Spontaneous ovarian hyperstimulation syndrome and pituitary hyperplasia mimicking macroadenoma associated with primary hypothyroidism

We report an unusual case of spontaneous ovarian hyperstimulation syndrome and pituitary hyperplasia mimicking macroadenoma in an adult,non-pregnant woman.Her condition was triggered by unrecognized primary hypothyroidism,which regressed after thyroid hormone replacement therapy.This case highlights the need for clinicians and radiologists to familiarize themselves with the clinical and imaging features detected in case of these complications of primary hypothyroidism,which are not well known in the medical and radiological profession.Such improved knowledge will help avoid delays in diagnosis,progression to lifethreatening complications,and unnecessary surgery.

Depression of the elderly revealing a primary hypothyroidism

Introduction Psychiatric manifestations are exceptional during hypothyroidism and are not always easy to diagnose, especially since the clinical signs of hypothyroidism can be confused with those of the depressive syndrome. We report an original observation of depression of the elderly revealing an isolated primary hypothyroidism. Observation A 78-year-old patient, followed for essential hypertension, well-balanced under monotherapy with calcium channel blockers, and without degenerative complications, was referred by her family doctor for depressive syndrome not improved by the specific treatment prescribed and correctly taken for six months. The clinical examination noted in particular macroglossia with dental impressions and dry and cracked skin. The biological assessment showed hypothyroidism with TSH at 28μmol/l. Thyroid ultrasound showed atrophy of the thyroid gland. The thyroid autoimmunity (anti-thyroglobulin and anti-thyroperoxidase antibodies) was negative. The rest of the biological tests were in the normal range. The diagnosis of Riedel’s thyroiditis was retained and the patient was treated with levothyroxine in progressive doses until TSH normalization was achieved. The evolution on the psychiatric level was also favorable with disappearance of the signs of the depression and the anti-depressive treatment was discontinued. Conclusion Depression is rare, complicating only 4% of overt hypothyroidism and its diagnosis is not always easy, especially in the elderly. Hormone replacement therapy significantly improves the depressive syndrome and protects against cognitive decline. Thus, hypothyroidism screening seems appropriate for any depressive syndrome in the elderly.

Discovery of primary lung cancer following resection of rectal cancer lung metastasis:A case report

BACKGROUND Colorectal cancer(CRC)ranks high among the most common types of malignant tumors.The primary cause of cancer-related mortality is metastasis,with lung metastases accounting for 32.9%of all cases of metastatic CRC(MCRC).However,cases of MCRC in the lungs,which present concurrently with primary peripheral lung adenocarcinoma,are exceptionally rare.CASE SUMMARY This report describes the case of a 52-year-old female patient who,following a colonoscopy,was diagnosed with moderately differentiated adenocarcinoma based on rectal mucosal biopsy findings.A preoperative chest computed tomography scan revealed a ground-glass nodule in the right lung and a small nodule(approximately 0.6 cm in diameter)in the extramural basal segment of the left lower lobe,which suggested multiple lung metastases from rectal cancer.Subsequent treatment and follow-up led to a diagnosis of rectal cancer with left lung metastasis and peripheral adenocarcinoma of the lower lobe of the right lung.CONCLUSION This case report describes the therapeutic journey of a patient with lung metastasis from rectal cancer in addition to primary peripheral adenocarcinoma,thus underscoring the critical roles of multidisciplinary collaboration,personalized treatment strategies,and comprehensive patient rehabilitation guidance.

Three-dimensional choroidal vascularity index and choroidal thickness in fellow eyes of acute and chronic primary angle-closure using swept-source optical coherence tomography

