Background:
It is well known that a large number of patients with diabetes also have dyslipidemia, which significantly increases the risk of cardiovascular disease (CVD). This study aimed to evaluate the efficacy and safety of combination drugs consisting of metformin and atorvastatin, widely used as therapeutic agents for diabetes and dyslipidemia.
Methods:
This randomized, double-blind, placebo-controlled, parallel-group and phase III multicenter study included adults with glycosylated hemoglobin (HbA1c) levels >7.0% and <10.0%, low-density lipoprotein cholesterol (LDL-C) >100 and <250 mg/dL. One hundred eighty-five eligible subjects were randomized to the combination group (metformin+atorvastatin), metformin group (metformin+atorvastatin placebo), and atorvastatin group (atorvastatin+metformin placebo). The primary efficacy endpoints were the percent changes in HbA1c and LDL-C levels from baseline at the end of the treatment.
Results:
After 16 weeks of treatment compared to baseline, HbA1c showed a significant difference of 0.94% compared to the atorvastatin group in the combination group (0.35% vs. −0.58%, respectively; P<0.0001), whereas the proportion of patients with increased HbA1c was also 62% and 15%, respectively, showing a significant difference (P<0.001). The combination group also showed a significant decrease in LDL-C levels compared to the metformin group (−55.20% vs. −7.69%, P<0.001) without previously unknown adverse drug events.
Conclusion
The addition of atorvastatin to metformin improved HbA1c and LDL-C levels to a significant extent compared to metformin or atorvastatin alone in diabetes and dyslipidemia patients. This study also suggested metformin’s preventive effect on the glucose-elevating potential of atorvastatin in patients with type 2 diabetes mellitus and dyslipidemia, insufficiently controlled with exercise and diet. Metformin and atorvastatin combination might be an effective treatment in reducing the CVD risk in patients with both diabetes and dyslipidemia because of its lowering effect on LDL-C and glucose.

Clonazepam, a 7-nitrobenzodiazepine, has been used for the treatment of various neuropsychiatric disorders such as seizures, sleep disorders, panic disorders, anxiety, and movement disorders. However, clonazepam is officially approved as a therapeutic drug only for epilepsy and panic disorders in Korea. This raises ethical issues in clinical practice, as clonazepam is prescribed off-label for most neuropsychiatric disorders in many other countries as well. The misuse and abuse of clonazepam as a recreational drug have also been commonly reported in global literature. In this review, as a therapeutic drug as the authors aim to highlight the pharmacological aspects, clinical effects, and potential addictive risks of clonazepam use, by reviewing the current literature on clonazepam to increase its clinical use by accurately understanding and identifying its psychopharmacological benefits and characteristics. However, establishing the risk/benefit ratio of clonazepam for use in specific clinical situations is difficult because of the lack of adequate updated data. Therefore, the use of clonazepam needs to be approached from the point of view of personalized drug treatment rather than following fixed guidelines which would not reflect the current real-world clinical practices.

Benzodiazepines have been widely used as anxiolytics, sedatives, hypnotics, anticonvulsants, or central muscle relaxants since the 1960s despite significant adverse effects, the potential for misuse, and consequent overdose. Benzodiazepines exert their pharmacological action by binding to gamma-aminobutyric acid type A (GABA-A) receptors in the brain and facilitateing the inhibitory actions of the neurotransmitter GABA. Recent findings have also elucidated the effects of benzodiazepines on the allosteric modulation of GABA-A receptors, including receptor subtypes and transmembrane proteins, which is a significant step in our understanding of GABA pharmacology. In clinical practice, the use of benzodiazepines to treat psychiatric disorders has been limited due to the challenges associated with the long-term use, namely the risks of abuse, misuse, and overdose, as well as withdrawal effects. Furthermore, the approval of selective serotonin reuptake inhibitors for anxiety disorders has led to their extensive use as a first-line pharmacological option and they have also been promoted in various practice guidelines for the treatment of anxiety disorders. However, although recent systematic reviews and meta-analyses have shown that benzodiazepines are useful and effective drugs for the treatment of various neuropsychiatric disorders, including anxiety, debates over the clinical use of benzodiazepines continue. More than 60 years after the introduction of benzodiazepines in clinical practice, it is necessary to revisit the controversies associated with benzodiazepine use and to update the discussion current approach to practice with thethrough an understanding of the new data on their pharmacological actions and to identify appropriate indications according to the new diagnostic systems of psychiatric disorders through an extensive literature review.

