Surgical correction of Tessier cleft no. 7: A single center 18-year experience.

INTRODUCTION: Tessier cleft 7 are rare craniofacial clefts. Live-birth incidence varies from 1/80,000 to 1/300,000, with the incidence of 1 in 120 craniofacial clefts among Asians. Its clinical presentation varies widely in severity, thus, complicating diagnosis and contributing to the lack of consensus regarding its surgical management. The aim of this study is to describe clinical findings, types of Tessier cleft 7 soft tissue repair, and its outcomes in Kuala Lumpur Hospital. METHODS: This retrospective study reviewed records of children operated from January 2001 to July 2019. Data regarding concurrent congenital anomalies, complications, type of surgery, etc., were collected from outpatient records, operative notes, and clinical photographs. RESULTS: Twenty-eight children were treated, and 33 clefts (5 bilateral) were repaired. The male-to-female ratio was 1.3:1 (16 males and 12 females). Twenty-three patients had unilateral clefts (82.14%), with 14 right (60.86%) and 8 left (34.78%). Bilateral clefts were less common (17.86%). Twenty-three patients (82.14%) were Malay, 3 (10.71%) Chinese, 1 (3.57%) Indian, and 1 (3.57%) Cambodian. Eleven medical records were untraceable (discontinued due to duration of inactivity). There were 10 straight-line repairs, 5 Z-plasties, and 1 W-plasty performed; 3 cases did not detail the type of repair. One child required scar revision, and 1 had hypertrophic scarring requiring corticosteroid injection-no disturbances in speech or oral incompetency while eating were reported. Duration of follow-up ranged from 3 to 14 years. CONCLUSION: Our center has a higher rate of Tessier cleft 7 attendance. Straight-line cutaneous repairs combined with inferior vermilion mucosal flap can be used with low rates of complication and revision surgery.

Prediction of the Endocrine disruption profile of fluorinated biphenyls and analogues: An in silico study.

Fluorinated biphenyls and their analogues (FBAs) are considered new persistent organic pollutants, but their endocrine-disrupting effects are still unknown. To fill this gap, the binding probability of 44 FBAs to different nuclear hormone receptors (NHRs) was predicted using Endocrine Disruptome. And molecular similarity and network toxicology analysis were used to strengthen the docking screening. The docking results showed that FBAs could have high binding potential for various NHRs, such as estrogen receptors ß antagonism (ERß an), liver X receptors α (LXRα), estrogen receptors α (ERα), and liver X receptors ß (LXRß). The similarity analysis found that the degree of overlap of the NHR repertoire was related to the Tanimoto coefficient of FBAs. Network toxicology verified a part of docking screening results and identified endocrine-disrupting pathways worthy of attention. This study found out potential endocrine-disrupting FBAs and their vulnerable, and developed a workflow that would leverage in silico approaches including molecular docking, similarity, and network toxicology for risk prioritization of potential endocrine-disrupting compounds.

Changes in Spinal Alignment of Women Who Underwent Unilateral Mastectomy with Immediate Autologous Breast Reconstruction Compared To Mastectomy without Breast Reconstruction.

INTRODUCTION: The impact of breast reconstruction on spinal alignment is not well studied, especially in immediate autologous breast reconstruction. Studies on body posture have shown greater asymmetry among those without reconstruction. This study compared the changes in spinal alignment pre- and post-operatively among women who underwent unilateral mastectomy without reconstruction (MA) versus immediate autologous breast reconstruction (IABR). METHODS: A cross sectional, retrospective study analysed MA and IABRs performed from January 2007 to December 2017 and their pre- and post-operative anterior chest radiographs. The change in Cobb's angle (degrees) less than 1 year, 1 to 2 years, more than 2 years post-operatively were analysed using GE Healthcare Centricity Picture Archive and Communications Systems. RESULTS: 537 patients underwent mastectomy; 76 fulfilled the inclusion criteria (36 IABR, 40 MA). No significant difference existed between mean pre- and post-operative Cobb's angle change across all 3 groups, less than 1 year (MA 3.57±3.84, IABR 3.316±2.72, p=0.81), 1 to 2 years (MA 1.84±4.81, IABR -2.68±3.21, p=0.577) and more than 2 years post-operatively (MA -1.14±5.30, IABR -0.94±5.10, p=0.898). However raw data indicated IABR improved spinal alignment in the short and intermediate period post-operatively. Among IABR, free flap breast reconstruction improved spinal alignment compared to pedicled flaps [free flaps: 2.21±3.28, pedicled flaps: 0.01±3.67 (p=0.027)]. CONCLUSION: IABR has a positive impact on spinal alignment in early and intermediate post-operative period compared to MA, especially in women with larger breast volume. Physical benefits of IABR should be highlighted to improve patient's access to breast reconstruction globally.

Dietary Zinc Intake Affects the Association Between Dietary Vitamin A and Depression: A Cross-Sectional Study.