AIM:To compare the three-dimensional choroidal vascularity index(CVI)and choroidal thickness between fellow eyes of acute primary angle-closure(F-APAC)and chronic primary angle-closure glaucoma(F-CPACG)and the eyes of normal controls.METHODS:This study included 37 patients with unilateral APAC,37 with asymmetric CPACG without prior treatment,and 36 healthy participants.Using swept-source optical coherence tomography(SS-OCT),the macular and peripapillary choroidal thickness and three-dimensional CVI were measured and compared globally and sectorally.Pearson’s correlation analysis and multivariate regression models were used to evaluate choroidal thickness or CVI with related factors.RESULTS:The mean subfoveal CVIs were 0.35±0.10,0.33±0.09,and 0.29±0.04,and the mean subfoveal choroidal thickness were 315.62±52.92,306.22±59.29,and 262.69±45.55μm in the F-APAC,F-CPACG,and normal groups,respectively.All macular sectors showed significantly higher CVIs and choroidal thickness in the F-APAC and F-CPACG eyes than in the normal eyes(P<0.05),while there were no significant differences between the F-APAC and F-CPACG eyes.In the peripapillary region,the mean overall CVIs were 0.21±0.08,0.20±0.08,and 0.19±0.05,and the mean overall choroidal thickness were 180.45±54.18,174.82±50.67,and 176.18±37.94μm in the F-APAC,F-CPACG,and normal groups,respectively.There were no significant differences between any of the two groups in all peripapillary sectors.Younger age,shorter axial length,and the F-APAC or F-CPACG diagnosis were significantly associated with higher subfoveal CVI and thicker subfoveal choroidal thickness(P<0.05).CONCLUSION:The fellow eyes of unilateral APAC or asymmetric CPACG have higher macular CVI and choroidal thickness than those of the normal controls.Neither CVI nor choroidal thickness can distinguish between eyes predisposed to APAC or CPACG.A thicker choroid with a higher vascular volume may play a role in the pathogenesis of primary angle-closure glaucoma.

Primary Hypothyroidism: Presence of Central Adiposity and Its Improvement on Attaining Euthyroid State with L-Thyroxine

Objective: Primary hypothyroidism is frequently manifested by weight gain. Moreover, treatment with L-Thyroxine reverses the weight gain in most subjects on achieving euthyroid state. However, the characteristic fat distribution contributing to these changes in body weight is not well documented. Therefore, the presence of central adiposity was examined in primary hypothyroidism prior to and after attaining and maintaining euthyroid state following L-Thyroxine therapy. Methods: Waist and hip measurements were conducted to determine waist: hip ratios in 55 men, ages 39 to 84 years at diagnosis of primary hypothyroidism established by subnormal Free T4 and supernormal TSH concentrations and again after their normalization by L-Thyroxine replacement therapy. The subjects were divided according to Body Mass Index (BMI-Kg/m2) into 3 groups;hypo T1, 20 men with BMI 30. 15 euthyroid normal (N) men matched for age and BMI in each group participated as controls. Results: Mean waist: hip ratio was significantly higher (p < 0.01) in subjects with primary hypothyroidism (0.97 + 0.03) than in healthy men (0.92 + 0.02) and declined significantly (p < 0.01) on achieving euthyroidism (0.93 + 0.02). Moreover, waist: hip ratios were also higher in individual hypothyroid groups;Hypo T1, 0.92 + 0.01 vs. N1, 0.88 + 0.01;Hypo T2, 0.96 + 0.02 vs. N2, 0.92 + 0.02 and Hypo T3, 1.02 + 0.03 vs. N3, 0.98 + 0.02 (p < 0.01for all comparisons). Finally, waist: hip ratios declined significantly in all groups on attaining euthyroidism;Hypo T1, 0.89 + 0.01;Hypo T2, 0.93 + 0.02;Hypo T3, 0.98 + 0.02 (p < 0.01 vs. pretreatment). Conclusion: Central adiposity is a definitive clinical manifestation of primary hypothyroidism in men. Moreover, a significant improvement on achieving euthyroid state following L-Thyroxine therapy may deem central adiposity to be a major contributor to changes in body weight in primary hypothyroidism noted at diagnosis and on attaining and maintaining euthyroid state.

