Impact of nutrition education programs on complementary feeding: a comparative study among Nigerian men and women

Background: The study assessed how nutrition education programs impact complementary feeding behaviours, with a particular emphasis on understanding the experiences of both men and women in Nigeria. Methods: The study design employed a mixed-methods approach, including a qualitative and quantitative approach, and included 1167 women and 571 men in various places in the north, south, west, and eastern parts of Nigeria. A pre-tested, semi-structured questionnaire about supplemental feeding that was given by interviewers was used to gather the data. Results: The study reveals that most mothers are between the ages of 20 and 40, with a majority of them having completed primary and secondary school. The majority of respondents belong to the medium class, with 42.7% starting their children on cereal too soon at six months. 82.4% supplement their infant's diet with fortified pap, primarily made with infant formula. The majority of mothers use various feeding methods, with 57.1 percent using cups, plates, and spoons, 8.1% using hand feeding, and 8.4% using bottle feeding. Only 5.7% clean their hands after feeding and sanitize their food utensils. The study also shows that traditional gender norms, where men are primarily breadwinners, are being challenged by more progressive views, with 21.2% believing in equal sharing of caregiving responsibilities. Conclusions: The study reveals that Nigeria's supplemental feeding practices are insufficient because of early intake, inadequate follow-up, the prevalence of costly commercial formula and local cereal gruels for meals, and a shift toward shared caregiving responsibilities.

Evaluation of Qualitative and Quantitative Phytochemical Constituents in Saccharum officinarum L. Exposed to Roadside Traffic-Derived Ambient Air Pollution

Saccharum officinarum L. is a useful crop and a member of the Poaceae family that yields sugar molecules with a high concentration. The present study focused on the analysis of qualitative and quantitative phytochemical substances. For the comparative analysis of the crop, we have selected traffic road and non-traffic road sites (control). The qualitative phytochemical substances showed the analysis of protein, carbohydrate, iodine, phenol, tannin, flavonoids, saponin, glycosides, steroid, terpene, and alkaloid, quantitative phytochemical substances of (total phenolic content total mean value 0.03644 ? 0.03240 and total flavonoid content total mean value 0.04772 ? 0.03952). The quality of qualitative and quantitative phytochemical substances in crops growing near traffic roads was reduced. The negative effects of traffic-related air pollution on crop vegetation are clearly shown in this record. Crop vegetation varies between traffic roads and control sites based on analysis of qualitative and quantitative phytochemical substance data.

Comparison of rapid dengue NS1, qualitative ELISA, and quantitative ELISA result

Background: Non-structural glycoprotein-1 (NS1) is a useful biomarker for early diagnosis of dengue fever. NS-1 antigen ELISA can be used for the early diagnosis of dengue fever in the acute stage. Quantitative methods are better for epidemic settings due to high false negative rates in qualitative ELISA. Methods: The study was initiated after approval from the institutional ethics council (IEC/DISS/17118). Study examined 280 patients with dengue symptoms who presented to the hospital's OPDs and IPDs. Patients were tested using qualitative ELISA, and those with Leptospira antibody, malaria, or Chikungunya IgM antibody were excluded. Age, gender, symptoms, comorbidities, total leucocyte count, platelet count, and risk category were all patient-related parameters. Patient-related parameters were recorded, and data was collected using Microsoft excel and analysed statistically. Results: Most patients aged 2-40 with male predominance had fever, chills, and body aches, 243 (86.8%) tested positive for ELISA NS1. Quantitative ELISA test showed a statistically significant correlation with rapid antigen NS1 result (p=0.015). Its AUC was 0.883 (p=0.0001), and its cut-off was (>109.1) with 96.9% sensitivity and 13.64% specificity. The AUC of quantitative ELISA NS1 against qualitative ELISA NS1 was 0.853 which was statistically significant (p<0.0001). At the cut-off >74.34, the test's sensitivity was 92.59% and specificity was 75.68%. Conclusions: Qualitative ELISA NS1 test is better than rapid antigen test for screening due to its higher specificity and similar sensitivity.

Latin American Forensic Odontology: A Scoping Review of its Current Research and the Objective/Subjective Nature of its Studies

SUMMARY: The new paradigm in Forensic Sciences initiated by the entry of genetics (the current standard of legal evidence) and accentuated by recognized wrongful convictions derived from experts today in the eye of criticism, has highlighted the potential for bias and error in forensic disciplines when they depend on human interpretation and subjectivity, which has not been avoided by Forensic Odontology (FO). However, a subjective judgment is not necessarily wrong, so the refinement of processes, the development of standards, and robust research can contribute to the validity of interpretation to increase objectivity. Latin America (LATAM) has its own realities and needs, which have conditioned the priorities and objectives of FO research. A scoping review is presented to systematically map the investigation of LATAM researchers and identify the objective or subjective nature of their assessments. LATAM shows interesting productivity and intentions to adhere to international standards, with Brazil leading this research significantly, followed by Chile and Colombia, among others. However, there is a disproportionate approach in certain lines of research (dental age estimation), and needs to address other quantitative studies, and to improve the visibility of the LATAM FO research.

