentation of zinc-induced copper deficiency resulting in pancytopenia and severe anemia-related multiorgan failure. A growing number of hematological disorders are being linked to copper deficiency. Copper deficiency pancytopenia is a reversible condition that often goes unnoticed and can be misdiagnosed as MDS because it has similar hematological characteristics.

Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
Obesity has become a major public health problem with increased prevalence. It is associated with cardiovascular mortality. Phentermine is approved for short-term obesity treatment in conjunction with lifestyle modifications. Palpitation is a well-documented side effect of phentermine. However atrial fibrillation (AF) is rarely reported. We present a case of new-onset AF in a healthy woman who was recently started on phentermine for weight loss.

Abstract
Iron deficiency anemia is the leading cause of anemia all over the world. Iron deficiency is known to cause reactive thrombocytosis. However, arterial thrombosis secondary to reactive thrombocytosis is a rare entity. In this article, we present a case of a 37-year-old female with recurrent arterial thrombosis due to severe thrombocytosis caused by iron deficiency anemia. The patient developed spleen and kidney infractions, as well as abdominal aortic thrombosis. She was subsequently treated with iron and aspirin with an improvement of the anemia and thrombocytosis, with no further thrombotic complications. Arterial thrombosis is a very serious condition as the thrombus can embolize to carotid arteries leading to stroke or to peripheral blood vessels causing peripheral ischemia and gangrene. Iron deficiency anemia is a reversible cause of thrombocytosis that can be treated very easily to avoid thrombotic complications.

Abstract
Left ventricular (LV) thrombosis usually occurs as a complication of acute anterior myocardial infarction (MI) and dilated cardiomyopathy. It also occurs in patients with a hypercoagulable state. However, in the setting of normal systolic function, LV thrombi are extremely rare. We present a case of a healthy woman who had LV thrombus despite normal LV systolic function that presented as an acute aortoiliac embolism.

Abstract
Objective: To determine the nationwide prevalence of malignant neoplasms (excluding hepatocellular carcinoma-HCC) in hospitalized liver transplant recipients and to study the hospital utilization, and mortality to the incidence of malignancies. To the best of our knowledge, few epidemiological studies addressed outcomes in post-liver transplant patients, such as the annual number of hospitalizations, mortality, patient characteristics regarding malignancies. Methods: NIS database was queried between 2016 and 2018 to retrieve records of patients admitted with a principal or secondary diagnosis of liver transplant following the International Classification of Diseases, tenth Revision (ICD-10). The population was divided into case and control groups according to the presence and absence of malignant neoplasm (MN) except for HCC. We also compared the incidence of MN in LTX patients and non-LTX matched cohort. Results: A total of 7.28% admissions were associated with malignant neoplasms (except HCC) in LTX patients. Lymphomas, respiratory, gastrointestinal (excluding HCC), leukemia, and head/neck were commonest cancers with estimated admission rates of 0.97%, 0.90%, 0.80%, 0.53%, and 0.49%, respectively. Lung cancer was the most frequent malignant neoplasm among White and Black racial/ethnic groups (15.78% and 14.8%), whereas lymphoma was pervasive among Hispanics (20.3%). Lung cancer had the highest in-hospital mortality (10.55%), followed by the cancer of the nervous system (9.09%). The LTX and non-LTX cohort comparison showed that LTX patients are at increased risk of head and neck cancers, skin cancers, lymphomas, tumors, and Myelodysplastic syndrome. According to a multivariate analysis, a statistically significant association existed between malignant neoplasms in LTX patients and the following factors: increasing age (P < .001), higher mortality (P < .001), females with 29% lesser odds than males (P < .001), Black race and Hispanic ethnicity with 20% and 26% lesser odds as compared to White (P < .05). Clinical factors included smoking, Alcoholic cirrhosis, Hepatitis B, and Hepatitis C, were statistically significant risk factors of post-liver transplantation malignancies. Conclusions: Malignancies were frequent among elderly patients and predominantly in males. Lymphoproliferative diseases were the most prevalent malignancy types, followed by respiratory/lung cancer- which showed the highest mortality risk of all cancers. LTX patients are at increased risk of head and neck cancers, skin cancers, lymphoma, tumors, and Myelodysplastic syndrome compared to non-LTX patients.

Abstract
Legionella pneumonia is a gram-negative bacterial infection commonly associated with aerosol transmission from contaminated water sources. Impaired immunity leads to delayed clearance of infection and further predisposes individuals with Legionella pneumonia at risk of developing complications. We present a case report on a renal transplant patient with comorbid cardiac and renal dysfunction who developed community-acquired Legionella pneumonia. The case emphasizes the importance of adopting a multidisciplinary approach when managing Legionella infection in patients with multiple comorbidities and immunosuppressive states.