Spatiotemporal changes of gross primary productivity and its response to drought in the Mongolian Plateau under climate change

Gross primary productivity(GPP)of vegetation is an important constituent of the terrestrial carbon sinks and is significantly influenced by drought.Understanding the impact of droughts on different types of vegetation GPP provides insight into the spatiotemporal variation of terrestrial carbon sinks,aiding efforts to mitigate the detrimental effects of climate change.In this study,we utilized the precipitation and temperature data from the Climatic Research Unit,the standardized precipitation evapotranspiration index(SPEI),the standardized precipitation index(SPI),and the simulated vegetation GPP using the eddy covariance-light use efficiency(EC-LUE)model to analyze the spatiotemporal change of GPP and its response to different drought indices in the Mongolian Plateau during 1982-2018.The main findings indicated that vegetation GPP decreased in 50.53% of the plateau,mainly in its northern and northeastern parts,while it increased in the remaining 49.47%area.Specifically,meadow steppe(78.92%)and deciduous forest(79.46%)witnessed a significant decrease in vegetation GPP,while alpine steppe(75.08%),cropland(76.27%),and sandy vegetation(87.88%)recovered well.Warming aridification areas accounted for 71.39% of the affected areas,while 28.53% of the areas underwent severe aridification,mainly located in the south and central regions.Notably,the warming aridification areas of desert steppe(92.68%)and sandy vegetation(90.24%)were significant.Climate warming was found to amplify the sensitivity of coniferous forest,deciduous forest,meadow steppe,and alpine steppe GPP to drought.Additionally,the drought sensitivity of vegetation GPP in the Mongolian Plateau gradually decreased as altitude increased.The cumulative effect of drought on vegetation GPP persisted for 3.00-8.00 months.The findings of this study will improve the understanding of how drought influences vegetation in arid and semi-arid areas.

Cardiac Malformations in Congenital Hypothyroidism: A Case Report

Introduction: Congenital hypothyroidism is the most common causes of preventable mental retardation. It is associated with other births defects like cardiac malformations. Descriptions in Sub Saharan Africa are rare, justifying the present report. Case Report: We reported the cases of 3 female patients, diagnosed with hypothyroidism, presenting in addition pulmonary stenosis. The diagnosis was late in all the patients and we noticed clinical improvement under levothyroxine. Conclusion: Association congenital hypothyroidism and cardiac defect is not rare. Our patients are female with no history of consanguinity, presenting congenital hypothyroidism with a gland in situ associated with pulmonary stenosis. Systematic screening of other births defects is thus recommended in affected patients.

The Correlation between Free Triiodothyronine, Free Thyroxine and Hypertension in Depression Patients with Hypothyroidism and Its Clinical Guiding Value

Background: Cardiovascular diseases, such as hypertension and coronary heart disease, are often accompanied by thyroid and mental diseases, the harm of which poses great threats to patients’ health. Objective: To explore the correlation between free triiodothyronine (FT3), free thyroxine (FT4) and hypertension in depression patients with hypothyroidism and its clinical guiding value. Methods: A total of 548 patients diagnosed with hypothyroidism in Wuxue First People’s Hospital of Hubei Province from January 2018 to September 2022 were enrolled. According to whether complicated with depression, they were divided into hypothyroidism without depression group (group A) and hypothyroidism with depression group (group B). The gender, age, comorbidities (such as depression, hypertension, diabetes, dyslipidemia, acute myocardial infarction), FT3, FT4, and thyroid stimulating hormone (TSH) levels were recorded. Spearman rank correlation was used to analyze hypertensive patients with hypothyroidism. Multivariate binary Logistic regression was used to analyze the influencing factors of hypertension in patients with hypothyroidism. Results: The TSH level, the number of hypertension, coronary heart disease and hyperlipidemia in group B were statistically significantly higher than those in group A (P 3 level in group B was statistically significantly lower than that in group A (P s = 0.092), coronary heart disease (rs = 0.000), hyperlipidemia (rs = 0.000), diabetes (rs = 0.000), and age (rs = 0.000), and negatively correlated with FT3 (rs = 0.000) (P 3 and FT4 were the influencing factors of hypertension. The risk of hypertension in patients with coronary heart disease and hyperlipidemia significantly increased by 3.425 and 1.761 times (P 3, the risk of hypertension increased (P 4, the risk of hypertension significantly increased (P 3 and FT4 are the influencing factors of hypertension. The lower the FT3 level, the higher the FT4 level, the higher the risk of hypertension. FT3 and FT4 may be potential biomarkers of depression in hypertensive patients. Thyroid function assessment is recommended in patients with hypertension.

