BACKGROUND

High-risk areas in the Philippines still experience a high prevalence of undernutrition. The efforts of the governments are not enough to reach those who are in need; hence, the presence of Civil Society Organizations (CSOs) is crucial. One CSO has implemented health and nutrition technical programs to increase the number of well-fed children in four selected areas in the Philippines.

This study aims to shed light on the differences in the nutritional status of the children when they are characterized according to their sociodemographic and economic covariates.

An analytical cross-sectional design was used to survey 692 households, including 764 children aged 0–5 years old. Descriptive analysis and the Chi-Square test of difference were used to answer the objectives.

The study results show that no significant differences were observed when the nutritional status of the children was characterized according to the sociodemographic of the caregiver, food consumption score (FCS) and food security status, water, hygiene and sanitation (WASH) practices, and economic indicators, except weight-for-height and marital status of caregivers, and weight-for-age and livelihood and economic support received by their caregivers (P = 0.02).

The majority of children, regardless of their nutritional status, share the same experience and resources in terms of sociodemographics of caregivers, FCS and food security status, WASH practices, and economic indicators. CSO can boost the impact of their health and nutrition interventions by harmonizing their efforts with government programs, leading to better-targeted and more efficient outcomes.

Objective In this study,we aimed to use network pharmacology techniques to predict the key targets of a prescription of Ziziphi spinosae semen formula(ZSSF)compound for depression,and to verify its mechanism of action using a zebrafish model of rifampicin-induced depression.Methods The drug targets of ZSSF were retrieved from the TCMSP database,and the target names were corrected using the UniProt database.Depression-related targets were identified using the GeneCards,OMIM,and NCBI databases.Protein-protein interaction information for the shared targets was predicted using the STRING database.The collected data were then analyzed using the Metascape database to determine GO and KEGG pathway enrichment,and the result were visualized using microbiotics.Behavioral experiments and reverse-transcription quantitative PCR experiments were conducted to verify the therapeutic effects of ZSSF on a zebrafish depression model induced by risperdal.Results 188 targets were screened to find the interactions between depression and ZSSF.The protein-protein interaction result showed that ZSSF primarily targeted TNF-α,IL-2,IL-6,IL-1β,and IL-10 to produce its antidepressant effect.KEGG pathway enrichment analysis revealed that ZSSF exerted its effects on depression through various signaling pathways,including the TNF,PI3K-Akt,and cGMP-PKG signaling pathways.The result of the animal experiments showed that the treatment groups given high,medium,and low doses of ZSSF exhibited significant improvements in movement distance under acoustic and light stimulation compared with the model group(P＜0.05).The speed of movement of the treatment groups was also significantly faster(P＜0.01).Additionally,the mRNA expression levels of TNF-α,IL-2,IL-6,IL-1β,and IL-10 were up-regulated in the brain tissues of zebrafish in the high-,medium-,and low-dosage groups of ZSSF compared those in the model group(P＜0.001).Conclusions ZSSF exerts its antidepressant effect through multiple components and targets,and its antidepressant effects may be associated with its inhibition of inflammatory factors.

Objective To investigate the effects of alcoholic extract of Hemerocallis citrina Baroni on the depressive-like behaviors in zebrafish larvae(Danio rerio)induced by reserpine.Methods Zebrafish larvae were divided into various groups:control(Con)group,reserpine group,fluoxetine group,H.citrina alcohol extract(HCE)low dose group(1.5 mg/L),HCE medium dose group(3 mg/L),and HCE high dose group(4.5 mg/L).Depressive-like behaviors were analyzed using sound and light stimulation.Real-time PCR was used to investigate the effects of HCE on depression related astrocyte markers(GFAP,C3,C4B,EMP-1,S100α-10)and the neurotrophic factor BDNF and its receptor genes(P75,TrkB).Results In comparison to the control group,the model group demonstrated significantly shorter movement distance and reduced movement time under sound and light stimulation(P＜0.05,P＜0.001,P＜0.0001).Following the administration of HCE,zebrafish larvae exhibited significantly heightened sensitivity to light and sound stimulation compared to the model group(P＜0.05,P＜0.0001).Astrocyte marker genes were up-regulated in the model group zebrafish brains compared to the control group(P＜0.0001).However,when the model group was administered HCE,the expression of astrocyte markers was significantly down-regulated compared to the model group(P＜0.0001).Neurotrophic factor and its receptor genes(BDNF,P75,TrkB)were down-regulated in zebrafish brains in the model group compared to those in the control group(P＜0.0001).However,in the group administered HCE,the expression of BDNF,P75,and TrkB was significantly up-regulated compared to that in the model group(P＜0.01,P＜0.0001).These findings suggest that HCE suppressed the inflammatory responses caused by astrocyte activation and promoted the production of neurotrophic factors and their receptor genes,thereby exerting an ameliorative effect on depression.Conclusions Alcoholic extracts of H.citrina can ameliorate the depression-like behavioral changes induced by reserpine in zebrafish larvae.They reduce the expression of astrocyte markers in the zebrafish brain and promote the production of neurotrophic factors and their receptor genes,playing an antidepressant role.

