Benign prostatic hyperplasia (BPH) is a common issue in men older than 40. BPH is accompanied by irritating and obstructive symptoms that sometimes lead to surgery due to lack of recovery. Tamsulosin is an alpha-receptor blocker that is considered a standard treatment for patients. The aim of this study was to investigate the effect of melatonin [a hormone secreted by the pineal gland at night that regulates the sleep-wake cycle] along with standard treatment on improving the BPH urinary symptoms as well as patients’ quality of life due to their urinary problems. This study is a single centre, parallel group randomised, double-blind clinical trial with balanced randomisation. Patients (n = 108) were randomly allocated to one of the two groups. Results show the combination of melatonin and tamsulosin was significantly effective in treating the symptoms of frequency and nocturia in patients with BPH. Authors conclude that their findings can be used to pave the way to improving the symptoms of patients with BPH.
Abstract
PURPOSE to investigate the effect of melatonin along with tamsulosin in improving BPH urinary symptoms. MATERIALS AND METHODS A total of 108 men with BPH symptoms, age of ≥ 50 years, and International Prostate Symptom Score (IPSS) ≥ 8 entered into the parallel group randomized, double-blind clinical trial with balanced randomization. The treatment group received of 3mg melatonin plus 0.4mg tamsulosin and the control group received placebo plus 0.4mg tamsulosin. Patients and physicians were concealed by sealed and opaque envelopes. Symptoms were assessed at baseline and 1 month after treatment. Finally all scores at the initial and end of the study were compared and analyzed using SPSS software. RESULTS This study showed that adding melatonin to the classic treatment of BPH patients with tamsulosin could significantly reduce the likelihood of nocturia by 2.39 times (95% CI: 1.07-5.32, OR = 2.39, p = 0.033) and could also reduce the frequency of urination by 2.59 times (95% CI: 1.15-5.84, OR = 2.59, p = 0.021). There was no statistically significant difference between the two groups in IPSS, intermittency, incomplete emptying, straining, urgency, and weak stream. CONCLUSION Melatonin plus tamsulosin treatment is associated with a significant improvement of nocturia and frequency in patients with benign proststic hyperplasia. However, it is necessary to do more studies.

Plain language summary
The rate of neurodegenerative diseases (ND) is increasing at a concerning rate. The condition is characterized by the progressive decline of neuron function in the brain, eventually leading to cognitive impairment and motorneuron disorders. This process appears to be mediated by the complex interplay of factors. The brain is extremely sensitive to oxidative stress, and oxidative stress and inflammation of the nervous tissue appear to be a common denominator in all neurodegenerative diseases. One of the challenges of ND for prevention as well as treatment and treatment development, is that the initial disease progression usually goes unnoticed, with symptoms only becoming apparent in the more advanced stages when irreversible damage has occurred. Diet quality has a significant impact on brain health and hence can also influence ND development. For example, the Mediterranean diet (MedDiet) has demonstrated many valuable attributes that can reduce ND incidences and improve cognitive function. This review looked at dietary components, natural compounds and medicinal plants that have shown to be beneficial for brain health in ND. The authors discussed the MedDiet followed by a brief review of dietary supplements, including N-acetylcysteine (NAC), phospholipids (Phosphatidylserine, Phosphatidylcholine), Gamma-aminobutyric acid, melatonin, omega-3 fatty acids, neurotropic vitamin B (B1, B6 and B12), S-adenosyl methionine (SAMe), the amino acid tryptophan, magnesium and various polyphenols. Several medicinal plants are reviewed that have demonstrated positive effects on preventing or alleviating neurological diseases. This includes Withania somnifera (Ashwagandha), Baccopa monnieri (Brahmi), Acorus calamus (Calamus) and Hypericum perforatum (St. Johns Wort). The review concluded that many bioactive compounds and plant constituents that can be obtained from a qualitative diet, as well as certain medicinal plants and supplements, can help preserve and promote brain health and prevent the onset of ND. Large clinical trials are needed to assess their suitability for their wider use.
Abstract
A healthy diet shapes a healthy mind. Diet quality has a strong association with brain health. Diet influences the onset and consequences of neurological diseases, and dietary factors may influence mental health at individual and population level. The link between unhealthy diet, impaired cognitive function and neurodegenerative diseases indicates that adopting a healthy diet would ultimately afford prevention and management of neurological diseases and brain aging. Neurodegenerative diseases are of multifactorial origin and result in progressive loss of neuronal function in the brain, leading to cognitive impairment and motoneuron disorders. The so-called Mediterranean diet (MedDiet) with its healthy ingredients rich in antioxidant, anti-inflammatory, immune, neuroprotective, antidepressant, antistress and senolytic activity plays an essential role in the prevention and management of neurological diseases and inhibits cognitive decline in neurodegenerative diseases such as Alzheimer's, Parkinson's and Huntington's diseases. The MedDiet also modulates the gut-brain axis by promoting a diversity of gut microbiota. In view of the importance of diet in neurological diseases management, this review focuses on the dietary components, natural compounds and medicinal plants that have proven beneficial in neurological diseases and for brain health. Among them, polyphenols, omega-3 fatty acids, B vitamins and several ayurvedic herbs have promising beneficial effects.
