Eosinophilia

Eosinophilia refers to an abnormal increase in the number of eosinophils, a type of white blood cell, in the body.
This condition can be associated with a variety of disorders, including allergic reactions, parasitic infections, and certain types of cancer.
Eosinophilia may cause symptoms such as tissue inflammation, organ damage, and complications depending on the underlying cause.
Effective diagnosis and treatment of eosinophilia requires a thorough understanding of the potential etiologies and appropriate management strategies.

The University of North Carolina (UNC) EoE clinico-pathologic database was used for this study. This database contains clinical, endoscopic, and pathologic characteristics on over 1,200 patients with esophageal eosinophilia from any cause from 2000 to 2007. It also contains information on patients in whom esophageal eosinophilia was excluded with a normal esophageal biopsy. Because this study was designed primarily to test reliability of determining eosinophil counts, subjects were selected based on their initial eosinophil counts (eos/hpf) performed for clinical care, and specifically chosen to represent a wide range of esophageal eosinophil counts, from 0 to >300 eos/hpf. The esophageal eosinophilia could have been from any cause, including EoE or gastroesophageal reflux disease, and clinical characteristics were not relevant for the purposes of this study. After identification of appropriate patients, archived pathology slides were pulled for review. This study was approved by the University of North Carolina Institutional Review Board.

Study participants were patients diagnosed with epilepsy by the Department of Neurology in Ningxia Medical University General Hospital. The inclusion criteria were as follows: ① Ningxia resident with no history of marriages with other ethnic groups for more than three generations; ② Clear indications for AEDs treatment; ③ Have not been administered oral AEDs, and potential adverse drug reactions declared in patients or their guardians, after which signed informed consents were obtained; and ④ The initial dose and increasing dose of AEDs determined according to the “Pharmacopeia of People's Republic of China” (2010 edition). The exclusion criteria were as follows: ① Having a history of alcohol-related epilepsy; ② Having a treatable cause (such as metabolic disorders, poisoning, and infection); ③ With progressive brain or central nervous system diseases, such as encephalitis, tumors, or degenerative diseases; ④ Suffering from other diseases and the emergence of allergy during the follow-up period; and ⑤ Having to discontinue or substitute medications and not completing 12 weeks of prescribed oral AEDs.
Four hundred and fifteen patients were followed up bi-weekly for 12 weeks after initiating oral AEDs. The initial dosage of PHT, LTG, CBZ, and valproate (VPA) was 200, 500, 12.5, 100 mg/d, and 5 mg/kg/d, respectively. They were examined for symptoms and signs of cADRs in an epileptic clinic every 2 weeks. AEDs tolerance was defined as patients who were able to tolerate AEDs without cADRs manifestation. If cADRs manifested, the AEDs were discontinued immediately and a dermatologist was consulted to diagnose and treat the patients (Figure 1).
Two attending or one chief physician from the Department of Dermatology examined the patients. The criteria for the diagnosis and classification of cADRs were as follows: ① MPE: a rash, not involving the mucosa, no organ or system damage, and resolved after 1–2 weeks; ② HSS: in addition to skin rash, numerous viscera involvement with systemic manifestations, such as fever, arthralgia, eosinophilia, and lymphadenopathy; ③ SJS: the occurrence of skin exfoliation, involving a range of no <10% of the body area, with or without other organ or system damage; ④ TEN: the presence of skin exfoliation, involving more than 30% of the body area, with or without other organ or system damage; and ⑤ SJS/TEN: the presence of skin exfoliation, involving a range of 10–30% of the total body area. The patients were treated for skin damage based on the severity as determined by a dermatologist after cADRs diagnosis was confirmed. These patients were assigned to the AEDs-cADRs group.
Nested case-control design is the most common way to reduce the costs of exposure assessment in prospective epidemiological studies. They can also reduce the sample size through matching (10 (link)). In this study, 15 patients with epilepsy who developed cADRs were defined as the AEDs-cADRs group. For each patient with AEDs-cADRs, two patients with AEDs tolerance were selected and matched by AEDs, gender, age (±3 years), and ethnicity.

