Acupuncture as an adjuvant therapy for management of treatment-related symptoms in breast cancer patients: Systematic review and meta-analysis (PRISMA-compliant)

BACKGROUND

Although randomized controlled trials have revealed the considerable effectiveness of acupuncture in breast cancer patients, there have been no studies exploring current acupuncture research trends for treatment induced various symptoms in breast cancer patients. This review evaluated the effectiveness of acupuncture for treatment-induced symptoms in breast cancer patients.

METHODS

We performed a systematic review and meta-analysis of the literature regarding acupuncture to treat symptoms associated with breast cancer therapies. The following databases were searched for relevant RCTs published before June 2018: MEDLINE, EMBASE, the Cochrane Library, AMED, CINAHL, OASIS, CNKI, and CiNii.

RESULTS

Among the 19,483 records identified, 835 articles remained after screening titles and abstracts. A total of 19 RCTs were included in this qualitative synthesis. Among the studies, 8 explored climacteric symptoms, 4 explored pain, 2 explored lymphedemas, 2 explored nausea and vomiting and 3 investigated miscellaneous symptoms.explored miscellaneous symptoms due to cancer treatments. Most of the studies reported that acupuncture can alleviate various symptoms of breast cancer treatment. However, there is a lack of evidence as to whether accupuncture can alleviate chemotherapy associated side effects CONCLUSIONS:: Acupuncture may alleviate the treatment-related symptoms of breast cancer; however, further studies are necessary to obtain conclusive evidence of the effectiveness of acupuncture in treating breast cancer.

Additive effects of Artemisia capillaris extract and scopoletin on the relaxation of penile corpus cavernosum smooth muscle

The objective was to investigate the cellular effect and action mechanism of Artemisia capillaris extract (ACE) and its component, scopoletin, on penile corpus cavernosum smooth muscle (PCCSM). In vitro study with PCCSM, the precontracted PCCSM with phenylephrine was treated with ACE or scopoletin. Cyclic nucleotides in the perfusate were measured by radioimmunoassay and expression of protein and mRNA of endothelial nitric oxide synthase (eNOS) and neuronal nitric oxide synthase in the perfused PCCSM were measured by western blot and real-time PCR, respectively. The interaction of ACE or scopoletin with udenafil was also evaluated. ACE and scopoletin exerted a significant and concentration-dependent relaxation in PCCSM. The perfusion with ACE or scopoletin significantly increased cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) and the perfusion with ACE or scopoletin increased the expression of eNOS mRNA and protein. Furthermore, ACE or scopoletin enhanced udenafil-inducing relaxation in PCCSM. ACE and scopoletin relaxed the PCCSM mainly by activating nitric oxide-cGMP system and cAMP pathway and they may be additive therapeutic candidates for ED patients who do not completely respond to udenafil.

EXPRESSION OF P57KIP2 IN GERM CELLS AND LEYDIG CELLS IN HUMAN TESTIS

p57kip2, a KIP family cyclin-dependent kinase (Cdk) inhibitor, blocks the cell cycle by acting on multiple cyclin-Cdk complexes. To investigate the role of p57kip2 in human fertility, the expression of p57kip2 was investigated in testes from normal and obstructive azoospermic male patients who were positive for p57kip2 mRNA. In the seminiferous tubule, strong immunoreactivity of p57kip2 was found in nuclei of early spermatocytes, but not in the spermatogonia. The p57kip2 immunoreactivity in spermatocytes was markedly heterogeneous. Preleptotene spermatocytes showed strong p57kip2 immunoreactivity, but no visible signal was found in late pachytene spermatocytes. Nuclei of the elongating spermatids was also positive for p57kip2 immunoreactivity. Taken together, this suggests that p57kip2 may play a role in the regulation of meiotic progression of early spermatocytes and cell cycle arrest and differentiation of spermatids. p57kip2 immunoreactivity was found in the perinuclear region of the peritubular cells, but not in the Sertoli cells. In Leydig cells, moderate immunoreactivity of p57kip2 was largely found in the cytoplasm, suggesting the noble function of p57kip2 in the differentiation of adult Leydig cells.