Objective To examine the hypoglycemic effect of Chinese yam polysaccharide on the 3T3-L1 insulin resistance cell model.Methods IR-3T3-L1 adipocytes were randomly divided into control group(Con),model group(DEX),metformin group(Met,positive drug group)and CYPS group(0.05,0.15,0.45 mg/mL).After the creation of the IR-3T3-L1 cell model by dexamethasone(DEX)(1 μmol/L)stimulation,Chinese yam polysaccharide treatment was applied.Glucose intake and the levels of TC,TG,LDL-C,HDL-C,GSH-Px,MDA,HK,and PK were then measured.AMPK-PI3K/Akt signaling pathway-associated gene expression was identified using qRT-PCR.Results The glucose consumption of IR-3T3-L1 cells was considerably decreased after 48 hours of treatment with 1 μmol/L DEX compared to that of the Con group(P＜0.01),and the reduction persisted for 60 hours.0.05,0.15,0.45 mg/mL CYPS treatment significantly increased glucose consumption(P＜0.01),HK,PK,GSH-Px enzyme activities(P＜0.01),HDL-C content(P＜0.01),and decreased MDA enzyme activity(P＜0.01),T-CHO,TG,LDL-C content(P＜0.01)in IR-3T3-L1 cells.01).Additionally,CYPS administration dramatically decreased PI3K,Akt,GLUT-4,AMPK,IRS-2,PPARa,and adiponectin mRNA expression levels(P＜0.05)and reduced IRS-1,GSK-3β,ACC,and FAS mRNA expression levels(P＜0.01).Conclusions In IR-3T3-L1 cells,CYPS can reduce oxidative stress,control lipid metabolism disorders,and enhance DEX-induced glucose intake.AMPK-PI3K/Akt signaling pathway-associated genes may be connected to the process.

Purpose: Recent research has highlighted the mechanotransducer PIEZO2 as a crucial factor in lower urinary tract function, demonstrating associations with bladder compliance (BC), bladder wall thickening, and elevated bladder pressure. We explored the hypothesis that PIEZO2 expression may be associated with lower urinary tract dysfunction in men with bladder outlet obstruction (BOO) due to benign prostatic hyperplasia (BPH). Methods: The study included a consecutive series of patients undergoing open prostatectomy for BPH at our hospital between September 2014 and January 2016. All participants underwent comprehensive preoperative evaluations, including urodynamic assessments. During prostatectomy, a full-thickness fragment of the bladder wall was obtained for subsequent PIEZO2 gene expression analysis. Cadaveric organ donors served as the control group. Results: PIEZO2 expression was downregulated in the detrusor muscle of men with BPH compared to the control group. Among patients with BPH, those experiencing urinary retention and requiring an indwelling catheter exhibited significantly lower PIEZO2 messenger RNA (mRNA) expression than patients capable of spontaneous voiding. PIEZO2 mRNA expression was similar in men with and without detrusor overactivity. Additionally, a positive correlation was found between PIEZO2 mRNA expression levels and BC. Conclusions Our findings indicate that PIEZO2 is downregulated in the detrusor muscle of men with BPH, particularly in those experiencing urinary retention and those with reduced BC. These results suggest a potential role for PIEZO2 in BOOinduced bladder dysfunction. Further research is required to clarify the role of PIEZO mechanotransducers in the bladder and to explore their therapeutic implications.

Objectives: This study verified the possibility of cementing fiberglass-reinforced posts using a flowable bulk-fill composite (BF), comparing its push-out bond strength and microhardness with these properties of 3 luting materials. Materials and Methods: Sixty endodontically treated bovine roots were used. Posts were cemented using conventional dual-cured cement (CC); self-adhesive cement (SA); dual-cured composite (RC); and BF. Push-out bond strength (n = 10) and microhardness (n = 5) tests were performed after 1 week and 4 months of storage. Two-way repeated measures analysis of variance (ANOVA), 1-way ANOVA, t-test, and Tukey post-hoc tests were applied for the pushout bond strength and microhardness results; and Pearson correlation test was applied to verify the correlation between push-out bond strength and microhardness results (α = 0.05). Results: BF presented higher push-out bond strength than CC and SA in the cervical third before aging (p < 0.01). No differences were found between push-out bond strength before and after aging for all the luting materials (p = 0.84). Regarding hardness, only SA presented higher values measured before than after aging (p < 0.01). RC and BF did not present 80% of the maximum hardness at the apical regions. A strong positive correlation was found between the luting materials' push-out bond strength and microhardness (p < 0.01, R 2 = 0.7912). Conclusions The BF presented comparable or higher push-out bond strength and microhardness than the luting materials, which indicates that it could be used for cementing resin posts in situations where adequate light curing is possible.

