Value of Echocardiography and Cardiac Magnetic resonance in assessing left ventricular function in breast and gastric cancer patients after Anthracycline Chemotherapy.

BACKGROUND: Echocardiography (ECHO) and cardiac magnetic resonance imaging (MRI) are used to observe changes in the left ventricular structure in patients with breast and gastric cancer after 6 cycles of chemotherapy. Based on the observed values, we aimed to evaluate the cardiotoxicity of anthracyclines in cancer patients and to analyze the consistency of the two examination methods in assessing left ventricular function after chemotherapy. METHODS: From January 2020 to January 2022, the data of 80 patients with malignant tumors who received anthracycline chemotherapy (breast cancer, n = 40; gastric cancer, n = 40) and 40 healthy volunteers (Control group) were retrospectively collected. Serum high-sensitivity cardiac troponin T (hs-cTnT) levels were detected by an automatic immunoassay analyzer. Left ventricular end-systolic volume (LVESV), left ventricular end-diastolic volume (LVEDV) and left ventricular ejection fraction (LVEF) were measured by cardiac MRI and 2-dimensional ECHO using the biplane Simpson's method. RESULTS: Compared with baseline values, serum high-sensitivity cardiac troponin T (hs-cTnT) levels were significantly increased in patients with breast cancer and gastric cancer after 6 cycles of chemotherapy (P < 0.05). In addition, LVEDV, LVESV and LVEF measured with MRI were higher than those detected by ECHO in cancer patients after 6 cycles of chemotherapy (P < 0.05). And the Bland-Altman plot analysis showed that LVEDV, LVESV and LVEF measured by the two examination methods were in good agreement. CONCLUSION: Breast and gastric cancer patients exhibited elevated levels of hs-cTnT after 6 cycles of chemotherapy, indicating potential cardiotoxicity. Additionally, cardiac MRI and 2-dimensional ECHO showed good agreement in assessing left ventricular function, with ECHO tending to underestimate volume measurements compared to MRI.

Sonographic hypoechogenicity of brainstem raphe nucleus is correlated with electroencephalographic spike frequency in patients with epilepsy.

BACKGROUND: Brainstem raphe nucleus (BRN) hypoechogenicity in transcranial sonography (TCS) has been demonstrated in patients with major depression, possibly representing a sonographic manifestation of serotonergic dysfunction in depression. Most patients with epilepsy with comorbid depression exhibit hypoechogenic BRN in TCS. However, the role of BRN in the pathogenesis of epilepsy is unclear. This study aimed to evaluate the correlation of BRN echogenicity with epilepsy itself, and the echogenicity of other midbrain structures and the size of lateral ventricle (LV) will also be evaluated in patients with epilepsy. METHODS: Thirty-six patients with epilepsy without depression and 37 healthy controls were recruited. Sonographic echogenicity of BRN, caudate nucleus (CN), lentiform nucleus (LN), substantia nigra (SN), and the width of frontal horns of the lateral ventricles (LV) and the third ventricle (TV) were evaluated with TCS. The frequency of interictal epileptiform discharges (IEDs) was assessed with ambulatory electroencephalogram (AEEG). RESULTS: Hypoechogenicity of BRN was depicted in 36.1% of patients with epilepsy and 18.9% of controls, showing no significant difference. Patients with epilepsy with BRN hypoechogenicity had higher epileptic discharge index (EDI) than those with normal BRN echogenecity. Especially, higher EDI in patients with BRN hypoechogenicity was observed during the sleep period but not during awake period. The width of TV was significantly larger in patients with epilepsy than that in controls. We did not find any difference between patients with epilepsy and controls in the echogenicity of CN, LN, and SN, as well as in the width of frontal horn of LV. CONCLUSIONS: Hypoechogenic BRN is correlated with a high frequency of epileptic discharges in electroencephalogram (EEG), especially during sleep period but not during awake period, indicating that BRN alterations may play a potential role in the pathogenesis of epilepsy in association with sleep cycle.

A transcranial sonography study of brainstem and its association with depression in idiopathic generalized epilepsy with tonic-clonic seizures.

Brainstem raphe (BR) hypoechogenicity in transcranial sonography (TCS) has been depicted in patients with depression. But, up to date, the association of BR alterations in TCS with depression in patients with epilepsy has never been reported. This study was to investigate the possible role of BR examination via TCS in patients with idiopathic generalized epilepsy with tonic-clonic seizures (IGE-TCS) and depression. Forty-six patients with IGE-TCS and 45 healthy controls were recruited. Echogenicity of the caudate nuclei (CN), lentiform nuclei (LN), substantia nigra (SN), and BR and widths of the lateral ventricle (LV) frontal horns and the third ventricle (TV) were assessed via TCS. The determination of depression was based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV), and depression severity measured by Chinese version Neurological Disorders Depression Inventory for Epilepsy (C-NDDI-E) and Beck Depression Inventory-II (BDI-II). The width of TV in patients with epilepsy was found significantly larger than that in healthy controls (p = 0.001), but there was no significant difference in TV width between patients with IGE-TCS with and without depression. There were no significant differences between patients with IGE-TCS and healthy controls in LV frontal horn width, as well as in SN, CN, LN, and BR echogenicity. Here, it seems that patients with IGE-TCS were detected with smaller SN echogenic area compared with controls though they had no statistical significance. Patients with IGE-TCS with hypoechogenic BR had significantly higher C-NDDI-E and BDI-II scores than those with normal BR signal, and most patients with IGE-TCS with depression exhibited hypoechogenic BR, but few patients with IGE-TCS without depression exhibited hypoechogenic BR. In conclusion, BR echogenic signal alterations in TCS can be a biomarker for depression in epilepsy, but it might not be associated with epilepsy itself. The alterations of SN echogenic area and TV width in TCS may reflect a potential role of SN and diencephalon structure in the pathogenesis of epilepsy, which needs to be further elucidated.