Introduction: Dietary vitamin A concentrations correlate with depression. Zinc has been reported to be associated with lower depression. In addition, zinc is an important cofactor in the activation of vitamin A. However, there are few studies investigating relationships between of dietary zinc intake, dietary vitamin A intake and depression. Materials and Methods: The data for this study came from the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2018 and involved 70,190 participants. We stratified participants by recommended dietary zinc intake (recommended dietary zinc intake for women: 8 mg/day, recommended dietary zinc intake for men: 11 mg/day). We further assessed the association between vitamin A and depression in participants with low and high zinc intake (interaction test) using univariate logistic regression of intake participants. Result: In the female population we grouped the population into low and high zinc intake groups using the recommended dietary zinc intake of 8 (mg/day), with an increase in total vitamin A, the risk of depression was significantly lower in the low zinc intake group (OR: 0.85 95 CI: 0.76-0.96), while the risk of depression was increased in the high zinc intake group (OR: 1.05 95 CI: 0.95 to 1.17). Thus, in the female population, there was a significant interaction between insufficient vitamin an intake and depression (interaction likelihood ratio test of p = 0.011). In the male population we grouped the population by the recommended dietary zinc intake of 11(mg/day). Again, the population was divided into two groups with low and high zinc intake, however we did not find significant results for the interaction (p = 0.743 for the interaction likelihood ratio test). Conclusion: Our findings suggest that zinc intake may influence the relationship between dietary vitamin A and depression. Of course, our findings require further randomized controlled trials to enhance the credibility.

Investigation of the efficiency and stability of a novel visualized lattice CO2 laser-based gynecological therapeutic apparatus for the treatment of cervical diseases in rhesus monkeys.

The fractional CO2 laser is a type of ablative laser. In this study, a novel fractional CO2 laser therapeutic apparatus was developed for cervical diseases. To compare the depth and diameter of penetration as well as the stability of a novel laser against a control laser emitting at the same wavelength, we tested this using a rhesus monkey model. The cervixes of rhesus monkeys were irradiated with the novel CO2 laser. The effects of irradiation were assessed by measuring the depths and diameters of the holes created by the laser. In addition, the depths and diameters of the holes were compared between the novel CO2 laser-based gynecological therapeutic apparatus and the conventional CO2 laser-based therapeutic apparatus. When operated under the single spot mode and at the same energy level, the novel CO2 laser-based gynecological therapeutic apparatus created holes that could reach the greater depth. In addition, the laser spot size of the new apparatus was more constant. Moreover, there were no significant differences in the side effects between the new apparatus and the conventional apparatus. The results indicate that the novel CO2 laser-based gynecological therapeutic apparatus exhibits better stability in comparison to the conventional CO2 laser-based therapeutic apparatus.

A population-based predictive model to identify patients with signet ring cell carcinoma of the stomach who are most suitable for primary tumor resection.

BACKGROUND: Though the survival benefit of primary tumor operation for patients with signet ring cell carcinoma of the stomach is known, the specific characteristics of those patients who would profit from the operation are yet to be determined. To this end, a predictive model was developed to identify the conjecture that the survival profit from primary tumor operation would only be obtained by patients. METHOD: The clinical data of the patients with signet ring cell carcinoma of the stomach were obtained from the Surveillance, Epidemiology, and End Results database, and then divided into operation and no-operation groups based on whether the patients underwent the primary tumor operation. To remove the confounding factors, propensity score matching was employed, and it was hypothesized that the patients who had been operated on and lived a longer life than the median cancer-specific survival time of those who hadn't must have profited from the surgery. To discuss the independent factors of cancer-specific survival time in the beneficial group and the non-beneficial group, the Cox model was used, and based on the various vital predictive factors, a nomogram was drawn using logistic regression. RESULT: The number of eligible patients was 12,484, with 43.9% (5483) of them having received surgery. After employing propensity score matching, the cancer-specific survival time of the operation group was found to be apparently longer (median: 21 vs. 5 months; p < 0.001) than the no-operation group. In the operation group, 4757 (86.7%) of the patients lived longer than five months (beneficial group). The six indexes (beneficial and non-beneficial group) included gender, age, Tumor Node Metastasis stage, histologic type, differentiation grade, and tumor position, and were used as predictors to draw the nomogram. The nomogram was used to divide the patients who had taken operations into two groups: the beneficial operation group and the non-beneficial operation group. The beneficial operation group, it was found, survived longer than the non-beneficial operation group (median cancer-specific survival time: 28 vs. 3 months, p < 0.001). Moreover, there was we could tell little difference in survival between the two groups (median cancer-specific survival time: 3 vs. 5 months). CONCLUSIONS: The predictive model created to select suitable candidates for surgical treatment from patients with signet ring carcinoma of the stomach could be adopted to identify certain patients benefiting from the primary tumor operation.