TNM6 (Sobin and Wittekind, 2002 ) was used in staging and World Health Organization (WHO) criteria in grading the differentiation (Hamilton et al, 2010 ). The SACs were detected by the WHO 2010 criteria as described earlier (Hamilton et al, 2010 ; Sajanti et al, 2014 (link)), including saw-toothed epithelial serrations, clear or eosinophilic cytoplasm, vesicular nuclei with distinct nucleoli, well-preserved polarity, and abundant mucin production. Tumour growth pattern at the advancing tumour border was classified using the earlier described criteria (Jass et al, 1996 (link)), briefly diffuse, irregular clusters or small glands or cords of cells infiltrating to surrounding tissue vs expanding, well-circumscribed margins. Lymphatic invasion was defined as tumour cells present in vessels with an endothelial lining but lacking a muscular wall, and blood vessel invasion was evaluated positive if there were tumour cells in vessels with a thick muscular wall or in vessels containing red blood cells. The areal percentage of tumour necrosis was visually estimated by inspecting manually all available tumour slides. The method was otherwise analogous with two previous studies (Pollheimer et al, 2010 (link); Richards et al, 2012 (link)), but no predetermined cutoff scores were utilised in this study. Tumour necrosis in haematoxylin and eosin (H&E)-stained sections was specified as an area with increased eosinophilia and nuclear shrinkage, fragmentation and disappearance, with shadows of tumour cells visible to variable extent (Figure 1). Neutrophilic inflammatory infiltrate at the boundaries of an area was considered to support the classification of that area as necrotic but was not required by definition. Intraluminal necrosis fulfilled the criteria and was included in the evaluation of tumour necrosis percentage. All the histological analyses were performed blinded to the clinical data.

Nasal Cytology was performed by scraping the middle part of the inferior turbinate. For the sampling we used a sterile disposable curette (Nasal scraping®, Ep Medica (RA), Italy). The sample was immediately smeared on a glass slide, air dried and then stained with May–Grunwald–Giemsa preparation. The following reading by an optical microscope Nikon E600 (Nikon, Ontario, Canada) allowed us to identify the presence of inflammatory cells (neutrophils, eosinophils, lymphocytes and mast cells) in nasal mucosa. We analyzed a minimum of 50 microscopic fields at x 1000 in oil immersion and the count of each cell type was expressed by a semi-quantitative grading (from 0 to 4 (link)) (13 (link),14 (link)). During the nasal cytological examination at T0, the clinical-cytologic grading was also calculated for each patient. Since CRswNP is a pathology with an elevated risk of relapse and poor control despite conventional therapy, negative prognostic factors responsible of relapses and lack of symptoms control were identified (15 (link)). Many studies demonstrated that allergy, asthma, and acetylsalicylate (ASA) sensitivity are determining factor for negative outcomes. The correlation between these clinical parameters and nasal cytology results (nasal eosinophilia, neutrophilia, mastocytosis) led to the development of a score, called clinical-cytologic grading (CCG), whose value defines the relapse prognostic index, classified in low, intermediate, or high (Table 1) (16 (link)).

Statistical analyses were performed using SPSS software. The paired series involved a comparison test used to assess duration of effectiveness, pre- and postoperative differences in nasal obstruction VAS, olfactory disorders VAS and pre- and postoperative differences in NPS. The significance level was set at 0.05 for all analyses. The highest NPS from both the right and left nasal fossae was used for statistical analyses. Student’s mean comparison test was used to evaluate the influence of factors potentially affecting our results. Gender, asthma or AERD, history and number of sinus surgeries, preoperative NPS, hypereosinophilia, cardiovascular history and diabetes were tested. Survival analysis was performed using the Kaplan-Meier method to determine non-recurrence. The log-rank test was performed to evaluate the influence of factors potentially affecting recurrence.

Whole hearts were fixed in 10% buffered formalin at the end of each experiment, and sectioned transversely at midventricle, with samples taken from the anterior to lateral free LV wall for histological assessment. These were paraffin‐embedded, sectioned at 4 μm, and stained with H&E, and immunohistochemistry for von Willebrand factor (vWF). H&E‐stained sections were quantitatively scored in a blinded fashion by a pathologist. The extent of myocardial hemorrhaging on each section was scored as 0 (none), 1 (<10%), 2 (10%–50%), or 3 (>50%), with endocardial and epicardial hemorrhage also scored as 0 (none), 1 (<5%), 2 (5%–10%), or 3 (>10%). Contraction bands and/or hypereosinophilic myocytes were also assessed as 0 (absent), 1 (present). Staining for vWF was used as a marker for endothelial cell injury. After deparaffinization and rehydration, antigen retrieval (Dako Target Retrieval Solution, pH9, Agilent) was performed for subsequent probing with an anti‐vWF antibody (GA527, 1:400, Dako). An anti‐rabbit secondary antibody (VECTASTAIN Elite ABC‐Peroxidase kit, Vector Laboratories) and 3,3′‐diaminobenzidine (SigmaFAST DAB, Sigma‐Aldrich) were used for detection and staining. Hematoxylin was used for counterstaining. vWF density was expressed as a pixel unit and calibrated by the sum of inner perimeters of vessels in each section using Adobe Photoshop 2020 (Adobe, CA). The same threshold density for vWF‐positive staining was applied to all sections. To assess apoptosis, a TUNEL (terminal deoxynucleotidyl transferase biotin‐dUTP nick end labeling) assay was performed as per manufacturer's instructions (ApopTag Plus Fluorescein In Situ Apoptosis Detection Kit, EMD Millipore Corporation, CA), and the number of TUNEL‐positive nuclei was quantified in 6 randomly picked fields/sections with an open‐source digital image analysis software (QuPath v0.2.3) at 20X and averaged. TUNEL‐positive nuclei were expressed as a percentage of total nuclei.