Objectives: The present study evaluated the pulp response of human mandibular incisors subjected to in-office dental bleaching using gels with medium or high concentrations of hydrogen peroxide (HP). Materials and Methods: The following groups were compared: 35% HP (HP35; n = 5) or 20% HP (HP20; n = 4). In the control group (CONT; n = 2), no dental bleaching was performed. The color change (CC) was registered at baseline and after 2 days using the Vita Classical shade guide. Tooth sensitivity (TS) was also recorded for 2 days post-bleaching. The teeth were extracted 2 days after the clinical procedure and subjected to histological analysis. The CC and overall scores for histological evaluation were evaluated by the Kruskal-Wallis and Mann-Whitney tests. The percentage of patients with TS was evaluated by the Fisher exact test (α = 0.05). Results: The CC and TS of the HP35 group were significantly higher than those of the CONT group (p < 0.05) and the HP20 group showed an intermediate response, without significant differences from either the HP35 or CONT group (p > 0.05). In both experimental groups, the coronal pulp tissue exhibited partial necrosis associated with tertiary dentin deposition. Overall, the subjacent pulp tissue exhibited a mild inflammatory response. Conclusions In-office bleaching therapies using bleaching gels with 20% or 35% HP caused similar pulp damage to the mandibular incisors, characterized by partial necrosis, tertiary dentin deposition, and mild inflammation.

BACKGROUND: The prevalence of heart failure (HF) increases with age, and it is one of the leading causes of hospitalization and death in older patients. However, there are little data on in-hospital mortality in patients with HF ≥ 75 years in Spain. METHODS: A retrospective analysis of the Spanish Minimum Basic Data Set was performed, including all HF episodes discharged from public hospitals in Spain between 2016 and 2019. Coding was performed using the International Classification of Diseases, 10^th Revision. Patients ≥ 75 years with HF as the principal diagnosis were selected. We calculated: (1) the crude in-hospital mortality rate and its distribution according to age and sex; (2) the risk-standardized in-hospital mortality ratio; and (3) the association between in-hospital mortality and the availability of an intensive cardiac care unit (ICCU) in the hospital. RESULTS: We included 354,792 HF episodes of patients over 75 years. The mean age was 85.2 ± 5.5 years, and 59.2% of patients were women. The most frequent comorbidities were renal failure (46.1%), diabetes mellitus (35.5%), valvular disease (33.9%), cardiorespiratory failure (29.8%), and hypertension (26.9%). In-hospital mortality was 12.7%, and increased with age [odds ratio (OR) = 1.07, 95% CI: 1.07-1.07, P < 0.001] and was lower in women (OR = 0.96, 95% CI: 0.92-0.97, P < 0.001). The main predictors of mortality were the presence of cardiogenic shock (OR = 19.5, 95% CI: 16.8-22.7, P < 0.001), stroke (OR = 3.5, 95% CI: 3.0-4.0, P < 0.001) and advanced cancer (OR = 2.6, 95% CI: 2.5-2.8, P < 0.001). In hospitals with ICCU, the in-hospital risk-adjusted mortality tended to be lower (OR = 0.85, 95% CI: 0.72-1.00, P = 0.053). CONCLUSIONS In-hospital mortality in patients with HF ≥ 75 years between 2016 and 2019 was 12.7%, higher in males and elderly patients. The main predictors of mortality were cardiogenic shock, stroke, and advanced cancer. There was a trend toward lower mortality in centers with an ICCU.

BACKGROUND: Instrumented posterior cervical spine surgery (IPCSS) can be conducted using screws inserted through the pedicles of the vertebra. A safe IPCSS method uses 3D-printing to produce templates that will serve as drill guides for screw placement. OBJECTIVES: This study describes the generation of 3D-printed drill guides using low-cost general purpose 3D modeling software and the comparison of screw insertion accuracy scores against the traditional landmark method and guides created using commercial grade software. METHODS: Twenty-five (25) subaxial pedicles of five cadaveric spines were selected and scanned using computed tomography (CT). A digital reconstruction of the five cadaveric spines were created based on the CT DICOM data. A low-cost 3D modeling software, Rhinoceros 3D, was utilized for trajectory planning and generation of a patientspecific drill template using the digital reconstruction. The templates were then fabricated in ABS plastic using a fused deposition modeling (FDM) 3D printer. Insertion of cervical pedicle screws on the cadaveric spines was done by an orthopedic resident using the 3D printed guides. Postoperative CT scans were obtained, and placement accuracy of the screws were scored by two assessors utilizing a four-point rating system. Screws in correct placement were scored Grade 0 while misplaced screws with neurovascular damage were given a score of Grade 3. RESULTS: Accuracy scores for the 3D-printed drill guides were 52% for assessor 1 and 44% for assessor 2. For assessor 1, screw placement in C3, C6, and C7 received the highest scores. For assessor 2, the highest scores were achieved in C3 and C7. The hybrid method of Bundoc et al. achieved scores of 94% while 3D printed guides utilizing commercial software like Materialise Mimics, Geomagic Freeform, or UG Imageware achieved scores of 80-100%. The traditional landmark method had scores ranging from 12% to 94% depending on the skill of the surgeon. CONCLUSION Commercial medical 3D image-based engineering software has high acquisition costs that might be beyond the reach of most institutions. A sub-$1000 general purpose 3D modeling software can be used to create drill templates. Several factors were identified in the design and fabrication of the template that can be addressed to increase accuracy. Trajectory planning can also be improved by automating the process. The researchers recommend further studies in these areas specially in the context of developing 3D printing as a support service for surgical operations in the Philippines.
