Morning breathing exercises prolong lifespan by improving hyperventilation in people living with respiratory cancer.

Disturbance of oxygen-carbon dioxide homeostasis has an impact on cancer. Little is known about the effect of breath training on cancer patients. Here we report our 10-year experience with morning breathing exercises (MBE) in peer-support programs for cancer survivors.We performed a cohort study to investigate long-term surviving patients with lung cancer (LC) and nasopharyngeal cancer (NPC) who practiced MBE on a daily basis. End-tidal breath holding time (ETBHT) after MBE was measured to reflect improvement in alveolar O2 pressure and alveolar CO2 pressure capacity.Patients (female, 57) with a diagnosis of LC (90 patients) and NPC (32 patients) were included. Seventy-six of them were MBE trainees. Average survival years were higher in MBE trainees (9.8 ±â€Š9.5) than nontrainees (3.3 ±â€Š2.8). The 5-year survival rate was 56.6% for MBE trainees and 19.6% for nontrainees (RR = 5.371, 95% CI = 2.271-12.636, P < 0.001). Survival probability of the trainees further increased 17.9-fold for the 10-year survival rate. Compared with the nontrainees, the MBE trainees shows no significant differences in ETBHT (baseline, P = 0.795; 1-2 years, P = 0.301; 3-4 years, P = 0.059) at baseline and within the first 4 years. From the 5th year onwards, significant improvements were observed in ETBHT, aCO2%, PaCO2, and PaO2 (P = 0.028). In total, 18 trainees (40.9%) and 20 nontrainees (74.1%) developed new metastasis (RR = 0.315, 95% CI = 0.108-0.919, P = 0.031).MBE might benefit for the long-term survival in patients with LC and NPC due to improvement in hyperventilation.

Spontaneous remission of membranous glomerulonephritis with successful fetal outcome: A case report and literature review.

Membranous glomerulonephritis (MGN) represents an immunologically mediated disease characterized by deposition of immune complexes in the glomerular subepithelial space. Persistent proteinuria at diagnosis predicts poor prognosis. Pregnancy with MGN is a risk of fetal loss and may worsen maternal renal function.Here, we report a lady with MGN and proteinuria achieved spontaneous remission and successful fetal outcome naive to any medications. The 26-year old woman had 1-year history of persistent proteinuria (5.5-12.56 g/24 hours) and biopsy-proven MGN. Histopathological characteristics included glomerular basement membrane spikes, subepithelial monoclonal IgG immunofluorescence, and diffuse electron dense deposits. She was sticking to a regular morning exercise routine without any medications. After successful delivery of a full-term baby girl, the mother had improved proteinuria (0.56 g/24 hours) and albuminuria (351.96 g/24 hours contrasting 2281.6 g/24 hours before pregnancy). The baby had normal height and body weight at 4 months old.We identified more pregnancies with MGN in 5 case reports and 5 clinical series review articles (7-33 cases included). Spontaneous remission of maternal MGN with good fetal outcome rarely occurred in mothers on immunosuppressive therapy.Mothers naive to immunosuppressive therapy may achieve spontaneous remission of maternal membranous glomerulonephritis and successful fetal outcome. Theoretically, fetus might donate stem cells to heal mother's kidney.

Autoimmunity and dysmetabolism of human acquired immunodeficiency syndrome.

Acquired immunodeficiency syndrome (AIDS) remains ill-defined by lists of symptoms, infections, tumors, and disorders in metabolism and immunity. Low CD4 cell count, severe loss of body weight, pneumocystis pneumonia, and Kaposi's sarcoma are the major disease indicators. Lines of evidence indicate that patients living with AIDS have both immunodeficiency and autoimmunity. Immunodeficiency is attributed to deficits in the skin- and mucosa-defined innate immunity, CD4 T cells and regulatory T cells, presumably relating human immunodeficiency virus (HIV) infection. The autoimmunity in AIDS is evident by: (1) overproduction of autoantibodies, (2) impaired response of CD4 cells and CD8 cells, (3) failure of clinical trials of HIV vaccines, and (4) therapeutic benefits of immunosuppression following solid organ transplantation and bone marrow transplantation in patients at risk of AIDS. Autoantibodies are generated in response to antigens such as debris and molecules de novo released from dead cells, infectious agents, and catabolic events. Disturbances in metabolic homeostasis occur at the interface of immunodeficiency and autoimmunity in the development of AIDS. Optimal treatments favor therapeutics targeting on the regulation of metabolism to restore immune homeostasis.

Insulin-producing acinar cells in adult human pancreas.

OBJECTIVE: The aim of this study was to characterize cells expressing insulin and amylase in adult human pancreas. METHODS: We applied serial section and immunohistochemistry to pancreas samples from 5 adult nondiabetic subjects (2 men and 3 women;mean age, 65.8 years; random plasma glucose level, 5.1 mM). Cells expressing insulin and amylase were captured by immunofluorescence and confocal miscroscopy. RESULTS: We found a widespread occurrence of insulin-producing cells in exocrine acini and amylase-reactive acinar cells in well-formed islets. The insulin-producing cells in exocrine acini predominantly formed single and double cell units though cell clusters, and islands occurred. Acini containing insulin-producing cells outnumbered the islets with a factor of approximately 5. Confocal microscopy and double immunostaining identified acinar A-cells coexpressing both amylase and insulin. CONCLUSIONS: The acinar A-cells represent a distinct category of pancreatic cell populations and might be possible endogenous progenitors of insulin-producing cells in normal and abnormal metabolic homeostasis.