Abstract
BACKGROUND Refractory septic shock in neonates is still associated with high mortality, necessitating an alternative therapy, despite all currently available treatments. This study aims to assess the vasopressor effect of methylene blue (MB) in comparison to terlipressin (TP) as adjuvant therapy for refractory septic shock in the preterm neonate. METHODS A double-blinded randomized controlled trial was conducted in the Neonatal Intensive Care Units at Ain Shams University, Egypt. Thirty preterm neonates with refractory septic shock were randomized to receive either MB or TP as an adjuvant to conventional therapy. Both MB and TP were administered as an intravenous loading dose followed by continuous intravenous infusion. The hemodynamic variables, functional echocardiographic variables, and oxidant stress marker were assessed over a 24 h period together with the side effects of MB. RESULTS MB causes significant improvement in mean arterial blood pressure with a significant decrease of the norepinephrine requirements (1.15±0.21μm/kg/min at baseline vs. 0.55±0.15μm/kg/min at 24 h). MB infusion causes an increase of the pulmonary pressure (44.73±8.53 mmHg at baseline vs. 47.27±7.91 mmHg after 24 h) without affecting the cardiac output. Serum malonaldehyde decreased from 5.45±1.30 nmol/mL at baseline to 4.40±0.90 nmol/mL at 24 h in the MB group. CONCLUSION Administration of MB to preterm infants with refractory septic shock showed rapid increases in systemic vascular resistance and arterial blood pressure with minimal side effects.

Abstract
Gastric neuroendocrine tumors (GNETs) are rare and subdivided into type I, type II, and type III. Types I and II are gastrin-dependent and are usually benign, whereas type III is gastrin-independent and more aggressive. Type I accounts for 70-80% of all GNETs. Most of them are asymptomatic and incidentally detected on endoscopy. It can sometimes present with iron and B12 deficiency, dyspepsia, and less commonly with an upper GI bleed. We present a case of type I GNET who came to the hospital with melena and esophagogastroduodenoscopy (EGD) showing a 3-cm bleeding polyp and histopathology revealing a well-differentiated neuroendocrine tumor with angioinvasion.

Abstract
Herpes simplex (HSV) esophagitis is usually identified in patients with significant immunosuppressive conditions such as AIDS. Short course of immunosuppressive therapy is an uncommon risk factor for this condition. We present a case of acute gastrointestinal bleeding secondary to HSV type 1-induced esophageal ulcers. A 63-year-old woman developed acute hypoxic hypercapnic respiratory failure. Past medical history was significant for COPD for which the patient was taking short-acting bronchodilator inhalers. The patient was intubated and started on mechanical ventilation. Intravenous Solu-Medrol 40 mg Q6 was started. Hospital course was complicated by sepsis of unknown source. Empiric broad-spectrum antibiotic therapy was started. On the 11th hospital day, the patient experienced multiple episodes of coffee ground emesis. There was abdominal tenderness on physical examination. Significant laboratory results were lipase 1,911 U/L and lymphopenia (ALC = 300/mm3). Endoscopy revealed severe erosive esophagitis and multiple punched-out ulcerations of the esophagus. Empiric treatment with valacyclovir 500 mg OD was started. The patient required PEG tube insertion for dysphagia. Complete resolution of esophagitis was noted then. Immunohistochemical staining for HSV was strongly positive in the cells with inclusions. Short course of intravenous corticosteroids is an uncommon cause of HSV-1 esophagitis. Corticosteroid-induced lymphopenia impedes underlying cellular immunity, which might explain the reactivation of latent herpes and esophageal ulcer formation. Given the rarity of the disease, evidence of treatment is available from case reports only. We found complete resolution of esophageal ulcers after the patient received valacyclovir therapy for 10 days.