BACKGROUND:
Immunoglobulin A (IgA) nephropathy (IgAN) is one of an important cause of progressive kidney disease and occurs when IgA settles in the kidney resulted in disrupts kidney’s ability to filter waste and excess water.Hydrogels are promising material for medical applications owing to their excellent adaptability and filling ability. Herein, we proposed a hyaluronic acid/gelatin (CHO-HA/Gel-NH2 ) bioactive hydrogel as a cell carrier for therapeutic kidney regeneration in IgAN.
METHODS:
CHO-HA/Gel-NH2 hydrogel was fabricated by Schiff-base reaction without any additional crosslinking agents. The hydrogel concentrations and ratios were evaluated to enhance adequate mechanical properties and biocompatibility for further in vivo study. High serum IgA ddY mice kidneys were treated with human urine-derived renal progenitor cells encapsulated in the hydrogel to investigate the improvement of IgA nephropathy and kidney regeneration.
RESULTS:
The stiffness of the hydrogel was significantly enhanced and could be modulated by altering the concentrations and ratios of hydrogel. CHO-HA/Gel-NH2 at a ratio of 3/7 provided a promising milieu for cells viability and cells proliferation. From week four onwards, there was a significant reduction in blood urea nitrogen and serum creatinine level in Cell/Gel group, as well as well-organized glomeruli and tubules. Moreover, the expression of pro-inflammatory and profibrotic molecules significantly decreased in the Gel/Cell group, whereas anti-inflammatory gene expression was elevated compared to the Cell group.
CONCLUSION
Based on in vivo studies, the renal regenerative ability of the progenitor cells could be further increased by this hydrogel system.

68 Ga-DOTA-peptide PET/CT is a valuable tool for diagnosing neuroendocrine tumors (NET). Various tumors and normal human tissue express the somatostatin receptor (SSTR), warranting attention to positive findings on 68 Ga-DOTA-peptide PET/CT. However, overexpression of SSTR in glomus tumors has not yet been reported. Gastric glomus tumors show many similar features of NET and are often misdiagnosed. We present the case of a 61-year-old male with a glomus tumor who underwent distal gastrectomy under the pretense of an NET grade 1 because the nodule showed focal intense uptake on preoperative 68 Ga-DOTATOC PET/CT.

Electroconvulsive therapy (ECT) is indicated for various mental disorders (e.g., major depressive disorder, schizophrenia, and bipolar disorder) and the behavioral and psychological symptoms of dementia in elderly patients. Furthermore, ECT is a useful first-line treatment in emergency and crisis situations such as suicide risk, violent behavior, catatonia, and food refusal, which are more frequent in elderly patients. ECT is also effective in the treatment of the motor symptoms of neurological disorders, such as Parkinson’s disease and Huntington’s disease. Due to the high risk of various physical diseases, the comorbid physical conditions of elderly patients should be individually controlled to optimize ECT treatment. Compared to young adults, in elderly patients the seizure threshold is higher, the seizure duration is shorter, and the anesthetic dose is lower. On the contrary, the response rate in the elderly is both faster and higher. Considering potential cognitive decline and the prevention of further deterioration of cognitive function in elderly patients, in the absence of significant comorbidities, twice weekly sessions and right unilateral electrode placement with a lower seizure threshold and less cognitive effect are preferred to bilateral electrode placement, which has a high risk of adverse cognitive effects. After an acute course of ECT, continuation and maintenance of ECT, combined with prescription of therapeutic drugs, may prevent possible relapse or recurrence of mental disorders. In conclusion, ECT can be used to treat mental disorders in elderly adults, with safety and effectiveness comparable to that in young adults.