El nuevo paradigma en ciencias forenses iniciado por la entrada de la genética (el actual estándar de la evidencia jurídica), y acentuado por reconocidas condenas injustas derivadas de pericias hoy en el ojo de la crítica, ha destacado el potencial de sesgo y error que poseen algunas disciplinas forenses cuando dependen de la interpretación humana y la subjetividad, lo cual no ha sido ajeno a la odontología forense (OF). Sin embargo, un juicio subjetivo no necesariamente es erróneo, con lo que el refinamiento de procesos, el desarrollo de estándares y la investigación robusta pueden contribuir a validar esa interpretación para aumentar su objetividad. Latinoamérica (LATAM) posee realidades y necesidades propias que han condicionado las prioridades y objetivos de la investigación en OF. Se presenta una revisión con búsqueda sistemática para mapear sistemáticamente la investigación en OF realizada por investigadores latinoamericanos, así como identificar la naturaleza objetiva o subjetiva de sus evaluaciones. LATAM demuestra una productividad interesante e intenciones de adherirse a estándares internacionales, con Brasil liderando significativamente esta investigación, seguido por Chile y Colombia entre otros. Sin embargo, se observa un enfoque desproporcionado en ciertas líneas de investigación (estimación de edad dental particularmente), y necesidad tanto de abordar otros estudios cuantitativos como de mejorar la visibilidad de la investigación latinoamericana en OF.

MethodThe analysis was performed on an ACQUITY UPLC BEH C18 column（2.1 mm×100 mm， 1.7 μm） with the mobile phase of 0.1% formic acid aqueous solution（A）-acetonitrile（B） for gradient elution（0-3 min， 90%-87%A； 3-6 min， 87%-86%A； 6-9 min， 86%-83%A； 9-11 min， 83%-75%A； 11-18 min， 75%-70%A； 18-19 min， 70%-52%A； 19-22 min， 52%A； 22-25 min， 52%-5%A； 25-27 min， 5%-90%A； 27-30 min， 90%A）. The contents of active ingredients in Erdongtang was detected by electrospray ionization（ESI） and multiple reaction monitoring（MRM） mode under positive and negative ion modes. On this basis， network pharmacology was applied to predict the targets and pathways of Erdongtang exerting anti-insulin resistance effect. ResultThe 20 active ingredients in Erdongtang showed good linear relationships within a certain mass concentration range， and the precision， stability， repeatability and recovery rate were good. The results of determination showed that the ingredients with high content in 15 batches of samples were baicalein（1 259.39-1 635.78 mg·L-1）， baicalin（1 078.37-1 411.52 mg·L-1）， the ingredients with medium content were mangiferin（148.59-217.04 mg·L-1）， timosaponin BⅡ（245.10-604.89 mg·L-1）， quercetin-3-O-glucuronide（89.30-423.26 mg·L-1）， rutin（46.91-1 553.61 mg·L-1）， glycyrrhizic acid（55.97-391.47 mg·L-1）， neomangiferin（37.45-127.03 mg·L-1）， nuciferine（0.89-63.48 mg·L-1）， hyperoside（6.96-136.78 mg·L-1）， liquiritin（30.89-122.78 mg·L-1）， liquiritigenin（26.64-110.67 mg·L-1）， protodioscin（58.57-284.26 mg·L-1）， the ingredients with low content were wogonin（7.16-20.74 mg·L-1）， pseudoprotodioscin（5.49-22.96 mg·L-1）， ginsenoside Rb1（7.31-23.87 mg·L-1）， ginsenoside Rg1（10.78-28.33 mg·L-1）， ginsenoside Re（7.78-24.76 mg·L-1）， ophiopogonin D（2.08-4.29 mg·L-1）， methylophiopogonanone A（0.74-1.67 mg·L-1）. The results of network pharmacology indicated that the mechanism of anti-insulin resistance exerted by Erdongtang might be related to the phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt） signaling pathway. ConclusionThe established UHPLC-QqQ-MS has the advantages of simple sample processing， strong exclusivity and high sensitivity， and can simultaneously determine the contents of the main ingredients from seven herbs in Erdongtang， which can lay the foundation for the development of Erdongtang compound preparations. The results of the network pharmacology can provide a reference for the mechanism study of Erdongtang in the treatment of type 2 diabetes mellitus.

Clinical significance of FOXA3 expression in colorectal cancer / 临床与实验病理学杂志

Purpose To analyze the expression of FOXA3 in colorectal cancer(CRC)and its correlation with clinicopatho-logical features.Methods FOXA3 mRNA expression in 31 CRC cancer tissues and their matched normal tissues was detec-ted by real-time quantitative PCR(RT-qPCR).The protein ex-pression of FOXA3 in 120 CRC cancer tissues was detected by immunohistochemical EnVision two-step method,and the clini-copathologic features such as lymph node metastasis and immu-nohistochemical expression were analyzed.Results The mRNA expression level of FOXA3 in colorectal cancer tissues was sig-nificantly higher than that in paired paracancer tissues(t=2.952,P=0.006 1).FOXA3 protein expression level in color-ectal cancer tissues was not significantly correlated with gender,age,site and size of patients,but significantly correlated with the degree of tissue differentiation(P=0.006)and lymph node metastasis(P=0.002).The degree of differentiation was nega-tively correlated with FOXA3 expression,while lymph node me-tastasis was positively correlated with FOXA3 expression.Sur-vival analysis showed that higher FOXA3 expression was associ-ated with worse overall survival(P＜0.000 1),and FOXA3 was an independent risk factor for prognosis in patients with colorectal cancer.Conclusion This study suggests that FOXA3 may play a promoting role in the occurrence and development of colorectal cancer,and FOXA3 may be a molecular marker for the diagnosis,metastasis and prognosis of colorectal cancer.

