Sweatings, the exudates that leach out from fermenting fruits during rambutan fruit fermentation are considered as
a waste by-product and are allowed to be drained off. This could lead to a pollution problem. Besides, it is a waste if
the sweatings are possible to be transformed into food products and ingredients. However, prior transformation, the
fundamental knowledge of the sweatings should be understood. Hence, the main aim of this study was to investigate
the physicochemical properties of sweatings as affected by fermentation time and turning intervals during natural
fermentation of rambutan fruits. In this study, peeled rambutan fruit was fermented for 8 days and turned. Different
batches of the fruits were turned every 24, 48 or 72 h and sweatings from the process were collected and analyzed.
The results showed that fermentation time significantly reduced (p<0.05) the yield, pH and sucrose content of the
sweatings by 79-84%, 32-33%, 76.5-80.8%, respectively. Fermentation time also significantly increased (p<0.05) the
titratable acidity, total soluble solids, fructose, glucose, total sugar, citric acid, lactic acid, acetic acid and ascorbic
acid contents of the sweatings by 5.6-6.0, 1.5-1.6, 2.4-2.6, 2.1-2.5, 1.0-1.1, 5.7-6.5, 2.4-2.6, 2.1-2.5 and 2.6-2.8 folds,
respectively. However, turning intervals did not significantly affect (p>0.05) the physicochemical properties of the
sweatings. High concentrations of sugars and organic acids allow the sweatings to have a balance of sweet and sour
taste and they are suitable to be used in the production of syrup, soft drinks, jam, jelly, marmalade and vinegar.

Fulltext Heat acclimation attenuates the increased sensations of fatigue reported during acute exercise-heat stress

Willmott AGB, Hayes M, James CA, Gibson OR, Maxwell NS

Temperature (Austin), 2019 Sep 19;7(2):178-190.
PMID: 33015245 DOI: 10.1080/23328940.2019.1664370

Athletes exercising in heat stress experience increased perceived fatigue acutely, however it is unknown whether heat acclimation (HA) reduces the magnitude of this perceptual response and whether different HA protocols influence the response. This study investigated sensations of fatigue following; acute exercise-heat stress; short- (5-sessions) and medium-term (10-sessions) HA; and between once- (ODHA) and twice-daily HA (TDHA) protocols. Twenty male participants (peak oxygen uptake: 3.75 ± 0.47 L·min-1) completed 10 sessions (60-min cycling at ~2 W·kg-1, 45°C/20% relative humidity) of ODHA (n = 10) or non-consecutive TDHA (n = 10). Sensations of fatigue (General, Physical, Emotional, Mental, Vigor and Total Fatigue) were assessed using the multi-dimensional fatigue scale inventory-short form pre and post session 1, 5 and 10. Heat adaptation was induced following ODHA and TDHA, with reductions in resting rectal temperature and heart rate, and increased plasma volume and sweat rate (P

Single-centre study of therapeutic drug monitoring of posaconazole in lung transplant recipients: factors affecting trough plasma concentrations

Jeong W, Snell GI, Levvey BJ, Westall GP, Morrissey CO, Wolfe R, et al.

J Antimicrob Chemother, 2018 Mar 01;73(3):748-756.
PMID: 29211913 DOI: 10.1093/jac/dkx440

Objectives: This study describes therapeutic drug monitoring (TDM) of posaconazole suspension and modified release (MR) tablets in lung transplant (LTx) recipients and evaluates factors that may affect posaconazole trough plasma concentration (Cmin).
Methods: A single-centre, retrospective study evaluating posaconazole Cmin in LTx recipients receiving posaconazole suspension or MR tablets between January 2014 and December 2016.
Results: Forty-seven LTx patients received posaconazole suspension, and 78 received the MR tablet formulation; a total of 421 and 617 Cmin measurements were made, respectively. Posaconazole was concurrently administered with proton pump inhibitor in ≥ 90% of patients. The median (IQR) of initial posaconazole Cmin following 300 mg daily of posaconazole tablet was significantly higher than that of 800 mg daily of posaconazole suspension [1.65 (0.97-2.13) mg/L versus 0.81 (0.48-1.15) mg/L, P

Uncontrolled hypertension, palpitation and sweating in young female - A rare cause

Sandeep HV, Sarat KS, Ng LT

Med J Malaysia, 2016 02;71(1):39-40.
PMID: 27130746

Extra-adrenal /retroperitoneal paraganglioma is a rare cause of hypertension in young with increased incidence of metastasis as compared to adrenal pheochromocytoma. We present a case of a young female with history of headache, nausea/vomiting, palpitations, uncontrolled hypertension, heat intolerance and diaphoresis. The 24-hour urine catecholamine levels were elevated. Clinical diagnosis of pheochromocytoma was made and further evaluation with Computed Tomography (CT) scan of the adrenals revealed extradrenal para-aortic retroperitoneal mass in keeping with paraganglioma. Gallium-68 DOTATE positron emission tomography-CT scan (PET-CT) confirmed the diagnosis without evidence of metastatic foci.

Fulltext Parotid swellings: report of 110 consecutive cases

Arshad AR

Med J Malaysia, 1998 Dec;53(4):417-22.
PMID: 10971987

Parotid swellings are uncommon. Over a twelve-year period, 110 cases of parotid swellings were treated at the Department of Plastic Surgery, Hospital Kuala Lumpur, of which 97 cases were histologically proven to be parotid tumours. 75% of these tumours were benign tumours, and 80% of the benign tumours were pleomorphic adenomas. Among the malignant tumours, 6 cases were adenoid cystic carcinoma and 5 were carcinoma ex-pleomorphic adenoma. There were equal number of male to female patients, with an age range of 14 to 83 years. There is a positive correlation between the final histological diagnosis and FNAC results in 74% of cases. Surgical treatment of choice for benign parotid tumours was near-total parotidectomy whilst for malignant tumours was total radical parotidectomy with sural nerve graft.