Acute primary angle closure during the Omicron outbreak

AIM:To investigate Omicron’s impact on clinical presentation of acute primary angle closure(APAC)in China.METHODS:A consecutive case series with historical controls was conducted at Shenzhen Eye Hospital,the largest specialized hospital in Shenzhen,China.Medical records from a two-month period during the Omicron pandemic(December 1,2022,to January 31,2023)were compared with records from two control groups(12/2018–1/2019 and 12/2021–1/2022)before pandemic.Patients with APAC were included,and the prevalence of APAC and demographic characteristics in Omicron-infected and noninfected patients were compared.RESULTS:Seventy-one(23.43%)out of 303 patients were diagnosed with APAC in the pandemic cohort,which was 2.98 and 2.61 times higher than that in control cohorts(7.87%in 2019,8.96%in 2022,P<0.001).The pandemic cohort has significantly higher Omicron-infected rate(78.87%vs 0 vs 0;P<0.001),lower proportion of glaucoma history(16.90%vs 42.86%vs 41.67%,P=0.005),higher surgical rate(95.77%vs 83.33%vs 78.57%,P=0.024),higher total medical costs and larger pupil diameter(5.63±0.15 vs 4.68±0.15 vs 4.69±0.22 mm,P<0.01).In 83%Omicron-infected patients,ocular symptoms appeared within 3d after systemic symptoms onset.In multivariate analysis,Omicron infection(P<0.001)was the only independent predictor of pupil diameter.CONCLUSION:In the Omicron epidemic in China,there is an increase of prevalence and severity of APAC,particularly focusing on the first 3d following infection.

How forest age impacts on net primary productivity: Insights from future multi-scenarios

Forest net primary productivity(NPP)constitutes a key flux within the terrestrial ecosystem carbon cycle and serves as a significant indicator of the forests carbon sequestration capacity,which is closely related to forest age.Despite its significance,the impact of forest age on NPP is often ignored in future NPP projections.Here,we mapped forest age in Hunan Province at a 30-m resolution utilizing a combination of Landsat time series stack(LTSS),national forest inventory(NFI)data,and the relationships between height and age.Subsequently,NPP was derived from NFI data and the relationships between NPP and age was built for various forest types.Then forest NPP was predicted based on the NPP-age relationships under three future scenarios,assessing the impact of forest age on NPP.Our findings reveal substantial variations in forest NPP in Hunan Province under three future scenarios:under the age-only scenario,NPP peaks in 2041(133.56TgC·yr^(−1)),while NPP peaks three years later in 2044(141.14TgC·yr^(−1))under the natural development scenario.The maximum afforestation scenario exhibits the most rapid increase in NPP,with peaking in 2049(197.95TgC·yr^(−1)).However,with the aging of the forest,NPP is projected to then decrease by 7.54%,6.07%,and 7.47%in 2060,and 20.05%,19.74%,and 28.38%in 2100,respectively,compared to their peaks under the three scenarios.This indicates that forest NPP will continue to decline soon.Controlling the age structure of forests through selective logging,afforestation and reforestation,and encouraging natural regeneration after disturbance could mitigate this declining trend in forest NPP,but implications of these measures on the full forest carbon balance remain to be studied.Insights from the future multi-scenarios are expected to provide data to support sustainable forest management and national policy development,which will inform the achievement of carbon neutrality goals by 2060.

Clinical analysis of multiple primary gastrointestinal malignant tumors:A 10-year case review of a single-center

