Telepsychiatry versus face-to-face treatment: systematic review and meta-analysis of randomised controlled trials.

BACKGROUND: The COVID-19 pandemic has transformed healthcare significantly and telepsychiatry is now the primary means of treatment in some countries. AIMS: To compare the efficacy of telepsychiatry and face-to-face treatment. METHOD: A comprehensive meta-analysis comparing telepsychiatry with face-to-face treatment for psychiatric disorders. The primary outcome was the mean change in the standard symptom scale scores used for each psychiatric disorder. Secondary outcomes included all meta-analysable outcomes, such as all-cause discontinuation and safety/tolerability. RESULTS: We identified 32 studies (n = 3592 participants) across 11 mental illnesses. Disease-specific analyses showed that telepsychiatry was superior to face-to-face treatment regarding symptom improvement for depressive disorders (k = 6 studies, n = 561; standardised mean difference s.m.d. = -0.325, 95% CI -0.640 to -0.011, P = 0.043), whereas face-to-face treatment was superior to telepsychiatry for eating disorder (k = 1, n = 128; s.m.d. = 0.368, 95% CI 0.018-0.717, P = 0.039). No significant difference was seen between telepsychiatry and face-to-face treatment when all the studies/diagnoses were combined (k = 26, n = 2290; P = 0.248). Telepsychiatry had significantly fewer all-cause discontinuations than face-to-face treatment for mild cognitive impairment (k = 1, n = 61; risk ratio RR = 0.552, 95% CI 0.312-0.975, P = 0.040), whereas the opposite was seen for substance misuse (k = 1, n = 85; RR = 37.41, 95% CI 2.356-594.1, P = 0.010). No significant difference regarding all-cause discontinuation was seen between telepsychiatry and face-to-face treatment when all the studies/diagnoses were combined (k = 27, n = 3341; P = 0.564). CONCLUSIONS: Telepsychiatry achieved a symptom improvement effect for various psychiatric disorders similar to that of face-to-face treatment. However, some superiorities/inferiorities were seen across a few specific psychiatric disorders, suggesting that its efficacy may vary according to disease type.

Cloning and sequencing of cDNA and genomic DNA encoding serine carboxypeptidase of Fusarium moniliforme that was copurified with phosphatase.

A previous study [Yoshida, H. et al., J. Biochem., 140, 813-823 (2006)] revealed that a protein of unknown nature was copurified with PDM phosphatase of Fusarium moniliforme. In this study, the identity of this protein was investigated. The results of homology search for the tryptic peptides derived from the purified preparation of PDM phosphatase strongly suggested that it might be serine carboxypeptidase. In fact, carboxypeptidase activity was demonstrated in the preparation and partial separation of carboxypeptidase from PDM phosphatase was achieved by gel filtration high-performance liquid chromatography. Cloning and sequencing of the full-length cDNA encoding the carboxypeptidase was successfully conducted. The cDNA possessed an open reading frame for a protein of 575 amino acid residues with a molecular mass of 64,650 Da, which was highly homologous to certain fungal serine carboxypeptidases. Comparison of the deduced amino acid sequence with the N-terminal sequence of the separated carboxypeptidase revealed that the mature enzyme starts at serine 56 of the precursor and has a molecular mass of 58,487 Da. Cloning and sequencing of the genomic DNA corresponding to the cDNA demonstrated that the gene of carboxypeptidase consists of four exons. A limited number of close homologs of F. moniliforme carboxypeptidase were detected among fungi by homology search and their evolutionary relationship was discussed.

Cloning and sequencing of cDNA and genomic DNA encoding PDM phosphatase of Fusarium moniliforme.