Nutritional status of under-five children from urban low-income families in Xiangtan and Jilin in China.

There have been many studies on the nutrition and the growth status of children from rural and remote western regions of China, whereas researches on children from urban low-income families are scarce. This study aimed to investigate the growth and nutritional status of children under five years of age from urban low-income families in China. There were 169 children aged 25-60 months recruited from Xiangtan and Jilin, two cities with a population of 2.81 million and 4.26 million respectively, in China in this cluster cross-sectional study. Data were collected on demographic and socioeconomic characteristics, the feeding practices and the incidence of anemia and diarrhea. The results showed that the prevalence of low birth weight and macrosomia was 7.1% and 9.5% for the two cities, respectively, which was higher than that for other cities in China (1.5% and 5.9%). Of all the sampled children, 14.6% and 8.2% suffered anemia and diarrhea, respectively. Multivariate analysis showed that legumes or nuts fed in a 24-h recall increased the risk of anemia (OR=4.9). Children whose caregivers began to introduce complementary foods relatively late would have high diarrhea prevalence (OR=1.4). In conclusion, the prevalence of anemia and diarrhea in under-five children from urban low-income families in China is relatively high. The growth and nutritional status of these children is greatly affected by feeding practices. A series of measures should be taken by relevant government departments to improve the health of these children.

Synthesis and characterization of a cadmium(II)-organic supramolecular coordination compound based on the multifunctional 2-amino-5-sulfobenzoic acid ligand.

Much attention has been paid by chemists to the construction of supramolecular coordination compounds based on the multifunctional ligand 5-sulfosalicylic acid (H3SSA) due to the structural and biological interest of these compounds. However, no coordination compounds have been reported for the multifunctional amino-substituted sulfobenzoate ligand 2-amino-5-sulfobenzoic acid (H2asba). We expected that H2asba could be a suitable building block for the assembly of supramolecular networks due to its interesting structural characteristics. The reaction of cadmium(II) nitrate with H2asba in the presence of the auxiliary flexible dipyridylamide ligand N,N'-bis[(pyridin-4-yl)methyl]oxamide (4bpme) under ambient conditions formed a new mixed-ligand coordination compound, namely bis(3-amino-4-carboxybenzenesulfonato-κO1)diaquabis{N,N'-bis[(pyridin-4-yl)methyl]oxamide-κN}cadmium(II)-N,N'-bis[(pyridin-4-yl)methyl]oxamide-water (1/1/4), [Cd(C7H6NO5S)2(C14H14N4O2)2(H2O)2]·C14H14N4O2·4H2O, (1), which was characterized by single-crystal and powder X-ray diffraction analysis (PXRD), FT-IR spectroscopy, thermogravimetric analysis (TG), and UV-Vis and photoluminescence spectroscopic analyses in the solid state. The central CdII atom in (1) occupies a special position on a centre of inversion and exhibits a slightly distorted octahedral geometry, being coordinated by two N atoms from two monodentate 4bpme ligands, four O atoms from two monodentate 4-amino-3-carboxybenzenesulfonate (Hasba-) ligands and two coordinated water molecules. Interestingly, complex (1) further extends into a threefold polycatenated 0D→2D (0D is zero-dimensional and 2D is two-dimensional) interpenetrated supramolecular two-dimensional (4,4) layer through intermolecular hydrogen bonding. The interlayer hydrogen bonding further links adjacent threefold polycatenated two-dimensional layers into a three-dimensional network. The optical properties of complex (1) indicate that it may be used as a potential indirect band gap semiconductor material. Complex (1) exhibits an irreversible dehydration-rehydration behaviour. The fluorescence properties have also been investigated in the solid state at room temperature.

GLABROUS INFLORESCENCE STEMS regulates trichome branching by genetically interacting with SIM in Arabidopsis.

Arabidopsis trichomes are large branched single cells that protrude from the epidermis. The first morphological indication of trichome development is an increase in nuclear content resulting from an initial cycle of endoreduplication. Our previous study has shown that the C2H2 zinc finger protein GLABROUS INFLORESCENCE STEMS (GIS) is required for trichome initiation in the inflorescence organ and for trichome branching in response to gibberellic acid signaling, although GIS gene does not play a direct role in regulating trichome cell division. Here, we describe a novel role of GIS, controlling trichome cell division indirectly by interacting genetically with a key endoreduplication regulator SIAMESE (SIM). Our molecular and genetic studies have shown that GIS might indireclty control cell division and trichome branching by acting downstream of SIM. A loss of function mutation of SIM signficantly reduced the expression of GIS. Futhermore, the overexpression of GIS rescued the trichome cluster cell phenotypes of sim mutant. The gain or loss of function of GIS had no significant effect on the expression of SIM. These results suggest that GIS may play an indirect role in regulating trichome cell division by genetically interacting with SIM.