BACKGROUND Multiple primary malignant tumors(MPMTs)was first described by Billroth as early as 1889,with the first report published by Warren and Gates in 1932.Since then,numerous cases have been reported.A literature review of 1104269 patients with cancer revealed that the incidence of MPMTs ranged from 0.73 to 11.7%.In recent years,however,there has been a significant upward trend in the incidence of this phenomenon,which may be associated with many different factors,including the advancement of modern diagnostic procedures facilitating the examination and diagnosis of more MPMTs,increased exposure to chemotherapy and radiotherapy that exacerbate the risk of new malignant tumors in patients with cancer,and prolonged survival of patients with cancer allowing sufficient time for the development of new primary cancers.AIM To analyze the incidence,clinical features,treatment factors,prevalence,and prognosis of patients with MPMTs in the gastrointestinal tract treated in a single center.Additionally,we analyzed the different tumor combinations,time interval between the occurrence of tumors,and staging.METHODS This retrospective cohort study analyzed 8059 patients with pathologically confirmed gastrointestinal malignant tumors treated at the Gansu Province Hospital in Lanzhou,Gansu,China between June 2011 and June 2020.Of these,85 patients had MPMTs.The clinical features,treatment factors,prevalence,and prognosis of this latter cohort were analyzed.RESULTS The incidence of MPMTs in patients with gastrointestinal malignant tumors was 1.05%(85/8059),including 83 double primary malignant tumors and two triple primary malignant tumors of which 57(67.06%)were synchronous MPMTs(SMPMTs)and 28(32.94%)were metachronous MPMTs(MMPMTs).The most frequent associations were found between the rectum colon cancers within the SMPMT category and the gastric-colon cancers within the MMPMT category.For the MMPMTs,the median interval was 53 months.The overall 1-,3-and 5-year survival rates from diagnosis of the first primary cancer were 91.36%,65.41%,and 45.97%,respectively;those from diagnosis of the second primary cancer were 67.90%,29.90%,and 17.37%,respectively.CONCLUSION MPMTs in the gastrointestinal tract have a high incidence and poor prognosis.Thus,it is necessary to perform both gastroscopy and colonoscopy in patients with gastrointestinal tumors.Multidisciplinary comprehensive diagnosis and treatment may improve the diagnosis rate and treatment efficiency of MPMTs.

Efficacy and safety of transhepatic arterial chemoembolization with drug-loaded microspheres in unresectable primary liver cancer

BACKGROUND Transhepatic arterial chemoembolization(TACE),as a local treatment,has been widely used in the treatment of unresectable liver cancer.The introduction of drug carrier microspheres has brought new hope for the therapeutic effect of TACE.Microspheres can realize the slow release and directional delivery of drugs,reduce systemic toxicity and improve local curative effect.AIM To compare the effectiveness of traditional transcatheter arterial chemoembolization against microsphere-assisted transcatheter arterial chemoembolization in the treatment of hepatocellular carcinoma that is incurable.METHODS We searched the PubMed,Embase,Cochrane Library,and CNKI databases for clinical trials of drug-luting beads TACE(DEB-TACE)vs conventional TACE(cTACE)for the treatment of unresectable liver cancer.We screened references based on inclusion and exclusion criteria and then selected valid data for meta-analysis using RevMan 53 software.The complete response(CR)rate,partial response(PR)rate,postoperative stable disease(SD)rate,and 6-month and 12-month survival rates were compared.RESULTS A total of 12 articles were included,including 1177 patients,519 of whom received DEB-TACE and 658 of whom received cTACE.The CR rate in the DEB-TACE group was much greater than that in the cTACE group[relative risk(RR)=1.42,95%CI:1.18-1.72,P=0.0002].The 12-month survival rate significantly increased(RR=1.09;95%CI:1.01-1.17,P=0.03);the PR rate(RR=1.13;95%CI:0.97-1.30,P=0.12);the SD rate(RR=0.82;95%CI:0.64-1.05,P=0.12);and the 6-month survival rate(RR=1.05;95%CI:1.00-1.10,P=0.07).There was no significant difference(P<0.05).CONCLUSION Compared with those of iodized oil TACE,the drug-loaded microspheres tended to have therapeutic advantages.