Oral testosterone undecanoate (Andriol) supplement therapy improves the quality of life for men with testosterone deficiency

In a single-blind, placebo-controlled study, the effects of a 3-month oral administration of 160 mg/day testosterone undecanoate (Andriol) on the quality of life of men with testosterone deficiency were evaluated. The subjects included ten men with primary hypogonadism and 29 with andropause with sexual dysfunction as the most common problem. The changes in subjective symptoms were evaluated by the PNUH QoL scoring system and the St. Louis University Questionnaire for androgen deficiency in aging males (ADAM). Digital rectal examination (DRE) was performed and serum testosterone, prostate-specific antigen (PSA) and liver profile were monitored. Testosterone undecanoate treatment (n = 33) significantly improved sexual dysfunction and symptom scores of metabolic, cardiopulmonary, musculoskeletal and gastrointestinal functions compared to baseline and to placebo (n = 6). ADAM score also significantly improved after 3 months of treatment. Serum testosterone was significantly increased compared to pretreatment levels only in the testosterone undecanoate group. In the placebo group, no significant changes compared to baseline were found for testosterone levels and QoL questionnaires. No abnormal findings were detected on DRE or laboratory findings in either group. Adverse events, such as gastrointestinal problems and fatigue, were mild and self-limiting. It is concluded that androgen supplement therapy with oral testosterone undecanoate (Andriol) restores the quality of life through improvement of general body functions in men with testosterone deficiency.

An epidemiological study of enuresis in Korean children

OBJECTIVE

To estimate the prevalence of enuresis in children of elementary school age, to evaluate the impact of enuresis on these children and their parents, and to identify the methods and effectiveness of managing enuresis. Subjects and methods A randomly selected cross-sectional study was conducted in one elementary school in each urban ward (nine schools) in Pusan, Korea. The parents of these 12 570 children aged 7-12 years were asked to complete questionnaires which included items about the presence and frequency of enuresis, its perceived impact and management. Enuresis was defined as an episode of wetting occurring at least once per month.

RESULTS

The overall response rate to the questionnaire was 55.8% (girls 28.2%, boys 27.6%). The prevalence of nocturnal, diurnal and combined enuresis was 9.2%, 2.2% and 1.4%, respectively. The overall prevalence of enuresis declined with age from 20.4% at 7 years old to 5.6% at 12 years old; 342 (57.0%) parents and 318 (55. 6%) children were concerned about enuresis. The common self-help strategies were waking the child at night to void (38.1%) and restriction of water intake (25.7%). Of the enuretic children, only 13.7% had consulted a health worker.

CONCLUSION

The prevalence rates for enuresis in Pusan are similar to those reported from European countries. Enuretic children and their parents were moderately concerned about enuresis and the parents primarily used self-management within the family.

Multicenter study of the treatment of erectile dysfunction with transurethral alprostadil (MUSE) in Korea

A Korean multicenter study was conducted to assess the effectiveness of transurethral alprostadil with MUSE in 334 subjects with chronic erectile dysfunction (ED) who were enrolled in 21 clinical centers. Patients with psychogenic impotence comprised about 30% of subjects. Intraurethral alprostadil was titrated in a stepwise fashion in the clinics from 250 to 500 or 1000 mcg based on erectile response and tolerability. The erectile responses were evaluated using an erection assessment scale (score of 1-5). The dose that produced a maximal penile response of score 5 (full rigid erection) or 4 (full tumescence, partial rigidity) was selected for home treatment. Patients who showed partial erection (score of 3) with 1000 mcg were also included in the home-treatment group. In-clinic phase: 198 men (59.3%) had maximal penile responses of score 4 or 5. The rate of maximal responses was not related to patient age, etiology or duration of the ED. A total of 228 (68.3%) men progressed to home treatment. The overall level of comfort of the transurethral alprostadil was rated as uncomfortable or very uncomfortable in 12%. Home phase: During the two-month period of home treatment, 178 (78.1%) men had successful sexual intercourse at least once, and 78.2% of administrations (1976) resulted in successful intercourse. The main causes of drop-out were insufficient erectile response in 27 men (11.8%), adverse reactions (mostly penile or urethral pain) in 7 (3.1%) or both in 7 (3.1%). In conclusion, transurethral alprostadil could be a suitable treatment option for patients with ED regardless of age and etiology of ED. Efficacy in an Asian population (Korea) is comparable to that reported previously in Caucasians.