PDM phosphatase was purified approximately 500-fold through six steps from the extract of dried powder of the culture filtrate of Fusarium moniliforme. The purified preparation appeared homogeneous on SDS-PAGE although the protein band was broad. Amino acid sequence information was collected on tryptic peptides from this preparation. cDNA cloning was carried out based on the information. A full-length cDNA was obtained and sequenced. The sequence had an open reading frame of 651 amino acid residues with a molecular mass of 69,988 Da. Cloning and sequencing of the genomic DNA corresponding to the cDNA was also conducted. The deduced amino acid sequence could account for many but not all of the tryptic peptides, suggesting presence of contaminant protein(s). SDS-PAGE analysis after chemical deglycosylation showed two proteins with molecular masses of 58 and 68 kDa. This implied that the 58 kDa protein had been copurified with PDM phosphatase. Homology search showed that PDM phosphatase belongs to the purple acid phosphatase family, which is widely distributed in the biosphere. Sequence data of fungal purple acid phosphatases were collected from the database. Processing of the data revealed presence of two types, whose evolutionary relationships were discussed.

Anticancer Effect of Ginger Extract against Pancreatic Cancer Cells Mainly through Reactive Oxygen Species-Mediated Autotic Cell Death.

The extract of ginger (Zingiber officinale Roscoe) and its major pungent components, [6]-shogaol and [6]-gingerol, have been shown to have an anti-proliferative effect on several tumor cell lines. However, the anticancer activity of the ginger extract in pancreatic cancer is poorly understood. Here, we demonstrate that the ethanol-extracted materials of ginger suppressed cell cycle progression and consequently induced the death of human pancreatic cancer cell lines, including Panc-1 cells. The underlying mechanism entailed autosis, a recently characterized form of cell death, but not apoptosis or necroptosis. The extract markedly increased the LC3-II/LC3-I ratio, decreased SQSTM1/p62 protein, and enhanced vacuolization of the cytoplasm in Panc-1 cells. It activated AMPK, a positive regulator of autophagy, and inhibited mTOR, a negative autophagic regulator. The autophagy inhibitors 3-methyladenine and chloroquine partially prevented cell death. Morphologically, however, focal membrane rupture, nuclear shrinkage, focal swelling of the perinuclear space and electron dense mitochondria, which are unique morphological features of autosis, were observed. The extract enhanced reactive oxygen species (ROS) generation, and the antioxidant N-acetylcystein attenuated cell death. Our study revealed that daily intraperitoneal administration of the extract significantly prolonged survival (P = 0.0069) in a peritoneal dissemination model and suppressed tumor growth in an orthotopic model of pancreatic cancer (P < 0.01) without serious adverse effects. Although [6]-shogaol but not [6]-gingerol showed similar effects, chromatographic analyses suggested the presence of other constituent(s) as active substances. Together, these results show that ginger extract has potent anticancer activity against pancreatic cancer cells by inducing ROS-mediated autosis and warrants further investigation in order to develop an efficacious candidate drug.

Controlling photochromism between fluoroalkyl end-capped oligomer/polyaniline and N,N'-diphenyl-1,4-phenylenediamine nanocomposites induced by UV-light-responsive titanium oxide nanoparticles.

Colloidal stable fluoroalkyl end-capped 2-(methacryloyloxy)ethanesulfonic acid oligomer [R(F)-(MES)(n)-R(F)]/polyaniline[PAn]/TiO(2) nanocomposites and R(F)-(MES)(n)-R(F)/An-dimer (An-dimer: N,N'-diphenyl-1,4-phenylenediamine)/TiO(2) nanocomposites were prepared by the interactions of TiO(2) nanoparticles with R(F)-(MES)(n)-R(F)/PAn nanocomposites or R(F)-(MES)(n)-R(F)/An-dimer nanocomposites, which were prepared by the composite reaction of R(F)-(MES)(n)-R(F) oligomer with PAn or An-dimer. These two types of fluorinated TiO(2) nanocomposites can exhibit quite different photochromic behaviors: R(F)-(MES)(n)-R(F)/PAn/TiO(2) nanocomposites can exhibit a reversible wavelength change for polaron absorptions around 760-820 nm by alternation of UV irradiation and storage in the dark; in contrast, R(F)-(MES)(n)-R(F)/An-dimer/TiO(2) nanocomposites can exhibit a reversible color change from blue to colorless (a reversible absorbance change) by the similar treatment.