MP-3 microperimeter in early primary open angle glaucoma with a new pattern

AIM:To investigate macular microperimetry in patients with early primary open angle glaucoma(POAG)using a new custom-made pattern,and analyze the characteristics of macular sensitivity.METHODS:This case-control study included 38 patients with POAG,who were divided into pre-perimetric glaucoma(18 eyes of 18 patients),early-stage(20 eyes of 20 patients),and control(20 eyes of 20 patients)groups.All subjects underwent standard 24-2 humphrey visual field test.An MP-3 microperimeter with a new custom-made pattern(28 testing points distributed in four quadrants,covering the central 10°of the retina)was used to evaluate macular sensitivity.Ganglion cell complex(GCC)thicknesses were examined using an RS-3000 Advance OCT system.The features of structure and function were analysed per quadrant.RESULTS:The pre-perimetric glaucoma group had significantly lower inferior hemifield macular sensitivity compared to controls(P<0.05).The early-stage POAG group had significantly lower average,inferior hemifield,inferonasal,and inferotemporal mean sensitivities compared to the pre-perimetric glaucoma group(P<0.05),and lower macular sensitivity in all sectors compared to controls(P<0.05).Regarding GCC thickness,all sectors in the early-stage POAG group became thinner compared to those in controls(P<0.05);whereas all sectors in the early-stage POAG group,except the superonasal quadrant,became thinner compared to those in the pre-perimetric glaucoma group(P<0.05).Macular sensitivity and GCC thickness were significantly associated in each sector.The inferotemporal quadrant had the highest correlation coefficients(0.840).The structure-function relationship for the inferonasal and inferotemporal sectors was stronger compared to the corresponding superior sectors.CONCLUSION:Microperimetry reveals variations in macular sensitivity in patients with early glaucoma earlier than conventional perimetry,particularly in pre-perimetric glaucoma cases in which it might be undetectable by conventional methods.The new custom-made pattern may improve the accuracy of microperimetry by enhancing point arrangement and reducing fatigue effects.Macular sensitivity measured by MP-3 with this pattern shows statistically significant structural and functional associations with the thicknesses of the GCC.

Evaluation of Well Spacing for Primary Development of Fractured Horizontal Wells in Tight Sandstone Gas Reservoirs

Methods for horizontal well spacing calculation in tight gas reservoirs are still adversely affected by the complexity of related control factors,such as strong reservoir heterogeneity and seepage mechanisms.In this study,the stress sensitivity and threshold pressure gradient of various types of reservoirs are quantitatively evaluated through reservoir seepage experiments.On the basis of these experiments,a numerical simulation model(based on the special seepage mechanism)and an inverse dynamic reserve algorithm(with different equivalent drainage areas)were developed.The well spacing ranges of Classes I,II,and III wells in the Q gas field are determined to be 802–1,000,600–662,and 285–400 m,respectively,with their average ranges as 901,631,and 342.5 m,respectively.By considering both the pairs of parallel well groups and series well groups as examples,the reliability of the calculation results is verified.It is shown that the combination of the two models can reduce errors and provide accurate results.

Bruton’s tyrosine kinase inhibitors in primary central nervous system lymphoma:New hopes on the horizon

In this editorial,we comment on the article by Wang et al.This manuscript explores the potential synergistic effects of combining zanubrutinib,a novel oral inhibitor of Bruton’s tyrosine kinase,with high-dose methotrexate(HD-MTX)as a therapeutic intervention for primary central nervous system lymphoma(PCNSL).The study involves a retrospective analysis of 19 PCNSL patients,highlighting clinicopathological characteristics,treatment outcomes,and genomic biomarkers.The results indicate the combination’s good tolerance and strong antitumor activity,with an 84.2%overall response rate.The authors emphasize the potential of zanubrutinib to modulate key genomic features of PCNSL,particularly mutations in myeloid differentiation primary response 88 and cluster of differentiation 79B.Furthermore,the study investigates the role of circulating tumor DNA in cerebrospinal fluid for disease surveillance and treatment response monitoring.In essence,the study provides valuable insights into the potential of combining zanubrutinib with HD-MTX as a frontline therapeutic regimen for PCNSL.The findings underscore the importance of exploring alternative treatment modalities and monitoring genomic and liquid biopsy markers to optimize patient outcomes.While the findings suggest promise,the study’s limitations should be considered,and further research is needed to establish the clinical relevance of this therapeutic approach for PCNSL.

Heterochronous multiple primary prostate cancer and lymphoma:A case report

BACKGROUND Multiple primary malignant tumors(MPMTs)are rare type of cancer,especially when solid tumors are the first and lymphoma is the second primary malignancy.We report a patient with heterochronous MPMTs consisting of prostate cancer and rectal diffuse large B-cell lymphoma(DLBCL).CASE SUMMARY We report a 77-year-old male patient diagnosed with prostate cancer who was treated with radiation therapy and one year of endocrine therapy with bicalutamide(50 mg per day)and an extended-release implant of goserelin(1/28 d).Seven years later,rectal DLBCL with lung metastases was found.CONCLUSION Although rare,the possibility of prostate cancer combined with a double primary cancer of DLBCL can provide a deeper understanding.