Tissue samples were fixed in formalin, processed routinely, and stained with
hematoxylin and eosin. Histologic scores and diagnoses were made by consensus
(LAJH or LS, and JLC) without knowledge of the gross diagnosis or microbiology
data. All lung sections were scored for the presence or absence of specified
histologic lesions (Supplemental Tables S4 and S5). The duration of cranioventral
and caudodorsal lung lesions was classified as acute (absence of fibrosis),
subacute (presence of immature granulation tissue), or chronic (presence of
mature fibrosis that was densely eosinophilic with fewer and smaller fibroblast
nuclei).
Histologic criteria for diagnosis of bronchopneumonia were neutrophils and
macrophages filling the lumen of alveoli and bronchioles. Histologic criteria
for alveolar and bronchiolar damage (a form of interstitial/bronchointerstitial
lung disease) were alveoli lined by hyaline membranes or type II pneumocytes and
loss of bronchiolar epithelium with attenuation of remaining epithelial cells,
respectively. Cases were diagnosed as BIP if bronchopneumonia was a predominant
histologic lesion in sections of cranioventral lung and alveolar and bronchiolar
damage were prominent in sections of caudodorsal lung. However, the lesion types
were not required to be anatomically segregated: The cranioventral lung sections
of some BIP cases had alveolar and bronchiolar damage in addition to the
bronchopneumonia required for the diagnosis of BIP, and the caudodorsal lung
sections of some BIP cases had bronchopneumonia in addition to the alveolar and
bronchiolar damage required for the diagnosis of BIP.

In this part, we outline our suggested method for having the virtual doctor produce responses to patient inquiries that are appropriate from a medical standpoint. Figure 2 depicts the detailed model architecture proposed for the task of medical dialogue generation. We use the BioBERT BASE43 (link) as the pre-trained language model to dynamically build contextualised representations for the input sequences using graphical knowledge. With the conversation sequence C in hand, we first mask the tokens for which we acquire a medical graph gi in accordance with section “Construction of the medical entity graph”, and instead of predicting the token itself, we infer the tail entities extracted from the corresponding graphs. We call this as the MED model. For example, given the triples: ’(cough, treats, eosinophilia)’, ’(blockage, occurs in, pulmonologist)’, we mask the tokens cough and blockage in the dialogue context, as “i am continuously suffering from [MASK] due to feeling of some [MASK] in upper wind pipe”; the model then predicts the tail entity corresponding to the masked tokens cough and blockage i.e eosinophilia and pulmonologist. We choose the tail token from the first triple in the sequence (τ1,τ2,,τ|gi|) , associated with the m-th masked token and denote it as Tm . Given the input sequence, I (Each token in I is first passed through a series of three embedding layers (Token, Segment, and Position). The resulting embeddings are concatenated and denoted as Ebk,i ), we first attempt to predict ML by using BERT based token classification model which returns the hidden states, Hk,i , for the input sequence which is usually the representation of the [CLS] token. While predicting any masked token, information from nearby words is utilized. Our approach directly utilizes the dialogue context, (I) , simultaneously incorporating the knowledge triples.
We first form the flattened token sequence for the input utterance with the masked entities: I=[CLS],bk-1,1,[MASK],bk-1,3,,bk-1,|bk-1|,[SEP],dk-1,1,[MASK],,dk-1,|dk-1|,[SEP],bk,1,bk,2,[MASK],bk,4,bk,5,[MASK],bk,7,,bk,|bk|,[SEP]
The corresponding ground truth label, ML , for token classification is shown as follows: ML=[CLS],bk-1,1,T1,bk-1,3,,bk-1,|bk-1|,[SEP],dk-1,1,T2,,dk-1,|dk-1|,[SEP],bk,1,bk,2,T3,bk,4,bk,5,T6,bk,7,,bk,|bk|,[SEP] where the [CLS] token is inserted at the beginning of the sequence as an indicator of the start of the sentence. The [SEP] token distinguishes one sequence from the next and indicates the end of a sentence.
The BioBERT-based decoder generates text by predicting one word at a time, using the hidden state Hk,i at each time step. During training, the decoder is provided with the actual next word in the sequence, taken from the set RL , as input. However, during inference, the decoder uses the word it has previously predicted as input. To start the decoding process, the first input to the decoder is taken from the first token in RL . RL=[CLS],dk,1,dk,2,dk,3,dk,4,dk,5,dk,6,dk,7,,dk,|dk|,[SEP]
The BioBERT model uses its hidden state from the top layer, passed through a linear layer, to predict the next token in the target (output) sequence. P(yk,j)=softmaxW1[Hk,j]+b1 where W1 is a learnable weight matrix and b1 is the bias.
The decoder loss is the cross-entropy between the output distribution P(yk,j) and the reference distribution, dj , denoted as Loss=-djlog(P(yk,j)) .