Objective To construct reference ranges of cardiac size and morphologic parameters in low-risk fetuses at 28-39 gestational weeks using two-dimensional speckle tracking technique.Methods A prospective collection of 453 low-risk singleton pregnancies with echocardiography at Obstetrics and Gynecology Hospital,Fudan University was used to assess the size(length,width,and area)and morphology(sphericity index,i.e.,the ratio of length to width)of the fetal four-chamber view and two ventricles using two-dimensional speckle tracking technique.Repeated inter-and intra-observer agreement of measurements was assessed using the intraclass correlation coefficients(ICCs).Statistical analysis of cardiac measurement parameters was performed to establish reference ranges of values for cardiac size and morphology in low-risk fetuses.Results The inter-and intra-group ICCs for reproducibility tests of fetal cardiac parameters measurements were 0.691 to 0.980.Fetal four-chamber view and ventricular size increased with gestational week(all P<0.001),the end-diastolic length of the left ventricle was larger than that of the right ventricle,and the end-diastolic diameter was smaller than that of the right ventricle(both P<0.001),while there was no significant difference in the end-diastolic area of the two ventricles(P= 0.050).The spherical index of four-chamber view did not correlate with gestational week(P=0.811).The sphericity index of the basal and intermediate segments of the left ventricle was greater than that of the right ventricle,and the sphericity index of the apical segment was less than that of the right ventricle,the differences were statistically significant(all P<0.01).Conclusion The two-dimensional speckle tracking technique for measuring fetal cardiac parameters has good reproducibility.The reference ranges for cardiac size and morphology in low-risk fetuses developed in this study will be useful for prenatal evaluation of cardiac remodeling.

Objective To determine the quantitative diagnostic criteria of phlegm-stasis interjunction syndrome of metabolic syndrome.Methods Based on the literature research,the Expert Consultation Questionnaire for MS Syndrome of Phlegm-stasis Interjunction based on Analytic Hierarchy Process was developed.Experts were invited to fill out the questionnaire,and the Diagnostic Criteria for MS Syndrome of Phlegm-stasis Interjunction(Draft)was constructed by using the expert group decision algorithm.The patients with MS were prospectively collected,and the diagnostic criteria for phlegm-stasis interjunction syndrome of MS were validated and revised by conditional probability conversion method and maximum likelihood discrimination,and the quantitative diagnostic criteria for phlegm-stasis interjunction syndrome of MS were finally formulated.Results The sensitivity,specificity and accuracy of the established quantitative diagnostic criteria for MS phlegm-stasis interjunction syndrome were 95.7%,84.0%,91.6%,positive likelihood ratio 5.98,negative likelihood ratio 19.46.Conclusion The quantitative diagnostic criteria for MS phlegm-stasis interjunction syndrome established based on literature research,expert consultation and diagnostic tests have good diagnostic efficacy.

Quantitative value of energy spectrum CT material separation technology in nonalcoholic fatty liver / 实用放射学杂志

Objective To investigate the feasibility of energy spectrum CT material separation technology for quantitative evaluation of nonalcoholic fatty liver patients,to compare the accuracy of this method with the conventional liver/spleen CT ratio for grading liver fat content.Methods Sixty patients diagnosed with nonalcoholic fatty liver and 20 healthy volunteers were chosen to undergo liver MR multi-echo(ME)Dixon and energy spectrum CT scans.The proton density fat fraction(PDFF),fat concentration(FC),and liver/spleen CT ratio were then measured for each participant.According to PDFF,nonalcoholic fatty liver patients were divided into mild fatty liver group,moderate fatty liver group,and severe fatty liver group.Results With the increase in PDFF,FC increased and the liver/spleen CT ratio decreased.The difference between FC groups in normal,mild,moderate and severe fatty liver groups was statistically significant(P<0.05),while the difference between the liver/spleen CT ratio of normal group and mild fatty liver group was not statistically significant(P>0.05).The receiver operating characteristic(ROC)curve analysis showed that when the critical value of FC was 351.19 mg/mL,the sensitivity,specificity and area under the curve for normal group and fatty liver group were 0.95,0.1 and 0.99,respectively.Conclusion The energy spectrum CT material separation technology has a good correlation between the fat content measured by the MR ME Dixon,which is superior to the fat content measured by the liver/spleen CT ratio.For patients with nonalcoholic fatty liver,FC in energy spectrum CT has high accuracy in differentiating normal and mild fatty liver.
