The goal is to provide foundational data that could spearhead more extensive, prospective research into understanding the influences of micronutrient levels on the nocturnal patterns of hypertension, possibly aiding in identifying potential therapeutic strategies to reduce cardiovascular risk in this demographic. The research employed a retrospective design to analyze the micronutrient levels, including ferritin, folic acid, vitamin B12, and vitamin D, in a limited sample size from a single hospital. However, it is worth noting that the study did not scrutinize other potentially relevant micronutrients and biomarkers and lacked information on potential confounding factors such as lifestyle and dietary habits, physical activity levels, and specific details on antihypertensive medications used.

Article Synopsis
  • Epilepsy is a common chronic brain disease with genetic roots, and this study aims to analyze facial measurements in both epilepsy patients and healthy individuals to find characteristics that might influence epilepsy diagnosis.
  • The research included 120 epilepsy subjects and 60 healthy controls, measuring different facial angles and lengths using CT scans to compare the two groups.
  • The results indicated specific facial measurements were significantly different in epilepsy patients, suggesting that epilepsy may influence certain facial features, though no age-related changes were observed in healthy subjects.

Unlabelled: Oxaliplatin-induced immune thrombocytopenia is a rare but potentially serious complication of chemotherapy. We present the case of a 55-year-old man with stage 4 pancreatic carcinoma who developed immune thrombocytopenia during the 18 cycle of folinic acid, fluorouracil, irinotecan, and oxaliplatin (FOLFIRINOX) chemotherapy, immediately after oxaliplatin infusion. Despite treatment with methylprednisolone and platelet infusion, the patient's platelet count remained low.

Introduction: The aim of the study was to analyse the clinical and demographic features of infants with gestational age (GA) of 32-37 weeks and birth weight (BW) of >1,500 g who developed treatment requiring retinopathy of prematurity (ROP).

Methods: Data on the infants with a GA of 32-37 weeks and BW >1,500 g who developed treatment requiring ROP (TR-ROP) were collected retrospectively from the 33 ROP centres in Turkiye. GA, BW, type of hospital, neonatal intensive care units (NICUs) level, presence of an ophthalmologist and neonatologist in the same hospital, length of stay in NICU, duration of oxygen therapy, comorbidities, type of ROP, and timing for TR-ROP development were analysed.

Article Synopsis
  • Sodium-glucose cotransporter-2 inhibitors (SGLT2i) help lower blood glucose and sodium levels by promoting their excretion in urine, leading to benefits like reduced heart failure (HF) hospitalizations in patients with type 2 diabetes (T2DM) and cardiovascular (CV) risks.
  • Clinical trials like DAPA-HF and EMPEROR-Reduced demonstrate that SGLT2i medications (dapagliflozin and empagliflozin) significantly reduce CV mortality and HF hospitalizations in heart failure patients, whether they have T2DM or not.
  • Recent studies, including EMPEROR-Preserved and DELIVER, also support the effectiveness of SGLT2is in treating heart

Wafer Level Vacuum Packaging of MEMS-Based Uncooled Infrared Sensors.

Micromachines (Basel)

July 2024

MikroSens Elektronik San ve Tic A.S., Ankara 06530, Turkey.

This paper introduces a cost-effective, high-performance approach to achieving wafer level vacuum packaging (WLVP) for MEMS-based uncooled infrared sensors. Reliable and hermetic packages for MEMS devices are achieved using a cap wafer that is formed using two silicon wafers, where one wafer has precise grating/moth-eye structures on both sides of a double-sided polished wafer for improved transmission of over 80% in the long-wave infrared (LWIR) wavelength region without the need for an AR coating, while the other wafer is used to form a cavity. The two wafers are bonded using Au-In transient liquid phase (TLP) bonding at low temperature to form the cap wafer, which is then bondelectrical and Electronics d to the sensor wafer using glass frit bonding at high temperature to activate the getter inside the cavity region.

Various research endeavours are designed to identify ecosystem services, assess their spatial distribution, and prioritize them in a given forest landscape. The Turkish State Forest Organization has introduced an ecosystem-based multiple-use forest management philosophy since 2008, which emphasizes the need for identifying and allocating ecosystem services to each forest planning unit. This paper aims to investigate the use of Multiple Criteria Decision Analysis (MCDA) techniques and explores their effectiveness and suitability in identifying and allocating ecosystem services to forest units, considering scientific suitability, stakeholder engagement and the sustainability concept in the context of ecosystem-based forest management decision-making processes in a case study area of Turkey.