Hypoechogenicity of brainstem raphe correlates with depression in migraine patients.

BACKGROUND: Brainstem raphe (BR) hypoechogenicity in transcranial sonography (TCS) has been depicted in patients with major depression (MD) and in depressed patients with different neurodegenerative diseases. But, up to date, the association of BR alterations in TCS with depression in migraineurs has never been reported. This study was to investigate the possible role of BR examination via TCS in migraineurs with depression. METHODS: Forty two migraine without aura (MwoA) patients and 40 healthy controls were recruited. Echogenicity of lentiform nuclei (LN), caudate nuclei (CN), substantia nigra (SN) and brainstem raphe (BR) and width of the frontal horns of the lateral ventricles and the third ventricle were assessed with TCS. The diagnosis of depression was based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders IV (DSM -IV), and the severity of depression was measured by Hamilton Rating Scale for Depression (HAM-D) and Hospital Anxiety and Depression Scale depression subscale (HADS-D). RESULTS: There were no significant differences between migraineurs and controls in the width of frontal horn of the lateral ventricle (p = 0.955), width of third ventricle (p = 0.129) as well as in the echogenicity of SN (p = 0.942), CN (p = 0.053), LN (p = 0.052) and BR (p = 0.677). Here, it seems that more migraineurs were detected with increased echogenecity of CN and LN compared with controls (33.3% versus 15.0% for CN, 19.0% versus 5.0% for LN) though they had no statistical significance. Patients with hypoechogenic BR had significantly higher HAM-D and HADS-D scores than those with normal BR signal (p = 0.000 for both HAM-D and HADS-D), and most (83.33%) migraineurs with depression exhibited hypoechogenic raphe but none (0.00%) of the migraineurs without depression exhibited hypoechogenic raphe (p = 0.000). CONLUSIONS: TCS signal alteration of BR can be a biomarker for depression in migraine but it is not associated with migraine headache itself. LN and CN alterations in TCS may reflect a potential role of them in the pathogenesis of migraine, which needs to be further elucidated.

[Clinical evaluation of the heart function early after repair of tetralogy of Fallot: follow-up of 43 patients].

OBJECTIVE: To evaluate the heart function of the patients early after the repair of tetralogy of Fallot (TOF). METHODS: Forty-three patients with TOF, 25 males and 18 females, underwent operation at the age of 2.5 - 52 years (16.7 years on average) and were followed up for 1 - 3.5 years. Twenty-one age-matched healthy persons were used as controls. Tissue Doppler imaging (TDI) was used to measure the values of the peak tricuspid ring velocity during early diastole (Ea), late diastole (Aa), systole, and isovolumic contraction, and isovolumetric contraction acceleration (IVA); and isovolumetric contraction time (ICT), isovolumetric relaxation time (IRT), and isovolumetric contraction velocity (IVV) of the right ventricle. Tei index was calculated using the formula: (ICT + IRT)/ET. Treadmill test was used on the patients aged > 17 to measure the maximal heart rate maximal blood pressure, maximal exercise tolerance (MET), and movement time. RESULTS: The peak tricuspid ring velocity during Ea of the repaired TOF group (rTOF group) was 11.5 +/- 2.6 cm/s, significantly lower than that of the control group (17.1 +/- 2.4 cm/s, P < 0.0001), the peak tricuspid ring velocity during Aa of the rTOF group was 9.6 +/- 1.7 cm/s, significantly lower than that of the control group (12.9 +/- 2.9 cm/s, P < 0.001), the E/A of the rTOF group was 1.16 +/- 0.36, significantly lower than that of the control group (1.36 +/- 0.26, P < 0.05). The IVV of the rTOF group was 7.7 +/- 1.8 cm/s, significantly lower than that of the control group (9.9 +/- 1.4 cm/s, P = 0.0030, and the IVA of the rTOF group was 131.7 +/- 37.6 cm/s(2), significantly lower than that of the control group (222.5 +/- 39.2 cm/s(2), P < 0.001). The Tei index of the rTOF group was 0.58 +/- 0.11, significantly higher than that of the control group (0.52 +/- 0.04, P = 0.029). The maximal heart rate maximal blood pressure, MET, and movement time of the rTOF group were all significantly lower than those of the control group (P < 0.05 or P < 0.01). CONCLUSION: The heart function of the patients undergoing repair of TOF fails to recover to the normal level during a short time after the surgery.

Right ventricular dysfunction due to right ventricular outflow tract patch.

Doppler tissue imaging analysis was used to examine the relationship between right ventricular function and right ventricular outflow tract damage in 54 patients with repaired tetralogy of Fallot. The patients were divided into three groups: 16 in whom the right ventricular outflow tract was directly sutured (group DS), 23 who had transventricular patch repair (group TVP), and 15 who had transannular patch repair (group TAP). The control group consisted of 16 age-matched patients who underwent patch closure of a ventricular septal defect (group C). The Tei index was obtained from tricuspid and pulmonary Doppler flow velocities. The right ventricular Tei index was significantly greater in groups TVP and TAP than in group DS. Doppler tissue imaging analysis in groups TVP and TAP showed shorter myocardial systolic velocity, diastolic peak velocity, and atrial diastolic peak velocity, lower peak myocardial velocity and acceleration during isovolumic contraction, and prolonged isovolumic relaxation and contraction times compared to groups DS and C. Right ventricular dysfunction is due to the right ventricular outflow tract patch. Thus, the right ventricular outflow tract may be essential for right ventricular ejection and maintenance of right ventricular function.