Abstract
Thyroid storm is an extremely rare yet life-threatening medical emergency. It results from the decompensation of undiagnosed or undertreated hyperthyroidism in the presence of an acute stressor such as trauma to the thyroid, infections, acute iodine load, withdrawal from the antithyroid medication, or surgical procedures (including thyroid surgery). Clinical features of thyroid storm include hyperthermia, tachycardia, respiratory distress, gastrointestinal and hepatic symptoms, and central nervous system dysfunction. It is primarily a clinical diagnosis, further aided by abnormal thyroid function tests. Thyroid storm is associated with significant mortality and morbidity - the latter mostly related to complications from thyrotoxicosis or hyperthyroidism. Treatment with iodine (or iodide-ionized active form of iodine) supplements or with radioactive iodine, also known as radioiodine, such as in the treatment of thyroid cancer, is a common and mostly safe practice; however, iodine contrast in tomography imaging may precipitate a thyroid storm in sporadic cases. Here, we report a remarkable case of a 62-year-old African American female with a history of total thyroidectomy secondary to follicular thyroid cancer three years before the current presentation; she developed left lung pneumonia complicated by thyroid storm status post a computed tomography angiogram of the abdomen. She exhibited signs and symptoms of thyrotoxicosis a few days after receiving the iodinated contrast. The recommended daily iodide intake for adults with hyperthyroidism is about 150 mcg per day, while a computed tomography scan exposes patients to 14 to 35 million mcg of iodinated contrast at once, which could have triggered a storm. In this case, the patient was diagnosed with thyroid storm, which was presumed to be a consequence of the Jod-Basedow phenomenon secondary to metastatic thyroid carcinoma lesions discovered later. This clinical diagnosis was reinforced by laboratory results showing elevated serum free T4 and undetectable thyroid-stimulating hormone. She was treated with supportive measures, steroids, beta-blockers, and antithyroid medications with a positive outcome. This case demonstrated that, in the setting of recurrent metastatic thyroid cancer, clinicians should approach the use of intravenous iodine medium contrast in imaging with some level of caution when dealing with patients at risk of thyrotoxicosis or with underlying hyperthyroidism state at the brink of a storm.

Abstract
Background: Essential Oils (EOs) are natural metabolic products of plants that contain a condensed chemical hydrophobic liquid compounds. The aim of this study was to evaluate inhibitory effects of EOs of Cinnamon zeylanicum and Myristica fragrans against Brucella abortus 544 inoculated in fresh Baladi cheese.
Methods: Fresh Baladi cheese was manufactured from experimentally contaminated milk with B. abortus 544 in combination of EOs of C. zeylanicum or M. fragrans. Cheese samples were periodically subjected to further microbiological surveys at different storage times (0, 1, 24, 48, 72, and 96 h). The inhibition zone diameter and Minimum Inhibitory Concentration (MIC) against tested strain were also determined. Statistical analyses were conducted by GraphPad Prism Statistical Software.
Results: The inhibition zone diameter of the paper disk were 9.5±0.5 and 16±0.57 mm at 1% concentration of M. fragrans and C. zeylanicum EOs, respectively; and 15±0.28 and 21±0.76 mm at 5% concentration of M. fragrans and C. zeylanicum EOs, respectively. The values of inhibition zone diameters were significantly (p<0.0001) different between the two selected concentrations of 1% and 5% for the studied EOs. Also, anti-Brucella activity of C. zeylanicum was significantly (p<0.0001) more than that of M. fragrans EO.
Conclusion: Due to the appropriate anti-Brucella activity, C. zeylanicum EO could be applied as an effective natural preservative in the production of fresh Baladi cheese. Conversely, using M. fragrans EO could not protect the fresh Baladi cheese against Brucella.

Abstract
The incidence of leptospirosis seems to be on the rise and could be an alarming indirect indication of a global re-emergence. It is a potential public health threat when dogs are speculated to be involved in the transmission of leptospirosis through possible subclinical harbouring of Leptospira spp. and subsequent shedding into the environment. This study aimed to detect anti-leptospiral antibodies among dogs and their handlers using the microscopic agglutination test (MAT). Blood samples from 266 apparently healthy dogs and 194 dog handlers were collected at four working dog organisations and four dog shelters. Serum samples were tested using MAT against 20 leptospiral serovars with a cut-off titre >=1:100 (dog) and >=1:50 (dog handlers). Seventy dogs (70/266; 26.3%) were seropositive mainly against serovars Icterohaemorrhagiae, Ballum, Bataviae and Javanica (titres ranged: 1:100-1:800). Sixty-seven dog handlers (67/194; 34.5%) were seropositive mainly against serovars Grippotyphosa, Icterohaemorrhagiae and Malaysia (titres ranged: 1:50-1:200). Dogs were seropositive due to exposure, vaccination or active infection. Seropositive dog handlers could indicate exposure or active infection. This shows the potential of dogs in maintaining and spreading the infection in Malaysia. Due to the occupational risk as a result of frequent contact with dogs and exposure to contaminated environments, dog handlers should be made aware of the presence of this zoonotic disease.