Decomposition and decoupling effect of energy eco-footprint based on global net primary productivity in urban agglomerations

Net primary productivity(NPP)is an important breakthrough point of current research on ecological footprint improvement.The energy eco-footprint(EEF)of the Four-City Area in Central China(FCACC)was measured by constructing an EEF-NPP model.This work has made the following efforts:(1)Gini coefficient was employed to analyze the degree of matching between the EEF and economic growth,population,and energy consumption.(2)LMDI decomposition method was used to explore the impacts of multiple factors on the EEF in the FCACC.(3)Tapio decoupling model was applied to verify the decoupling relationships between the above influencing factors and the EEF.(4)LMDI decomposition formula was embedded into the decoupling model to analyze the impacts of technical and non-technical factors on the decoupling elasticity of the above.The main findings show that from 2010 to 2020:(1)the degree of matching of EEF-GDP,EEF-population,and EEF-energy consumption increased.(2)energy intensity and per capita GDP were the main factors that affected the EEF.(3)the decoupling states between total energy consumption,energy consumption structure,energy intensity,per capita GDP,and population size with the EEF were expansive negative decoupling,expansive negative decoupling,strong negative decoupling,weak decoupling,and expansive negative decoupling,respectively.(4)the impact of non-technical factors was greater than that of technical factors,and their impacts were always in opposite directions.

Correlation Study of Aortic Velocity Propagation, Abdominal Aortic Intima-Media Thickness, and Epicardial Adipose Tissue Thickness in Subclinical Hypothyroidism Patients

Objective:To explore the correlation between epicardial fat thickness(EFT),aortic velocity propagation(AVP),and abdominal aortic intima-media thickness(AA-IMT)in patients with subclinical hypothyroidism(SH).Additionally,to compare these indicators between SH patients and healthy individuals,providing a new theoretical basis for the clinical prevention and treatment of cardiovascular diseases.Method:Clinical data from 50 SH patients(23 males and 27 females)and 50 healthy outpatient examinees(22 males and 28 females)were analyzed.The participants were selected from January 2022 to December 2023 at Loudi Central Hospital.EFT,AVP,and AA-IMT were measured,and their correlations were analyzed.Results:SH patients had significantly higher EFT and AA-IMT levels than the control group,while their AVP was significantly lower,with these differences being statistically significant(P<0.05).Correlation analysis revealed a significant negative correlation between EFT and AVP(P<0.001),a significant positive correlation between EFT and AAO-IMT(P<0.001),and a significant negative correlation between AVP and AAO-IMT(P<0.001).Multivariate binary logistic regression analysis identified increased EFT,decreased AVP,and increased AAO-IMT as independent risk factors for SH patients.Conclusion:In SH patients,EFT and AAO-IMT are elevated,whereas AVP is reduced.EFT and AVP are significantly correlated with AAO-IMT.EFT and AAO-IMT can serve as reliable indicators for evaluating subclinical atherosclerosis in SH patients,providing a diagnostic basis for clinical practice.

Three novel rare TP53 fusion mutations in a patient with multiple primary cancers:a case report

As survival rates improve and detection technologies advance,the occurrence of multiple primary cancers(MPCs)has been increasing.Approximately 16%of cancer survivors develop a subsequent malignancy,with lung cancer often developing after esophageal cancer due to potential“field cancerization”effects.Despite this observation,the genetic heterogeneity underlying MPCs remains understudied.However,the recent emergence of genetic testing has expanded the scope of investigations into MPCs to investigate signatures underlying cancer predisposition.This report reveals 3 unprecedented TP53 fusion mutations in a Chinese patient afflicted by MPCs,namely,AP1M2–TP53(A1;T11)fusion,TP53–ILF3(T10;I13)fusion,and SLC44A2–TP53(S5;T11)fusion.This patient exhibited an extended period of survival after diagnosis of extensive-stage small cell lung cancer,which occurred 6 years after the diagnosis of esophageal squamous cell cancer.This unique reportmay provide supplementary data that enhance our understanding of the genetic landscape ofMPCs.