Abstract
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a respiratory pathogen with remarkable properties of multisystem involvement and numerous complications. The coronavirus disease of 2019 (COVID-19) presenting as stroke is becoming more common. Herein, we describe an unusual case of COVID-19 in a patient who initially presented with myalgia, fatigue, loss of taste and smell, and non-specific memory impairment. Two months after infection with SARS-CoV-2, the patient presented with acute onset of right-sided weakness, sensory loss, and worsening cognitive impairment. Reverse transcription-polymerase chain reaction was performed to detect the SARS-CoV-2 virus, and the results were positive at the time of initial infection as well as during the current admission. Neuroimaging suggested a subacute ischemic infarct in the middle cerebral artery. The patient was re-tested for SARS-CoV-2 and found to be positive, but the cycle threshold was high (40.4) along with a positive test for immunoglobulin-G (IgG) for SARS-CoV-2. This report highlights a unique case of stroke-related to COVID-19 infection in a middle-aged woman with otherwise mild symptomatic illness. The patient had a chronic ischemic stroke with delayed presentation two months after the initial symptomatic viral infection. This case underscores the importance of neurological assessment as well as timely evaluation of patients presenting with COVID-19 and any neurological concerns to recognize stroke as a complication of COVID-19 promptly.

PURPOSE To identify the key set of glaucoma surgery outcome measures considered most important and practical to collect by glaucoma specialists. METHODS One hundred two glaucoma specialists (57 members of the UK and Eire Glaucoma Society (UKEGS) and 45 members of the European Glaucoma society (EGS)) took part in an Online Delphi exercise. The RAND/UCLA appropriateness method was used analyse data from each round and generate a disagreement index. RESULTS Participants agreed on 13 baseline data points and 12 outcomes that were considered important and practical to collect. For intraocular pressure (IOP) percentage reduction in IOP from baseline (last three IOP readings pre-op) and reduction below a specified target were considered important. For visual fields, change in a global visual field index, e.g. MD, and development of progression as assessed by linear regression were considered important. From a safety perspective, any visual loss resulting in a doubling of the minimal angle of resolution, loss of 5 dB or more of visual field or development of advanced field loss (Hodapp Parrish Anderson Stage 4) was considered important. The importance of routinely using patient reported outcome measures (PROMs) was highlighted. Consensus suggested that outcomes of glaucoma treatments should be reported at 1, 5 and 10 years. CONCLUSIONS There was broad consensus on a minimum dataset for reporting the outcomes of glaucoma surgery and outcome measurement intervals.

Abstract
This study explores the use of a long fragment of the mitochondrial cytochrome oxidase subunit 1 (CO1) marker to elucidate the genetic diversity of Aedes albopictus sampled from urban and forested regions in Peninsular and East Malaysia. A total of 36 samples were collected from 5 localities from which its genetic variability was analysed. 33 distinct mtDNA haplotypes were identified following the amplification and sequencing of the concatenated CO1 gene. The analysed region of the CO1 gene identified substantial levels of genetic diversity among mosquitoes in urban populations and revealed unique genealogical relationships between local isolates as revealed in the haplotype network. This study highlights the reliability of the long CO1 fragment to identify genetic divergence of Aedes albopictus which can be utilized in forthcoming studies.

Abstract
Risk Assessment (RA) is the key element of the Quality by Design (QbD) approach recommended by the pharmaceutical regulatory bodies. This research paper aimed to implement the regulatory requirements, the QbD thinking and the RA from the first steps of the oral peptide formulation development. The authors intended to give a general recommendation about the application possibilities of this methodology, to demonstrate the risk factors and the required decision points. Later, this paper presents a concrete development in practice. This case study shows the QbD and RA based early phase development of the GLP 1 analog, Liraglutide, an antidiabetic peptide drug mainly used in the treatment of type 2 Diabetes Mellitus. The objective here was to design Liraglutide encapsulated polymeric nanoparticles for oral delivery and the progress of their RA based development is presented. In this case, the particle size, the encapsulation efficiency, and the drug loading were found as the most critical quality attributes, the polymer concentration, the drug concentration, the w2/o ratio, the stabilizer concentration and polymer type were identified by the criticality rating as having the greatest impact on the product quality among the critical material attributes, finally the sonication time and sonication power were selected as the most critical elements of the production process. The results showed the importance of the risk factor-focused development in the oral peptide pharmaceutical formulations, and underlined the importance of the profound planning phase even in such cases. The formulation of an oral peptide delivery system is associated with several risks, but their priority ranking helps to focus on the resources (human, financial, time) related to the final product quality aimed at.

Abstract
AIMS To determine the effects of herbal therapies on hot flushes and at least one other symptom including, sleep, mood, cognition, and pain that women experience during the menopausal transition and early postmenopause. METHODS An extensive search of PubMed/Medline, CINAHL Plus, PsycInfo, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Web of Science, EMBASE, AMED, and Alt-Health Watch for randomized, controlled trials reported in English between January 2004 and July was conducted by an experienced reference librarian. There were 1193 abstracts identified but only 58 trials examined effectiveness of therapies for hot flushes and at least one additional co-occurring symptom. RESULTS Seventeen studies used herbal preparation including seven studies of black cohosh, two studies of black cohosh mixed with other herbals, and eight studies of other herbals. Of these, one study of black cohosh, two studies of black cohosh mixed with other herbals, and four other herbal studies had significant effects on hot flushes and at least one additional co-occurring symptom. The adverse events of herbal therapies were various, ranging from mild to moderate and women were generally tolerant of the preparations. CONCLUSIONS Black cohosh mixed with other herbals, Rheum rhaponticum, and French maritime pine bark had significant effects on hot flushes and at least one other symptom. These herbal therapies may be a promising alternative treatment to hormonal treatment. Future studies should classify women based on their menopausal stages, report each symptom separately, have adequate sample size, focus on multiple co-occurring symptoms, and target symptom management of menopausal symptoms.

Abstract
AIMS Although most women experience symptom clusters during the menopausal transition and early postmenopause, investigators reporting clinical trial effects for hot flushes often omit co-occurring symptoms. Our aim was to review controlled clinical trials of mind-body therapies for hot flushes and at least one other co-occurring symptom from these groups: sleep, cognitive function, mood, and pain. METHODS An experienced reference librarian performed an extensive search of PubMed/Medline, CINAHL Plus, PsycInfo, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Web of Science, EMBASE, AMED, and Alt-Health Watch for randomized controlled trials reported in English between 2004 and July 2011. Of 1193 abstracts identified, 58 trials examining effectiveness of therapies for hot flushes and at least one additional co-occurring symptom of interest were identified. RESULTS Eight trials (ten publications) examined relaxation, yoga, or exercise. Physical activity/exercise trials (six) yielded mixed results; only one significantly reduced hot flushes and mood symptoms. Of two relaxation therapy trials, only mindfulness-based stress reduction training reduced sleep and mood symptoms and had within-group treatment effects on hot flushes. Yoga (one trial) significantly reduced hot flushes and improved cognitive symptoms more than exercise, and also had within-group effects on sleep and pain symptoms. CONCLUSIONS Studies of mind-body therapies for hot flushes increasingly measure multiple symptom outcomes, but few report treatment effects in ways that allow clinicians to consider symptom clusters when prescribing therapies. Future studies need to measure and report results for individual symptoms or group like symptoms together into subscales rather than use subscales with mixed dimensions. Trials with larger numbers of participants are essential to allow evaluation of these therapies on multiple co-occurring symptoms.

Abstract
Purpose To study the effects of varying lipid concentrations, lipid and oil ratio, and the addition of propylene glycol and lecithin on the long-term physical stability of nanostructured lipid nanocarriers (NLC), skin hydration, and transepidermal water loss. Methods The various NLC formulations (A1–A5) were prepared and their particle size, zeta potential, viscosity, and stability were analyzed. The formulations were applied on the forearms of the 20 female volunteers (one forearm of each volunteer was left untreated as a control). The subjects stayed for 30 minutes in a conditioned room with their forearms uncovered to let the skin adapt to the temperature (22°C ± 2°C) and humidity (50% ± 2%) of the room. Skin hydration and skin occlusion were recorded at day one (before treatment) and day seven (after treatment). Three measurements for skin hydration and skin occlusion were performed in each testing area. Results NLC formulations with the highest lipid concentration, highest solid lipid concentration, and additional propylene glycol (formulations A1, A2, and A5) showed higher physical stability than other formulations. The addition of propylene glycol into an NLC system helped to reduce the particle size of the NLC and enhanced its long-term physical stability. All the NLC formulations were found to significantly increase skin hydration compared to the untreated controls within 7 days. All NLC formulations exhibited occlusive properties as they reduced the transepidermal water loss within 7 days. This effect was more pronounced with the addition of propylene glycol or lecithin into an NLC formulation, whereby at least 60% reduction in transepidermal water loss was observed. Conclusion NLCs with high lipid content, solid lipid content, phospholipid, and lecithin are a highly effective cosmetic delivery system for cosmetic topical applications that are designed to boost skin hydration.
